一般过去式d的用法及的不规则动词的过去式
表示一般过去式的动词通常用动词的过去式形式来表示,而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。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;want— 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; 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:
studied 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!二.时间状语:yesterday, the day before yesterday, two days ago, long long ago,a minute ago,last year(week, month), just now, at that time, in those days.三.过去时的用法:1.有确定的过去时间状语时要用过去式。

2.表示过去连续发生的动作时,要用过去式。
例:The boy closed the door, turned off the window, and then went to bed.
3. 表示过去一段时间内经常或反复的动作,要用过去式。
例:She often came to help me at that time.
四.一般过去式的构成形式:☆Be动词的过去式: (1)肯定句:主语+ be动词的过去式(was, were)
