    "Chen is a pretty and charming girl，who never easily gives up，" said Quan.
    "As athletes，we both have the desire to win.It's a lie if we say we don't.That is why we both work extremely hard and fight for the same goal.We never stop pushing ourselves，" said Chen. "But this is a very positive competition.Such a life，as a top national team diver，is a very special and unforgettable experience.She is the best encouragement to me，and that's why I'm growing."
    But in Quan's eyes，Chen is the more hardworking one of the two." She always tries her best at training and competition.I'm not as hardworking ae is，" Quan added.
    "The Asian Games gold is just another decoration of my career，and it's just a small test ahead of the Paris Olympics.There are still problems we need to fix，" said Chen.
    "I hope my partner always has a champion's heart to face future competitions and all of the challenges ahead."

Health Benefits of Rollerblading（滑旱冰） Rollerblading is a popular sport nowadays.（1）       .These activities require a combination of balance，coordination，and physical fitness，making the sport an excellent form of cardiovascular exercise（有氧运动）.Here are some health benefits of rollerblading according to doctors.
Keep bones healthy
    With age，bones tend to lose their definition and density.Rollerblading is a form of exercise that can reduce the risk of osteoporosis（骨质疏松）. "Unlike running and other high-impact activities，rollerblading reduces the stress on your knees and ankles.（2）       ."Says Florence Comite，founder of the Comite Center for Precision Medicine & Health.
（3）
    Rollerblading requires use of an individual's core muscles to keep them upright and balanced."Rollerblading uses a greater side-to-side striding motion，"Dr.Comite says."It requires using your arms and balancing which involves your core muscle to stabilize your spine."A recent research also found that exercises such as rollerblading and roller-skating have been shown to improve balance among older adults.
Burn calories
    Not only is rollerblading fun，but it can also burn a lot of calories in a short period of time.According to Harvard Medical School，an individual can burn upwards of 600 calories per hour when rollerblading.（4）       .
Boost mood
    （5）       .That's because the body will release endorphins，a biochemical that helps enhance your mood.Plus，if you love the feeling of rollerblading，the benefits may be even better.A 2017 review published in Brain Plasticity indicates that enjoying your workout can make its lift to your mood last up to a day after you've finished exercising.

A.Improve balance
B.Strengthen arm muscles
C.Usually the body will release chemicals
D.After rollerblading，it's probable that you'll feel great
E.So it's a suitable exercise for people with bone problems
F.Therefore，rollerblading can be a great choice if you want to lose weight
G.Participants can engage in activities such as speed skating and freestyle tricks

204591. （2023•高新一中•高二下期末） The 2022 World Cup has come to an end.Let's review some facts about the hi-tech turf （草皮） that Qatar had spent much of its energy on.
   Qatar，a desert nation，had three main challenges：water，air and light.It got almost every condition going against it.The water used to irrigate （灌溉） the grass is low quality，mainly treated seawater.Because of the desert sun，Qatar's stadiums were built for maximum shade—great for preventing heatstroke，but less ideal for photosynthesis （光合作用）.Inside the nearly-closed stadiums，there's very little air movement.
   Qatar identified pitch （球场） quality as a particular issue and set up the Aspire Sport Turf Research and Development Centre to find the best types of grass for use in the harsh climate，testing 24 different varieties.Eventually，Atlas Turf's grass was chosen as much for its appearance as its tolerance for the tough conditions Qatar faces.
   The following pictureow some tech facts about the turf，which ensures a consistent and durable surface for the players in all weather conditions.

