A 教材同步单元练习 一、阅读理解 Passage 1 Body Positivity or Health Hazard?The Debate on Weight and Well-being In recent years,the body positivity"movement has gained widespread attention,encouraging people to accept their bodies regardless of shape or size.While this message has helped many individuals combat harmful beauty standards,a growing number of health experts wam that an uncritical embrace of all body types may inadvertently discourage healthy behaviors. Researchers from the University of Califomia surveyed over 2,000 adolescents aged 13-18.They found that teens who strongly identified with body positivity messages were less likely to engage in extreme dieting or express dissatisfaction with their bodies-a clear benefit.However,the same group also showed a 15%lower likelihood of participating in regular physical activity and a 10%higher tendency to consume fast food weekly.Dr.Linda Harper,the lead author,explains:"When we tell young people that every body is beautiful,some may interpret that as permission to ignore health guidelines altogether.The key is to promote acceptance without abandoning responsibility for one's well-being." The study highlights a delicate balance.On one hand,relentless media pressure to be thin has fueled eating disorders and low self-esteem.On the other hand,an overweight lifestyle carries serious health risks,including diabetes,heart disease,and joint problems.The challenge,according to psychologists,is to teach young people that self-love and health-consciousness are not mutually exclusive."You can cherish your body exactly as it is while still stiving to nourish it with good food and exercise,"says Dr. Harper. Critics of the study argue that body positivity has been misinterpreted.They point out that the movement's original aim was to challenge discrimination against fat people,not to promote unhealthy habits. Nevertheless,the findings suggest that educators and parents need to offer more nuanced guidance-one that celebrates diversity but also emphasizes the long-term value of a balanced lifestyle. ()1.What is the main pupose of the body positivity movement? A.To encourage people to lose weight. B.To help people appreciate their bodies regardless of size C.To promote regular physical activity. D.To discourage fast food consumption. ()2.What did the University of California study find about teens who strongly identified with body positivity？ A.They were more likely to exercise regularly. B.They were less satisfied with their bodies. C.They showed a higher tendency to eat healthy food D.They engaged in less physical activity and ate more fast food. ()3.The phrase "mutually exclusive"in paragraph 3 most probably means. A.the same in nature B.dependent on each other C.not able to exist together D.equally important ()4.What is Dr.Harper's suggested approach? A.To accept all body types without any health advice. B.To combine self-acceptance with healthy habits. C.To focus only on physical activity D.To ignore the body positivity movement. ()5.What can be inferred from the last paragraph? A.Body positivity is completely harmful. B.The study's findings are widely accepted. C.Fat discrimination is still a serious issue D.The movement's original goals have been lost. Passage 2 Exercise:The Brain's Best Friend A growing body of research is revealing that regular physical activity does more than keep the body fit- it dramatically improves brain function,especially in adolescents and young adults.A study published in the Joumal of Cognitive Neuroscience followed 350 teenagers over three years,measuring their aerobic fitness and cognitive performance. The results were striking:teens who engaged in at least 60 minutes of moderate-to-vigorous exercise daily scored significantly higher on tests of memory,attention,and problem-solving than their less active peers. Brain scans showed that the active group had larger volumes of gray matter in the hippocampus,a region critical for learning and memory."Exercise triggers the release of a protein called BDNF,which acts like fertilizer for brain cells,"explains lead researcher Dr.Emily Zhang."It helps neurons grow and form new connections..” The benefits extend beyond academics.Another experiment found that a single 20-minute biisk walk can reduce anxiety and improve mood for up to two hours.For students struggling with stress,even short bursts of exercise can serve as a powerful coping strategy."We're not saying everyone needs to run a marathon,"says Dr.Zhang."But incorporating movement into your daily routine-whether it's walking to school,dancing,or playing a sport-can have profound effects on both mental and physical health." Despite these findings,many teenagers worldwide fail to meet the recommended activity levels.The World Health Organization reports that 80%of adolescents aged 11-17 are insufficiently active,a figure that has barely changed in the last decade.Factors such as screen time,academic pressure,and lack of safe spaces contribute to this trend.Schools and communities are now exploring ways to integrate more movement into the school day,such as active classrooms where students stand or use balance balls. In an era ofincreasing anxiety and sedentary lifestyles,the message is clear:moving your body is one of the most effective ways to move your mind. ()1.What was the main finding of the study in the Journal of Cognitive Neuroscience? A.Exercise only benefits the body. B.Active teens performed better in cognitive tests. C.Gray matter decreases with exercise. D.Adolescents need less than 60 minutes of activity. ()2.How does exercise improve brain function according to Dr.Zhang? A.By reducing the size of the hippocampus. B.By releasing a protein that helps brain cells grow C.By increasing stress levels. D.By decreasing blood flow. ()3.What is the purpose of the example ofa 20-minute brisk walk? A.To show that long exercise is necessary. B.To indicate that even short exercise can improve mood. C.To compare walking with running D.To suggest that only walking is effective. ()4.Which of the following is NOT mentioned as a reason for insufficient activity among teens? A.Screen time B.Academic pressure. C.Lack of safe spaces. D.Lack of interest in sports ()5.What is the author's attitude toward exercise? A.Critical B.Neutral. C.Supportive. D.Doubtful. 