名 词 的 数

  内 容 提 要

  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。物质名词和笼统名词为不可数名词。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,数词与名词在实践运用中要照应。

  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.但假如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→fungi, phenomenon→phenomena,syllabus→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. 假如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义。假如这些词做主语,其谓语须用复数形式。

  8. hair和fruit一般状况下用单数,表示总体。但假如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、不可数名词转自环 球 网 校edu24ol.com

  1. 不可数名词为物质名词和笼统名词,如information, proverty, advice, anger, applause, baggage, cake, chalk, chocolate, cloth(布), bread, damage(损伤), equipment, fruit, furniture, gold, information, ink, jewellery, luggage, mail(邮件), money, news, paper, protection, soap, sugar, weaponry, machinery, scenery, personnel, work等

  注:不可数名词能够与表示量的可数名词连用,借以表示"可数"的概念,我们能够加 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(一条倡议) /a basket of fruit(一篮水果) /an item of information (一则信息)/a kind of protection(一种维护)等。

  2. 有些笼统名词的意思能够转变成为详细名词,这时要用其复数形式

  The insurance company paid $10000 in damages for the accident. ("damage"原本为不可数名词"损伤",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(消灭)――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(办法), rapids(急流),shorts(短裤), sweets(欢乐), valuables (贵重物品)。