205227. （2021•长安区一中•高二上期末） Captured（捕获的）carbon dioxide（CO₂）could be used to extract（提炼）useful metals（金属）from recycled technology such as smartphone batteries rather than just being buried underground.The technique could help make it more economical to capture the greenhouse gas before it enters the atmosphere.
   "If you also extract metals by filling CO₂，you add value to a process that is known to be costly，" says Julien Leclaire at the University of Lyon，France.
   CO₂ is the main cause of modern climate change，so many people have attempted to develop technologies to capture it when it comes from power plants and other major sources.The gas can then be stored underground.The problem is that such carbon capture and storage（CCS）is expensive."No one wants to pay the price for it，" says Leclaire.
   To make CCS more appealing，Leclaire's team has found a use for the gas.
   His team collected CO₂ from a car gas，cooledit，then pumped it into a mix of chemicals.
   The CO₂combined with the mix to make many molecules（分子）of variouapes and sizes.
   The team found that this process could sort out mixtures of metals，because one metal would dissolve（溶解）in the liquid while another would form a solid.In a series of experiments，they successfully separated three kinds of metals-all of which are used in batteries，smart phones and computers.
   If the process can be widely used，it could be a more environmentally friendly way to recycle batteries and other electrical equipment，says Leclaire.This is normally done using highly reactive chemicals，which are potentially polluting.Replacing them with CO₂ should lead to a much lower environmental pollution，he says.
   Other researchers and companies are trying to change captured CO₂ into useful materials like plastics，which are normally produced from petrol，but this is chemically difficult.Leclaire says his approach is more inline with how CO₂ behaves naturally."Instead of copying what we know how to do better and cheaper with oil，let's find things you can only do with CO₂，" he says.

（1）What can we learn from the first paragraph？
A．Extracting useful metals from recycled technology is widely used now.
B．Useful metals in the atmosphere are used to make smart phone batteries.
C．Abandoned smart phone batteries may have been buried underground before.
D．The greenhouse gas CO₂ could be cleaned up after entering the atmosphere.
（2）Why are many people attempting to capture CO₂？
A．CO₂ is the main cause of modern climate change.
B．CO₂ can be used to recycle many resources.
C．Captured CO₂ can be changed to useful gas.
D．CO₂ is harmful to people's health.
（3）What benefit could Leclaire's team's approach bring？
A．It could end the use of plastics.
B．It could reduce environmental pollution.
C．It could make more metals available to humans.
D．It could help reduce the cost of battery production.
（4）What is the best title for the text？
A．The Ways to Make Smart phone Batteries
B．The Reason for Capturing Greenhouse Gas
C．Collecting CO₂ Is Starting to Make New Progress
D．Captured CO₂ Could Be Used to Help Recycle Useful Metals

202920. （2018•交大附中•六模） Human remains of ancient settlements will be reburied and lost to science under a law that threatens research into the history of humans in Britain，a group of leading archeologists says．In a letter addressed to the justice secretary，Ken Clarke，40 archaeologists write of their "deep and widespread concern" about the issue．It centers on the law introduced by the Ministry of Justice in 2008 which requires all human remains unearthed in England and Wales to be reburied within two years，regardless of their age．The decision means scientists have too little time to study bones and other human remains of national and cultural significance．
   "Your current requirement that all archaeologically unearthed human remainould be reburied，whether after a standard period of two years or a further special extension，is contrary to basic principles of archaeological and scientific research and of museum practice，" they write．
   The law applies to any pieces of bone uncovered at around 400 dig sites，including the remains of 60 or so bodies found at Stonehenge in 2008 that date back to 3，000 BC．Archaeologists have been granted a temporary extension to give them more time，but eventually the bones will have to be returned to the ground．
   The arrangements may result in the waste of future discoveries at sites such as Happisburgh in Norfolk，where digging is continuing after the discovery of stone tools made by early humans 950，000 years ago．If human remains were found at Happisburgh，they would be the oldest in northern Europe and the first indication of what this species was．Under the current practice of the law those remains would have to be reburied and effectively destroyed．
   Before 2008，guidelines allowed for the proper preservation and study of bones of sufficient age and historical interest，while the Burial Act 1857 applied to more recent remains．The Ministry of Justice assured archaeologists two years ago that the law was temporary，but has so far failed to revise it．
Mike Parker Pearson，an archaeologist at Sheffield University，said： "Archaeologists have been extremely patient because we were led to believe the ministry was sorting out this problem，but we feel that we cannot wait any longer．"
   The ministry has no guidelines on where or how remainould be reburied，or on what recordould be kept．

（1）According to the passage，scientists are unhappy with the law mainly because        ．
A．it is only a temporary measure on the human remains．
B．it is unreasonable and thus destructive to scientific research．
C．it was introduced by the government without their knowledge．
D．it is unclear about where and how to rebury human remains．
（2）We can learn from the passage that        ．
A．Temporary extension of two years will guarantee scientists enough time．
B．Human remains of the oldest species were dug out at Happisburgh．
C．Human remains will have to be reburied despite the extension of time．
D．Scientists have been warned that the law can hardly be changed．
（3）What can be inferred about the British law governing human remains？
A．The Ministry of Justice did not intend it to protect human remains．
B．The Burial Act 1857 only applied to remains uncovered before 1857．
C．The law on human remains hasn't changed in recent decades．
D．The Ministry of Justice has not done enough about the law．
（4）Which of the following might be the best title of the passage？
A．New discoverieould be reburied，the government demands．
B．Research time should be extended，scientists require．
C．Law on human remains needs thorough discussion，authorities say．
D．Law could bury ancient secrets for ever，archeologists warn．

