有形式宾语it的几个固定用法

Question

如题所述

Answer 1

固定用法如下：

1. 动词+it+宾语补足语+不定式。当不定式、动名词、从句等复杂成分用作宾语且后面跟有宾语补足语时，通常会在宾语补足语前使用it作形式宾语，而将真正的宾语移至句末。

2. 动词+it+that从句。

3. 动词+it+when/if从句。

4. 动词+prep.+it+that从句。

5. 动词+it+介词短语+that从句。

6. It+be+被强调部分+that/who+其他部分。这是强调句的基本结构。

例句：

1、It was a computer that he bought last week.

2、I took it for granted that he would help us.

3、We really appreciate it when she offered to help.

4、I find it difficult to do the job well.

5、I think it best that you should stay there.
