3.选项特点
1.正确选项特点
(1)原文的同义替换---同义词，近义词替换；句型转换；词性转换；高度概括；正话反说：例如，原文用双重否定，选项用肯定句式。
(2)以主题为导向，有很多选项刚好落在段落主旨句中。
2.干扰项特点：
(1)以偏概全：句中部分正确，部分错误。
(2)答非所问，无中生有：符合常识，但不是文章的内容。
(3) 偷换概念：与原句的内容极为相似，但程度上有些变动，将文中并非绝对化的内容绝对化。
例如：21. According to the first paragraph, peer pressure often emerges as（)2012text1
[A] a supplement to the social cure
[B] a stimulus to group dynamics
[C] an obstacle to school progress
[D] a cause of undesirable behaviors
Come on –Everybody’s doing it. That whispered message, half invitation and half forcing, is what most of us think of when we hear the words peer pressure. It usually leads to no good-drinking, drugs and casual sex. But in her new book Join the Club, Tina Rosenberg contends that peer pressure can also be a positive force through what she calls the social cure, in which organizations and officials use the power of group dynamics to help individuals improve their lives and possibly the word.
解析：选D, 因为本题是细节题的同意替换：cause=lead to; undesirable=no good; behaviors=drinking,drugs and casual sex。A，B是Rosenberg个人的观点，且是文中句子的偷换概念，C在本段是无中生有。
