动词过去式的构成方式有规律和不规则两种。规律的动词过去式构成方法是在动词原形后加-ed。例如：- talk → talked (谈话)- play → played (玩耍)- want → wanted (想要)而不规则动词过去式则没有规律，需要单独记忆。例如：- be → was/were (是)- go → went (去)- do → did (做)下面是一些常用动词的过去式：- eat → ate (吃)- sleep → slept (睡觉)- run → ran (跑)- see → saw (看到)- give → gave (给予)- think → thought (思考)- take → took (拿走)- make → made (制造)需要注意的是，在第三人称单数时，动词过去式的构成方式与现在式不同。一般来说，第三人称单数动词过去式在动词原形后加-ed。例如：- walk → walked (步行)- love → loved (爱)- talk → talked (谈话)总之，掌握动词过去式构成方式是学好英语语法的基础，需要通过大量的练习和记忆才能提高英语语言能力。
