过去式的用法比如：陈述句、疑问句、否定句和肯定句

Question

如题所述

Answer 1

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。
