We recycle our newspapers and bottles, we take public transport to get to work, we try to buy locally produced fruit and vegetables，and we want to take these attitudes on holiday with us. This is why alternative forms of tourism are becoming popular in the world. There are a lot of names for these new forms of tourism: responsible tourism, nature tourism, adventure tourism, educational tourism and more. Although everyone may have a different definition, most people agree that these new forms of tourism should do the following: first, they should conserve the wildlife and culture of the area; second, they should benefit the local people; third, they should make a profit without destroying natural resources; and finally they should provide an experience that tourists want to pay for. 2012专四听力参考答案

2009年4月考试真题(A卷) Part I Reading Comprehension （30%） Directions：There are three passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A，B，C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center. Passage 1 Questions 1 to 5 are based on the following passage： I hear many parents complain that their teenage children are rebelling. I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own feet. But take a good look at the present rebellion. It seems that teenagers are all taking the same way of showing that they disagree with their parents. Instead of striking out boldly on their own，most of them are holding one another's hands for reassurance （放心）。 They claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But they all end up listening to the same record. Their reason for thinking or acting in such a way is that the crowd is doing it. They have come out of their cocoon （茧）into a larger cocoon.. （76）It has become harder and harder for a teenager to stand up against the popularity wave and to go his or her own way. Industry has firmly carved out a market for teenagers. These days every teenager can learn from the advertisements what a teenager should have and be. This is a great barrier for the teenager who wants to find his or her own path. But the barrier is worth climbing over. The path is worth following. You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records. You may have some thoughts that you don't care to share at once with your classmates. Well，go to it. Find yourself. Be yourself. Popularity will come—with the people who respect you for who you are. That's the only kind of popularity that really counts. 1. The author's purpose in writing this passage is to tell______. A. readers how to be popular with people around B. teenagers how to learn to make a decision for themselves C. parents how to control and guide their children D. people how to understand and respect each other 2. According to the author，many teenagers think they are brave enough to act on their own，but in fact most of them______.

“Congratulations, Mr. Cooper. It?s a girl.” Fatherhood is going to have a different meaning and (31) a different response from every man who hears these words. Some feel (32) when they receive the news, (33) others worry, wondering whether they will be good father. (34) there are some men who like children and may have had (35) experience with them, others do not particularly (36) children and spend little time with them. Many fathers and mothers have been planning and looking forward to children for some time. (37) other couples, pregnancy was an accident that both husband and wife have (38) willingly or unwillingly. Whatever the (39) to the birth of a child, it is obvious the shift from the role of husband to (40) of a father is a difficult task. (41) , unfortunately, few attempts have been made to (42) fathers in this resocialization (43) . Although numerous books have been written about mothers, (44) recently has literature focused on the (45) of a father. It is argued that the transition to the father's role, although difficult, is not (46) as great as the transition the wife must (47) to the mother's role. The mother's role seems to require a complete (48) in daily routine. (49) , the father?s role is less demanding and (50) . 31. A. bring down B. bring forth C. bring off D. bring in 32.

A. current B. immediate C. present D. quick TEXT A We have a crisis on our hands. You mean global warning? The world economy? No, the decline of reading. People are just not doing it anymore, especially the young. Who?s responsible? Actually, it?s more like, What is responsible? The Internet, of course, and everything that comes with it —Facebook, Twitter (微博). You can write your own list. There?s been a warning about the imminent death of literate civilization for a long time. In the 20th century, first it was the movies, then radio, then television that seemed to spell doom for the written world. None did. Reading survived; in fact it not only survived, it has flourished. The world is more literate than ever before —there are more and more readers, and more and more books. The fact that we often get our reading material online today is not something we should worry over. The electronic and digital revolution of the last two decades has arguably shown the way forward for reading and for writing. Take the arrival of e-book readers as an example. Devices like Kindle make reading more convenient and are a lot more environmentally friendly than the traditional paper book.
