Question

.From the teacher's patient explanation,I have learnt what a big responsibility _ is to educate us .
填it 请问为什么,不是强调句式吧/难道是宾语从句,what a big responsibility做表语?
不懂的别说了,

Answer 1

1、I have learnt +由what引导的宾语从句；但这个宾语从句是,由一个“感叹句”来充当的；
2、感叹句的构成是：
（1）What ++名词 +主语+谓语!
（2）How +形容词/副词+主语+谓语!
（3）What +a/an+形容词+单数可数名词+主语+谓语!
=How +形容词+a/an+单数可数名词+主语+谓语!
3、你给的句子应该是：To educate us is a big responsibility.
将其变成感叹句：What a big responsibility to educate us is!为了句式美观,用it代替,即：What a big responsibility it is to educate us!
4、注意：宾语从句由特殊疑问句或一般疑问句充当时,其疑问句语序变为：陈述语序.上面题目中感叹句,已经是陈述语序.
如：特殊疑问句：What is it?
宾语从句：I don't know what it is.
