（1）语境衔接题。根据上文You don't have to completely avoid foods you enjoy. （你不必完全避免你喜欢的食物。）以及下文That usually only leads to cheating or giving up on your new eating plan.A better approach is to make a few small changes at a time.（这通常只会导致作弊或放弃你的新饮食计划。一个更好的方法是一次做一些小的更改。）可知，改变饮食习惯不必一次完成。没有必要一下子改变一切，否则就会导致你有可能会放弃你的新饮食计划。C项"And you don't have to change everything all at once你不需要一下子改变所有的东西。"符合语境。故选C。
（2）联系上文题。根据上文Prepare more of your own meals.（多准备一些你自己的饭菜。）可知，需要为自己多准备一些饭菜。空处进一步解释这样做的原因。G项中的"Cooking more meals"和上文"Prepare more of your own meals."相呼应。G项"Cooking more meals at home can help you take charge of what you're eating在家多做饭可以帮助你控制自己的饮食。"符合语境。故选G。
（3）联系下文题。根据下文When cutting back on unhealthy foods in your diet，it's important to replace them with healthy alternatives. （当你减少饮食中不健康的食物时，用健康的替代品代替它们是很重要的。）可知，本段所给建议为要用健康的食物替代饮食中不健康的食物。A项"Make the right changes做出正确的更改。"符合语境。故选A。
（4）语境衔接题。根据上文Focus on how you feel after eating.This will help develop healthy new habits and tastes. （关注你吃完饭后的感觉，这将有助于培养健康的新习惯和新口味。）可知，要关注吃东西后的感觉。空处和下文"The more junk food you eat，the more likely you are to feel uncomfortable，boring or tired out.（你吃的垃圾食品越多，你就越可能感到不舒服、无聊或疲惫。）可知，要关注吃东西后的感觉。并描述吃东西后的感觉。E项"The healthier the foods you eat，the better you'll feel after a meal你吃的食物越健康，饭后感觉就越好。"符合语境。故选E。
（5）联系上文题。根据上文Water helps flush our systems of waste products and poison，yet many of us go through life dehydrated （脱水的）—causing tiredness，low energy，and headaches.It's common to mistake thirst for hunger. （水有助于冲洗我们的废物和毒素系统，但我们中的许多人一生都处于脱水状态，导致疲劳、低能量和头痛。把口渴误认为饥饿是很常见的。）可知，多喝水有好处，如果喝水不足会导致脱水现象。F项中的Thus和前文构成因果关系，"drinking enough water"和本段的主旨句"Drink plenty of water. "相呼应，F项"So drinking enough water will also help you make healthier food choices所以喝足够的水也有助于你选择更健康的食物"。符合语境。故选F。

Do Weighted Blankets Work？ Sleep is supposed to be a natural thing，but if you wrestle with insomnia（失眠症），you may be tempted to try pieces of equipment that promise better sleep.（1）
    "They've become the sleep tool to have，" says Alanna McGinn，founder and lead sleep expert at Good Night Sleep Site. "I'm a huge supporter of them because they can work so well."
    About 32 percent of Americans don't get enough sleep，according to the Centers for Disease Control and Prevention.（2）        Insomnia impacts as many as 35 percent of adults from time to time，while 10 percent have chronic trouble falling and staying asleep.Choose one that's around 10 percent of your body weight.
    （3）        Inside is a layer of plastic，glass or metal balls surrounded by filling.McGinn says the blanket's heaviness acts as a touch therapy called deep pressure stimulation.Just as wrapping babies tightly can send them to sleep，these blankets help your heart and breathing rates slow and your body release feel-good hormones，including serotonin（血清素）.
    Are they effective？A 2020 review study in the U.S.looked at eight previous studies and concluded that weighted blankets helped reduce anxiety—but not necessarily insomnia.（4）        A randomized controlled study in Sweden looked at 120 people with insomnia and also depression or anxiety.（5）        People with conditions such as diabetes or breathing issues，however，should check with their doctor before using one. "And if you're someone who is a little afraid of an enclosed space，it's probably not the best thing for you，" adds McGinn.

