There was no school there and he had to study in a school in the town. It was nearly five kilometers away from his village. His father couldn’t buy a bike for him and he had to go to school on foot. He got up early in the morning. Usually he had to run there in order not to miss the first class. He kept running every day and it was helpful to him. He’s strong and tall now and he runs faster than any other man in his village. He took part in several sports meetings and won some medals. The young man is proud of it and always wants to have a race with others.‎ One day his mother was ill and his father told him to buy some medicine for headache in the town. The young man got there soon. There were many people in the chemist’s shop while he was waiting there. And when his turn came, he couldn’t find his money. An old woman hinted(暗示) a young man had stolen it. He saw the thief had already left the shop. He ran towards him quickly. The thief found it and began to run. He was happy and tried to catch up with him.‎ ‎“Let’s have a race and see who will run faster,” Ruben called out behind.‎ Soon after that he caught up with the thief. But the didn’t stop and went on running. At a crossing one of his friend asked. ‎ ‎“What are you running for, Ruben?”‎ ‎“I’m running after(追) a thief.”‎ ‎“Where’s the thief, then?”‎ ‎“He wants to show that he’ll run faster than I , but he’s fallen behind!”‎ ‎( ) 46. ,so he won some medals.‎ A. Ruben was good at running ‎ B. Ruben went to school on time C. Ruben often took part in the sports meetings D. Ruben liked to have a race with others ‎( ) 47. The underlined phrase “chemist’s shop” in the story ‎ means .‎ A. 化工商店 B. 药店 C. 化工厂 D.制药厂 ‎( ) 48. Ruben’s money was stolen .‎ A. on his way to the town ‎ B. before he went in the shop C. when he was waiting in the shop ‎ D. after he had left the shop ‎( ) 49. Ruben was happy because .‎ A. he could easily catch the thief ‎ B. he had a chance(机会) to have a race C. he knew who had stolen his money ‎ D. he would win another medal that day B After spending three days in a wheelchair, I was ready to quit. Not only did I have to battle cracked(裂缝旳) and uneven(不平旳) pavements, I had to deal with the bad attitude of pedestrians(行人)and a cold rain. But I didn’t give up because of people like Tiffany Payne.‎ Payne, who has been using a wheelchair for 18 years, laughed at me:‎ ‎“Imagine trying to get around town in the winter,” she said.‎ I could see her point: You’re battling to get to a doctor’s appointment(预约), but no one has shoveled（铲）after a big snowfall. Your choices: Move out and risk getting stuck, or reschedule the appointment.‎ Those of us fortunate enough to get around on our own two legs don’t give a second thought to the person in a wheelchair next to us at a crosswalk. That would require us to look down.‎ So I decided to try using a wheelchair to get a sample of what their lives are like. It wasn’t long before I saw that people who use wheelchairs are forced to deal with a lot of ‎ trouble.‎ During my experiment, I was ignored by store staff while shopping and bumped into by inattentive(疏忽旳)walkers without so much as an apology. Some people even gave me angry looks as if I were the one at fault.‎ Once in a store, a woman bumped into me trying to get to the new iPad. She didn’t say, “Excuse me.”‎ When salespeople did offer assistance, they talked to people who were with me, instead of me. I wanted to yell, “Hey, I’m down here!”‎ Some salespeople talked to me as though I were a child or acted like they didn’t want to be bothered with me.‎ People who use wheelchairs want to be treated like everyone else. They also comprehend(理解), so you don’t have to speak to them in a childlike ,sing-song voice. It’s not very appealing(吸引人旳), especially when the person is an adult. And most importantly , remember they have feelings that can be hurt just like yours.‎ Spending three days in a wheelchair made me look differently at those who have to use one. I hope you do the same.‎ ‎( ) 50. The author writes the story to .‎ A. help those in wheelchairs gain self-confidence B. share his experience of acting as a wheelchair user C. ask people to show sympathy for these in wheelchairs D. call on people to respect and help those in wheelchairs ‎( ) 51. During his three days in a wheelchair, the author met all of the following difficulties EXCEPT .‎ A. bad road condition ‎ B. poor attitudes of ordinary people C. terrible medical service ‎ D. bad weather ‎( ) 52. What can we conclude from the article?‎ A. A wheelchair user may feel offended when you do not speak to him or her directly.‎ B. Assistants in big stores are usually kind to people in wheelchairs.‎ C. People in wheelchairs should fight for fair treatment.‎ D. People in wheelchairs are usually hard to get along with.‎ ‎( ) 53. Which of the following statements would the author agree to?‎ A. Look down on a person in a wheelchair.‎ B. Speak to a person in a wheelchair in a sing-song voice.‎ C. Treat a person in a wheelchair as you would treat any other person.‎ D. Offer assistance to a person in a wheelchair without asking for permission.‎ C A famous teacher was speaking to the students at our school. He began his lesson by holding up a ￥100 bill. Then he said to the three hundred students, “Who would like this ￥100 bill?” The students began to put up their hands at once.‎ Then he said, “I am going to give this ￥100 bill to one of you, but first, let me do this.” He then made the bill into a ball. Then he said, “Who wants it now?” The hands went back into the air.‎ ‎“Well,” he said, “What if I do this? “ and he dropped it on the floor and stepped on it. He picked up the dirty, crumpled bill and said, “Who still wants it?” Hands went back into the air.