His enemies were searching for him. All around him were grassy hills without trees. He had nowhere to hide. How could he escape?Hannay walked along the country road for a long time. Then he saw a road worker, who was working alone, fixing the road. Hannay could see the road worker was not feeling well. Hannay came up to him and said, “How are you?” “My head hurts,” the road worker said. “I can’t do it. I want to go home. My daughter got married yesterday, and I drank a lot of wine with my friends. That’s the problem!” Hannay agreed that he should be home in bed. “Yes, and I would have been,” he replied. “But yesterday I received a message saying that the new surveyor was coming to check my work. If he comes and finds me away, I’ll be in trouble.” Suddenly, Hannay had a bright idea—he could act as the road worker and get away from his enemies. “You go off to bed,” Hannay said. “I’ll do your job until the new surveyor comes.” The road worker was pleased with his idea. He gave Hannay his hat and his old coat. Then he went home to sleep and perhaps to drink a bit more. Hannay put on the road worker’s hat and coat and began to fix the road.About an hour later, he heard a voice. “Are you the road worker?” it asked. It was the new surveyor. He was a young man with a clean face. He sat in a small car. Hannay said yes. The surveyor told him about some work he wanted him to do before he came by again and drove off. Hannay continued with his work. Then a village boy came by. “What has happened to the road worker?” he asked. “He stayed at home today,” Hannay replied. “He’s sick.”At about midday, a large car came down the hill and stopped near Hannay. Three men got out of the car. Hannay’s heart beat fast. He knew his enemies were coming.4．What is this passage probably taken from?A．A history book.B．A travel book.C．A novel.D．A science book. 5．Who did not come while Hannay was working on the road?A．The new surveyor.B．The road worker’s daughter.C．Hannay’s enemies.D．A village boy.6．What can we infer (推断) from the story?A．Hannay helped the road worker because he was warm-hearted.B．The grassy hills were a perfect hiding place for Hannay.C．The new surveyor had a lot of working experience.D．The village boy knew the road worker.7．What is the correct order of the story?①Hannay met a sick road worker and offered to take over from him.①Hannay was worried because his enemies were looking for him.①A car stopped near Hannay and three men got out.①Hannay acted as the road worker when the new surveyor came by.① The village boy wondered what had happened to the road worker.A．①→①→①→①→①B．①→①→①→①→①C．①→①→①→①→①D．①→①→①→①→①The traditional Chinese lunar calendar divides the year into 24 solar terms. They mark the changing seasons and agricultural cycle. Among the 24 solar terms, Xiaoman, the eighth solar term, falls around May 20th each year.The name “Xiaoman” means “little full” in Chinese, showing the fact that the foods in the field are beginning to be full, but they are not yet ripe. It’s a time when farmers can watch their fields turn golden under the warm spring sun. They hope to have a good harvest soon in autumn.During Xiaoman, the weather gradually changes from spring to summer. The days become longer and hotter, and the rainfall increases, providing the necessary water for food growth. This period is important for farmers, as it can influence the quality of their harvest.A special custom related with Xiaoman is silkworm raising. Silkworm raising is an important way to make a living for people who live in the south of the Yangtze River, especially in Jiangsu and Zhejiang provinces. The ancient Chinese believed that Xiaoman was the birthday of the god of the silkworm. Silkworms need to be taken good care of at this time of the year with the fresh mulberry (桑葚) leaves. It’s also regarded as the best time to cook cocoons (茧) and produce silk. Famous Chinese poets such as Li Bai and Du Fu from the Tang Dynasty, and Su Shi from theSong Dynasty all wrote poems that described the silkworm raising activities at that time.Today, it’s popular for Chinese children to raise white silkworms in a paper box, covered with fresh green mulberry leaves. For them, raising silkworms is not a way to make a living, but to see the magic of nature. It’s exciting to carefully watch the silkworms grow bigger and bigger, and finally become white cocoons.8．What does the underlined word “ripe “in Paragraph 2 mean?A．Completely broken.B．Slowly changed.C．Fully grown.D．Nearly endangered.9．Why does the writer mention the poems in Paragraph 4?A．To tell us there are a lot of famous poems in Tang Dynasty and Song Dynasty.B．To stress the silkworms need to be carefully taken care of.C．To show silkworm raising is popular during Xiaoman in history.D．To explain the poets are good at writing different kinds of poems.10．What does “them” in the last paragraph refer to?A．leaves B．Chinese children C．silkworms D．solar terms 11．What can we learn from the passage?A．The temperature drops day by day during Xiaoman.B．Xiaoman is the 4th solar term in a year.C．Farmers can have a good harvest during Xiaoman.D．Xiaoman is a good time for the foods in the field to grow.Does life sometimes seem to be full of impossible problems? How many times, for example, do you find yourself saying things like “I really don’t understand this math problem” or “I can’t get into the school team”? Well, maybe it’s time to introduce yourself to the power of “yet”. By adding this simple word, you can change everything. “I really don’t understand this math problem yet.” “I can’t get into the school team yet.” Suddenly, the impossible becomes possible. You can imagine those things happening.I read about a school that has changed the way it marks its students’ exams. The school found out that the old pass/fail system wasn’t helping with students motivation (积极性). If you passed, then great, but those students who didn’t pass often felt like failures. So now students whodon’t pass the exams will not see a big red “F” on their papers; they see a “Not yet” instead. That way the students feel that they are on a journey. They haven’t reached the end, but they know that they are going the right way.This kind of thinking is part of what experts call “having a growth mindset”. People with a growth mindset don’t concentrate on failure. They aren’t worried by not getting things right the first time and are happy to keep trying until they do. They enjoy the challenge and believe they can change. In contrast, people who just focus on the failure have what the experts call “a fixed mindset”. These people are always worried about failure and are happy to give up when things don’t go right. They don’t think that they are able to change. Clearly, it is better to have a growth mindset than a fixed mindset.But don’t worry if you think that you have a fixed mindset. You can train yourself to develop a growth mindset. Remember that it all starts with questioning the things you believe about yourself. Stop believing that you can’t or haven’t and realize that you just can’t or haven’t yet. Once you start doing this, you’ll wonder why you didn’t do it before. It’s one small but very powerful word.12．When should we use the simple word “yet”?A．When we have trouble.B．When we win an important game.C．When we meet our old friends.D．When we study in a foreign country. 13．The example in Paragraph 2 is to ________.A．express a feeling B．describe a problem C．show the resultD．support the topic14．According to the passage, which one of the following has “a growth mindset”?A．Jack got an “A” in the exam. He was quite happy to tell his parents.B．David failed in a competition, but he stays confident and keeps trying.C．Jenny found it hard to work out the math problem, so she gave it up.D．Emma was refused by the school team. She didn’t want to have another try.15．Which of the following can be the best title for the passage?A．The power of “yet”B．Two different mindsetsC．Nothing is impossible D．On the way to success二、任务型阅读阅读以下材料，从方框中所给的A—E五个选项中选出符合各部分信息的问句（其中一项是多余选项），将其序号填入第1—4小题，并回答第5小题。

