It was a scene that had been repeated many times in the theater’s 75-year history. This time, however, the cleanup was a little different. As one group of workers carried out the rubbish, another group began removing seats and other theater equipment in preparation for the building’s end.‎ The film classic The Last Picture Show was the last movie shown in the old theater. Though the movie is 30 years old, most of the 250 seats were filled with teary-eyed audience wanting to say good-be to the old building. Theater owner Ed Bradford said he chose the movie because it seemed appropriate. The movie is set in a small town where the only movie theater is preparing to close down.‎ Bradford said that large modern theaters in the city made it impossible for the Plaza to compete. He added that the theater’s location(位置) was also a reason. “This used to be the center of town,” he said. “Now the area is mostly office buildings and warehouses.”‎ Last week some city officials suggested the city might be interested in turning the old theater into a museum and public meeting place. However, these plans were abandoned because of financial problems. Bradford sold the building and land to a local development firm, which plans to build a shopping complex on the land where the theater is located.‎ The theater audience said good-by as Bradford locked the doors for the last time. After 75 years the Plaza Theater has shown its last movie. The theater will be missed.‎ ‎24. In what way was yesterday’s cleanup at the Plaza special?‎ A. It made room for new equipment.‎ B. It signaled the closedown of the theater.‎ C. It was done with the help of the audience.‎ D. It marked the 75th anniversary of the theater.‎ ‎25. Why was The Last Picture Show put on?‎ A. It was an all-time classic. B. It was about the history of the town.‎ C. The audience requested it. D. The theater owner found it suitable.‎ ‎26. What will probably happen to the building?‎ A. It will be repaired. B. It will be turned into a museum.‎ C. It will be knocked down. D. It will be sold to the city government. ‎ ‎27. What can we infer about the audience?‎ A. They are disappointed with Bradford. B. They are sad to part with the old theater. ‎ C. They are supportive of the city officials. D. They are eager to have a shopping center. ‎ ‎【解析】本文是一篇记叙文，讲述了一家具有75年历史的剧院因为不利的地理位置和现代剧院的竞争，而面临着不得不关门，转手出售的故事。‎ ‎11.【2017·新课标III】C After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.‎ Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared ‎ from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.‎ The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf – grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’ s red foxes, and completely drove away the park’ s beavers.[来源:学科网]‎ As early as 1966,biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.‎ The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone.Elk, deer, and coyote populations are down, while beavers and red fores have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.‎ ‎28.What is the text mainly about?‎ A. Wildlife research in the United States.‎ B. Plant diversity in the Yellowstone area.‎ C. The conflict between farmers and gray wolves.‎ D. The reintroduction of wolves to Yellowstone Park.‎ ‎29.What does the underlined word “displaced” in paragraph 2 mean?‎ A. Tested. B. Separated. C. Forced out. D. Tracked down.‎ ‎30.What did the disappearance of gray wolves bring about？‎ A. Damage to local ecology. B. A decline in the park’s income.‎ C. Preservation of vegetation. D. An increase in the variety of animals.‎ ‎31.What is the author’s attitude towards the Yellowstone wolf project？‎ A. Doubtful. B. Positive. C. Disapproving. D. Uncaring.‎ ‎【文章大意】本文是一篇说明文，介绍了美国黄石公园重新引进灰狼的事情。因为人类活动影响到灰狼数量逐渐减少，鹿群数量逐渐增加，从而造成植被遭到大量破坏。‎ ‎30．细节理解题。根据第三段内容可知，灰狼的减少造成了鹿群的增多，从而植被遭到了破坏；而且红狐和海狸也不断减少，由此推断灰狼的消失引起了当地生态的破坏。故选A。‎ ‎31．推理判断题。根据文章末段末句可知，作者认为引进灰狼的项目是很有价值的实验，是很值得推广的。可知作者对黄石公园引进灰狼的态度是”积极的，赞成的“，故选B。‎ ‎12.【2017·新课标III】D The Intelligent Transport team at Newcastle University have turned an electric car into a mobile laboratory named “DriveLAB” in order to understand the challenges faced by older drivers and to discover where the key stress points are.‎ Research shows that giving up driving is one of the key reasons for a fall in health and well-being among older people, leading to them becoming more isolated(隔绝) and inactive.‎ Led by Professor Phil Blythe, the Newcastle team are developing in-vehicle technologies for older drivers which they hope could help them to continue driving into later life.