宾语从句其实就是把一个从句(一个功能齐全的简单句或复合句)嵌入一个简单句里。例如:
I declare that my work is original. 我宣布我的作品是原创的。
-
主句: I declare that 我宣布了一件事。
-
从句:My work is original 我的作品是原创的。
-
从句修饰主句:我宣布我的作品是原创的。
例句就是把一个主系表结构的从句嵌入主谓宾结构的简单句里。
可以充当宾语的从句类型
陈述句
一般疑问句(从句中必须是陈述句语序,非疑问句)
-
I wonder whether/if Jim is at home.
-
I wonder whether tomorrow is a good time to visit her.
特殊疑问句(从句中必须是陈述句语序,非疑问句)
-
He didn't tell me when we shall meet again.
-
She always thinks of how she improve her work.
-
She will give whoever needs help a warm support.
-
Can you tell me who the beauty is?
有些动词可直接连接宾语从句,如 believe,admit,consider,dream,promise, declare 等, 基本所有及物动词都能这么用
-
I declare that my work is original.
-
I do not admit that I have cheated.
-
They informed me that I have been promoted.
-
I promise you that I will finish this work within a month.
-
I promise that I will never break my words.
用it做形式宾语, find, feel, consider, make, believe, think等后面有宾语补足语的时候
-
I think it necessary that we take measures to reduced green house emission.
-
I have make it clear that you are not welcomed here.
-
We take it that you will agree with us.
介宾从句
Whether you can succeed depends on how hard you try.
He was not conscious of what a big mistake he had made.
I am surprised at what you said.
介词宾语一般不跟that,只有在固定搭配时例外,如in that,except that, but that, save that等
-
He is different from others in that he is brave.
-
I know nothing about him except that he killed the dragon.
-
Your outlook is perfect except that your shoes are dirty.
形宾从句
形容词有动词的意思, sure, certain, glad, please, happy, sorry, afraid, satisfied, surprised
-
I am sorry I am late
-
I am not sure this is your true intention.
-
We are glad you are one of us now.
用whether或if引导的宾语从句
-
Whether this is true or not, I really don't know.
-
Whether you like me or not, I really don't care.
不能省略引导词that的状况
从句是直接宾语
-
She told me that the match has been concealed.
-
I can't let him know that his mother is ill
多个that引导的从句,后面的that不可省略
-
Mama said (that) you are an angel and that she will not allow anyone to hurt you.
-
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness. 我们认为这些真理是不言而喻的:人人生而平等,造物者赋予他们若干不可剥夺的权利,其中包括生命权、自由权和追求幸福的权利。——经典例句,来自独立宣言。
谓语和that之间有插入语
-
I noticed, for the first time, that she was not the girl I want.
it 做形式宾语时
-
I think it necessary that we hold a meeting to solve this problem.
That前置的强调句
-
That he is stupid is known to everyone.
否定转移
主句的谓语动词是think,believe,imagine,suppose,consider,expect,fancy,guess时,从句的否定词转到主句
-
I don't think (that) you are right.
-
I don't know (that) you are coming. otherwise I would have picked you up at this airport.
主从句时态关系
主句为一般现在时或一般将来时,从句时态不受主句影响
主句为过去时
-
表示同时主从句动作同时发生:从句用一般过去时,过去进行时 She said she was playing video games.
-
动作发生在主句动作之前:从句用过去完成时 He didn't know what they had come here for.
-
动作发生在主句动作之后:过去将来时 He told me he would spend his holidays with his girl friend.
如果从句是客观真理,它不受主句时态的影响
I knew that the earth goes around the sun.
