281080. （2025•铁一中学•高二上一月）     We watch our salt and fat intake to protect our hearts.We exercise and take calcium to protect our bones.We use sunscreen to protect our skin.But what can we do to protect our eyes，all year round？A lot. （36）       .
    Invest in quality sunglasses
    To shield your eyes，wear sunglasses certified to block out 99 to 100 per cent of UVA and UVB light. （37）       . "In fact，if the lenses are dark but not UV-protected，that's worse for your eyes，because when you're looking through dark lenses your pupils dilate，which lets more UV light inside to do damage，" says Dr Esen Akpek，a professor at Johns Hopkins University.
    Wear safety glasses when needed
    You don't have to be doing construction work or factory work to need protective eyewear. （38）       .It's estimated that up to 90 per cent of sports-related eye injuries are actually preventable with proper eye protection. "I see people who've been gardening，leaned forward and got poked in the eye by a branch，" says Dr Davinder Grover，an ophthalmologist at Glaucoma Associates of Texas.
    Invest in an air purifier
    （39）       .Outdoor cold and wind can be drying，too，while pollution and allergens can cause irritation.In addition to lubricating eye drops， "air purifiers and humidifiers are our friends，" says Akpek.
    See an eye specialist regularly
    Routine checkup helps maintain good eye health，so please don't forget to see an eye specialist for a checkup regularly，if possible. （40）       .

A．Safety comes first for various outdoor activities
B．Surprisingly，dark lenses aren't necessarily the most protective
C．Indoor heating and air conditioning can dry out the air —and the eyes
D．Gardening，home repairs and sports all pose the risk of trauma to the eye
E．Not all eye problems are noticeable，and all are best treated when found early
F．By incorporating these lifestyle steps，your eyes will stay healthy throughout the year
G．We have asked experts what lifestyle steps people should take to protect their vision and eye health

213850. （2022•师大附中•高二下期中） A strong coffee after a poor night's sleep is the kick-start many people need in the morning but new research suggests that it might be best to have a bite to eat first.
   A study has found that drinking coffee first can have a negative effect on blood sugar control — a risk factor for diabetes （糖尿病） and heart disease.
   "We know that nearly half of us will wake in the morning and，before doing anything else，drink coffee — subjectively the more tired we feel，the stronger the coffee，" said Professor James Betts，at the University of Bath in the UK.
   For their study，researchers at the University of Bath got 29 healthy men and women to take part in three different overnight experiments，with at least a week between them.
   In one，the participants had a normal night's sleep，roughly from 11 p.m.to 7 a.m.，and were asked to consume a sugary drink on waking in the morning.Then they experienced an interrupted night's sleep，where the researchers woke them every hour for five minutes by sending them text messages to which they had to respond — and upon waking were given the same sugary drink.
   On another night，participants experienced the same sleep interruption，but this time were first given a strong black coffee 30 minutes before consuming the sugary drink.
   They found that one night of interrupted sleep did not worsen the participants' blood sugar and insulin （胰岛素） responses when compared to the normal night's sleep — although previous research suggested that losing many hours of sleep or many nights of poor sleep could have a negative effect.However，strong black coffee consumed before breakfast actually increased the blood sugar response by around 50% — suggesting that relying on coffee after a bad night to stop feeling sleepy could limit your body's ability to tolerate the sugar in your breakfast.

（1）What does the underlined word "kick-start" in paragraph 1 refer to？
A．A kind of sport.
B．A kind of belief.
C．A kind of medicine.
D．A kind of power.
（2）What was unchanged in the three experiments？
A．The duration of sleep.
B．The sugary drink.
C．The blood sugar response.
D．The intake of coffee.
（3）What increased the participants' blood sugar response most before breakfast？
A．A normal sugary drink.
B．A normal night's sleep.
C．A cup of strong black coffee.
D．An interrupted night's sleep.
（4）How did researchers draw the conclusion？
A．By comparing the results.
B．By listing some examples.
C．By surveying the participants.
D．By referring to some documents.

