the worldGrammar 情态动词表示
“推测”的用法英语中，情态动词can / could, may / might, must / can, would / should 等都可以表示“推测”。具体用法如下：can 表示推测时，可能性比较大，常用于疑问句或否定句中，不用于肯定句中， 意为“不可能”。表示一种有把握的推测。表示否定时， can’t语气最强。1. can 和could It can’t be Mr Li. He has gone to Nanjing already. They can’t know the answer. Let me explain it to them. That can’t be her husband. She is still single. could 表示推测时，可以用于否定句中，也可以用在后面跟动词原形的肯定句中。表示可能性不大的推测，意思相当于may / might。 Anything could happen if you do not obey the rule. It could be true. But I still doubt it. may / might 表示一种可能性很小的推测。多用在肯定句或否定句中，might 用在疑问句中表示“可能”，语气最弱。 My sister may not be in her room at this moment. The scientists might be discussing the pollution problem. 2. may和might 在表示推测的情态动词中，must 的把握性最大，意为“一定；肯定”。表示对一般情况的推测。 You sister must be a doctor, isn’t she? Li Ping must be punished by his father. 3. must 和can （以上几句要注意反意疑问句的构成）can的推测用法：肯定句中，can 可以表示客观的（理论的）可能性，并不涉及具体某事是否会发生，此用法常常可以说明人或事物的特征。 Accident can happen on such rainy days. can’t do表示对现在发生的事情做否定的推测。can’t have done 表示对过去发生的事情做否定的推测。 He can’t be there now. He can’t have slept through all that noise.英语中，情态动词would 并不一定与过去的时间有关，所表示的可能性比will弱。 A man of good sense would not laugh in such a case.4. would 和should should 表示推测时，表示确定或可能有的未来或期望。 It’s nearly seven o’clock. Jack should be here at any moment. ─When can I come for the photos? I need them tomorrow afternoon. ─They should be ready by 12:00.Let’s end of this part.
