柴油

首页 > 试题列表 > 单题解析

218039. （2023•长安区•高三上一月）     We are all aware of the damaging pollution that's created by driving petrol and diesel （柴油） vehicles.Many of the world's cities are blocked with traffic，creating fumes containing gases such as nitrogen oxides.The solution for a cleaner，greener future could be electric vehicles.But how optimistic should we be？There was much excitement last year when the UK government announced it will ban the sale of new petrol and diesel cars from 2030.But is that easier said than done？
    The road to global traffic being totally electric is still a long way off.Currently，battery life is an issue —a fully charged battery won't take you as far as a full tank of petrol.There are also limited numbers of charging points to plug an EV into.Of course，technology is always improving.Some of the biggest tech companies，like Google and Tesla，are spending huge amounts of money developing electric cars.And most of the big car manufacturers are now making them too.
    Colin Herron，a consultant on low-carbon vehicle technology，told the BBC： "The big leap forward will come with solid state batteries，which will appear first in mobile phones and laptops before they progress to cars." These will charge more quickly and give cars a bigger range.Cost is another issue that may discourage people from switching to electric power.But some countries offer incentive，such as cutting prices by reducing import taxes，and not charging for road tax and parking.Some also provide exclusive lanes for electric cars to be driven on，overtaking traditional cars which might be stuck in jams.
    These kinds of measures have made Norway the country with the most electric cars per capita （人均） at more than thirty electric cars per 1000 inhabitants.But Colin Herron warns that "electric motoring" doesn't mean a zero-carbon future. "It's emission-free motoring，but the car has to be built，the battery has to be built，and the electricity does come from somewhere." Maybe it's time to think about making fewer journeys or using public transport.

（1）Which statement can we infer from the question at the end of Paragraph 1？
A．Electric vehicles may not solve the traffic problems.
B．Probably it is hard to procure a greener future by means of electric vehicles.
C．We should not be too optimistic about the future.
D．It's not a good idea to replace petrol vehicles with electric ones.
（2）What does the underlined word "incentive" mean in Paragraph 3？
A．Improvements.
B．Drawbacks.
C．Communications.
D．Bonuses.
（3）According to the passage，which opinion the author might agree to？
A．Putting solid-state batteries in electric cars first will be a "great leap forward".
B．There are four obstacles on the road to global traffic being totally electric.
C．Electric cars might not get stuck in traffic jams in the future.
D．Electric motoring will create a zero-carbon future.
（4）What is the most suitable title for the text？
A．Total Electric Traffic：a Long Way to Go.
B．Electric Power or Petrol：a Tough Decision to Make.
C．Petrol and Diesel Vehicles：a Main Source of Gases.
D．Electric Vehicles：a Road to a Modern Society.

（1）推理判断题。根据第一段But is that easier said than done？（但这说起来容易做起来难吗？）还有第二段The road to global traffic being totally electric is still a long way off.（实现全球交通完全电动化的道路还有很长的路要走。）可知，作者在第一段最后提出疑问是想说明通过电动汽车来实现环保或许并不容易。故选B。
（2）词义猜测题。根据划线词所在句的前一句Cost is another issue that may discourage people from switching to electric power.（成本是另一个可能阻碍人们转向电力的问题。）可知，成本问题阻碍人们使用电动汽车。划线词后面的such as cutting prices by reducing import taxes，and not charging for road tax and parking（例如通过降低进口税来降低价格，不收取道路税和停车费）是对incentive的进一步说明，通过降低进口税来降低价格以及不收取道路税和停车费等措施有助于降低成本，由此可推测出，这是政府给予的激励措施，incentive意为"激励措施"，与bonuses（额外好处）意思最接近。A．Improvements提高；B．Drawbacks缺点；C．Communications交流；D．Bonuses额外好处。故选D。
（3）推理判断题。根据第三段中的Some also provide exclusive lanes for electric cars to be driven on，overtaking traditional cars which might be stuck in jams.（一些国家还为电动汽车提供专用车道，超越可能陷入拥堵的传统汽车。）可知，电动汽车在未来可能不会陷入交通堵塞。故选C。
（4）标题归纳题。通读全文，尤其是第二段The road to global traffic being totally electric is still a long way off.（实现全球交通完全电动化的道路还有很长的路要走。）可知，本文主要讲述了虽然电动汽车更加清洁、更加环保，但实现全球交通电动化还有很长的路要走，电动汽车本身有两大问题亟待解决，而且汽车电动化并不意味着零碳。由此可推测出，A项Total Electric Traffic：a Long Way to Go.（全电动交通：任重道远）最适合作本文标题。故选A。

