17、pped。以辅音字母+y结尾的动词变y为i，再加ed。 如：studied，worried。有些动词不符合上面的规则，需要特殊记忆。 如：am(is)-was,are-were,go-went,eat-ate, swim-swam,buy-bought,see-saw, teach-taught,bring-brought,think-thought, fall-fell,hurt-hurt,break-broke,win-won, lose-lost二、一般过去时的基本用法 1. 带有确定的过去时间状语时，要用过去时，如：yesterday（昨天）、two days ago（两天前 ）、la

21、示。实际上，这句话暗指：But now I know you are here.）I thought you were ill. （这句话应是在说话之前，我以为你病了。但是现在我知道你没病）辨别正误 Li Ming studied English this morning.把此句变为一般疑问句1.Did Li Ming studied English this morning？动词应该用_2.
