一、肯定句改否定句

1、be 动词后加not ,诸如:is not(isn't) ,are not(aren't),was not(wasn't) ,were not(weren't) ,am not(无缩写)。

◆ You should go home. 你应该回家。--- You shouldn't go home. 你不应该回家。

3、若无法找到be 动词或情态动词,就在已有动词前额外加助动词否定形式:don't/doesn't/didn't ,同时将动词变原形。

◆ She likes the room. 她喜欢这房间。--- She doesn't like the room. 她不喜欢这房间。

◆ We did our homework yesterday. 我们昨天做了作业。--- We didn't do our homework yesterday. 我们昨天没有做作业。

◆ I studied hard. 我学习认真。Did you study hard? 你学习认

真吗?

三、肯定句改特殊疑问句(四步法 )

#1:在一般疑问句基础上,句首添加一个疑问词即可,但应根据划线部分选用适配的疑问词。

#2:把be 动词或情态动词等放在疑问词后面,若句中没有上述动词,就用助动词替代( do/does/did )。注:Whose(谁的)和

How many(多少)两词除外,须紧跟物品,再写be 动词或情态动词等。

#3:划线部分去掉后剩下的内容照写。注:some 须改成any,I 或we 均改成you,my 或our 均改成your。

一般疑问句,否定句重要知识点

英语重要知识点 陈述句变成一般疑问句:如果句中有必动词be-v(is am are)要将is、am、are提前(如果有助动词要将助动词“抛弃”,将必动词最提前,不管是助动词还是特殊疑问词,必动词在一般疑问句里就是“老大”[1];当变一个句子时,如果句子里有be-v动词的话,往往不能在变一般疑问句时加do或does;如果助动词已经使用了第三人称单数形式,那么句子中的动词不得再次使用第三人称单数形式,要变为动词原形[2]). [1]例:Tom is a student. Does is Tom a student.(×)

Is Tom a student?(√) [2]例:Does he lives in Huang gang(黄冈,中国一城市).(×) Does he live in Huang gang.(√) 用助动词do或does提问(do用于第一人称和第二人称单、复数和第三人称复数;does用于第三人称单数的he、she、it等);如果在第一人称的情况下,往往要将第一人称变为第二人称;在变一般疑问句时,要将动词变化为动词原形;如果陈述句里面有many/some,改一般疑问句或者特殊疑问句时,要将many/some改为any.

一般疑问句系动词be 1.It is a pen. Is it a pen? 2.He is a teacher. Is he a teacher? 一般疑问句系动词be 3.We are students. Are you students?

4.They are doctors. Are they doctors? 一般疑问句助动词 l(我)you(你)they(他们)用do 进行提问 第三人称单数用does进行提问 注:do为does的动词原形,当一个句子重复出现does,要将重复出现的does变为do.
