谁知道以下英语过去式
saw,took,brought,did,sat,began,sang,sung,drew,slept,swam,很抱歉英语中的be动词没有过去式。stopped,staked,went,read,stopped,let,thought,put,sank,sunk,caught,got,studied,liked
did后面understand为什么不用过去式
did是do的过去式,已经表示过去了,所以就不understand 的过去式了
smell的过去式
smell
动词过去式:smelled/smelt
动词过去分词: smelled/smelt

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。
一、规则动词
1、一般动词直接加-ed;
2、以e结尾的动词直接加-d,e.g.dance-danced;
3、辅音字母加y结尾的,变y为i再加ed,e.g.study-studied;
4、以重读闭音节结尾,末尾只有一个辅音字母(字母w,y,x除外),双写这个辅音字母加-ed;
5、以l结尾的动词,若以非重读音节结尾,则末尾的字母l双写与不双写均可;其中不双写的是美式拼写。。
6、部分以-p结尾的动词同样遵循第5条,这类词多由“前缀+名词”构成。
二、不规则动词
1、动词过去式与原形相同;
2、动词过去式以-ought或-aught结尾;
3、动词过去式由原形结尾的-end变为-ent;
4、动词过去式以-elt,-eft,-ept结尾;
5、动词过去式与原形比较,其中一个元音字母发生改变;
6、动词过去式以-ew结尾;
7、动词过去式-ee-变为-e-。
