题目内容
5．I have a ping-ping bat．（变为一般疑问句）Do youhave a ping-pong bat？分析 我有一个乒乓球拍．
你有一个乒乓球拍吗？
解答 答案：Do，have．原句是含有实意动词have的一般现在时，主语you，故借助于助动词do构成一般疑问句，后加原形have，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？
