一般现在时主语第三人称时的动词变化

(名词的复数变化规律)①在一般现在时中，当主语为第三人称单数时，动词要用―s‖型（即第三人称单数形式）。②所谓动词―s‖型的构成，可按名词变复数的规则来记，即：

1）在动词尾直接加 s。如：play—plays，want—wants，work—works，know—knows，help—helps，get—gets，reads.2）以字母s、x、ch,sh或o结尾的动词加-es；如：gue—guees，fix—fixes，teach—teaches，brush—brushes，go—goes，do—does，watch—watches，catch—catches 3）以辅音字母＋y结尾的动词，先变y为i，再加-es。如：study—studies，carry—carries，fly—flies，worry—worries 不规则变化：have----has ③④强调如何将主语是第三人称单数的肯定句变为否定和疑问句。现举例说明（用划线部分来说明顺口溜）：

1）His mother works in a factory．>>>>>>>>>>>>>>His mother doesn’t work in a factory． Does his mother work in a factory？

2）Mr Li teaches us English．>>>>>>>>>>>>>Mr Li doesn’t teach us English． Does Mr Li teach you English？

3）My brother studies maths well．>>>>>>>>>>>My brother doesn't study maths well． Does your brother study maths well？ 二．动词ing形式变化小结：

1、大多数动词直接在词尾加-ing，比如：go-going, work-working,study-studying,look-looking,do-doing,eat-eating,play-playing,read-reading,wash-washing,plant-planting,borrow-borrowing,pick-picking,paint-painting,cry-crying,took-tooking(v.拿，占领，接受）climb-climbing

2、有的以不发音的e字母结尾的动词，要去掉e再加-ing，比如：make-making, write-writing, skate-skating,close–closing, come-coming, make–making,take-taking，have-having,dance-dancing, smile-smiling,ride-riding,become-becoming, 若结尾的e 发音,就不能去掉,如：see-seeing

3、以重读闭音节结尾，末尾只有一个辅音字母的动词，要双写这一辅音字母，再加-ing。如：run-running, swim-swimming,get – getting,sit–sitting,put–putting,begin–beginning,hit-hitting stop-stopping

如果结尾是元音字母加辅音字母组合,就直接加-ing。比如：drawing, playing
