阅读成绩不理想?除了词汇量差，句子结构看不懂这些硬伤，其实你还忽略了标点符号里隐藏的玄机，这些标点符号对于提升阅读做题速度、迅速找出答案也是大有帮助的......一起看看吧~

　　逗号

　　用于分割并列成分。考研重点：两个逗号之间，或者一个逗号之后，如果是补充说明成分时，跳过不看。Eg. Some huge American industries, such as consumer electronics, had shrunk or vanished in the face of foreign competition.

　　句号

　　①用于陈述句，表示一个句子的结束， 起分割切分句子作用。

　　②用于某些缩略词之后。比如Mr.、 Ms.、 etc。等等。如果句号作为简写符号使用，那么这个词语简写前后面的符号应该照常写上，因为简写号并非句号，也不遵循句号的语法。比如Entreprise Co., Ltd或者I invited Tom, Jerry, etc。.(注意两个点)。

　　③用作小数点

　　问号

　　考研英语阅读文章中的问号一般都是设问的功能，只问不答，答案不言自明。Eg1. 考研难道没有价值吗?另外，如果开篇就是问句，那么则属于问题答案型文章，对问题的回答就是全文主旨。

　　冒号

　　冒号前后是从抽象到具体的过程，后面进一步补充说明前面的内容。

　　Eg.1997 passage 3 Q2

　　60. The word "pervasive" (Line 1, Paragraph 2) might mean ________。

　　[A] widespread [B] overwhelming

　　[C] piercing [D] fashionable

　　We live in a society in which the medicinal and social use of substances (drugs) is pervasive: an aspirin to quiet a headache, some wine to be sociable, coffee to get going in the morning, a cigarette for the nerves。

　　分号

　　前后是并列关系，包括结构上并列和语义上的并列。

　　For us, this means that evolution is over; the biological Utopia has arrived. (2000 Passage2)

　　引号

　　①引用 ②强调 ③讽刺

　　Eg1 "Scientific" creationism, which is being pushed by some for "equal time" in the classrooms whenever the scientific accounts of evolution are given, is based on religion, not science。

　　括号

　　①解释说明生词。②补充说明

　　Drugs (substances) that affect the central nervous system and alter perception, mood, and behavior are known as psychoactive substances. (1997，Text 3)

　　破折号

　　①一个破折号后面起补充说明或评价判断。

　　I am an idiot - the stupidest kind of all。

　　"This book stands for reason itself。" And so it does - and all would be well were reason the only judge in the creationism/evolution debate。

　　②两破折号之间其补充说明，可先跳过不看。

　　In Australia-where an aging population, life-extending technology and changing community attitudes have all played their part-other states are going to consider making a similar law to deal with euthanasia。

　　省略号

　　英文中的省略号的作用和汉语是一样的。当省略号在句围并且有下文时，应该打四个点，最后一个为句号。如：And it flew further, and further, and further.... Jorge smiled and turned back。当省略号在句尾并作为语气延长的作用时，应使用修辞前的标点，如：Do you love me...?其余情况下使用三个点。如：The Martians...they just...just bombed our...our town, please send...more.
