题目内容
18.Mr.Smith has saved some money to buy a house in the countryside.(改一般疑问句).Has Mr.Smith savedany money to buy a house in the countryside?
分析 史密斯先生已经存了一些钱去乡下买一所房子.
史密斯先生已经存了一些钱去乡下买一所房子吗?
解答 答案:Has,any.原句 has saved 是现在完成时have/has+过去分词,改为一般疑问句将have/has放句首,some是用在肯定句中,改为疑问句用any,故答案是Has,any.
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?
