小学英语语法知识点汇总：一般过去时

　　一般过去时

　　主要用来表示在特定过去时间中一次完成的动作或一度存在的状态，也可表示过去的习惯动作。它与现在时间不发生关系，它表示的动作或状态都已成为过去，现已不复存在。它经常与表示过去的时间连用。如：I went to a park yesterday.  I read a book last night. I watched TVyesterday evening.I went on a big trip last weekend.  I failed my Chinese test.

　　☆注意☆　一般过去时主要体现在动词的形式要用过去式，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 , visited②　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　study –studied carry – carried worry – worried （play、stay除外）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：

　　sing – sang ,   eat – ate ,  see – saw ,   have – had ,   do – did ,

　　go – went ,   take– took ,   get – got ,    read – read ,    am/is – was ,   are – were ,    say – said ,   tell – told ,   come – came ,  drink – drank
