They can be found almost all over the world, and there are more than 2500 kinds of them.No one likes the mosquito. But the mosquito may decide that she loves you. She？ Yes，she. It‘s true that male mosquito doesn’t bite（咬）and only the femalemosquito bites because she needs blood to lay eggs. She is always looking for things or people she wants to bite. If she likes what she finds, she bites. But if she doesn‘t like your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites you, just remember you are chosen. You’re different from the others！If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly and quietly that you may not feel anything different. After she bites, you will have an itch（痒） on your body because she puts something from her mouth together with your blood. By the time the itching begins, and she has flown away.And then what happens？Well，after her delicious dinner，the mosquito feels tired. She just wants to find a place to have a good rest. There, on a leaf or a wall, she begins to lay eggs，hundreds of eggs.5. “Mosquito” means _______ in Chinese.A. 苍蝇B. 蜻蜓C. 跳蚤D. 蚊子6.

The mosquito bites you _________.A. when you‘re asleepB. because you have choose itC. too quickly to let you knowD. but doesn‘t like youCSatellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash into each other．9.Which of the following is NOT done by satellites according to the passage? A．Sending information for weather forecast B．Taking photographs of the Earth C．Sending TV pictures D．Providing food for airplane pilots 10.What’s the speed the earth rotates at?A．35,880 kilometers per hour． B．335,880 kilometers per hour C．11,000 kilometers per hour． D．110,000 kilometers per hour11.Which is true of satellites?A．A satellite usually works for about 10-12 years．B．Every time a satellite gets broken，it is brought back to the Earth to be repaired．C．A broken satellite is never left in spaceD．They often crash into each other．DOne night Mr. Lee was driving his wife home from work. She was a staff nurse in a hospital. It was almost midnight and she was quite tired out. She soon fell asleep. Mr Lee looked at her and smiled.Mr. Lee was a cautious and experienced driver. He knew it was safer to drive slowly on a dark night. After some time he noticed a car following him. It was traveling very fast. Suddenly it overtook his car.The driver of the car was in a hurry. He did not see the approaching lorry(货车). To avoid hitting it, he swerved his car. It skidded off（打滑） the road and hit a big tree. The driver and his passenger were injured. They were badly cut by glass splinter（碎片） from the broken windscreen.Mr. Lee quickly stopped his car by the side of the road. His wife got out of the car to help the injured men. The lorry driver also stopped to lend a helping hand. Mr. Lee immediately drove off to telephone the police.About twenty- five minutes later, a police car and an ambulance arrived. The injured men were carried into the ambulance and taken to hospital.The policemen took down details of the accident. Mr. Lee and the lorry driver told them all that they could remember. The policemen thanked them for their help. Mr. and Mrs. Lee then got into their car and continued their journey home.12.

Most of us want Wi-Fi everywhere as if we can't live without it. 2 We still have to spend some money accessing(连接)the Internet at most time. 3A rich, powerful organization in the USA called the Media Development Investment Fund (MDIF) has decided to change the age of online computing (计算) completely by giving free Wi-Fi to every person on Earth. 4 This is because they have made a survey and found that only 60% of the world's population have been able to get information on the Internet. 5We can expect to use free Wi-Fi everywhere in the near future.A.However，there is another more important one thing.B.Have you ever searched for Wi-Fi when you are at restaurants or hotels ?C.Some of them started worrying about it.D.Here comes a piece of good news.E.And this is also because many countries are unable to offer people the necessary infrastructure(基础设施)to access the web.F.But we can only use free Wi-Fi in some public places.G.They will send up hundreds of satellites into low Earth orbit(轨道)in 2015. 完型填空Two teenagers who are lost at sea off the United States for six days were saved yesterday.Driscoll, 15, and his best friend, 18-year-old Josh Long, were found on Saturday about 11 km 21 Cape Fear in North Carolina.

