想知道过去式变化规则口诀

规则动词的过去式变化如下：　　

一般情况下，动词词尾加ed，如：　　

work—worked；play—played；want—wanted；act—acted　　

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；　　

以辅音字母+y结尾的动词，把y变为i再加ed，如：　　

studiedtriedcopiedjustifiedcriedcarriedembodiedemptied　　

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：　　

stoppedbeggedfretteddraggeddroppedplanneddotteddripped　　

（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-ge,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/。

规则动词词尾加-ed有三种读音：

1.在清辅音后读作[t]。

如：asked,helped,watched,stopped　　

2.在浊辅音和元音后读作[d]。

如：enjoyed,studied,moved,called　　

3.在t/d后读作[id]。

如：wanted,needed

不规则动词的过去式大体上归纳有以下六条记忆法：　　

1.以t结尾的词，过去式与原形相同。

如：put—put,let—let,cut—cut,beat—beat

2.以d结尾的词，把d变成t。

如:build—built,lend—lent,send—sent,spend—spent　　3.以n结尾的词，在词后加t。

如：mean—meant,burn—burnt,learn—learnt　　

4.以ow/aw结尾的词，把ow/aw变成ew。

如：blow—blew,draw—drew,know—knew,grow—grew　　

5.含有双写字母的词，将双写改为单写，在词尾加t。

如：keep—kept,sleep—slept,feel—felt,smell—smelt　　

6.含有元音字母o/i的词，将o/i变成a。

如：sing—sang,give—ge,sit—sat,drink—drank　　

但也有例外，如get的过去式是got，与第一条不符，仅仅是大多数动词符合。
