12语法是句子结构的基础，语法是句子结构的基础，万丈高楼平地起。万丈高楼平地起。单词是一砖一瓦单词是一砖一瓦而语法则是链接这一砖一瓦的水泥而语法则是链接这一砖一瓦的水泥 34Whats this?What are these?5Whats this?What are these?6Whats this?What are these?7一：一：可数名词的单复数变化规则可数名词的单复数变化规则定义：可数名词分为单数和复数。名词单数就是该词本身，在其前面加“a”或“an”1)单数名词如：a desk(一张桌子)an old desk(一张旧书桌)8什么时候用什么时候用“a”,什么时候用什么时候用“an”a用在以辅音音素读音开头的单前 an用在以元音音素读音开头的单词前 hat European book useful book apple onion egg hour91:一般在词尾加s，如：book-books，bag-bags2:以s、x、ch、sh结尾的名词加es，如:bus-buses,box-boxes,watch-watches,class-classes,sandwich-sandwiches103:以辅音字母加y结尾的名词，变y为i再加es，读iz；如：baby babies,boy boysstory-stories,candy-candies,country-countries区别：元音字母+y结尾的名词变复数时，直接加“s”变复数。（元音字母有 a e i o u）monkey-monkeys holiday-holidays boy-boys 114.以o结尾的名词加es 的有：Negroes and heroes eat tomatoes and potatoes.口诀：黑人和英雄吃土豆和西红柿其余的以o结尾的名词，加s。如：zoozoos photophotos125.以f、fe结尾的名词变f、fe为ves,如：wolfwolves wife wives life lives knife knives leaf-leaves thief-thieves half-halves shelf-shelves136.单复同形的名词有：Chinese Japanese sheep deer fish 注意：fish当一条鱼讲时，单复数同形，如three fish.当强调鱼的种类时，要加es.如：all kindskaindz of fishes.各种各样的鱼 当鱼肉讲时，不可数。147.名词复数的不规则变化：manmen woman women toothteeth footfeet goose geese mousemice childchildren 15常见不可数名词，不可数名词没有复数形式。water(水)milk(牛奶)tea(茶)rice(米饭)orange（橙汁）juice（果汁）bread（面包）不可数名词的数量关系可借助量词表示，如。a cup of tea two cups of tea16How many修饰可数名词 There are some books on the table?(对划线部分提问)How many books are there on the table?特殊疑问句：特殊疑问句：17How many的用法：（1）对there be句型中主语的数量如:some,five,only one等提问时,如果主语是可数名词,不管主语是单数还是复数一般都用复数形式提问,因为问话人不知道具体的数量是多少,而且many只能接可数名词复数形式,所以be一定要用are.即用How many+可数名词复数+are there+地点/时间状语?的句型结构.例如:1.There is a book on the desk.(用how many改为特殊疑问句)How many books are there on the desk?规律总结：how many用来修饰可数名词的复数,句式：How many+复数名词+一般疑问句?记忆口诀how many在句首,名词复数跟着走,一般问句紧相随,其它成分不要丢.18How much修饰不可数名词 How much rice do you have?How much还有个用法是How many没有的,就是问价格,例如：How much is the hat?帽子多少钱?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 feel very thirsty.A.a B.a glass of C.a pair of3.How many _ can I take?A.orange B.oranges C.apple21Thank you!
