賓語從句的用法
句子結構：
主句 + 連接詞(引導詞) + 賓語從句
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 等動詞之后,賓語從句中謂語的否定常轉移到主句的謂語上。
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?
在接復合賓語的句子中, 為了保持句子平衡, 用it 作形式賓語,將從句放于句尾, 常接復合賓語的動詞有: 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
表語從句的用法
在復合句中用作表語的從句是表語從句, 引導表語從句的關聯詞與引導主語從句的關聯詞大致一樣,表語從句位于連系動詞后,有時用as if引導。其基本結構為:主語 + 系動詞 + that從句。
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等動詞后均可跟表語從句：
my suggestion is that we should go shopping.
it seems that it is going to rain
2. as if, because 也可引導表語從句。
it looks as if it’s going to rain.
it was because i got up late.
3. 在非正式文體中,引導表語從句的that可以省略。如:
the trouble is (that) he is ill
注意:在表語從句中,當reason做主語時, 引導詞只能用that,不能用because,如:他遲到的原因是因為他沒有趕上早班車。 the reason why he was late was that he didn’t catch the early bus.
同位語從句的用法
在句中起同位語的作用.一般放在名詞 fact , news , idea , promise, thought , suggestion,truth , hope , problem, information, belief, doubt, question dream advice, proof decision等之后,用以說明或解釋前面的名詞.