201549. （2025•西安中学•一模）     Elon Musk has offered a prize of ＄100 m for the best carbon capture proposal.I can save his committee a lot of time.The money should go to Peter Wohlleben，whose book The Hidden Life of Trees was the most encouraging blockbuster of 2015.Wohlleben's idea is this：do nothing about trees.Stop fiddling with them，thinking that we can deal with climate change better than nature.If we fiddle，our Romes will burn.
    The Hidden Life of Trees argued that trees are social.It shows that they can be our saviors.But it's terribly hard to let ourselves be saved.We think we can be the authors of our salvation（拯救）.Of course，there are things we could and should be doing，but in terms of forestry practice，often what's billed as part of the solution is part of the problem.
    Anyone who has planted a tree in their garden knows that it has a far-reaching effect—it makes your garden cooler in summer and warmer in winter.Forests cool by transpiring（蒸发）.If there's no water，there's no cooling.Drought can kill trees fast，but trees have many ways of dealing with it，and Wohlleben sets them out.As a species，we have survived many climatic changes by changing our behavior—and that's how trees survive，too.Trees learn from their past harms and produce younger ones programmed with those lessons.They regulate their growth by changing the rate at which they drip（点滴）-feed them with sugar solution through root networks.
    Deciduous（落叶的） forests in particular remove greenhouse gases effectively as long as they live.Cut them down and burn them and you're releasing carbon dioxide not just from the wood，but also from the forest floor.Deciduous trees are not"harvest-ready"at200 years：they are teenagers.We must interrogate comforting expressions such as"renewable energy"，and learn the real cost of our toilet paper.
    If we don't learn to do nothing about trees，they will eventually be alone anyway—but without us.Wohlleben brilliantly and readably shows us how urgent and how hard it is to do nothing.

（1）What does Wohlleben suggest for carbon capture？
A.Fight climate change.
B.Leave trees alone.
C.Save the earth.
D.Change forestry species.
（2）How do trees survive the drought？
A.They slow their growth.
B.They lose all their leaves.
C.They stop absorbing water.
D.They get help from humans.
（3）What can we infer from the text？
A.We can cope with climate change successfully.
B.Trees can adjust their growth by themselves.
C.It is hard to stop releasing carbon dioxide.
D.It is urgent to regulate the growth of trees.
（4）What is the author's purpose in writing the text？
A.To illustrate the carbon capture system.
B.To give an account of the survival of trees.
C.To clarify a proposal for a reward.
D.To recommend a book.

203977. （2024•高新一中•高二下期末） Soot （煤） pollution is speeding up climate-driven melting in Antarctica，a new study suggests，raising questions about how to protect the delicate continent from the increasing number of humans who want to visit.
"It really makes us question，is our presence really needed？" says Alia Khan，one of the authors of the new study. "We have quite a large black carbon footprint in Antarctica，which is enhancing snow and ice melt."
   Black carbon is the leftover thing from burning plants or fossil fuels.Soot in Antarctica comes primarily from waste gases of cruise ships （游轮），vehicles and airplanes，although some pollution travels on the wind from other parts of the globe.The dark particles （微粒） coat white snow and absorb heat from the sun the way a black T-shirt does on a warm day.The blanket of dark bits speeds up melting that was already happening more quickly because of global warming.
   When snow and ice are uncovered，they reflect an enormous amount of sunlight before it can turn into heat. "These are the mirrors on our planet，" says Sonia Nagorski，a scientist at the University of Alaska Southeast. "When those mirrors are covered in a film of dark bits，they don't send back that much light and heat.That means more heat is trapped on Earth，speeding up melting and contributing to global warming."
   As a scientist who personally visits Antarctica every year，Khan saye is troubled by her own research results.On the one hand，she goes to Antarctica to collect crucial data about how quickly the snow and ice there are disappearing. "But then when we come to conclusions like this it really does make us think twice about how frequently we need to visit the continent，" she says， "and what kind of regulationould be placed on tourism as well." That could mean requiring that cruise ships and vehicles be electric，for example，or limiting the number of visitors each year.

（1）What is Khan's attitude towards human actions in Antarctica according to paragraph 2？
A．Angry and abusive.
B．Cold and uninterested.
C．Doubtful and anxious.
D．Admiring and delighted.
（2）What is the main cause of soot pollution in Antarctica？
A．The quick melting of ice and snow.
B．The emission from virous transport.
C．The remaining parts of burning plants.
D．The floating gases from other continents.
（3）What do we know from Nagorski？
A．The covered ice is less reflective.
B．The melting speed of ice is slower than before.
C．The dark blanket serves as a big mirror.
D．The sunlight gets increasingly stronger recently.
（4）Which is the most suitable title for the text？
A．What made our planet so polluted？
B．Who is to blame for air pollution？
C．Can electric vehicles save tourism？
D．Are we welcome to the South Pole？

