第一篇:動(dòng)詞第三人稱單數(shù)
動(dòng)詞第三人稱單數(shù)
動(dòng)詞,在英語眾多詞匯中堪稱變臉的高手,遇到不同的人稱、數(shù)和時(shí)態(tài),它總會(huì)以不同的面孔登場(chǎng)。本期將重點(diǎn)向同學(xué)們介紹在一般現(xiàn)在時(shí)的句子中,當(dāng)主語是第三人稱單數(shù)時(shí),英語動(dòng)詞的變化規(guī)則。
一般現(xiàn)在時(shí)的肯定句中,主語為第三人稱單數(shù)的動(dòng)詞變化主要體現(xiàn)在詞尾的變化上,其規(guī)律大體有三點(diǎn):
1.一般情況下,直接在動(dòng)詞詞尾+s,例如:get→gets;take→takes 2.以s, sh, ch, x, o 結(jié)尾的動(dòng)詞,在詞尾+ es,例如: teach→ teaches;fix→fixes;go→goes;do→does 3.以輔音字母+ y 結(jié)尾的動(dòng)詞,變y 為i,再+ es,如:study→ studies;try→tries
(a,e,i,o,u是元音字母,其他的21個(gè)都是輔音字母)除上述規(guī)律外,還應(yīng)注意下面三點(diǎn):
1.動(dòng)詞 have,遇到主語是第三人稱單數(shù)時(shí),要用 has; 動(dòng)詞 be 的第三人稱單數(shù)形式是is。
2.含有動(dòng)詞第三人稱單數(shù)形式的句子變否定句時(shí),要用 doesn't + 動(dòng)詞原形,如:
He goes to school at six in the morning.(變否定句)→ He doesn't go to school at six in the morning.3.對(duì)含有動(dòng)詞第三人稱單數(shù)形式的句子提問時(shí),要用助動(dòng)詞 does,如: She goes home at five every day.(對(duì)劃線部分提問)→ When / What time does she go home every day? 綜上所述,只要我們洞悉了英語動(dòng)詞第三人稱單數(shù)形式的變化規(guī)則,在一般現(xiàn)在時(shí)的句子中,我們都能從容應(yīng)對(duì),客隨主“變”了。
第二篇:動(dòng)詞第三人稱單數(shù)
動(dòng)詞第三人稱單數(shù)
一、動(dòng)詞第三人稱單數(shù)的變化規(guī)則及發(fā)音規(guī)律
動(dòng)詞原形變第三人稱單數(shù)的規(guī)則與發(fā)音規(guī)律同名詞單數(shù)變復(fù)數(shù)大致相同,請(qǐng)認(rèn)真觀察。
1、大多數(shù)動(dòng)詞在詞尾加“S”在清輔音后發(fā)音為[s],在濁輔音及元音后發(fā)音為 [z]。如:
①stop-stops [s];make-makes [s] ②read-reads [z];play-plays [z]
2、以輔音字母加“y”結(jié)尾的,要先將“y”變?yōu)椤癷”,然后在加“es”讀[iz] 如: fly-flies [z]; carry-carries [z] study-studies [z];worry-worries
3、以“s, x, ch, sh”結(jié)尾的,在詞尾加“es”,發(fā)音為[iz] 如: teach-teaches [iz];watch-watches [iz]
4、以“o”結(jié)尾的動(dòng)詞,加“es”,讀[z] 如: go-goes [z] do-does [z]
下面幾個(gè)動(dòng)詞變?yōu)閱螖?shù)時(shí),原詞的元音部分的發(fā)音發(fā)生了較大的變化,請(qǐng)注意記憶。如:
1、do [du:]-does [dz]
2、say [sei]-says [sez]
以不發(fā)音字母“e”結(jié)尾的開音節(jié)詞,如果尾音是[s],[z]時(shí),加“s”后字母“e”發(fā)音,與所加“s”
一起讀做[iz]。如: close-closes [iz]
名詞變復(fù)數(shù)規(guī)則
1.一般名詞復(fù)數(shù)是在名詞后面加上“s”,如map→maps,bag→bags等;
2.以s,sh,ch,x等結(jié)尾的詞加“es”,如bus→buses,watch→watches等;
