测，但could偶尔可用于肯定推测。may/might表推测时一般用于肯定句
或否定句，可对现在、过去或将来的事情进行推测，语气不很肯定，
译为“可能……”。

done”。

但实际上没有做到”，此时不能用may或can。
He might have given you more help，even though he was very busy.即使再忙，他也可能再多给你一些帮助的。
三、情态动词表责备语气
情态动词should，ought to，could，might，need等常用来表示说话人
对过去事情的不满或遗憾，带有较强烈的责备语气。
1．should (ought to) have done “本应该……”，表示过去应该做而
(实际)没有做的事情，含有责备或遗憾的语气，其否定形式为
“should not/ought not to have done”。

一、情态动词表推测的三种句式
1.在肯定句中一般用must (一定)，may（可能），might / could（也许，或许）。
（1）He must/may/might know the answer to this question?
他一定/可能/也许知道这个问题的答案。
（2）It is cold in the room. They must have turned off the heating.
屋里很冷，他们肯定把暖气关了。
2.否定句中用can’t / couldn’t(不可能), may not/might not(可能不)。

（1）Could he have finished the task? 他可能把任务完成了吗？
（2）Can he be at home now? 他现在能在家吗？
注：以上三种句式中情态动词的语气按程度都是依次递减的。Might, could并非may, can的过去式，而表示语气较为委婉或可能性较小。
二、情态动词表推测的三种时态
1.对将来情况的推测，用“情态动词 + 动词原形”。
（1）She must / may / might / could arrive before 5. 5:00前她一定/可能/也许到。
（2）She must/may/might/could walk miles and miles among the hills without meeting anyone.
她一定/可能/也许会在山里一连走好几英里而遇不到一个人。

门锁着，他不可能/可能不在家。
（3）Can / Could he have gotten the book？
难道他找到书了吗？
注：情态动词 should /ought to表推测时，意为“想必会，理应……”但与“have +过去分词”连用时，则又可构成虚拟语气意为“本应该做某事却没做”。例如：
（4）It’s seven o’clock. Jack should/ought to be here at any moment.
现在七点钟了，杰克理应随时到达。（推测）
（5）She should / ought to have attended your birthday party, but she had to look after her mother in hospital. （虚拟） 她本该出席你的生日晚会的，可是她得在医院照顾她妈妈。
（6）Tom should not /ought not to have told me your secret, but he meant no harm. （虚拟）
