language Study:
Noun Clauses as the Subject (主语从句)
主语从句在复合句中做全句的主语. 引导主语从句的连接词有that; whether; who; what;
which; when; where; how; why . 引导主语从句的连接词不能省略. 请注意下面的例句:
1. That she was chosen made us very happy. 她的当选使我们很高兴.
2. Who will go there is not very important. 谁将去那儿并不重要.
3. What we need is more time. 我们所需要的是更多的时间.
4. When they will start has not been decided yet. 他们何时动身还没有决定.
5. Where she has gone is not known yet. 她去了哪儿还不知道
6. How he became a scientist is known to all. 大家都知道他是怎样成为一位科学家的.
上述例句中的主语从句都放在句首. 但有时主语从句放在句首, 会使句子显得笨重, 特别是主语从句太长时. 因此我们常用it做形式主语, 而把主语从句放到句子的后面去. 例如:
7. It is a pity that she has made such a mistake. 真遗憾她犯了这样一个错误.
8. It is strange that he didn’t come yesterday. 真奇怪他昨天没有来.
用it 做形式主语的主语从句常用的句型有:
It is possible / important / necessary / clear that… 很可能…… / 重要的是…… / 必要的是…… / 很清楚…… It is a pity that…. 很遗憾……
It is said / reported / well-known / that… 据说…… / 据报道…… / 众所周知……
It seems / appears / happens that… 显然…… / 似乎是…… / 碰巧……
*** 使用It is possible / important / necessary / clear that…句型时, 从句的谓语用虚拟语气. (should + 动词原形), should可以省略. 例如:
It is necessary that we should learn some English grammar. 我们学一点英语语法很有必要.
*** whether引导的主语从句, 常置于句首, 偶尔也能后置. 例如:
It is not yet known weather / if they will go there. 还不知道他们是否会去那儿
*** If不可以放在句首用来引导主语从句, 但偶见放在主句后面引导主语从句
