It seems there is a scientific reason for this.Researchers are now studying the relationship between music and remembering a foreign language. They find that remembering words in a song is the best way to remember even the most difficult language.“Singing could be a new way of learning a foreign langu age. The brain likes to remember things when they are used in a catchy and meaningful way”, said Dr, Karen Ludke. The findings may help those who have difficulties learning foreign languages. On his blog, Dr. Ludke writes, “A listen-and-repeat singing method can support foreign language learning, and opens the door for future research in this area.”Many language teachers know the value of using music and singing. Hua Zhuying, a teacher at a Chinese language school in Washington, D.C. depends heavily on songs in teaching Chinese. She says, “I use music all the time to teach children Chinese. For little kids usually we use the music. Not only does it work, but it is fun for kids.”“Sometimes, I think if I were taught English that way, maybe I could speak mu ch better English than now,” Hua Zhuying adds.Our brain likes music, especially for remembering. So, if you’re still struggling in learning a language, why not try singing it out ?16. According to the passage, the best way to remember a foreign language is to .A. listen to the teacher carefullyB. copy the words many times.C. remember words in a songD. read and write more17.The underlined word “catchy” probably means “____”A.infamousB. boringC. impressiveD.emotional18.Dr. Ludke believes that foreign language learning can be supported by .A. writing songs with the languageB. listening to all kinds of famous musicC. using the listen-and-repeat singing methodD. reading the lyrics again and again19.From the passage, we know that Hua Zhuying .A. is interested in writing English songsB. teaches Chinese in an American schoolC. teaches children English by using musicD. is a researcher in a language school20.The passage mainly tells us that .A. many researchers realize the importance of language studyingB. many language teachers know the value of famous musicC. your brain remembers a language better if you sing it.D. you will never learn a language well unless you can singPassage 2Mass media are tools of communication. Mass media can be divided into two groups: print media and electronic media. By print media, we mean books, newspapers and magazines. Electronic media include television, computer, radio and movie. Mass media allow us to record and pass information rapidly to a large, scattered audience.They extend our ability to talk to each other by helping us overcome barriers caused by time and space. There are various ways in which mass media make daily life easier for us. Firstly, they inform and help us keep a watch on our world. They gather and pass on information we would be unlikely or unable to obtain on their own.Secondly, mass media help us to arrange our time and life. What we talk about and what wethink about are greatly influenced by the media. When people get together, they tend to talk about certain happenings in newspapers or on TV. Because we are exposed to different points of view through different kinds of media every day, we are able to evaluate all sides of a certain issue.Thirdly, the media are used to persuade people. A good example is advertisements through the media. Newspapers, magazines and TV are filled with all kinds of colorful, persuasive advertisements. Though many advertisements may not say openly that they want you to buy a certain product, they describe their products in such a way that you may want to buy them.Fourthly, the media also entertain. All of the media make efforts to try to entertain their audience. For instance, even though the newspaper is a prime medium of information, it also contains entertainment features. Television, motion pictures, fiction books and some radio stations and magazines are devoted mainly to entertainment. It is estimated that in the future, the entertainment function of mass media will become even more important than it is now.21. What makes it possible for people living in different places to communicate with each other?A. Printed mediaB. Mass mediaC. Electronic mediaD. Computers22. Which of the following functions of mass media is Not mentioned?A. To make people well informed about the worldB. To amuse and entertain peopleC. To help people arrange their time and lifeD. To give people a sense of honor23. Certain matters in newspapers or on TV tend to be talked about when people get together because ____.A. people are curious about themB. people are influenced by those mass mediaC. it is fashionable for people to do soD. it is easy for people to communicate in this way24. How does advertisement make people purchase certain goods according to the passage?A. By giving an attractive account of the goods.B. By asking people to buy them.C. By forcing people to buy them.D. By giving people something extra.25. Which of the following media is mainly devoted to information according to the passage?A. TVB. MagazinesC. Motion PicturesD. NewspapersPassage 3When international aid is given, steps must be taken to ensure (确保)that the aid reaches the people for whom it is intended. The way to achieve this may not be simple. It is very difficult for a nation to give help directly to people in another nation. The United Nations Organization (UNO) could undertake to direct the distribution of aid. Here however rises the problem of costs. Also tied with this is time. Perhaps the UNO could set up a body of devoted men and women in every country who can speedily distribute aid to victims of floods and earthquakes.More than the help that one nation can give to another during a disaster; it would be more effective to give other forms of help during normal times. A common proverb says, “Give me afish and I eat for day, teach me to fish and I eat for a lifetime.” If we follow this wise saying, it would be right to teach people from less developed nations to take care of themselves. For example, a country could share its technology with another. This could be in simple areas like agriculture or in more complex areas like medical and health care or even in building satellites. Even small country is able to help less developed nations. Sometimes what is take for granted, like the setting up of a water purification plant or the administration of a