He was a worker two years ago.2）过去一段时间内，经常性或习惯性的动作。e.g. When I was a child,I often played with fire. Li Lei always walked to school last term.3）谈到已故人的情况时多用过去时。e.g. Lu Xun was a great writer.4）有些发生时间不是很清楚的情况，实际是过去发生的，也应用过去 时态。e.g. What did you say? 另外，还可用过去时表示委婉的语气。e.g. Could you lend me your pen? 其结构是主语+动词的过去式。be 动词的过去式为 was, were；行为动词的过去式有 规则变化和不规则变化两种，规则变化有以下几种情况：1）直接在动词原形末尾加-ed. e.g. workworked; askasked; 2） e 结尾的动词只加-d. e.g. arrivearrived; likeliked.3) 以 末尾只有一个辅音字母的重读闭音节,应先双写这个辅音字母,再加-ed. e.g. shopshopped; 4)以辅音字母+y结尾的动词,先把 y 变成 i,再加-ed. e.g. carrycarried; studystudied.有 些动词变过去式是不规则的,e.g. flyflew; breakbroke; teachtaught. 这些需要象生 单词一样记住. 其句式变化分为两种情况 1)含有 be 动词的依然在 be 上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980? 2)含有行为动词的变否定句要在行为动词前加 助动词 didnt.,同时把动词变成原形; 变一般疑问句,在句首加助动词 did,同时把动词变成原形. e.g. I bought a gift for my mum yesterday. I didnt buy a gift for my mum yesterday. Did you buy a gift for your mum yesterday? 其时间状语为 yesterday 或由其构成的短语,e.g. yesterday morning; 由last+时间构成的 短语, e.g. last year; 由时间段+ago构成的短语, e.g. three days ago; 另外,还有 on the morning of Monday, just now 等,以及一些表示过去时态的从句.注意,在宾语从句中主句为过去,一般从 句也为过去. 常见错误如下: 一 把动词变成过去式易出错 例: 1 They stoped (stop) talking just now. 2 They plaied (play) football yesterday. 答案: 1 stopped 2 played 解析:我们可以记住下面的口诀:动词变成过去式,双写规律要牢记;y 前若是辅音字,y 变 i 加-ed;y 前若是元音字,只须直接加-ed. 二忘记把动词变成过去式 例: I fly (fly) kites on the afternoon of Sunday. 答案: flew 解析:我们可以记住下面的口诀:一般过去时态里,过去形式莫忘记. 自主检测: （一 ）选择 1 She lived there before heto China.
