1、一般情况下,在动词词尾直接加-ing,如:
①check(检查;核对)—checking
②call(叫;打电话给)—calling
③rain(下雨)—raining
2、以一个字母-e结尾的单词,去掉字母-e,再加-ing,但是双写-ee结尾的,要直接加-ing。如:
①move(移动;感动)—moving
②like(喜欢;愿意)—liking
③close(关闭;结束)—closing
3、以重读闭音节结尾,即“辅+元+辅”结尾的动词,先双写末尾的辅音字母,再加-ing。如:
①stop(停止,阻止)—stopping
②beg(乞求,乞讨)—begging
③drop(滴落;投下)—dropping
4、以-y结尾的动词直接加-ing。如:
①carry(携带;拿,刊登)—carrying
②enjoy(喜欢;享有)—enjoying
③dry(弄干)—drying
5、以-ie结尾的动词,把-ie改为-y,再加-ing。如:
①die(死)—dying
②lie(说谎;躺)—lying
③tie(捆,绑)—tying
