英语语法中名词性从句如何准确判读

Question

如题所述

Answer 1

名词性从句一般是主语从句，宾语从句，表语从句和同位语从句。顾名思义，一个句子做主语称为主语从句，如(what) he said is not true.
其他依次类推。但要注意，
1.宾语从句可用在及物动词或介词后，有时还可用在形容词后。如。
He asked whether he could visit me.
It depends on whether you can finish your task.
I'm sure that we can finish it on time.
2.同位语从句一般在抽象名词后，和定语从句的位置差不多，注意区别。
He recives a piece of news that they won the match.(同位语从句)
He recives a piece of news that is exciting.(定语从句)
最后表语从句显然是一个句子充当表语，在系动词之后。如；
the news is what we expected.

Answer 2

需要看这个名词性从句所处的位置。如果在句子的开头就是主语从句，如果在动词或介词后面就是宾语从句，如果在系动词后面就是表语从句，如果修饰一个名词，那就是同位语从句了。例如：
I don't know what he said.宾语从句
That's what he said.表语从句
What he said is wrong.主语从句
The news that we have won the game is inspiring.同位语从句

建议你首先了解一下句子结构，句子成分问题，只有搞清楚了主谓宾定状补的区别，你才能真正理解名词性从句的区分。
