主语从句的句式分为哪几种?
的有关信息介绍如下:1、由连词that引导的主语从句。
例如:That you will win the medal seems unlikely.
你想获得奖牌看起来是不可能的。
That you are so indifferent bothers me.
你如此冷淡使我很烦恼。
That she survived the accident is a miracle.
她在事故中幸免于难简直是奇迹。
2、用连接代词或连接副词if, whether 引导的主语从句。
例如: Which of them escaped from the prison is still a mystery.
他们哪一个是从监狱里逃跑的,仍然是个谜。
When they will come hasn’t been made pubic.
他们什么时候来还不知道。
Whether she is coming or not doesn’t matter too much.
她来不来都无关紧要。
3、用关系代词引导的主语从句。
例如:What you need is more practice.
你所需要的是更多的训练。
What I want to know is this. 我想知道的就是这事。
Whatever we do is to serve the people.
我们无论做什么都是为人民服务。
4、主语从句可以直接放在主语位置上,也可以用it作形式主语,而将从句放在句末(尤其是当谓语较短时)。
例如:That light travels in straight lines is known to all.
主语从句,即在复杂句中充当主语成分的句子,例如"That he finished writing the composition in such a short time surprised us all",他在很短的时间内写完作文让我们都很惊讶,此复合句主要描述的是某事让我们惊讶,某事就是该复合句的主语,因此“That he finished writing the composition in such a short time”便是该复合句的主语从句。
引导主语从句的连词主要有:
从属连词:that whether
连接代词:who whoever whom whose what whatever which whichever
连接副词:when where how why
小结:
(1)引导主语从句连词有that,whether,who,what,whatever等
(2)连词位于句首不能省略
(3)主语从句大多数情况下视为第三人称单数,但也有例外,如例(9)
注意:当what引导的名词性分句作主语时,主谓一致问题极为复杂。
