5、能综合运用宾语从句。
教学重、难点:
1、掌握引导宾语从句的引导词that、who、what、how、where、when and whether
2、掌握宾语从句的语序:主句+引导词+主语+谓语
3、掌握宾语从句主句与从句在时态上的呼应

The Object Clause (宾语从句)
宾语从句一般由“引导词+主语+谓语+其它”构成,其语序是陈述句语序。
A) Introduced by that
e.g. He says that he wants to speak to the headmaster.
I’m sorry (that) he isn’t here right now.
Note:
1. that 的省略:that 引导的宾语从句用来陈述事实,that本身无词义,在从句中不作任何成分,在口语中或非正式文体中常常可被省略。
e.g. I guess (that) somebody else has borrowed it.
I’m afraid (that) you’ll have to wait.
2. 宾语从句的否定转移:
主句是I/We think/suppose/guess/believe等时,从句中的否定习惯上要转移到 主句中。如:我认为鸡不会游泳。
误:I think chickens can not swim. 正:I don’t think chickens can swim.
此外,上述情况在变成反意疑问句时,附加疑问句要看从句,如果主句的主语不是第一人称,则附加疑问句要看主句。试比较:
I think he is wrong, isn’t he? He thinks he is right, doesn’t he?
B) Introduced by if/whether
e.g. She asked me if/whether I could help her with her English.
I don’t know if/whether it is going to rain.
C) Introduced by relative pronouns and adverbs(连接代词和连接副词)
一、构成:
1. 宾语从句可由连接代词what, who, whom, which等引导,它们在宾语从句中可作主语、宾语、表语和定语等,因此不能省略。
Do you know who will come this afternoon? (作主语)