They realized they were 27 almost immediately and tried to swim back to 28 , 29 the boat along with them.Within 30 , they were far out at sea.“We 31 our fishing equipment on the second day,” Driscoll said. “So we couldn’t catch any fish.”The boys’ hopes faded 32 each day. They stood on their boat 33 they saw another boat, 34 . One night they were woken up by 35 coming into the boat.A large ship was very close to them.“36 was like some huge building in the water,” Driscoll said.At one point, the boys thought they had gone across the Atlantic Ocean and were close to Africa. 37 , they were 179km north of their starting point.

One expert points out that the percentage(比率) of native English speakers is declining(降低) globally while the languages of other rapidly growing regions are being spoken by increasing numbers of people. But English will continue to remain widespread and important.However, British language scholar David Graddol says English will probably drop in dominance(主导) by the middle of this century to rank, after Chinese, about equally with Arabic, Hindi, and Urdu. “The number of people speaking English as a first language continues to rise, butit isn’t rising nearly as fast as the numbers of ma ny other languages around the world, simply because the main population group has been largely in the less developed countries where languages other than English have been spoken,” he says.In a recent article in the journal Science, Mr. Graddol noted that three languages that are not near the top of the list of the most widely spoken now might be there soon. These are Bengali, Tamil, and Malay, spoken in south and Southeast Asia.David Crystal, the author of the Cambridge Encyclopedia of the English Language, says about 1.5 billion of the world’s six billion people speak it as a second tongue compared to the 400 million native speakers. But another expert on the English language says Mr. Graddol underestimates (低估) the future of its dominance. “Nobody quite knows what’s going to happen because no language has been in this position before. But all the evidence (证据) suggests that the English language snowball is rolling down a hill and is getting faster,” he said.36. In David Graddol’s opinion, En glish will _______.A. remain widespread and importantB. be more important than any other languageC. lose its dominant positionD. die away in the near future37. The underlined sentence in the last paragraph implies that ______.A. snowballs will roll down faster than language ballsB. the English language snowball is rolling down faster than any time in the pastC. English language will soon drop in dominanceD. more and more language users will choose English38. How many experts does the passage mention who express their ideas about the future of English?A. 2.B. 3.C. 4.D. 5.39. According to David Graddol, which of the following will possibly be one of the languages that will be most widely spoken?A. Malay.B. Arabic.C. Urdu.D. German.40. What should be the best title for the passage?A. English Remaining the Dominant PositionB. The Future of English? Who Knows?C. Opinions from Different ExpertsD. The English Language Snowball Rolling DownBLanguage learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners .Most child ren will “obey” spoken instructions some time before they can speak, though the word “obey” is hardly accurate as a description of the eager and delighted cooperation usually shown by the child .Before they can speak, many children will also ask questions by gesture and by making questioning noises.Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these can’t be said to show the baby’s intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation（模仿）leads on to deliberate（有意的）imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.It is a problem we need to get out teeth into. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world .Thus the use at seven months of “mama” as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself, I doubt, however whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.41. Before children start speaking________.A. they need equal amount of listeningB. they need different amounts of listeningC. they are all eager to cooperate with the adults by obeying spoken instructionsD. they can’t understand and obey the adult’s oral instructions42. Children who start speaking late ________.A. may have problems with their listeningB. probably do not hear enough language spoken around themC. usually pay close attention to what they hearD. often take a long time in learning to listen properly43. A baby’s first noises are ________.A. an expression of his moods and feelingsB. an early form of languageC. a sign that he means to tell you somethingD. an imitation of the speech of adults44. Th e problem of deciding at what point a baby’s imitations can be considered asspeech________.A. is important because words have different meanings for different peopleB .is not especially important because the changeover takes place graduallyC. is one that should be properly understood because the meaning of words changes with ageD. is one that should be completely ignored（忽略）because children’s use of words is often meaningless45. The speaker implies________.A. parents can never hope to teach their children new soundsB. children no longer imitate people after they begin to speakC. children who are good at imitating learn new words more quicklyD. even after they have learnt to speak, children still enjoy imitating卷II一. 单词拼写(10分)1.
