宾语从句引导词的用法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.
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know、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：
1、介词后的宾语从句一般不用if。如：
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.
特殊疑问词引导的宾语从句
这种情况下的连接词有两大类：一类是代词，如who/whom/whose及其-ever结构，还有一类是副词，如how/why/when/where及其-ever结构。如：
He wanted to know who had broken the window.
The school will punish whoever breaks the rules.
