1、动词后加ing 的规则1英语动词加-ing,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,planeplaning,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:d
2、iedying,tietying,vievying,lielying(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, bluebluei
3、ng 或 bluing,truetruing或 trueing,clueclueing 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:kidnapkidnapping或 kidnaping,program
4、programming 或 programing(3)如果动词最后一个音节为非重读音节,最后一个字母大多无需重复:openopening,offeroffering,auditauditing 但在有些动词中,重复或不重复均可:worshipworshiping或 worshipping,focusfocusing 或 focussing,cancelcanceling 或 cancelling,traveltraveling 或travelling以非重读的-el 结尾的动词加-ing 时,英国英语习惯于重复词尾 l,而美国英语则习惯于不重复 1。4若动词以一元音加一半元音(y 或 w)结尾
5、,可直接加-ing:paypaying, throwthrowing,followfollowing, drawdrawing, 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/:其实,保持发音不变是英语中的一条一般规则。再如,在-ing 前面无论是增加、保留还是去掉一个字母,都倾向于保留原先的长元音或短元音的发音:hoping与 hopping staring与 starring playing与 planning