A.It recommends at least seven hours a night for adults.
B.Those who used a weighted blanket slept better and were less tired or anxious.
C.The study found a significant rise in the related symptoms.
D.But other 2020 research tells a slightly different story.
E.One that might sound a little weird but that has been known to work is a weighted blanket.
F.Dealing with such problems can be more or less tricky.
G.Weighted blankets range between two and 14 kilograms

204441. （2023•临潼区•高一下期末）     Mounting evidence suggests that longtime sitting—a main part of modern-day life—is risky to your health，even if you exercise regularly.Based on these findings，doctors advise all adults to sit less and move more.But how often do we need to get up from our chairs？And for how long？
    Few studies have compared multiple options to come up with the answer most office workers want：What is the least amount of activity needed to counteract the health effects of a workday filled with sitting？
   Now a study by Columbia University exercise physiologists has an answer.Unlike other studies that test one or two activity options，the study tested five different exercise "snacks"，or short bursts of activity after a period of time's sitting：one minute of walking after every 30 minutes of sitting，one minute after 60 minutes，five minutes every 30，five minutes every 60 and no walking.
    The proper amount of movement，the researchers found，was five minutes of walking every 30 minutes.This was the only amount that greatly lowered both blood sugar and blood pressure.In addition，this walking routine had an impressive effect on how the participants responded to large meals，reducing blood sugar spikes（峰值） by 58% compared with sitting all day.Taking a walking break every 30 minutes for one minute also provided modest benefits for blood sugar levels throughout the day，while walking every 60 minutes，either for one minute or five minutes，provided no benefit.
    What we know now is that for best health，you need to move regularly at work，in addition to a daily exercise routine.While that may sound impractical，the findingow that even small amounts of walking sp read through the work day can greatly lower your risk of heart disease and other chronic （慢性的） illnesses.

（1）What does the study by Columbia University focus on？
A．What adultould do to keep exercising regularly.
B．When and where we need to sit less and move more.
C．Why longtime sitting every day is risky to our health.
D．How often and how long we need to walk from our chairs.
（2）What does the underlined word"counteract" in paragraph 2 mean？
A．Cancel out.
B．Give up.
C．Add to.
D．Benefit from.
（3）Which walking pattern is the most useful for health according to the text？
A．One minute of walking after every 30 minutes of sitting.
B．One minute of walking after every 60 minutes of sitting.
C．Five minutes of walking after every 30 minutes of sitting.
D．Five minutes of walking after every 60 minutes of sitting.
（4）What does the last paragraph show？
A．The risks of heart disease and other illnesses.
B．The suggestions on the health of the office staff.
C．The daily exercise routine sui table for everyone.
D．The ways of moving regularly at work every day.

    Wear protective equipment.
    The equipment you wear depends on the sport you play.Helmets are the most common protective equipment.They protect your head while you're playing football，baseball，softball，biking，skateboarding，and so on.
    Warm up.
    （2）       Doing some stretching can get you prepared to hit the field.By warming up，you get yourself ready to play.Warming up your muscles and practicing a sport help keep you safe，too.
    Know the rules of the games.
    Traffic lights help prevent crashes between the cars that drive on the roads together.This works because drivers know the rules and follow them.（3）        .When players know the rules of the game，fewer injuries happen.For example，you know that in soccer you can't come from behind，crash into a player's legs，and steal the ball.
    （4）
    Some rules don't have anything to do with scoring points.Some rules are just about protecting other people.For example，a diver would make sure that the pool was clear before diving in.Otherwise，he or she might land on someone else.
    Don't play when you're injured.
    This is a really important one.If you love sports，you may get right back in the game，even after an injury.（5）       it can lead to an even worse injury.

203995. （2023•师大附中•高一下期末）     Working out for 30 minutes every day "might not be enough" to counter the health issues created by long time sitting，according to a sweeping new study.
    The new study，unlike the past ones that examined sitting and formal exercise separately，ignoring light activities，involved 3702 people to find out how those all affected people's health indices（指数）.
    With the data collected，researchers characterized people by how they moved.The first group dutifully exercised for a half-hour and then sat，almost nonstop，for more than 10 hours a day.Another group similarly worked out for 30 minutes and sat for long hours.But，in between，they rose often and took walks around，spending time in light activities like fetching another cup of coffee.The third group sat，uninterrupted，for up to 10 hours，but also collected an hour of exercise most days.The final group，which the researchers named "the movers，" exercised about an hour most days，while also moving lightly for about two hours more.
    When the researchers cross-checked these groups against people's current health data，the first group had the worst indices.On the contrary，the other groups were all better off and to about the same extent，with relatively improved blood sugar control and cholesterol（胆固醇） levels and about 8 percent less body fat than the first group.
    "A single 30-minute，daily workout 'might not be enough' to reduce the downsides of long time sitting，" said Vahid Farrahi，the lead author of the new study."In addition to a brisk（轻快的） workout，we need to move lightly and often，cleaning，taking the stairs，taking a walk in the halls or just not remaining still."

