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/Those 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 isn’t. No, they aren’t.
(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 isn’t my 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 isn’t. No, they aren’t.
肯定句:There is a desk in the room. It is a map.
否定句:There isn’t a desk in the room. It is not a map.
一般疑问句: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 isn’t. No, it isn’t.
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 can’t play football.
一般疑问句:Can you play football?
肯定回答: Yes, I can.
否定回答: No, I cann’t.
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), does(第三人称单数)来提问。
肯定句: He likes playing football. They like playing football.
否定句: He doesn’t like playing football. They don’t 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 doesn’t. No, they don’t.
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。
There is some water on the playground. →Is there any water on the playground
