第三人称单数问题
不规则变化:do---- does have----has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:动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同,请认真观察。
1、大多数动词在词尾加“S”如:
①stop-stops [s] ; make-makes [s] ②read-reads [z] ; play-plays [z]
2、以辅音字母加“y”结尾的,要先将“y”变为“i”,然后在加“es”读[iz] 如:
fly-flies [z];carry-carries [z] study-studies [z]; worry-worries
3、以“s, x, ch, sh”结尾的,在词尾加“es”,发音为[iz] 如:
teach-teaches [iz]; watch-watches [iz]
4、以“o”结尾的动词,加“es”,如:
go-goes [z] do-does [z]
5.特殊的have--has
注:下面几个动词变为单数时,原词的元音部分的发音发生了较大的变化,请注意记忆。如:
1、do [du:]-does [dz]
2、say [sei]-says [sez]
以不发音字母“e”结尾的开音节词,如果尾音是[s],[z]时,加“s”后字母“e”发音,与所加“s”
一起读做[iz]。如:
close-closes [iz]
go do play jump swim run
put sing dance come get have
fly study read write look drink
eat walk like
第三人称单数用法:

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, everyone,somebody, nobody, everything, something,nothing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:
