1、-情态动词can-may-must辨析-第 200 页情态动词can、may、must的横向辨析 英语情态动词对中国学生来说，确实是一个费解的语法项目。其主要原因是中国学生缺少语境和意境；其次，课本和语法书只是逐个讲述每个情态动词的用法，缺少对每个情态动词之间意义上的横向比较。为了帮助读者清晰地区分它们之间的差异，达到正确运用的目的，笔者就“can、may、must”三个情态动词进行横向对比。 一、表示“能力”。l只可用can（could）。may、must则无此种含义。例：I can swim now，but I couldnt last year. Can you play me pian

2、o？Yes，I can2can（could）适用于各种句型和人称。例：肯定句：I（You，He）can swim. 否定句：I（You，He）cant swim. 疑问句：Can I（you，he）swim？二、表示“请求”或“许可”。can、may、must都可用，但语气和程度不同。1can（could）用于各种句型和大部分人称。例：肯定句：You（He，We）can go now否定句：You（He，We）cant go now疑问句：Can I（you，he）go now？Yes，you can（No，you cant）2may（might）用于各种句型，但在肯定句和否定句中不用于第一人

3、称；在疑问句中不用于第二人称。 例：肯定句：You（He）may go now否定句：You（He）may not go now疑问句：May I（he）go now？正规回答：（表定）Yes，you may( 否定）No，you may not（No，you cantNo，you mustnt口语化回答：（肯定）Yes，please（Certainly）（否定）No，please dont（No，of course not）3must用于各种句型和大部分人称。 例：肯定句：I（You，He）must go now否定句：You（He）mustnt go now 疑问句：Must（you，he

4、）go now？肯定回答：Yes，you must. 否定回答：No，you neednt（No，you dont have to） 4试比较：You may not smoke here（不可以）语气轻You cant smoke here（不能）重You mustnt smoke here（决不可）最重三、表示“可能”、“或许”和“推测”之意。can、may、must都可用，但语气和程度不同。lcan （could）常用于否定句和疑问句中，could表示的“可能性”更小。例：否定句：It couldnt be him，for hes at the library疑问句：Can he hav

5、e gone out？What can they be doing now？2may（might）用于肯定句和否定句中，might表示的“可能性”更小。例：肯定句：He may be right否定句：She might not have e yet3must用于肯定句中。例：You must be very hungry（对现在情况猜测）Asia must have met a fairy（对过去事实的猜测）Everything is clean and tidySomeone must have cleaned my room（同上）4试比较：He might not have gone

6、out（或许没有） He cant have gone out（不可能） He must have been in the room（一定、准是） 以上三句可能性逐渐加大至肯定。练习题：一、说明下列句中情态动词的含义。（A能力；B许可；C猜测）。 （ ） l. “You must write more neatly,” said the teacher （ ） 2. Hes not in the officeHe must have gone to the meeting （ ） 3. Visitors mustnt move and touch the exhibits （ ） 4. The