202282. （2022•西工大附中•七模） Innovation has pretty much finished with car tires （轮胎） right，I mean，what's left to change？How about the whole "air" part？
   Michelin Company's attempt to tackle tire rubbish around the world witnessed them roll out puncture-proof "airless" tires，which they say should help reduce the 18% of all world tires that are abandoned early due to punctures （轮胎漏气）.Deserted tires are a huge worldwide waste problem—the U.S.produces 260 million abandoned tires per year，many of which end up in landfills or on the sides of the freeway where they release harmful gases and micro-plastic pollutants as they break down.
   Michelin Company's Unique Puncture Proof Tire System or "UPTIS" is designed using 46% recycled material，and made from a plastic matrix （母体） mixed with glass fibers that provide a flexible outer layer with a strong inner one. "The truly distinctive structure of the Michelin UPTIS prototype（原型），or its "strangeness" as we have often heard it called，really attracted the eye of many visitors and left a lasting impression on them，" stated Cyrille Roget，Michelin Group Technical and Scientific Communications Director. "It was an unusual experience for us，and our greatest satisfaction came at the end of the demonstration when our passengers，who were undoubtedly a little alert（警觉）at first，said they felt no difference compared with conventional tires."
   Michelin Company believes airless tires will improve everyone's lives.Maintenance （保养） costs for company's vehicle fleets will be less expensive，and inexperienced car owners won't accidentally ruin their rubbers when driving them because they are over-or under-inflated（充气）.Although they are still in development stage and using at a large scale within years is unlikely to be available，Michelin Company is not in the least doubtful about their tires' future.

（1）Why does the author ask questions in the first paragraph？
A．To explain a strange phenomenon.
B．To clarify a difficult concept.
C．To present a well-known fact.
D．To introduce a new topic.
（2）What is the main idea of the second paragraph？
A．The new tire runs more smoothly.
B．The world greatly needs airless tires.
C．Traditional tires threaten the environment.
D．Michelin Company battles the issue of wasted tires.
（3）What do we know about "UPTIS"？
A．Its structure distances visitors.
B．It only uses recycled materials.
C．It combines plastic and glass fibers.
D．Its comfortableness beats ordinary tires.
（4）What's Michelin Company's attitude towards their new tires？
A．Tolerant.

202281. （2022•西工大附中•七模） It is not easy to excite New Yorkers or keep them going easy on things around.This is one reason why actors and other famous people move to the city.They can live quieter lives and escape the paparazzi photographers who would follow them in Hollywood.

202939. （2017•师大附中•十一模） When students and parents are asked to rate subjects according to their importance，the arts are unavoidably at the bottom of the list．Music is nice ，people seem to say ，but not important．Too often it is viewed as entertainment，but certainly not an education priority（优先）．This view iortsighted．In fact，music education is beneficial and important for all students
   Music tells us who we are．Because music is an expression of the beings who create it，it reflects their thinking and values，as well as the social environment it came from．Rock music represents a lifestyle just as surely as does a Schubert song．The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions．Music expresses our character and values．It gives us identity as a society．
   Music provides a kind of perception（视角）that cannot be acquired any other way．Science can explain how the sun rises and sets．The arts explore the emotive（情感的）meaning of the same phenomenon．We need every possible way to discover and respond to our world for one simple but powerful reason：No one way can get it all．
   The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols．They are ways we human beings "talk" to each other．They are the language of civilization through which we express our fears，our curiosities our hungers，our discoveries，our hopes．The arts are ways we give form to our ideas and imagination so that they can be shared with others．When we do not give children access to an important way of expressing themselves such as music，we take away from them the meanings that music expresses．
   So music education is far more necessary than people seem to realize．

