第二篇：一般現(xiàn)在時(shí)主語第三人稱時(shí)的動(dòng)詞變化

一般現(xiàn)在時(shí)主語第三人稱時(shí)的動(dòng)詞變化

(名詞的復(fù)數(shù)變化規(guī)律)①在一般現(xiàn)在時(shí)中，當(dāng)主語為第三人稱單數(shù)時(shí)，動(dòng)詞要用―s‖型（即第三人稱單數(shù)形式）。②所謂動(dòng)詞―s‖型的構(gòu)成，可按名詞變復(fù)數(shù)的規(guī)則來記，即：

1）在動(dòng)詞尾直接加 s。如：play—plays，want—wants，work—works，know—knows，help—helps，get—gets，reads.2）以字母s、x、ch,sh或o結(jié)尾的動(dòng)詞加-es；如：guess—guesses，fix—fixes，teach—teaches，brush—brushes，go—goes，do—does，watch—watches，catch—catches 3）以輔音字母＋y結(jié)尾的動(dòng)詞，先變y為i，再加-es。如：study—studies，carry—carries，fly—flies，worry—worries 不規(guī)則變化：have----has ③④強(qiáng)調(diào)如何將主語是第三人稱單數(shù)的肯定句變?yōu)榉穸ê鸵蓡柧洹，F(xiàn)舉例說明（用劃線部分來說明順口溜）：

1）His mother works in a factory．>>>>>>>>>>>>>>His mother doesn’t work in a factory． Does his mother work in a factory？

2）Mr Li teaches us English．>>>>>>>>>>>>>Mr Li doesn’t teach us English． Does Mr Li teach you English？

3）My brother studies maths well．>>>>>>>>>>>My brother doesn't study maths well． Does your brother study maths well？ 二．動(dòng)詞ing形式變化小結(jié)：

1、大多數(shù)動(dòng)詞直接在詞尾加-ing，比如：go-going, work-working，study-studying,look-looking,do-doing,eat-eating,play-playing,read-reading,wash-washing,plant-planting,borrow-borrowing,pick-picking,paint-painting,cry-crying,took-tooking(v.拿，占領(lǐng)，接受）climb-climbing

2、有的以不發(fā)音的e字母結(jié)尾的動(dòng)詞，要去掉e再加-ing，比如：make-making, write-writing, skate-skating,close–closing, come-coming, make–making,take-taking，have-having,dance-dancing, smile-smiling,ride-riding,become-becoming, 若結(jié)尾的e 發(fā)音,就不能去掉,如：see-seeing

3、以重讀閉音節(jié)結(jié)尾，末尾只有一個(gè)輔音字母的動(dòng)詞，要雙寫這一輔音字母，再加-ing。如：run-running, swim-swimming,get – getting,sit–sitting,put–putting,begin–beginning,hit-hitting stop-stopping

如果結(jié)尾是元音字母加輔音字母組合,就直接加-ing。比如：drawing, playing

第三篇：名詞、第三人稱單數(shù)

名詞

可數(shù)名詞有單數(shù)和復(fù)數(shù)兩種形式。指一個(gè)人或一件事物時(shí)，用單數(shù)形式；指兩個(gè)或多個(gè)人或事物時(shí)用復(fù)數(shù)形式。名詞由單數(shù)形式變成復(fù)數(shù)形式的規(guī)則如下：

1.一般的名詞詞尾直接加-s。如：

book → books room → rooms house → houses day → days

2.以s, ss, ch, sh, x 結(jié)尾的名詞，在詞尾加-es。如：

bus → buses glass → glasses watch → watches dish → dishes box → boxes

3.以“輔音字母+y”結(jié)尾的名詞，要先將y改為i再加-es。如：

city → cities body → bodies factory → factories等等。

4.以f 或fe 結(jié)尾的名詞，要將f或fe改為v再加-es。如：

half → halves leaf → leaves knife → knives wife → wives

5.特例 [悄悄話：特例常?？迹涀?。]

① child → children ② man → men woman → women

policeman → policemen(規(guī)律：man → men)

③ tomato → tomatoes potato → potatoes

[悄悄話： 初中英語以o 結(jié)尾的名詞變復(fù)數(shù)時(shí)只有這兩個(gè)詞加-es，其余的當(dāng)然加-s嘍！如：photo → photos ]