She was 35 . She spent the first several weeks just talking to me - asking me all kinds of questions about myself, especially my feelings. And she 36 . She then began to teach me about the speech. Not just about my speech, but about everybody ,s. I 37 in my old school and was a pretty good tenor (男高音), but I learned that the new school ,s singing group was all filled up. It was such bad news, 38 I thought that was the one thing I could really do well - and I could do it 39 stuttering. Somehow Mrs. Claussen finally got me in the group. I felt like she really cared about me as a person, not just a speech student.During the next two years, my speech didn ,t get much better - except with her. When I was in college, things got 40 .

Last October 10th was Tony's birthday, so Mr. Clinton decided to drive him to New York, for the first game of the World Series. They had no ticket but hoped to buy a pair from scalpers.It was a two hours' ride. After they arrived, they walked in the street for two hours, carrying a sign(牌子) that read, " We need two tickets.〞There were many scalpers around, but the cheapest ticketwas $200. They were about to leave when suddenly a man stopped them. He took out two tickets and handed them to Mr. Clinton."How much do you want?""Just a present," said the man. "Enjoy the game."Mr. Clinton wouldn't accept, so the man explained, "I'm Jackson. Hans is my boss. He and his wife haven't missed a World Series in 18 years. But he is ill and can't watch the game this time. So he told me to give the two tickets to people who I thought would actually enjoy the game. A lot of people looked as if they might just take the tickets and sell them. Then I saw you and I followed you for a while. You seemed very disappointed. You made me think of my dad and me when I was a child. I dreamed of going to a World Series game with my father. But my dream never came true."How do you suppose this made Mr. Clinton and his son feel? Here is what Mr. Clinton said: "This is the most wonderful thing that ever happened to us. My boy and I must have turned to each other over 30 times and said, 'I can't believe this.' We still never forget Jackson and Hans."46. Why did Mr. Clinton go to see a game of the World Series?A. Because he is a basketball fanB. Because it was his son ,s birthday and he loves basketball.C. Because it was his birthdayD. Because he wanted to relax himself and his son.47.

