你昨晚看电视了吗？—Yes,Idid.是的，我看了。

No,Ididn’t.不，我没看。第14页/共40页行为动词的一般过去时变一般疑问句时，有三个要点：一、句首加did，动词还原。二、将句中的第一人称变为第二人称。三、some变any；already

变yet。第15页/共40页巧记动词过去时态

动词一般过去时,表示过去发生的事;be用was或用were,have,has变had;

谓语动词过去式，过去时间坐标志;

一般动词加-ed，若是特殊得硬记。否定句很简单，主语之后didn’t添;

疑问句也不难，did放在主语前;

如果谓语之前有did,谓语动词需还原;

动词若是was,were,否定就把not添。【总结】第16页/共40页WearrivedinShanghailastmonth.Accordingtotheexample,rewritethesentences.Wedidn’tarriveinShanghailastmonth.Didyouarrive
