情态动词
学习指南 情态动词是一种带有感情色彩的助动词。它一共有十三个： May, might; can, could; shall, should; will, would; 22
must, ought to, need, dare, used to。为了方便大家记忆，我主要从两个方面讲述情态动词用法： 推测性用法；非推测性用法。 一、推测性用法：
表示推测的情态动词一共有九个。不过，不同的情态动词， 其“可能性”的大小有一定的差异，所以须特别留意。
might “可能性”最小（约10%） 表示“可能” may could can should 表示“很可能” ought to would will 表示“一定”： must “可能性”最大（100%） 说明：上述表示推测性用法的情态动词本身没有时间上的差异。 根据动作发生的“时间”，情态动词的“推测性用法”可分为如下六种： 1、表示对“现在或将来事物”的推测： 谓语：情态动词 + do（动词原形） She may be in the classroom. 她可能在课室里。
She might understand you later. 她可能以后会理解你。
23
He must know what she meant. 他一定知道她的意思。 She may come here tomorrow. 她可能明天到这里来。 He will go to America next month. 他很可能下个月去美国。
说明：表示对将来事物推测，不能用“must”。 例如：He must come here tomorrow.（错误） He is to come here tomorrow.（正确） He is bound to come her tomorrow.（正确） He is sure to come here tomorrow.（正确） He is certain to come here tomorrow.（正确） 明天他一定会到这里来。
2.对“过去或已完成事物”的推测：
谓语：情态动词 + have done（过去分词） 特点：前者有特定的过去时间。 后者没有特定的过去时间。
You must have attended the meeting yesterday. 你一定参加了昨天的会议。
You can't have attended the meeting yesterday. 你不可能参加过昨天的会议。 She might have arrived there last week. 她可能上周就到了那里。
She ought to have finished her homework by now. 到现在她应该做完作业了。
He may have lived in Dongguan for a few years. 他可能在东莞住了好几年了。 说明：
当must表示推测含义时，其否定形式只能用can't，
24
绝对不能用mustn't或needn't。这种情况考试中经常出现。 A: He must have told her the news yesterday.
B: No, he can't have told her the news yesterday.（正确） No, he mustn't have told her the news yesterday.（错误） No, he needn't have told her the news yesterday.（错误）
3.对“现在进行事物”的推测：
谓语：情态动词 + be doing（现在分词） She might be watering flowers in the garden. 她可能在花园里给花浇水。
He should be playing cards with his classmates. 他很可能在跟同学打牌。
4.对“过去进行事物”的推测：
谓语：情态动词 + have been doing（现在分词） They may have been playing cards last night. 昨晚他们可能在打牌。
He should have been studying yesterday morning. 昨天早上他很可能在学习。
You must have been travelling in China last month. 上个月你一定在中国旅行。
