第三人称单数讲解以及练习题

在一般现在时中, 当主语是第三人称单数形式时,行为动词用第三人称单数形式,即加-s 或 –es. 具体方法如下:

1.一般情况下,直接加 -s.如:

look---looks play---plays see---sees

2. 以 sh,ch,s,x或o结尾的词后加-es.如:

guess –guesses teach—teaches do---does go---goes 3.以辅音字母加-y结尾的, 先把y变成i,再加 -es.如: study---studies fly---flies 二. 哪些主语是第三人称单数

1.人称代词he, she, it是第三人称单数. 1).He likes watching TV.他喜欢看电视. 2).She has a black coat.她有一件黑色外套. 3). It looks like a cat. 它看起来像只猫.

2. 单个人名.地名或称呼作主语时,是第三人称单数形式.如: 1).Han Mei looks like her mother.韩梅看起来像她的母亲. 2).Beijing is in China. 北京在中国.

3). Uncle Wang often makes cakes.王叔叔经常做蛋糕. 3.单数可数名词或 “this/that/the + 单数可数名词” 作主语时,是第三人称单数. 如: 1).This book is yours.这本书是你的. 2).That car is red. 那辆汽车是红色的. 3).A cat comes in.一只猫进来了.

6. 当数字或字母做主语时,看做第三人称单数.如: 1).“6” comes after “5”. “6”在“5”后面.

2).“L” comes before “O”.“ L”在“O”前面. 关于do和does的使用方法：

1）第三人称单数用了 does 后面就不用动词的s形式了,而用动词原形.

2）变为疑问句,要在句首加\"do\" does ; 变为否定句, 要在动词前面加\"do not, does not\可以简写为 \"don't, doesn’t”.
