第一篇:动词原形变第三人称单数的规则 (教师版)
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。
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-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”,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]
be动词包括:am,is,are。第三人称单数用 is;
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?
一般现在时中的第三人称单数形式
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。
I 什么是一般现在时?一般现在时的基本用法有哪些呢?
【No.1】一般现在时的功能
1.表示事物或人物的特征、状态。如:The sky is blue.天空是蓝色的。
2.表示经常性或习惯性的动作。如:I get up at six every day.我每天六点起床。
标志词(时间状语):
always, every week(day, year, month…), once a week,every…, sometimes, at…, on Sunday uauslly often,never,hardly..........3.表示客观现实。如:The earth goes around the sun.地球绕着太阳转。【No.2】一般现在时的构成
1.be动词:主语+be(am,is,are)+其它。如:
I am a boy.我是一个男孩。
2.行为动词:主语+行为动词(+其它)。如:
We study English.我们学习英语。
当主语为第三人称单数(he, she,it)时,要在动词后加“-s”或“-es”。如: Mary likes Chinese.玛丽喜欢汉语。【No.3】一般现在时的变化
1.be动词的变化。
a 否定句:主语+ be + not +其它.如: He is not a worker.他不是工人。
b 一般疑问句:Be +主语+其它。
如:-Are you a student?
-Yes.I am./ No, I'm not.c 特殊疑问句:疑问词+一般疑问句。如: Where is my bike?
2.行为动词的变化。
a 否定句:主语+ don't(doesn't)+动词原形(+其它)。如:
I don't like bread.b 当主语为第三人称单数时,要用doesn't构成否定句。如:
He doesn't often play.c 一般疑问句:Do(Does)+主语+动词原形+其它。如:
-Do you often play football?
Yes, she does./ No, she doesn't.【No.4】特殊疑问句:疑问词+一般疑问句。如: How does your father go to work?
II 哪些主语是第三人称单数? 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。he 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。
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。

动词ing形式的用法及变化规则
一.动词ing形式的用法
1.正在进行时中,谓语动词后加ing.如:I'm playing football.2.一些特殊表达..如: be good at doing sth enjoy doing sth.be busy doing
feel like doing
thank you for doing
do some cooking/cleaning/reading/shopping/washing
go swimming/fishing/shopping/skating/boating
二.动词二.动词现在分词由动词原形在词尾加
ing构成,其规则如下:
1)一般情况下直接加ing think---thinking sleep---sleeping study---studying speak---speaking carry---carrying say---saying
2)以不发音的字母e结尾的单词,去掉字母e,再加ing
wake---waking make---making come---coming take---taking leave---leaving have---having
3)以重读闭音节结尾,呈现“辅,元,辅”结构的动词,先双写末尾的辅音字母,再加ing。初中学过的这类词有:begin,cut, get, hit, run, set, sit, spit, stop, swim, beg, drop, fit, nod, dig, forget, regret, rid, 等。(visit 不是以重读闭音节结尾,不用双写)travel虽然重读第一音节,词尾音节不重读,但是现在分词仍要双写末尾辅音字母,然后再加ing,如:travel---travelling.初中阶段此类词只有这一个。
4)以 y 结尾的动词 直接加 ing
carry—— carrying enjoy—— enjoying
5)以ie结尾的动词,把ie改为y,再加ing
die---dying lie---lying
要特别注意有些动词没有进行时态.1、表示状态、思想、感情和感觉的动词,如:see, hear, love, know, want, hope, think等,没有进行时态。
2、当have/has作为“拥有”时,没有进行时态,但表示“开会,吃饭,玩得高兴”等意思时,可以用进行时表达。
I am having many books.(这是错误的句子)
I am having a good time.(这才是正确的句子)

第五篇:动词第三人称单数
动词第三人称单数
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;do→does 3.以辅音字母+ y 结尾的动词,变y 为i,再+ es,如:study→ studies;try→tries
(a,e,i,o,u是元音字母,其他的21个都是辅音字母)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。
