　　2017西安市高考英语三轮冲刺选练1 阅读理解。 (2017·绍兴统考)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. 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 accompanied 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(驯化)of wolves thousands of years ago. Before this recent study, a common 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(永冻层)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(标本)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 companions 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。说明了在几千年前狗陪同人们一起跨过白令大陆桥进入北美大陆, 并且在此繁殖起来。而通过检测发掘出的狗骨头的DNA也证实了这一点。 1. The underlined word“remains”is closest in meaning to“　”. A. leftover food　B. animal waste C. dead bodies D. living environment 【解析】选C。词义猜测题。根据第四段第二句话“Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost”说明是在永冻层发现的狗的骨头, 所以remains应该是尸体。故C正确。 . 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】选D。细节理解题。根据“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. . . ”可判断出被研究的骨头不是欧洲人带到北美的狗的骨头。所以D正确。 . 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】选D。细节理解题。根据第一段“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正确。 4. 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】选A。推理判断题。文章第一段提到狗和人们一同跨过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”, 所以文章中心是谈论北美的狗的起源。 (1) The United States became a rich industrial nation toward the end of 1800s. There were more goods, more services, more jobs, and a higher standard of living. There was more of everything, including problems. One problem was monopoly, that is, to be the only seller of a certain line of products or a service. In some cases, several companies that manufactured the same product would agree not to compete with one another. They would all agree to charge the same price. These arrangements made it impossible for customers to shop around for lower prices for certain products. Some people decided that huge corporations had too much power and controlled too many markets. Because of their wealth and power, they could see to it that governments passed laws favorable to them. Many people believed that monopoly and price fixing were bad for customers and bad for the country so that they should be broken up. Finally the national government and some states passed laws that placed limits on corporations and big companies. These laws made it illegal for companies to make agreements to charge only a certain price. Later on the national government forced monopoly to be broken up. Such laws and government action didn’t entirely do away with monopolies. Nor did they stop the growth of huge corporations. But they did show that American people had decided that some of the changes that had occurred were harmful. (from www.nmet168.com) 1. The underlined word “monopoly” in the first paragraph most probably means ________. A. the production of certain kinds of goods B. complete control and possession of trade C. a big corporation of company D. an agreement on prices 2.

Which of the following is not true according to the passage? A. Big companies could not influence the government. B. A large number of markets were controlled by big companies. C. Many Americans were worried about the changes in their country. D. Some of the laws were in favor of customers. 1. B 词义猜测题。根据该词之后的解析句“to be the only seller of a certain line of products or a service”可猜测出其意义。 2. C 细节理解题。根据第一段最后一句“These arrangements made it impossible for customers to shop around for lower prices for certain products”分析可知 3. A 细节理解题。根据第三段中的“These laws made it illegal for companies to make agreements to charge only a certain price”一句可知。 4. A 事实确认题。第二段“Because of their wealth and power, they could see to it that governments passed laws favorable to them”一句的意义是：因为拥有财富和势力，他们能确保政府通过有利于他们的法律。由此可确认“大公司对政府是有影响力的”。 （2017安徽卷）为了帮助中学生健康成长，某中学英文报开辟了“HEART-TO-HEART”专栏。假设你是该栏目的编辑Jamie，收到一封署名为Worried的求助信。信中该同学向你诉说了自己的困扰：近日容易发脾气，使正常的学习和生活受到了影响。请用英文给该同学写一封回信。内容要点如下： 1．表示理解并给予安慰； 2．提出建议并说明理由。注意： 1．词数120左右； 2．信中不能出现与本人相关的信息； 3．信的开头与结尾已为你拟好，不计入总词数。参考词汇：temper n. 脾气，情绪 Hi Worried， I’m sorry to know that you’re having such a had time at the moment.
