A nutrient-rich diet with few added sugars may slow rates of biological aging in women,research suggests.Scientists found that middle-aged women who ate more foods packed with vitamins,minerals and antioxidants (抗氧化物) had “younger-looking” cells than those who had less healthy diets.They judged whether a cell was young by looking at methyl (甲基) groups on the surface of DNA.
The pattern of these methyl groups changes as we age,which is believed to increase cellular aging.“Sugars are linked to worsened health and early disease possibly more than any other food factor,” co-author Elissa Epel,a professor at the University of California,said in a statement.
Epel and her colleagues analysed food records of 342 women over three days.The team then scored each woman’s diet based on how closely it followed various established diets:While nutrient-rich diets were tied to slowed aging,added sugars seemed to control the effect.In the study,women who consumed higher amounts of added sugars showed signs of faster cellular aging compared to others,even if they ate other healthy diets.“Added sugars” refer to sugars that are added to food during production such as those in sugared drinks and baked goods,as opposed to the naturally occurring sugars found in milk,fruit and vegetables.The new study is one of the first to demonstrate a link between added sugar consumption and cellular aging,the authors said.
The team calculated the participants’ ages by looking at the DNA methylation of cells with samples.These data showed the links between diet and cellular aging,but they were only a tip of the iceberg.In fact,more research is needed to assess how following these diets might affect aging in the long run.
(　　)1.What can we learn from the study
A.A balanced diet is linked to people’s health.
B.A low-sugar healthy diet may delay women’s aging.
C.The sugary foods have no effect on women’s bodies.
D.The added sugars slow down people’s biological aging.
(　　)2.Which of the following food may make cells age faster according to Paragraph 3
A.Pure milk.
B.Chinese cabbage.
C.Birthday cakes.
D.Fresh watermelons.
(　　)3.How did Epel and her colleagues conduct their study
A.By giving an example.
B.By introducing a concept.
C.By making a comparison.
D.By raising some questions.
(　　)4.What can be inferred from the last paragraph
A.The study lacks further support.
B.There are data errors in the study.
C.People’s ages can be changed by diets.
D.Sugary diets affect health in the long run.

　　Roughly 42% of Americans are nearsighted today,compared with about 25% in 1971.The World Health Organisation predicts that about half of the world’s population will have nearsightedness by 2050.It’s apparent that our eyesight is becoming increasingly poor,but researchers are only now beginning to understand why.
Generally a childhood phenomenon,nearsightedness happens when the eyeball grows too long from front to back,taking on more of an oval (椭圆形) shape rather than a sphere (球形).Eyes have a “stop signal” so that they grow consistent with the head,explains Gregory Schwartz,an associate professor at Northwestern University.However,that signal can be interrupted by genetic and environmental factors,which leads to our eyeballs growing a bit too much,leading to far-off objects looking out of focus.Signs you might have nearsightedness also include headaches,as well as eye stress and tiredness when doing certain activities such as driving or playing sports.
The increased use of screens,most of which are high contrast,like black text on a white page,or light text on a dark background,overstimulating our eyes,causing more eye growth in children and less time spent outdoors are to blame.A 2017 study found a connection between increased natural light exposure and a decrease in nearsightedness,particularly in children and young adults.Exposure to natural light stimulates dopamine,a chemical which helps regulate normal growth and development of the eyeball.Indoor lighting doesn’t do the trick.
Most people’s vision will stabilise in their teens,but some people develop nearsightedness later in life,typically between ages 20 and 40.Poor eyesight isn’t the only downside; people with nearsightedness are at a higher risk of developing eye issues as they age.That’s why regular eye exercise is crucial.
(　　)1.What is the function of the figures in Paragraph 1
A.To draw the attention of WHO.
B.To introduce the research methods.
C.To explain the causes of nearsightedness.
D.To illustrate the seriousness of nearsightedness.
(　　)2.What happens to the eyeballs of nearsighted children
A.They are out of shape.
B.They match the growth of heads.
C.They grow into a sphere.
D.They distinguish far-off objects easily.
(　　)3.What is the main idea of Paragraph 3
A.The overuse of screens.
