第一篇:動(dòng)詞原形變第三人稱(chēng)單數(shù)的規(guī)則 (教師版)
動(dòng)詞原形變第三人稱(chēng)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(kāi)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(chēng)單數(shù)用 is;
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(yǔ)是第三人稱(chēng)單數(shù)時(shí),要用 has; 動(dòng)詞 be 的第三人稱(chēng)單數(shù)形式是is。
2.含有動(dòng)詞第三人稱(chēng)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(chēng)單數(shù)形式的句子提問(wèn)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(wèn))→ When / What time does she go home every day?
一般現(xiàn)在時(shí)中的第三人稱(chēng)單數(shù)形式
在一般現(xiàn)在時(shí)中,當(dāng)主語(yǔ)是第三人稱(chēng)單數(shù)時(shí),謂語(yǔ)動(dòng)詞要用第三人稱(chēng)單數(shù)形式,即常在動(dòng)詞原形后加-s或-es。
I 什么是一般現(xiàn)在時(shí)?一般現(xiàn)在時(shí)的基本用法有哪些呢?
【No.1】一般現(xiàn)在時(shí)的功能

1.be動(dòng)詞的變化。
a 否定句:主語(yǔ)+ be + not +其它.如: He is not a worker.他不是工人。

如:-Are you a student?
-Yes.I am./ No, I'm not.c 特殊疑問(wèn)句:疑問(wèn)詞+一般疑問(wèn)句。如: Where is my bike?
2.行為動(dòng)詞的變化。
a 否定句:主語(yǔ)+ don't(doesn't)+動(dòng)詞原形(+其它)。如:

第五篇:動(dòng)詞第三人稱(chēng)單數(shù)
動(dòng)詞第三人稱(chēng)單數(shù)
動(dòng)詞,在英語(yǔ)眾多詞匯中堪稱(chēng)變臉的高手,遇到不同的人稱(chēng)、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(yǔ)是第三人稱(chēng)單數(shù)時(shí),英語(yǔ)動(dòng)詞的變化規(guī)則。
一般現(xiàn)在時(shí)的肯定句中,主語(yǔ)為第三人稱(chēng)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(yǔ)是第三人稱(chēng)單數(shù)時(shí),要用 has; 動(dòng)詞 be 的第三人稱(chēng)單數(shù)形式是is。
2.含有動(dòng)詞第三人稱(chēng)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(chēng)單數(shù)形式的句子提問(wèn)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(wèn))→ When / What time does she go home every day? 綜上所述,只要我們洞悉了英語(yǔ)動(dòng)詞第三人稱(chēng)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。
