This was the best time of day to drive, when the roads were wide open and empty. He felt sure he was going to make it to Los Angeles before midnight. It looked like it was going to be a good day.Then he saw it, a large lump in the middle of the road. Daryl often passed dead animals on the roadside but he knew that this was something different. He slammed on his brakes and the truck screeched to a halt.The lump was a girl. He tried shaking her awake but she wouldn’t move, so he picked her up and carried her to the side of the road. At least she wouldn’t be run over the re.Now she was someone else’s problem. He had to make it to Los Angeles by midnight and didn’t have time to be a hero. He climbed back into his truck but as he looked in his mirror and saw the girl lying still by the side of the road, he knew he couldn’t leave her. Daryl put her into his truck and drove to the next town.An hour later he pulled up at the police station. After explaining what had happened, he prepared to leave, only for the policeman to say that he needed to make a report. Daryl knew this would take several hours, but he had no choice. There was no way he’d get to Los Angeles on time now.Three hours later the report was done and the girl had recovered somewhat. She explained that she had fallen on the highway, weak from hunger, but could remember nothing else. Shealso thanked Daryl for saving her life. Daryl told her that he had been happy to help, but as he got back into his truck he knew his boss wouldn’t be.Just as he was about to pull back onto the road, his mother called. “Have you seen？” she said. “A bridge collapsed two hours ago, the one that you drive over on the way to Los Angeles.”Daryl’s blood ran cold. If he had been on time, he would have been on that fallen bridge about two hours ago. Daryl realized how lucky he was.24. What did Daryl plan to do in Los Angeles？A. Go on holiday.B.

When and w here dogs first began living side-by-side with humans are questions that have stirred hot debate among scientists. There are a few hard facts that all agree on. These include that dogs were once wolves and they were the first animal to be domesticated （驯养） by humans. They came into our lives some 15,000 years ago, before the dawn of agriculture.Beyond that, there is little agreement. The earliest bones found that are unquestionable dogs and not wolves date from 14,000 years ago. However, 30,000-year-old skulls have been discovered in France and Belgium that are not pure wolf and some scientists think could be dogs.With such puzzling evidence, many scientists are now turning to DNA to find out when and where dogs were first domesticated. In one research project, tens of thousands of blood samples have been taken from street dogs around the world. The plan is to compare them with those of wolves. It’s even possible to analyse DNA from ancient bones. Tiny pieces of the30,000-year-old skulls mentioned earlier are currently being studied, and another DNA study has already shown that ancient dogs preserved in the Alaskan ice-fields evolved from Asian wolves, not American ones.Indeed, the ancient DNA may turn out to be more informative than the DNA of living dogs. Because dogs have accompanied humans around the world for thousands of years, their current distribution may tell us very little of their origins. This is why different groups of scientists believe that dogs variously originated in eastern Asia, Mongolia, Siberia, Europe or Africa.But why were the animals domesticated in the first place？ The most recent theory is that dogs domesticated themselves, initially living in and around our ancient villages to eat any food thrown out. Today, this is a way of life still shared by three-quarters of a billion unowned dogs worldwide.28. Which is the only statement generally agreed on by scientists studying dogs？A. They originally were used as farm animal.B. They evolved from wolves found in Europe.C. They helped the development of agriculture.D. They were the first animal to be kept as pets.29. Why does the writer first mention the 30,000-year-old-animal skulls？A. To show that dogs were much larger in the past.B. To prove that dogs developed from Asian wolves.C. To suggest that dogs may have evolved much earlier.D. To argue that dogs were first kept in France and Belgium.30. How did scientists determine the origins of the ancient dogs found in Alaska？A. By examining t he animals’ DNA.B. By analyzing the age of their bones.C. By studying the shape of their skulls.D. By comparing them with modern dogs.31. Why did dogs start living with humans？A. Because they were attracted by food.B. Because they were trapped by humans.C. Because they couldn’t survive in the wild.D. Because they were trained to protect villages.DMany people believe that the only way to make our communities saf er is to build more prisons. But there’s a way to better protect cities and towns by doing just the opposite.In many countries throughout the world, prison populations have risen dramatically over the past decade. One of the main reasons for this is the large number of repeat offenders; that is people who break the law again once freed from jail. Statistics show that about one in four prisoners freed every year return to jail within three years.This is partly because ex-prisoners face huge difficulty finding employment. More than a third of them cannot find any job at all. Data show that having a job greatly reduc es the chances that a person will commit a c rime again or commit one in the first place. Releasedprisoners who do manage to find steady employment are 50 percent less likely to return to prison. Rather than harming a community, having a job helps ex-prisoners to change their ways and make a positive and productive contribution to their community.What’s more, helping these men and women find jobs would also save taxpayers a lot of money. Fewer prisoners would save governments millions or possibly even billions of dollars annually：the costs of building and operating jails.There are many things that the government can do to help ex-prisoners find work. More job training programs should be introduced to provide prisoners with work skills before they are freed. Companies and factories should also be given tax benefits if they employ ex-prisoners. Such programs have been shown to work in several countries.Such policies of course assume that freed c riminals actually want to work. But shouldn’t they be given the chance？Our goal, after all, shouldn’t be to incarcerate as many criminals as possible, but to build a society that doesn’t need to put such a large percentage of its population in jail. We should take a step in that direction and help prisoners find self-respect and purpose through work.32. What percentage of freed prisoners return to prison within three years？A. 65%.B. 50%.C. 33%.D. 25%.33. Which of the following best describes the content of the fifth paragraph？A. Facts.B. Arguments.C. Recommendations.D. Requirements.34. What does the underlined word “incarcerate” in the last paragraph mean？A. set freeB. lock upC. employD. separate35. Which of the following would the author agree with？A. Tougher punishment will reduce crime.B. Most prisoners do not deserve to be in prison.C. Economic conditions are a major cause of crime.D. Prison populations are likely to increase in the future.第二节（共5小题，每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
