人称单数形式
在一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单数形式,即常在动词原形后加
-s
或
-es
。但有些同学们对于哪些主语是第三人称单数还不十分清楚,现归纳总结如下:
一、人称代词
he, she, it
是第三人称单数。如:
He likes watching TV.
他喜欢看电视。
She has lunch at twelve.
她十二点吃午餐。
It looks like a cat.
它看起来像只猫。
二、单个人名、地名或称呼作主语;是第三人称单数。如:
①Han Mei looks like her mother. 韩梅看起来像她的母亲。
②Beijing is in China. 北京在中国。
③Uncle Wang often makes cakes. 王叔叔经常做蛋糕。
三、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:
①A horse is a useful animal.
马是有用的动物。
②This book is yours.
这本书是你的。
③That car is red.
那辆小汽车是红色的。
④The cat is Lucy's.
这只猫是露茜的。
四、不定代词someone, somebody, nobody, everything, something等及指示代词this,that作主语时,是第三人称单数。如:
①Everyone is here. 大家到齐了。
②There is something wrong with the watch. 这块手表有毛病。
③This is a pen. 这是一支钢笔。
④That is an eraser. 那是一块橡皮擦。
五、不可数名词作主语时为第三人称单数。如:
①The milk is in the glass. 牛奶在玻璃杯里。
②The bread is very small. 那面包很小。
一般现在时的肯定句中,主语为第三人称单数的动词变化主要体现在词尾的变化上,其规律大体有三点:
1.
一般情况下,直接在动词词尾
+s
,例如:
get→gets; take→takes
2.
以
s, sh, ch, x, o
结尾的动词,在词尾
+ es
,例如:
teach→ teaches; fix→fixes; go→goes
3.
以辅音字母
+ y
结尾的动词,变
y
为
i
,再
+ es
,如:
study→ studies; try→tries
