12．For many parents，raising a teenager is like fighting a long war，but years go by without any clear winner．Like a border conflict between neighboring countries，the parent-teen war is about boundaries：Where is the line between what I control and what you do？
Both sides want peace，but neither feels it has any power to stop the conflict．In part，this is because neither is willing to admit any responsibility for starting it．From the parents'point of view，the only cause of their fight is their adolescents'complete unreasonableness．And of course，the teens see it in exactly the same way，except oppositely．Both feel trapped．
In this article，I'll describe three no-win situations that commonly appear between teens and parents and then suggest some ways out of the trap．The first no-win situation is quarrels over unimportant things．Examples include the color of the teen's hair，the cleanliness of the bedroom，the preferred style of clothing，the child's failure to eat a good breakfast before school，or his tendency to sleep until noon on the weekends．Second，blaming．The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong．Third，needing to be right．It doesn't matter what the topic is-politics，the laws of physics，or the proper way to break an egg-the point of these arguments is to prove that you are right and the other person is wrong，for both wish to be considered an authority-someone who actually knows something-and therefore to command respect．Unfortunately，as long as parents and teens continue to assume that they know more than the other，they'll continue to fight these battles forever and never make any real progress．

分析 本篇文章为议论文．家长和孩子之间的冲突没有最后的赢家．导致冲突的原因有三个：一是对一些诸如头发的颜色、房间的清洁、衣服的款式、不好好吃早餐以及睡懒觉等等这些鸡毛蒜皮的小事的争吵，二是互相指责，认为对方不好的态度是什么都乱套了的根本原因，三是都认为自己的观念点是对的，这样才能取得对方的尊重．
解答 25-28 BACC
25 B 推理判断题．由文章第一段中"the parent-teen war is about boundaries：Where is the line between what I control and what you do？"可知，家长与孩子之间的冲突好比两国之间的争端一样，主要就是要分出界线出来：我（家长）的控制线在哪儿？你（孩子）是不是没有越雷池半步？故选B．
26 A 推理判断题．文章的第二段Both sides want peace，but neither feels it has any power to stop the conflict．说双方都希望相安无事，但是双方又觉得平息争端无能为力，原因是都不愿意承认是自己挑起了争端，家长认为孩子没有道理，孩子这一方也是一样．因此答案选A：孩子把争端的起始归咎于父母．
27 C 细节理解题．由文章最后一段的"both wish to be considered an authority--someone who actually knows something--and therefore to command respect．"可知，双方都认为自己是对的，就是要对方觉得自己是权威的一方，这样对方就会尊重自己．故选C．
28 C 推理判断题．本篇文章第三段In this article，I'll describe three no-win situations that commonly appear between teens and parents and then suggest some ways out of the trap．通过举例来说家长和孩子之间的冲突的一些现象和原因，接下来应该讲解决这些冲突的方法了．故选C．
