一般在动词原形末尾加ing

　①一般在动词原形末尾加ing，如do→doing，sing→singing，comfort→comforting

　　②以不发音的e结尾的动词，先去e，再加ing，如dance→dancing，hike→hiking，write→writing,make→ making,take→taking

　　※注意※ 这里的e必须不发音，若发音，则不能去掉，如see→seeing

　　③以重读闭音节结尾的动词，并且末尾只有一个辅音字母，应双写这一字母，再加ing，如cut→cutting，swim→swimming

　　④以ie结尾的动词，要把ie变成y再加ing，如die→dying，lie→lying.不过也有y变ie加ing的。

　　⑤以ic结尾的动词，要把ic变成ick再加ing，如picnic→picnicking，traffic→trafficking

　　以上规则用一句话概括成的口诀就是：直接双写去e，ie变ying
