2、别具有相同功能的，意思相近的情态动词特征用法是突破这一难点的特效举措。故而，现将其结构用法小节于后，敬供研析。1. can / cannot + have +done“can / cannot + have +done”结构，表示“可能已经做了；不可能做了”的事。指对过去发生的行为的怀疑或不肯定，通常用在否定句或疑问句中。例：Where can they have gone?他们可能已经去了什么地方？例：He cannot have stolen my MP4 player.他不可能偷我的MP4播放机。2. could + have + done“could + have +done”结构，用

5、gh you were tired.你本来可以帮他学好英语的，尽管很累。5. neednt + have + done“neednt + have + done”结构，用于否定句中，表示“不必要做的事而已经做了”；但 didnt need to do sth.意为“没必要做而实际上也没有做的事”。例：You neednt have apologized to him for nothing yesterday.你没有必要给他道歉，因为昨天什么都没有做。6. must + have +done “must + have +done”结构，用于肯定句，表示对过去已经发生的行为进行肯定的推测，意为“

7、他不该闯红灯。I should have written to you earlier, buy Ive really been busy. 我本该给要你早点写信，可后来真的是太忙了。8. have better + have + done“have better + have + done”结构，表示用于事后的建议，有一点轻微的责备语气，意为“当时最好做了某事”，其否定式had better not have done则表示相反的含义。例：You had better have come earlier.你当时最好早一点来。9. would like/love to + have + don

8、e“would like/love to + have + done”结构，表示“过去愿意做某事而实际上未做成”。例：I would like to have seen you off at the station yesterday morning but I was too busy.我昨天很想到车站来送你，可就是没有空。10. would rather + have + done“would rather + have + done”结构，用于肯定句，表示“当时宁愿该做了某事”，否定式would rather have done则表示含义相反，两者均含有“后悔”之意。例：I would
