初中英语语法专题: 情态动词(PDF版)
情态动词情态动词的特点:1.从词义的角度来看,情态动词有其自身的词汇意义,如用来表示可能、建议、愿望、必要、允许、能力、怀疑等等,以表示说话者对某种行为或状态的看法或态度。
从在谓语中的作用的角度来看,与助动词一样,情态动词在句中不能单独作句子的谓语,而必须和实义动词一起构成复合谓语。
1.最基本的情态动词有五个:can,may,must,shall和will;2.除了must以外,其他四个情态动词都有对应的一般过去式,分别是:could,might,should和would;3.这五个情态动词都有对应的情态动词短语,分别是:be able to,be allowed to,have(got)to,be supposed to/ought to和be going to。
需要注意的是,四个情态动词的过去形式could,might,would和should只是在形式上是can,may,will 和shall的过去式,而在意义上并不是完全对应于can,may,will和shall。
具体来说,一方面,现在式和过去式这两类情态动词的意义并不完全对等。
例如,can和could的意义并不完全等同,它们既有共同的用法,如表示能力,也有各自不同的用法。
另一方面,这四个过去形式的情态动词并不一定表示过去的时间(实际上通常都不是)。
情态动词的用法大致可以分为以下两大类:一类是各个情态动词有各自基本的用法,比如,can意为能够,must意为必须,should意为应该等。
常用“情态动词+动词原形”的结构一类是表示“可能性”或“推测”,即表示人们对于某件事情发生的可能性大小所作的判断。
常用“情态动词+动词原形”(对现在进行推测)和“情态动词+完成式”(对过去进行推测)结构情态动词各自的基本意义及用法:1.can与could用法对比点can could1、表“能力”Can you lift this heavy box?I couldn’t understand what he said at all.2、表“许可”You can use a different materialinstead.He said I could borrow his bike.3、“怀疑”No,no,it can’t be true.What on earth can this mean?We thought the story could not be true.How could you be so careless?4、can与be able to 区别1.could代替can,表示语气更为婉转。
