You'd better 16 your best to speak while you do much listening. Don't be 17 of making mistakes. But be careful not to let them stop you from improving your 18 . While you are doing this, a good 19 is to write—keep a diary, write notes or letters. Then if you can, ask some others to go through 20 you have written and tell you where it is wrong. Many mistakes in your speaking will be 21 found when you write. Through correcting mistakes, you can do better in learning English.If you are slow in speaking, don't 22 about it. One of the helpful ways is reading, either aloud or to yourself. The important thing is to choose 23 interesting to read. It mustn't be too difficult for you. When you are reading 24 this way, don't stop to 25 the new words if you can guess their meanings when they have nothing to do with the sentences. You can do that some other time.16. A. have B. send C. make D. try17. A. sure B. afraid C. proud D. tired18. A. English B. Chinese C. Japanese D. French19. A. start B. idea C. way D. manner20. A. how B. when C. why D. what21.

A. look at B. look for C. look up D. look over三、阅读理解（共9小题；共18分）AWhy are your study habits different from those of your friends? Why do you seem to learn faster in some classes while more slowly in others? One reason you may not know is that people have different types. Scientists say there are three different learning types: Visual(视觉型), Auditory(听觉型) and Kinesthetic(动觉型).Visual learners learn best by seeing. If you seem to easily remember information from pictures, graphs(图表) and videos, you are probably a visual learner. You're not good at copying down what the teacher says in class. Never mind. You can draw graphs or pictures instead, if you find that works better for you.Auditory learners learn best by hearing. If you seem to easily remember things by hearing them, then you are probably an auditory learner. You must listen carefully while the teacher is speaking because it's the easiest way for you to learn. Sometimes you may find that taking notes stops you from listening carefully. After class, you can write down what you remember or borrow your friend's notes to copy.Kinesthetic learners learn best by doing. If you seem to learn best by working with your hands, you are probably a kinesthetic learner. Taking notes by writing can make you pay close attention to information as you receive it. Of course, you can learn best by making full use of labs or other class activities.Hope you learn better by knowing what your personal learning type is.26. There are different learning types according to the passage.A. twoB. threeC. fourD. five27. Jude can remember the words of a song quickly by listening to it once or twice. She might be a/an according to the passage.A. auditory learnerB. visual learnerC. strange leanerD. usual learner28. Kinesthetic learners learn best by .A. remembering information from videosB. listening teachers in classC. drawing graphs or picturesD. doing things with their hands29. The best title of this passage may be " ".A. Study HabitsB. Ways to StudyC. Learning TypesD. Reasons to LearnBSwimming and English LearningCan you swim? Do you like swimming? Yes? Well, how can you learn to swim? I think the best way is to go into the water and learn. I'm afraid you'll never learn to swim just by reading books aboutswimming or looking at others who are swimming. It's the same with the English study. We must practice, practice and practice.Listening and speaking are very important for beginners. The children in English-speaking countries first listen to others. Then they try to imitate and speak. We can listen to English programs on the radio. You may just understand a few words. It doesn't matter. Just be relaxed, and try to catch every word.Somebody may be a good listener. But he or she dare not speak. He or she is afraid of making mistakes. You know we sometimes make mistakes when we speak Chinese. Don't be afraid. We must be brave. If you really want to learn English well, you must try to speak with everyone so long as he knows English. Whether you know him or not is not important. When there's nobody to talk with, you can talk to yourself in English. It's interesting and also a good way to practice your spoken English. Remember, the more you speak, the fewer mistakes you'll make.Reading and writing are more important for senior school students. First, we must choose the books we're interested in. A lot of reading will improve your language sense. This is the most important.Keep writing English diaries. We can also write English articles. You may even post them to English magazines. Don't be afraid of failure. Failure is the mother of success.Easier said than done. Well, let's do more practice from now on. I'm sure you'll learn English well in this way.30. You can learn to swim by .A. reading books about itB. looking at others who are swimmingC. having lessons on itD. going into the water and learning31. We can listen to English , according to the passage.A. by trainB. on the radioC. every minuteD. now and then32. What should you do with mistakes when you speak?A. Don't make mistakes.B. Study hard.C. Try not to speak English.D. Don't be afraid.33. We should learn English by .A. listening and speakingB. reading and writingC. A and BD. making mistakes34. What's more important for senior school students?A. Listening.B. Speaking.C. Reading and writing.D. Learning.四、单词拼写(单句首字母填空)（共4小题；共4分）35. The boy knows the p of the word, but he can't spell it.36. We must be p with children when they do something wrong.37. Reading a every morning is a good way to improve your English.38. I felt very n when I first made a speech in public.五、单词拼写(根据中文提示拼写单词)（共2小题；共2分）39. Brenda spent all day (准备) the meal.40. The population of this town has (增长) in recent years.六、选词填空(短文选词填空)（共10小题；共10分）How Can We Practice Our Spoken English?The first and most 41. thing is to believe yourself. You should always be full of confidence, or you will never be able to improve your spoken English. You should often encourage 42. , "Come on; don't be afraid."You should never lose heart and never 43. .Maybe you are afraid of 44. face, but you should think since we are students and we are learning, there is no need to worry about 45. . You must always be active to practice. There is no doubt that your pronunciation and intonation(语调) can't be as good as the native people because we are 46. , and we don't have chances to live in foreign countries and talk with the people there. But you must know that the main aim to study English is to make ourselves understood47. other people. You should believe that native speakers will not laugh at you.48. , they will encourage you. So if you are brave 49. , you will certainly make rapid progress in your spoken English.Don't be shy or afraid! Just have 50. try.七、阅读与表达(问答式(含翻译))（共5小题；共10分）Reading for pleasure is the easiest way to become a better reader in English. It is the most important way.Some students say that they don't want to read for pleasure. They say they want to use their time to learn the rules of the language and new words. They say that pleasure reading is too easy.Many experts say that pleasure reading is very important for English learners. Dr. Stephen Krashen, a famous expert on learning languages, says that pleasure reading helps you learn many important things about English. ③Students learn more grammar and more words when they read for pleasure. They also learn more about good writing.Dr. Krashen tells us that pleasure reading helps each student in a different way. Each student needs to learn something different. Pleasure reading makes it possible for each student to learn what he or she needs.④Reading for pleasure is not the same as studying. When you read for pleasure, you choose your own books, and you don't have to remember everything. There are no tests for your pleasure reading. Pleasure reading will help you:● learn how En glish speakers use English.● find examples of good writing in English.● learn about the cultures of English speakers.● read faster in English.● learn new words.根据短文内容，完成下列小题。

