18、必要等。情态动词无人称和数的变化,其后接的动词需用原形,否定式实在情态动词后加上not。当我们想表达可能发生某事以及某人可能做某事时,可以用may/might表示。2.may和might 用于一般疑问句中,表示委婉的请求;肯定回答用may;否定回答用mightE.g. May I use your pencil?可以用你的铅笔吗? Yes, you may.是的,可以 No, you mustnt.不,不行3.may和might 表示推测时,只能用于陈述句中,might暗示可能性更小E.g. She may not be working now. 现在可能她没有在工作 John might b
19、e at home now. 约翰现在可能在家4.对过去发生的事情的可能性作出判断应用may/might have done,用might比用may所表示的可能性更小E.g.She may/might have gone to the cinema. 她可能去电影院了 They may/might not have received our telephone. 他们可能没有接到我们的电话5. might 是 may 的过去式,但表示可能性时没有很大区别,只是表示一般将来的可能性时,might 比 may 的可能性要小。因为 might 和 may 都是情态动词,所以,他们后面应加动词原形,即
20、:S (主语) + might/may + do sth.【拓展】possible 表示可能性possible, possibly, probably 的常用结构:It is possible that . It is possible to do sth. S (主语) + will probably / possibly + do sth. probably表示的可能性比possibly要大。【即学即练】 1. Tom, you _ play with the knife. You _ hurt yourself. A.wont; cant B.mustnt; may C.shouldnt