（1）How is the new study different from the previous ones？
A．It examined sitting and exercise separately.
B．It proved that light activities were ignored.
C．It took light activities into consideration.
D．It suggested working out for a half-hour.
（2）What do we know from the data in the new study？
A．The first group spent a half-hour on light activities after long sitting.
B．The second group got similar improved health indices as the movers.
C．The third group collected an hour's exercise during 10 hours' sitting.
D．The movers got up every 30 minutes for formal exercise for an hour.
（3）What light activity is suggested to go with formal exercise？
A．Reading while sitting.
B．Swimming in the pool.
C．Working out in the gym.
D．Walking in the gym hall.
（4）What can we infer from Vahid's words？
A．It's better to exercise more often than half an hour every day.
B．Moving lightly and often is more useful than we have thought.
C．Working out harder and longer is better than just moving lightly.
D．A 30-minute workout has little help for long time sitting problems.

204079. （2023•西安中学•高一上期末） Your chair is your enemy.
It doesn't matter if you go running every morning，or you're a regular at the gym.If you spend most of the rest of the day sitting，you are putting yourself at increased chance of heart disease，cancers and an early death.In other words，even if you exercise energetically，sitting for long periods is bad for you.
So what's wrong with sitting？One is that sitting is one of the most passive things you can do.You burn more energy by chewing gum than you do sitting still in a chair.Compared to sitting，standing in one place is hard work.To stand，you have to tense your leg muscles，and the muscles of your back and shoulders.While standing，you often change from leg to leg.All of this burns energy.
For many people，weight gain is a matter of slow increase.Thus，a little more time on your feet today and tomorrow can easily make the difference between remaining thin and getting fat.So part of the problem with sitting a lot is that you don't use as much energy as those who spend more time on their feet. This makes it easier to gain weight，and makes you more likely to suffer from the health problems that fatness often brings.
Some people have advanced solutions：replace your sit-down desk with a stand-up desk.Make sure that your television can only operate if you are practising on an exercise bike.Replace your office chair with a therapy （治疗） ball：this too uses more muscles，and more energy，than a normal chair，because you have to support your back and work to keep balanced.But whatever you choose，know this.It is clear：be careful of your chair.

（1）The main purpose of writing this passage is to        .
A．suggest sitting less
B．advise exercising often
C．avoid gaining weight
D．escape standing more
（2）From this passage，we know that        .
A．standing burns nearly as much energy as sitting still does
B．taking exercise regularly but sitting more will do good
C．less exercise will reduce the chance of having disease
D．energy-burning activities will help you enjoy good health
（3）The underlined word "This" in paragraph 4 refers to "        ".
A．Gaining weight
B．Burning energy
C．Sitting too much
D．Standing more
（4）A therapy ball is mentioned in the last paragraph to        .
A．tell us to walk while working in the office
B．suggest a way to settle the sitting problem
C．support our back and keep us balanced
D．provide a better cure for our backache

203976. （2024•高新一中•高二下期末）     This week Surgeon General Vivek H.Murthy released a warning about the risks that social media presents to the mental health of children and teenagers.Adolescent mental health has been declining for years，and an increasing amount of research suggests that social media platforms could be partially to blame.But experts continue to debate just how much impact they have.
   Numerous studies demonstrate that adolescent rates of depression，anxiety and loneliness have skyrocketed in the U.S.and elsewhere since around the time that smartphones and social media became ever-present.
   Yet the role social media plays has been widely debated.Some researchers have sounded the alarm，arguing that social media provides the most credible explanation for problems such as enhanced teen loneliness.Other researchers have been sitting on the fence.In 2019 Jeff Hancock founding director of the Social Media Lab at Stanford University，and his colleagues completed an analysis of 226 scientific papers dating back to 2006.They concluded that social media us was associated with a slight increase in depression and anxiety but also improvements in feelings of belonging and connectedness.
   Some recent studies have attempted to clarify the link between social media and mental health，asking，for instance，whether social media use is causing depression or whether people are being more active on social media because they're depressed.In an attempt to present evidence，Massachusetts Institute of Technology economist Alexey Makarin and two of his colleagues conducted mental health surveys taken by college students across the country.Their study，published in 2022，found that swollen rates of depression and anxiety，as well as declined academic performance，followed Facebook's arrival.Makarin says much of the harm they documented came from social comparisons：students viewed the online profiles of their peers and believed them to "have nicer lives，party more often，have more friends and look better."
   "In total，there's an increasingly clear picture that，indeed，social media has a negative impact on mental health，" Makarin says. "We are not saying that social media can explain 100 percent of the rise of mental health issues...But it could potentially explain a sizeable portion."

