One important form of soil conservation is the use of windbreaks. Windbreaks are barriers formed by trees and other plants with many leaves. Farmers plant them in lines around their fields.Windbreaks stop the wind from blowing soil away. They also keep the wind from destroying or damaging crops. They are very important for growing grains, such as wheat. There have been studies done on windbreaks in parts of West Africa, for example. These found that grain harvests can be twenty percent higher in fields protected by windbreaks compared to fields without such protection.However, windbreaks seem to work best when they allow a little wind to pass through. If the wall of trees and plants stops wind completely, then violent air motions will take place close to the ground. These motions will lift soil into the air where it will be blown away.For this reason, a windbreak is best if it has only sixty to eighty percent of the trees and plants needed to make a solid line. An easy rule to remember is that windbreaks can protect areas up to ten times the height of the tallest trees in the windbreak.There should be at least two lines in each windbreak. One line should be large trees. The second line, right next to it, can be shorter trees and other plants with leaves. Locally grown trees and plants are best for windbreaks.41．What is the best title for the passage?A. Building a windbreak to protect soilB. Building a windbreak to protect cropsC. Using a windbreak to improve grainsD. Using a windbreak to improve plants42. In the third paragraph the author tells us windbreaksA. Do not work at allB. Do not stop wind fullyC. Will not take placeD. Will not allow wind to pass through43. Windbreaks consist of ___.A. treesB. plantsC. soil and windD. trees and plants44. According to the passage, which of the following statement is wrong?A. Windbreaks are barriersB. Windbreaks can be used to make fencesC. In general, there are two lines in all in every windbreakD. Windbreaks can protect areasBArriving in New YorkThere are three airports in New York. When you arrive at one of them, you can take a bus or taxi to any place in New York.Public transportIn New York there’s a good bus and subway service. If you are planning to use the subway a lot, you should buy a subway ticket for ten journeys because it’s cheaper. But you don’t have to use public transport—there are lots of places you can go to on foot, like the Empire State Building, 5th Avenue and Central Park. In New York taking the taxi is a part of the city experience, so you should take the taxi at least once during your visit!HotelsThere are lots of good hotels in New York. The best is the Plaza on 5th Avenue. But you don’t have to pay a lot for stay in the city; there are lots of smaller hotels and the YMCA near Central Park is great for young people.Eating outThere are many kinds of food in New York and you shouldn’t eat at McDonald’s every day. There are good restaurants in Little Italy and Chinatown.ShoppingShopping in New York is fun. There are big shops on 5th Avenue. They are open seven days a week. But be careful when you look at the prices. You have to pay a special 8% tax on everything you buy in New York.Places to seeFinally, there are a lot of places to see in New York—Times Square, the Statue of Liberty. And you shouldn’t go ho me without climbing the Statue of Liberty to enjoy the scenery of the city.45. How much do you have to pay if you buy a book of $10 in New York?A. $ 10.8B. $10.08.C. $18.D. $ 10.46. When you visit New York, you should _______.A. eat at McDona ld’s every dayB. take a taxi whenever you go outC. stay at the best hotelD. climb the Statue of Liberty47. From the passage, we can learn that________.A. you should take a bus to travel because it’s much cheaper.B. New York is not a good place for shopping, for things are expensive.C. people can visit many places of interest in New York on foot.D. you are not allowed to go home without climbing the Statue of Liberty.CFederal regulators Wednesday approved a plan to create a nationwide emergency alert system using text messages delivered to cell phones.Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates more than 48 billion text messages are sent each month.The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation's emergency alert system. The act tasked the Federal Communications Commission (FCC) by coming up with new ways to alert the public about emergencies.“The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public hasthe information they need to take action to protect themselves and their families before, and during, disasters and other emergencies,” FCC Chairman Kevin Martin said following approval of the plan.Participation in the alert system by carriers –telecommunications companies is voluntary, but it has received solid support from the wireless industry.The program would be optional for cell phone users. They also may not be charged for receiving alerts.There would be three different types of messages, according to the rules.The first would be a national alert from the president, likely involving a terrorist attack or a nationwide disease. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child kidnapping emergencies.The service could be in place by 2010.48. What is the purpose of the approved plan?A. To warn people of emergencies through messages.B. To popularize the use of cell phones.C. To estimate the monthly number of messages.D. To promote the wireless industry.49. The improvement to the present system is in the charge of ____.A. CTIAB. the Warning Alert and Response Network ActC. FCCD. federal regulators50. An alert message will NOT be sent if _____.A. a child gets robbed in the streetB. a university shooting happensC. a natural disaster happensD. a terrorist attack occurs51. Which of the following would be the best title for the text?A. Cell Phone Alerts Protecting StudentsB. Cell Phone Alerts by Wireless IndustryC. Cell Phone Alerts of National DisastersD. Cell Phone Alerts Coming SoonDDuring London’s 8-minute show at the Closing Ceremony of the Beijing Olympic Games, fans were thrilled by the performance of a young British singer with the famous rock guitarist Jimmy Page. Who was that curly-haired singer?She’s Leona Lewis，a 23-year-old pop and R&B singer-songwriter and the winner of the 2006 UK television talent show The X Factor. Her UK debut single(首张单曲唱片), A Moment Like This, broke a world record after it was downloaded over 50, 000 times within 30 minutes．Leona was a working-class girl from London，with a normal family, a steady boyfriend and a job as a receptionist(接待员)when she tried out for the show. Her father was a part-time DJ, and there was always music in the house. From an early age, she was always jumping on the coffee table, singing along to Michael Jackson and Whitney Houston. When she went to stage school, everyone else in her class was richer than she was. But she didn’t feel left out. She just focused on her singing. Lewis wrote her first song at the age of twelve, and won a number of talent competitions. After leaving school, Lewis took a number of jobs to pay to get into a recording studio, including waitress and several receptionist jobs.Her efforts finally paid off. Her first album, Spirit, released in several countries in 2008, went to No．1 in the US，New Zealand, Australia, Austria, Germany, South Africa and Switzerland. The second album is planned for release in 2009, and it has been reported that she is planning a ￡15 million (190 million Yuan)world tour in 2010.Leona has succeeded before everyone’s eyes, turning from a pretty 21-year-old girl in 2006 into a star singer in 2008．But to some degree, she still seems to be the girl next door. Although she landed her feet on the ground, she hash’t chan ged. She is very polite and respectful, but she knows what she wants.52.

At some point in every speech, every speaker says something that is not understood exactly as he has planned. Fortunately, the moments are usually not obvious to the listeners. Why? Because the listeners do not know what the speaker plans to say. They hear only what the speaker does say. If you lose your place for a moment, wrongly change the order of a couple of sentences, or forget to pause at a certain point, no one will be any the wiser. When such momen ts occur, don’t worry about them, Just continue as if nothing happened.Even if you do make an obvious mistake during a speech, that don’t really matter .If you have ever listen to Martin Luther King’s famous speech –“ I have a dream”, you may notice tha t he stumbles（结巴）his words twice during the speech. Most likely, however, you don’t remember. Why? Because you were fixing your attention on his message rather than on his way of speech-making. People care a lot about making mistakes in a speech because they regard speech-making as a kind of performance rather than as an act of communication. They feel the listeners are like judges in an ice-skating competition. But, in fact, the listeners are not looking for a perfect performer. They are looking for a well-thought-out speech that express the speaker’s ideas clearly and directly. Sometimes a mistake or two can actually increase a speakers’ attractiveness by making him more human.As you work on your speech, don’t worry about being imperfect. Once you free your mind of this, you will find it much easier to give your speech freely.56. The underlined part in the first paragraph means that no one will ___________.A. be smarter than youB. notice your mistakesC. do better than youD. know what you are talking about57. You don’t remember obvious mistakes in a speech because ___________.A. your attention is on the contentB. you don’t fully understand the speechC. you know what the speaker plans to sayD. you find the way of speech-making more important58. It can be inferred from the passage that ___________.A. giving a speech is like giving a performanceB. one to two mistakes in a speech may not be badC. the listeners should pay more attention to how a speech is madeD. the more mistakes a speaker makes, the more attractive he will be59. What would be the best title of the passage?A. How to Be a Perfect SpeakerB. How to Make a Perfect SpeechC. Don’t Expect a Perfect SpeechD. Don’t Expect Mistakes in a S peech60. Which of the following statements is true?A. If you are careful enough, you can make a perfect speech.B. Speech-making is a kind of performance.C. Listeners are not judges and they pay more attention to the message.D. Martin Luther King is not a good speaker.第二卷(共40分)第三部分：写作（共三节，满分40分）第一节：单词拼写（共10小题；每小题1分，满分10分）根据下列句子及所给单词的首字母，在答题纸上按题号写出各单词正确的完全形式（每空限写一词）。