3.以輔音字母+y結(jié)尾的詞,變y為i加es,如baby→babies等;以元音字母+ y結(jié)尾的名詞變復(fù)數(shù)時(shí),直接加s變復(fù)數(shù),如monkey→monkeys,holiday→holidays,storey→storeys(樓層);
4.以o 結(jié)尾的名詞變復(fù)數(shù)時(shí):
a)加s的名詞有:photo→photos,piano→pianos,radio→radios,zoo→zoos
b)加es的名詞有:
potato→potatoes tomato→tomatoes
5.以f或fe結(jié)尾的名詞變復(fù)數(shù)時(shí):
a)加s的名詞有:
belief→beliefs roof→roofs
safe→safes gulf→gulfs
b)去掉f,fe 加ves的名詞有:
half→halves knife→knives
leaf→leaves wolf→wolves
wife→wives life→lives thief→thieves
第三篇:動(dòng)詞第三人稱單數(shù)規(guī)則
第三人稱單數(shù)
第三人稱單數(shù)是英語中的一種語法,也稱“三單”或“單三”,用于一般現(xiàn)在時(shí)的句子,當(dāng)動(dòng)詞在第三人稱單數(shù)后時(shí)【she、he、it、不可數(shù)名詞和人名(一個(gè)人的)】,要根據(jù)其情況變化。
變化規(guī)則情況
方法
示例
一般情況
+s
play—plays
stay--stays 以s、x、ch、sh和o結(jié)尾
+es
go—goes
以輔音字母加y結(jié)尾
變y為i +es
study—studies fly--flies 以f或者fe結(jié)尾
變f或fe為v+es
life—lives
特殊情況
不規(guī)則 have—has 用法
首先,咱們要搞清楚第一、第二、第三人稱各是什么。第一人稱就是“我”和“我們”。第二人稱是“你”和“你們”。
第三人稱單數(shù)是“他”、“她”和“它”,復(fù)數(shù)則是“他們”。
1、中文大多數(shù)實(shí)義動(dòng)詞在詞尾加“s”在清輔音后發(fā)音為/ s /在濁輔音及元音因素后發(fā)音為 / z /。如speak→speaks /s/ come→comes /z/ play→plays /z/
2、以輔音字母加“y”結(jié)尾的動(dòng)詞?要先將“y”變?yōu)椤癷”然后再加“es”讀/z/。如study→studies /z/ fly→flies /z/
3、以“s x ch sh”結(jié)尾的動(dòng)詞在詞尾加“es”發(fā)音為/ iz /。如teach→teaches /iz/;watch→watches /iz/
4、以“o”結(jié)尾的動(dòng)詞,在詞尾加“es”。常出現(xiàn)的兩個(gè)以“o”結(jié)尾的動(dòng)詞go和do后加“es”?讀/z/。如?go→goes /z/ do→does /z/
5、記住最為特別的be的三單is,have的三單是has。
[注意]
1下面兩個(gè)動(dòng)詞變?nèi)龁螘r(shí)原詞的元音部分的發(fā)音發(fā)生了較大的變化 要記憶。
如do/du:/ →does/d z/ say/sei/ → says /sez/
2以不發(fā)音字母“e”結(jié)尾的開音節(jié)詞如果尾音是[s][z]時(shí)加“s”后字母“e”發(fā)音 與所加“s” 一起讀做[iz]。如 close?closes [iz] 中第三人稱單數(shù)的三個(gè)“他”寫法不一樣,讀音卻相同。但在英語中,三個(gè)“他”既有不同的讀音,也有不同的寫法,分別是he, she, it。在第三人稱后不能使用動(dòng)詞的原形,而要在相應(yīng)的動(dòng)詞后加s或es。
簡(jiǎn)單地講,一個(gè)人就是單數(shù),多于一個(gè)人就是復(fù)數(shù)。在咱們漢語里,第三人稱復(fù)數(shù)也就是常說的“他們”或者“她們”,英語中就是they.而“第三人稱單數(shù)”就是指的“他”或者“她”,在英語中,相對(duì)應(yīng)的就是he或者she 句子舉例: 第三人稱單數(shù): He is a student.(他是學(xué)生)
第三人稱復(fù)數(shù): They are students.(他們是學(xué)生)
