2、以不发音e结尾的动词,在词尾直接加-d;如:live→lived use→used;
3、以“辅音字母 y”结尾的动词,先将 y 改为i ,再加 –ed;如:study→studied, try→tried fly→flied
4、以重读闭音节(即辅音 元音 辅音)或r音节结尾,末尾只有一个辅音字母的动词,要先双写这个辅音字母后,再加 –ed。如:stop→stoppedplan→planned;
(二)不规则动词的过去式
1、改变动词中的元音;
begin→began drink→drank come→came eat→ate grow→grew run→ran know→knew win→won speak→spoketake→took write→wrote get→got
2、变词尾的–d 为–t ; build→built lend→lent send→sent spend→spent bend→bent
3、与动词原形一样; cut→cut put→put cost→cost hurt→hurt shut→shut
4、变-ay 为-aid (少数动词); say→said pay→paid lay→laid
5、采用不同词根;sell→sold teach→taught buy→bought
6、其他。如:am/is→was are→were have/has→had do→did
