新课讲授
Hi! Do you have any money
Of course. I’ll show you some.(当然,我给你看一些).
Let me count(数一数).
One, two, three, four, five moneys.
Oh, no!
money “钱”, 因为没有固定的量化单位（可以是分、角、元、百元、千元等），故称为不可数名词，不能加s。
此处可以表达为：5 yuan。
（注：yuan “元”，凡是用汉语拼音拼出来的词都没有复数形式。）
I want some water.
OK.
Oh, no!
Just a moment(稍等一下).
water “水”, 因为
没有固定的量化单位（可以是一杯、一瓶、一桶、一滴等），
故称为不可数名词，没有复数形式。
I want some bread.
Just a moment(稍等一下).
bread “面包”, 面包的形态不一，量词也不固定。为不可数名词，没有复数形式。
在西方文化中，面包是主食，人们通常不会将其分割成单个单位进行计数。在提及面包时，人们更关注其总量而
非具体数量。
Do you have any roses
Yes. I’ll give you some.
rose “玫瑰”,因为有固定的量化单位（朵），故为可数名词，复数形式直接加s。
一朵玫瑰：a rose
一些玫瑰：some roses
一束玫瑰：
a bunch of roses
（注：加其它量词时，只要数量超过一，都用复数。）
Can you give me a big box for my sheep
Of course I can.
sheep “绵羊”, 可数名词，复数形式为：sheep。
（即：单复数同形）
Thank you.
名词的数：可数名词
不可数名词
（名词是否可数的本质：不是“可不可以去数”，而是看它”是否有一个相对固定的量化单位。）
例如：“钱”、“时间”、“水” ，都没有固定的量化单位，称为不可数名词。
椅子（把）、车（辆）、书（本），有固定的量化单位，称为可数名词。
名词是表示人、事物、地点或抽象概念的词。缩写为n.
例如： baby 婴儿 pencil 铅笔 Shanghai 上海 air 空气
Countable nouns 可数名词

3) 可数名词的用法：

修饰词 可用some/any、many修饰或“数词+(量词)+of”结构来修饰。如：
three apples 三个苹果 three boxes of apples 三箱苹果
主谓一致 如果是单数名词作主语，则谓语动词用单数，如果是复数名词作主语，谓语动词用复数。例如：
The student is/comes from America. 这个学生来自美国。
These students are/come from America.这些学生来自美国。
提问数量 用“How many+可数名词复数.”。例如：
—How many bananas are there 有多少香蕉？
—Three. 三个。(注：不可数名词用How much提问数量。)
思考：怎样区分用a/an来修饰单数可数名词呢？

Summary
拓展：
1. There be与have/has的区别:
There be表示“在某地有某人/某物”；have/has 表示“某人拥有某物”。
但是要注意的是，There have/has 这一表达是错误的。
E.g. I have a bag. There are many pencils in the bag. 我有一个包。包里有很多铅笔。

2. there be句型主语部分有多个名词并列时，be动词要与邻近的主语保持一致，
即就近原则。

There ________ two knives and a box on the table. 桌子上有一个箱子和两把刀。

are
