昆明2015高考英语阅读理解、完形填空四月自练（8）答案阅读理解。(2014天津模拟)i heard many parents complaining that their teenage children are rebelling(叛逆). 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 taking the same way of showing that they disagree with their parents. instead of striking out boldly on their own, most of them are clutching(紧握)at one anothers hands for reassurance(安慰). they claim they want to dress as they please. but they all wear the same clothes. then set off in new directions in music. but somehow they all end up with listening to the same record together. their reason for thinking or acting in thus-and-such a way is that many people are doing it. they have come out of their cocoon(茧)into a larger cocoon. it has become harder and harder for a teenager to stand up against the popularity wave and go his or her own way. industry has firmly carved out a teenage market. these days every teenager can learn from the advertisements what a teenager should have and be. and many of todays parents have come to award high marks for the popularity of their children. all this adds to a great barrier(障碍)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 dont care to share with your classmates at once, well, go to it. find yourself. popularity will come with the people who respect you for who you are. that is the only kind of popularity that really counts. 【文章大意】本文鼓励青少年要有自己独立的思维, 不要依赖父母或随波逐流。1. in this passage, the author wants to tell. a. teenagers how to learn to decide things for themselvesb. readers how to be popular with people aroundc. parents how to control and guide their childrend. people how to understand and respect each other【解析】选a。主旨大意题。根据第一段中“at your age you ought to be growing away from your parents. you should be learning to stand on your own feet. ”可知a项正确。2. according to the author, many teenagers think they are brave enough to act on their own, but in fact, most of them. a. have much difficulty understanding each otherb. lack confidencec. dare not cope with problems single-handedd. are much afraid of getting lost【解析】选c。细节理解题。根据第一段最后一句及第二段内容可知, 他们想我行我素, 但结果却随波逐流。3. what does the author think of advertisements?
