1、Unit 3 Language in use 一般過去時(shí)(二)一般過去時(shí)(二) 在上個(gè)模塊中,我們學(xué)過了be動(dòng)詞的過去式為was/were,那么行為動(dòng)詞的過去式是如何構(gòu)成的呢?帶有行為動(dòng)詞的一般過去時(shí),沒有人稱和數(shù)的變化,其謂語動(dòng)詞用過去式。請(qǐng)觀察下面兩個(gè)例句:Goldilocks picked some flowers.金鳳花姑娘摘了些花。She decided to go for a walk in the park with her basket. 她決定帶著她的籃子到公園里散步。例句中畫線的單詞都是動(dòng)詞的過去式形式。動(dòng)詞的過去式構(gòu)成方法各不相同,如下表: 1. 規(guī)則動(dòng)詞過去式的變化規(guī)律
2、規(guī)則動(dòng)詞過去式的變化規(guī)律變化規(guī)律動(dòng)詞原形過去式一般動(dòng)詞詞尾加-edlisten, clean,finishlistened, cleaned, finished 2. 規(guī)則動(dòng)詞過去式構(gòu)成之后的讀音規(guī)則動(dòng)詞過去式構(gòu)成之后的讀音從上面我們可以看出規(guī)則動(dòng)詞構(gòu)成過去式之后都是以-ed結(jié)尾,但ed的讀音是不同的,分別有三種情況,即/t/,/d/,/Id/。以字母e結(jié)尾的動(dòng)詞后加-dlive, decide,arrive, movelived,decided,arrived,moved以輔音字母加y結(jié)尾的動(dòng)詞,y變?yōu)閕,再加-edcarry,hurry,worrycarried, hurried, wor
3、ried以元音字母加一個(gè)輔音字母結(jié)尾的重讀閉音節(jié)動(dòng)詞,先雙寫該輔音字母,再加-edstop, step,planstopped,stepped,planned(1)動(dòng)詞是由清輔音音素結(jié)尾的,加-ed之后,應(yīng)在原來的音標(biāo)之后加/t/。如:like/laIk/liked/laIkt/look/luk/looked/lukt/(2)動(dòng)詞是由濁輔音音素或元音音素結(jié)尾的,加-ed之后,ed應(yīng)讀/d/。如:clean/kli:n/cleaned/kli:nd/play/pleI/played/pleId/(1)動(dòng)詞是由清輔音音素結(jié)尾的,加-ed之后,應(yīng)在原來的音標(biāo)之后加/t/。如:like/laIk/li
4、ked/laIkt/look/luk/looked/lukt/(2)動(dòng)詞是由濁輔音音素或元音音素結(jié)尾的,加-ed之后,ed應(yīng)讀/d/。如:clean/kli:n/cleaned/kli:nd/play/pleI/played/pleId/(3)動(dòng)詞是由音素/t/或/d/結(jié)尾的,加-ed之后,ed應(yīng)讀/Id/。如:need/ni:d/needed/ni:dId/want/wnt/wanted/wntId/ 3. 行為動(dòng)詞一般過去時(shí)的否定句構(gòu)成行為動(dòng)詞一般過去時(shí)的否定句構(gòu)成如果要表示過去沒有做某事,則要用行為動(dòng)詞一般過去時(shí)的否定形式。根據(jù)行為動(dòng)詞一般現(xiàn)在時(shí)的構(gòu)成規(guī)律,可以判斷,行為動(dòng)詞的一般過去時(shí)
5、的否定形式也要加助動(dòng)詞來構(gòu)成。其結(jié)構(gòu)為:主語+didnt/did not+動(dòng)詞原形+其他。如:I didnt do the housework yesterday.昨天我沒有做家務(wù)。They didnt do their homework yesterday evening.昨天晚上他們沒有做他們的家庭作業(yè)。He didnt eat breakfast this morning.今天早上他沒有吃早飯。注意:助動(dòng)詞didnt(=did not)沒有人稱和數(shù)的變化,適用于所有的人稱,后跟動(dòng)詞原形。帶有行為動(dòng)詞的一般現(xiàn)在時(shí)的否定形式與帶有行為動(dòng)詞的一般過去時(shí)的否定形式有所不同,前者的否定句有兩種情況
6、:(1)主語不是第三人稱單數(shù)時(shí):主語+dont/do not+動(dòng)詞原形+其他。(2)主語為第三人稱單數(shù)時(shí):主語+doesnt/does not+動(dòng)詞原形+其他。 4. 一般過去時(shí)的一般疑問句一般過去時(shí)的一般疑問句(1)構(gòu)成帶有行為動(dòng)詞的一般過去時(shí)態(tài)變一般疑問句同一般現(xiàn)在時(shí)的一樣,也是通過在句首加助動(dòng)詞構(gòu)成。不同的是,一般現(xiàn)在時(shí)態(tài)助動(dòng)詞用do/does,一般過去時(shí)態(tài)助動(dòng)詞用did。然后把謂語動(dòng)詞由過去式還原成動(dòng)詞原形,并在句末加問號(hào)。(2)結(jié)構(gòu)一般疑問句的結(jié)構(gòu)及其肯定與否定回答:Did+主語+謂語動(dòng)詞原形+其他?肯定回答:Yes, 主語+did.否定回答:No, 主語+didnt.如:I did
