题目内容
16.That is my pencil case.(改为一般问句)Isthatyour pencil case?分析 那是我的铅笔盒.
那是你的铅笔盒吗?
解答 答案:Is that.原句是含有be动词的肯定句,将be动词提前构成一般疑问句,故答案是Is that.
点评 一、含有be动词(am/is/are/was/were)动词的一般疑问句,通常把be动词调到句首.
二、含有情态动词(can/may/must/could)的一般疑问句,把情态动词调到句首.
三、句子里没有be动词、助动词、情态动词等,就需要加助动词do,does,、did(过去式)来构成疑问句,加上这些助动词后,句子中谓语动词必须用原形.
其句型为:Do/Does/did+主语+动词原形+其它?
