动词现在分词的构成规律
1) 一般情况下，在动词原形后直接加-ing. 如：work—working (工作) do—doing（做）
play—playing（玩）
2) 以不发音的字母e结尾的动词，去掉e，再加-ing. 如：
dance—dancing（跳舞） come—coming（来）
(但动词词尾是字母组合ee的,就不能去掉词尾e，而应直接加-ing。例如:  see－seeing)
3) 重读闭音节单词，如果末尾只有一个辅音字母，则双写这一字母，再加-ing. 如：
get—getting(得到) shop—shopping（购物）
run—running（跑） swim—swimming （游泳）
