he、she、it、they和人名类(如:
Peter、Jane、myfather等)
结合以上知识,第三人称单数就是he、she、it和单个的某人,也包括单个的动物、东西等。
二、动词为什么要变成相应的三单形式?
在一般现在时中,跟在第三人称单数后面的动词也要变成相应的三单形式,例如:
IwatchTVeveryday.如果主语是三单,动词要变化:
HewatchesTVeveryday.
ShewatchesTVeveryday.
JanewatchesTVeveryday.
三、动词三单的变化规则
1、一般情况下直接加s,如speak-speaks,like-likes,play-plays
2、以s,x,sh,ch,o结尾的加es,如wash-washes,go-goes,do-does,watch-watches
3、以辅音字母+y结尾的,改y为i再加es,如study-studies,try-tries
4、特殊变化,如have-has
四、does和doesn’t在句子中的用法
否定句:
主语+don’t/doesn’t+动词原形+(其他)。
如:
Idon’twatchTV.我不看电视。
当主语为第三人称单数时,要用doesn’t构成否定句。
Hedoesn’twatchTV.他不看电视。
注意doesn’t后面用动词原形watch,而不是watches
一般疑问句:
Do/Does+主语+动词原形+(其他)。
DoyouwatchTV?
Yes,Ido./No,Idon’t.
当主语为第三人称单数时,要用does构成一般疑问句。
DoesshewatchTV?
Yes,shedoes./No,shedoesn’t.
特殊疑问句:
疑问词+一般疑问句。
Howdoyougotoschool?
Bybike.
HowdoesJanegotoschool?
Bybus.