（1）What do we know about social media？
A．It has negative influence on adolescent mental health.
B．It is the leading cause of adolescent depression.
C．It plays an important role in treating mental illness.
D．Its impact on mental health is still unknown.
（2）What is Jeff Hancock's attitude towards social media？
A．Critical.
B．Objective.
C．Favorable.
D．Indifferent.
（3）How does social media cause harm to teenagers according to Makarin？
A．By threatening their academic performance.
B．By presenting them with online profiles.
C．By encouraging them to party more often.
D．By making them feel worse-off than others.
（4）What is the main purpose of the text？
A．To advocate the harms of social media to teenagers' mental health.
B．To analyze the causes of worsening adolescent mental health.
C．To present findings on the link between social media and mental health.
D．To propose an effective approach to handling mental illness.

201988. （2023•新城区•二模） Childhood obesity（肥胖）isn't only caused by over eating.A lot of environmental and lifestyle variables—such as skipping breakfast，irregular sleeping patterns and less sleep time—also contribute towards this disturbing trend，says a new study.
   According to the study conducted by University College London's researchers，children who skip breakfast and sleep less are more likely to have bigger appetites and tend to consume more energy-rich foods throughout the day，leading to excessive weight gain.The team also found that smoking habit of mothers during pregnancy（怀孕）is also one of the contributory factors for a child being overweight.
   Interestingly，these results challenge the conventional belief that over-eating is main cause of increasing obesity rates among children.In addition，factors like watching too much television，consuming sugary drinks，eating fruits and introducing solid food sooner don't certainly lead to childhood obesity.
   The researchers used data from a multi-disciplinary research project that tracks the lives：of children from 19，244 families across the UK，born from September 2020 to January.2021.After analyzing the data，they found that in UK，83.3%of new babies had non-overweight and stable.BMI （身体质量指数）.Only 1% had a mildly increasing BMI，while another 2.5% tended to have a sharply increasing BMI.However，due to poor lifestyle choices and environmental factors，6% of the children were already overweight when they were three years old.
   The study authors concluded that modifying（更改） a child's environment early in life can go a long way in reducing their chances of gaining abnormal weight，which can also affect their health in later years.
   The researchers recommended that dealing with the childhood obesity calls for a mixture of preventive actions，for example，creating awareness among the families around the benefits of a healthy lifestyle and also instructing and supporting parents throughout the pregnancy，and even before and after it.

（1）What is paragraph 2 mainly about？
A．The effect of childhood obesity.
B．The irregular lifestyle of children.
C．The new trend of social development.
D．The causes of children being overweight.
（2）What do people usually think leads to childhood obesity？
A．Sleeping less and skipping breakfast.
B．Watching too much TV and playing games.
C．Smoking and introducing solid food sooner.
D．Consuming too much food and sugary drinks.
（3）What can we know from the data of the research in UK？
A．The obesity rates among children were not high.
B．Most of the children didn't get energy-rich foods.
C．The irregular lifestyle had little effect on children.
D．The study result was beyond researchers' expectation.
（4）What suggestion do the researchers offer parents？
A．Improving the living environment.
B．Protecting children from any harm.
C．Increasing their physical activity.
D．Raising awareness of healthy lifestyle.

212638. （2025•铁一中学•高二下期中）     People vary in how well they discriminate and identify foods.The variation is explained by a general ability to recognize objects.We researchers originally theorized the variability might also be associated with people's attitude toward new foods.Those who endorse statements like"I am particular about what I eat"have food neophobia—refusal of food novelty.Sure enough，our study did find picky eaters scored worst on our tests of food recognition：Food neophobia is negatively correlated with food recognition ability.
    While we were publishing our finding，scientists were debating new findings about how the brain reacts to food and color.Different research groups had identified brain areas in the visual system that responded preferentially to images of food.For instance，looking at a bowl of noodles would activate these brain areas，but not looking at a pile of string.The scientific disagreement was about what it meant to identify a selectivity for food in brain areas already known for their responsiveness to color.
    We repeated our initial study with gray-scale images of food.The result showed without color，people unsurprisingly made more errors，mistaking different dishes as the same，but the pattern of variation across people was otherwise unchanged.Those with a higher general visual ability did better with food.We also found one effect of removing color：Food neophobia was no longer correlated with food recognition ability.It was as if whatever advantage the adventurous eaters had gained over picky ones was all dependent on color.
    We then made an entirely new prediction：Would people with color blindness be less food neophobic than those with normal color perception？Because the colorblind experience food in a restricted range of color，certain signals that raise flags about freshness，safety，or otherwise drive anxiety about novel food could be limited.
    We invited participants online，based on how they answered one question about color blindness buried in a long screening questionnaire.The survey suggested colorblind people were indeed less food neophobic than the non-colorblind.Seeing the world with a narrow color range seems to ease an emotion-based resistance to novel foods.
    Our findings pave the way for addressing extreme cases of food neophobia.As researchers learn more about the complicated relevance between color perception and food，we might develop targeted interventions to improve dietary habits.

