名词的数
名词分为可数名词和不可数名词.
不可数名词的量有两种表示方法：
1） 用some, much, a little, a lot of, a bit of, plenty of 等表示多少.
注意：既可以与可数名词复数,又可以与不可数名词连用的有：plenty of , some, a lot of, lots of , most of等.
2） 用单位词表示.
用a…of表示.
如 a cup of(一杯…), a bottle of(一瓶…)
a piece of(一张...), a pair of(一双...)
a piece of information
a piece of work
a piece of paper
a piece of meat
a piece of news
a cup of water
a bowl of rice
a bag of rice
a glass of beer
a…of后接抽象名词和物质名词(不可数名词)外, 还可接可数名词复数形式.
如 a pair of shoes a bag of nuts a pair of glasses a basket of apples
注意: 单位词后的动词复数形式往往取决于单位词的单复数形式; 千,百等数词与名词连用, 表示复数时, 数词仍保持单数, 名词变复数.
可数名词分为单数和复数.
1. 可数名词单数就是该词本身,在其前面加a或an.
注意：a用于辅音开头的单数名词前；an用于元音开头的单数名词前.
3. 复数
A． 规则变化
1） 一般情况下加-s.
如 book-books desk-desks month-months pen-pens boy-boys girl-girls
2）以s, x, ch, sh结尾加es.
如 box-boxes bus-buses watch-watches brush-brushes class-classes
3）以辅音字母+y结尾,变y为i再加es
如 city-cities country-countries
注意：以元音字母+y结尾,直接加-s
如day-days boy-boys
4) 以f或fe结尾,复数变f或fe为v再加-es.
如 knife-knives half-halves shelf-shelves leaf-leaves wife-wives life-lives
注意：a. 有少数词后直接加-s, 如roof-roofs.
b. 个别两种都可以, 如:handkerchief-handkerchiefs handkerchieves
5)以o结尾.
a．有的加-es.
如 tomato-tomatoes potato-potatoes
b．有的加-s
如 piano-pianos zoo-zoos photo-photos kangaroo-kangaroos kilo-kilos
B． 不规则变化
1） 元音字母发生变化
如man-men woman-women tooth-teeth foot-feet mouse-mice policeman-policemen policewoman-policewomen
2） 词尾发生变化
如 child-children ox-oxen
3） 单复数形式相同
如 fish-fish sheep-sheep deer-deer Chinese-Chinese yuan-yuan jin-jin
Japanese-Japanese
注意：不说an English,要说an Englishman.
4） 形似单数,实为复数意义.
如 people,these people 不说a people 可说a person
police,ten police 不说 a police,可说a policeman
5） 由man和woman构成的合成名词,变复数时将名词及man,woman都变成复数.
如 a man driver- a women driver a woman doctor- a women doctor
6）合成名词变复数时,通常只将里面所含的主体名词变为复数.
如 passer-by---passers-by bus driver-bus drivers
注意；如果没有主体名词,就在最后一词上加-s.
如 grown-up---grown-ups letter-box---lettere-boxes
注意：hair和friut通常作单数,表示总体.若表示若干根头发或若干种水果,则需用这两个词的复数形式.
如 Would you like some more fruit?你要不要再吃点水果?
We bought a lot of fruit from the market. 我们从市场上买了许多水果.
China has some good fruits. 中国有一些好的水果.