B.The benefits of protecting eyes.
C.The causes of nearsightedness.
D.The influence of exposure to light.
(　　)4.What might the author continue talking about
A.Eye issues of aging.
B.Key factors to affect eyesight.
C.The ways to exercise eyes.
D.The downside of nearsightedness.
语篇导读:本文是说明文。文章指出近视率上升的严峻现状,解释近视成因(眼球变形、遗传因素和环境因素的影响、屏幕使用多等),提及近视的危害,强调定期做眼保健操的重要性。
答案及剖析:
1.D　推理判断题。第一段前两句给出两组关键数据——1971年美国近视率约为25%,如今已约达42%。世界卫生组织预测2050年全球约一半人口将近视。这些数据直观展现了近视人群比例大幅上升、范围持续扩大的趋势,核心作用是凸显近视问题的严重性。故选D。
2.A　细节理解题。第二段第一句明确指出,近视发生时眼球前后径过长,呈现椭圆形而非球形。椭圆形与正常的球形对比,说明近视儿童的眼球形态异常,这是近视的核心生理特征。故选A。
3.C　段落大意题。第三段第一句直接点明近视的两大诱因——屏幕使用增加和户外活动时间减少。随后通过2017年的研究进一步补充说明自然光照射不足会降低多巴胺分泌,影响眼球正常发育。整段内容围绕导致近视的具体环境因素展开,核心主旨是分析近视的成因。故选C。
4.C　推理判断题。根据最后一段最后一句可知,作者在结尾强调了眼保健操的重要性,由此可推断接下来可能会介绍做眼保健操的方法。故选C。
Ⅳ.语法填空(共10题;每题1.5分,共15分)
By now we have heard this advice countless times:It is important 1.　　　　 (wash) your hands often and thoroughly.Actually typical hand-washing guidelines advise washing your hands for at least 20 seconds.

They confirm that 20 seconds 9.　　　　 (be) the minimum time of an 10.　　　　 (effect) hand-washing to remove germs,without taking the use of soap into account.They hope understanding the mechanisms of washing hands may help lead to more environmentally friendly soaps.
语篇导读:本文是说明文。文章阐述了洗手时需要搓洗至少20秒的原因。
答案及剖析:
1.to wash　考查动词不定式。句中it为形式主语,此处应用动词不定式作真正的主语。故填to wash。
2.which/that　考查定语从句。分析句子结构可知,设空处在句中引导定语从句,修饰前面的名词hands,从句中缺少主语,先行词为物,应用关系代词which或that引导。故填which/that。

4.are trapped　考查动词的时态、语态和主谓一致。主语Some harmful particles与trap构成被动关系,故此处应用被动语态;结合上下文可知,本文是在陈述一般事实,应用一般现在时,故此处应用一般现在时的被动语态,且主语表示复数概念。故填are trapped。
5.stronger　考查形容词比较级。设空处在句中修饰名词flow,应用形容词形式;结合后面的more easily可知,此处应用形容词的比较级。故填stronger。
6.with　考查固定搭配。“have something in common with...”为固定短语,意为“在某方面与……有共同之处”,此处用介词with。故填with。
7.if　考查状语从句。根据句意可知,此处表示“如果手搓得太慢、太轻”,前半句是后半句实现的条件,此处是一个条件状语从句,应用if引导。故填if。
8.gently　考查副词。设空处在句中与前面的slowly并列修饰动词move,作状语,应用副词形式。故填gently。
9.is　考查主谓一致。设空处在that引导的宾语从句中作谓语,结合上下文可知,此处应用一般现在时;其主语为20 seconds,此处作为一个整体,意义上表示单数。故填is。
10.effective　考查形容词。设空处在句中修饰名词hand-washing,作定语,应用形容词形式;结合句意及提示词可知,此处应用effective,意为“有效的”。故填effective。UNIT 2　课时作业(三)

When we talk about positive thinking,we often use terms having to do with our hearts—open heart,pure heart or joyful heart.But research from Duke University is making a closer connection,finding that a positive attitude may be helpful to people who have angina (心绞痛),a common heart condition.