（1）What does the underlined word"endorse"mean in paragraph 1？
A.Comment on.
B.Approve of.
C.Worry about.
D.Argue against.
（2）What's the purpose of writing paragraph 2？
A.To illustrate an argument.
B.To emphasize the value of science.
C.To explain the background of later tests.
D.To indicate a positive academic atmosphere.
（3）Why are colorblind people less food neophobic according to the study？
A.They're born with a bigger appetite.
B.They're more expert at recognizing food.
C.They prefer to take risks and try fresh things.
D.They fail to perceive some food signs causing tension.
（4）How did the author uncover the effect of color on emotional responses to food？
A.By experiencing food diversity firsthand.
B.By analyzing feedback from respondents.
C.By testing brains' reaction to colorful foods.
D.By monitoring picky eaters' dietary variations.

203748. （2024•西工大附中•高二上期末）     A key part of starting to exercise is choosing when to work out.Morning，afternoon，or evening：Which time is best？Scientists have studied this dilemma extensively.
    For beginners，morning workouts are often the most frightening.Trading a cozy，nurturing bed for an unpleasant，unforgiving fitness center can be a rude awakening to say the least.But morning workouts have their advantages.Challenging the body triggers the release of endorphins（内啡肽），which can make you more productive and attentive at work.Moreover，for those who struggle to fall asleep at night，habitual morning exercise may help to reset their circadian rhythms，the internal，biological processes that regulate the24-hour sleep-wake cycle.
    But early exercisers may not be able to achieve peak performance.Stiffer muscles，fewer stored energy reserves from overnight fasting，and a.slightly cooler body temperature in the morning add up to disturb exercise output.Therefore，more enthusiastic exercisers might prefer working out in the afternoon.A small，12-week study focusing on pre-diabetic and diabetic men found that afternoon training produced slightly more beneficial metabolic（新陈代谢的）effects and resulted in a little more fat loss compared to morning training.
    Finally，some folks may decide to work out later in the evening.Studies centered around this time of day tend to focus on whether or not nightly exercise negatively impacts sleep quality.Gathered research suggests it does not and，instead，actually improves sleep.However，intense exercise performed within an hour of one's bedtime absolutely will make it more difficult to fall asleep.For this reason，most exercise experts recommend at least 90 minutes of downtime between the conclusion of an exercise session and attempting to fall asleep.
    Whether morning，afternoon，or evening，it is optimal（最佳的）if exercise timing remains somewhat consistent，research has found.For example，a competitive marathon runner will exhibit the best performance when his/her exercise training sessions occur at the same time-of-day as the marathon.Still，it is perfectly fine to mix up your workout times to fit with your schedule.The average person need not worry over when to work out just because of some slight bodily differences based on time-of-day.Regular exercises，after all，perhaps the single best thing that humans can do for their health，and ideally，it should serve as stress relief rather than something to stress over.

（1）Which of the following can benefit a man with sleeping disorder？
A.Sleeping immediately after workouts.
B.Regular workouts between 7 a.m.and 10 a.m..
C.Reducing the exercise time by at least 90 minutes.
D.Exercise between 2 p.m.and 5 p.m..
（2）Which of the following is right for diabetic men？
A.It is hard to lose weight in the morning.
B.Morning exercise produces harmful metabolic effects.
C.Diabetic men are easy to lose more fat.
D.Exercise may be more efficient in the afternoon.
（3）What can be inferred from the last paragraph？
A.The average person varies slightly in body.
B.A marathon runner will perform best in the training.
C.It's good to exercise at the same time every day.
D.It is fine to exercise ahead of schedule.
（4）Which one is the most suitable title？
A.Exercise：A dilemma
B.AM or PM：When is the best time to exercise？

