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。
2、若无逗号，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.
3、 being 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
4、than, David. 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 speak B. were they speaking C. are they speaking D. have they been
5、speaking【析】C。前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
6、 anywhere. Well. He _ 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
7、例外。（三） 帮助分析语义结构。例如：Ive never seen anyone run so fast _ David go. A. just watch B. just to watch C. 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. mustnt C. neednt D. 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 go C. not going D. 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。
