小学英语重难点知识:动词过去式
动词的过去式的构成规则有:
A,规则动词
①一般直接在动词的后面加ed:如worked,learned,cleaned,visited
②以e结尾的动词直接加d:如lived,danced,used
③以辅音字母加y结尾的动词要改y为i再加ed(此类动词较少)如studystudied carrycarried worryworried(注意play,stay不是辅音字母加y,所以不属于此类)
④双写最后一个字母(此类动词较少)如stopped
B,不规则动词(此类词并无规则,须熟记)小学阶段要记住以下动词的原形和过去式:singsang,eatate,seesaw,havehad,dodid,go-went,take-took,buy-bought,get-got,read-read,fly-flew,am/is-was,
are-were,say-said,leave-left,swim-swam,tell-told,draw-drew,come-came,lose-lost,find-found,drink-drank,hurt-hurt,feel-felt