204242. （2023•长安区一中•高二上期末）     All it takes is three continuous nights of sleep loss to cause your mental and physical well-being to greatly worsen.
    A new study looked at the consequences of sleeping fewer than six hours for eight nights on end — the minimum duration of sleep that is necessary to support best health in average adults.
    Lead author Soomi Lee，assistant professor at the University of South Florida，found the biggest jump in symptoms appeared after just one night of sleep loss.The number of mental and physical problems steadily got worse，peaking on day three.At that point，research shows the human body got relatively used to repeated sleep loss.But that all changed on day six，when participants reported that the severity of physical symptoms was at its worst.
    "Many of us think that we can pay our sleep debt on weekends and be more productive on weekdays." Lee said. "However，results from this study show that having just one night of sleep loss can significantly weaken your daily functioning."
    Data provided by the Midlife in the United Study included nearly 2000 middle-aged adults who were relatively healthy and well-educated.Among them 42% had at least one night of sleep loss，sleeping 1.5 fewer hours than their typical routines.
    They recorded their mental and physical behaviors in a diary for eight days in a row，allowing researchers to review how sleep loss causes wear and tear on the body.Participants reported a pile-up of angry，nervous，lonely，bad-tempered and frustrated feelings as a result of sleep loss.They also experienced more physical symptoms，such as upper respiratory issues，aches，gastrointestinal （肠胃的） problems and other health concerns.

212982. （2023•长安区一中•高一上期中）     Even small amounts of physical activity，like quick walking，may greatly lower the risk of depression（抑郁），according to a new data analysis （分析）.
    Recommended levels of exercise in the United States，according to the US Centers for Disease Control and Prevention （CDC），include aerobic （有氧的） activity at proper levels for 2.5 hours a week，along with a workout of all major muscle groups twice a week.Or，a person can choose a high-level aerobic exercise，such as running，for 1.25 hours each week，along with the same amount of strength training.
    Middle-to-high-level exercise is good for us，according to the CDC.It improves sleep，lowers blood pressure，protects against heart disease and diabetes，reduces stress，improves mood，and fights anxiety and depression.But in today's busy world，many people find it difficult to fit in a jog or a visit to the gym. Add depression to the mix，and the motivation for exercise drops even further，experts say.
    The analysis，published Wednesday in the journal JAMA Psychiatry，looked at 15 studies involving over 190，000 people to determine how much exercise was needed to reduce depression.
   Adults who did activities equal to 1.25 hours of quick walking per week had an 18% lower risk of depression compared with those who did not exercise，the study said.Moving up to an "activity amount equal to 2.5 hours of quick walking per week was associated with 25% lower risk of depression，" the study authors said.
    The benefits were strongest when a person changed from being a couch potato to adding movement to the day，the study said.However，exercising over the recommended levels did not provide any additional benefits.
    "Our findings therefore have an important new influence on health doctors making lifestyle recommendations，especially to inactive individuals who may regard the current recommended target of exercise as unrealistic，" the authors wrote.
    A study in 2018 found similar results：People who exercised had about 43% fewer days of poor mental health. "Even just walking three times a week seems to give people better mental health than not exercising at all，" said study author Adam Chekroud，an assistant professor of psychiatry at Yale University.

（1）Why does the writer use the figures in Paragraph 2？
A.To make out which exercise is better for health.
B.To recommend the proper levels of exercise.
C.To show the benefits of doing exercise.
D.To provide different ways of exercise.
（2）How do you understand the underlined sentence in Paragraph 3？
A.Running may possibly add to depression.
B.People tend to exercise more when depressed.
C.Depressed people are less willing to exercise.
D.Working out regularly helps increase motivation.
（3）What does the analysis published in JAMA Psychiatry suggest？
A.Over 190，000 people suffer from poor mental health.
B.2.5 hours of quick walking per week is a must for adults.
C.The recommended levels by CDC go for people of all ages.
D.A couch potato benefits much when taking proper exercise.
（4）Which of the following agrees with Adam Chekroud's idea about exercise？
A.Where there is a will，there is a way.
B.Half a loaf is better than no bread.
C.Rome wasn't built in a day.
D.Practice makes perfect.

