典型例題
---- Your phone number again? I ___ quite catch it.
---- It's 69568442.
A. didn't B. couldn't C. don't D. can't
答案A. 本句雖沒(méi)有明確的時(shí)間狀語(yǔ)，但從語(yǔ)意上看 出，在聽(tīng)的時(shí)候沒(méi)有聽(tīng)懂這個(gè)動(dòng)作發(fā)生在過(guò)去，因此應(yīng)用過(guò)去時(shí)。
10)有些句子，雖然沒(méi)有表示過(guò)去確定時(shí)間的狀語(yǔ)，但實(shí)際上是指過(guò)去發(fā)生的動(dòng)作或存在的狀態(tài)的話，也要用過(guò)去時(shí)。
I didn't know you were in Paris.
我不知道你在巴黎。
(因?yàn)樵谡f(shuō)話時(shí)，我已經(jīng)知道你在巴黎了。這句話指的是說(shuō)話之前，所以只能用過(guò)去時(shí)表示。實(shí)際上，這句話暗指：But now I know you are here.)
I thought you were ill.
我以為你病了呢。
(這句話應(yīng)是在說(shuō)話之前，我以為你病了。但是現(xiàn)在我知道你沒(méi)病)

常見(jiàn)錯(cuò)誤如下:
一 把動(dòng)詞變成過(guò)去式易出錯(cuò)
例: 1 They stoped (stop) talking just now.
2 They plaied (play) football yesterday.
答案: 1 stopped 2 played
解析:我們可以記住下面的口訣:"動(dòng)詞變成過(guò)去式,雙寫規(guī)律要牢記;y前若是輔音字,y變i加-ed;y前若是元音字,只須直接加-ed."
二忘記把動(dòng)詞變成過(guò)去式
例: I fly (fly) kites on the afternoon of Sunday.
答案: flew
解析:我們可以記住下面的口訣:"一般過(guò)去時(shí)態(tài)里,過(guò)去形式莫忘記".

例: He taughts (teach) me English last year.
答案: taught
解析:行為動(dòng)詞的過(guò)去式無(wú)人稱和數(shù)的變化.即使主語(yǔ)是單三人稱,也和其它人稱所用動(dòng)詞的形式一樣.
五易與現(xiàn)在完成時(shí)弄混
例: 我看過(guò)這部電影
I saw(see) the film.
答案: I have seen (see) the film.
解析:"我看過(guò)這部電影"說(shuō)明我了解這部電影的內(nèi)容,強(qiáng)調(diào)現(xiàn)在的情況,應(yīng)用現(xiàn)在完成時(shí);
一般過(guò)去時(shí)態(tài)的句子只是說(shuō)明我看了這場(chǎng)電影,與現(xiàn)在無(wú)關(guān)..