202832. （2020•西工大附中•四模） At the first Olympic marathon in 1896，athletes ran a shorter course than today's 42.2-kilometer event．Even so，only the winner finished within three hours．However，runners have improved，and one expert predicted last year that the two-hour mark would be broken in 2028．
   On Oct 12，Eliud Kipchoge came in ahead of schedule - literally．The 34-year-old Olympic champion from Kenya became the first person to run a marathon in less than two hours．Clocking in at 1：59：40，Kipchoge pumped his chest and even sped up after crossing the finish line as he ran happily to his wife． "No one is limited．Thiows the positivity of sport，" Kipchoge told the BBC after the race in Vienna，Austria． "Together when we run，we can make it a beautiful world．"
   Apart from Kipchoge's strong willpower and outstanding physical condition，a few tricks of science and technology helped him reach this milestone in human athletic achievement．
   Hills and turns slow runners down，so Kipchoge's team picked the course in Vienna for its gentle curves （弯曲度）．
   The city's cool and dry weather was also important，said Wired．The magazine talked to exercise physiologists，who think the weather helped keep Kipchoge's body running more efficiently throughout the race．
   A special pair of shoes also played a big part．According to The New York Times，the shoes Kipchoge wore were designed to give a significant edge （优势） to anyone wearing them in a race．
   One other key to this breakthrough was Kipchoge's pacing strategy．He ran with a dream team of pacers， deployed by sports scientists．Five runners formed a V-shape ahead of Kipchoge，reducing drag （阻力），and two runners followed directly behind to push him forward．Kipchoge stayed in the center of the formation．The team rotated （轮换） members every five kilometers，and he stayed under a two-hour pace for almost the entire length of the race．There was also a pace car driving 15 meters in front of everyone，casting a laser （激光） line on the road to keep them on track．
   "Few world records today are technology free，" noted The Telegraph．Hard work and dedication are still the core （核心） of athletic achievement，but science and technology are helping modern athletes maximize their potential．

（1）Which of the following statements is true according to the first two paragraphs？
A．42.2-kilometer marathon first started in 1896．
B．Eliud Kipchoge is predicted to break the record in 2028．
C．Eliud Kipchoge won the Olympic champion at 1：59：40．
D．Eliud Kipchoge from Kenya set a new marathon record in less than two hour．
（2）What factor does not benefit Eliud Kipchoge in the challenge？
A．His strong willpower．
B．Physiologists' talk．
C．His extraordinary physical condition．
D．Special running shoes．
（3）What's the closest explanation of the underlined word？
A．follow
B．monitor
C．arrange
D．motivate
（4）What's the best title for the passage？
A．Running into record books．
B．How to maximize one's athletic potential．
C．Few world record today are technology free．
D．Eliud Kipchoge's outstanding sports achievements．

202833. （2020•西工大附中•四模） We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new，but a new study shows that we keep using our old devices （装置） well after they go out of style．That's bad news for the environment and our wallets-as these outdated devices consume much more energy than the newer ones that do the same things．
   To figure out how much power these devices are using，Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life from when its minerals are mined to when we stop using the device．This method provided a readout for how home energy use has evolved since the early 1990s．Devices were grouped by generation．Desktop computers，basic mobile phones，and box-set TVs defined 1992．Digital cameras arrived on the scene in 1997．And MP3 players，smart phones，and LCD TVs entered homes in 2002，before tablets and e-readerowed up in 2007．
   As we accumulated more devices，however，we didn't throw out our old ones． "The living-room television is replaced and gets planted in the kids' room，and suddenly one day，you have a TV in every room of the house，" said one researcher．The average number of electronic devices rose from four per household in 1992 to 13 in 2007．We're not just keeping these old devices -we continue to use them．According to the analysis of Babbitt's team，old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy，consumption and contribution to greenhouse gas emissions （排放） more than doubling during the 1992 to 2007 window．
   So what's the solution （解决方案）？The team's data only went up to 2007，but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function，such as a tablet for word processing and TV viewing．They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%．

（1）What does the author think of new devices？
A．They are environment-friendly．
B．They are no better than the old．
C．They cost more to use at home．
D．They go out of style quickly．
（2）Why did Babbitt's team conduct the research？
A．To reduce the cost of minerals．
B．To test the life cycle of a product．
C．To update consumers on new technology．
D．To find out electricity consumption of the devices．
（3）Which of the following uses the least energy？
A．The box-set TV．
B．The tablet．
C．The LCD TV．
D．The desktop computer．
（4）What does the text suggest people do about old electronic devices？
A．Stop using them．
B．Take them apart．
C．Upgrade them．
D．Recycle them．

202834. （2020•西工大附中•四模） Spring is coming，and it is time for those about to graduate to look for jobs．Competition is tough，so job seekers must carefully consider their personal choices．Whatever we are wearing，our family and friends may accept us，but the workplace may not．
   A high school newspaper editor said it is unfair for companies to discourage visible tattoos（文身）nose rings，or certain dress styles．It is true you can't judge a book by its cover，yet people do "cover" themselves in order to convey certain messages．What we wear，including tattoos and nose rings，is an expression of who we are．Just as people convey messages about themselves with their appearances，so do companies．Dress standards exist in the business world for a number of reasons，but the main concern is often about what customers accept．
   Others may say how to dress is a matter of personal freedom，but for businesses it is more about whether to make or lose money．Most employers do care about the personal appearances of their employees，because those people represent the companies to their customers．
   As a hiring manager I am paid to choose the people who would make the best impression on our customers．There are plenty of well-qualified candidates，so it is not wrong to reject someone who might disappoint my customers．Even though I am open-minded，I can't expect all our customers are．
   There is nobody to blame but yourself if your set of choices does not match that of your preferred employer．No company should have to change to satisfy a candidate simply because he or she is unwilling to respect its standards，as long as its standards are legal．