‎ These include custom-made navigation(导航) tools, night vision systems and intelligent speed adaptations. Phil Blythe explains: “For many older people, particularly those living alone or in the country, driving is important for preserving their independence, giving them the freedom to get out and about without having to rely on others.”‎ ‎ “But we all have to accept that as we get older our reactions slow down and this often results in people avoiding any potentially challenging driving conditions and losing confidence in their driving skills. The result is that people stop driving before they really need to.”‎ Dr Amy Guo, the leading researcher on the older driver study, explains, “The DriveLAB is helping us to understand what the key points and difficulties are for older drivers and how we might use technology to address these problems. “For example, most of us would expect older drivers always go slower than everyone else but surprisingly, we found that in 30mph zones they struggled to keep at a constant speed and so were more likely to break the speed limit and be at risk of getting fined. We’re looking at the benefits of systems which control their speed as a way of preventing that.‎ ‎ “We hope that our work will help with technological solutions(解决方案) to ensure that older drivers stay safer behind the wheel.”‎ ‎32.What is the purpose of the Drivel AB?‎ A.To explore newmeans of transport.‎ B.To design new types of cars.‎ C.To find out older driver`s problems.‎ D.To teach people traffic rules.‎ ‎33.Why is driving important for older people according to Phil Blythe?‎ A.It keeps them independent.‎ B.It helps them save time.‎ C.It builds up their strength.‎ D.It cures their mental illnesses.‎ ‎34.What do researchers hope to do for older drivers?‎ A.Improve their driving skills.‎ B.Develop driver-assist technologles.‎ C.Provide tips on repairing their cars.‎ D.Organize regular physical checkups.‎ ‎35.What is the best title for the text?‎ A.A new Model Electric Car B.A Solution to Traffic Problem C.Driving Service for elders D.Keeping Older Drivers on the Road ‎【解析】本文主要介绍了老年司机在需要停止开车的年龄之前就不得不停止开车，所以一些研究人员就开始了解老年司机存在的问题，想要用技术去解决这些问题，比如发开了控制速度的系统、制定导航工具、夜视系统和智能速度适应。‎ ‎33.

The girls on the Wesleyan Academy softball were waiting for their next turns at bat during practice, stamping their feet to stay warm, Eighth-grader Taylor Bisbee shivered(发抖) a little as she watched her teammate Paris White ‎ play. The two didn’t know each other well — Taylor had just moved to town a month or so before.‎ Suddenly, Paris fell to the ground,“Paris’s eye rolled back,” Taylor says. “She started shaking. I knew it was an emergency.”‎ It certainly was, Paris had suffered a sudden heart failure. Without immediate medical care, Paris would die. At first no one moved. The girls were in shock. Then the softball coach shouted out, “Does anyone know CPR?”‎ CPR is a life-saving technique. To do CPR, you press on the sick person’s chest so that blood moves through the body and takes oxygen to organs. Without oxygen the brain is damaging quickly.‎ Amazingly, Taylor had just taken a CPR course the day before. Still, she hesitated. She didn’t think she knew it well enough. But when no one else came forward, Taylor ran to Paris and began doing CPR, “It was scary. I knew it was the difference between life and death,” says Taylor.‎ Taylor’s swift action helped her teammates calm down. One girl called 911. Two more ran to get the school nurse, who brought a defibrillator, an electronic devices(器械) that can shock the heart back into work. Luck stayed with them: Paris’ heartbeat returned.‎ ‎“I know I was really lucky,” Paris says now. “Most people don’t survive this. My team saved my life.”‎ Experts say Paris is right: For a sudden heart failure, the single best chance for survival is having someone nearby step in and do CPR quickly.‎ Today, Paris is back on the softball team. Taylor will apply to college soon. She wants to be a nurse. “I feel more confident in my actions now,” Taylor says. “I know I can act under pressure in a scary situation.”‎ ‎56.What happened to Paris on a March day?‎ A. She caught a bad cold.‎ B. She had a sudden heart problem.‎ C. She was knocked down by a ball.‎ D. She shivered terribly during practice ‎57.Why does Paris say she was lucky?‎ A. She made a worthy friend.‎ B. She recovered from shock.‎ C. She received immediate CPR.‎ D. She came back on the softball team.‎ ‎58.Which of the following words can best describe Taylor?‎ A. Enthusiastic and kind.‎ B. Courageous and calm.‎ C. Cooperative and generous.‎ D. Ambitious and professional.‎ ‎【解析】本文是一篇记叙文，讲述了垒球队一名女孩Paris在打球的过程中突发心力衰竭，队友Taylor紧急对Paris进行了心肺复苏，送往医院后她恢复了心跳的故事，旨在说明面临心力衰竭时，保持冷静并进行紧急心肺复苏的重要性。‎ ‎56．根据第三段第一行，“It certainly was。 Paris had suffered a sudden heart failure。”可知，Paris突发心脏病，故B项正确。‎
