If you want to improve your child"s results at school, you could do a lot worse than ensuring that they do plenty of exercise.Scientists have already shown that physical activity can make you brainier.But a team in America has used scans to show that an important part of the brain actually grows in children who are fit.These youngsters tend to be more intelligent and have better memories than those who are inactive. Scientists also found that one of the most important parts of their brains was 12 percent larger than those of unfit children.They believe that encouraging children to take exercise from a very young age could help them do better at school later.Researchers from the University of Illinois, in the U.S., studied the brains of 49 children aged nine and ten using a magnetic resonance imaging scan (核磁共振 摄影扫描), a technique which provides very detailed pictures of organs and tissues in the body. They also tested the fitness levels of the children by making them run on a treadmill (跑步机).The scientists found that the hippocampus, a part of the brain responsible for memory and learning, was around 12 percent larger in the fitter children. Professor Art Kramer, who led the study published in the journal Brain Research, said the findings had important implications for encouraging individuals to take part in sport from a young age."We knew that experience and environmental factors and socioeconomic status all impact brain development," he said. "If you get some terrible genes from your parents, you can"t really fix that, and it"s not easy to do something about your economic status.But here"s something that we can do something about." |

阅读理解 Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings. The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves. Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect. Some scientists have suggested setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales. A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales" ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed(流血)and become infected (感染). Many researchers whose work depends on ocean sounds are against a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect(怀疑)that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean. 1. According to the passage, which of the following is increasingly dangerous to sea creatures? A. The noises of human activities. B. The noises made by themselves. C. The sound of earthquakes. D. The sound of the ice-breaking. 2. Which of the following is discussed in the third paragraph? A. Different places with different types of noises. B. The very human ears sensitive to all types of noises. C. The same noise measured differently on land and in the ocean. D. The ocean animals" reaction to noises. 3. According to the passage, what will scientists most probably do in the future? A. They will try their best to decrease noise. B. They will work hard to cut down noise pollution. C. They will study the effect of different noises. D. They will protect animals from harmful noises. |

