专题10 宾语从句
第一部分 语法
宾语从句主要考查的是时态及宾语从句的语序,有时也会考查宾语从句的引导词。考查的主要形式是单项填空、完形填空、短文填空和完成句子。阅读理解和书面表达肯定也会考查到宾语从句。因此学生要熟练掌握宾语从句的用法。
考查重点:
1. 引导宾语从句的连词和代词选择;
2. 宾语从句的语序;
3. 宾语从句的时态。
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只有语法作用,没有实在的意义,在口语和非正式文体中可以省略。
He said (that) he wanted to stay at home.
She doesn’t know (that) she is seriously ill.
I am sure (that) he will succeed.
2. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how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和whether在句中的意思是"是否"。
I want to know if (whether) he lives there.
He asked me whether (if) I could help him.
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 is 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。
Does he work hard? I wonder.
→ I wonder if/whether he works hard.
典例
— Do you know ____________?
—At 9:00 tomorrow morning.
A. when the video meeting began
B. when did the video meeting begin
C. when the video meeting will begin
D. when will the video meeting begin
【答案】C
【解析】——句意:你知道视频会议什么时候开始吗?——明天上午九点。考查宾语从句。问句是一个含宾语从句的复合句,宾语从句中从句语序应该为陈述句语序,因此排除B和D;根据答语“At 9 o'clock tomorrow morning.”可知询问的应该是将来的事,用一般将来时,选项A是一般过去时,故选C。
三: 宾语从句主句与从句时态一致的问题。
1. 如果主句是现在的某种时态(包括一般现在时、现在进行时、现在完成时),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 tomorrrow.
I don’t think (that) you are right.
Please tell us where he is.
Can you tell me how I can get to the railway station?
典例
The policeman asked the little boy if ________ his home.
A. he could find
B. could he find
C. he can find
【答案】A
【解析】句意:警察问那个小男孩能否找到他的家。考查宾语从句。he could find他能找到,陈述语序;could he find他能找到,疑问语序;he can find他能找到,陈述语序。分析句子结构可知此处是if引导的宾语从句,宾语从句要用陈述语序,排除B,结合主句中“asked”可知主句用一般过去时,从句要用过去时态