（1）Which of the following is the newspaper editor's opinion according to Paragraph 2？
A．People's appearances carry message about themselves．
B．Customers' choices influence dress standards in companies．
C．Candidates with tattoos or nose ringould be fairly treated．
D．Strange dress styleould not be encouraged in the workplace．
（2）What can be inferred from the text？
A．Candidates have to wear what companies prefer for an interview．
B．What to wear is not a matter of personal choice for companies．
C．Companies sometimes have to change to respect their candidates．
D．Hiring managers make the best impression on their candidates．
（3）Which of the following would be the best title for the text？
A．Employees Matter
B．Personal Choices Matter
C．Appearances Matter
D．Hiring Managers Matter
（4）The author's attitude towards strange dress styles in the workplace may best be described as       ．

203033. （2017•铁一中学•一模） ONE day I saw a TV advertisement．A couple - she in a black dress，he in a super-stylish shirt and tie - was enjoying a candlelit （烛光的） meal accompanied by romantic music．The location？Pizza Hut．I nearly choked on my tea．
   "What？!" I laughed to my Chinese friend． "Pizza Hut is trying to be all gourmet（美食的）and fashionable？!" My friend looked confused． "But Pizza Hut is fashionable，" she said． " You go there for a special meal．"
   In China，chain restaurants-especially the big multinational ones-are cool．Going to Starbucks，for example，is a status symbol．It not only says， " I'm rich enough to buy this overpriced coffee，" but also， "I'm cosmopolitan（见多识广的）enough to be part of globalization．"
   Where I come from in the UK，however，chains are neither fashionable nor gourmet．Chains are where you go on New Year's Day when nowhere are neither fashionable nor gourmet．Chains are where you go on New Year's Day when nowhere else is open，or when you are 5 years old and your parents can't stand hearing． "I'm hungry!" any longer．In my own case（with regards to McDonald's），a chain is where you are taken on your first "date"．Even at the age of 13，I knew to give the guy the "let's just be friends" phone call the next day．
   In the UK，independent cafes and restaurants are making a comeback on the fashion scene．Nowadays，a Londoner who says "let's meet for a coffee at Monmouth" （an independent café） is much cooler than one says "let's go to Starbucks"，Even if Monmouth's coffee is a little more expensive，there's a satisfaction in knowing your pounds aren't going straight to the big corporations．
   Of course，there are chain stores all over the UK；you can't go five minutes without spotting a Costa Coffee．But numbers do not add up to good taste．I do，however，have a confession．After moving to China I had moments when all the rice and Kung Pao Chicken became too much．I，too，have retreated to McDonald's．Even so，I would never describe my Big Mac as "haute cuisine．"
（1）Many Chinese people like to go to multinational chain restaurants because        ．
A．the restaurants give customers a taste of foreign culture
B．the restaurants offer different food and drinks from other restaurants
C．they believe that eating there will show their wealth and social status
D．these restaurants are perfect places for a romantic date
（2）Which of the following statements is TRUE？
A．The author has grown tired of Chinese food．
B．Branches of Monmouth's café can be found all over the UK．
C．Most independent stores are closed on New Year's Day in the Uk．
D．It is cool in the UK to take your first date to a chain restaurant．
（3）What does the underlined word " haute cuisine" in the last paragraph mean？
A．high-class cookery
B．expensive cookers
C．delicious food
D．a fashionable tradition
（4）What is the main point of the article？
A．The difference between Chinese food and the western food．
B．The comeback of independent cafes and restaurants in the UK
C．What makes chain restaurants gourmet and fashionable both in China and the UK．
D．The different attitudes towards chain restaurants of Chinese and British people．

