一、可数名词和不可数名词
1)名词的分类

| 抽象名词 | 表示动作、状态、品质、感情等抽象概念 | work, time, news | ||
| 专有名词 | 某个（些）人，地方，机构等专有的名称 | Marx, Shanghai, | ||
2)可数名词
可数名词指可以计数人和事物的名词。
(1)单数和复数
可数名词有单数和复数两种形式。复数形式通常是在单数形式后加词尾“s”构成，其主要变法如下：
1. 一般情况下,在词尾加 —s. .例如maps desks days dogs
2. 以s, x, sh, ch结尾的名词后面加—es class—classes box—boxes brush—brushes watch—watches
3. 以e结尾的名词后面加—s houses
4. 以 —f 或 —fe 结尾的名词,把 —f 或—fe 变成 —ves
bookshelves, wives , knives
5. 以辅音+y 结尾的名词,变 y 为 i, 再加 es，但要注意的是以元音字母加y结尾的名词复数形式只加s如boys days babies factories
6. 以辅音 + o 结尾的名词,加 —es, heroes potatoes tomatoes但词末为两个元音字母的词只加s，radios，photos，zoos等。
7. 以th结尾的名词加-s truth-truths,mouth-mouths, month-months, path-paths
以下是不规则变复数形式
8. 少数名词有不规则的复数形式，
例如： man — men, woman — women, foot — feet, tooth — teeth,mouse — mice, sheep — sheep, dear — dear, fish — fish, child— children. people—people ,Chinese— Chinese. Japanese— Japanese.
注意：其余国家的人的复数都是+s
注意与man和 woman 构成的合成词，其复数形式也是men 和women例如： an Englishman two Englishmen 但注意 Germans, Canadians; man, woman 等作定语时，它的单复数以其所修饰的名词的单复数而定，如：men workers, women teachers.
9. 单数形式但其意为复数的名词有people, police等部分集体名词既可以作单数(整体)也可以作复数(成员)audience, class, family, crowd, group, government,population, team, public
10. 英语中有些名词总是以复数形式出现。scissors 剪刀 goods 货物 trousers 裤子clothes 衣服 glasses 玻璃杯 police 警察 stockings 长裤 socks短袜 boots 靴
11. 复数形式表示特别含义customs (海关) times (时代) drinks(饮料) sands(沙滩) ruins(废墟) papers(文件报纸) fishes(各种鱼)
12. 数词+名词作定语时，这个名词一般保留单数形式，中间加连字符。例如：an 8-year-old girl, a ten-mile walk
13. 合成名词将主体名词变为复数 sons-in-law, lookers-on, passers-by, boy friends 无主体名词时将最后一部分变为复数grown-ups
14. 只有作单数的复数形式的名词：科学名词：physics, maths专有名词：the United States其他名词：news, falls
3)不可数名词
不可数名词指不可以直接计数事物的名词，多为物质名词或抽象名词，不可数名词没有复数形式，不可与a, an连用。在英语中，不可数名词如果要表示“量”的概念，可以用以下两种方法：
1 用much, a little, a lot of, some, any等表示多少，
例如：
The rich man has lots of money.
There is some milk in the cup.
Is there any water in the glass?
2 用a piece of这类定语，
例如：a piece of paper; a piece of wood; a piece ofbread; a glass of water; a cup of tea; 如果要表示“两杯茶”这类概念时，在容器后加复数，two cups of tea; four pieces of paper; three glasses of water
二、祈使句
祈使句用来表示劝告、请求或命令，其主语为第二人称代词you，常被省略，因此祈使句以动词原形开头。为了使语气比较客气，可在句首或句尾加上 please，语调为降调。其否定形式使在动词原形前加 don't。例如：
Please peal three pears.
Let's make fruit salad.
Be quiet, please!
How do you make a banana milkshake?
