——动词(一般过去时)
Lesson 8
一般过去时
一般过去时表示过去某个时间发生的事,存在的状态或过去反复发生的动作.
每个动词都有与它相对应的动词过去式.下面我们就来看看动词过去式的构词法.
动词过去式的构词法:
1.大多数动词的过去式都是在动词的词尾直接加ed;
2.以辅音加结尾的动词,先变y为i,然后加ed;
3.以“辅元辅”结构结尾的动词,双写最后一个字母再加ed;
4.以e结尾的动词在词尾直接加d;
5.不规则变化.
现在我们来看看一些常见的不规则动词的过去式:
be-was/were become-became begin-began
bring-brought buy-bought catch-caught
come-came do-did draw-drew
drink-drank eat-ate feel-felt
find-found fly-flew get-got
give-gave go-went have-had
leave-left make-made read-read
ride-rode run-ran say-said
see-saw sing-sang sit-sat
sleep-slept speak-spoke stand-stood
swim-swam take-took teach-taught
think-thought throw-threw write-wrote
一般过去时的否定形式:
1.一般过去时的否定形式相互要是在主语后面加did not.
I watched TV yesterday.
I did not watch TV yesterday.
2.如果有be动词就直接在be动词的后面加not就可以了.
She was a nurse five years ago.
She was not a nurse five years ago.
3.如果有情态动词,就在情态动词后面直接加not.
They could swim in the sea.
They could not swim in the sea.
一般过去时的一般疑问句:
1.将助动词did提前,后面的动词保持原形不变.
They learned English before.
Did they learn English before?
Yes, they did./No, they didn’t.
2.如果句子中有be动词就直接将它提前.
They were good friends last year.
Were they good friends last year?
Yes, they were./No, they weren’t.
3.如果句子中有情态动词,直接用情态动词提问.
Should I do my homework?
Yes, you should./No, you shouldn’t.
与一般过去时连用的时间状语:
1.yesterday, last night (week, year, month, Sunday…), then, at that time, at that moment, just now, a few days (weeks, months, years) ago…
2.由after, before, when, while引导的时间状语从句.
3.一般过去时也可以与today, this week (month, year)等时间状语从句连用,但这些时间状语应指过去.
