这些高中英语单选题为什么 正确答案都选A，请写出所选答案的理由
书上写了应该选A正确答案怎么不是B，求原因.急求高手帮助

Answer 1

1 many a 和 many 都表示很多的意思，区别就在于前者跟名词后谓语动词用单数形式
2 exchangeable 可交换的，exchanged 交换过的，根据句意选前者
3 who 指代 前面的 I 所以选 am
4 that 引导主语从句，which不能引导主语从句，所以应该选B
5 同上，选B
6 我们如何能提高产量仍然是一个问题。
根据句意，选B

追问

那后四道都是属于比较常见的名词性主语从句吗

追答

后三道是

追问

谢谢，那名词性从句和定从、宾从都有什么特征，再写点吧

Answer 2

1.A ("many a+名词单数"作主语时,谓动用单三,因此选A.is)
2.A (exchangeable 可交换的)
3.A (定语从句的谓动由先行词决定,先行词为I,故用am)
4.B (主语从句由that引导,which不能引导主从)
5.B (that引导主语从句)
6.B (How引导主语从句.句意:我们如何提高产量仍是一个问题)

追问

()frightened me was a loud crash from the next room.
AThat BWhy CWhat DHow
() is his own decison.A when he is leaving B when he leaves 这几个单选正确选项是哪个，再帮个忙吧

追答

C.What (What引导主语从句,并在主从中作主语;而that引导主从时不能充当句子成分)

A. (when he is leaving 是主语从句作主语,说此话时,他还没离开,故用现在进行时表示将来动作.句意:他何时离开是他自己的决定.)

追问

谢谢，那主语从句一般都是that、what、which、when这些词引导的吗，还有什么特征

追答

是的,that、what、which、when能够引导主语从句,另外,whether,who,where,why,how等也可引导主语从句;要说特征嘛,那就是任何从句中都必须用陈述语序.