（1）According to paragraph 1，students       ．
A．regard music as a way of entertainment
B．disagree with their parents on education
C．view music as an overlooked subject
D．prefer the arts to science
（2）In Paragraph 2，the author uses jazz as an example to       ．
A．compare it with rock music
B．show music identifies a society
C．introduce American musical traditions
D．prove music influences people's lifestyles
（3）According to the passage ，the arts and science       ．
A．approach the world from different angles
B．explore different phenomena of the world
C．express people's feeling in different ways
D．explain what it means to be human differently
（4）What is the main idea of the passage？
A．Music education deserves more attention．
B．Music should be of top education priority．
C．Music is an effective communication tool．
D．Music education makes students more imaginative．

202958. （2017•师大附中•七模） Dreams can be familiar and strange，fantastical or boring，but some dreams might be connected to the mental processes that help us learn．In a recent study，scientists found a connection between nap-time dreams and better memory in people who were learning a new skill．
   In the study，99 college students between the ages of 18 and 30 each spent an hour on a computer，trying to get through a virtual maze（迷宫）．The maze was a different place each time they tired-making it even more difficult．They were also told to find a particular picture of a tree and remember where it was．
   For the first 90 minutes of a five-hour break，half of the participants stayed awake and an half were told to take a short nap．Participants who stayed awake were asked to describe their thoughts．Participants who took a nap were asked about their dreams after sleeping-and they were awakened within a minute of sleeping to describe their dreams．Stickgold，a neuroscientist（神经科学家），wanted to know what people were dreaming about when their eyes weren't moving during sleep．
   Four of the 50 people who slept said their dreams were connected to the maze．Some dreamed about the music that had been playing when they were working；Others said they dreamed about seeing people in the maze．When these four people tried the computer maze again，they were able to find the tree faster than before their naps．
   Stickgold suggests the dream itself doesn't help a person learn-it's the other way around．He suspects that the dream was caused by the brain processes associated with learning．
   All four of the people who dreamed about the task had done poorly the first time，which makes Stickgold wonder if the dreamow up when a person finds a new task particularly difficult．People who had other dreams，or people who didn't take a nap，didn't show the same improvement．

（1）After having a short nap，participants of the experiment were asked to       ．
A．stay in a．different place in the maze．
B．design a virtual maze which is difficult to get through．
C．try to remember something about their dreams
D．get through a virtual maze on a computer from the same place
（2）What can we learn from the text？
A．Participants who took a nap were required to express their thoughts．
B．Some dreams may encourage people to invent something new．
C．Participants who dreamed about films could finish the task more easily．
D．Participants whose dreams had something to do with the maze could find the tree faster．
（3）According to Stickgold，       ．
A．every person may dream about what they learned
B．people's brain processes may still be connected with their learning in their dreams
C．once people's eyes stop moving，they are sure to dream about something
D．no matter how fantastical or boring，dreams are connected with people's life
（4）What is the best title for this text？
A．Dreams Are Strange

202244. （2022•临潼区•二模） The World Health Organization says the widespread use of sugar in food products and drinks is a major concern in many areas.So WHO officials are calling on governments to require taxes on sugary drinks in an effort to limit their usage and popularity.The officials believe the taxes also would reduce the risk of health problems resulting from obesity.
   Obesity is a condition in which the body stores large，unhealthy amounts of fat.Obese individuals are considered overweight.A new report says that in 2014 more than one-third of the adults in the world were overweight，and 500 million were considered obese.The United Nations agency estimates that in 2015，42 million children under age 5 were either overweight or obese.It says that number represents an increase of about 11 million during the past 15 years.Almost half of these boys and girls live in Asia and one-fourth in Africa.
   The U.N.agency blames unhealthy diets for a rise in diabetes cases.There are 422 million cases of the disease worldwide.Who says 1.5 million people die from it every year.It says the use of sugar in food products，like sugary drinks，is a major reason for the increase in rates of obesity and diabetes.
   Temo waqanivalu is with the agency's Department for the Prevention on Non-Communicable Diseases：He told VOA that taxing sugary drinks would reduce consumption and save lives.Waqanivalu noted that Mexico enacted a law of a 10 percent tax on sugary drinks in 2014.He said by the end of the year，there was a 6 percent drop in the consumption of such drinks.Among poor people，the number of people who consumed sugary drinks dropped by 17 percent.

