题目内容
2．She often read some novels when she was free in the middle school．（改为一般疑问句）Did she oftenreadany novels when she was free in the middle school？
分析 她中学的时候空闲时总是看一些小说．
她中学的时候空闲时总是看一些小说吗？
解答 答案：Did，read．结合when she was free in the middle school可知这里read是一般过去式，故借助于did构成一般疑问句，后加原形read，故答案是Did，read．
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？
