初中英语知识归纳总结第三十三课时 动词的时态（二）教学重点一般过去时 一般过去时（1）一般过去时表示过去某一时间所发生的动作或存在的状态。 当动词为be动词时，应该用相应的过去式：am is - wasare - were否定形式为：was not - wasnt were not - werent疑问句是将was, were 置于主语之前。I was in Grade Three last term.I wasnt in Grade Two last term.Which grade were you in? 当动词为实义动词时，用动词的过去式，过去式的变化有规则和不规则变化。规则变化如下：变化规则例词一般情况在词尾加-edworked 以-e结尾的在词尾加-dused lived 以辅音字母加y结尾的，变y为i再加-edstudied carried 重读闭音节末尾只有一个辅音字母的，双写此辅音字母再加-edstopped fitted 动词过去式的不规则变化需要逐个记忆。见初三教材后的不规则动词变化形式表。go - wentbegin - begansleep - sleptrun - ranI heard the good news just now.The twins didnt go to school last weekDid you see the film yesterday ?（2）一般过去时的用法 表示过去某一时间或一段时间发生的动作或存在的状态。常和表示过去的状语连用：yesterday, last week, a minute ago, in 1998, just now, in those days等。例如：They had a baby last month.My mother was ill yesterday.He went out just now. 用于since引导的从句，主句的谓语动词如果用现在完成时，since引导的从句一般要用一般过去时。如：He has worked in the factory since it opened in 1990.You havent changed much since we last met.注意：a. 表示过去的时间状语常见的有：yesterday, last night(week, year, month, Sunday), then, at that time, just now, a few days(weeks, months) ago.以及由after, before, when, while引导的的表示过去的时间状语。b. 一般过去时可以用来表示现在的时间， 这主要用于日常会话，使用的语气较为婉转客气。如：I wanted to ask if I could borrow your bike.
