One school night this month I walked quietly up to Alexander, my 15-year-old son, and touched his cheek gently in a manner I hoped would seem casual．A year ago he would have ignored this disturbance but now he reacted impatiently and leaned back to his computer screen．

I made a mistake: breaking into my teenager's personal space. “The average teenager has pretty strong feelings about his privacy," Lara Fox and her friend Hilary Frankel told me. Mr．Frankel and Mr．Fox, both 17, are the authors of Breaking the Code, a new book that seeks to bridge the generational divide between parents and adolescents．It is being promoted by its publisher as the first self-help guide by teenagers for their parents, a kind of "Kids Are From Mars, Parents Are From Venus" that explains the language and actions of teenagers．The girls dealt with issues including hanging out late, money, school pressures, smoking etc．

Personally, I welcome their opinions．The most common missteps in interacting with teenagers arise from the war between parents exercising their rights to know what goes on under their roof and teenagers firmly guarding their privacy．Teenagers can be quick to interpret their parents' remarks and respond with anger that masks their vulnerability （脆弱）. Ms Fox said, "What we want above all is your approval．Don't forget, no matter how much we act as if we don't care what you say, we believe the things you say about us．"

Nancy, a New York child-raising expert said she didn't agree with everything the authors suggested but found their arguments reasonable．"When your kids are saying, ' You don't get it, and you never will, ' there are lots of ways to respond so that they will listen and that is what the writers point out．"

" My parents helped me see that, " Mr．Fox told me, " even though they used to stay out late and ride their bicycles to school, times have changed and the way parents educate children is different．These days there is a major fear factor in bringing up kids．Parents worry about their child crossing the street．" The writers said they hoped simply to throw light on teenage thinking．

汽车排出的废气是滨河区一个严重的污染问题，在滨河区的桥上收取通行费将会减少汽车行驶的里程数。尽管如此，仍无法降低总的污染水平，因为在收费亭排起了长队，而汽车停着不走时会比其在行驶状态下放出更多的废气。
上面的论述依赖于下面哪一个假设

A．因为缴费排队产生的多余废气相当于或超过因汽车行驶里程数减少而减少的汽车尾气。

B．平均来讲，汽车在滨河区停着不走的时间比处于其他行驶状态时间长。

C．在桥上增加的汽车尾气不会严重影响大气污染，因为在滨河区很少有司机经常驾车过桥。

D．减少汽车废气排放不是降低空气污染的最有效办法。
