（2）一般過去時:

　　動詞過去式詳解   動詞的過去式的構成規則有：

　　Ａ、規則動詞

　　①    一般直接在動詞的后面加ed：如　worked , learned , cleaned , visited

　　②　以e結尾的動詞直接加d：如　lived , danced , used

　　③    以輔音字母加y結尾的動詞要改y為i再加ed（此類動詞較少）如　study - studied carry - carried worry - worried  （注意play、stay不是輔音字母加y,所以不屬于此類）

　　④  雙寫最后一個字母（此類動詞較少）如　stopped

　　Ｂ、不規則動詞（此類詞并無規則，須熟記）小學階段要記住以下動詞的原形和過去式：sing - sang ,  eat - ate ,

　　see - saw , have - had , do - did , 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