213192. （2024•沣东中学•高二下期中）     It's no secret that sleep is important to your overall health，but a lack of sleep could have great effects on your heart，a new study shows.The researchers said people with insomnia（失眠症）are more likely to have a heart attack.
    Insomnia is the most common sleep disorder in the US，the researchers wrote in their report，noting that 10% to 15% of people in the US struggle with it.The meta–analysis of previously published research suggests that the potential association between insomnia and heart attack risk is strongest in women.
    Dr.Martha Gulati，director of prevention at the Cedars-Sinai Smidt Heart Institute，said that most of her patients are women and that insomnia is a noted risk factor for women who have had any form of ischemic heart disease."We see it probably in 1 in 10 patients in the United States，"said Gulati，who was not involved in the new research."It is my impression that almost everyone experiences insomnia at some point in their life.The estimate is that 1 in 2 adults experience it at some point in their life，maybe in the short term because of stressful moments."
    For their analysis，the researchers defined insomnia as a sleep disorder with three main symptoms（症状）：Difficulty falling asleep，difficulty staying asleep and waking early and being unable to fall back asleep.
    The study also found an association between increased heart attack risk and how long a participant slept each night.Those who slept five hours or less had the highest association with heart attack risk and were 1.56 times more likely to have a heart attack than people who slept seven or eight hours.Longer sleep duration wasn't always more protective.The study found that people who slept six hours a night had a lower risk of a heart attack than those who slept nine hours or more."A lot of studies have pointed somewhere between seven and eight hours of sleep being the magic number for us，"another researcher said."There is obviously variability for everyone，but too much sleep is rarely the issue."

（1）What's the function of the first paragraph？
A.To list a fact.
B.To warn the readers.
C.To introduce the topic.
D.To draw the readers' interest.
（2）What can we infer from Gulati words？
A.Insomnia is unavoidable in the short term.
B.Insomnia is a common phenomenon in life.
C.Heart attack often happens during insomnia.
D.Women are less experienced in dealing with insomnia.
（3）What inspiration can we get according to the sleeping time？
A.Put quality before quantity.
B.Too much is as bad as too little.
C.Bite off more than one can chew.
D.Hope for the best，but prepare for the worst.
（4）What's the author's attitude to the relationship between insomnia and heart attack？
A.Pessimistic.
B.Indifferent.
C.Objective.
D.Positive.

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.

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

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.

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.

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.

213250. （2023•交大附中•高二上期中） Some women say the voice in their head gets kinder as they enter midlife，while other women become more critical of themselves.The difference in views appears to be related to the ability to accept age-related changes to their body，researchers have found.
   In 2013，Professor Paxton，of the Universityof La Trobe's Department of Psychology，was interviewed on ABC Melbourne about body image and well-being in women entering midlife.The ABC posted on their Facebook page the topic of the program and the question：Does the voice in your head get kinder as you get older？
   The study found 56 percent of comments suggested the voice in women's heads did get somewhat kinder with age.This view was associated with women accepting the age-related changes in their body as normal. "If they gained weight or they got wrinkles，it was a normal part of aging and they felt fine about it and it didn't disturb their sense of self，" Professor Paxton said， "They were more likely to value health and well-being as opposed to appearance."
   On the other hand，40 percent of comments suggested the voice did not get any kinder with age.This view was associated with women finding it difficult to accept being so different from the youthful ideal of women that is upheld in advertising and in the media.Women who expressed this view were concerned about how "invisible" they had become as a consequence. "They reacted negatively to the changes in their bodies as they aged and were very much aware that in our culture，youthful bodies are idealized，" Professor Paxton said.
   Understanding why some women are preoccupied with body image in midlife more than others is important given that having a bad body image can lead to physical and mental health problems，Professor Paxton said.This can include self-consciousness and anxiety，eating disorders，and an unwillingness to show oneself in public，which can reduce the amount women exercise or socialize. "They become unsociable and don't fulfill their full potential.Those sorts of things can make a person very unhappy."
   She said the insights from studies like this support the use of cognitive（认知的）behavioral therapy （治疗） designed to help women in midlife who have a preoccupation with body image to change negative thought patterns.This would involve discouraging them from comparing themselves to younger women，and encouraging acceptance of bodily changes related to age，and "self care" behaviors that improve health and well-being.

