否定转移
否定转移是指在think ,guess ,suppose ,believe等动词后面的宾语从句中,如果是否定句则要改为肯定句,同时把主句改为否定句.
如：I think（that）he isn’t a teacher .X
→ I don’t think（that）he is a teacher .
I believe（that）he can’t come here on time .X
→ I don’t believe（that）he can come here on time .
七、主从复合句的反意疑问句有以下四种情况：
（1）x09并列复合句疑问部分,助动词应与邻近从句的谓语一致.
如：Mr.Smith had been to Beijing for several times,he should have been in China now,shouldn’t he?
（2）x09带有定语从句或宾语从句的主从复合句,问句部分的动词和主语与陈述部分的主句动词和主语保持一致.
如：①They all think that English is very important,don’t they?(不用isn’t it?)
②He didn’t think that the news was true,did he?(不用wasn’t/ was it?)
（3）x09带有定语从句或宾语从句的主从复合句,若其陈述部分为I(We) think(believe,suppose,consider,expect) + that从句及其否定形
式时,问句部分的动词及主语与that从句内的动词和主语保持一致.
如：① I think that he has done his best,hasn’t he?
② We think that English is very useful,isn’t it?(不用don’t we?)
③ I don’t think that you can do it,can you?(不用do )
④ We don’t believe that the news is true,is it?(不用do we?)