212780. （2025•西安一中•高二下期中）     When I was a child I was often told what not to eat. "You don't want to get fat" was on constant repeat throughout my childhood.It really messed up my relationship with food —something that took me years to overcome.Because of this，I'm careful not to connect what my kids weigh with their worth as people.I encourage my daughter to make healthy snack choices and often dissuade （劝阻） her from a second dessert.But one day when I heard her saying "I think I'm too fat，" my heart sank.It made me wonder if giving her advice on snacks was having an unintentionally negative impact.
    According to Charlotte Markey，a professor of psychology，food is one of the rare subjects where，as parents，saying less is more. "There are so many things in parenting that are good to talk through，but I'm not convinced that food is one of them，" she says. "It just creates some worries and insecurities in kids that aren't necessarily healthy."
    Instead，she recommends applying a well-known concept among nutrition experts called the "Division of Responsibility，" where parents provide a variety of mostly healthy foods to their kids at fixed times，and the kids themselves decide what and how much they want to consume —even if that means occasionally eating more cookies than carrots.
    Allowing kids to eat what they want also exposes them to the natural consequences of their decisions. "When your child says， 'My stomach hurts，' you can say， 'Well you had a lot of sugary foods and you might feel better if you made some other choices，'" says Markey. "Let them feel like they have some control over it."
    I've been trying out these strategies and I've found that when I'm less restrictive，they do make better decisions. "Feeding is a long game，" says Markey. "The food you have available makes a huge difference.Even if they don't eat it，they' re seeing it.And then all of a sudden it clicks."

（1）What can be inferred about the author from the first paragraph？
A.She is upset by her kids' weight.
B.She is critical of the way she was fed.
C.She is interested in making food.
D.She is particular about what she eats.
（2）Which of the following would Markey disapprove of？
A.Allowing kids to eat cookies occasionally.
B.Offering various foods to kids at fixed times.
C.Explaining to kids the risks of taking snacks.
D.Talking with kids about school at mealtimes.
（3）What should kids do according to the "Division of Responsibility"？
A.Make diet decisions on their own.
B.Share their food with other kids.
C.Eat up what is provided for them.
D.Help their parents do the dishes.
（4）What does the author think of the strategiee has been following？
A.Costly.
B.Complex.
C.Workable.
D.Contradictory.

201617. （2025•临潼区•二模）     Americans' waistlines have grown relentlessly for decades：a costly，debilitating and deadly trend that prompted observers to wonder if and when they would finally stop expanding.Well，the federal government released data Sept.24 showing that the obesity epidemic，one of the most terrible public health crises，might have stopped worsening.And there is the reason to imagine the numbers will get better from here.
    Obesity has been linked to asthma，heart disease，stroke，Type 2 diabetes，some cancers and severe outcomes from respiratory（呼吸的） illnesses.The latest National Health and Nutrition Examination Survey，which interviewed nearly 6，000 individuals between August 2021 and August 2023，showed that the epidemic of obesity among adults was 40.3 percent -down from 41.9 percent in the previous survey，conducted between 2017 and 2020.It is the first such decline in more that a decade，and it could mean that，at long last，"obesity epidemic is potentially balancing in the United States，"as a Centers for Disease Control and Prevention official told us.
    Multiple caveats（警告） apply.Even if it has plateaued，the obesity rate is still far too high，having more than tripled since the early 1960s，when it stood at 13 percent；a decade ago，in 2013-2014，it was 37.7 percent.The CDC report indicates that the"severe"obesity rate is up from 7.7 percent a decade ago to 9.7 percent in the latest survey.The statistical tool CDC uses to define obesity，body mass index（BMI），which measures neither body fat nor its distribution within a given individual.And as of yet，there is no precise explanation for the encouraging new data.Factors such as genes，certain medications，sleep quality，gut fauna，stress，nutrition and access to health care all affect obesity.
    In a 2023 study，scientists at the National Kapodistrian University in Athens hypothesized（假设）that obesity might be peaking worldwide because it has reached"a biological limit".That is，nearly all the people genetically susceptible（易受影响的） to obesity are obese already.Another possibility：production of highly processed foods has maxed out relative to the world's ability to consume it.Also，public health campaigns might have had their intended effects：increased awareness，promoting healthier food choices and more opportunities for physical activity.
    The decline in the obesity rate was not quite as dramatic as the one in teen vaping（电子烟）；the data might not even suggest a permanent plateau in obesity rates.Still，the numbers give reason for hope-and more hard work.

