行为动词一般现在时的变化珠村小学邓惠芳这里所说的行为动词,指的是除be动词、情态动词和助动词之外的全部动词。行为动词为数众多,主语为第三人称单数he,she,it时,词形有变化。当主语是第三人称单数时,行为动词的一般现在时通常有三种变化:1、多数在动词后加splay—playslike—likes,read-readssing-singsdance-dancescook-cookslook-looks2、以s,x,sh,ch,o结尾的动词加esgo—goeswash--washes,watch-watchescatch-catchesdo-does3、以辅音字母加y结尾,把y改i再加esfly—fliesstudy—studiestry-tries(这种变化与名词的单数变复数有点相像)那么,什么情况下用行为动词的一般现在时呢?当这个动作经常发生或表示习惯性的动作时,通常用一般现在时,它经常与表示频度的时间状语连用,如,当句子中有everydayeveryyear,onSunday,inthemorning,often,sometimes,usually,atoneo’clock,等词时,用一般现在时。Hegetsupat6o’clock.SheusuallywatchesTVintheevening.Sometimeshegoestoschoolbycar.TomoftenfliesakiteonSunday.只有第三人称单数动词才要变,其他人称(I,you,we,they)则用动词的原形。行为动词的一般现在时练习题班级姓名座号写出下列动词的正确形式:1、I(go)toschoolatseveninthemorning.2.Mike(do)hishomeworkateightintheevening.3.Hisfatheroften(read)booksinthelibraryonSaturday.4.Mymotherusually(watch)TVplaysathome.5.Mycousinsometimes(play)cardswithme.6.youoften(study)afterschool?Yes,Ido.7.MikeandTomusually(fly)kitesonSunday.8.They(go)toschoolbybuseveryday.9.She(go)toschoolbybuseveryday.10.Weusually(listen)totheradiointhemorning.11.Heusually(listen)totheradiointhemorning.12.heusually(listen)tothemusicathome?No,he.
