【重点语法】
名词：名词是表示人、事物、地方、现象及其它抽象概念名称的词。
一、名词分为专有名词和普通名词。
专有名词是表示具体的人、事物、地点、或机构等的专有名称。
如：Guangzhou，Mike，UNESCO等。
专有名词一般情况下第一个字母要大写。
普通名词是表示一类人、事物或抽象概念的名称。
如：police，eggs，rice等。
二、普通名词又可分为个体名词、集体名词、物质名词和抽象名词。
个体名词：表示某一类人或某一类东西中的个体。
如：monkey，panda，ruler，boy等。
集体名词：表示一群人或一类事物的总称。
如：family，police，class，people等。
物质名词：表示无法分为个体或不具备确定形状和大小的实物。
如：Water，air，milk等。
抽象名词：表示抽象概念词。
如：hope，love，spirit。
英语的名词有可数名词和不可数名词两种。
一般来说，个体名词和集体名词多为可数名词，物质名词和抽象名词多为不可数名词。
三、名词单数变复数的规则总结
1. 规则变化
(1)一般在名词词尾加"-s"，
map—maps地图
bird—birds鸟
orange—oranges 桔子
bike—bikes自行车
(2)以s, x, ch, sh结尾的名词加"-es"
box—boxes盒子
class—classes班级
watch—watches手表
dish-dishes盘，碟子，餐具
(3)以o结尾的无生命的名词后面加"-s"
photo—photos相片
radio—radios收音机
zoo—zoos动物园
以o结尾的有生命的名词后面加"-es"
tomato—tomatoes西红柿
potato—potatoes土豆
hero—heroes英雄
negro—negroes黑人
(4)以辅音字母加y结尾的名词，变y为i加"-es "
baby—babies婴儿
family—families家庭
以元音字母加y结尾的名词直接加"-s"
boy—boys男孩
toy—toys 玩具
(5)以fe或f结尾的名词，把fe或f变为v加”-es “
knife—knives小刀
wife—wives妻子
leaf—leaves树叶。
2. 不规则变化
(1)child---children
foot---feet
tooth---teeth
mouse---mice
man---men
woman---women
注意：与 man 和 woman构成的合成词，其复数形式也是 -men 和-women。
如：an Englishman，two Englishmen。
但German不是合成词，故复数形式为Germans。
Bowman是姓，其复数是the Bowmans。
(2)单复同形的名词
如：deer鹿，sheep绵羊，fish鱼，
Chinese中国人，Japanese日本人
li里，jin斤，yuan元
注意：除人民币元、角、分外，美元、英镑、法郎等都有复数形式。如:
a dollar, two dollars; a meter, two meters
(3)集体名词，以单数形式出现，但实为复数。
如：people人， police警察，cattle牛等本身就是复数，不能说 a people，apolice，a cattle.
但可以说 a person，a policeman，a head of cattle
theEnglish，the British，theFrench，the Chinese，the Japanese，the Swiss 等名词，表示国民总称时，作复数用。
如：The Chinese are hard-working and brave.
中国人民是勤劳勇敢的。
3. 以s结尾，仍为单数的名词
(1)maths数学，politics政治(学)，physics物理学等学科名词，为不可数名词，是单数。
(2)news消息、新闻是不可数名词。
(3)the United States美国，the United Nations联合国应视为单数。
The United Nations was organized in 1945. 联合国是1945年组建起来的。
(4)以复数形式出现的书名，剧名，报纸，杂志名，也视为单数。
"The Arabian Nights" is a very interesting story-book.
<<一千零一夜>>是一本非常有趣的故事书。
4. 注意两点
(1)表示由两部分构成的东西，如：glasses (眼镜) trousers, clothes 若表达具体数目，要借助数量词 pair(对，双); suit(套);a pair of glasses; two pairs of trousers
(2)还有一些名词，其复数形式有时可表示特别意思，如：goods货物，waters水域，fishes(各种)鱼
四、不可数名词
不可数名词意味着这些名词只能是单数，没有复数形式，不能与数目字如one, two等连用，也不能加不定冠词a(n)。
不可数名词没有单数、复数之分，但我们在生活中有时候又必需给这些词计量，我们于是采用这种方法：a+表示这些东西的单位+of+不可数名词，
如：acup of tea，a box of milk，apiece of paper等。
如果为了表示多个的概念，我们就将表示这些东西的单位变成复数即可。
如：acup of tea---3 cups of tea，a box of milk---12 boxes ofmilk，A piece of paper---100 pieces of paper
【注意】
a. 当物质名词转化为个体名词时为可数。例如：
Cakeis a kind of food.蛋糕是一种食物(不可数)
Thesecakes are sweet. 这些蛋糕很好吃。(可数)
b. 当物质名词表示该物质的种类时，可数。例如：
Thisfactory produces steel.这个工厂生产钢材。(不可数)
Weneed various steels.我们需要各种各样的钢材。(可数)
c. 当物质名词表示份数时，可数。例如：
Our country is famous for tea. 我国因茶叶而闻名。
Twoteas, please. 请来两杯茶。
d. 抽象名词表示具体的事例时也可数。例如：
fourfreedoms 四大自由
thefour modernizations 四个现代化
