一般过去时的谓语动词要用动词的过去式。动词过去式的构成分规则变化和不规则变化两种形式，不规则变化通常需要逐个记忆，规则变化则遵循以下原则：
(1) 一般在动词后加-ed.如：play—played,offer—offered,weigh—weighed,destroy— destroyed,sign—signed.
(2) 在以字母e结尾的动词后,只加-d.如：like—liked,provide—provided,hate — hated,date—dated.
(3) 在以“辅音字母+y”结尾的动词后,则改y为i,再加—ed.如：supply—supplied,fly—flied,study— studied.
(4) 在以单短元音的重读闭音节结尾且,末尾只有一个辅音字母的动词后,双写最后一个辅音字母,再加-ed.如：plan—planned,refer—referred,regret—regretted,ban—banned.

1.表示在过去某个时间所发生的动作或所处的状态（与现在无关）。常与yesterday,last week,in 1989,just now,a moment ago,the other day等过去具体时间状语连用。
2.在过去一段时间内的经常性或习惯性动作。
注：表示过去经常发生的动作还可用used to和would。

4.一般过去时有时可以表示现在，多与want,hope,wonder,think,intend等动词连用，使语气更委婉。

He opened the door,rushed out and then disappeared.
他打开门，冲了出去，然后就消失了。
2.注意在语境中理解“我刚才/原来还不……”。
Your phone number again?I didn’t quite catch it.
