过去式怎么变,
过去式怎么变,
过去式怎么变,
(1)一般情况下,动词词尾加 ed ,如:play-played;want- wanted; act-acted
(2)以不发音的 e 结尾动词,动词词尾加 d,如:move-moved; decide-decided; decline-declined; hope-hoped;
(3)以辅音字母 + y结尾的动词,把y变为i 再加ed,如:tried copied justified cried carried embodied emptied
(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:
stopped begged fretted dragged dropped planned dotted dripped
(5)注:不规则动词的过去式变化规律性不强,须多加记忆.
go - went,make - made,get - got ,buy - bought ,come - came ,fly-flew ,is/am-was,are-were ,see-saw,bring-brought,do-did,teach-taught,think-thought,say-said,sit-sat.read-read,spend-spent,eat-ate,give-gave,sit-sat,tell-told,write-wrote,feel-felt,find-found,hear-heard,know-knew,
put-put,grow-grew,take-took,catch-caught,come-came,become-became,swim-swam,sweep-swept,sing-sang,draw-drew,
以上的(1)至(4)条中的发音均有改变,具体分别有/d/ /t/ /id/.
而不规则动词的过去式的发音则略有不同,但是有些还是按照一定规律变化的.如以上的:make - made,get - got ,buy - bought ,come - came ,fly-flew ,bring-brought,teach-taught,think-thought,say-said,sit-sat.read-read,spend-spent,give-gave,tell-told,write-wrote,feel-felt,find-found,hear-heard,know-knew,put-put,grow-grew,take-took,catch-caught,come-came,become-became,swim-swam,sweep-swept,sing-sang,draw-drew.
仔细看一看,能发现它们的一些变化规律,也就是说不需要死记硬背这些过去式,知道了原型和变化规律,就可以写出来了.有的变化部分读音也是有规律的.分类记忆是对学习过去式很有帮助的!
有规则变化和不规则变化。
