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:guess—guesses, 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
