第01练 一般过去时-2023【暑假分层作业】八年级英语（人教版）

第01练 一般过去时 1.概念： 表示在过去某个时间里所发生的动作或存在的状态。 2.谓语构成 一般过去时的谓语不管主语的人称和单复数都用动词的过去式表示，动词的过去式有规则与不规则两种。规则动词的过去式在动词原形后加-ed, 不规则动词的过去式要逐个记忆。 3.规则动词的过去式变化方式如下： 情 况 变 化 规 则 例 词 一般情况 在动词原形后 加-ed consider→considered pass→passed 以不发音的 e 结尾的词 在动词后加-d achieve→achieved increase→increased 以辅音字母+y结尾的词 变y为 i， 再加-ed cry →cried carry →carried try →tried study →studied 以辅音字母结尾的重读闭音节词 双写该辅音字母，再加-ed plan→planned stop →stopped 4.不规则动词的过去式 （举例） feed → fed go → went see → saw do → did get → got fall →fell leave →left am →was are → were give → gave have → had think → thought 5．一般过去时的否定式和疑问式 1）实义动词的否定式要借助助动词didn’t。 否定句构成： 主语 + did not (didn’t) + 动词原形… 例如：I didn’ t see your sister last Sunday. 我上星期天没看见你的姐姐。 2）实义动词的疑问句构成：Did + 主语 + 动词原形 …? 例如：— Did you notice the weather today？你注意到今天的天气了吗？ --- Yes, I did. / No, I didn’t. 是的，我注意到了。/ 不，我没注意到。 3）be (was, were) 动词的一否定句和疑问句不用助动词did --直接用’ was, were提问（放在主语前面）构成疑问句 --在“be”动词后加not 构成否定句: was not / wasn’t were not / weren’t。 例如： Was he at home last night? Yes, he was. / No, he wasn’t. Were you in Class 1, Grade 3 last year? Yes, I was , / No, I wasn’t. Was your father busy last week? Yes, he was. / No, he wasn’t. When were you born? I was born in 1990. I was not born in 1988. We were not free yesterday. 如何判断一般过去时： 1）表示在确定的过去某个时间里所发生的动作或存在的状态。 常用的时间状语有： yesterday, ;last year(week,month...), three hours ago, the other day (几天前) ，just now （刚才）, in 1998等。例如： I sent e-mail to my best friend yesterday. 我昨天给我最好的朋友发邮件。 They didn’t have a meeting last Tuesday. 他们上个星期二没有开会。 She didn’t go shopping this morning. 她今天上午没有支购物。 Where did you go just now? 你刚才去哪儿了？ 注意：描写已故的人的动作或状态需用动词一般过去时。 2）表示在过去一段时间内，经常性或习惯性的动作。例如： In my childhood, I often played in the street. 童年时，我经常在街上玩耍。。 Lin Ping didn't come here last year 林平去年没来这 Childr
