二， 宾语从句
1. 由关联词that引导的宾语从句。
由关联词that引导的宾语从句时， that在句中不充当任何成分，在口语或非正式的文体中常被省去，但如果从句是并列句时，第二个分句前的that不可省略。
He said (that) he was innocent and that should be set free immediately.
2. 由who， whom, which, whose, what, when, where, why, how, whoever, whichever等关联词引导的宾语从句，应注意句子的语序要用陈述语序。
I want to know what he said to you yesterday.
3. 在宾语从句中，引导词whether和if 基本一样，但介词后的宾语从句多用whether。
I will see whether/if she is at home.
Everything will depend on whether the negotiation will go on smoothly.

三， that，what引导宾语从句的区别
在宾语从句中， that没有词义，在句中不作任何成分。当从句意义完整，不缺任何成分时，往往选用that；而what引导宾语从句时，意为“什么” ，有时候可以不译，在从句中作主语或宾语。
