英语一般过去时
英语动词的一般过去时,主要表示：
1．一般过去时表示过去发生的事,动词用过去式：
What did you do yesterday? 你昨天做了什么?
How long did you stay there? 你在那里待了多久?
Did you sleep well last night? 你昨晚睡得好吗?
The baby cried all night. 宝宝哭了一夜.
2．过去式有两类,一类为规则动词,它们的过去式都以现在式加-ed词尾构成,
一般情况下直接加-ed,如work→worked, want→wanted.原词若以字母e结尾,
则只加-d,如: live→lived, free→freed,以“辅音+y”结尾的词,变y为i,
再加-ed,如：cry→cried, marry→married,以重读闭音节结尾,末尾又只有一
个辅音字母者,将该字母双写再加-ed,如：plan→planned, permit→permitted.
另一类为不规则动词,如：do→did, go→went, see→saw, have→had.许多常用
动词都是不规则动词. 我们的网上免费英语不规则动词练习可以帮到你.
