大学英语口语考试试题及答案

以下为爱麟霖/(Curlylin)倾情奉献,需要的朋友可以参考一下 7. Friendship (Listening and Speaking Course, Unit 3; Integrated Course, Unit 2) 1) Do you have many friends? What kind of people do you want to make friends with? Why? Yes. I’d like to make friends with loyal people. In my opinion,a friend is a person who can share his/hers happiness with you, who can lend you a shoulder when you cry,who can give you a hand when you are in trouble without asking for anything in return. In a word,a friend in need is a friend indeed, I think a loyal people can do the things which were mentioned above for his/hers true friend. So I prefer to make friends with loyal people, and I also believe I am a loyal people who you can make friends with. 2) How do you make friends? Please comment on “a friend you buy isn’t worth the price”. First,I’d like to talk to him to find out whether we have the same interest with each other. If the answer is YES,then we have the foundation to develop a friendship. The next days, all we need to do is to treat each other by heart and soul. 3) How valuable is friendship in a person’s life? How can we keep friendship alive? As for me, I regard friendship as a very important part in my life.Just imagine a life,there’s no one to be your friend. What life could be if you had no friend to talk to , no friend to comfore you and cheer you up when you were having a hard time,no friend to lend you a hand when you needed help …… Life without friends is unthinkable ... We have to do hard work to build up and sustain our friendship. First, let your friends know that you really care about them.It’s important to give some cues to your friends. Be sure your friend knows that she is cared about.Second,try to be with your friends when they are in trouble when they need you. Keeping friendship alive is not only to say some sweet words,but need some real action. 4) What does friendship mean to you? What kind of friends do you think are true friends? It's a fantastic experience in whole of my life. Friendship to me is what water to fish.I can't live without a real friend. 2问见(1) 5) How can we get along well with other people? To begin with, we need to be honest with others and always say what we mean. Lies will surely make people stay far away from us in the long run. After all,honesty is the best policy. Second, we have to be humble enough. If we are proud in public, we can hardly win other's respect, not to mention "friendship" . Finally, we must not be selfish. We should learn how to show concern for others. As long as we abide[?'ba?d] by what is mentioned above, we will find it easy to get along well with others.

Calculate for a moment what could be done with even a part of those hours. Five thousand hours, I am told, are what a typical college undergraduate spends working on a bachelor's degree. In 10,000 hours you could have learned enough to become an astronomer or engineer. You could have learned several languages fluently. If it appealed to you, you could be reading Homer in the original Greek or Dostoyevsky in Russian. If it didn't, you could have walked around the world and written a book about it. The trouble with television is that it discourages concentration. Almost anything interesting and rewarding in life requires some constructive, consistently applied effort. The dullest, the least gifted of us can achieve things that seem miraculous to those who never concentrate on anything. But Television encourages us to apply no effort. It sells us instant gratification(满意). It diverts us only to divert, to make the time pass without pain. Television's variety becomes a narcotic(麻醉的), nor a stimulus. Its serial, kaleidoscopic (万花筒般的)exposures force us to follow its lead. The viewer is on a perpetual guided tour: 30 minutes at the museum, 30 at the cathedral, 30 for a drink, then back on the bus to the next attraction—except on television., typically, the spans allotted arc on the order of minutes or seconds, and the chosen delights are more often car crashes and people killing one another. In short, a lot of television usurps(篡夺;侵占) one of the most precious of all human gifts, the ability to focus your attention yourself, rather than just passively surrender it. Capturing your attention—and holding it—is the prime motive of most television programming and enhances its role as a profitable advertising vehicle. Programmers live in constant fear of losing anyone's attention—anyone's. The surest way to avoid doing so is to keep everything brief, not to strain the attention of anyone but instead to provide constant stimulation through variety, novelty, action and movement. Quite

关键词 1.Beauty Everyone admires beauty. Everyone has his own standard about beauty. Nowadays some people tend to think that they own beauty if they have a good looking. They are not satisfied with their appearance. They spend much money taking a kind of operation. I don't think beauty can be man-made. If so, everybody can get beauty. As a result, there is no beauty at all. The appearance is given by our parents and is unique in the world. Everyone should value it. I would rather view nature as the standard of beauty. Just accept ourselves, and create the beautiful life belonging to us. Many heroes don't have beautiful surface. However, their beautiful images often come to our minds. Their beauty comes from their contributions to the society. Don't be eager to judge whether a person is beautiful or not, without a thorough understanding of him. A beautiful person is not the one with a good looking, but with a kind heart. Good looking is pleasant while spiritual (精神) beauty is more important. As an old saying goes, "Virtue is fairer than beauty. "If you have a kind heart, you own real beauty. 2.Contest ●beauty contest I think beauty contest does more harm than good. To start with ,it may lead players lack of confidence even to have a plastic 's more , It may mislead their value winner in the competition could get a lot of things, like money, fame, social awareness and so on. Then,it may cause the female pay too much attention to appearance, They may spending more time and money on fashion, cosmetics, hair styling and even cosmetic surgery . But ignore the inner beauty ,the true beauty. Finally, beauty contests are usually carried out within a period of time,we can not judge a person's beauty and ugliness, and good or bad in this limited time. So I think beauty contest does more harm than good. 3.Appearance ●In what ways can people improve their appearance? Some people just want to improve their looks in small ways. They may go on a diet to maintain a good figure, they make up to improve their appearance, put a facial mask or skin smoother on their faces during the night, have their teeth straightened, or have their nails polished. Some others have a face-lift to change their nose or chin, make their single-fold eyelids double folded, and have their skin tightened to smooth out wrinkles and crow’s feet. Some even inject botox(瘦脸针) to remove wrinkles. More drastically, some people may have liposuction to remove ,in my opinion the best way to improve appearance is trying to learn to be more elegant and to be more Knowledgeable. ●Why do some people want to improve their appearance? A love of beauty is part of human nature. People like to see beautiful scenery, flowers, and animals. It is not strange that they also want to look at good-looking humans and improve the way they look themselves. With improved features, one may find a better job, attract a more desirable spouse, and gain faster occupations attach great importance to appearance. Most actors, anchorpersons, and fashion models can be recognized by their is sometimes argued that by looking good, one tends to feel self-confident. With confidence, success is more likely to follow in any undertaking. 4.plastic surgery ●What disadvantages are there in plastic surgery?
