否定转移和宾语从句的简化

 1. 否定转移
在主从复合句中，当主句的主语为第一人称，谓语动词是think, believe, suppose等时，要将从句的否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。
如：I don't think he will come with you.
我认为他不会和你一起来。
I don't think I could lift it.
我想我提不动它。
I don't believe that he will come.
我认为他不会来。
 2. 宾语从句的简化
(1) 当宾语从句的主语和主句的主语相同，且主句的谓语动词是hope, wish, decide, agree, choose等时，从句可简化为不定式结构。
如：I hope that I can receive your e­mail.
＝I hope to receive your e­mail.
我希望能收到你的电子邮件。
(2) 当宾语从句的主语和主句的主语相同，且主句的谓语动词是know, remember, forget, learn等时，从句可简化为“疑问词＋不定式”结构。
如：She doesn't know what she should do next.
＝She doesn't know what to do next.
她不知道下一步该做什么。
(3) 当主句的谓语动词是ask, tell, show, teach等，且宾语从句的主语和主句的间接宾语一致时，从句可简化为“疑问词＋不定式”结构。
如：Will you please show me how I can work it out?
＝Will you please show me how to work it out?
请你告诉我怎样把它解答出来好吗？
(4) 宾语从句可以简化为名词或名词短语。
如：I don't believe what Tom said.
＝l don't believe Tom's words.
我不相信Tom所说的话。
