3） 情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。
4） 情态动词没有非谓语形式，即没有不定式，分词，等形式。
比较can 和be able to
1）can could 表示能力；可能 (过去时用could),只用于现在式和过去式(could)。be able to可以用于各种时态。

2）只用be able to
a. 位于助动词后。
b. 情态动词后。
c. 表示过去某时刻动作时。
d. 用于句首表示条件。
e. 表示成功地做了某事时，只能用was/were able to， 不能用could。

= He managed to flee Europe before the war broke out.
注意：could不表示时态
1）提出委婉的请求，（注意在回答中不可用could）。

2）在否定，疑问句中表示推测或怀疑。

2） 成语： may/might as well，后面接不带to 的不定式，意为"不妨"。
If that is the case, we may as well try.
典型例题

A. must B. may C. can D. will
答案B. 表可能性只能用may. 此句意可从后半句推出。

mustn't 表示"禁止"，

must表示推测

扩展资料：
情态动词（Modal verbs）本身有一定的词义，表示语气的单词。但是不能独立作谓语，只能和动词原形一起构成谓语。情态动词用在行为动词前，表示说话人对这一动作或状态的看法或主观设想。
情态动词虽然数量不多，但用途广泛，主要有下列： can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would)。
用法：
首先它是动词，而且不同于行为动词，行为动词表示的是可以通过行为来表达的动作（如写，读，跑），而情态动词只是表达的一种想法（如能，也许，敢）。
用法是：情态动词+行为动词原形
例句：I can read this sentence in English.
我能用英语读这句话。
