Are African wild dogs really dogs? What’s the difference between African wild dogs and the dogs we know as pets? For one thing, African wild dogs, which live in Africa, only have four toes, while domestic (驯养的) dogs and wolves have five. But you won’t want to count for yourself, because they are truly wild animals. “Wild dogs are not somebody’s domestic dogs that ran away and didn’t come back, although some people used to think that,” explains Dr. McNutt, who studies these animals at Wild Dog Research Camp in the African country of Botswana. “They are actually Africa’s wolves, and just like wolves, they do not make good pets. They need to be out in the wild doing what they are supposed to do — find the food they need to survive and feed their babies.” In fact, they travel so far that researchers have to use radio collars (颈圈) to keep track of them. The collars send out radio signals that tell people where the dogs are. No two wild dogs have the same pattern of coats, so it is easy to tell them apart. African wild dogs are smart and sociable, like pet dogs. Adult dogs, male and female, are willing to take good care of young ones. Millions of domestic dogs live on the planet, but there are probably fewer than 6,000 African wild dogs left. Humans hunt them and farmers who don’t want them to go after cows and sheep poison them. Humans are also destroying the wild, natural habitat (栖息地) they need to survive in. Fortunately, today more farmers are finding other ways to protect their cows and sheep from African wild dogs instead of killing the animals. 1.Which of the following can explain why African wild dogs are different from domestic dogs? A. African dogs can live longer than domestic dogs. B. African dogs have fewer toes than domestic dogs. C. African dogs are much bigger in size than domestic dogs. D. African dogs are much more dangerous than domestic dogs. 2.In Dr. McNutt’s view, African wild dogs . A. are a kind of wolves B. can be trained as pet dogs C. actually are missing domestic dogs D. generally are not used to living in groups 3.What’s the researchers’ purpose of using radio collars? A. To know where African wild dogs go. B. To play games with African wild dogs. C. To tell African wild dogs apart from other dogs. D. To prevent African wild dogs from traveling too far. 4.What suggestion does the author give in the last paragraph? A. Farmers should use domestic dogs to fight against wild dogs. B. African wild dogs should be protected instead of being killed. C. Farmers should take responsibility for feeding African wild dogs. D. African wild dogs should be used to protect farmers’ cows and sheep. 5.Which of the following can be used as the title of the passage? A. How to keep wild dogs B. How to train domestic dogs C. An introduction to African wild dogs D. Differences between domestic dogs and wild dogs

There are plenty of people in the UK for whom even Basic English is a problem. According to the survey, 726,000 people in England and Wales said they could not speak English well, and another 138,000 said they did not speak it at all. Ling, 40, who arrived five years ago from China,, found it difficult to learn English. “After I came here, I was at home for the next three years. It took me longer to learn as I was very busy with my children.” Eventually she was able to begin taking classes and now speaks good conversational English. But even with classes, it can be a long process to pick up the language. Age is the most important factor in language study, said Mila Vulchanova, professor of linguistics (语言学) at the Norwegian University of Science and Technology. “There is a key time in language learning, which is biologically determined. So the younger the immigrants(移民)， the better. Since this decline is only gradual, teenagers are at an advantage over adults,”he said. There are a number of systems for grading English. The government expects immigrants to reach “ESOL Entry 3”or “B1 level” in Scotland, before they can be given citizenship. It means to be able to hold a confident conversation and it might take 360 hours of study to achieve. George Osborne, the UK chancellor(财政大臣)，said in June that benefit claimants (申请救济金者) who don’t speak English will have their benefits cut if they fail to attend language courses. Huan Japes, deputy chief executive of English UK, a trade body for language colleges, said it needed 360 hours-----120 hours for each of three stages ---- to get to the result the government expected benefit claimants to reach. “Using 120 hours, for each stage of English fluency(流利)，is a rather traditional way to course book learning,” said Dr Elaine Boyd, head of English language at Trinity College London. “If someone is really highly motivated, they can learn really quickly. It’s common for children under the age of 11 to be fluent in about six months.” 1.The first paragraph serves as a(n) _______. A. introduction B. discussion C. explanation D. conclusion 2.What does Mila Vulchanova mainly stress? A. The importance of key teaching ways. B. The necessity of working hard at English. C. The advantages of learning English. D. The importance of starting learning English early. 3.The UK government hopes that benefit claimants ______. A. reach “ESOL Entry 1”. B. are advanced English learners. C. study English for about 360 hours. D. get citizenship from the government first. 4.What Dr Elaine Boyd said suggested that _____. A. 120 hours is a high level for learners. B. one can learn English fast if active. C. English fluency can be easily achieved. D. children under 11 learn English hard.

