[名词性从句]引导名词性从句的连接词
引导名词性从句的连接词可分为三类: 连接词: that, whether ,if (不充当从句的任何成分)
连接代词:what, whatever, who, whoever, whom, whose, which
连接副词:when, where, how, why
不可省略的连词:
1. 介词后的连词
2. 引导主语从句和同位语从句的连词不可省略。例如:
That she was chosen made us very happy. 她被选上了,我们很高兴。
We heard the news that our team had won. 我们听到消息说我们队赢了。
比较:whether与if 均为"是否"的意思。 但在下列情况下,whether 不能被if 取代:
1. whether引导主语从句并在句首
2. 引导表语从句
3. whether从句作介词宾语
4. 从句后有"or not"
大部分连接词引导的主语从句都可以置于句末,用 it充当形式主语。例如:
It is not important who will go. 谁去,这不重要。
It is still unknown which team will win the match. 到底谁赢呢,形势尚不明朗。
[名词性从句]名词性that-从句
1)由从属连词that引导的从句叫做名词性that-从句。That只起连接主句和从句的作用,在从句中不担任任何成分,本身也没有词义。名词性that-从句在句中能充当主语、宾语、表语、同位语和形容词宾语。例如:

宾语:John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。

形容词宾语:I am glad that you are satisfied with your job. 你对工作满意我感到很高兴。

It's a pity that you should have to leave. 你非走不可真是件憾事。
