一般过去时的构成及用法
一、定义: 表示在过去的某个时间里所发生的动作或存在的状态。
时间状语有:yesterday, last week, an hour ago, in 1982等。
1)I was at the zoo yesterday. 昨天我在动物园。
2)I went to bed at eleven last night . 昨晚我11:00睡觉。

二、句子结构
1.在表示某个时间里存在的状态的句子,系动词用过式was,were构成。

2.在表示过去某个时间里发生的动作,用动词的过去式构成。
如:I visited my uncle yesterday. 昨天我拜访了我的叔叔。
规则变化:
(1) 在词尾加ed 或d
英语中大部分动词过去式都是规则变化的,即在动词后加上ed;如果结尾字母是不发音的e,则只要加上一个d就行了。例如:work-worked clean-cleaned
(2) 以辅音字母+y结尾的,变y为i加ed
study-studied hurry-hurried carry-carried
(3) 以重读闭音节结尾的,双写最后的辅音字母再加ed
stop-stopped drop-dropped wag-wagged
2.不规则变化的动词过去式
不规则变化是指过去式不能加ed,用另外一个词来表示。这样的不规则过去式也有很多,只有靠一个一个去记忆了。例如:
is/am-was are-were have/has-had shall-should will-would can-could may- might
go-went come-came take-took
sit-sat say-said get-got swim-swam
run-ran write-wrote sing-sang tell-told