以上只是一種幫助你理解的簡(jiǎn)單回答,第三人稱還包括一些其他的方面,比如“it”等,這里就不多說了,希望你在學(xué)習(xí)中多多體會(huì)。
在一般現(xiàn)在時(shí)中,當(dāng)主語是第三人稱單數(shù)時(shí),謂語動(dòng)詞要用第三人稱單數(shù)形式,即常在動(dòng)詞原形后加-s或-es。
下面我們歸納一下第三人稱單數(shù)的用法:
一、人稱代詞he, she, it是第三人稱單數(shù)。如:
He likes watching TV.他喜歡看電視。
She has lunch at twelve.她十二點(diǎn)吃午餐。
It looks like a cat.它看起來像只貓。
二、單個(gè)人名、地名或稱呼作主語;是第三人稱單數(shù)。如:
①Han Mei looks like her mother.韓梅看起來像她的母親。
②Beijing is in China.北京在中國(guó)。
③Uncle Wang often makes cakes.王叔叔經(jīng)常做蛋糕。
三、單數(shù)可數(shù)名詞或“this/that/the+單數(shù)可數(shù)名詞”作主語時(shí),是第三人稱單數(shù)。如:
①A horse is a useful animal.馬是有用的動(dòng)物。
②This book is yours.這本書是你的。
③That car is red.那輛小汽車是紅色的。
④The cat is Lucy's.這只貓是露茜的。
四、不定代詞someone, somebody, nobody, everything, something等及指示代詞this, that作主語時(shí),是第三人稱單數(shù)。如:
①Everyone is here.大家到齊了。
②There is something wrong with the watch.這塊手表有毛病。
③This is a pen.這是一支鋼筆。
④That is an eraser.那是一塊橡皮擦。
五、不可數(shù)名詞作主語時(shí)為第三人稱單數(shù)。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、當(dāng)數(shù)字或字母作主語時(shí),看作第三人稱單數(shù)。如:
①
“I” is a letter.“I”是個(gè)字母。
動(dòng)詞第三人稱單數(shù)規(guī)則
動(dòng)詞原形變第三人稱單數(shù)的規(guī)則與發(fā)音規(guī)律同名詞單數(shù)變復(fù)數(shù)大致相同。
1、大多數(shù)動(dòng)詞在詞尾加“S”在清輔音后發(fā)音為[s],在濁輔音及元音后發(fā)音為 [z]。如:
①stop-stops [s] make-makes [s]
②read-reads [z] play-plays [z]
2、以輔音字母加“y”結(jié)尾的,要先將“y”變?yōu)椤癷”,然后在加“es”讀[iz] 如:
fly-flies [z]; carry-carries [z]
study-studies [z];worry-worries
3、以“s, x, ch, sh”結(jié)尾的,在詞尾加“es”,發(fā)音為[iz] 如:
teach-teaches [iz];watch-watches [iz]
4、以“o”結(jié)尾的動(dòng)詞,加“es”,讀[z] 如:
go-goes [z] do-does [z]
下面幾個(gè)動(dòng)詞變?yōu)閱螖?shù)時(shí),原詞的元音部分的發(fā)音發(fā)生了較大的變化,請(qǐng)注意記憶。如:
1、do [du:]-does [dz]
2、say [sei]-says [sez]
以不發(fā)音字母“e”結(jié)尾的開音節(jié)詞,如果尾音是[s],[z]時(shí),加“s”后字母“e”發(fā)音,與所加“s”
一起讀做[iz]。如: close-closes [iz]
be動(dòng)詞包括:am,is,are。第三人稱單數(shù)用 is;過去式為 was;復(fù)數(shù)用are,過去式為were.

大家都知道,在一般現(xiàn)在時(shí)中,當(dāng)主語是第三人稱單數(shù)時(shí),謂語動(dòng)詞要用第三人稱單數(shù)形式,即常在動(dòng)詞原形后加-s或-es。但有些同學(xué)們對(duì)于哪些主語是第三人稱單數(shù)還不十分清楚,現(xiàn)歸納總結(jié)如下:
