1、一般疑问句1. 一般疑问句里有be(am, is, are)动词的:陈述句改为疑问句时,原则是:原句子里有什么动词(如be动词),就把什么动词(be动词)提前,其它照搬下来变为疑问句。在对疑问句做肯定或否定回答时,原则是:用什么提问,就用什么回答。如用be动词提问,就用be动词回答。肯定句、否定句和一般疑问句的互换。(1)如果句中有this/those/these, 在做肯定否定回答时要变为it (单数)或 they(复数).如:肯定句:This is a book. These/Those are banana trees.否定句:This is not a book. These/Thos
2、e are not banana trees.一般疑问句:Is this a book? Are these/those banana trees?肯定回答:Yes, it is. Yes, they are.否定回答:No, it isnt. No, they arent.(2)如果句中有第三人出现时,在变为疑问句时,my 要变为your, I 要变为you. 做肯定否定回答时要用he/she(单数)或 they (复数)。肯定句:This is my new teacher. They are students in No.1 Middle School.否定句:This isnt my
3、teacher. They are not students in No.1 Middle School.一般疑问句:Is this your new teacher? Are they students in No.1 Middle School?肯定回答: yes, he/she is. Yes, they are否定回答: No, he/she isnt. No, they arent. 肯定句:There is a desk in the room. It is a map.否定句:There isnt a desk in the room. It is not a map.一般疑问句
4、:Is there a desk in the room? Is it a map?肯定回答: Yes, there is. Yes, it is.否定回答: No, there isnt. No, it isnt. 2. 句中有情态动词can 时,按照用什么提问就用什么回答原则。肯定句: I can play football.否定句:I cant play football.一般疑问句:Can you play football?肯定回答: Yes, I can. 否定回答: No, I cannt.3. 句中没有be 动词也没有情态动词can时,要用助动词do(复数,第二人称), doe
5、s(第三人称单数)来提问。肯定句: He likes playing football. They like playing football.否定句: He doesnt like playing football. They dont like playing football.一般疑问句:Does he like playing football? Do they like playing football?肯定回答: Yes, he does. Yes, they do.否定回答: No, he doesnt. No, they dont. 1、看句中有无be动词,如有,把be动词提到句首即可。2、看句中有无情态动词,如有,把情态动词提到句首即可。3、如上述二者都没有,就应把助动提到句首。分四个步骤:(1)肯定陈述句中本来是没有助动词的,要加上去,位置在主语(某人或某物)后,动词前。(2)确定助动词用do还是does,根据句中动词,动词是原形的助动词就用do,动词是第三人称单数的助动词就用does(3)把助动词后提到句首。(4)原句中动词假如发生变化就要恢复成原形。强调一点,有some的要考虑是否要用any。Thereissomewaterontheplayground.
