【#英语资源# 导语】在复合句子中起名词作用的句子叫名词性从句。简单把它理解成名词,但形式是一个句子。那主语从句就是在句中作主语,主语从句的位置与陈述句中主语位置相同的,统观主语从句的考核占有相当比重,下面和©文档大全网具体来看一下主语从句不可位于句首的五种情况吧!
(1) if 引导的主语从句不可居于复合句句首。
It is uncertain if he will leave for Beijing tomorrow.
(2) It is said , (reported) …结构中的主语从句不可提前。例如:
It is said that President Jingo will visit our school next week. (right)
That President Jiang will visit our school next week is said. (wrong)
(3) It happens…, It occurs… 结构中的主语从句不可提前。例如:
It occurred to him that he failed in the examination. (right)
That he failed in the examination occurred to him. (wrong)
(4) It doesn’t matter how/whether …结构中的主语从句不可提前。例如:
It doesn’t matter whether he is wrong or not. (right)
Whether he is wrong or not doesn’t matter. (wrong)
(5) 含主语从句的复合句是疑问句时,主语从句不可提前。例如:
Is it likely that it will rain in the evening? (right)
Is that will rain in the evening likely? (wrong)
注:What 引导主语从句时在句时在从句中充当句子成分,如主语.宾语.表语,而that 则不然。
例如: 1) What you said yesterday is right.
2) That she is still alive is a consolation.
