情态动词表推测用法总结及专项练习1.can / could用于表推测的用法(1) 从使用句型上看，can 通常只用于否定句或疑问句，一般不用于肯定句，而could 可用于肯定句、否定句和疑问句。

两者没有时间上的差别，只是could 比can 更委婉，更不确定。

如：It can’t [couldn’t] be true. 那不可能是真的。

What can [could] they be doing? 他们会在干什么呢?We could go there this summer. 今年夏天我们可能要去那儿。

注：can 有时也用于肯定句中表示推测，主要用于表示理论上的可能性(即从理论上看是可能的，但实际未必会发生)，或表示“有时”之意。

如：Even experienced teachers can make mistakes. 即使是有经验的教师也可能出错。

She can be very unpleasant. 她有时很令人讨厌。

(2) 从时间关系看，对现在或将来情况作推测，后接动词原形；对正在进行的情况作推测，后接be doing 结构；对过去情况作推测，后接动词完成式。

如：He could have gone home. 他可能已经回家了。

He can’t [couldn’t] have understood. 他不可能理解了。

Why does he know this? Can [Could] someone have told him about it? 他怎么知道? 会是哪个人告诉他了吗?(3) “could+完成式”除表示对过去的推测外，还有以下重要用法：①表示过去没有实现的可能性，常译为“本来可以”。

如：I could have lent you the money．Why didn’t you ask me? 我本来可以借这笔钱给你的。

你为什么不向我提出?②用来委婉地责备某人过去应该做某事而没有去做，常译为“本来应该”。

九年级英语表推测语气的讲解与练习表推测时，英语中只使用must,may,might,maynot和can't。

这五个表达的语气依次递减：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。

HemustbeAmerican.=ItiscertainthatheisAmerican.他准是个美国人。

（2）如询问某（3）注：（4must后（1）can在（2）can/can’t后可接进行时/完成时，表示对现在发生的动作或过去发生的动作进行推测。

Theycan’tbereadinginthelibrary.他们一定不在图书馆读书。

Hecan’thavegonetoShangh aiforIsawhimaminuteago.他不可能去了上海，我刚才还看见他。

It’ssolate.Wherecanshehavegone?天晚了，她可能去哪儿了呢？（3）在反意疑问句中，当陈述部分含有表示推测意义的can’t时，疑问部分的助动词应与can’t 后面的动词在非推测情况下的用法保持一致.Hecan’tbeateacher,ishe?他不是教师，是吗？Shecan’thavefinishedherhomework,hasshe?她一定没有完成家庭作业，是不是？could可用于表示某事有可能发生表示可能性不大的推测。

意思相当于may/mightDon’teatit.Itcouldbepoisonous.不要吃它，可能有毒。

Theplanecouldbedelayedbyfog.飞机可能会因为雾晚点。

（5）could还可以用于表示客气、委婉、礼貌的请求语气。

表推测的情态动词及其用法以下是 7 条关于表推测的情态动词及其用法：1. “might”，它就像一个小小的猜测小精灵。

比如说，“It might rain later.”（等会儿可能会下雨。

），就像你觉得天上有点阴阴的，感觉可能会下雨，但又不是特别肯定。

2. “could”呀，可神奇了呢！就像“ He could be at the park.” （他可能在公园呢。

），你觉得他有在公园的可能性，但又不是百分之一百确定。

3. “may”呢，是个不太确定的小天使哟！“She may come to the party.”（她也许会来参加聚会。

），是不是感觉你抱有希望她会来，但又不敢打包票呀？4. “must”这个家伙很肯定哦！“He must be very tired.”（他一定很累。

），就好像从一些迹象能明显感觉到他就是很累，没有别的可能啦。

5. “should”有时候就像是一个合理的推测！比如“ They should behere by now.” （他们现在应该到这儿了。

），是那种根据正常情况推测的感觉呀。

6. “would”就像一种假设的可能性。

像“ I would go if I had the time.” （要是我有时间我就会去。

），你懂那种如果怎样就会怎样的感觉吧？7. “ought to”也很有用呢。

“We ought to have more food for the party.”（我们应该为聚会准备更多食物。

），是不是感觉根据常理应该这么做呀？我觉得啊，这些情态动词让我们的表达更丰富、更灵活，能更好地传达我们心中那种不确定或者推测的感觉，真是太奇妙啦！。
