2019年高考英語大一輪復(fù)習 Unit 4 Sharing課時作業(yè) 新人教版選修6 Ⅰ. 閱讀理解 A (xx吉安模擬) Clothes can make phone calls, play music, dial your pal’s number, keep you warm during cold weather and operate your puter. This is not a fantasy. A British pany, called Electrotextiles, has created a wide range of clothes—clothes that have minds of their own! Scientists, working for the pany, have invented a kind of fabric that can be blended(混合)with flexible electronic materials to create intelligent clothing. The result is electronic garments. If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100 percent shock proof, they say. The Electrotextiles team has also created the world’s first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These“l(fā)ap-tap”gadgets(器具)are all set to take over laptop puters! Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat fortably with others at the wheel! Other popular electronic wear includes the denim(牛仔布)jacket with flexible earphones sewn into the hood(風帽)and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids. Having pleted the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a puter mouse. What is the next? Do you have any idea? 【文章大意】本文是一篇科技說明文。主要介紹了一些高科技的布料、衣服等, 這些新發(fā)明有各種各樣的功能, 比如打電話、聽歌。 1. The electronic garments are similar to other electronic devices in that　　　.

Robert Wayne of the University of California, Los Angeles, and Jennifer Leonard of the Smithsonian Institute, used DNA material—some of it unearthed by miners in Alaska—to conclude that today’s domestic dog originated in Asia and acpanied the first humans to the New World about 10, 000 to 15, 000 years ago. Wayne suggests that man’s best friend may have enabled the tough journey from Asia into North America. “Dogs may have been the reason people made it across the land bridge, ”said Wayne. “They can pull things, carry things, defend you from fierce animals, and they’re useful to eat. ” Researchers have agreed that today’s dog is the result of the domestication(馴化)of wolves thousands of years ago. Before this recent study, a mon thought about the precise origin of North America’s domestic dog was that Natives domesticated local wolves, the descendants(后代)of which now live with people in Alaska, Canada, and the Lower 48. Dog remains from a Fairbanks-area gold mine helped the scientists reach their conclusion. Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost(永凍層)until Fairbanks miners uncovered them in the 1920s. The miners donated the preserved bones to the American Museum of Natural History in New York City, where they remained untouched for more than 70 years. After borrowing the bones from the museum, Leonard and her colleagues used radiocarbon techniques to find the age of the Alaska dogs. They found the dogs all lived between the years of 1450 and 1675 A. D. , before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. “The bones of dogs that wandered the Fairbanks area centuries ago should therefore be the remains of pure native American dogs, ”Leonard said. The DNA of the Fairbanks dogs would also expose whether they were the descendants of wolves from North America. Along with the Fairbanks samples, the researchers collected DNA from bones of 37 dog specimens(標本)from Mexico, Peru, and Bolivia that existed before the arrival of Columbus. In the case of both the Alaska dogs and the dogs from Latin America, the researchers found that they shared the most genetic material with gray wolves of Europe and Asia. This supports the idea of domestic dogs entering the New World with the first human explorers who wandered east over the land bridge. Leonard and Wayne’s study suggests that dogs joined the first humans that made the adventure across the Bering Land Bridge to slowly populate the Americas. Wayne thinks the dogs that made the trip must have provided some excellent service to their human panions or they would not have been brought along. “Dogs must have been useful because they were expensive to keep, ”Wayne said. “They didn’t feed on mice; they fed on meat, which was a very guarded resource. ” 【文章大意】本文是科普性文章。說明了在幾千年前狗陪同人們一起跨過白令大陸橋進入北美大陸, 并且在此繁殖起來。而通過檢測發(fā)掘出的狗骨頭的DNA也證實了這一點。 5. The underlined word“remains”is closest in meaning to“　　　”. A. leftover food　　　　　 B. animal waste C. dead bodies D. living environment 【解析】選C。詞義猜測題。根據(jù)第四段第二句話“Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost”說明是在永凍層發(fā)現(xiàn)的狗的骨頭, 所以remains應(yīng)該是尸體。故C正確。 6. According to the study described in Paragraph 4, we can learn that　　　. A. ancient dogs entered North America between 1450 and 1675 A. D. B. the 11 bones of ancient dogs are not from native American dogs C. the bones discovered by the gold miners were from North American wolves D. the bones studied were not from dogs brought into North America by Europeans 【解析】選D。細節(jié)理解題。根據(jù)“They found the dogs all lived between the years of 1450 and 1675 A. D. , before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. . . ”可判斷出被研究的骨頭不是歐洲人帶到北美的狗的骨頭。所以D正確。 7. What can we know from the passage? A. Native Americans domesticated local wolves into dogs. B. Scientists discovered some ancient dog remains in the 1920s. C. Latin America’s dogs are different from North America’s in genes. D. Ancient dogs entered North America across the Bering Land Bridge. 【解析】選D。細節(jié)理解題。根據(jù)第一段“When people first walked across the Bering Land Bridge thousands of years ago, dogs were by their sides, according to a study published in the journal Science. ”可知D正確。 8. What does the passage mainly talk about? A. The origin of the North American dogs. B. The DNA study of ancient dogs in America. C. The reasons why early people entered America. D. The difference between Asian and American dogs. 【解析】選A。推理判斷題。文章第一段提到狗和人們一同跨過the Bering Land Bridge, 第二、三、四、五段研究狗的DNA“to conclude that today’s domestic dog originated in Asia”, “Researchers have agreed that today’s dog is the result of the domestication of wolves thousands of years ago”, 所以文章中心是談?wù)摫泵赖墓返钠鹪础? Ⅱ. 閱讀第二節(jié) (xx哈爾濱模擬) 　　　1　People traveled in search of food and shelter or in order to flee from their enemies. Sometimes they were looking for gold or silver in order to bee rich.