202226. （2022•临潼区•一模） You probably don't think of scientific or medical instruments as the kind of instruments that actually make music.But now researchers have built a scientific instrument specifically designed to detect counterfeit（伪造的）medications through sound.
   The World Health Organization estimates about 10 percent of the medications in low and middle-income countries are fakes.Sometimes，dangerous ones.So the idea here is to fill the tube with a sample that's known to be safe.Then compare it to a bottle you're not so sure about.
   "If you get the same pitch（音高）out of those two samples，it's very good evidence that they're probably the same material，and the suspect substance is a safe drug to take.But if you get a different pitch out of the two samples，that's absolute proof that those two samples are chemically different.And that shows you there's something wrong with the sample you were given and you probably shouldn't take it."
   The instrument is designed to test only liquid samples for now.And while the human ear is sensitive enough to hear the difference between samples of air and water，the difference between a real and a counterfeit drug might be imperceptible to our ears.So Grover built a free website where users can upload recordings of the instrument，from their smartphone or computer，and analyze the hertz.Then repeat it with the suspect sample.
   ...in the hope of inspiring people around the world to build these things themselves. "I can literally make one of these out of junk in your garage in about five minutes probably.The hardest thing to come by is tubing.We've made them out of bent copper tubing like you get out of a radiator.Just junk，lying around.It's remarkable how easy they are to make.My dream would be to have the instructions for making them and using them shared as widely as possible."
   It is，admittedly，a pretty convincing pitch.

（1）What's the passage mainly about？
A．A scientific instrument.
B．A pretty convincing tube.
C．A suspect sample.
D．A dangerous instrument.
（2）What's the function of the instrument according to the passage？
A．To give the buyer more drugs as a gift.
B．To make the wonderful music.
C．To carry the liquid.
D．To test fake medications through sound.
（3）Where can you get the material to build this kind of scientific instrument？
A．The junk in the garage.
B．The junk in the drugstore.
C．The junk in the supermarket.
D．The junk in the factory.
（4）What can we learn about the instrument from the passage？
A．Everyone can make it easily.
B．It can play the music you like.
C．There is a long way to go.
D．It is widely used to test medicine.

202635. （2020•西安中学•四模） In the early days of sea travel，seamen on long voyages lived exclusively on salted meat and biscuits．Many of them died of scurvy （坏血病），a disease of the blood which causes swollen gums （牙龈），livid white spots on the flesh and general exhaustion．On one occasion，in 1535，an English ship arrived in Newfoundland with its crew desperately ill．The men's lives were saved by Iroquois Indians who gave them vegetable leaves to eat．Gradually it came to be realized that scurvy was caused by some lack in the sailors' diet and Captain Cook，on his long voyages of discovery to Australia and New Zealand，established the fact that scurvy could be prevented by the supply of fresh fruit for the sailors．
   Nowadays it is understood that a diet which contains nothing harmful may yet result in serious disease if certain important elements are missing．These elements are called "vitamins"．Quite a number of such substances are known and they are given letters to identify them，A，B，C，D，and so on．Different diseases are associated with shortages of particular vitamins．Even a slight lack of Vitamin C，for example，the vitamin most plentiful in fresh fruit and vegetables，is thought to increase significantly our susceptibility （敏感度） to colds and influenza．
   The vitamins necessary for a healthy body are normally supplied by a good mixed diet，including a variety of fruit and green vegetables．It is only when people try to live on a very restricted diet，say during extended periods of religious fasting （斋戒），or when trying to lose weight，that it is necessary to make special supply to make up for the missing vitamins．

（1）Scurvy is a disease that is caused by       ．
A．salted meat and biscuits
B．exhaustion
C．lack of some essential substances
D．need of fresh vegetables and fruits
（2）To avoid such disease as scurvy，it's better for us       ．
A．not to eat much salted meat
B．to supply our diet with various vitamin pills
C．to have more fresh fruit and vegetables
D．to develop a good dietary habit
（3）Based on the passage we can safely conclude that if our diet is not comprehensive enough，       ．
A．vitamin pills are of no use
B．nutritious food might be unhealthy
C．vegetable leaves can be a good treatment
D．religious fasting may help out a lot
（4）Which of the following sentences best expresses the main idea of the passage？
A．Shortages of Vitamin C may cause serious diseases．
B．Fresh fruit and green vegetables contain enough nutrition that is necessary for a healthy body．
C．Vitamins play a vitally important role in people's health．
D．A good mixed diet normally supplies sufficient vitamins for us．

