动词过去式的构成规则（规则变化）规则动词词尾加ed,有三种读音：1.在清辅音后读作/t/例:ask→askedwatch→watched2.在浊辅音、其他辅音和元音后读作/d/例:clean→cleanedstay→stayed3.在t/d后面读作/id/例:want→wantedvisit→visited1.一般在动词词尾加ed例：clean→cleanedwatch→watched2.以e结尾的动词，只加d例：live→livedclose→closed3.以辅音字母加y结尾的动词,改y为i,再加ed例：study→studiedcarry→carried4.末尾只有一个辅音字母的重读闭音节词，先双写这个辅音字母，再加-ed例：stop→stopped

【巧学妙记】规则动词过去式的构成过去式构成有规律，一般词尾加-ed。如若词尾有个e，直接加-d就可以。辅音字母y结尾，变y为i加-ed。一辅重闭作尾巴，双写之后加-ed。

常见的不规则动词过去式(详见课本P152不规则动词表)am/is→wasare→weredo→didhave→haddrink→dran
