　　重点句型
　　1. 英语句型中的否定转移
　　在英语中，如果主句的动词是think, suppose, expect, believe, imagine 之类的动词，其否定形式应转移到主句。构成反意疑问句时，主语是第一人称，以从句为准；主语是其它人称，以主句为准。 i don＂t think you＂re right, are you? 我认为你不对，不是吗？
　　mary doesn’t expect she can have a long holiday, does she?
　　练习：a. i don＂t suppose i shall be back until 9 o＂clock, ________________?
　　b. they all think that english is very important, _______________?
　　c. i don’t believe he can afford to buy an apartment, _____________?
　　d. he didn’t think that the news was true, ________________?
　　e._________________________________________我认为你的答案是不对的，不是吗？
　　反义疑问句的回答是根据实际情况来回答的。肯定回答：yes, i do.否定回答：no, i don＂t. 注意: 要前后保持一致，切不可说成＂yes, i don＂t.＂或＂no, i do.

　　having realised是现在分词的完成式，在句中作状语，表示该动作发生在谓语动词的动作之前，相当于when i had realised that… 一般式v.-ing 表示该动作与句子谓语的动作同时发生或在其后发生。其否定形式是在v-ing前加not。