二、完形填空 I used to stare at the mirror every moming,picking out every flaw.My thigh were too big,my stomach wasn't flat enough.At 15,I was (1) by the images of perfect bodies on social media.I decided to(2) -I would skip breakfast and eat only an apple for lunch.At fust,I felt powerful.But soon,I started feeling (3) and dizzy.One day during PE class,I(4) on the running track.The school nurse told me my blood sugar was dangerously low."You are (5) your health for a number on the scale,"she said gently. That night,I did some research.I learned that(6) meals doesn't make you lose weight in a healthy way-it slows down your metabolism and can damage your heart.What's more,the "perfect bodies"I saw online were often edited or achieved through(7) measures.I realized I needed to change my(⑧) towards food and exercise.Instead of starving,I started eating balanced meals and joined the school swim team.Within months,I had more energy and my mood(9) The weight came off slowly,but it stayed off.More importantly,I began to see myself differently.The mirror no longer felt like an enemy,but a(10) 1.A.inspired B.confused C.obsessed D.fiightened 2.A.act B.relax C.ignore D.hesitate 3.A.energetic B.weak C.excited D.confident 4.A.fell B.pretended C.succeeded D.cheered 5.A.improving B.risking C.protecting D.sharing 6.A.skipping B.cooking C.enjoying D.preparing 7.A.healthy B.moderate C.extreme D.safe 8.A.attitude B.identity C.appearance D.schedule 9.A.worsened B.stayed C.improved D.disappeared 10.A.joke B.tool C.challenge D.mirror 三、阅读短文回答问题 Social media platforms such as Instagram,TikTok,and Snapchat have become an integral part of teenagers'daily lives.While they offer opportunities for connection and self-expression,a growing number of studies link heavy social media use to negative body image,particularly among adolescent girls A study conducted by the University of Pittsburgh tracked 1,765 teenagers aged 14-18 over two years Participants reported how much time they spent on social media and rated their satisfaction with their bodies.The results showed that those who spent more than three hours daily on social media were twice as likely to report dissatisfaction with their appearance compared to those who used it for less than an hour.The researchers identified two main reasons:the prevalence of idealized"images-photos that are heavily edited or show only the most flattering angles-and the tendency to compare oneself to peers and influencers. Interestingly,the type of content also matters.Teens who followed fitness influencers focused on health and strength reported higher body satisfaction than those who followed accounts promoting extreme thinness."It's not all bad,"says lead researcher Dr.Maria Chen."If you follow body-positive content or educational pages about nutition,social media can actually improve your relationship with your body. But the algorithm often pushes sensational,unrealistic images because they get more engagement." Schools are beginning to respond.Some incorporate digital literacy lessons that teach students how to identify edited photos and understand the business behind influencers.Others encourage students to curate their feeds to include diverse body types and positive messages.Psychologists advise parents to have open conversations with their children about social media's impact."The goal is not to ban social media,but to help teens develop a critical eye,"says Dr.Chen.When they can see behind the filter,they are less likely to feel inadequate." 1.What was the finding of the University of Pittsburgh study regarding social media use and body satisfaction? 2.According to the passage,what two factors contribute to negative body image on social media? 3.Why might following fitness influencers focused on health be better than following accounts promoting thinness? 4.What is one suggestion from the passage that schools can do to help? 5.What is the overall advice from psychologists to parents? 四、短文填空 Many teenagers are so(1) about their weight that they try dangerous methods.For example, (2) meals can make you feel (3) and even cause you to (4) from hunger. Such practices not only fail to help you(5) down but also have a negative (6) on your health. Instead,experts suggest focusing on (7) rather than cutting calories.Eating a balanced (8) provides the energy your body needs to (9) properly.If you find it hard to (10) on your studies,check your eating habits-low blood sugar can (11) to be a major cause oftiredness.A (12) change-like having a proper breakfast-can make a big difference. Take action (13) and choose health over appearance. 1. 2. 3. 4. 5 6. 7. 8. 9. 10. 11. 12. 13. 五、写作 Suppose you are Li Hua.Your fiiend Tom has been skipping meals to lose weight and now looks tired and pale.Write him a letter (about 120-150 words)to explain the dangers ofunhealthy dieting and offer practical suggestions for a healthier lifestyle. 1.词数120-150； 2.可适当增加细节，使行文连贯； 3.开头和结尾已给出，不计入总词数。 Dear Tom, I'm writing to express my concem about your recent dieting habits.

Instead,I suggest you adopt a balanced diet rich in nutrition,including vegetables,fruits,whole grains, and lean protein.Regular exercise,like jogging or swimming,will help you build a healthy body shape and boost your energy.Remember,true beauty comes from being healthy and happy,not from a number on the scale.