New research helps to explain why screaming is disturbing and useful. Screams, like those we hear in horror movies, have a special quality that separates them from other noises we make and hear. These screams are recognized by people all over the world. 1."Every kid in every culture screams. Every adult in the context of a true fear responds with screams. So it's just a feature of the human mind and brain．” David Poeppel is a neuroscientist at New York University. He wondered why screams were recognized the same way by people all around the world. So, he and his colleagues set up an experiment. They recorded screams from movies and from volunteers who took part in the research.2.Instead, they measured how quickly the sounds in the scream changed in volume. It was in this area-the change in volume that screams stand apart from other sounds. When the volume of a sound changes that quickly it has a quality called roughness. "3.David Poeppel and his team found that car alarms, sirens, and alarm clocks also have this quality, this roughness.” The scientists then studied how this "roughness" changed brain activity. They asked the volunteers to listen to different types of screams and alarms in an MRI scanner, The researchers found that the greater "roughness" of a sound. the more it activates the amygdala. 4.“The amygdala acts like a gauge that says ‘wow, this sound has a lot of roughness in it; that’s particularly alarming and scary. ’" Screams, it turns out, are a direct link to the part of our brain that tells us whether we should be afraid or not. 5. Now, we know why a scream.. gets so much attention, So quickly. A. People who hear these rough sounds are also more likely to react to them very quickly. B. People of all cultures and languages hear the same thing in a scream: fear. C. A scream is to say ‘I’m in trouble and I need help.’ D. The amygdala is an area deep in the brain that answers to fear. E. The more roughness a sound has, the more worrying it is F. Screams played a very important evolutionary role in our survival G. The scientists, however, did not measure the screams for loudness or pitch

In his 1930 essay "Economic Possibilities for our Grandchildren". John Keynes. a famous economist, wrote that human needs fall into two classes: absolute needs, which are independent of what others have, and relative needs. which make us feel superior to our fellows．He thought that although relative needs may indeed be insatiable（无法满足的), this is not true of absolute needs。 Keynes was surely correct that only a small Part of total spending is decided by the desire for superiority. He was greatly mistaken, however, in seeing this desire as the only source of insatiable demands. Decisions to spend are also driven by ideas of quality which can influence the demands for almost all goods, including even basic goods like food. When a couple goes out for an anniversary dinner, for example, the thought of feeling superior to others probably never comes to them. Their goal is to share a special meal that stands out from other meals. There are no obvious limits to the escalation of demand for quality. For example, Porsche, a famous car producer, has a model which was considered perhaps the best sport car on the market. Priced at over ＄ 120,000. it handles perfectly well and has great speed acceleration. But in 2001. the producer introduced some changes which made the model slightly better in handling and acceleration. People who really care about cars find these small improvements exciting. To get them, however. they must pay almost four times the price. By placing the desire to be superior to others at the heart of his description of insatiable demands, Keynes actually reduced such demands. However, the desire for higher quality has no natural limits. 1.According to the passage, John Keynes believed that______. A. desire is the root of both absolute and relative needs B. absolute needs come from or sense of superiority C. relative needs alone lead to insatiable demands D. absolute needs are stronger than relative needs 2.What do we know about the couple in Paragraph 3? A. They want to show their superiority. B. They find specialty important to meals C. Their demands for food are not easily satisfied D. Their choice of dinner is related to ideas of quality. 3.what does the underlined word" escalation" in Paragraph 4 probably mean? A. Understanding. B. Increase C. Difference. D. Study 4.The author of the passage argues that______. A. absolute needs have no limits B. demands for quality are not insatiable C. human desires influence ideas of quality D. relative needs decide most of our spending

Next week California will try to take cell phones from the hands of drivers, telling everyone from millionaires to workers that conversations behind the wheel must be on an earphone. Californians interviewed by Reuters mostly supported the law requiring hands-free phones in cars and banning cell phones entirely for drivers under 18, which will take effect on Tuesday, though they were puzzled by a loophole(漏洞) that allows seemingly more dangerous text messaging. Some were doubtful about lawmakers, who they blamed for failing to build more freeways or public transportation in the face of increasingly crowded roads in the nations most populous state and said hands-free conversations were not safer. KFI-AM radio talk-show host John Kobylt told Reuters. “It's stupid because we’ve one over about seven different studies and each one of them says it s the conversation that distracts you, not holding the phone.” State Senator Joe Simitian, who introduced the bill, said keeping both hands on the wheel was always safer. He expected his law to save hundreds of lives. The Democratic lawmaker was considering introducing a new law to ban text messaging in the car. which he said wasn’t an issue when he began working on the first one in 2001. Connecticut, New Jersey and New York have already banned drivers from talking on hand-held cell phones. In New Jersey, police have issued 35.000 tickets for using a hand-held phone or texting while driving since the law went into effect on March 1. But Californians interviewed by Reuters expressed ambivalence."On the one hand I don’t want to see people crash into each other, but I'm not going to get an ear thing.” 38-year-old bank employee Jason Fischer said in Los Angeles. 1.We can infer from Paragraph 2 that______. A. most Californians hate to use an earphone while making a call in the car B. public transportation in California isn’t developed enough C. in New Jersey few people use a hand-held phone D. most of Californians are probably against the new law 2.According to John Kobylt，_________. A. all the lawmakers are stupid B. holding the phone is safer than using an earphone C. it isn’t dangerous to make a phone call while drivin D. it is the phone conversation while driving that is really dangerous 3.What will State Senator Joe Simitian probably do in the future A. He will sup suggest a law to forbid text messaging while riving B. He will conduct a new survey among Californians C. He will suggest building more roads in California D. He will suggest a law to completely ban cell phones while driving. 4.The underlined word "ambivalence" in the last paragraph probably refers to______. A. a positive attitude B. a negative attitude C. a confused feeling D. an excited feeling
