二动词过去式的构成规律(一)规则动词的过去式1,大凡情况下,在动词原形后面加-ed;Look--- lookedplay----playedstart--- startedvisit—visited2,以不发音e结尾的动词,在词尾直接加-d;Live—liveduse---used3,以“辅音字母+y”结尾的动词,先将y改成i,再加–ed;Study---studiedtry—triedfly---flied4,以重读闭音节(即辅音+元音+辅音)或r音节结尾,末尾只有一个辅音字母的动词,要先双写这个辅音字母后,再加–ed。
Stop---stoppedplan---plannedpreferred(二)不规则动词的过去式1改变动词中的元音;Begin--- begandrink---drankcome---cameeat---ateGrow---grewrun---ranknow---knewwin---wonspeak---spokeTake ---tookwrite ---wroteget---got2变词尾的-d为-tBuild---builtlend---lentsend---sentspend--spentbend--bent3与动词原形一样;Cut---cutput---putcost----costhurt---hurtshut---shut4变-ay为—aid(少数动词)Say---saidpay---paidlay---laid5采用例外词根;Sell--- soldteach----taughtbuy----bought6其他Am/is ---wasare---werehave/has--- haddo---did二加–ed后的读音方法1 ed加在清辅音后面读/t/Finished/-t/help /-t/asked/-t/2 ed加在浊辅音或元音结尾的,读/d/Played/-d/lived/-d/enjoyed/-d/3 ed加在/t/或/d/后面,读/id/Wanted /-tid/needed/-did/visited /-tid/过去时练习:写出下列动词的过去式Is\am______fly___plant_____are_____drink_____Play______go____make______does_____dance_____Worry______ask____taste______ _ eat_____draw_____Put_____throw______kick_______pass_____do______用所给动词的合适形式填空1 We_____ (live) in Japan last year.2 Susan_____(stop) the car on the street yesterday.3 My mother____(clean) my room and I _____( study) for the English testlastSunday.4 What____ you_____(do) last night?5 On Saturday morning I ____(play) football二用括号内所给动词的合适形式填空(1)May_____(finish) her homework very late yesterday evening.(2)HanMei_____(bring) her pet to the park that day.(3)His father______(buy) a new computer for him last week(4)Miss Du______ (walk) to work every day last term.(5)We____(move) to Shenyang 8 years ago.(6)_____ you _________(have) bread for breakfast this morning?(7)She_______(give) me a nice present last night.(8)The police______(stop) the car and_____(catch) the thief (小偷)just now.(9)Tom ____(carry)water for the old man last Saturday.(10)Uncle Wang______(come)into the room and______(find) somethingtoeat.(11)Lily______(study)in the classroom for two hours and then____(leave).(12)Jimmy______(do) a lot today.
