宾语从句的用法
句子结构:
主句 + 连接词(引导词) + 宾语从句
1.we believe (that) he is honest.
2.do you know what he said just now?
3.i don’t remember when we arrived
4.lily wanted to know if /whether her grandma liked the handbag .
5.we should think of how we can do more for others
在think, believe, suppose, expect 等动词之后,宾语从句中谓语的否定常转移到主句的谓语上。
i don’t believe he will go.
we don’t expect he is coming.
i don’t think he can do it, can he?
you /they don’t think he can do it ,do they?
在接复合宾语的句子中, 为了保持句子平衡, 用it 作形式宾语,将从句放于句尾, 常接复合宾语的动词有: make, find, see, hear, feel, think...
i think it necessary that we take plenty of hot water every day.
i think it a pity to waste the food
表语从句的用法
在复合句中用作表语的从句是表语从句, 引导表语从句的关联词与引导主语从句的关联词大致一样,表语从句位于连系动词后,有时用as if引导。其基本结构为:主语 + 系动词 + that从句。
that’s what we should do.
that’s why i want to see you.
the reason for my absence was that i was ill.
1. be, seem, look等动词后均可跟表语从句:
my suggestion is that we should go shopping.
it seems that it is going to rain
2. as if, because 也可引导表语从句。
it looks as if it’s going to rain.
it was because i got up late.
3. 在非正式文体中,引导表语从句的that可以省略。如:
the trouble is (that) he is ill
注意:在表语从句中,当reason做主语时, 引导词只能用that,不能用because,如:他迟到的原因是因为他没有赶上早班车。 the reason why he was late was that he didn’t catch the early bus.
同位语从句的用法
在句中起同位语的作用.一般放在名词 fact , news , idea , promise, thought , suggestion,truth , hope , problem, information, belief, doubt, question dream advice, proof decision等之后,用以说明或解释前面的名词.