school, could be useful for countries which are looking about to solve common problems. It does not cost much to share such simple things. Exchange students could be attached for a number of months or years and learn the required craft while on the site. They can then take their knowledge back to their homelands and if necessary come back from time to time to clear doubts or to update themselves. Such aid will be truly helpful and there is no chance of it being temporary or of it falling into the wrong hands.Many countries run extensive courses in all sorts of skills. It will not cost much to include deserving foreigners in these courses. Besides giving effective help to the countries concerned, there is also the build-up of friendships to consider. Giving direct help by giving materials may be effective in the short run and must continue to be given in the event of emergencies. However, in the long run what is really effective would be the sharing of knowledge.26. According to the author, how could international aid reach the victims in time?A. By solving the cost problemsB. By solving the transportation problemsC. By relying on the direct distribution of the UNO.D. By setting up a body of devoted people in every country.27. What does the author try to express in the underlined sentence?A. Providing food is vital. Learning to fish is helpfulC. Teaching skills is essentialD. Looking after others is important.28. The second paragraph is developed mainly ____.A.by contrastB.by processC.by comparisonD.by example29. Which aid is likely to fall into the wrong hands?A. A medical team.B. An exchange program.C. Financial support.D. A water plant.30. What can we infer about international aid from the passage?A. It is facing difficultiesB. It is unnecessary during normal timesC. It should be given in the form of materialsD. It has gained support from developed countriesPassage 4Human needs seem endless. When a hungry man gets a meal, he begins to think about an overcoat; when a manager gets a new sports car, a big house and pleasure boats dance into view.The many needs of mankind might be made up of several levels. When there is moneyenough to satisfy one level of needs, another level appears.The first and most basic level of needs involves food. Once this level is satisfied, the second level of needs, clothing and some sort of shelter, appears. By the end of World WarⅡ, these needs were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses.By 1957 or 1958 this third level of needs was fairly well satisfied. Then, in the late 1950s, a fourth level of needs appeared: the “life-enriching” level. While the other levels involve physical satisfaction, that is, the feed in comfort, safety, and transportation, this level stresses mental needs for recognition, achievement, and happiness. It includes a variety of goods and services, many of which could be called “luxury” items. Among them are vacation trips, the best medical and dental care, and recreation. Also included here are fancy goods and the latest fashions.On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of needs as their income increases, or will they continue to demand luxuries and personal services on the fourth level?A fifth level would probably involve needs that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth and our minds, we now may seek to ensure the health, safety, and leisure to enjoy more fully the good things on the first four levels.31. According to the passage, man will begin to think about such needs as housing and clothing only when _____.A. he has saved up enough moneyB. he has grown dissatisfied with his simple shelterC. he has satisfied his hungerD. he has learned to build houses32. It can be inferred from the passage that by the end of World War Ⅱ, most Americans _____.A. were very richB. lived in povertyC. had the good things on the first three levelsD. did not own automobiles33. Which of the following is NOT related to "physical satisfaction"?A. A successful career.B. A comfortable home.C. A good meal.D. A family car.34. What is the main concern of man on the fourth level?A. The more goods, the better.B. The more mental satisfaction, the better.C. The more "luxury" items, the better.D. The more earnings, the better.35. The author tends to think that the fifth level .A．would be little better than the fourth levelB．may be a lot more desirable than the first fourC．may ask consumers to spend less on taxesD．would be attainable before the government takes actions三、完形填空（共15 分，每小题 1 分）Eco-tourism involves people traveling to beautiful but environmental sensitive places. Such trips are 36 carried out with an experienced guide. Over recent years, this type of travel has been steadily gaining 37 as more people search for new travel experiences.Eco-tourism has many benefits. First, all the money spent by the tourists is used to protect the important environmental spots they visit. Second, it helps visitors to better understand the environment, thereby 38 their knowledge of the world. Furthermore, this style of travel is also more 39 of the local culture.Compared to 40 tourists, eco-tourists use energy more efficiently, save water and produce less rubbish by finding ways to 41 it. These behaviors have a 42 and lasting effect on the local environment.Two things are needed to make eco-tourism a/an 43 . First, it should be done in small groups. And second, because it requires considerable effort, both eco-tourists and locals must be 44 in their commitment to improving the environment.Green travel provides local people with jobs in parks, 45 and shops. One great achievement of eco-tourism has been the 46 of illegal hunting. Former hunters can now work as guides to help keep the animals 47 in their natural surroundings. Green travel also 48 local people's quality of life, especially children's. Peru is one country using eco-tourism to promote respect for the 49 . It's now able to take better care of its rainforests because of a focus on more sustainable(不破坏生态环境的，可持续的)travel. 50 this, local people's living-standards have improved. Many others are now following Peru's example and using eco -tourism to preserve their environment for the future generations.36. A. finally B. usually C. suddenly D. roughly37. A. pleasure B. satisfaction C. popularity D. freedom38. A. approving B. confirming C. enriching D. supporting39. A. respectful B. aware C. uncertain D. independent40.
