Question

如何区分表语从句与宾语从句。

Answer 1

宾语从句修饰的是动词
I know that his car is blue.我知道他的车是蓝色的。
能够接宾语从句的动词有say, understang, beleve,think,know,hope,forget,mean,tell,hear,feel,guess 等。
表语从句是跟在be 动词后面
That's where the battle took place.这就是那次战役发生的地方。
That's what I want to be.这就是我的志愿。
由此可知，动词后面的从句是宾语从句，be动词后面的从句是表语从句。
