1、一般情况下,直接在动词后加－ingwork ---- workingsleep ----- sleepingstudy ----- studying2、动词以不发音的－e结尾,要去－e加－ingtake ----- takingmake ----- makingdance ----- dancing
3、重读闭音节的动词,要双写词尾字母,再加－ingcut ----- cuttingput ----- puttingbegin ------ beginning
4、以－ie结尾的动词,把变成y再加－inglie ----- lyingtie ----- tyingdie ----- dying