Symptoms of this condition include chest pain or pressure because the heart is not receiving sufficient oxygen.Patients who displayed optimistic thought patterns,including having positive expectations about recovery,were 40 percent less likely to be hospitalised or require surgery than those who were not optimistic,according to the study.The researchers collected data from 2,400 patients who had been diagnosed with angina.
An interesting additional finding from the patients’ questionnaires was that the most optimistic patients were also the least likely to have histories of heart attack,heart failure or heart disease.
The researchers did not declare a causal relationship between positive thinking and better heart disease outcomes,however.There are multiple possible reasons for the results of the study,including the idea that patients who are healthier to begin with are more likely to expect to recover and regain good health.
But the study does represent a new way of looking at the situation.Now,in addition to a body of research that examines the relationship between depression and heart health,there is a new way of inquiry that asks whether positive thinking could be used as a strategy to improve outcomes.
Lead researcher Alexander Fanaroff,a fellow in the department of cardiology (心脏病学) at the Duke University Medical Centre,told the media that his next research question would find ways to improve attitudes among heart patients.
Perhaps his subjects could reflect on the words of the writer Anthony,“Smile—it is the key that fits the lock of everybody’s heart.”
(　　)1.How can people with angina get better according to the study
A.By expecting more.
B.By thinking positively.
C.By getting timely surgery.
D.By taking more exercise.
(　　)2.What may be Alexander Fanaroff’s next research
A.To explore how to improve patients’ attitudes.
B.To find out the ways to treat heart patients.
C.To learn the causes of heart diseases.
D.To test if positive attitudes help with health.
(　　)3.What can we learn from the text
A.Optimistic people hardly get heart attack.
B.Patients’ positive attitudes ensure their recovery.
C.How positive thinking benefits heart health is unclear.
D.The reason why patients recover well is that they have no depression.
(　　)4.What may be a suitable title for the text
A.Keep Positive to Get Rid of Illness
B.Angina,a Kind of Serious Condition
C.Depression,a Key Cause of Heart Attack
D.Positive Thinking May Make Hearts Healthier
语篇导读:本文是说明文。文章介绍了一项研究,该研究表明,积极的态度可能对患有心绞痛的人有帮助。
答案及剖析:
1.B　细节理解题。根据第一段的第二句可知,杜克大学的一项研究发现,积极的态度可能对患有心绞痛的人有帮助。故选B。
2.A　细节理解题。根据倒数第二段中的“...his next research question...among heart patients.”可知,Alexander Fanaroff下一步的研究可能是探讨如何改善患者的态度。故选A。
3.C　推理判断题。根据第四段内容可知,研究人员并未声明积极的思维与更好的心脏病结果之间存在因果关系,并表明可能有多种原因导致这一研究结果。由此可推知,目前尚不清楚积极的思维如何有益于心脏健康。故选C。
4.D　标题归纳题。通读全文,尤其是根据第一段内容可知,杜克大学的研究表明,积极的态度可能有助于患有心绞痛的人恢复健康。由此可推断,D项适合作为文章的标题。故选D。UNIT 2　课时作业(二)

Pulling an all-nighter might seem like a quick fix when you’re preparing for an exam or trying to meet a deadline.1.　　
Lack of sleep significantly affects cognitive (认知的) functions.It can reduce your ability to concentrate,damage cognitive thinking,and affect decision-making abilities.2.　　　 Skipping it reduces your brain’s ability to process and remember information,making it harder to recall what you’ve studied.Lack of sleep can also do harm to your mental health.It increases emotional swings and stress levels.Individuals lacking sleep are more likely to experience anxiety and depression.
Here are some strategies to prepare for exams without all-nighters.Effective study planning is important.Break down your study material into manageable sections and spread it over several days or weeks.Active learning techniques can also make a significant difference.Use flashcards and past exams to test your knowledge.Practising testing is one of the most effective study techniques.Maintaining healthy study habits is also necessary.3.　　　 20 minutes of focused study followed by a 5-minute break can be particularly effective.Eat balanced meals to maintain energy levels.