She has a few white hairs. 她有好几根白头发.
His black hair is going white. 他的黑发逐渐变成灰白色.
注意：wind, snow和rain这类词,有时也可以有复数形式,表示多次的风,雪,或雨.
以boy,girl开头的复合名词变成复数时,一般只把后一名词变成复数.
如boy student- boy students girlfriend-girlfriends
7）有些名词只用作复数
如scissors,trousers,shorts,jeans,compasses,scales,sunglasses,surroundings, savings,writings,thanks,congratulations,clothes,riches,stairs,greens,brains,goods
注意：形似复数,实际作为单数用的名词有maths,physics,politics,news,the United States等.
8）名词+man（woman）构成的复合名词,其复数形式通常与简单名词一样,即把man （woman）改成men（women）.
如 Englishman-Englishmen Frenchwoman-Frenchwomen
注意：German不是复合词,它的复数是Germans.
一.代词的种类： 人称代词,物主代词,反身代词,指示代词,不定代词,疑问代词,连接代词,关系代词和相互代词.
二.代词的用法
1.人称代词
1）表示你,我,他,她,它,我们,你们,他们的词叫人称代词.
主格
宾格
形容词性物主代词 名词性物主代词 反身代词
I me my mine myself
第一人称单复数 we us our ours ourselves
第二人称
单数 you you your yours yourself
复数 you you your yours yourselves
第三人称
单数 he him his his himself
she her her hers herself
it it its its itself
复数 they them their theirs themselves
人称代词it的特殊用法：一般it指“它”,但在表示天气、时间、距离等时,用it来代替,此时的it并不译为“它”.
当三个人称代词(单数)同时出现时,其先后顺序为you,he,I.而复数一般采用we,you,they顺序.
2．物主代词

词义 单数 复数
类别 我的 你的 他（她,它）的 我们的 你们的 他们的
形容词性 my your his, her, its our your their
名词性 mine yours his, hers, its ours yours theirs
物主代词的用法：
形容词性物主代词后面一定要跟上一个名词, 只作定语,不作表语.
名词性物主代词可作主语、表语、宾语.
3．反身代词
1) 反身代词的构成分两种：第一、二人称反身代词在形容词性物主代词后加上self或selves,第三人称的反身代词在宾格代词后加上self或selves．
2)反身代词的用法：一种是作宾语,由主语发出的动作又回到动作者本身.
如：I enjoyed myself at the party．另一种是作名词或代词的同位语；用来加强语气.如：I can do it myself．
3)初中阶段由反身代词构成的常用词组有：enjoy oneself,help oneself to,learn by oneself,teach oneself,(all)by oneself,leave...by oneself,lose oneself in等,在运用反身代词时,应注意它在数、性别上与哪一个保持一致.试比较：
“Help yourselves to some fish,Tom and Mike．”与I can’t leave the girl by herself．
4. 指示代词
指示代词的常用用法：1）this/ these 通常指空间上和时间上较近的人或物,而that/ those 则指较远的人或物.
指示代词的特殊用法：

(2)this,that有时可代替句子或句子中的一部分.
5. 不定代词
主要不定代词的用法：
(1)one的用法

C.在疑问句中,一般不用some,只有当问句表示一种邀请或者请求,或期待一个肯定的回答时才能用some.

冠词是虚词,本身不能单独使用,也没有词义,它用在名词的前面,帮助指明名词的含义.英语中的冠词有三种,一种是定冠词,另一种是不定冠词,还有一种是零冠词.
1. 不定冠词的用法

生者.

数词的定义：表示数目多少或顺序先后的词叫做数词.其用法相当于名词或者形容词.
数词可以分为两种：
1. 基数词：表示数目多少的数词.比如：one, two, there, four…ninety…one hundred等等.
2. 序数词：表示先后顺序的数词.比如：first, second, third, forth…ninetieth…a hundredth等等.
例如：I have only one pencil. 我仅有一支铅笔.(one 是基数词,表示数量)
This is our first lesson of the new term. 这是我们新学期的第一节课.(first 是序数词,表示顺序)

There are two birds in the tree. 树上有两只鸟.(two是基数词,表示数量)
I am the second child in my family. 我是我们家里的第二个孩子.(second是序数词,表示顺序)

There are twenty new books on the desk.桌子上有20本新书.(twenty是基数词,表示数量)
Today is the twentieth day of May. 今天是五月份的第二十天./今天是五月二十日.即: Today is the 20th, May. (twentieth 是序数词,表示顺序)
