3、g，通常是在原形词尾直接加-ing构成：coughcoughing，climbclimbing，standstanding，fightfighting2以-e结尾的动词（1）如果动词原形以一辅音加一不发音的-e结尾，一般应去掉e再加ing：writewriting，hopehoping，carecaring，starestaring planeplan-ing，havehaving，savesaving， produceproducing， breathebreathing（2）以-ie结尾的动词应先将e去掉，将i变成y然后再加-ing：diedying，tietying，vievying，l

4、ielying（3）以-ee，oe，ye结尾的动词加-ing时应保留词尾e：seeseeing，fleefleeing，freefreeing，agreeagreeing，hoehoeing， dyedyeing，eyeeyeing（4）以-ue结尾的动词大多应先去e再加-ing：suesuing，imbueimbuing，construeconstruing，pursuepursuing，rueruing有时，词尾e可去掉也可保留：gluegluing或 glueing，cuecuing或 cueing， blueblueing或 bluing，truetruing或trueing，clue

5、clueing或cluing3以一元音加一辅音结尾的动词（1）如果动词最后一音节为重读闭音节，最后一个字母需要重复：runrunning， stopstopping， hophopping， planplanning，starstarring， controlcontrolling但辅音x是个例外，无需重复（x其实起着两个辅音的作用）：taxtaxing，relaxrelaxing（2）如果动词最后一个音节为次重读音节，最后一个字母有时也重复：kidnapkadnapping或kidnaping，programprogramming或programing（3）如果动词最后一个音节为非重读音节，

7、wdrawing， employemploying5以-ic结尾的动词应先在字母c后加一字母k再加-ing：frolicfrolicking，panicpanicking，mimicmimicking，picnicpicnicking，traffictrafficking这主要是为在动词后加-ing之后保留/k/这个音。若不在字母c后加字母k而直接加-ing，字母 c的发音就不再是/k/，而是/s/：相应练习一.写出下列动词的-ing形式work_ visit_ play_ study_ dance_ have_ travel_ take_ drop_ sing _ shop_ swim_li
