情态动词考点例析情态动词是体现特定情感态度的助动词，后接动词原形，是动词“大家族”中的重要成员。

让我们一起走进情态动词“园地”吧！★情态动词一表通注意：(1) “May I…?”的否定回答多用mustn‟t。

例如：—May I go?—No, you mustn‟t.(2) 回答must引出的问句时，肯定回答用must，否定回答用needn‟t或don‟t have to。

例如：—Must I leave right now?—No, you needn‟t.(3) need也可作行为动词，有人称、数和时态的变化。

例如：He needs to make a plan.★情态动词考点秀一、考查情态动词表示推测的用法表示推测的情态动词通常有must, can, may, could, might。

must表示说话人对事物把握性较大的推测，意为“一定；准是”，只能用于肯定句；can多用于否定句，表示有把握的否定推测，用于疑问句中可表示询问性的推测；may, could, might表示可能性较小的推测，意为“或许；有可能”，用于陈述句和疑问句中皆可。

may not, could not, might not表示不太有把握的否定推测，意为“可能不会”。