（1）What causes the difference in women's opinions on body image？
A．Women's self-acceptance.
B．Professors' advice.
C．The impact of Facebook.
D．Personal health.
（2）What does the underlined word "upheld" in paragraph 4 probably mean？
A．Introduced.
B．Tested.
C．Advocated.
D．Praised.
（3）How can women change negative thoughts about a bad body image？
A．By trying to show themselves in public.
B．By adopting a new thinking model.
C．By doing as much exercise as possible.
D．By comparing themselves to younger women.
（4）What is the purpose of the text？
A．To show public responses to the changes in their bodies.
B．To explain that health is more important than appearance.
C．To criticize views on body image expressed in the media.
D．To give advice to middle-aged women on bodily changes.

218074. （2023•田家炳中学•高二上二月） There are hundreds of bacterial（细菌的） species in our stomach.Bacterial diversity is a good thing，a general contributor to and marker of good health.But what does a healthy stomach look like？Studies indicate that the composition varies by many factors.
   One of the most important，it turns out，is who you currently live with.Researchers have come to the conclusion：Diet and heritability（遗传力） are known to affect the microbiome（微生物组），but social relationshipape it most—especially when it comes to marriage.The Dutch Project，which studied microbes in 8，208 individuals belonging to three generations，finds that the heritability of microbes is only 1.9 percent.They noticed much greater similarity among the unrelated individualaring a household than among relatives who do not share households，including twins whose living situations differ in adulthood.
   The researchers found that nearly 50 percent of microbial types were significantly affected by cohabitation.In general，the microbiomes of all types of cohabitors （including parents and children） were more similar than those of participants living separately no matter their relatedness.Married couples who report having a close，loving relationship have the most similarity.Evidence of microbial sharing，especially of rare species，shows exchanges through interactions.And that puts highlight on acts of close relationship—including kissing.Scientists have known for decades that social relationships，especially marriage，powerfully affect health.Not only are the microbiomes of cohabiting couples more similar to each other；they also are more similarly diverse.There is a greater richness of species than in unmarried，noncohabiting individuals.
   Despite the dominating influence of a close，cohabiting relationship，the microbiome can be different in diet，especially one rich in plant fiber.It can also be influenced by behavior，such as farming and gardening and exercise.Moreover，it's adaptable to environment—green space and pollutants around you.Living in a rural environment brings increases in bacteria linked to health，and decreases in bacteria that are harmful.Living with pets also has a positive effect on the microbiome，while exposure to air pollution，especially car exhaust，and passive exposure to cigarette smoke have negative effects.
   It can also be affected by direct addition of specific species of bacteria，delivered in consumable probiotics（口服益生菌）.There are probiotics now marketed for digestive health，others aimed at immune health，and still others for boosting mood.Now that it's clear that social relations play the largest role in the makeup of the microbiome，can probiotics for singles be far behind？

（1）Which group has the most similar microbiomes？
A．Husband and wife.
B．Adult twins.
B．Grandfather and grandson.
D．Colleagues.
（2）What can we learn from this passage？
A．Diet has a dominating influence on microbiomes.
B．Cohabitation is helpful for us to have a balanced diet.
C．Social relations play a similar role as some probiotics.
D．The microbiomes in couples are less diverse than singles.
（3）Which would be the best title for the passage？
A．Who Are the Healthiest People？

