在复合句中作主句的宾语，引导词有：连词：that (that 常可省略),whether, if；代词：who, whose, what ,which；副词：when ,where, how, why等。  that引导的宾语从句(在非正式场合that可以省略) 可跟that从句做宾语的动词有： say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。 例句：The boy believes that he will travel through space to other planets. 注意事项：当主句谓语动词是 think, believe, suppose, expect 等词，而宾语从句的意思是否定时，常把否定转移至主句表示。 例句：I don’t think it is right for him to treat you like that. 由whether,if 引导的宾语从句 由whether(if)引导的宾语从句，实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。一般说来，在宾语从句中whether与if可以互换使用，但在特殊情况下if与whether是不能互换的。 例句：I wonder whether(if) they will come to our party. 只能用whether，不能用if引导的宾语从句 1、在带to的不定式前 例句：We decided whether to walk there. 2、在介词的后面 例句：I’m thinking of whether we should go to see the film. 3、在动词后面的宾语从句时 例句：We discussed whether we had a sports meeting next week 4、直接与or not连用时 例句：I can’t say whether or not thet can come on time.
