Question

8．Having a teenager at home can be a real headache．Many teenagers smoke，wear strange hairstyle and even fight．Basically （基本上），they are often taking risks．
Earlier studies have shown that teenagers are more likely to make irrational decisions than people from any other age group，including children and adults．Is it that teenagers are too young to tell right from wrong？Not really．So what's the reason？
According to Laurence，a teacher from a US university，the reason is that teenagers care a lot about how their peers （同齡人） view them-that is"peer influence"．
As children enter their teenage years，they spend more time with their friends and classmates，and also they care more about what they think of them．This makes teenagers make decisions without thinking about the costs．
In a test，a group of teenagers were asked to play a video driving game．When they played with their friends watching around them，they took more chances and drove more carelessly because that would increase their possibility of winning．But when they played alone，they drove more safely．
Why do peers have such a big influence on teens'behavior？
As Laurence sees it，a teenager's brain is like a car with a good accelerator （油門） but a weak brake （剎車）．The"accelerator"is fully developed by teenage years while the"brake"is still not fully developed．When teenagers are watched by their peers，they usually push hard on the accelerator．With their weak brake，it is likely that they are going to end up in an accident．
But the good news is that a violent （暴力的） teenager doesn't necessarily become a violent adult．About two-thirds to three-quarters of violent youth grow out of it．"They get more self-controlled．"

Answer 1

分析 先前的研究已經(jīng)表明，青少年比任何其他年齡組的人更容易做出非理性的決定，這是青少年太年輕不能明辨是非？不完全是．那么是什么原因？根據(jù)勞倫斯的研究原因是青少年關(guān)心同齡人如何看他．但好的消息是，暴力青少年不一定成為一個(gè)暴力的成人．大約三分之二到四分之三的暴力青年長(zhǎng)大后能自我控制．

解答 31．B 詞義猜測(cè)題．根據(jù)下一句：Is it that teenagers are too young to tell right from wrong？是不是青少年太年輕，不能分辨對(duì)與錯(cuò)？可以推斷出此處句意為：先前的研究已經(jīng)表明，青少年比任何其他年齡組的人更容易做出非理性的決定，故選B．
32．D 細(xì)節(jié)理解題．根據(jù)第三段末the reason is that teenagers care a lot about how their peers （同齡人） view them可知原因是青少年在意他們的伙伴怎么認(rèn)為的．故選D．
33．A 細(xì)節(jié)理解題．根據(jù)第七段第一句As Laurence sees it，a teenager's brain is like a car with a good accelerator （油門） but a weak brake （剎車）．可知正如勞倫斯所看到的那樣，一個(gè)十幾歲的孩子的大腦就像一輛有著良好油門的汽車，但卻是一個(gè)虛弱的剎車．這好似一個(gè)比喻．故選A．
34．D 推理判斷題．根據(jù)短文內(nèi)容可知青少年更加關(guān)注短期效益，所以該選D．
35．C 細(xì)節(jié)理解題．根據(jù)短文最后About two-thirds to three-quarters of violent youth grow out of it．"They get more self-controlled．可知大約三分之二到四分之三的暴力青年長(zhǎng)大了．"他們會(huì)有更多的自我控制．故選C．

點(diǎn)評(píng) 做題時(shí)要在理解好文意的基礎(chǔ)上，與題目有機(jī)的結(jié)合，從文章中找到相關(guān)細(xì)節(jié)性的句子與選項(xiàng)細(xì)細(xì)比對(duì)，進(jìn)行選擇或推理判斷，選出符合文章內(nèi)容的正確選項(xiàng)．做題注意靈活，有時(shí)可采用排除法或直選法確定出最終答案．
