名词性从句中要注意的几个问题一.名词性从句中主句和从句的主谓一致、语序主语从句做主语相当于单数第三人称作主语，谓语动词用单数，如果由and 连接两个或两个以上的主语从句做主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，谓语动词用单数。
如：When the meeting will begin has not been decided yet.When they will start and where they go have not been decided yet.名词性从句在句中要用陈述句语序。
如：He asked me what was the matter with me.We’ve heard the news that well move into the new house.二.名词demand, suggestion, proposal, advice 等词后的同位语从句的语气要用虚拟语气,结构为should + do, should 可省略1.He gave me a suggestion that I ( should ) be calm now.2.The suggestion that the plan (should) be delayed will be discussed tomorrow.三.whatever/whoever 的功用：Whatever/whoever可引导主语，宾语，表语从句，并在从句中做主语，宾语，表语。
这种用法中，whatever/whoever 不含疑问意义。
Whatever=anything that; whoever=anyone who 1. Whoever breaks the law is to be punished.Anyone who breaks the law is to be punished.2. They will do whatever he wants them to do.They will do anything that he wants them to do.疑问词 + ever和no matter + 疑问词的区别：①疑问词 + ever可引导名词性从句，在主从句中要充当一定的成分。

arrive名词三.whatever/whoever 的功用：名词性从句常见错误例析1.【误】 He will come back surprises all of us.【正】 That he will come back surprises all of us.【析】 that引导名词性从句时,尽管无意义也不充当成分,但除了在动词后引导单个宾语从句时可省略外,其它情况不能省略。
2.【误】 That he really means is what he doesn’t agree with us.【正】 What he really means is that he doesn’t agree with us.【析】 that和what均可引导名词性从句，区别在于：what在名词性从句中作主语、宾语或表语，而that在名词性从句中不作任何成分，只起连接作用。
误句的主语从句应该用what作means的宾语，表语从句中应该用that，that在从句中不作任何成分。
3.【误】 The news which our team had won pleased everyone.【正】 The news that our team had won pleased everyone.【析】 which在此句中不充当成分，说明从句不是定语从句而是同位语从句。
同位语从句不能用which引导，故改为that。
4.【误】 The reason why he failed in the exam was because he was too careless.【正】 The reason why he failed in the exam was that he was too careless.【析】主语为reason时，引导表语从句的关联词一般用that，不用because，构成The reason why/for which/that/for . . . is that . . . 句型。
