三、Grammar
名词是表示人，事物，地点或抽象概念的名称。名词分为可数名词和不可数名词。可数名词表示可以用数字进行计算的名词，不可数名词表示不能用数字进行计算的。可数名词有单复数形式，若要表示一本书、一只鸟、一棵树等概念，需使用名词的单数形式。表示名词的单数时，要在名词前面加上冠词a或an.若要表示两个或两个以上的概念时，要用到名词的复数形式。
My younger sister has a job in a store.我妹妹在商店工作。
She has two jobs.她打两份工。
（一）、可数名词与不可数名词
注:集体名词做主语时,谓语动词可以用单数,也可以用复数,如果强调整体用单数,强调个体或成员,则用复数.
The police are searching for him.
The Chinese people are brave and hardworking.
（二）、名词复数形式变化：
（1）规则变化
1）一般变化，在名词后加-s，如：book—books; bag—bags
2) 以s, x, ch, sh结尾的名面，加-es，如：bus—buses; box—boxes; watch—watches;
wish—wishes; glass—glasses
3) 以辅音字母加-y结尾的单词，变y为i再加-es，如：city—cities; country—countries;
study—studies; family—families
4) 以f或fe结尾的单词，有些将f或fe变为v, 再加-es; 有些只加-s : wife—wives;
knife—knives; wolf—wolves; thief—thieves; shelf—shelves; myself—myselves;
life—lives; half—halves; leaf—leaves; roof—roofs; chief—chiefs;
belief—beliefs; proof—proofs;
handkerchief—handkerchiefs/handerchieves(手帕／头巾)
记住下面这首顺口溜，相信你就不会觉得难了。
妻子（wife）持刀(knife)去宰狼(wolr)，小偷(thief)吓得发了慌；躲在架后(shelf)保己命(myself)，半(half)片树叶(leaf)遮目光。
按：顺口溜中的红体字是中学阶段学过的九个以—f(e)结尾的名词：wife(妻子)，knife(小刀)，wolf(狼)，thief(小偷)，shelf(架子)，self(自己)，life(生命)，half(一半)，leaf(树
叶)。这九个词变复数时，都是改-f(e)为ve再加-s。由self构成的复合词，其变化
与self相同(如：myself→ourselves；yourself→yourselves；himself，herselfitself→
themselves)。
5) 以o结尾的名词，有些加-s ，有些加-es。如：
hero—heroes; Negro—Negroes; potato—potatoes; tomato—tomatoes (两人
两菜)
photo—photos; radio—radios; piano—pianos; studio—studios;
bamboo—bamboos; zero—zeros/zeroes;
（２）不规则变化
child—children; foot—feet; tooth—teeth; goose—geese; mouse—mice; man—men; woman—women
注意：由一个词加man或woman构成的合成词，其复数形式同上。Englishman—Englishmen; Frenchman—frenchmen; 但German—Germans(不是合成词)
（３）单复数同形deer; sheep; fish; Chinese; Japanese
（４）有些名词只用复数形式：
clothes(衣服); pants(短裤；裤子); jeans(牛仔裤); shorts(短裤); glasses(眼镜); scissors(剪刀)这类词常与a pair of ; two pairs of 这样的短语连用（５）某些词虽以s结尾，但仍为单数；
a. maths, politics, physics等学科名词，一般是不可数名词，为单数；
b.news为不可数名词；
c. the United States(the US); the United Nations(the UN)应视为单数; （三）、不可数名词只有单数形式。
物质名词通常属于不可数名词。如：
液体和气体：water; milk; air; 思想和感觉：beauty; love; hate
极小的物体：rice; salt; sand 学校科目：English; Maths; Art
四、一般现在时中，单数可数名词和不可数名词后要用动词的第三人称单数形式；可数名词复数后要用动词原形。如：
This orange comes from Germany.
This coffee comes from Germany.
These oranges come from Germany.
五、不可数名词的量词
物质名词的数量，一般用单位或容器的量表示，即“单位＋of＋物质名词”
的形式。
I had a bowl of soup and two cups of tea just now.我刚刚喝了一碗汤和两杯茶。
如 a piece of; a bottle of ; a glass of ; two cups of
There be 句型
There be 句型与have（has; had）的各种形式的区别
1、there be 句型表示：在某地有某物（或人）There is a vase on the table.
2、在there be 句型中，主语是单数，be 动词用is ; 主语是复数，be 动词用are ; 如有几件物品，be 动词根据最邻近be 动词的那个名词决定,即“就近一致”。
There is a duck in the pond. There are some ducks in the pond.
There is a ball and some toys on the floor. There are some balls and a toy on the floor.
3、there be 句型的否定句在be 动词后加not , 一般疑问句把be 动词提到句首。在there be句型的般疑问句中，如果可数名词的复数形式和不可数名词前没有别的修饰词，往往都要用any来修饰。
There isn’t s a vase on the table. Is there a vase on the table?
--Is there a post office near here? --Yes, there is .
--Are there any students in the classroom? --No, there aren’t.
Are there any teachers from America in your school?
Is there any rice in your bowl
4、there be句型与have(has) 的区别：there be 表示在某地有某物（或人）；have(has) 表示某人拥有某物。
I have a lot of friends in the classroom.
There are a lot of students in the classroom.
5、some 和any 在there be 句型中的运用:some 用于肯定句,any 用于否定句或疑问句。
There is some water in the glass. There isn’t any water in the glass.
6、and 和or 在there be句型中的运用：and 用于肯定句，or 用于否定句。
There isn’t a pen or two books on the desk.
7、针对数量提问的特殊疑问句的基本结构是：
How many + 名词复数+ are there + 介词短语？
How much + 不可数名词+ is there + 介词短语？
--How many students are there in your school?
--There are about two hundred (students in our school).
8、针对主语提问的特殊疑问句的基本结构是：What’s + 介词短语？
T here is a bird in the tree. →What’s in the tree?
There are some bikes over there. →What’s over there?
There is a little girl in the room. →Who is in the room?
９、There be结构一般用在句子的开头，而have等词只能用于某一个主语后面。
