· 专题18 宾语从句(学生版)
中考考查重点:
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。
宾语从句是中考必考考点之一,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。
考向一: 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.
考向二: 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.
考向三: 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?
2. 如果主句是过去的某种时态(包括一般过去时、过去进行时),那么宾语从句一定要用过去的某种时态(包括一般过去时、过去进行时、过去将来时、过去完成时)。
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.
He asked if you had written to Peter.
He said that he would go back to the US soon.
3. 如果宾语从句表示的是客观事实或真理,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.
He told me that the earth is round.
宾语从句须注意,几点事项应牢记。一是关键引导词,不同句子词相异。
陈述句子用that;一般疑问是否(if,whether)替;
特殊问句更好办,引导还用疑问词。
二是时态常变化,主句不同从句异。
主句若为现在时,从句时态应看意;
主句若为过去时,
