初中英语如何把动词变成一般现在时和过去时的公式.

祁立云回答:
  1、一般情况下,动词词尾加-ed,如:   work---workedplay---playedwanted----wantedact----acted   2、以不发音的-e结尾动词,动词词尾加-d,如:   live---livedmove----movedtaste---tastedhope---hoped   3、以辅音字母+y结尾的动词,把-y变为-i再加-ed,如:   study---studiedcopy---copiedcry---criedcarry---carried   4、以一个辅音字母结尾的重读闭音节动词,双写词尾辅音字母,再加-ed,如:   stop---stopped   5、不规则动词的过去式变化规律性不强,须多加记忆.   go–wentmake–madeget–gotbuy-boughtcome-camefly-flew   不规则动词的过去式的构成   1.把动词原形中的i改为a,变成过去式.如:   begin—began,drink—drank,give—gave,ring—rang,sing—sang,sit—sat,swim—swam   2.把重读开音节中的i改为o,变成过去式.如:   drive—drove,ride—rode,write—wrote   3.改动词原形中的aw/ow为ew,变成过去式.如:   draw—drew,grow—grew,know—knew,throw—threw(动词show除外,show—showed)   4.动词原形中的e改为o,变成过去式.如:   get—got,forget—forgot   5.动词原形中的ee改为e,变成过去式.如:   feed—fed,meet—met   6.动词原形中的eep改为ept,变成过去式.如:   keep—kept,sleep—slept,sweep—swept   7.动词原形中的eak改为oke,变成过去式.如:   break—broke,speak—spoke   8.动词原形中的ell改为old,变成过去式.如:   sell—sold,tell—told   9.动词原形中的an改为oo,变成过去式.如:   stand—stood,understand—understood   10.以ought和aught结尾,且读音是〔:t〕的过去式.如:   bring—brought,buy—bought,think—thought,catch—caught,teach—taught   11.以ould结尾且读音为〔ud〕的情态动词过去式.如:   can—could,shall—should,will—would   12.把动词原形中的o改为a,变成过去式.如:   come—came,become—became   13.在动词原形后加d或t变成过去式,并且发生音变.如:   hear〔hi〕—heard〔h:d〕,say〔sei〕—said〔sed〕,mean〔mi:n〕—meant〔ment〕   14.动词的过去式与动词原形一样.如:   let—let,must—must,put—put,read—read〔red〕   15.不符合上述规律的动词过去式.如:   am,is—was,are—were,build—built,do—did,eat—ate,fall—fell,feel—felt,find—found,fly—flew,go—went,have/has—had,hold—held,leave—left,make—made,may—might,run—ran,see—saw,take—took   过去式“-ed”的发音规则   (1)动词词尾为“t,d”时,发/id/音,   want→wanted(要)need→needed(需要)   (2)动词词尾为清辅音时,发/t/音.   help→helped(帮助)laugh→laughed(笑)look→looked(看)   kiss→kissed(吻)wash→washed(洗)watch→watched(注视)   (3)动词词尾为t,d以外之浊辅音或元音时,发/d/音.   call→called(叫)stay→stayed(停留)cry→cried(哭)
