一般过去式 一、结构:
主 肯:S + 动词过去式 + O 谓 否:S + did not + 动词原形 + O 宾 疑:Did + s + 动词原形 + O ? 肯:S + was + 表语 主单 否:S + was not + 表语 主 疑:Was + s + 表语? 系 肯:S + were + 表语 表 主复 否:S + were not +表语 疑:Were + s +表语? 二、常见搭配:
Yesterday, last night/year/monday/sunday/week等,时间+ago。 三、动词过去式变化规则:
(一)规则动词的过去式变化如下: 1、一般情况下,动词词尾加 -ed ,如:
work ---worked play---played wanted----wanted act----acted 2、以不发音的 -e 结尾动词,动词词尾加 -d,如: live---lived move----moved taste---tasted hope---hoped 3、以辅音字母 + y结尾的动词,把-y变为-i 再加-ed,如: study---studied copy---copied cry---cried carry---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
(二)、不规则动词的过去式变化规律性不强,须多加记忆。 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