203035. （2017•铁一中学•一模） The following passage is adapted from the writings of a Nobel Prize-winning scientist．
   Any scientist who is not a pretender will admit the important part that luck plays in scientific discovery．A colleague and I carried out an experiment in which little tissue fragments（组织碎片），which were very difficult to work with，were injected into mice of different DNA strains．If we had been more experienced，we would have injected only white blood cells （which would have been easier to handle） into the mice．We now know that if we had done this，we would not have made the discovery．Obviously，we were lucky，but our scientific training enabled us to recognize the significance of the accident．
   It might nevertheless seem as if luck plays a significant role in scientific discovery．However，I would like to challenge this view for the following reasons：we sometimes describe as "lucky" a person who wins a prize in a lottery at long odds；but if we describe such an event as luck，what word shall we use to describe the accidental discovery of a lottery ticket that turns out to be the winning one just on a park bench？
   The two cases are quite different．A person who buys a lottery ticket is putting himself or herself in the way of winning a prize．This individual has，so to speak，purchased candidacy（候选资格）for such a turn of events and all the rest is a matter of mathematical probabilities．So it is with scientists．A scientist is anyone who，by observations and experiments conducted，by the literature read，and even by the company kept，puts himself or herself in the way of making a discovery．These individuals，by deliberate action，have enormously enlarged their awareness-their candidacy for good fortune-and will now take into account evidence of a kind that a beginner or a casual observer would probably overlook or misinterpret．
   Nearly all successful scientists have emphasized the importance of preparedness of mind，and I want to emphasize that this preparedness of mind is worked for and paid for by a great deal of effort and reflection．If these efforts lead to a discovery，then I think it would be inappropriate to credit such a discovery to luck．
（1）The outcome of the experiment described in paragraph one suggests that
A．luck play an insignificant part in scientific discovery
B．the injection of only while blood cells allowed the two scientists to make their discovery
C．It was difficult to inject little tissue fragments into mice of different DNT strains
D．the scientists concerned in the experiment were able to benefit from luck
（2）The author uses the example of the lottery winner in order to suggest that
A．blind luck occurs more frequently than people realize
B．luck plays a more important part in most events than people realize
C．luck is not the correct term to use when referring to a significant scientific discovery
D．luck is the best word to be used to describe the accidental discovery in science
（3）The author implies that a scientist achieves " candidacy for good fortune" by
A．making careful and repeated mathematical calculations
B．depending on feelings rather than on scientific research
C．performing enough experiments to increase the statistical probability of success
D．obtaining knowledge that allows him or her to recognize important evidence
（4）The primary purpose of the passage is to
A．make a single definition of luck
B．show that scientists discover what they intend to find
C．compare scientific discovery to a lottery game
D．discuss the role of luck in science

203573. （2025•临潼区•高一上期末）     An adult African elephant consumes about 223 liters of water and 3，080 pounds of roots，grass and fruit daily.That's like having 634 cans of soda and 1，200 hamburgers every day.This keeps them moving thousands of miles across Africa each year.Elephants usually migrate between March and May.Females live in groups with their children，and quickly run out of the food supply.They hit the road in search of food.Male elephants live alone，so they don't use resources as quickly as the females.Instead，they migrate during their mating cycle.When the females pack their trunks，so do the males.
   During migration，elephants face short water supplies and extremely high temperatures.But people are their number-one problem.Poachers（偷猎者） kill 35，000 elephants each year for ivory.Many African farmers build fences（栅栏） to protect crops and cattle，which might block regular migration paths.Traffic roads affect elephant migration，too.During one study of 28 elephants in Central Africa，only one female crossed an unprotected road.
   Scientists，wildlife organizations and governments cooperate to find solutions for Africa's elephants."To unlock the secret of where elephants move and how they move，we place collars（项圈）with a satellite unit inside，"Dr.Michael Chase says.GPS collars help map which routes elephants use most so that countries can establish protected elephant passages.
    Locals come in as well.James Isiche，East Africa Director of the International Fund for Animal Welfare says，"We have got the community on our side by a project；they've agreed to partner with us to conserve elephants."The local community run wildlife parks to attract tourists."This project helps us take care of both the wildlife and our cows，""says Sikira，a tribal elder in Maasai，Kenya.Protecting elephant migration routes allows these gentle giants to survive.

（1）What can we learn about the elephants from paragraph 1？
A.They show an interest in hamburgers.
B.They move south to survive the cold.
C.They migrate for different reasons.
D.Females live shorter for food shortage.
（2）What is paragraph 2 of the text mainly about？
A.Results of poaching.
B.Reasons for killing elephants.
C.Difficulties in migrating.
D.Efforts to protect migration paths.
（3）Why are collars applied by scientists？
A.To discover the secret of migration.
B.To track elephants with technology.
C.To identify the population of elephants.
D.To explore a new route for migration.
（4）What is the best title for the text？
A.Say No to Ivory
B.A Journey in Africa
C.Ready for the Move
D.Technology in Migration