If you cannot see the chance of doing something, just give it up.D. Never lose your heart when you are down, as there ,s always a hope.BHave you ever thought about what kind of job you would like to have when you grow up? Many people think that we can have only one job in our lifetime. We all know that this is not true, but quite a few people actually think this way. For example, when people choose a major in college, they think that the decisions they make now will decide their jobs for the rest of their lives. However, there are manyexamples where people became successful after changing their careers (职业) later in life.J. K. Rowling, writer of the famous novel Harry Potter, was actually a school teacher before she began writing books. In fact, she was out of work before the first Harry Potter book came out.Former US President Ronald Reagan began as an actor when he was a young man. He later decided that he wanted to do political work. This kind of passion (激情) finally led him to become President of the United States.The famous 19th century artist Vincent Van Gogh was not a painter from the beginning. He once worked as an art salesman and later became a preacher. It was only 10 years before he died that he decided to become an artist.Careers are always open to change. The important thing is to find what you are really good at or what your really want to do. Once you find that passion, it ,s all a matter of how hard you try.51. _________ was s teacher before he (she) became famous.A, Vincent Van Gogh B Ronald ReaganC. J. K. RowlingD. Harry Potter52. For some people, the majors they choose in college will decide _________A. how rich they will beB. how successful they will beC. what their jobs will beD. who they will be53.

Not many people can be successful after they change their jobsB. J. K. Rowling worked in a school as a teacher before her first book came out.C. To choose the right career, you just need to try hard enough.D. Vincent Van Gogh had been an artist only for ten years before he died.55. According to the passage, the most important thing to think of when choosing career is _________.A. what major you choose in collegeB. how much money you can makeC. changing jobs as often as possibleD. finding what you really want to do第二节：阅读下面文章,然后从文后所给的A -F六个选项中选择正确的小标题(有一个多余) ,将其序号填入56 -60题."Hi there, how are you doing?〞"Great, thanks, how are you?〞"Just fine, thank you - uh, and you?〞Ugh. Pause (停顿). Uncomfortable silence. Downward look. Now what? Here are some pieces of advice on how to keep small talk going.56When talking to someone one -on -one, you have one minute to find out everything about them. You have the rest of your life to tell them about you. So let the other person talk.57The most basic thing to do is keep things simple. "What are your plans for the weekend?〞"How did you spend the holiday?〞Stay away from difficult topics.58If you don ,t know the person well or haven ,t seen them for a while, don ,t suppose they are still working for a specific company or they are still married, and so on. Ask "What ,s been going on with the work?〞instead of "How ,s the job at the newspaper?〞59About 99 percent of the time, being right doesn ,t really matter. If someone says a car is a nice kind of blue, but it doesn ,t look blue, there ,s completely no reason to be right. Be agreeable.60Don ,t just say. "I had a great day.〞Tell them a story. People love stories, be it something that happened at work or with the family. It ,s more interesting than facts.A. Tell a storyB. Avoid disagreementC. Be unclearD. Keep it simpleE. Be a good listenerF. Wait for othersVII. 词语填空(共10小题,计10分)用方框中所给单词的适当形式填空,使短文通顺正确、连贯(每个单词限用一次) . careful, share, rule, happy, clean, advice, than, from, who, talkAt some time in your life ,you might have a roommate. 61 a flat can be fun.

(停20秒)Energy from the sun warms the ground, and some of his heat is back into the air. As the warm air rises, it cools down. Places that are high above sea -level, such as mountains, have cooler weather than places lower down.Energy from the sun warms the oceans, rivers and lakes, making some of the water rise into the sky. It rises to form clouds, and then falls back to the earth as rain, or snow. So places near the coast have wetter weather than islands.You can know by the following experiments. First, please get ready a ball and a light bulb. The ball can be regarded as the earth and the light bulb is just like the sun. Hold the ball in one hand. Shine the light onto the middle of the ball. The circle of bright light at the center of the ball is similar to the sun ,s light shining at the equator.Now find out how the light is shining at the bottom of the ball.
