单元测试Ⅰ. 阅读理解（共15小题；每小题2.5分，满分37.5分）AIn the United States, 30 percent of the adult population has a “weight problem”. To many people, the cause is clear: we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. In fact, some investigations（调查）, such as a 1970 study of 3,545 London office workers, report that, on balance, fat people eat less than slimmer people.Studies show that slim people are more active than fat people. A study by a research group at Stanford University School of Medicine found the following interesting facts. The more the men ran, the greater loss of body fat. The more they ran, the greater their increase in food intake（吸收）. Thus, those who ran the most ate the most, yet lost greatest amount of body fat.1. Based on the statistics given in the article, suppose there are 500 adult Americans, about how many of them will have weight problems?A. 30.B. 50.C. 100.D. 150.2. In comparison with the adult American population today, the Americans of 1910 ________.A. ate more food and had more physical activitiesB. ate less food but had more activitiesC. ate less food and had less physical exercisesD. had more weight problems3. What has modern medical and scientific research reported to us?A. Fat people eat less food and are less active.B. Fat people eat more food than thin people and are more active.C. Fat people eat more food than thin people but are less active.D. Thin people run less, and need less food to eat.BWe live in a world where it’s often not easy to find someone to trust. A smiling person always inspires trust. Even economists consider that smiles are valuable. A smile may increase other people’s trust by about 10%.People may also smile when they are caught doing bad things. According to a study made by LaFrance and Hecht, this can in fact be to their own advantage. We have a tendency to be kinder towards those who make mistakes if they wear a smile while being caught. Even a guilty smile may help you get away pretty easily when you make mistakes.We may also smile when we hear a piece of good news. In this case, women tend to smile more often than men. Smiling can also be a means of reducing the pain caused by a troubling situation. Even if we force ourselves to smile when we don’t want to, this may be enough to lift our spirits just a little bit.When we feel angry or anxious, our attention tends to narrow down. We can no longer see what’s going on around us and we can only notice what is in front of us. But if we smile, we feel better and increase flexibility of our attention and the ability to think. Smiling can help us focus and understand better.“Keep on smiling, and the world will smile with you.” One of the greatest social pleasure is to smile and be smiled to in return, especially because this comes like a natural thing.People who smile often live longer. A study based on some pictures taken of some baseball players suggested that those who used to smile a lot survived about 7 years longer than those who did not smile very often.4. The passage mainly talks about ________.A. the benefits of smilingB. the occasions when you smileC. the ways of smilingD. the reasons why people smile5. When caught doing bad things, people smile to ________.A. admit their mistakesB. show they are excitedC. avoid blame or punishmentD. prove they are kind6. According to the third paragraph, we can learn that ________.A. men seldom smile at a piece of good newsB. smiles can be helpful whatever the situation isC. we should force ourselves to smile whenever it isD. in general, men are more likely to smile than women7. The underlined sentence in the fifth paragraph probably means ________.A. if we smile, it is hard to be smiled toB. if we smile, others will smile to us in returnC. if we want to smile, the world will smile to us in timeD. if we smile sometimes, we will make the world full of smilesCPilates, yoga and the running machine get all the attention when it comes to popular ways to stay healthy. There is, however, a more humble exercise that might not be so attractive, but has all the benefits — walking.Certified fitness professional Jolynn Jaekel explains, “What I love about walking is that anyone can do it at any age and any fitness level. Plus, it is good for your heart, your head and your wallet.”A recent report details the health benefits of walking. The report found that walking regularly to fulfill the 150 minutes of moderate physical exercise every week, recommended by the UK’s chief medical officer, could save 37,000 lives each year. Scientists at the Lawrence Berkeley National Laboratory in California found that quick walking reduces the risk of heart disease more effectively than running. They observed participants aged between 18 and 80 over a six-year period and found that walking reduced the risk of heart disease by 9.3%, while running reduced it by 4.5%. And there is even more good news: 30 minutes of quick walking over five days could help you sleep easily, according to research by Oregon State University. The study by the university showed that walking helped participants sleep better and feel more alert during the day. The sooner you get started, the sooner you’ll notice the differences in your mind and body. So, go out for your 30-minute walk in a nearby park or green space.8. The underlined word “humble” in the first paragraph probably means “________”.A. plainB. relaxingC. popularD. active9. What does Jolynn Jaekel think of walking?A. It’s loved by people of all ages.B. It’s much healthier than running.C. It’s a moneysaving physical exercise.D. It’s becoming more and more popular.10. What did scientists at the Lawrence Berkeley National Laboratory find?A. Walking helps people with sleep problems.B. Walking contributes to curing heart disease.C. Walking 150 minutes per week can save lives.D. Walking is better than running in some cases.11. In which section of a newspaper can we read this text?A. Comment.B. Lifestyle.C. Education.D. Science.DOnce upon a time, when you first attended a youth sporting event, your parents probably weren’t expecting you to become a professional athlete. They signed up for a basketball, football or swimming course for you in the hope that you might learn lessons about winning gentlemanly, losing with dignity（尊严）and insisting on it when things get hard. Yes, playing games is good exercise, but it is the life lessons that matter most.For many of us, instead of looking to improve our minds and spirits, we began judging progress only by the size of our muscles or the numbers on a weighing machine. The thought that athletic competition is about greater life lessons and the building of character has been further undermined（削弱）by headlines about professional athletes.“And yet there’s still strong evidence that sports strongly improve certain personal qualities,” says Angela Lumpkin, Professor of the Department of Health, Sport and Exercise Sciences at the University of Kansas. And that’s true for athletes of any age. Amateur sports（业余体育运动）provide a safe place for competition. They also provide a practice ground for managing stress.The advantages of taking part in a sport can seep（渗透）into your professional life, too. In basketball, for example, “Getting everyone to play the right role on the court is the key to success,” says Alan Arlt, the founder of the Life Time Fitness basketball program Ultimate Hoops. “That is certainly useful in the business world, where everyone understands their own role in the organization.” In athletic events, you go through good and bad times often in the period of two hours,” says former NBA head coach Flip Saunders. “Do you have the calm manner to settle yourself down, or do you totally lose it and get thrown out of the game which hurts both you and your team? All of that on-court experience has a real effect on how you deal with real-life situations.”12. What would parents expect when their children joined in sports?A. To win as many games as possible.B. To improve their health.C. To make more friends.D. To get through difficulties.13. What can we learn from Paragraph 2?A. People play sports to build their character.B. People still hold the idea that sports can keep us fit.C. People keep playing sports to improve minds and spirits.D. People pay more attention to the news of professional athletes.14. Amateur sports are mentioned in Paragraph 3 in order to ________.A. support Lumpkin’s ideaB. introduce the next topicC. show another piece of evidenceD. show the main idea of the paragraph15. According to the last paragraph, the sports experience has a real effect on ________.A. how to succeed in the futureB. how to keep calm in certain situationsC. how to deal with reallife situationsD. how to understand the role on the courtⅡ. 阅读，七选五（共5小题；每小题2.5分，满分12.5分）All of us know that a balanced diet strengthens the immune system. 16 . The following strategies will help you to jump-start healthy eating habits.Morning must-havesResearchers at Harvard Medical School discovered that people who took daily breakfast were a third less likely to become obese（肥胖的）than those who skipped this meal.