203658. （2024•师大附中•高二上期末） Transport is undergoing a massive transformation so it can meet society's demands for a low- carbon economy.Introducing electric vehicles （EV） and declining gasoline use are helping，but zero-carbon hydrogen can speed up both the transition （转变） and long-term decarbonization of transport.
   In the US，transportation produces the largest share of all greenhouse gas emissions （排放） in the economy at 29%，according to the Environmental Protection Agency.More than 90% of transport fuel is petrol based，but if more vehicles used hydrogen，emissions of this kind would plummet.
   However，hydrogen is not considered an ideal replacement for gasoline as an engine fuel for cars because it is harder to store safely.And while fuel cell electric vehicles （FCEVs） that turn hydrogen into electricity can compete with EV performance-and even out-compete them on range and refill time，extra energy is needed to produce the hydrogen needed for fuel.Also，finding investment for storage，pipelines and fuel stations is still a challenge for many nations.
   Currently，governments worldwide are backing green hydrogen projects to reduce greenhouse gas emissions in heavy industries like freight （货运），steel，and energy storage.But hydrogen transport will need rapid production methods to create the fuel needed for the world's road fleet.
   Thankfully，research is advancing all the time.Nanoscale （纳米级的） thin films are applied to improving the chemical process to rapidly harvest hydrogen from the seawater.The same technology has been successfully used in solar power devices with higher efficiency-to-cost rates.Since hydrogen is the most abundant element in the universe and as seawater makes up about 96% of all water on Earth，there is a virtually limitless supply.
   Even wastewater and solid waste can create green hydrogen.Researchers at Princeton University are using sunlight to separate hydrogen from industrial wastewater.Chemical plants that currently face high costs for cleaning wastewater could transform it into clean hydrogen supplies.

（1）What does the underlined word "plummet" mean in Paragraph 2？
A．Stop.
B．Decrease.
C．Continue.
D．Disappear.
（2）What is Paragraph 3 mainly about？
A．Ways of storing hydrogen safely.
B．Benefits of fuel cell electric vehicles.
C．Challenges of using hydrogen as car fuel.
D．Differences between gasoline and hydrogen.
（3）What makes it more efficient to get hydrogen from the ocean？
A．The application of solar power devices.
B．The method of identifying water elements.
C．The invention.of the water transport system.
D．The use of the nanoscale thin-film technology.

203806. （2024•周至四中•高一上期末） It was a village in India．The people were poor．However，they were not unhappy．After all，their forefathers had lived in the same way for centuries．
   Then one day，some visitors from the city arrived．They told the villagers there were some people elsewhere who liked to eat frog's legs．However，they did not have enough frogs of their own，and so they wanted to buy frogs from other places．
   This seemed like money for nothing．There were millions of frogs in the fields around，and they were no use to the villagers．All they had to do was catch them．Agreement was reached，and the children were sent into the fields to catch frogs．Every week a truck arrived to collect the catch and hand over the money．For the first time，the people were able to dream of a better future．But the dream didn't last long．
   The change was hardly noticed at first，but it seemed as if the crops were not doing so well．More worrying was that the children fell ill more often，and，there seemed to be more insects around lately．
   The villagers decided that they couldn't just wait to see the crops failing and the children getting weak．They would have to use the money earned to buy pesticides （杀虫剂） and medicines．Soon there was no money left．
   Then the people realized what was happening．It was the frog．They hadn't been useless．They had been doing an important job-eating insects．Now with so many frogs killed，the insects were increasing more rapidly．They were damaging the crops and spreading diseases．
   Now，the people are still poor．But in the evenings they sit in the village square and listen to sounds of insects and frogs．These sounds of the night now have a much deeper meaning．

203938. （2024•鄠邑二中•高一下期末）     Bumblebee （大黄蜂） populations have declined （下降） by 90 percent in the past 20 years.The decline of the bumblebees is highly concerning as they are significant for ecosystems.They pollinate （授粉） flowers and crops.If their populations were to continue to decline，crops would not be able to produce fruits and vegetables.Despite being small，they are important to nature's balance.
    And now，a new study published in the Frontiers in Bee Science has found that the rising heat caused by global warming might be a reason for the decrease in numbers across the globe. "The decline in populations and ranges of several species of bumblebees may be explained by issues of overheating of the nests，" Peter Kevan of the University of Guelph in Canada and lead author of the study said in a statement.
    Kevan and his colleagues decided to take a closer look at the facts relating to bumblebee populations across the world.Kevan and the colleagues looked at 180 years of literature on the species and found one common reason across all bumblebee species that they can survive in temperatures up to 36 degrees Celsius，but the perfect temperature for nests is between 28 to 32 degrees Celsius.They are unlikely to be able to adjust themselves to the extent that rising temperatures due to climate change require，the study reports.While individual bees may be able to deal with increased heat better than others，the study notes that if nests are too hot，the groups will not survive.
    "The effect of high nest temperatures has not been studied very much，which is surprising，" Kevan said.Similar studies have been done on honeybees （蜜蜂），another threatened yet highly important species.This suggests further that heat stress is a major factor in bees' overall decline.
    Although the studies led by Kevan have limitations，the potential effects for bumblebee health and conversation are large and long-term.

