题目内容
14.They have a lot of friends at school.(改为一般疑问句)Do theyhave a lot of friends at school?
分析 他们在学校有很多朋友.
他们在学校有很多朋友吗?
解答 答案:Do,have.结合句意这里是一般现在时,have是实意动词有,主语they复数,故借助于助动词do构成一般疑问句,后加动词原形,故答案是Do,have.
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?
