知识点1:
一、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
二、用法
主语从句是在复合句中充当主语的从句,通常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾。
1. It作形式主语和it引导强调句的比较
①主语从句常用it作形式主语,一般常用句型为:It is+{名词/形容词/过去分词}+主语从句例如:
It is still a question whether shewill come or not.
It is strange that you should like him.
It is still unknown which team will win the match.
另外,还有一些比较多见的结构:
It turned out that……
It has been proved that……
It happened/occurred that……
It is well-known that等等
②而强调句则不同,它的结构是:It+be+被强调部分+that+从句
强调主语:It is the times that produce their heroes.时势造英雄
强调宾语:It is English that Prof.Lin teaches us.
强调状语:It was in shanghai that I saw the film.
判断是否是强调句有一个方法,就是将that以后的“句子的其余部分”拿出来单独看,看有没有缺成分,缺的是什么成分,再把谓语动词后面that前面的那部分,带到你认为缺成分的地方,如果放进去是一句完整的句子了,那就说明是强调句。
2.用it作形式主语的结构
(1) It is +名词+that从句
It is a fact that 事实是……
It is an honor that 非常荣幸
Itis common knowledge that 是常识
(2) it is +形容词+that从句
It is natural that…很自然……
It is strange that…奇怪的是……
(3) it +不及物动词+that从句
It seems that…似乎……
It happened that…碰巧……
(4) it is+过去分词+that从句
It is reported that…据报道……
It has been proved that…已证实……
3.主语从句不可位于句首的五种情况
(1) if引导的主语从句不可居于复合句句首。
(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.
(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.
(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..
(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?
4. What与that在引导主语从句时的区别
What引导主语从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:
What you said yesterday is right.
三、宾语从句用以区分主语从句的几个特征
1、引导词:what which whose when whet herif where
2、语序:宾语从句必须是用陈述语句。(名词性从句都是陈述语序)
如:I think that you must work harder.
宾语从句的引导词、连接词的区别、否定转移等现象。
补充:从句的语序永远是陈述句。
