Unit 7 Abilities 语法专题七情态动词和感叹句一核心语法内容梳理1 情态动词can, could的用法1）can 的用法Can表示某人具有某种能力，意思为“能，会”，也表示客观的可能性，是“能够，可能”的意思，后接动词原形，适用于所有人称。

2）could为can的过去式，表示“能，可以”，另外could可用来代替can,表示更为客气委婉的语气，用来提出要求。

2 感叹句的用法感叹句用来表示强烈的感情，能表达喜悦、愤怒、悲哀、惊奇、厌恶和赞赏等。

在口语中常用省略句，后面的主语和谓语往往省略，有时只用一个词或词组表达。

如：How blue the sky is! 天空多么蓝啊！3）疑问句形式的感叹句：有些感叹句采用一般疑问句形式表示，以否定词开头，在口语中读降调。
