情态动词must__can__could__may__might表推测的用法 (2)
情态动词must, can, could, may, might表推测的用法：情态动词中的must, can, could, may, might都表推测。
其中must的可能性最大，can / could次之，may / might最小。
具体用法如下：1. must的用法（1）表示推测“可能性”时，意思是“一定、准是”，语气较肯定，较有把握。
He must be American. = It is certain that he is American. 他准是个美国人。
（2）must表推测只能用于肯定句。
假如要表示“一定不、肯定不”的意思时，应用can`t,如询问某种可能时，应用can。
He must know my address. 他肯定知道我的地址。
（一定）He can`t know my address. 他肯定不知道我的地址。
（一定不）Can he know my address? 他知道我的地址吗？（询问可能性）（3）must表示推测时，能够推测现在/正在发生的动作/过去发生的动作。
He must have a car now. （现在）他一定有辆小汽车。
He must be doing his exercises in the classroom.（正在实行）他一定在教室里做练习。
He must have finished the work.（过去发生）他一定已完成了工作。
注：must表示推测时很少用于将来的情况。
一般不用He must come tomorrow.可用It`s certain / I`m sure that he will come tomorrow. （4）在反意疑问句中，当附属局部含有表示推测意义的must时，疑问局部的助动词应与must后面的动词在非推测情况下的用法保持一致。
He must be a worker, isn`t he? （现在）他准时个工人，是吗？It must have rained last night, didn`t it? （过去）昨晚一定下雨了，是不是？You must have learned English for many years, haven`t you? （完成时）你一定学了好多年英语，是吗？2. can / could的用法（1）can表示推测“可能性”时，往往用于否认句或疑问句。

情态动词10条学习要点“could have 过去分词”用法全面归纳讲义 高考英语语法复习
2023年高中英语语法：情态动词10条学习要点“could+have+过去分词”用法全面归纳有关情态动词的10条学习要点1. 弄清基本语法特点情态动词就是表示说话的语气或情态的动词。
常见的情态动词有can, may, must, need, dare, shall, will, should, ought to, have to, used to, had better, would rather等。
情态动词具有以下3个特点：(1)情态动词后面接动词原形并与动词原形一起构成谓语。
(2)情态动词虽有时态的变化，但却没有人称和数的变化，即情态动词不会因为主语的人称或单复数的不同而用不同的形式。
(3)变为疑问句或否定句时不需要助动词，而是将情态动词移至主语前变为疑问句，直接在情态动词后加not，构成否定句。
2. 弄清表示能力的can / could和be able to的用法(1)can表示具有某种能力或技能，意为“能，会”。
如：Who can answer this question? 谁能回答这个问题？(2)can 的过去式为could，但它通常只表示过去一般性能力，不表示过去特定场合下的能力，遇此情况要用was [were] able to。
如：I could run faster then. 我那时能跑得更快一些。
They were able to jump into the sea before the boat was blown up. 他们在船爆之前跳入海里。
3. 弄清表示许可的can / could / may / might / must的用法can / could / may / might均可表示许可，只不过may较侧重讲话人的许可，而can较侧重客观情况的许可；could / might的语气比can / may更委婉、客气；在答语中表示允许别人做某事要can / may，不能用could / might。
