1、做好单选题，标点要重视纵观历年高考英语试题可以发现，标点符号在句子中直接或间接地影响了考生对单项填空题的作答。因此，大家在做题时，要特别重视标点符号在句子中所起的作用。请看下面各题。一、 逗号（一）用来引出同位语或非限制性定语从句。例如：1. Meeting my uncle after all these years was an unforgettable moment, _ I will always treasure. A. that B. one C. it D. what【析】 B。 one指代 moment作同位语， I will always treasure为定语从句。若无逗
2、号，则选A，that 引导定语从句并在从句中作宾语。2. Jim passed the driving test, _ surprised everybody in the office.（浙江2005）A. which B. that C. this D. it【析】A。根据逗号确定，本题考查非限制性定语从句。which引导从句并指代前面的整句话。（二） 用来引出分词或独立结构在句中作状语。例如：1. I send you 100 dollars today, the rest _ in a year. A. follows B. followed C. to follow D. being
3、 followed【析】C。逗号后是状语。the rest和不定式构成逻辑主谓关系，不定式在此表示将来的动作。2. Alice returned from the managers office, _ me that the boss wanted to see me at once. A. having told B. tells C. to tell D. telling【析】D。telling . 在此句中作伴随状语。分词作状语常用逗号和其它成分分开，而不定式则不用。（三） 用来分开插入的语句。例如：John plays football _, if not better than, D
4、avid. A. as well B. as well as C. so well D. so well as【析】B。 if not better than是插入语。句意为：John 即使踢得不比David 更好，也至少和David 踢得一样好。故选B。二、 句号（一） 前一句为后一句提供关键信息。例如：Listen to the two girls by the window. What language _? A. did they speakB. were they speakingC. are they speakingD. have they been speaking【析】C。前
5、一祈使句决定了后句动词表示的动作现在正在发生，所以用现在进行时。（二） 后一句为前一句提供关键信息。例如： Lucy doesnt mind lending you her dictionary. She _. Ive already borrowed one.A. cant B. mustnt C. neednt D. shouldnt【析】C。由下文Ive already borrowed one可知，“她不需要做”。三、 破折号（一）为上句提供关键信息。例如： Do you know where David is? I couldnt find him anywhere. Well. H
6、e _ have gone far his coats still here. A. shouldnt B. mustnt C. cant D. wouldnt【析】C。根据句意“他的外套还在这里，所以他肯定没走多远”推断选cant。（二）提供进一步信息，作进一步解释。例如： Everyone was on time for the meeting _ Chris, whos usually ten minutes late for everything. A. but B. only C. even D. yet【析】C。破折号用来说明Chris也不例外。（三） 帮助分析语义结构。例如：Iv
7、e never seen anyone run so fast _ David go. A. just watch B. just to watchC. just watching D. just having watched【析】A。破折号起说明举例作用，相当于冒号，其后应为一个句子，对前句解释说明。四、 感叹号感叹号主要用来加强语气，表示说话者强烈的感情色彩。例如：Tom, you _ leave all your clothes on the floor like this!A. wouldnt B. mustntC. needntD. may not【析】B。感叹号加强了命令的口吻，表达说话者的强烈要求，因而选mustnt。五、 冒号冒号可用于对前面内容的介绍或解释。例如：There are eight tips in Dr. Rogers lecture on sleep, and one of them is: _ to bed early unless you think it is necessary. A. doesnt go B. not to goC. not goingD. dont go【析】D。 冒号后的句子解释其中的一个tip，所以应选祈使句dont go。
