--- Non Clause 名词性从句的功能
功能相当于名词, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等, 因此根据它在句中不同的语法功能, 名词性从句又可分为四类。即:主语从句、表语从句、宾语从句和同位语从句。
在句中作主语成分在句中作宾语成分在句中作表语成分在句中作同位语成分辨别从句:
1. What we need are good doctors .
2. It is obvious that we need more equipment.
3. The problem is that millions of people
die of illnesses caused by smoking.
4. The question remains whether we can
win the people.

7. Word came that he had been abroad.
8. That question whether we need it has not been considered.
9. The fact that he turned out to be a thief amazed everyone.
10. The fact that we talked about is very important.
11. Although he is young, he knows a lot.辨别从句:
1. What we need are good doctors .
What引导的主语从句,what在从句中做宾语。

辨别从句:
3. The problem is that millions of people die of illnesses caused by smoking.
That引导的表语从句,that在名词性从句中不做任何成分。
4. The question remains whether we can win the people.
Whether引导的表语从句,表语从句表“是否”只能用whether,不用if,不做任何成分。

How引导的宾语从句,how做状语。
7. Word came that he had been abroad.
That引导的同位语从句,that不做任何成分,当同位语从句的先行词做主语为避免头重脚轻将从句放在句末。
8. That question whether we need it has not been considered.
Whether引导的同位语从句,引导同位语从句只能用whether,不用if,不做任何成分,是“是否”的意思。
9. The fact that he turned out to be a thief amazed everyone.
That引导的同位语从句,that不做任何成分。
10. The fact that we talked about is very important.

1.首先找出句子中的主谓结构。
2. 根据从句的位置和引导词的用法来辨别从句。
a. 位于句首,或放在句末,句首用形式主语it,为主语从句。
b. 在行为动词后或介词后,为宾语从句。
c. 在系动词后,为表语从句。
d. 在代词后,从句为定语从句;在名词后为定语从句或同位语从句。
e. 从句表时间、地点、让步、条件、原因、结果等时,为状语从句。名词性从句的连接词:
连词:that(无任何词意)
whether,if(均表示“是否”)
as if, as though(好像;似乎)
2. 连接代词:what, whatever,who, whoever, whom, whose, which, whichever, whomever
3. 连接副词:when,where, how,why
