宾语从句的用法大全
一、定义
宾语从句是名词性从句的一种。在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。
因此，有人把宾语从句分为动词后的宾语从句、介词后的宾语从句和形容词后的宾语从句。如：
∙动词后：I don't know when he came back.linux中国
∙介词后：I'm thinking about who is the right person for the position.
∙形容词后：He's sure she will win the game.

砷中毒（一）that引导的宾语从句
that引导宾语从句时，就是起着连接作用，不在从句中作成分。如：
∙I think that it's very interesting to experience a different culture.
∙He didn't know that he had been to the lecture last night.
此时的that经常被省略，所以上面两句可以改为：
∙I think it's very interesting to experience a different culture.
∙He didn't know he had been to the lecture last night.
需要注意的是，也有that不可省略的情况，常见的有：
1、that作learn、suggest、explain、agree、wonder、prove、mean、state、feel、hold等动词的宾语时。如：
∙She explains that Jack did do the job by himlf yesterday.
2、一个动词带有两个或两个以上宾语从句时，第一个that可以省略，第二个that不可以省略。如：
∙She thinks (that) we did a good job and that things will get better soon.
3、宾语从句中的主语是指示代词this/that/tho/the做主语的定语时。如：
∙We're glad that this book helps you a lot in your rearch.
4、宾语从句是双宾（直接引语和间接引语）中的直接宾语时。如：
∙He told me that he really liked my lessons.
5、当宾语从句前置时。如：
∙That he is sure to help, I believe.
6、当it作形式宾语时。如：
∙She made it clear that he was the one who was in charge of the company.

（二）if/whether引导的宾语从句
当宾语从句要表达“是否”的含义时，连接词语就用if/whether，其主句的谓语动词往往是kn
ow、ask、care、wonder、find out等词。如：
∙He didn't know if/whether she would attend the meeting tomorrow.
注意以下情况一般都用whether，不用if：

∙汉译日She's very curious about whether he is a teacher.
2、在具有选择意义，又有or或or not时，尤其是直接与or not连用时，往往用whether（if…or not也可以使用）。如：
∙I don't know whether/if he comes from England or not.