205137. （2022•鄠邑区•高一下期末） A scientist locked himself in a small air-tight plastic tent with 200 plants to see if they could change CO₂ into oxygen （氧气） fast enough to keep him alive.
   Kurtis Baute locked himself in a 3 m by 3 m tent in his brother's backyard in British Columbia，Canada.He hoped to find out if by surrounding himself with plants，the CO₂ he breathed out could be changed into oxygen to allow him to survive in the locked tent for at least three days.
   Unfortunately，he had to give up the experiment after only 15 hours，as CO₂ levels reached a dangerous point where he risked suffering brain damage. "I could probably survive in the tent for three days，" Baute wrote on his website. "But my goal is not to just 'not die'.My goal is to end this project without developing brain damage or just generally causing lasting harm to my body.But as it turns out，that's exactly what he risked as the 200 plants he took with him into the tent couldn't meet his needs.Clearly，a cloudy sky prevented them from receiving all the sunlight they needed to perform photosynthesis （光合作用），so they couldn't recycle CO₂ fast enough.
   "Plants are great at taking in CO₂ and they love it.Since it wasn't a bright and sunny day，they weren't getting the light they needed，which meant CO₂ just kept rising.I had to give up the experiment as that continued." the young experimenter said.15 hours into the experiment，Baute reached the set danger point and then ended this experiment.Still，he called the experiment a "huge success" as his main goal was actually the terrible effects of climate change and CO₂ emissions.
   "The conclusion about my experiment is that if CO₂ is too high，I'll escape，which is just everyday experiences for many people on this planet.Everyone deserves clean air，but not everyone has it，" he wrote.

（1）Why did Kurtis Baute stay in the tent for only 15 hours？
A．The tent is too small for him to stay too long.
B．The environment in the tent is dangerous for him.
C．CO₂ in the tent couldn't be changed into oxygen.
D．He couldn't survive in the locked tent any longer.
（2）What made it hard for the 200 plants to satisfy Kurtis Baute's needs？
A．His health condition.
B．His wrong decision.
C．Too much CO₂.
D．The cloudy weather.
（3）What does Kurtis think of the result of the experiment？
A．Disappointing.
B．Surprising.
C．Satisfying.
D．Interesting.
（4）What may be the best title for the text？
A．A test to show the importance of clean air.
B．Surviving in the tent.
C．The set danger point.
D．Making people know the use of plants.

205695. （2018•西安中学•高二下期末） Summer heat can be dangerous，and heat leads to tragedy far too often．According to kidsandcars.org，an average of 37 young children per year die of car heat in the US，when they are accidentally left in a hot vehicle．
   For Bishop Curry，a fifth grader from McKinney，Texas，one such incident hit close to home．A six-month-old baby from his neighborhood died after hours in a hot car．After hearing about her death，Curry decided that something needed to be done．Young Curry，who turned 11 this year，has always had a knack for inventing things，and he drew up a sketch（草图） of a device he called "Oasis．"
   The device would attach to car seats and watch the temperature inside the car．If it reached a certain temperature in the car，and the device sensed a child in the car seat，it would begin to circulate cool air．Curry also designs the device using GPS and Wi-Fi technology，which would alarm the child's parents and，if there was no response from them，the police．
   Curry's father believes that the invention has potential． "The cool thing about Bishop's thinking is none of this technology is new，" he said． "We feel like the way he's thinking and combining all these technologies will get to production faster．" His father even introduced the device to Toyota，where he works as an engineer．The company was so impressed that they sent Curry and his father to a car safety conference in Michigan．
   In January，Curry's father launched a campaign for the invention．They hope to raise money to finalize the patent，build models，and find a manufacturer．Their goal was＄20，000，but so many people believed in Oasis' potential that they have raised more than twice that--over＄46，000．

A．It would inform the parents or even the police．
B．It would pump out the hot air in the car．
C．It would sound the alarm attached to the car．
D．It would get the window open to save the child．
（3）What does Curry's father think is cool about Curry's invention？
A．It used some of the most advanced technology．
B．It simply combined technologies that existed．
C．It could accelerate production of new technology．
D．It is the most advanced among similar products．
（4）Why did Curry's father start a campaign to raise money？
A．To conduct experiments to test the invention．
B．To get other children devoted to inventions．
C．To support a charity of medical aid for children．
