小學(xué)名詞單數(shù)變復(fù)數(shù)教案嘔心之作（課堂PPT）

1、12語法是句子結(jié)構(gòu)的基礎(chǔ)，語法是句子結(jié)構(gòu)的基礎(chǔ)，萬丈高樓平地起。萬丈高樓平地起。單詞是一磚一瓦單詞是一磚一瓦而語法則是鏈接這一磚一瓦的水泥而語法則是鏈接這一磚一瓦的水泥 34Whats this?What are these?5Whats this?What are these?6Whats this?What are these?7一：一： 可數(shù)名詞的單復(fù)數(shù)變化規(guī)則可數(shù)名詞的單復(fù)數(shù)變化規(guī)則定義：可數(shù)名詞分為單數(shù)和復(fù)數(shù)。名詞單數(shù)就是該詞本身， 在其前面加“a”或“an”1) 單數(shù)名詞如：a desk(一張桌子)an old desk(一張舊書桌) 8什么時候用什么時候用“a”, 什么時候用什么

2、時候用“an”a用在以輔音音素讀音開頭的單前 an用在以元音音素讀音開頭的單詞前 hat European book useful book apple onion egg hour91: 一般在詞尾加s，如：book-books，bag-bags2: 以s、x、ch、sh結(jié)尾的名詞加es，如: bus-buses, box-boxes, watch-watches, class-classes, sandwich-sandwiches103: 以輔音字母加y結(jié)尾的名詞，變y為i再加es，讀iz； 如：baby babies , boy boysstory-stories, candy-can

3、dies, country-countries區(qū)別： 元音字母+y結(jié)尾的名詞變復(fù)數(shù)時， 直接加“s”變復(fù)數(shù)。 （元音字母有 a e i o u）monkey-monkeys holiday-holidays boy-boys 114. 以o結(jié)尾的名詞加es 的有：Negroes and heroes eat tomatoes and potatoes. 口訣： 黑人和英雄吃土豆和西紅柿其余的以o結(jié)尾的名詞，加s。 如：zoozoos photophotos125. 以f、fe結(jié)尾的名詞變f、fe為ves, 如：wolfwolves wife wives life lives knife kni

4、ves leaf-leaves thief-thieves half-halves shelf-shelves136.單復(fù)同形的名詞有：Chinese Japanese sheep deer fish 注意：fish當(dāng)一條魚講時，單復(fù)數(shù)同形， 如three fish.當(dāng)強調(diào)魚的種類時，要加es. 如：all kindskaindz of fishes .各種各樣的魚 當(dāng)魚肉講時，不可數(shù)。147.名詞復(fù)數(shù)的不規(guī)則變化： manmen woman women toothteeth footfeet goose geese mousemice childchildren 15常見不可數(shù)名詞，不可數(shù)名

5、詞沒有復(fù)數(shù)形式。water(水) milk(牛奶) tea(茶) rice(米飯) orange（橙汁）juice（果汁）bread（面包）不可數(shù)名詞的數(shù)量關(guān)系可借助量詞表示，如。a cup of tea two cups of tea16How many修飾可數(shù)名詞 There are some books on the table?(對劃線部分提問)How many books are there on the table?特殊疑問句：特殊疑問句： 17How many的用法：（1）對there be句型中主語的數(shù)量如:some,five,only one等提問時,如果主語是可數(shù)名詞,不管

6、主語是單數(shù)還是復(fù)數(shù)一般都用復(fù)數(shù)形式提問,因為問話人不知道具體的數(shù)量是多少,而且many只能接可數(shù)名詞復(fù)數(shù)形式,所以be一定要用are.即用How many+可數(shù)名詞復(fù)數(shù)+are there+地點/時間狀語?的句型結(jié)構(gòu).例如:1.There is a book on the desk.(用how many改為特殊疑問句)How many books are there on the desk?規(guī)律總結(jié)：how many用來修飾可數(shù)名詞的復(fù)數(shù),句式： How many+復(fù)數(shù)名詞+一般疑問句?記憶口訣how many在句首,名詞復(fù)數(shù)跟著走,一般問句緊相隨,其它成分不要丟.18How much修飾不可

7、數(shù)名詞 How much rice do you have?How much還有個用法是How many沒有的,就是問價格,例如：How much is the hat?帽子多少錢?19用many,much 填空： 1.How _ is that skirt? 2. How _ people are there in your family? 3. How _ rice do you need? 4. I have _toys in my house. 5. How _ bread is there in the box?201. -What do you eat for your breakfast? - I eat _. A. a egg and some breads B. an egg and some bread C. an egg and some breads2. I want _ apple juice. I
