宾语从句(构成、直接引语和间接引语)
宾语从句是在复合句中充当宾语的句子,常跟在动词或介词的后面。
常见的引导词有:that, if/whether, what, who, whom, whose, which, when, where, why, how 等。
a. 由that引导的宾语从句,that无任何意义,可以省略。
They say (that) he is much better.
I am glad (that) you have come.
b. 由if或whether引导的宾语从句,if或whether表示“是否”。
I want to know if /whether you still work in the factory.
He asks if /whether we will go to visit the museum next week.
c. 由疑问代词和疑问副词引导的宾语从句,疑问代词或疑问副词有意义,并在从句中充当一定的句子成分。
Do you know when we are going to Beijing?
He wants to know who lives in this room.
I wonder what he is doing now.
I am really surprised at why he said so.
d. 直接引语变间接引语时人称和时态的变化。
"I enjoy the film very much." He said.(直接引语)
→He said he enjoyed the film very much.(间接引语)
They told us, "It's important for us to plant more trees.” (直接引语)
→They told us it was important for them to plant more trees.(间接引语)
e. 宾语从句中的时态呼应:
当主句为一般现在时,从句的时态根据具体的情景选用(如:一般现在时、一般将来时、一般过去时等等)。
I want to know whether the answer is right or not.
I hear that you didn’t pass the entrance test.
当主句为一般过去时,从句的时态只能用过去的某种时态(如:一般过去时、过去进行时、过去完成时、过去将来时等等)。
My friend told me that she would go there the next day.
We wondered whom she was waiting for.
主句是过去时,从句时态的变化
一般现在时
→
一般过去时
现在进行时
→
过去进行时
现在完成时
→
过去完成时
一般将来时
→
过去将来时
一般过去时
→
过去完成时/一般过去时
注意:
●当从句为一般过去时,如果从句表达的是客观真理、自然规律,其时态不受主句的影响,
仍然用一般现在时。
The teacher told us that there is no air on the moon.
●宾语从句应该用“从属连词+陈述句语序 ”。
Is everybody here? He wants to know.(合并为一句)
→He wants to know if /whether everybody is here.
Why are you late? Mr. Li asked me.(合并为一句)
→Mr. Li asked me why I was late.
真题讲解
中考英语“根据所给要求,改写下列句子”
Will Bob join the swimming club? Please tell me.(合并句子)
→Please tell me __________ Bob __________ join the swimming club.
正确答案:if/whether; will。本题考点是宾语从句。因为原句子是一般疑问
句,所以宾语从句中的引导词应该是if或whether;同时还应明确宾语从句中的语序是陈述句,故把助动词will放在主语Bob后面。
中考英语选择题
Tim told us that his company ______ robots to do some of the work.
A) uses B) will use C) has used D) would use
正确答案是D。本题考查的是宾语从句的时态。主句为一般过去时,从句要用相应的过去
