1、2021届新高考英语语法微专题培优复习情态动词与have done知识点总结与练习(含解析)情态动词在高考题中的考察非常直接，主要考察以下两方面：1、情态动词的本义2、情态动词与have done咱们今天先把简单的解决了，就是情态动词与have doneo这东西在 考试里就俩方向，一个表示对过去的推测，一个表示对过去的虚拟。注 意,只要情态动词加了 have done , 一定表示过去的事。1、表示对过去情况的推测must have done / cant have donecould have done / couldnt have donemight (may) have done / m
2、ight (may) not have done三者的语气按照must could might的顺序依次递减，表示对 于推测准确性的把握在逐步降低。当然，在题目当中我们并不需要掌握三 种语气的差异，只要观察题目中有没有出现推测的证据，或者证据是否确 凿，即可作出语气强或弱的判断。有证据，就强；没证据，就弱。2、表示对过去情况的虚拟should have done本应该责备语气shouldnt have done本不应该责备语气could have done本可能遗憾/惋惜语气couldnt have done本不可能 意外/惊喜语气neednt have done本不必 多余/不必要语气表示虚
3、拟时，句中一定可以加入本来”这样的口吻。请注意，每 种虚拟都有自己的使用场合，进而传达出在该场合下需要体现的语气和态 度。把两方面合并在一起，我们就会发现，情态动词+ have done的结 构，其实可以这样来方便记忆：must / might (may)推测+could推测/虚拟4-should / need 虚拟must和might肯定是推测，should和need肯定是虚拟，只有 could 一个同时身兼两种功能，所以遇到的时候要注意判断。当然，还有另外需要注意直接排除的：mustnt / can / need这三种形式，后面不与have done 一起使 用。练习在看题之前，重新强调一
4、下：情态动词+ have done表示过去推测用 must / might ;虚拟用 should / need ;二者皆可的只有could ;mustnt / can / need 和 have done 不一起用。另外，句意是推测还是虚拟必须得自己能看出来，这是硬性要求。在 现在的语法填空里，不会让各位去填情态动词,所以以下的题目并不需要 各位去自测，而是需要各位能够结合题目选择检验自己对句子的正确理 解。简而言之,能看懂句子意思和情态动词+ have done的意思即可。He has no idea what the book is about. He have read it very