4.　　　 Aim for 7-9 hours of sleep each night.A proper sleep schedule helps regulate your body’s internal clock,making it easier to fall asleep and wake up.Limit caffeine intake and screen time before bed.
In brief,while pulling an all-nighter might seem like a tempting solution,the negative impacts far outweigh any short-term benefits.5.　　　 It’s important to develop good sleep habits.Remember,a well-rested mind is far more capable of absorbing and memorising information,leading to better academic performance and overall well-being.
A.Engage in regular physical exercise.
B.Good sleep habits shouldn’t be overlooked.
C.These techniques can help calm your mind.
D.Take short breaks at regular intervals to avoid burnout.
E.But the results can be harmful to your mental and physical health.
F.Sleep is the most effective thing to reset our brain each day.
G.Adopting scientific strategies can help you prepare for exams more effectively.

Good morning,everyone!
Nowadays,there is a growing focus on health care.People are pursuing a healthy lifestyle,of which a healthy diet is one of the most important parts.
As the saying goes,“Bread is the staff of life.”Eating healthily and deliciously is the goal we pursue.From my point of view,in order to build healthy eating habits,we should eat more vegetables,which are rich in vitamins.Among them,vitamin C and vitamin A are very important.Too much fat and sugar can lead to obesity,which is harmful to health.Besides,eating more fruit and drinking more water are of great help.
I hope we can live a healthy life.Let’s take action.Thanks for your listening!UNIT 2　课时作业(一)

A nutrient-rich diet with few added sugars may slow rates of biological aging in women,research suggests.Scientists found that middle-aged women who ate more foods packed with vitamins,minerals and antioxidants (抗氧化物) had “younger-looking” cells than those who had less healthy diets.They judged whether a cell was young by looking at methyl (甲基) groups on the surface of DNA.
The pattern of these methyl groups changes as we age,which is believed to increase cellular aging.“Sugars are linked to worsened health and early disease possibly more than any other food factor,” co-author Elissa Epel,a professor at the University of California,said in a statement.
Epel and her colleagues analysed food records of 342 women over three days.The team then scored each woman’s diet based on how closely it followed various established diets:While nutrient-rich diets were tied to slowed aging,added sugars seemed to control the effect.In the study,women who consumed higher amounts of added sugars showed signs of faster cellular aging compared to others,even if they ate other healthy diets.“Added sugars” refer to sugars that are added to food during production such as those in sugared drinks and baked goods,as opposed to the naturally occurring sugars found in milk,fruit and vegetables.The new study is one of the first to demonstrate a link between added sugar consumption and cellular aging,the authors said.
The team calculated the participants’ ages by looking at the DNA methylation of cells with samples.These data showed the links between diet and cellular aging,but they were only a tip of the iceberg.In fact,more research is needed to assess how following these diets might affect aging in the long run.
(　　)1.What can we learn from the study
A.A balanced diet is linked to people’s health.
B.A low-sugar healthy diet may delay women’s aging.
C.The sugary foods have no effect on women’s bodies.
D.The added sugars slow down people’s biological aging.
(　　)2.Which of the following food may make cells age faster according to Paragraph 3
A.Pure milk.
B.Chinese cabbage.
C.Birthday cakes.
D.Fresh watermelons.
(　　)3.How did Epel and her colleagues conduct their study
A.By giving an example.
B.By introducing a concept.
C.By making a comparison.
D.By raising some questions.
(　　)4.What can be inferred from the last paragraph
A.The study lacks further support.
B.There are data errors in the study.
C.People’s ages can be changed by diets.
D.Sugary diets affect health in the long run.UNIT 2　课时作业(四)

Ⅱ.七选五(共5题;每题2.5分,共12.5分)
Pulling an all-nighter might seem like a quick fix when you’re preparing for an exam or trying to meet a deadline.1.　　
Lack of sleep significantly affects cognitive (认知的) functions.It can reduce your ability to concentrate,damage cognitive thinking,and affect decision-making abilities.2.　　　 Skipping it reduces your brain’s ability to process and remember information,making it harder to recall what you’ve studied.Lack of sleep can also do harm to your mental health.It increases emotional swings and stress levels.Individuals lacking sleep are more likely to experience anxiety and depression.
