名词单复数变形规则

名词单复数变形规则

名词单复数变形规则第二部分:不规则变化(10 minutes)我们经常会看到有些名词变复数时并没有遵循上述规则。

这就是名词的不规则变化。

还有一些名词,单复数是同一个形式的。

不过,我们还是可以通过一些比较,发现其中的一些奥妙。

以下我将为大家讲讲名词的不规则变化。

一、有些名词中保存了英语中古旧的复数形式,如:(口头介绍)man-men woman-womentooth-teeth foot-feetchild-children goose-geesemouse-mice ox-oxen二、有些是外来词,仍保有原来的复数形式,如:(黑体部分PPT展示)Phenomenon-phenomena(现象)Formula-formulae(公式)Thesis-theses(论文)Basis-bases(基础)Analysis-analyses(分析)Crisis-crises(危机)Appendix-appendices(附录)Datum-dataBacterium-bacteriaCriterion-criteria(标准)三、部分单词的复数形式不变。

例:fish→fish; sheep→sheep; cattle→cattle; deer→deer; salmon→salmon, means→means四、compound nouns,这类复数词是以主要的名词来表示(PPT展示)(以下5分钟)例:daughter-in-law→daughters-in-law 媳妇; father-in-law→fathers-in-law岳父man-of-war→men-of-war兵舰; maid-servant→maid-servantsstep-son→step-sons继子; son-in-law→sons-in-law; passer-by→passers-by.stand-by →stands-byman-of-war→men-of-war 战舰maid-servant→maid-servants女佣人但是,也有些合成名词,特别是由man和woman构成的合成名词,里面所含的成分,全都要变为复数,如:Man-servant-men-servants,woman doctor-women doctors,men cooks等两个组成部分皆变为复数:* 这种形式的第一个名词必须是man或woman五、有些名词经常是带着-s词尾的,但通常都作单数看待,如:(PPT展示)Phonetics(语音学),physics(物理学),optics(光学),politics(政治),news(新闻)等。

名词的单复数形式及不规则变化

名词的单复数形式及不规则变化

名词的单复数形式及不规则变化名词是我们日常书写和口语表达中最基本的语法成分之一,它们可以用来表示人、物、地点、抽象概念等等。

而名词的单复数形式以及不规则变化则是我们在使用名词时需要了解和熟练掌握的重要知识点。

本文将为您介绍名词的单复数形式及不规则变化,希望对您的学习有所帮助。

1. 名词的一般变化规则大部分名词在构成复数形式时,只需要在词尾加上-s即可。

例如:book(书)→books(书籍),cat(猫)→cats(猫咪),table(桌子)→tables(桌子们)。

此外,以辅音字母+y结尾的名词,将y变为i再加上-es构成复数形式。

例如:baby(宝宝)→babies(宝宝们),lady (女士)→ladies(女士们)。

2. 名词的不规则变化然而,并非所有名词都遵循上述的一般变化规则,一些名词存在不规则的变化方式。

下面列举几种常见的不规则名词变化形式:- 不变复数:一些名词在单数和复数形式上形态完全相同,即复数形式和单数形式相同。

例如:sheep(绵羊),fish(鱼),deer(鹿)。

- 变元复数:一些名词的复数形式与单数形式完全不同。

例如:man (男人)→men(男人们),woman(女人)→women(女人们),child(孩子)→children(孩子们)。

- 变化元音:一些名词在复数形式上变化其元音。

例如:foot(脚)→feet(脚),tooth(牙齿)→teeth(牙齿)。

- 不变单数:一些名词在单数和复数形式上形态完全相同,即复数形式和单数形式相同。

例如:series(系列),species(物种),sheep (羊)。

- 没有复数形式:一些名词没有复数形式,只存在单数形式。

例如:advice(建议),information(信息),furniture(家具)。

需要注意的是,虽然存在不规则变化形式,但英语中大部分名词的复数形式还是遵循一般变化规则的。

综上所述,名词的单复数形式以及不规则变化是英语学习中的基础内容之一。
