掌握本单元重点语法----宾语从句和表语从句,并能熟练应用宾语从句和表语从句的相关语法解决相应的语法练习
一、宾语从句
宾语从句:在复合句中起宾语的作用,可以放在动词和介词之后。宾语从句应用陈述句语序。
1.由连接词that引导宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但如从句是并列句时,第二个分句前的that不可省。
E.g. He has told me that he will go to Shanghai tomorrow.
E.g. We must never think (that) we are good in everything while others are good in nothing.
我们决不能认为自己什么都好,别人什么都不好。
注意:在demand, order,suggest, decide,insist,desire,request,command等表示要求、命令、建议、决定等意义的动词后,宾语从句常用"(should)+ 动词原形"。例如:
E.g. I insist that she (should) do her work alone. 我坚持要她自己工作。
E.g. The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。
2.用who, whom,which, whose,what,when, where, why,how,whoever, whatever,whichever等关联词引导的宾语从句相当于特殊疑问句,应注意句子语序要用陈述语序。
E.g. I want to know what he has told you. 我想知道他告诉了你什么。
E.g. She always thinks of how she can work well. 她总是在想怎样能把工作做好。
E.g. She will give whoever needs help a warm support. 凡需要帮助的人,她都会给予热情的支持。
3.用whether或if引导的宾语从句,其主语和谓语的顺序也不能颠倒,仍保持陈述句语序。此外,whether与if 在作"是否"的意思讲时在下列情况下一般只能用whether,不用if:
(1)引导主语从句并在句首时;
(2)引导表语从句时;
