ADo you ever do homework while listening to music, or watch TV while texting friend? It may seem like an obvious question since most of us multitask(做多个任务) all the time.But according to a recent study published in the journal PLOS ONE, using a number of media devices(媒体设备) at the same time could be changing our brains.The report was carried out by Sussex University in the UK. Researchers first asked 75 adults about how often they spent time multitasking between different kinds of media. Then they checked their brains with an MRI machine. Those who reported heavier media multitasking had less gray matter in their brains. Gray matter is the part of the brain that helps to deal with information and control emotions(情感).So is multitasking really rotting our brains and making us stupid? We can’t be sure, according to researchers.They say that the results only show a link. They are unsure whether multitasking reduces gray matter or if people with less gray matter are simply more likely to multitask.“Media multitasking is becoming more popular in our lives today and there is increasing concern about its influence(影响) on our well-being,” said British scientist Kep Kee Loh, who directed the study.Loh says that more study is needed to support the idea that our behaviors are changing our brains. But if it’s true, it could support earlier studies about media multitasking.In 2012, a study by Michigan State University in the US found that people using several media devices at the same time were more likely to be anxious or depressed.It seems that more research into the issue is needed. But no matter what, you should consider limiting(限制) yourself to one screen at a time, the Huffington Post reported.For one thing ,Multitasking doesn’t actually work if you are trying to be more efficient(有效率的). You’re going from one action to another instead of truly doing two things at a time. It wastes your energy and slows you down. And once you’ve slowed down, it can be hard to pick back up where you left off.If you want to finish a list of jobs, “set goals, establish a routine(常规), and take regular breaks”, suggested The Huffington Post.1. What did the recent study by Sussex University find?A. Most people have the ability to multitask.B. Multitasking can help to improve efficiency.C. There are several reasons behind media multitasking.D. There is a link between more media multitasking and less grey matter.2. The underlined word “rotting” is closest in meaning to _____.A. harmingB. controllingC. improvingD. recovering3. Which of the following is TRUE according to the article?A. Many studies have proven that people’s behaviors change their brains.B. Scientists are concerned about the bad influence of media multitasking.C. Depressed people use more media devices than other people to relieve stress.D. People are advised to stop using media devices in the future.BModern zoos are very different from zoos built fifty years ago. At that time, zoos were places where people could go to see animals from many parts of the world. The animals lived in cages with iron bars, which were easy to keep clean. However, for the animals, the cages were small and impossible to hide in. Although the zoo keepers took good care of them, many of the animals did not feel comfortable, and they often became ill.In modern zoos, people can see animals in more natural conditions. The animals are given more freedom in larger places so that they can live more as they would in nature. Even the appearance of zoos has changed. Trees and grass grow in the cages, and water flows through the places that the animals live in. There are few bars; instead, there is often a deep ditch filled with water, which surrounds a space where several sorts of animals live together as they would naturally. In an American zoo, the visitor can walk through a huge special cage that is filled with trees, some small animals and many birds, and the cage is large enough for the birds to live naturally. In a zoo in New York, because of special night, people can observe certain animals that are active only at night, when most zoos are closed. Some zoos have special places for visitors to watch animals that live in the desert, or under water. Some other zoos have special places for animals that live in cold conditions like the bear from the Arctic.Modern zoos not only show animals for visitors, but also keep and save rare animals. For this reason, fifty years from now, the grandchildren of today's visitors will still be able to enjoy watching these animals.4. Fifty years ago, animals in zoos often became ill because they ________.A. were from different countriesB. lived in dirty cagesC. were not taken good care ofD. lived in unnatural conditions5. According to the passage, in modern zoos ________ feel more comfortable than in old ones.A. the animals, not the visitorsB. the visitors, not the animalsC. neither the animals nor the visitorsD. the animals and the visitors6 The main idea of this passage is that ________.A. zoos are now places where animals can live naturallyB. zoos are places where people can see animals from all over the worldC. there are different kinds of modern zoosD. rare animals are also kept in modern zoos二完形填空（共20小题；每小题1.5分，满分30分）阅读下面的短文，从短文后各题所给的四个选项（A、B、C和D）中，选出可以填入空白处的最佳选项，并在答题卡上将该项涂黑。
