foot — feet, tooth — teeth

②单复数同形词
deer, sheep, fish, Chinese, Japanese等。
③由名词作定语构成的短语,只在后面的名词后加-s。
如:apple trees苹果树;若是由man/woman作定语修饰名词时,前后都发生变化,如: men teachers, women doctors。
可数名词的特点
1)可数名词有单、复数之分。
例:a bird 一只鸟;many birds 很多只鸟
2)可数名词可以直接用不定冠词a/an、数词或many, some, any, a lot of, lots of等修饰。
例:an apple ;three chairs ; some students
There is a pen on the desk. 桌子上有一支钢笔。
There are many students in the classroom. 教室里有很多学生。
3) 可数名词单数形式作主语时,谓语动词用单数形式;复数形式或两个(或两个以上)单数名词作主语时,谓语动词用复数形式。
4) 在特殊疑问句中,用how many修饰可数名词。
例:How many pens do you have 你有多少支钢笔?
不可数名词的特点
2)不可数名词作主语时,谓语动词用单数形式。
1)不可数名词前可以用much, a little, a lot of等修饰。
例:much bread 很多面包;a little tea 一点儿茶
例:There is some money in the purse. 钱包里有一些钱。
借助表示“张”“片”的单位词piece a piece of paper 一张纸
a piece of bread 一片面包
借助表示容量的词 a bottle of water 一瓶水
a cup of tea 一杯茶
借助表示重量的词 a kilo of meat 一千克肉
借助表示形状的词 a drop of water 一滴水
a bar of chocolate 一条巧克力
3) 不能用不定冠词a/an或数词直接修饰。若要表示数量,则需要借助一定的单位词来表示。
4) 特殊疑问句中,对不可数名词的量提问,用how much。
例:How much milk is there in the glass 玻璃杯中有多少牛奶?
5) 有些名词既可以作可数名词,又可以作不可数名词。但它们的汉语意思有差别。
例: fish 鱼(可数),鱼肉(不可数);
chicken 小鸡(可数),鸡肉(不可数);
glass 玻璃杯(可数),玻璃(不可数)。
知识探究
We’ve got lots of apples.
We haven’t got any oranges.
We haven’t got any meat.
She hasn’t got any coffee.
—Have we got any chocolate
—Yes, we have.
Let’s get some chicken.
We haven’t got any oranges.
have/has got的用法
1. 定义
在英国英语中,常用have/has got来表示“拥有,有”的意思,表示一种所属关系,即“某人拥有……”。在此结构中,have/has是助动词,要随主语发生变化。
如:
He has got a sister and a brother.
We have got some new books.
2. 结构
否定形式
一般疑问句形式
主语 + haven’t/hasn’t got + …
Have/Has + 主语 + got + …
主语 + have/has got + …
肯定形式
have/has got VS there be
结构 相同 不同
have/has got 表示所属关系时,两种结构表示的意思相同,可进行互换。如:
Our school has got a new library.=There is a new library in our school. 表示“某人/某物拥有……”,主语可以是人,也可以是物。
there be 表示“某地有……”,强调的是一种客观存在。
have/has got和there be
some和any
someVS any
相同 不同
some 修饰可数名词和不可数名词。 多用于肯定句。在表示建议、反问、请求的疑问句中,或期望得到肯定回答时,多用some。
any 多用于否定句、疑问句。当any表示“任何”的意义,起强调作用时,可以用在肯定句中。
