2023年初中英语知识总结：一般过去时

一般过去时

(1)一般过去时表示过去某一时间所发生的动作或存在的状态。

① 当动词为 be 动词时，应该用相应的过去式：

am is----was;are----were

否定形式为：was not----wasn’t;were not----weren’t

疑问句是将 was, were 置于主语之前。

I was in Grade Three last term.

I wasn’t in Grade Two last term.

Which grade were you in?

② 当动词为实义动词时，用动词的过去式，过去式的变化有规则和不规则变化。规则变化如下：

动词过去式的不规则变化需要逐个记忆。见初三教材后的不规则动词变化形式表。

go----went;begin----began;sleep----slept;run----ran;

I heard the good news just now.

The twins didn’t go to school last week.

Did you see the film yesterday ?

(2)一般过去时的用法

① 表示过去某一时间或一段时间发生的动作或存在的状态。常和表示过去的状语连用：yesterday, last week, a minute ago, in 1998, just now, in those days 等。例如：

They had a baby last month.

My mother was ill yesterday.

He went out just now.

② 用于 since 引导的从句，主句的谓语动词如果用现在完成时，since 引导的从句一般要用一般过去时。如：

He has worked in the factory since it opened in 1990.

You haven’t changed much since we last met.

注意：

a.)表示过去的时间状语常见的有：yesterday, last night(week, year, month, Sunday), then, at that time, just now, a few days(weeks, months) ago.以及由 after, before, when, while 引导的的表示过去的时间状语。

b.)一般过去时可以用来表示现在的时间， 这主要用于日常会话，使用的语气较为婉转客气。如：

I wanted to ask if I could borrow your bike.
