didn’tdoDidfindany

Wasany巧记动词过去时态动词一般过去时，表示过去发生事；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。返回上页进入下页课后练习：看我的一、写出下列单词的过去式walk_______look______talk______play______do______have______shop______want_______二、用单词的适当形式填空1、----Didyou________(have)anicetrip?----Yes,I________(have)agratetrip.2、I________(look)atapictureyesterday.3、We__________(shop)yesterday.walkedlookedtalkedplayeddidhadshoppedwantedhavehadlookedshopped4、Whatdidyou_______(do)?5、I_________(talk)toM
