Simple past tense (一般过去时)
We use the simple past tense t talk abut things in the past.
一、什么情况下使用一般过去时?
went是g在一般进去时中所用的动词形式, 是g的过去式。
A mnth ag, Millie and Amy went t Sunshine Park. 一个月前,米莉和艾米去了阳光公园。
Last Sunday, they went t the park again. 上个星期天, 她们又去了那儿。
2. We frm the simple past tense by adding ‘-ed ’ t regular verbs.
提示:一般过去时常与表示过去的时间状语连,如:yesterday, last night, a mnth ag, yesterday afternn, last week, ten years ag
二、规则动词过去式的构成方法
提示: 以元音字母+y结尾的动词按第一条规则,即:+ed, 如: stay —stayed
want— talk —like — wrry —try — stp —
写出下列动词的过去式。
三、不规则动词的过去式不是加ed 构成的, 需要我们记住它们。不规则动词的过去式归纳起来有这样几种类型(见下表):

动词一般过去时,表示过去发生的事;be用was或用were, have, has变had;谓语动词过去式,过去时间做标志;一般动词加-ed,若是特殊得硬记。否定句很简单,主语之后didn’t添;疑问句也不难,did放在主语前;如果谓语之前有did,谓语动词需还原;动词若是was, were, 否定就把nt添。
