　　小学英语一般过去时语法详解

　　一、概念

　　表示在的过去某个时间里所发生的动作或存在的状态。通常在句子里找到表示过去时间的词或词组。如：yesterday，yesterday morning，yesterday afternoon，yesterday evening，the day before yesterday（前天），last night，last week，last month， last year，a moment ago（刚才），just now（刚才）， two days ago，a week ago，in 1990等。 如： I went to bed at eleven last night.昨晚我11：00睡觉。

　　二、动词过去式的构成规律

　　(一)规则动词的过去式

　　1、一般情况下，在动词原形后面加-ed；如：look→looked play→playe d；

　　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→triedfly→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（后附不规则动词变化表）

　　1、改变动词中的元音；

　　begin→began drink→drank come→came eat→ate grow→grew run→ran know→knew win→wonspeak→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
