Noun Number: Singular and Plural

In English grammar, nouns can be classified into two categories based on their number: singular and plural. The number of a noun refers to whether it is singular (referring to one person, place, thing, or idea) or plural (referring to more than one).

To form the plural of most nouns, we add -s to the end of the singular noun. For example, "dog" becomes "dogs," "cat" becomes "cats," and "book" becomes "books." However, there are some exceptions to this rule.

One exception is when a noun ends in -s, -ss, -sh, -ch, -x, or -z. In these cases, we add -es to form the plural. For example, "bus" becomes "buses," "dress" becomes "dresses," "dish" becomes "dishes," "church" becomes "churches," "box" becomes "boxes," and "buzz" becomes "buzzes."

Another exception is when a noun ends in -y and the letter before the -y is a consonant. In this case, we change the -y to -ies to form the plural. For example, "baby" becomes "babies," "city" becomes "cities," and "berry" becomes "berries." However, if the letter before the -y is a vowel, we simply add -s to form the plural. For example, "toy" becomes "toys" and "key" becomes "keys."

There are also irregular nouns that do not follow any specific rule. For example, "man" becomes "men," "woman" becomes "women," "child" becomes "children," and "tooth" becomes "teeth."

It is important to remember the correct plural form of nouns when writing or speaking in English. Using the wrong form can lead to confusion or misunderstandings. Practice identifying and forming the plural of nouns to improve your English grammar skills.

Countable and Uncountable Nouns

In English grammar, nouns can be further classified into countable and uncountable nouns. Countable nouns refer to things that can be counted, such as "book," "chair," or "dog." We can use numbers or quantifiers like "a," "an," or "some" with countable nouns. For example, "I have three books," "She has an apple," or "They bought some chairs."

Uncountable nouns, on the other hand, refer to things that cannot be counted or have no plural form. These nouns are usually substances, materials, or abstract concepts. Examples of uncountable nouns include "water," "rice," "information," or "love." We cannot use numbers or quantifiers with uncountable nouns. Instead, we use words like "some," "a lot of," or "a little bit of" to express the quantity. For example, "He drank some water," "They cooked a lot of rice," or "She gave me a little bit of information."

Some nouns can be both countable and uncountable, depending on the context. For example, "paper" can be countable when referring to individual sheets of paper, or uncountable when referring to the material itself.

It is important to note that countable nouns can have singular and plural forms, while uncountable nouns only have singular forms. Countable nouns follow the rules mentioned in the first article, while uncountable nouns do not change their form.

Understanding the difference between countable and uncountable nouns is crucial for using the correct grammar and sentence structure. Practice identifying and categorizing nouns to improve your English language skills.

英语语法练习 名词的数

　　名词分为专有名词和普通名词两大类。普通名词又分为个体名词和集体名词。在句子中可数名词要么前边加冠词，要么用其复数形式。名词的复数通常加s，但以s，x，ch，sh结尾的词es；以"辅音字母＋y"结尾的词把"y"变成"i"，再加es。不规则名词的复数有其特殊形式。物质名词和抽象名词为不可数名词。名词有主格(作主语)、宾格(作宾语)和属格(表示所属关系)。冠词分为不定冠词和定冠词，它们有其基本用法和特殊用法。数词分为基数词、序数词和分数词，数词与名词在实际运用中要呼应。

　　第一节 名 词 的 数

　　一、可数名词

　　1. 可数名词有单复数之分。在句中，名词的单数形式前边要有冠词或表示单数的限定词，否则就要用其复数形式。名词的复数形式通常是在单数形式后加词尾s、es，或将y改为i再加es。但如果名词前边有表示单数的冠词或表示单数的限定词，就不能用其复数形式

　　2. 有少数名词的复数形式是不规则的，child→children, man→men, woman→women, foot→feet, tooth→teeth, goose→geese, mouse→mice, ox→oxen

　　3. 英语里还有些名词的单复数变化较为特殊，需特别注意

　　analysis→analyses, bacterium→bacteria, basis→bases, crisis→crises, criterion→criteria, datum→data, formula→formulae(或formulas), fungus真菌→fungi, phenomenon→phenomena,syllabus讲义等的)摘要, 提纲; 课程提纲, 教程提纲→syllabi, thesis→theses

　　4. 有些名词的单复数是一样的：aircraft, spacecraft, Chinese, deer, fish, Japanese, means, series, species等。

　　5. 如果前边有表示复数的限定词时名词用其复数形式

　　6. 在形容词最高级中，表示范围的of后要用名词复数形式

　　7. 有些集体名词在形式上是单数如people(人民，人们)，police(警察)，cattle(牲畜)，staff(全体人员，全体职员)，但它们表达复数的含意。如果这些词做主语，其谓语须用复数形式。

　　8. hair和fruit一般情况下用单数，表示总体。但如果我们要表示若干根头发或几种水果时，就要用这两个词的复数形式

　　eg: He bought apples, oranges and other fruits. ("fruits"在此处意为"多种水果")

　　另外还要注意：police和cattle的谓语形式总是用复数形式。

　　9. 名词做定语时，不能用作复数

　　二、不可数名词

　　1. 不可数名词为物质名词和抽象名词，如information, proverty, advice, anger, applause, b

　　注：不可数名词可以与表示量的可数名词连用，借以表示"可数"的概念，我们可以加 a(n) piece ［sheet(张), suit(套), tube(管), packet(包), item(条，则), bar(条), basket(篮子), glass(杯),bunch(束), pair(双，对), bowl(碗), portion(份), herd(群), series(系列), shower(阵) etc. ］，如：a piece of advice(一条建议) ／a basket of fruit(一篮水果) ／an item of information (一则信息)／a kind of protection(一种保护)等。

　　2. 有些抽象名词的意思可以转变成为具体名词，这时要用其复数形式

　　The insurance company paid $10000 in damages for the accident. ("damage"本来为不可数名词"损害"，变复数后意思是"损失赔偿费"。)

　　单复数含义不同的名词还有：communication(通讯)--communications(通讯系统，通讯工具)；cloth(布)--clothes(衣服)；content(内容)--contents(目录)；convenience(便利)--conveniences(便利设备)；humanity(人类)--humanities(人文科学)；necessity(需要)--necessities(必需品)；pain(疼痛)--pains(辛劳)；ruin(毁灭)--ruins(废墟，遗迹)；sand(沙子)--sands(沙地，沙滩)；wood(木材)--woods(树林)；work(工作)--works(工厂，著作)。

　　另外，有些名词通常只用复数形式，如：fundamentals(基本原则)，goods(货物), means(方法), rapids(急流)，shorts(短裤), sweets(欢乐), valuables (贵重物品)。
