一般過去時(shí)
(一)定義
一般過去時(shí)主要用來表示過去某個(gè)時(shí)間里發(fā)生的動(dòng)作或狀態(tài)。常與表過去的時(shí)間狀語連用。如:
· He came here yesterday.
· We visited Paris last week.
(二)基本結(jié)構(gòu)
一般過去時(shí)的句子結(jié)構(gòu)一般為:
主語+was/were/did+其他成分
如:
· She was at the party yesterday evening.
· They went to the park this Friday.
· He told me that I could leave for Shanghai.
(三)主要用法
1、表過去某個(gè)時(shí)間會(huì)發(fā)生的動(dòng)作或狀態(tài)
· The dog had a house of its own just now.
· She came to see me yesterday afternoon.
2、表過去習(xí)慣性或經(jīng)常性的動(dòng)作或狀態(tài)
· I smoked a lot when I was a college student.
· You were always at home on weekends last month.
【注意】
過去習(xí)慣的表達(dá)經(jīng)常會(huì)用到used to do,但用了這個(gè)短語,往往意味著現(xiàn)在這個(gè)習(xí)慣已經(jīng)沒有了。如:
§ He used to smoke a lot. (他過去煙癮很重。)
(四)動(dòng)詞的過去式
動(dòng)詞過去式的變化規(guī)則主要有:
1、+ed
大部分動(dòng)詞都直接在詞尾加ed。如:played、worked
2、+d
以不發(fā)音的e結(jié)尾的動(dòng)詞,直接在詞尾加d。如:deleted(刪除)、faded(消逝)
3、+ied
以輔音+y結(jié)尾的動(dòng)詞,要改y為i,再加ed。如:studied、cried
4、+ked
以ic結(jié)尾的動(dòng)詞,要先加k再加ed。如:panicked(恐慌)、trafficked(販運(yùn))
5、雙寫+ed
當(dāng)單詞以重讀閉音節(jié)結(jié)尾時(shí),要雙寫最后一個(gè)輔音字母,再加ed。如:stopped、padded(填塞)
6、不規(guī)則
不規(guī)則的動(dòng)詞關(guān)鍵在于多識(shí)記,如:put-put,come-came,go-went,take-took,lend-lent。
(五)標(biāo)志性詞語
1、yesterday系列
這類時(shí)間狀語主要有:yesterday、yesterday morning/afternoon/evening、the day before yesterday等。如:
· I met an old friend on the street the day before yesterday.
· The band gave a performance at the bar yesterday evening.
2、last系列
這類時(shí)間狀語主要是指由“last+時(shí)間單位”引導(dǎo)的短語:last Wednesday / last week / last month / last summer / last year等。如:
· They spent their holiday in Berlin last month.
· She left for Beijing on business last week.
3、ago系列
這個(gè)短語的意思是“多長時(shí)間之前”,其結(jié)構(gòu)為:時(shí)間段+ago。如:
· The train left five minutes ago.
· The plane arrived an hour ago.
4、just now
該短語表示“剛才”。如:
· Our English teacher gave us a lecture on British accent just now.
· The principal told us just now that there would be a great change in our school this coming summer.
5、the other day
· I left my handbag on the train to Tokyo the other day.
· She ran into her primary school English teacher at the party the other day.
6、“this+過去時(shí)間”系列
· She visited the museum this Thursday.
· My aunt came here this Tuesday.
(六)句型轉(zhuǎn)換
1、was/were
當(dāng)句子的謂語動(dòng)詞是由was/were引導(dǎo)時(shí),was/were就相當(dāng)于助動(dòng)詞,其否定句直接在后面加not即可,疑問句只要把was/were提前即可。如:
· 原句:Kerry was in her hometown last Sunday.
· 否定句:Kerry wasn't in her hometown last Sunday.
· 一般疑問句:Was Kerry in her hometown last Sunday?
· 劃線部分提問:Where was Kerry last Sunday?(提問in her hometown)
2、did
當(dāng)句子的謂語動(dòng)詞為實(shí)義動(dòng)詞(行為動(dòng)詞)時(shí),其否定句和疑問句的變化要借助助動(dòng)詞did。如:
· 原句:Kerry showed me around her hometown last Sunday.
· 一般疑問句:Did Kerry show you around her hometown last Sunday? Yes, she did. / No, she didn't.
· 劃線部分提問:When did Kerry show you around her hometown? (提問last Sunday)
3、非was/were/did
當(dāng)句子的謂語動(dòng)詞為非was/were/did的動(dòng)詞時(shí)(即謂語動(dòng)詞中含有情態(tài)動(dòng)詞或助動(dòng)詞時(shí)),其否定句和疑問句的變化與was/were的情況相同。如:
· 原句:It could be worse.
· 否定句:It couldn't be worse.
· 一般疑問句:Could it be worse? Yes, it could. / No, it couldn't.
· 劃線部分提問:What could be worse?(提問it)
