小学英语一般疑问句

一般疑问句

表示疑问，一般回答只有两种可能Yes，……或No，……句中没有疑问词。

如何将一个肯定的陈述句改为否定句：

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、does还是did，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，动词用过去式的助动词就有did。

（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。

是指询问事实的句子,此类句子必须用"yes",或"no"来回答.

如:Are you a student Yes, I am / No, I'm not.
Is she a doctor Yes, she is. / No, she isn't.
Does he work in a hospital Yes, he does. / No, he doesn't.
Are there four fans in our classroom Yes, there are. / No, there aren't.
Are you going to buy a comic book tonight Yes, I am. / No, I am not. (Yes, we are. / No, we aren't.)
Will he eat lunch at 12:00 Yes, I will. / No, I will not(won't).
Are they swimming Yes, they are. / No, they aren't.
Did you watch TV yesterday evening Yes, I did. / No, I didn't.

Is she a doctor Yes, she is. / No, she isn't.

Does he work in a hospital Yes, he does. / No, he doesn't.

Are there four fans in our classroom Yes, there are. / No, there aren't.

Are you going to buy a comic book tonight Yes, I am. / No, I am not. (Yes, we are. / No, we aren't.)

Will he eat lunch at 12:00 Yes, I will. / No, I will not(won't).

Are they swimming Yes, they are. / No, they aren't.

Did you watch TV yesterday evening Yes, I did. / No, I didn't.

☆注意☆ 小结:一般疑问句是在肯定句的基础上,

①把动词be调到首位,其他照写,末尾标点符号变成问号即可.

②没有动词be的句子则要在句首加上一个助动词(do,does,did)再把紧跟在后面的动词变回原形,末尾标点符号变成问号即可.

这三个助动词也要根据人称和时态来选择,其中"does"只用于一般现在时主语是第三人称单数的情况,而"did"只用于一般过去时,不论主语是什么人称和数,都用"did" .一般疑问句有个重要的原则就是问和答要一致,即问句里的第一个单词(助动词)和简略答句里的这个词是一致的.
