人教版（2019）选择性必修 第三册Unit 2 Healthy Lifestyle单元语法和写作（重难点词句语法基础 提升练）学案（含答案）

选择性必修三 Unit 2 Healthy Lifestyle 单元语法及写作
一、单元语法：不定式作主语
【用法归纳】
直接作主语：To say is one thing, and to do is another.
当作主语的不定式结构比较复杂时，往往用it作为形式主语：
It is rude to turn your back to your teacher and refuse to answer.
常用的结构由：It is/was adj. (for/of sb. ) to do sth. (注意：当adj用来修饰sb.的时候，介词用of)
It is/was a/an +n. to do sth.
It takes/took sb. time/courage/patience…to do sth.
It costs/cost sb. money to do …
It requires/required courage/patience/hard work… to do sth.
注意：1). 单个不定式作主语时，谓语动词用单数形式；两个及以上的不定式作主语时，谓语动词用复数形式；但作为一个整体时，谓语动词为单数形式。
Where to go on holiday and when to go for the holiday have not been decided.
Where and when to go on holiday has not been decided.
2). 不定式作主语时，若其后需要动词作表语，那么表语最好也使用不定式来保持形式一致。
To help us out is to help yourself out.