Here are some strategies to prepare for exams without all-nighters.Effective study planning is important.Break down your study material into manageable sections and spread it over several days or weeks.Active learning techniques can also make a significant difference.Use flashcards and past exams to test your knowledge.Practising testing is one of the most effective study techniques.Maintaining healthy study habits is also necessary.3.　　　 20 minutes of focused study followed by a 5-minute break can be particularly effective.Eat balanced meals to maintain energy levels.
4.　　　 Aim for 7-9 hours of sleep each night.A proper sleep schedule helps regulate your body’s internal clock,making it easier to fall asleep and wake up.Limit caffeine intake and screen time before bed.
In brief,while pulling an all-nighter might seem like a tempting solution,the negative impacts far outweigh any short-term benefits.5.　　　 It’s important to develop good sleep habits.Remember,a well-rested mind is far more capable of absorbing and memorising information,leading to better academic performance and overall well-being.
A.Engage in regular physical exercise.
B.Good sleep habits shouldn’t be overlooked.
C.These techniques can help calm your mind.
D.Take short breaks at regular intervals to avoid burnout.
E.But the results can be harmful to your mental and physical health.
F.Sleep is the most effective thing to reset our brain each day.
G.Adopting scientific strategies can help you prepare for exams more effectively.
语篇导读:本文是说明文。文章讲述了考前通宵的坏处及良好睡眠的重要性。
答案及剖析:
1.E　根据前文可知,通宵似乎是备考或赶截止日期的快速解决方案。后面则从“认知功能受损”“心理健康危害”等角度阐述通宵的负面影响。E项通过转折词but衔接前文,引出后文对通宵危害的具体说明,符合语境。故选E。
2.F　根据后文可知,睡眠不足会降低大脑处理和记忆信息的能力,强调睡眠对记忆力的重要性。F项直接点明睡眠的核心作用,与后面睡眠不足的危害形成“正面作用——反面结果”的对比逻辑,衔接紧密,符合语境。故选F。
3.D　本段主题是“健康的学习习惯”,根据设空处后的内容可知,“20分钟专注学习后休息5分钟非常有效”具体解释“短时休息的好处”。D项是对后一句具体休息方式的概括,符合语境。故选D。
4.B　设空处后文围绕“每晚7-9小时睡眠”“规律作息”“睡前限制咖啡因和屏幕时间”展开,核心是良好的睡眠习惯。B项作为段落总起句,直接点明主题,统领后文内容,符合语境。故选B。
5.G　前文指出“通宵的负面影响远大于短期好处”,后文强调养成良好睡眠习惯很重要,中间需衔接“替代通宵的科学方法”。G项既呼应前文“否定通宵”,又引出后文“良好习惯”,同时承接第二段“备考策略”,形成逻辑闭环,符合语境。故选G。

语篇导读:本文是记叙文。文章讲述了作者曾经不接受朋友提出的去散步的建议,直到3年前经历了低谷,作者开始坚持每天外出散步,渐渐发现这一行动对自己的身心健康产生了巨大的影响。
答案及剖析:
1.A　根据上文“In times of...going for a walk.”可知,作者的朋友建议作者在有压力和沮丧的时候外出散步,因此作者会认为这是一份善意(kindness)。故选A。
2.C　根据语境可推知,作者无法理解外出散步对应对压力和沮丧会有帮助(help)。故选C。
3.B　根据上文“Three years ago,I hit a low point.”可知,作者陷入了低谷,因此照镜子时会看见自己空洞的(empty)眼神。故选B。
4.D　根据上文可知,作者的朋友建议作者在有压力和沮丧的时候外出散步,此处指作者打算接受这条建议,advice和上文的suggest呼应。故选D。
5.B　根据上文描述的作者一开始很不相信在有压力和沮丧的时候外出散步会有帮助,但在陷入低谷的时候打算尝试散步可推知,作者此时是抱着试一试的态度,希望散步能以某种方式(somehow)改变目前低谷中的生活。故选B。
6.C　根据下文to it every single day for more than a month可推知,作者坚持(stuck)每天散步。故选C。
7.D　根据下文make it outside和but I managed to可知,此处有转折,应该是有些日子几乎不(hardly)能去外面散步。故选D。
8.A　根据语境可知,此处有转折,作者应该是克服无法外出散步的情况,坚持了下来。push through意为“完成;促成;排除困难办成好事”。故选A。
9.C　根据下文“I’m glad I took the photos”可知,作者有拍照,picture和下文的photos呼应。故选C。
10.B　根据上文描述的一开始散步的效果不佳,但作者依然坚持外出散步可推知,作者想记录自己努力尝试的过程,make an effort意为“做出努力”。故选B。
11.B　根据下文“I found myself smiling.”可知,随着时间的推移,作者发现自己在微笑,从之前的低谷中慢慢走了出来,因此是发生了不可思议的(unbelievable)事情。故选B。
12.D　根据第一段内容可知,作者一开始其实并不接受朋友提出的去散步的建议,认为这根本没用,由此可推知,作者曾经讨厌散步,hated和下文的the best part形成对比,突出散步带来的好的效果。故选D。
