第2篇:第三人称单数形式

第三人称单数形式

动词,在英语众多词汇中堪称变脸的高手,遇到不同的人称、数和时态,它总会以不同的面孔登场。本期将重点向同学们介绍在一般现在时的句子中,当主语是第三人称单数时,英语动词的变化规则。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

除上述规律外,还应注意下面三点:

1.动词 have,遇到主语是第三人称单数时,要用 has; 动词 be 的第三人称单数形式是is。

2.含有动词第三人称单数形式的句子变否定句时,要用 doesn't + 动词原形,如:

He goes to school at six in the morning.(变否定句)→ He doesn't go to school at six in the morning.3.对含有动词第三人称单数形式的句子提问时,要用助动词 does,如:

She goes home at five every day.(对划线部分提问)→ When / What time does she go home every day? 综上所述,只要我们洞悉了英语动词第三人称单数形式的变化规则,在一般现在时的句子中,我们都能从容应对,客随主“变”了。【动词第三人称单数的变化规则及发音规律 】

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”在清辅音后发音为[s],在浊辅音及元音后发音为 [z]。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-worries3、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”,读[z] 如: go-goes [z] do-does [z] 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]

二、对比词形变化中原词词尾变化之异同: 变“y”为“”现象 双写最后辅音字母现象 例词: ①baby-babies ②carry-carries ③study-studying

be动词包括:am,is,are。第三人称单数用 is; 过去式为 was;复数用are,过去式为were.【一般现在时中的动词第三人称单数形式】

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 gla.牛奶在玻璃杯里。②The bread is very small.那面包很小。

六、当数字或字母作主语时,看作第三人称单数。如: ①“6” is a lucky number.“6”是个吉利数字。②“I” is a letter.“I”是个字母。第三人称单数巩固练习

Example1: What ___(do)you have? I___(have)an apple.S: What do you have? I have an apple.T: Why? S: you 和 I都不是第三人称单数所以用do和have.Example2: What ____(do)Wang Bing have? He___(have)some cakes.S: What does Wang Bing have? He has some cakes.Wang Bing是单个人名,和he都是第三人称单数,所以用does和has.Example3: What ___(do)your brothers have? They ____(have)some toys.S1: does/ has T: Sorry.S: your brothers是复数,所以用do 和have 4.小组竞赛,看哪组同学做得最正确。

No, she _____(not).S2: Does, don’t.T: Sorry, she 是第三人称单数 don’t=do not,应该怎么变化呢? S: does not T: does not= doesn’t Example: ___(do)your father have a computer? No, he ____(not).S: Does, doesn’t T: 同样,我们也可以用don’t 和doesn’t来否定动词 Example: I __don’t__(not)like swimming.Tom __doesn’t__(not)like skating.6.Exercise: 1.We____(not)have time.2.____(do)the dog have a cat? No, it ____(not).3.____(do)your parents like watching TV? No, they ____(not).4.She ____(not)like listening to music.三、Drills and consolidation 1.第三人称单数的否定句修改

T: Let’s “Do the iron when the water is boiled.”(乘热打铁)用好isn’t, can’t , don’t doesn’t.1.He is a student.(否定句)He isn’t a student.2.I like fishing.(否定句)I don’t like fishing.3.They can swim.(否定句)They can’t swim.4.The dog likes going to the park.(否定句)The dog don’t like„

T: sorry.请看下the dog„

S: 第三人称单数,用doesn’t否定。

Example: Mike goes to school everyday.(否定句)S: Mike doesn’t goes to school everyday.T: doesn’t 已经体现出了第三人称单数的动词变化,因此把动词goes变回原形go就可以了。Mike doesn’t go to school everyday.Example: She watches TV on Saturdays.(否定句)S: She doesn’t watch TV on Saturdays.2.第三人称单数综合练习(小组竞赛)1.____(do)his brother have any hobbies?