（1）What do we know about bumblebees from paragraph 1？
A.They have been extinct within decades in America.
B.Their populations have decreased a lot in the last two decades.
C.Americans are concerned about their living environment.
D.They tend to depend on flowers and crops to survive.
（2）How did Kevan and his coworkers carry out the study？
A.They raised bumblebees to observe them.
B.They focused on studying individual bumblebees.
C.They conducted experiments on bumblebees.
D.They studied literature on bumblebees.
（3）What is the author's attitude toward Kevan's studies？
A.Unclear.
B.Supportive.
C.Doubtful.
D.Uninterested.
（4）Which can be a suitable title for the text？
A.Big Results for Small Bumblebees
B.Bumblebees Protection Inspires Scientists
C.The Impact of Climate Change on Honeybees
D.Research Shows the Main Reason of Bumblebee Decline

204080. （2023•西安中学•高一上期末） If English means endless new words，difficult grammar and sometimes strange pronunciation，you are wrong.Haven't you noticed that you have become smarter since you started to learn a language？
   According to a new study by a British university，learning a second language can lead to an increase in your brain power.Researchers found that learning other languages changes grey matter.This is the area of the brain which processes information.It is similar to the way that exercise builds muscles.
   The study also found the effect is greater when the younger people learn a second language.A team led by Dr.Andrea Mechelli，from London University，took a group of Britain people who only spoke English.They were compared with a group of "early bilinguals" who had learnt a second language before the age of five，as well as a number of later learners.
   Scanowed that grey matter density in the brain was greater in bilinguals than in people without a second language.But the longer a person waited before mastering a new language，the smaller the difference was.
   "Our findings suggest that the structure of the brain is changed by the experience of learning a second language，" said the scientists.It means that the change itself increases the ability to learn.
   Professor Dylan Vaughan Jones of the University of Wales has researched the link between bilingualism and math skill. "Having two languages gives you two windows on the world and makes the brain more flexible，" he said. "You are actually going beyond language and have a better understanding of different ideas."
   The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of 2 and 34.Reading，writing and comprehension were all tested.The resultowed that the younger they started to learn，the better. "Studying a language means you get an entrance to another world，" explained the scientists.

（1）The main subject talked about in this passage is       .
A．science on learning a second language
B．man's ability of learning a second language
C．language can help brain power
D．language learning and math study
（2）In the second paragraph，the writer mentions "exercise" in order to       .
A．say language is also a kind of physical labor
B．prove that one needs more practice when he/she is learning a language
C．show the importance of using the language when you learn the language
D．make people believe language learning helps grey matter work well
（3）In the last two paragraphs，the author wants to tell us that       .
A．learning a second language is the same as studying math
B．early learning of a second language helps you a great deal in study other subjects
C．Italian is the best choice for you as a second language
D．we'd better choose the ages between 2 and 34 to learn a second language

201578. （2025•长安区•一模）     Will artificial intelligence （AI） replace my job？This is a question that many people think about these days.At present，the application of AI robotics in professional fields，as well as ChatGPT's abilities to write essays，solve complex problems and more，have heightened moral concerns.
    Some people see AI as the ultimate cure for society's most fundamental problems，while others fear that AI will overtake human intelligence.These two views are based on the assumption that AI is better and smarter than humanity and may ultimately replace human decision-making.But given the fact that technology is the product of human civilization，the challenge from AI is something we have created for ourselves as we keep pushing our own boundaries.In other words，AI's progress，functions and future direction are all determined by the human brain.
    Before AI becomes a threat to humanity，the international community should reach an agreement on the role it is to play.More importantly，related laws and regulations must ensure that AI will benefit society and prevent it from threatening human life.Robots，for example，are believed to develop emotional intelligence sometime，which enables them to recognize，understand and express emotions in a way that is similar to humans，but we must avoid AI copying human emotions.Without legal restrictions，AI may become a social disaster.
    The AI-driven new industrial revolution（革命） is irreversible.This，like previous ones，which introduced changes that had been unimaginable before，will certainly affect human employment.But it always turned out humanity was able to adapt to each industrial revolution and create new forms of employment.Therefore，it's unnecessary to worry AI will replace our jobs.While technology advances at a rapid pace，what we need to do is to welcome the AI era rather than block its unfolding for fear of the unknown.

（1）Why are some people concerned about AI？
A．It has been applied widely.
B．It has led to social problems.
C．It may outsmart humans.
D．It is the product of humanity.
（2）How can we prevent AI's potential threat？
A．By stirring emotions.
B．By setting restrictions.
C．By blocking functions.
D．By changing regulations.
（3）What does the underlined word "irreversible" in the last paragraph mean？
A．Undesirable.
B．Unbelievable.
C．Unpredictable.
D．Unavoidable.
（4）What does the writer suggest readers do with the coming of the AI era？
A．Deal with it positively.
B．Accept it passively.
C．Respond to it randomly.
D．Defend it unconditionally.

