宾语从句
一.宾语从句的种类
宾语从句是一种名词性从句,在句中作及物动词的宾语,或介词的宾语,或形容词的宾语。根据引导宾语从句的不同连词,宾语从句可分为三类。
1. 由that引导的宾语从句: that 引导的宾语从句通常放在主句谓语动词(及物动词)、介词或形容词之后,引导宾语从句的连词that通常可以省略。
①作及物动词,如:say,think,know,hear,see,hope,wish,remember,forget等的宾语。如: She says (that )she will help me learn English this evening.
②作介词的宾语:连词that引导的名词性从句很少作介词的宾语,一般只用在except,but,in之后,其他介词的宾语从句如果由连词that引导,则需用it作形式宾语。如:
He is a good boy except that he is careless.
You may depend on it that I shall always help you.
③作"be + 形容词"结构的宾语。如:sure,glad,certain,pleased,sorry,happy,afraid等,如:I’m happy (that) I passed the exam.
④如果宾语从句后还有宾语补足语,则用it作形式宾语,而将宾语从句后置。
We thought it strange that Xiao Zhang did not come yesterday.
引导词that不能省略的几种情况:
①and连接的两个表示陈述意义的宾语从句并列时,有时省去第一个从句的连词that,但第二个从句的连词that一般不可以省略。
He told me (that) they could not decide what to do and that they asked my advice.
②that引导的宾语从句作介词宾语时
I know nothing about him except that he is from the south.
③that从句位于句首时
That she is a good girl I know.
④宾语从句的主语是this/that或有this/that修饰时
I think that this part is very important.
⑤宾语从句由it作形式宾语代替时
We all consider it important that children should take plenty of milk.
2. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how等引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。
Do you know who (whom) they are waiting for?
He asked whose handwriting was the best.
Can you tell me where the No.3 bus stop is?
I don’t know why the train is late.
3. 由if或whether引导的宾语从句,if/whether意为"是否”。常用在ask,wonder,doubt,find out,be uncertain /doubtful /等后,二者通常可以互换。
I want to know if (whether) he lives there.
If和whether的区别
①介词后的宾语从句一般用whether
The teacher worried about whether she had hurt the girl’s feeling.
②与 or 连用分别引导两个从句时,特别是句中有or not时用whether
I wonder whether or not we should take part in this activity.
I don’t know whether he is wrong or she is wrong.
③宾语从句位于句首时,一般用whether
Whether he will join in the winter camp,I don’t care.
④在动词不定式之前只能用whether。
He doesn’t know whether to go or not.
⑤在容易产生歧义的句子,一般用whether。
Let me know whether you can come. 告诉我你是否能来。
二、宾语从句的语序
宾语从句的语序应为陈述句的语序,即按照主语、谓语的顺序。
1. 陈述句变为宾语从句,语序不变,即仍用陈述语序。
He was an honest boy. The teacher said. → The teacher said(that) he was an honest boy.
2. 一般疑问句和特殊疑问句变为宾语从句,语序变为陈述语序。
①带有系动词be(is,am,are,was,were)的特殊疑问句。
Do you know how old he is.
②带有情态动词can/should等的特殊疑问句
→ Can you tell me what I should do? ③带有助动词do/does/did的特殊疑问句。
→ Do you know where I put my wedding ring? → Do you know what Sue thinks about Lulu?
注意:当疑问代词what、who在特殊疑问句中作主语时,该特殊疑问句本身就是陈述句语序,所以当该句用来作宾语时,语序不需要调整。
What’s wrong with you? 怎么了? → He asked the girl what was wrong with her.
What has happened to him? → We want to know what has happened to him.
四、宾语从句主句与从句时态一致的问题。
1. 如果主句是现在时,那么宾语从句的时态可根据实际情况而定。
I remember he gave me a book yesterday.
He has told me that he’ll leave for New York tomorrow.
I don’t think (that) you are right.
Please tell us where he is.
2. 如果主句是过去的某种时态,那么宾语从句一定要用过去的某种时态。
He told me that he would take part in the high jump.
He asked what time it was.
He told me that he was preparing for the sports meet.
3. 如果宾语从句表示的是客观事实或真理、自然现象、名言警句、格言等,此时宾语从句用一般现在时即使主句是过去时,从句也用一般现在时态。
Our teacher said that January is the first month of the year.
Scientists have proved that the earth turns around the sun.
五、判断技巧
1、判断是否为宾语从句:空格部分位于谓语动词或者介词后面,空格后跟着完整的句子或者缺少某个成分的句子。
2、根据空格后的内容选择引导词:空格后句子完整,主句表达的意思是明确的,一般选择that, 主句表达的意思是不明确的,一般选择if/whether。空格后句子不完整,根据句子意思选择连接代词和连接副词。
