Question

请问宾语从句不定式怎么用？什么意思呢？着急 请详细 非常感谢

Answer 1

不定式是指to 加 动词，一般表示将来，目的，针对等含义。不定式本身不能直接作为从句，不定式要有主语等才能作为句子放到从句中。

置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾语从句的语序必须是陈述语序。

谓语动词、介词、动词不定式、动词现在分词、过去式、过去分词后面都能带宾语从句。

有些形容词（afraid,sure,glad等）之后也可以带宾语从句。

宾语从句有三种：

1、陈述句作宾语从句，由that引导，that可省略；

2、一般疑问句作宾语从句，由if或whether引导，用陈述句的语序；

3、特殊疑问句作宾语，由特殊疑问词引导，用陈述句的语序。

I have something to do.这个意思是我有事要做；这是做宾语补足语
不定式是指to 加 动词，一般表示将来，目的，针对等含义。不定式本身不能直接作为从句，不定式要有主语等才能作为句子放到从句中。
动词不定式短语代替宾语从句时,经常和疑问词连用.
1.I didn't know what I could do. =I didn't know what to do.
2.She hasn't decided where she will go.=She hasn't decided where to go.
3.They want to know when they will leave.=They want to know when to leave.
4.He doesn't know how he can get to the park.=He doesn't know how to get to the park.
5.Jim didn't decide which coat he should buy.=Jim didn't decide which coat to buy.
