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。
