初中英语动词的时态一般过去时思维导图模板大纲
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
一般情况在词尾加-ed
worked
以-e结尾的在词尾加-d
used lived
以辅音字母加y结尾的,变y为i再加-ed
studied carried
重读闭音节末尾只有一个辅音字母的,双写此辅音字母再加-ed
stopped fitted
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 ?
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.
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.
