以下是為大家整理的關(guān)于小學(xué)英語(yǔ)基本語(yǔ)法與練習(xí)之名詞的文章,希望大家能夠喜歡! 知識(shí)要點(diǎn)
    一、名詞的數(shù)
    在英語(yǔ)中,名詞按其所表示的事物的性質(zhì)可分為可數(shù)名詞和不可數(shù)名詞??蓴?shù)名詞有單數(shù)和復(fù)數(shù)兩種形式。單數(shù)名詞表示一個(gè)可數(shù)事物。復(fù)數(shù)名詞表示兩個(gè)或兩個(gè)以上的可數(shù)事物。可數(shù)名詞可分為單數(shù)和復(fù)數(shù)兩種形式:表示一個(gè)人或事物的名詞用單數(shù)形式,在使用時(shí),前面一般加不定冠詞a或an,表示兩個(gè)或兩個(gè)以上的人或事物的名詞用復(fù)數(shù)形式,一般是在詞干后附加詞尾s 或es,如:bags ,boxes.名詞單數(shù)變復(fù)數(shù)具體規(guī)則如下:
    1).規(guī)則變化
    ①一般在名詞后加s.如boy→boys, pen→pens等。
    ②以s, x, sh, ch結(jié)尾的,在后面加es.如class→classes,但stomach的復(fù)數(shù)為stomachs.
    ③"以輔音字母+y"結(jié)尾的,y變?yōu)閕,然后再加es.如baby→babies.
    ④以f或fe結(jié)尾的名詞把f或fe改為v, 再加es. 如knife, half, leaf, wolf等。
    ⑤以o結(jié)尾的名詞,除tomato, potato等少數(shù)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).不規(guī)則變化
    ① man→men, woman→women, foot→feet, tooth→teeth,,child-children,mouse→mice
    ② 單復(fù)數(shù)形式相同如:sheep→sheep, deer→deer, Japanese→Japanese, Chinese→Chinese等。
    ③ 有些名詞形式上是單數(shù),實(shí)為復(fù)數(shù)意義,通常被稱(chēng)為復(fù)數(shù)名詞,如:people, police等。
    ④ 由-man和-woman構(gòu)成的合成詞如:policeman→policemen, Englishman→Englishmen,Englishwoman-Englishwomen但German不是合成詞,故復(fù)數(shù)形式為Germans.另外被man 或woman 修飾的名詞變復(fù)數(shù)時(shí),兩個(gè)名詞都要變。例:a man doctor →two men doctors
    a woman teacher→some women teachers 但: apple tree→apple trees
    ⑤ 有些名詞只有復(fù)數(shù)形式,如:clothes, trousers, glasses, chopsticks等。
    ⑥數(shù)詞+名詞作定語(yǔ)時(shí), 常采用數(shù)詞+單數(shù)名詞形式,如a two-week holiday,
    an 8-year old girl.另一種常見(jiàn)的形式有five minutes' walk, two days' leave等。
    3)不可數(shù)名詞沒(méi)有單復(fù)數(shù)形式,要表示不可數(shù)名詞的數(shù)量,可用以下兩種方法。
    ①用much, a little, a lot of /lots of some, any等修飾不可數(shù)名詞。如:
    The rich man has a lot of money.
    ②可用表單位的詞修飾不可數(shù)名詞, 如:a piece of paper, two pieces of paper,
    a bottle of orange, a glass of milk, three bags of rice。
    二、名詞的格
    1)表示有生命的東西(人或動(dòng)物)的名詞所有格一般在名詞后加's .如:my father's study以s或es結(jié)尾的復(fù)數(shù)名詞的所有格只在名詞后加' 如: the teachers' reading room 教師閱覽室;不以s結(jié)尾的復(fù)數(shù)名詞的所有格要加's.如:the women's shoes 女式鞋子。如果一樣?xùn)|西為兩人共有,則只在后一個(gè)名詞的后面加's。如果不是共有的,則兩個(gè)名詞之后都要加's .如:Jane and Helen's room 珍妮和海倫的房間(共有)Bill's and Tom's radios 比爾的收音機(jī)和湯姆的收音機(jī)(不共有)
    2)表示無(wú)生命的東西,一般用 of+名詞的結(jié)構(gòu)。如:a map of China