213269. （2024•西安八十五中•高一下期中）     How many times have you heard that reducing stress is important for good health？But stress isn't always the enemy.In fact，research suggests some is actually good for you，with possible benefits ranging from better brain function to healthier aging.
    Firstly，it's ubiquitous：Research suggests people feel at least some stress on 90% of their days.When stress worsens for a long time and can't be solved，it can cause mental and physical health problems，even raising your risk for conditions like heart disease.But in most cases，a stress response （反应） is important.It can help you get through a hard time or even escape physical danger.And，when stress is managed well，it can lead to better health and happiness in the future.
    Stress can be damaging—but proper amount of stress can be helpful，according to Assaf Oshri，a professor at the University of Georgia.Oshri says，"Resilience （适应力） comes from your interactions （相互作用） with the environment.If people don't experience any stress，they may not build up resilience.If they experience too much，their happiness may suffer.But there seems to be a balance between the two，where stress improves mental health and helps people recover from difficult situations."
    When people face pressure，some approaches can also be taken to deal with it.Playing sports can help to find a balance in the face of stress，according to some experts.Turning to loved ones during tough times is important too.And if you can，remind yourself that stress is a difficult but necessary part of life.
    "You can't choose exactly what happens to you，but you can choose your response in the moment，" Jonathan Rush，a professor at the University of Victoria in Canada，says. "Having the idea that you can overcome things，you can grow from things；whatever happens，you will have a path forward—that's what matters most."

（1）What does the underlined word "ubiquitous" mean in paragraph 2？
A.Special.
B.Common.
C.Popular.
D.Interesting.
（2）What benefit does proper pressure bring to people according to Oshri？
A.It can help people keep a balance between life and work.
B.It can increase people's interactions with each other.
C.It can help people know their physical danger.
D.It can promote people's mental health.
（3）What is paragraph 4 mainly about？
A.The influence of sports on stress.
B.The ways to deal with stress.
C.The approaches to having a happy life.
D.The key to avoiding challenging times.
（4）According to Rush，what is most important when facing stress？
A.Having a positive response.
B.Explaining what happened.
C.Relying on your loved ones.
D.Learning from others' experiences.

213611. （2023•莲湖区•高一下期中） A healthy diet may not offset（抵消） the effects of a high salt intake on blood pressure，suggests a new study.The research，from scientists at a number of institutions，studied the diets of over 4，000 people.The resultowed that people eating higher amounts of salt had higher blood pressure—no matter how healthy a person's overall diet.
   The scientists behind the research are now advising people to monitor their salt intake—and food companies to lower the salt content in their products.
   High blood pressure affects more than one in four adults in the UK，and increases the risk of a number of conditions including heart attacks and stroke.It's thought that vitamins and minerals in fruit and vegetables might in some way affect blood vessels（血管），enabling them to lower blood pressure.Previously，experts believed that eating high amounts of fruit and vegetables might help offset the effects of high salt on blood pressure.However，while these foods do tend to lower blood pressure，the new research suggests they do not offset the adverse influence of high salt intake.
   In the paper，the team studied data from the so-called INTERMAP study.In this study published in 2018，scientists tracked the diets of 4，680 people，aged 40-59，from the USA，the UK，Japan and China.The researchers found a link between high blood pressure and high salt intake，even in people who were on a healthy diet.
   The recommended upper limit of adult salt intake in the UK is 6 g a day.The study found that the average salt intake across the study was 10.7 g a day.The average intake for the UK was 8.5 g，while the intake for the USA，China and Japan were 9.6 g ，13.4 g and 11.7 g respectively.
   Increasing salt intake above this average amount was linked to an increase in blood pressure.Dr Queenie Chan，joint lead author of the research，said the research shows the importance of cutting salt intake.

（1）What can food industry do to help lower people's high blood pressure？
A．Make salt-free food only.
B．Monitor the quality of their products.
C．Take control of their salt production.
D．Cut down salt content in their products.
（2）What does the underlined word"adverse"in paragraph 3 mean？
A．Adventurous.
B．Harmful.
C．Brief.
D．Average.
（3）Which of the following nations has the highest average salt intake？
A．The USA.
B．China.
C．Japan.
D．The UK.
（4）What can be the best title for the text？
A．A healthy diet may not offset the effects of high salt intake
B．High blood pressure is related to high salt intake
C．Research shows the importance of cutting salt intake
D．People eating higher amounts of salt have higher blood pressure