Last year college students in America spent an estimated $700 on textbooks on average. The National Association of College Stores reported more than five billion dollars in sales of textbooks and course materials. The association spokesman Charles Schmidt says electronic textbooks now just make up 2%~3% of sales. But he says that is expected to reach 10%~15% by 2012. Online versions(版本) are now available for many of the most popular college textbooks. An etextbook can cost half the price of a new print textbook.But students usually lose access to them after the end of the term.And the books cannot be placed on more than one device(设备), so they are not easy to share. So what do students think of etextbooks?Administrators at Northwest Missouri State University wanted to find it out.Earlier this year they tested them with 500 students in 20 classes. The university is unusual.It provides laptop computers for all 7,000 of its fulltime students.It does not require students to buy their textbooks either.They rent them to save money.The school aims to save even more by moving to etextbooks. The students in the survey reported that downloading the books from the Internet was easy.They liked the idea of carrying lighter backpacks.And 56% said they were better able to find information. But most found that using etextbooks did not change their study habits.And 60% felt they read more when they were reading on paper.In all, almost half the students said they still liked physical textbooks better. But the survey found that cost could be a big influence.55% said they would choose etextbooks if using them meant their textbook rental fee would not increase. Roger Von Holzen heads the Center for Information Technology in Education at Northwest Missouri State University.He tells us that administrators are disappointed with the etextbooks now available because the majority are not interactive(交互式的). He thinks growth will come when more digital books include video, activities, games and other ways to interact with the information.The technology is improving.But for now, most of the books are just words on a screen.
1. Etextbooks are not better than paper books in that________.
A. they cost more money B. they"re difficult to carry C. they"re not convenient to share D. they can"t be downloaded from the Internet
2. How many surveyed students think paper books make better reading?
A. 60%. B. 56%. C. 55%. D. 50%.
3. It can be inferred from the text that in the future________.
A. digital books will be more popular B. the digital books available need improvement C. free digital books are available online D. digital books will replace print textbooks |
阅读理解 Today, innovations(创新) to make our lives more eco-friendly can be found everywhere. There are energy-efficient automobiles, eco-friendly light bulbs, and clothes made by fashion designers using sustainable(可持续的) environmental practices. Industries around the world have also begun to take a serious look at how their operations affect the local and global environment. The university of Colorado has been named one of the top green colleges and universities in the United States. This university was one of the first to start a student-led recycling program in the 1970s and today supplies students with reusable shopping bags to use both on and off campus. The entire University of Colorado also uses low flow water fixtures(设备) and has reduced water usage by 40 percent since 2002. When it comes to going green, Warren Wilson College has been recognized in many places. The Sierra Club and The Princeton Review have named the college as one of America"s greenest colleges and universities, while the school has also received the Outstanding College Recycling Award from the Carolina Recycling Association, as well as awards from the Association for the Advancement of Sustainability in Higher Education(AASHE). For a small college, Warren Wilson has made enormous efforts to be an eco-friendly campus since its beginning, and today owns a campus farm, a seeding program, and an extensive recycling program. Warren Wilson was also the first College to have an LEED platinum certified(白金认证的) residence hall, and its building services department is also 100 percent GreenSeal certified. According to College Stats, Warren Wilson College is one of the first institutions in the United States to be almost completely self-sufficient(自给自足的) while also engaging students to incorporate sustainability into all academic programs. Going green efforts at Oberlin College have not gone unnoticed. Oberlin College spends 22 percent of its food budget on buying food from local farmers, with most of the food raised or harvested with organic and sustainable practices. Oberlin has also stopped selling bottled water on campus and offers discounts to students who use their own storage containers when purchasing beverages and food items. Among Oberlin"s other eco-friendly accomplishments is a green graduation ceremony, which includes programs printed on 100 percent recycled paper. 1.The author writes the first paragraph mainly to tell us that ____. A. we can find new ways to be eco-friendly B. everyone is aware of being eco-friendly C. industries are reducing their influence on the environment D. American colleges and universities care much about environmental issues 2.What do we know about the University of Colorado? A. Its recycling program is followed by other universities. B. It produces reusable shopping bags by itself. C. It uses special systems to save water. D. It is the most eco-friendly university. 3.Which of the following about Warren Wilson College is TRUE? A. The Princeton Review praised it for its teaching methods. B. Its residence hall"s building material is platinum. C. It owns a campus garden and a seeding program. D. It sustains itself almost without help from others. 4.Students in Oberlin College can _____. A. grow their own food on campus B. pay less with their own containers C. help the college make its food budget D. recycle paper at their graduation ceremony 5.How is the text organized? A.

What do working mothers worry about the most? It"s the kids of course. Whatever the setting, the question I get asked the most is "Will the kids be alright?" It"s made me realize that we tend to look at the glass half-empty rather than half-filled when it comes to mixing work and family. We forget about all the benefits that we bring to our children when we work - and I"m not talking about the obvious financial benefits, although these of course shouldn"t be taken for granted. About a year ago I remember getting a call from the school just as I was pulling up to the house after having driven 20 minutes to the school and 20 minutes back. "Mrs. Brown Quinn, your son asked us to call. He forgot his sports clothes. Can you come back to the school and drop them off?" I was exasperated(恼火)! I had already spent 40 minutes in aggressive weekday morning traffic. I replied, "Sorry, I"m working at the moment. I"m afraid my son needs to learn to be organized." Being a good parent requires delivering tough love sometimes. Kids need to learn to be independent. It can be a cruel and competitive world out there. Seeking interests, including business, outside of your kids, can give you that extra idea that you need not care for your kids with attention. This benefit of working isn"t always immediately evident. It wasn"t until our daughter went away to college that she realized why we had raised her in the way that we did. "Mom, I can"t believe how so many of my friends struggle to manage things on their own. They are constantly calling their parents for help." You"ll love that moment! After all those years of complaining about why you don"t do this or why you don"t give them that, your kids realize that tough love has made them better people.
1. The author refused to drop off her son"s sports clothes because ______.
A. she was caught in heavy traffic B. she was busy working C. she thought her son was lying D. she wanted her son to be organized
2. How can kids become better people according to the author?
A. By giving them all your attention. B. By giving them freedom to do things on their own. C. By showing them your deep love. D. By giving them tough love.
3. The daughter"s attitude towards the author is ______ when she grows up.
A. surprised B. caring C. understanding D. disappointed
4. The purpose of the author is to ______.
A. throw light on a special benefit of working B. advise us to mix work and family C. argue for working mothers D. describe her own experience in raising children |