‎ ‎“My friends,” he said, “you have learned a valuable lesson today. No matter(无论) what I did to the money, you still wanted it because it did not go down in value(价值). It was still worth ￥100!”‎ Many times in our lives, we are dropped, crumpled, and stepped on by the chances we take and the things that happen to us. We feel as if we are worth nothing. But remember, no ‎ matter what has happened to you, you will never lose your value: you are always valuable to those people who love you. Your value doesn’t come from what you do or whom you know, but WHO YOU ARE.‎ You are special and valuable. Don’t ever forget it!‎ ‎( ) 54. Even though it was dirty, the money .‎ A. still went up in value B. was worth much C. didn’t go down in value D. was still ours ‎( ) 55. We are always valuable to the people .‎ A. who live with us B. who educate us C. who care about us D. who study with us ‎( ) 56. The underlined sentence “Hands went back into the air” ‎ means .‎ A. the students put up their hands again ‎ B. the students put down their hands C. the students agreed to what the teacher said D. the students put their hands in front of them ‎( ) 57. Why did the famous teacher use a ￥100 bill at his lesson?‎ A. Because he wanted to make the bill into a ball.‎ B. Because he used to drop a bill on the floor and step on it.‎ C. Because he was going to give the bill to one of the students.‎ D. Because he wanted to make the students know what value was.‎ D People who like traveling have their reasons. They believe that traveling can help them expand their field of view, especially in the geographical and historical sense. They also think that touring will give them more chances to enjoy different kinds of food and experience new things that would never be brought by other activities. But those who dislike traveling also have some reasons.‎ Traveling, in my opinion, does more good than harm. Most importantly, it broadens(使扩大) our mind. We can get in touch with other civilizations(文明), cultures, customs and ideas.‎ Through history, most people traveled because of necessity(必要性)-not for pleasure. People traveled just in order to remain alive. They searched for food to eat or places to live. They sometimes ran away from enemies. This is not to say that no one ever traveled just for the fun of it. In ancient times, for example, rich Romans traveled all the way to Greece to take part in the Olympic Games, and festivals. Of course, some people decided to travel just out of curiosity(好奇心). They wanted to find out what it looked like beyond the ‎ horizon(地平线). Also business travel has been going on for centuries. Traders could not only make money but also learn to speak several languages and be introduced to different cultures.‎ So, traveling does enrich our mind and draw new ideas to us. There is no doubt that we can get much from it.‎ ‎( ) 58. The underlined word “expand” in Paragraph 1 can be replaced by “ “.‎ A. widen B. protect C. lose D. decide ‎( ) 59. According to the passage, in the past most people traveled .‎ A. for fun ‎ B. for knowledge ‎ C. to get experiences ‎ D. to make a living ‎( ) 60. How many reasons for traveling are mentioned in Paragraph 3?‎ A. Three. B. Four. C. Five. D. Six.‎ 第二节 （共5小题，每小题2分，满分10分）‎ 根据短文内容，从A-F选项中选出能概括每一段主题旳最佳选项.选项中有一项为多余.‎ A. The introduction of ‎Paris B. The culture of ‎Paris C. The population growth in ‎Paris D. The production of ‎Paris E. The education in ‎Paris F. The industries in ‎Paris ‎61.‎ Paris‎, the capital and the largest city of the country, is in north central France. The Paris metropolitan area contains nearly 20% of the nation’s population and is the economic, cultural, and political center of France. The French governments have historically favored the city as the site for all decision making, thus powerfully attracting nearly all of the nation’s activities.‎ ‎62.‎ Paris‎ has grown steadily since it was chosen as the national capital in the late 10th century. With the introduction of the Industrial Revolution, a great number of people moved to the city from the country during the 19th century. The migration was especially stimulated by the construction of railroads, which provided easy access to the capital. After World War Ⅱ，more and more immigrants arrived.‎ ‎63.‎ The city is the centralized control point of most national ‎ radio and television broadcasting. It is a place of publication of the most important newspapers and magazines and an international book publishing center. With more than 100 museums, Paris has truly one of the greatest concentrations of art treasures in the world. The Louvre, opened as a museum in 1793, is one of the largest museums in the world.‎ ‎64.‎ In the late 1980s about 4.1 million pupils annually attended about 47,000 elementary schools. In addition, about 5.4 million students attended some 11,200 secondary schools. Approximately 1.2 million students were enrolled annually at universities and colleges in France in the late 1980s. French centers of learning have served as academic models throughout the world.‎ ‎65.‎ Paris‎ is the leading industrial center of France, with about one quarter of the nation’s manufacturing concentrated in the metropolitan area. Industries of consumers’ goods have always been drawn to Paris by the enormous market of the big population; and modern, high technology industries also have become numerous since World War Ⅱ. Chief manufactures are machinery, automobiles, chemicals and electrical equipment.‎ 第二卷 第三部分：写作（共三节，满分55分）‎ 第一节 单词拼写（共10小题，每题1分，满分10分）‎ 66. We’d better drink (煮开旳) water, or we’ll be sick.‎ 67.