213688. （2023•高新一中•高二下期中） Green exercise is a term used to describe any type of physical exercise that takes place in a natural environment rather than in a health club or gym. （1）       .Instead，it relies on the use of natural means of taking part in activities that improve strength and endurance with as little reliance on equipment as possible.
（2）       .For example，some consider a truly natural exercise experience requires that the individual wear clothing only made from natural fibers.Others consider barefoot running or walking with a big arena to be more desirable than running or walking with shoes.
   A slightly different approach to green exercise puts more stress on the fresh air，sunshine and involvement with the natural world，rather than the equipment or clothing used during the exercise. （3）       .Similarly，climbing a mountain using standard equipment and protective clothing would also be considered a green exercise.
   Many consider green exercise helps to reconnect human beings with the natural world.The interaction with nature helps to lower people's blood pressure，refresh their mind，and actually improve their self-esteem. （4）       .
   Not everyone believes that the green exercise is more beneficial than working out in a health club or gym. （5）       .Meanwhile，the use of fitness devices may result in more challenging workouts which help strengthen the heart and lungs in ways that more simplistic exercise in a natural setting would be difficult to manage.

A．A green gym uses as little equipment as possible
B．Spirits are also believed to be positively affected
C．Opinions on what truly green exercise means differ
D．Green exercise includes a range of activities exposed to nature
E．So riding a bicycle in the forest can be called a type of green exercise
F．It usually doesn't use fitness equipment that is normally found in a gym

213782. （2022•西安三中•高二上期中） Hundreds of millions have rolled up their sleeves for the COVID-19 vaccine，but why haven't they rolled up their pants instead？What's the science behind why we get most vaccines in our arm？
   Most vaccines are given in the muscle—this is known as an intramuscular injection （肌肉注射）.Some vaccines，are given orally.Others are given just beneath the skin.
   But why is the muscle so important，and does location matter？
   Muscles make an excellent vaccine administration （药物的施用） site because muscle tissue contains important immune cells.These immune cells recognize the antigen（抗原），a tiny piece of a virus or bacteria introduced by the vaccine that stimulates an immune response.In the case of the COVID-19 vaccine the immune cells in the muscle tissue pick up these antigens and present them to the lymph nodes（淋巴结）.Injecting the vaccine into muscle tissue keeps the vaccine localized，allowing immune cells to sound the alarm to other immune cells and get to work.Once a vaccine is recognized by the immune cells in the muscle，these cells carry the antigen to lymph vessels，which transport the antigen-carrying immune cells into the lymph nodes.Lymph nodes，important parts of our immune system，contain more immune cells that recognize the antigens in vaccines and start the immune process of creating antibodies.
   Muscle tissue also tends to keep vaccine reactions localized.Injecting a vaccine into the deltoid （三角肌） muscle may result in local inflammation（发炎） or soreness at the injection site.If certain vaccines are injected into fat issue，the chance of painful redness or swelling increases because fat tissue has poor blood supply，leading to poor absorption of some vaccine components.
   Yet another deciding factor in vaccine administration location is the size of the muscle.Adults and children aged three and older tend to receive vaccines in their upper arm in the deltoid.Younger children receive their vaccines mid-thigh（大腿） because their arm muscles are smaller and less developed.
   Another consideration during vaccine administration is convenience and patient acceptability.Can you imagine taking down your pants at a clinic with strangers around？Rolling up your sleeve is much easier and more preferred.

（1）How many reasons are mentioned for the vaccines given in the muscle？
A．2.
B．3.
C．4.
D．5.
（2）Why do muscles make a good vaccine administration site？
A．Muscles can easily recognize bacteria.
B．Muscle tissue stimulates immune responses.
C．Muscle tissue contains vital immune cells.
D．Muscles can prevent reproduction of viruses.
（3）What could be a result of injecting vaccines into fat issues？
A．Poor blood supply.
B．Better absorption.
C．Rapid fat loss.
D．Local pain.
（4）Where is the passage most likely taken from？
A．An advertisement.
B．A journal.
C．A speech.
D．A novel.