Perhaps your parents had the same problem when they were young W. hy aren ’t some parents so frd i e ly n intheir children ’s eyes?One of the most important reasons is when someone becomes a parent, he / she often worries about things. They worry about everything about you, from the time you were born (出生). They do a lot for you. Though something would make you angry, they care about you and worry about you. They worry aboutyour choice (选择) of friends, the food you eat, your study at school, how much sleep you get and so on. All these things are part of your life. They want you to grow up healthily and happily.So how can you make things easier on yourself? It ’esasier than you think. Just make sure your parents know what you’ re doing. Get them to know your friends. Phone them if you get home later than usual. Say sorry to them when you make mistakes. Talk about your ideas with them and they may talk about theirs with you.Most of all, try to think about why your parents do this or do that. They are still practising beingparents and need help you can give them. When you become a parent, they may be able to help you how toget on with your children.1 题判断正误（“T表”示正确，“F表”示错误）；27 题完成句子；3 题简略回答问题； 4 题找出并写下第二段的主题句； 5 题将文中画线句子译成汉语。

The man made hundreds of spells, but none of them worked.A young man heard about it. He went to the palace, and told the King that he could help and then gave the king two small pieces of paper. “Use the first before saying what you want people to do, and use the second after they finish doing it.” A servant was passing by (路过), carrying a large turkey in his arms. The King said to him, “Please, let me see that turkey.” The servant was surprised by the King’s kindness. He never heard him say ‘please’ before. So he gave it to the King. The King, after looking at the turkey, said, “Thank you. You may go.”And the servant left. The young man’s spells really worked! The King asked him where he got the spells. “My teacher told me that we s hould use the polite (有礼貌的) words.”The King, understanding the truth, spent the whole (整个) life to learn how to be a polite King.（）6.

