英文中的不可数名词与可数名词
1.不可数名词
Some nouns in English are uncountable nouns.
英语中有些单词是不可数名词。
We do not use uncountable nouns in the plural and we do not use them with
the indefinite article, a/an.
不可数名词没有复数形式，我们也不用不定冠词a/an修饰他们。
We ate a lot of foods > We ate a lot of food
We bought some new furnitures> We bought some new furniture.
That’s a useful information > That’s useful information
We can use some quantifiers with uncountable nouns:

He gave me some useful advice.
They gave us a lot of information.

Count nouns have two forms: singular and plural.
可数名词有两种形式：单数和复数。
The singular form refers to one person or thing:
单数形式指一个人或一件物品。
a book; a teacher; a wish; an idea
The plural form refers to more than one person or thing:
复数形式指多于一个人或一件物品：
books; teachers; wishes; ideas
Singular count nouns
单数可数名词
Singular count nouns cannot be used alone. They must have a determiner: 单数可数名词不能单独用。他们必须有一个限定词：
the book; that English teacher; a wish; my latest idea
or a quantifier:
一个量词：
some new books; a few teachers; lots of good ideas
or a numeral:
一个数词：
two new books; three wishes
Plural forms:
复数形式：
We usually add –s to make a plural noun:
我们通常在单数名词后加–s：
book > books; school > schools; friend > friends
We add -es to nouns ending in –ss; -ch; -s; -sh; -x
在以–ss; -ch; -s; -sh; -x结尾的单词后加-es：
class > classes; watch > watches; gas > gases; wish > wishes; box > boxes
When a noun ends in a consonant and -y we make the plural in -ies...
在以一个辅音跟-y结尾的单词后我们加-ies变为复数。
lady > ladies; country > countries; party > parties
…but if a noun ends in a vowel and -y we simply add -s:
但是如果一个单词以元音跟-y结尾的单词，我们直接在单词后面加-s。
boy > boys; day > days; play > plays
Some common nouns have irregular plurals:
一些普通的单词有不规则复数形式：
Man > men; woman > women; child > children; foot > feet;
person > people
Plural count nouns do not have a determiner when they refer to people or things as a group: 当复数可数名词指代一类人或一类事物时，不需要限定词。
