参加AEIS考试是我们出国留学的一道门槛,所以选择的人也越来越多,但是其中AEIS语法让很多人感到头疼,所以小编希望大家在备考时多多练习、了解考试信息,下面小编就来为大家介绍一下同位语从句和定语从句的区别!
1.同位语从句和定语从句的区别:
that作为关系代词,可以引导定语从句,充当句子成分,在从句中作宾语时可以省略; that引导同位语从句时,起连词的作用,没有实际意义,不充当句子成分,一般不能省略。
试比较下面两个例句:
I had no idea that you were here.(that引导同位语从句,不能省略)Have you got the idea(that)this book gives you of life in ancient Greece?(that引导定语从句,作宾语,可以省略)2.that-从句作主语通常用it作先行词,而将that-从句置于句末。
用it作形式主语的that-从句有以下四种不同的搭配关系:
a. It + be +形容词+ that-从句
It is necessary that… 有必要……
It is important that… 重要的是……
It is obvious that… 很明显……
b. It + be + -ed 分词+ that-从句
It is believed that… 人们相信……
It is known to all that… 从所周知……
It has been decided that… 已决定……
c. It + be +名词+ that-从句
It is common knowledge that… ……是常识It is a surprise that… 令人惊奇的是……It is a fact that… 事实是……
d. It +不及物动词+ that-分句
It appears that… 似乎……
It happens that… 碰巧……
It occurred to me that… 我突然想起……
It is quite clear that the whole project is doomed to failure.
很清楚,整个计划注定要失败。
It's a pity that you should have to leave.
你非走不可真是件憾事。
3.否定转移
(1) 将think, believe, suppose, expect, fancy, imagine等动词后面宾语从句的否定词转移到主句中,即主句的谓语动词用否定式,而从句的谓语动词用肯定式。
I don't think I know you. 我想我并不认识你。
I don' t believe he will come. 我相信他不回来。
注意:若谓语动词为hope,宾语从句中的否定词不能转移。
I hope you weren't ill. 我想你没有生病吧。
(2)将seem, appear 等后的从句的否定转移到前面。
It doesn't seem that they know where to go.
看来他们不知道往哪去。
It doesn't appear that we'll have a sunny day tomorrow.
看来我们明天不会碰上好天气。