Tom was sitting in front of a bright computer screen on which a motorbike was running fast."Oh, Tom. You're still playing on that computer game. You must stop now, because it's half past eleven. If you don't go to bed soon, you'll be very tired tomorrow." said Mrs. White."But I've nearly won the game." Tom said to Mrs. White. She could see the excitement on his face. She sat down beside him."You're always playing on the computer. You spend more time on this machine than on your homework."Today more and more families have computers. Parents hope computers can help their children improve their study at school. But many of their children use computers to play games and watch videos instead of studying. We often see that computer net bars are crowded with people, especially young boys. They spend a lot of money competing (竞争) with the computerized (用计算机控制的) machines. The more they lose, the more they want to win. The result is that they don't want to work or study.In some countries, even scientists hate computers.

蔚然成风：“蔚然”草木茂盛的样子。
（蔚然而深秀者琅琊也——《醉翁亭记》）成语指一件事情逐渐发展盛行，形成一种良好风气。
赫赫有名（来自《铁塔上的实验》）：赫赫，显著盛大的样子。
形容声名非常显赫。

The Eatery provides almost everything to _______. .A. treat people for a long timeB. meet (满足) the needs of different visitorsC. let people take awayD. help people learn about Loch Ness(B)Many Chinese people who have been to the United States think that Americans pay a little part of their money for food each day. Yet, in the latest 13 years, food prices have gone up 30% for most American families. Everyone agrees that the cost of feeding a family has risen sharply. But who is really responsible（有责任的）?Many people say the farmers who produce the vegetables, fruit, meat, and eggs are responsible. But farmers say that the rise in food prices is very small compared to (和…相比) the rise in their cost of living. Farmers think middlemen（中间人）have got much more money than they do. Middlemen are those people who stand between the farmers and the people who buy and eat the food. For example, truck drivers, owners of food stores and so on. Are middlemen really responsible for higher food prices?Economists（经济学家）don’t think so. They have found that the money that meat packers（包装商）and food stores get is less than 1% in all. They say that food costs more now because modern housewives have jobs outside the home. They have less time for co oking after a day’s wor k. They like to buy food which has already been prepared before it reaches the market. They want to buy many kinds of food that can be put on their dining tables easily and quickly. But of course they must be prepared to pay for the services of those who make their work easier.It seems that the answer to the question of rising prices is not an easy one. Quite a number of people share the responsibility for the sharp rise in food costs.( ) 6. Farmers speak for themselves because _____.A. the middlemen have had the biggest share of profit（利润）B. the cost of their products have risen sharply tooC. their cost of living has gone up a lot, tooD. they’ve got very little in the rise of food prices( ) 7.

Please keep warm. The temperature ________________ (drop) a little tomorrow morning.10. The old man had to continue ________________ (work) to support his family after he retired (退休).七、任务型阅读（10%）A long story about people is usually called a novel. It can be about any kind of man, woman, or child. It can be about kings, or Chicago newsboys, or housewives. The French writer, Victor Hugo, wrote his novel Les Miserables about a poor man who stole (偷) a loaf of bread. The American writer, Ernest Hemingway, wrote A Farewell to Arms about a young American with the Italian Army in World War One.A novel can tell the story of any kind of action, over any period of time. The modern Irish writer, James, Joyce, covers less than twenty-four hours in Ulysses. Yet, Joyce takes a thousand pages to tell all that happens from the time one man gets up in the morning until he goes to bed early the next morning. A German writer, Herman Hesse, uses only one hundred and fifty pages in his novel Demian to cover a boy’s life from the age of ten until he becomes a young man.A novel does not just tell the things that people do. It also tells why they do them. The Badge of Courage, bythe American novelist, Stephen Crane, tells about a young soldier who runs away the first time he is in the war. The book shows why he acted as he did. It describes his mental suffering (精神折磨) until he overcomes his fears.People buy novels because they enjoy reading about other people. The novel meets the human desire (欲望)八、完成句子（10%）1. 你清楚你的写作该向谁寻求帮助吗？Are you clear ___________________________________________________ your writing?2. 关于如何提高我的英语，你能给我一些意见吗？Can you give me ________________________________________________________?3. 她够聪明，知道该如何处理不同的问题。
