情态动词

情态动词是一种本身有一定的词义，表示说话人的情绪，态度或语气的动词，

但不能单独作谓语，只能和其他动词原形构成谓语。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) 。情态动词有几个特点：1、没有第三人称单

数形式，没有ing形式，没有被动形式；2、后面的动词用原型。

常见的情态动词对应的过去式有：

一般现在时过去时一般现在时过去时can could shall should

may might will would

注意，could有时候可用于一般现在时，表示婉转语气。如：Could you tell me the

way to the bus-stop?