13.C　根据下文stopped to look at the blue skies and listened to music可知,作者散步时的心情是很轻松愉快的,因此用danced,意为“雀跃”,表示作者轻快地沿着小路移动。故选C。
14.C　根据上文可知,作者之前陷入了低谷,由此可推知,散步改善了作者的情况,让作者看起来不再那么受挫(defeated)和疲惫。故选C。
15.A　根据下文“I guess I didn’t want to believe...and mental well-being.”可知,作者在分析自己之前不愿意去散步的原因,因此此处指作者不知道自己一直拒绝(refused)这样做的原因。故
选A。

Ⅳ.阅读理解(共4题;每题2.5分,共10分)
When we talk about positive thinking,we often use terms having to do with our hearts—open heart,pure heart or joyful heart.But research from Duke University is making a closer connection,finding that a positive attitude may be helpful to people who have angina (心绞痛),a common heart condition.
Symptoms of this condition include chest pain or pressure because the heart is not receiving sufficient oxygen.Patients who displayed optimistic thought patterns,including having positive expectations about recovery,were 40 percent less likely to be hospitalised or require surgery than those who were not optimistic,according to the study.The researchers collected data from 2,400 patients who had been diagnosed with angina.
An interesting additional finding from the patients’ questionnaires was that the most optimistic patients were also the least likely to have histories of heart attack,heart failure or heart disease.
The researchers did not declare a causal relationship between positive thinking and better heart disease outcomes,however.There are multiple possible reasons for the results of the study,including the idea that patients who are healthier to begin with are more likely to expect to recover and regain good health.
But the study does represent a new way of looking at the situation.Now,in addition to a body of research that examines the relationship between depression and heart health,there is a new way of inquiry that asks whether positive thinking could be used as a strategy to improve outcomes.
Lead researcher Alexander Fanaroff,a fellow in the department of cardiology (心脏病学) at the Duke University Medical Centre,told the media that his next research question would find ways to improve attitudes among heart patients.
Perhaps his subjects could reflect on the words of the writer Anthony,“Smile—it is the key that fits the lock of everybody’s heart.”
(　　)1.How can people with angina get better according to the study
A.By expecting more.
B.By thinking positively.
C.By getting timely surgery.
D.By taking more exercise.
(　　)2.What may be Alexander Fanaroff’s next research
A.To explore how to improve patients’ attitudes.
B.To find out the ways to treat heart patients.
C.To learn the causes of heart diseases.
D.To test if positive attitudes help with health.
(　　)3.What can we learn from the text
A.Optimistic people hardly get heart attack.
B.Patients’ positive attitudes ensure their recovery.
C.How positive thinking benefits heart health is unclear.
D.The reason why patients recover well is that they have no depression.
(　　)4.What may be a suitable title for the text
A.Keep Positive to Get Rid of Illness
B.Angina,a Kind of Serious Condition
C.Depression,a Key Cause of Heart Attack
D.Positive Thinking May Make Hearts Healthier