（1）What's the main idea of the first paragraph？
A.There are less fat people than ever before.
B.There are more fat people than ever before.
C.Americans are worried about their waistlines.
D.Americans don't know when they will be thin.
（2）What can be known from the passage？
A.The obesity rate is not so high any more according to the recent survey.
B.Obesity will not exist in the United States according to the recent survey.
C.Obesity epidemic decreases a little within twenty years for the first time.
D.BMI measures both body fat and its distribution within a given individual.
（3）What does the underlined word"plateaued"in the third paragraph mean？
A.Reached the peak.
B.Reached the balance.
C.Reached the bottom.
D.Reached the standard.
（4）In which column of the newspaper can we read the passage？
A.Culture.
B.Biography.
C.Literature.
D.Health.

205489. （2020•莲湖区•高一下期末） Churchill，Manitoba is a small town．The northern winds roll through it from Canada's Hudson Bay．It might be just another point on the map if not for its seasonal settlers．
   It happens like clockwork every fall that hundreds of polar bears make their way through the town to the freezing bay where they hunt for seals after the ice packs enough to support their weight．The animals have been connected with Churchill since at least 1619．That's when Norwegian explorer Jens Munk and his sailors recorded making a meal of one bear while they wintered in the area． "It was of good taste and did not disagree with us．" That's what Munk wrote in his journal．
   Over the years，the animals' coming has earned the town the name of "Polar Bear Capital of the World．" Today，Churchill's bear population goes beyond its human population．There used to be about 7，000 residents but now only 813 living there．There was no such thing as an organized tour group to see the bears until 1980．The town might have been in terrible financial hardships．But the growing bear tourism industry helped．
   Today，some 10，000 tourists come to the town to see polar bears for six weeks in autumn every year．But the reasons why they come are different from before．Everyone was happier and they had such a good time seeing polar bears．Now things have changed because the word is out that this Western Hudson Bay population of bears，Churchill Bears，are going to be the first population of polar bears to die out．So when the tourists come up，they all have a little bit of a lump in their throats（如鲠在喉）because they're looking at a beautiful bear，but they're also looking at a dying-out bear，which makes the whole attitude toward the bears different．Unfortunately，that's becoming the major part of the whole attraction of the tours as well．Come and see the bears before it's too late．

（1）What can we learn about Churchill polar bears from the text？
A．They have eaten up the seals in the Hudson Bay．
B．They come to Churchill at the same time every year．

B．They attract many hunters to come here．
C．They bring much tourist income．
D．They supply food to locals．
（4）What is the main reason why tourists go to Churchill now？

202673. （2020•西安中学•三模） Even though vaccination（接种疫苗） is a powerful defense against disease，some voices are against it．In a recent letter，the American Medical Association（AMA） urged big social media including Amazon，Facebook and Google to take action to defend medical science on their platforms．
   It said that vaccine-preventable diseases that do harm to the public health like measles（麻疹） are on the rise．Measles cases worldwide jumped more than 30% in 2017 compared to 2016，with the largest increases seen among nations in the Americas，Europe and the Eastern Mediterranean．Vaccine-preventable diseases are increasing largely because many people are unwilling to get vaccinated．And some of these people even encourage others to refuse vaccination．So this year，the World Health Organization （WHO） declared the anti-vaccination movement a top-10 health threat．
   "Vaccination is one of the most cost-effective ways of avoiding disease - it currently prevents 2-3 million deaths a year，and a further 15 million could be avoided if global coverage of vaccinations improved，" WHO said．
   A research article published in 1998 in a medical journal suggested a link between a vaccine and the development of autism（自闭症） in young children．Although the research has been suspected and many other studies have proved that vaccinations do not cause autism，the article is still impressing people strongly today．Another reason for the growth in the anti-vaccination movement is widespread misinformation on social media，which can turn people against vaccination．If a concerned parent consistently sees information in their Newsfeed that casts doubt on the safety of vaccines，it could cause them to disregard the advice of their children's physicians and public health experts and refuse to follow the recommended vaccination schedule．So access to true information about vaccine safety is badly needed．

（1）What does the AMA require social media to do on their platforms？
A．Unite to develop new vaccines．
B．Stop vaccine misinformation．
C．Give up the anti-vaccination movement．
D．Introduce vaccine-preventable diseases．
（2）Why does the author mention the measles cases？
A．To declare measles can be prevented．
B．To prove vaccination doesn't work well．
C．To show the result of anti-vaccination．
D．To explain the reason for avoiding vaccination．
（3）Which of the following DOESN'T play a role in the anti-vaccination movement？
A．The costs of vaccination．
B．People's concerns over vaccine safety．
C．A research relating vaccination to autism．
D．Misinformation spread on social media platforms．
（4）What is the author's attitude towards vaccination？
A．Doubtful
B．Ambiguous
C．Positive
D．Negative
