知识要点

一、名词的数

在英语中，名词按其所表示的事物的性质可分为可数名词和不可数名词。可数名词有单数和复数两种形式。单数名词表示一个可数事物。复数名词表示两个或两个以上的可数事物。可数名词可分为单数和复数两种形式：表示一个人或事物的名词用单数形式，在使用时，前面一般加不定冠词a或an，表示两个或两个以上的人或事物的名词用复数形式,一般是在词干后附加词尾s 或es,如：bags ,boxes.名词单数变复数具体规则如下：

1).规则变化

①一般在名词后加s.如boy→boys, pen→pens等。

②以s, x, sh, ch结尾的，在后面加es.如class→classes,但stomach的复数为stomachs.

③"以辅音字母+y"结尾的，y变为i，然后再加es.如baby→babies.

④以f或fe结尾的名词把f或fe改为v, 再加es. 如knife, half, leaf, wolf等。

⑤以o结尾的名词，除tomato, potato等少数在后面加es外，一般是在后面直接加s.如kilo→kilos, photo→photos, zoo→zoos, radio→radios, piano→pianos, video→videos.

2).不规则变化

① man→men, woman→women, foot→feet, tooth→teeth,，child-children，mouse→mice

② 单复数形式相同如：sheep→sheep, deer→deer, Japanese→Japanese, Chinese→Chinese等。

③ 有些名词形式上是单数，实为复数意义，通常被称为复数名词，如：people, police等。

④ 由-man和-woman构成的合成词如：policeman→policemen, Englishman→Englishmen，Englishwoman-Englishwomen但German不是合成词，故复数形式为Germans.另外被man 或woman 修饰的名词变复数时，两个名词都要变。例：a man doctor →two men doctors

a woman teacher→some women teachers 但: apple tree→apple trees

⑤ 有些名词只有复数形式，如：clothes, trousers, glasses, chopsticks等。

⑥数词+名词作定语时， 常采用数词+单数名词形式，如a two-week holiday,

an 8-year old girl.另一种常见的形式有five minutes' walk, two days' leave等。

3)不可数名词没有单复数形式，要表示不可数名词的数量，可用以下两种方法。

①用much, a little, a lot of /lots of some, any等修饰不可数名词。如：

The rich man has a lot of money.

②可用表单位的词修饰不可数名词， 如：a piece of paper, two pieces of paper,

a bottle of orange, a glass of milk, three bags of rice。

二、名词的格

1)表示有生命的东西(人或动物)的名词所有格一般在名词后加's .如：my father's study以s或es结尾的复数名词的所有格只在名词后加' 如： the teachers' reading room 教师阅览室;不以s结尾的复数名词的所有格要加's.如：the women's shoes 女式鞋子。如果一样东西为两人共有，则只在后一个名词的后面加's。如果不是共有的，则两个名词之后都要加's .如：Jane and Helen's room 珍妮和海伦的房间(共有)Bill's and Tom's radios 比尔的收音机和汤姆的收音机(不共有)

2)表示无生命的东西，一般用 of+名词的结构。如：a map of China
