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。

1）以what开头的感叹句，what作定语，修饰名词（名词前也可以有其他定语），可数名词单数形式前要加不定冠词a/an.

What a clever boy (he is)! 多么聪明的孩子！

2）以how开头的感叹句，how作状语，修饰形容词，副词或动词。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。如：

Isn’t it a lovely view? 多美的景色啊！
