英语动词的过去式,除了be动词有人称和数的变化(即was、were)之外,一般动词没有人称和数的变化,一律用过去式表示即可。
一、规则变化。
规则动词过去式的构成一般是在原形动词结尾加上-ed,如:
talk——talked
spell——spelled
start——started
2. 如果原形动词结尾有一个不发音的e,这个e称为silent e或者magic e,则只需加-d即可,如:
like——liked
dance——danced
singe——singed
dye——dyed
canoe——canoed
agree——agreed
3. 动词为重读闭音节或重读r音节结尾,末尾只有一个辅音字母(包括r,但x除外)时,先双写这个辅音字母再加-ing,如:
stop——stopped
spur——spurred
rob——robbed
admit——admitted
occur——occurred
但是:mix——mixed、fix——fixed
4. 以辅音字母c结尾的动词,先加上-k,再加上-ed,如:
picnic——picnicked
traffic——trafficked
panic——panicked
二、不规则变化。
不规则变化的过去式,需要单独记忆,例如:
bring——brought
buy——bought
sell——sold
swim——swam
find——found
put——put。
一般过去时表示过去某个特定时间或一段时间发生的动作或状态,也可以用于表示时间或条件的状语从句,表示过去将来,其上级句子用过去将来时。如:
Never did he smoke.
She told me that she wouldn't go with us if it rained the next day.
I didn't know you were here.
She said that the investigation started the next day.
When she was in the city, she often went to the Central Supermarket.
主语为死者,动词要用一般过去时表示。如:
The woman in the picture was my mother.(这里用was,表示母亲已去世)
My grandfather was a party member.
Shakespeare was the author of Hamlet.
Kant was one of the greatest philosophers in the world.