④ foot → feet tooth → teeth [悄悄話： oo變成ee。]

⑤ sheep, Chinese, Japanese單、復(fù)數(shù)同形 [悄悄話：變復(fù)數(shù)時(shí)詞形不變。]

⑥ people單數(shù)形式表示復(fù)數(shù)意義，要求謂語動(dòng)詞用復(fù)數(shù)； people的復(fù)數(shù)形式peoples通常指“多個(gè)民族”。

不可數(shù)名詞

1.不可數(shù)名詞沒有復(fù)數(shù)，當(dāng)它作句子的主語時(shí)，謂語動(dòng)詞要用單數(shù)形式。如：

The food is very fresh.食品很新鮮。

2.有的不可數(shù)名詞也可以作可數(shù)名詞，有復(fù)數(shù)形式，但他們的意義往往發(fā)生變化。如：

water(水)→ waters(水域)orange(橘汁)→ oranges(橘子)

3.很多的不可數(shù)名詞表示泛指時(shí)為不可數(shù)，表示種類時(shí)就可數(shù)，但意義大多不發(fā)生變化。如：

fruit → fruits food → foods fish → fishes hair → hairs

三、不可數(shù)名詞的數(shù)量表示 不可數(shù)名詞不能與數(shù)詞連用，但若要表示相應(yīng)的數(shù)量，則需要借助一定的單位詞等。如：

1、借助表示“張”、“塊”的單位詞（piece）a piece of paper一張紙 a piece of advice一條建議 a piece of news一條新聞 a piece of chalk 一只粉筆 a piece of bread一塊面包 a piece of work 一項(xiàng)工作 a piece of meat 一塊肉 a piece of ice 一塊冰 a piece of information一條消息 a piece of music 一曲音樂 a piece of wood 一塊木頭 a piece of furniture 一件家具 注意：不要按照漢語習(xí)慣在不該用單位的地方錯(cuò)用單位詞，如“一張郵票”只能說“a stamp”而不能說“a piece of stamp”。

2、借助表示容量的詞 a bottle of ink一瓶墨水 a cup of tea一杯茶 a bowl of rice一碗米飯 a glass of beer一杯啤酒

3、借助表示重量的詞 a kilo of salt一公斤鹽 ten tons of coal十噸煤

4、借助表示形狀的詞 a drop of water一滴水 a grain of sand一粒沙

二、寫出下列名詞的復(fù)數(shù)形式

1.orange_________2.class________3.monkey________4.piano________5.child__________6.shelf_______7.bed_______8.country________9.family_______10.toy________11.foot __12.radio ___13.photo __14.tomato ___15.woman 16.knife ____ 17.sheep 18.ship 19.dish 20.mouse 21.tooth 22.leaf 23.city _______24.zoo_______ 25.tooth_______26.mouse _______ 27.boy______

1.How many________(sheep)are there on the hill?

2.There is some________(food)in the basket.3.The baby has only two________(tooth)now.4.There is a lot of________(water)in the bottle.5.There are five________(people)in his family.6.Let's take________(photo), OK? 7.I have lots of________(tomato)here.8.The________(leaf)on the tree turn-yellow.9.The________(child)are playing games on the playground now.10.Their________(dictionary)look new.11.I see you have a few white________(hair).12.They are________(woman)doctors.13.Can you give me some bottles of ____(orange), please?

動(dòng)詞第三人稱單數(shù)

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：

一、人稱代詞he, she, it是第三人稱單數(shù)。如：

1.He likes cars.他喜歡車。

2.She goes to school at seven.她七點(diǎn)去上學(xué)。3.It has a good name.它有一個(gè)好名字。

二、單個(gè)人名、親朋好友等稱呼作主語 是第三人稱單數(shù)。如：

4、以輔音字母加“y”結(jié)尾的，要先將“y”變?yōu)椤癷”，然后在加“es” 5.特殊變形的有： have-has

四、問句：問句中遇到第三人稱單數(shù)時(shí)，需要用助動(dòng)詞does, 動(dòng)詞變?yōu)樵巍hat does she like? When does he brush his teeth? How often does your sister comb her hair?

練習(xí)

第五篇：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）；
