过去式和现在分词 详细版课件

1、动词过去式复习同学们，想一想：动词的过去式有哪些变化规则是什么呢？我们一起来探讨学习吧！A：规则变化 一般直接在动词的后面加 ed：如played, worked, wanted, learned, 以e结尾的动词直接加d:如 danced(跳舞), used (使用), 以辅音字母加y结尾的动词要改y为i再加ed:如 study (学习) studied, carry (拿，抱) carried worry (担心) worried思考： play, stay 的过去式怎么变呢？(注意: play, stay不是辅音字母加y, 所以过去式直接+edplay - played, stay -

2、stayed 双写最后一个字母(此类动词较少): 如 stop(停止) - stopped skip(跳绳)-skipped 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:fly( 飞 ) _, meet (见面，遇见) _see (看见)_, feed (喂养) _get ( 拿到，获得 )_, fall(跌落，跌倒)_eat ( 吃 ) _ run( 跑步) _say(说) _ give( 给 ) _throw(投，扔)_ sit( 坐 ) _swim( 游泳) _ think (想，思考) _buy(买) _ sing|( 唱歌 )_flewmetsaw
