　　—Well，I don’t know.It might do. should用来表示推测时意为“应该”，即含有“按道理来说应当如此”的意思。 There shouldn’t be any difficulty about passing the road test since you have practiced a lot in the driving school. 1．(2016·高考江西卷)Life is unpredictable; even the poorest ________ become the richest. A．shall

　　B．must C．need

　　D．might 解析：考查情态动词。句意：生活是不可预料的,甚至最贫穷的可能变成最富有的。根据unpredictable(不可预料的)可知，本题应该选might(可能)。 D

　　2．(2016·高考天津卷)No one ________be more generous; he has a heart of gold. A．could

　　B．must

　　C．dare

　　D．need

　　三、情态动词＋have done 情态动词＋have done 用法例句 must have done may/might have done 表示对过去已经发生的行为进行推测,意为“一定做了某事”。 Harry is feeling uncomfortable.He

　　must have drunk too much at the party last night. 表示对过去已发生行为的推测，意为“也许/或许已经(没有)……”。一般用于肯定句或否定句中。 Sorry，I’m late.I might have turned off the alarm clock and gone back to sleep again. 情态动词＋have done 用法例句 can...have done/cannot have done could have done 表示对过去发生的行为的怀疑和不肯定,通常用在否定句和疑问句中。(can换成could时语气较委婉) ①I can’t find him anywhere.Where can he have gone？ ②The boy can’t have finished reading the book so soon because it is difficult even to an adult. 本来能够而没有做 (2016·高考福建卷)He could have gone on regretting it, as too many of us do. 情态动词＋have done 用法例句 might have done should/ought to have done 表示本来可能……，但实际上没有发生的事情。 You should not swim in that sea.You might have been eaten by a shark. (1)用于肯定句时，表示本该做某事而实际上未做；(2)用于否定句时，则表示不该做的事反而做了。 ①You shouldn’t have done it so carelessly.
