一般過去時主要表示過去某時發(fā)生的動作或情況。可以從以下幾個方面來理解:1)過去某個時間所發(fā)生的動作或存在的狀態(tài)。e.g. I bought a new shirt yesterday. He was a worker two years ago.2)過去一段時間內(nèi),經(jīng)常性或習(xí)慣性的動作。e.g. When I was a child,I often played with fire. Li Lei always walked to school last term.3)談到已故人的情況時多用過去時。e.g. Lu Xun was a great writer.4)有些發(fā)生時間不是很清楚的情況,實際是過去發(fā)生的,也應(yīng)用過去時態(tài)。e.g. What did you say?
另外,還可用過去時表示委婉的語氣。e.g. Could you lend me your pen?
其結(jié)構(gòu)是"主語+動詞的過去式"。be動詞的過去式為was, were;行為動詞的過去式有規(guī)則變化和不規(guī)則變化兩種,規(guī)則變化有以下幾種情況:1)直接在動詞原形末尾加-ed. e.g. work-----worked; ask------asked; 2)以e結(jié)尾的動詞只加-d. e.g. arrive-----arrived; like-----liked.3)末尾只有一個輔音字母的重讀閉音節(jié),應(yīng)先雙寫這個輔音字母,再加-ed. e.g. shop-----shopped; 4)以"輔音字母+y"結(jié)尾的動詞,先把y變成i,再加-ed. e.g. carry----carried; study------studied.有些動詞變過去式是不規(guī)則的,e.g. fly------flew; break-----broke; teach-----taught. 這些需要象生單詞一樣記住.
其句式變化分為兩種情況1)含有be動詞的依然在be上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980? 2)含有行為動詞的變否定句要在行為動詞前加助動詞didn't.,同時把動詞變成原形; 變一般疑問句,在句首加助動詞did,同時把動詞變成原形. e.g. I bought a gift for my mum yesterday. I didn't buy a gift for my mum yesterday. Did you buy a gift for your mum yesterday?
其時間狀語為yesterday或由其構(gòu)成的短語,e.g. yesterday morning; 由"last+時間"構(gòu)成的短語, e.g. last year; 由"時間段+ago"構(gòu)成的短語, e.g. three days ago; 另外,還有on the morning of Monday, just now等,以及一些表示過去時態(tài)的從句.注意,在賓語從句中主句為過去,一般從句也為過去.

常見錯誤如下: 一、把動詞變成過去式易出錯
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:"動詞變成過去式,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、忘記把動詞變成過去式
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:"一般過去時態(tài)里,過去形式莫忘記".
三、在句式變換時易出錯
例: 1 We didn't went (not go) out last Friday.
2 Did you had (have) a good time yesterday?
答案: 1 didn't go 2 Did have
解析:請記住口訣"見助動, 用原形."
四、易與單三人稱作主語的一般現(xiàn)在時弄混
例: He taughts (teach) me English last year.
答案: taught
解析:行為動詞的過去式無人稱和數(shù)的變化.即使主語是單三人稱,也和其它人稱所用動詞的形式一樣.
五、易與現(xiàn)在完成時弄混
例: 我看過這部電影
I saw(see) the film.
答案: I have seen (see) the film.
解析:"我看過這部電影"說明我了解這部電影的內(nèi)容,強調(diào)現(xiàn)在的情況,應(yīng)用現(xiàn)在完成時;
一般過去時態(tài)的句子只是說明我看了這場電影,與現(xiàn)在無關(guān)..
