3、一般疑问句: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, Im not.
Is she a doctor? Yes, she is. / No, she isnt.
Does he work in a hospital? Yes, he does. / No, he doesnt.
Are there four fans in our classroom? Yes, there are. / No, there arent.
Are you going to buy a comic book tonight? Yes, I am. / No, No, I am not. (Yes, we are. / No, we arent.)
Will he eat lunch at 12:00? Yes, I will. / No, I will not(wont).
Are they swimming? Yes, they are. / No, they arent.
Did you watch TV yesterday evening? Yes, I did. / No, I didnt.
☆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。
