課 題 第三人稱單數(shù) 教學(xué)目標(biāo) 掌握第三人稱的用法 重點(diǎn)、難點(diǎn) 什么叫第三人稱單數(shù)、第三人稱單數(shù)的變化規(guī)律 考點(diǎn)及考試要求 什么叫第三人稱單數(shù)、第三人稱單數(shù)的變化規(guī)律 教學(xué)內(nèi)容 哪些主語(yǔ)屬于第三人稱單數(shù)哪些主語(yǔ)屬于第三人稱單數(shù)哪些主語(yǔ)屬于第三人稱單數(shù)哪些主語(yǔ)屬于第三人稱單數(shù)? 一般現(xiàn)在時(shí)中,當(dāng)主語(yǔ)是第三人稱單數(shù)時(shí),謂語(yǔ)動(dòng)詞要用第三人稱單數(shù)形式。其實(shí)主語(yǔ)是第三人稱單數(shù),主要有以下幾種情況: 1.不可數(shù)名詞作主語(yǔ)。 如: Some water is in the glass. 水在玻璃杯里。 2.單個(gè)的可數(shù)名詞作主語(yǔ)。 如:The girl is American. 這個(gè)女孩是美國(guó)人。 My watch is on the dresser. 我的手表在梳妝臺(tái)上。 3. he, she, it等代詞單獨(dú)作主語(yǔ)。如: He is in the tree. 他在樹上。 She likes her family very much. 她非常喜歡她的家。 4.單個(gè)的人名、地名或稱呼作主語(yǔ)。 如:Tony is a doctor. 托尼是一位醫(yī)生。 Uncle Li speaks a little English. 李叔叔會(huì)說一點(diǎn)兒英語(yǔ)。 Gaocheng is a beautiful town. 藁城是一座美麗的城鎮(zhèn)。 5. 指示代詞this, that等作主語(yǔ)。 如:This is a pear. That is an apple. 這是一個(gè)梨,那是一個(gè)蘋果。 6. everyone, everything, something nobody nothing 等不定代詞作主語(yǔ)時(shí)。 如: Is everyone here today? 今天大家都到齊了嗎? Nobody can answer the question. 沒有人能回答出這個(gè)問題。 7. 單個(gè)數(shù)字作主語(yǔ)時(shí)。 如: “8” is a good number in China. 在中國(guó)8是個(gè)好數(shù)字。 詞尾變化規(guī)則: 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 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 除上述規(guī)律外除上述規(guī)律外除上述規(guī)律外除上述規(guī)律外,還應(yīng)注意下面三點(diǎn)還應(yīng)注意下面三點(diǎn)還應(yīng)注意下面三點(diǎn)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 doesnt + 動(dòng)詞原形, He goes to school at six in the morning. (否)→ He doesnt 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(yǔ)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。 【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] 但有些同學(xué)們對(duì)于哪些主語(yǔ)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: 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(yǔ);是第三人稱單數(shù)。如: ①Han Mei looks like her m 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(yǔ)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 Lucys. 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(yǔ)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(yǔ)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(yǔ)時(shí),看作第三人稱單數(shù)。如:①"6" is a lucky number. "6"是個(gè)吉利數(shù)字。 ②"I" is a letter. "I"是個(gè)字母 三、家庭作業(yè) 一、 寫出下列動(dòng)詞的第三人稱單數(shù) drink ________go _______ stay _______ make ________ look ________ have_______ pass_______ carry ________ come_______ watch______ plant_______ fly ________ study_______ brush________ do________ teach_______ 二、用括號(hào)內(nèi)動(dòng)詞的適當(dāng)形式填空。 1.
