而宾语从句中的that和which不能互换,that引导的陈述句作宾语,且that在宾语从句中不作任何成份,which的话引导的则是特殊疑问句作宾语(当然语序要调整为陈述句),由于其引导特殊疑问句,所以它在宾语从句是也是作主语或宾语,但其意思是固定为“哪一个”。
The news that/which you heard is not true. 定语从句
I don't know which one I should believe. 宾语从句
I don't know that he was lying. 宾语从句
4.
区别3 : What, Whether(or not), if 可以引导宾从,但不可引导定从