204106. （2023•西安中学•高二上期末） I walked along the sidewalk that borders the west side of Central Park this morning，wondering at itape：Hexagonal（六边形的） paving stones underneath my feet were bordered by brickwork，with a tidy stone wall running alongside.Just past the wall lay the park itself，where delicate branches of leafless trees reached to the blue sky，and sparrows emerged from trees.
   The contrast between the straight-lined，orderly，man-made sidewalk and the complex diversity of nature just beyond its border made me think about the differences between natural creation and man's creation.
   The world holds many examples of circles：the moon，grapes，drops of water and the center of flowers.Triangles（三角形） are readily evident，too.There are kitty cat noses and ears，mountain peaks and river deltas.
   But what about the most common shape in the man-made world，the rectangle（矩形）？I searched my brain for natural equals.Though I thought and thought，I came up with only two：teeth and salt crystals.That surprised me.Do we prefer rectangles simply because it's easier to plan and build with blocks and straight lines？Or does it have something to do with the idea that humans tend to assume life is supposed to be linear？I don't know.
   There are bent lines everywhere.As I look at the beauty of，a tree in winter，with its branches reaching skyward in a seemingly untidy but obviously planned pattern，I can apprehend something of what that means.
   Our world isn't always tidy and predictable in the way that I want it to be.There are twists and turns in my life that I can't foresee or predict.That doesn't mean branching off in unexpected directions is bad or wrong.It means that when I find myself in each new place，I need to continue growing and reaching upward.

（1）How did the author feel about the sidewalk'ape？
A．disappointed.
B．surprised.
C．worried.
D．pleased.
（2）What is the author' s attitude to the variouapes mentioned in the text？
A．negative.
B．cautious.
C．unconcerned.
D．objective.
（3）Which can explain the underlined word "apprehend" in paragraph 5？
A．create.
B．imagine.
C．understand.
D．arrange.
（4）What may the author agree with？
A．People should live in a complex world.
B．Triangles are the most common in nature.
C．Natural creation and man's creation should be balanced.
D．We should move forward in the face of uncertainties.

204108. （2023•西安中学•高二上期末） Climate change disproportionately affects the world's most vulnerable people，particularly poor rural communities that depend on the land for their livelihoods and coastal populations throughout the tropics.We have already seen a chain of tough suffering that results from extreme weather events，such as hurricanes，floods，droughts，wildfires，and more.
   For remedies，advocates and politicians have tended to look toward cuts in fossil-fuel use or technologies to capture carbon before it enters the atmosphere—both of which are crucial.But this focus has overshadowed the most powerful and cost-efficient carbon capture technology in the world.Recent research confirms that forests are absolutely essential in reducing climate change，thanks to their ability to absorb and isolate carbon.In fact，natural climate solutions such as conservation and restoration of forests，along with improvements in land management，can help us achieve 37 percent of our climate target of limiting warming to a maximum of two degrees Celsius above preindustrial levels，even though they currently receive only 2.5 percent of public climate financing.
   Forests' power to store carbon dioxide is staggering：one tree can store an average of about 48 pounds in one year.Intact（完整的）forests could take in the CO₂ emissions of some entire countries.
   For this reason，policymakers and business leaders must create and enforce policies to prevent deforestation，foster，reforestation of degraded land，and promote the sustainable management of standing forests in the fight against climate change.Protecting the world's forests ensures they can keep performing essential functions such as producing oxygen，filtering water and supporting biodiversity.Not only does the world's entire population depend on forests to provide clean air，clean water，oxygen and medicines，but 1.6 billion people also rely on them directly for their livelihoods.
   Unfortunately，a huge amount of forest continues to be converted into agricultural land to produce a handful of resource-intensive commodities - despite zero-deforestation commitments from companies and governments.So now is the time to increase forest protection and restoration.This action will also address a number of other pressing global issues.For example，in less developed，rural areas - especially in the tropics - community-based forest-management programs can forge pathways out of poverty.In the Peten region of Guatemala，for instance，community-managed forests boasted a near-zero deforestation rate from 2000 through 2013，as compared with 12 percent in nearby protected areas and buffer（缓冲）zones.These communities have built low-impact，sustainable forest-based businesses that have stimulated the economy of the region enough to fund the creation of local schools and health services.Their success is especially noticeable in a location where，outside these community-managed zones，deforestation rates have increased 20-fold.

（1）Which of the following statements about natural climate solutions is true according to the passage？
A．They are the only effective strategies available to address the climate change.
B．They pale in comparison with the reduction in fossil-fuel use or technologies.
C．They can and should play a more important role in cutting carbon emissions.
D．They manage to limit warming to two degrees Celsius above pre-industrial levels.
（2）The word "staggering" （Paragraph 3）is closest in meaning to "        ".
A．documented
B．incredible
C．unsteady
D．negligible
（3）Which of the following statements is the author most likely to agree with？
A．The policies to prevent deforestation have borne fruit.
B．Developed countries are hit the hardest by climate change.
C．Economic growth contributes a lot to reducing deforestation.
D．Some governments fail to keep their promises to preserve forests.
（4）What does the passage mainly talk about？
A．Keeping forests undamaged can go a long way toward saving the planet.
B．A high-tech climate fix is required to dramatically lessen global warming.
C．Governmentould work together with businesses to stop deforestation.
D．Sustainable management of forests is crucial in powering regional development.
