语法知识详解

一、名词的分类

名词可分为普通名词和专有名词。普通名词可以分为可数名词和不可数名词,可数名词又包括个体名词和集体名词,不可数名词包括物质名词和抽象名词。

二、可数名词

可数名词[C]就是可以计数的名词,有单数、复数两种形式,绝大多数可数名词的复数形式通过在词尾加上-s或-es构成。可数名词单数时可以跟不定冠词a/an,复数时可以跟数词one,two,three等。

可数名词复数一般在词尾加-s,在清辅音后读/s/ [parents,steps],在元音及浊辅音后读/z/ [sides,friends],单词词音以/s/, /z/, /dʒ/, /ʃ/, /ʒ/结尾时读/iz/ [changes,horses]。

以-s/-x/-sh/-ch结尾的词加-es,一般读作/iz/ [glasses,brushes,watches,boxes]。

以-o结尾的词加-s,一般读作/z/ [pianos,photos,zoos]。

以辅音字母加-y结尾的词,变-y为-i加-es,一般读作/iz/ [factories,studies];以元音字母加-y结尾的词,直接加-s,一般读作/z/ [toys,boys,ways,days]。

以-f或-fe结尾的词,把-f或-fe变为-v加-es,一般读作/vz/ [wolves,wives,thieves]。

注意:

① stomach的复数形式是stomachs。

② hero,potato和tomato的复数形式是在单词后加-es。

③ roof,belief,proof等词的复数形式是在单词后加-s。

④ 常见可数名词的不规则变化:foot–feet,man–men,woman–women,tooth–teeth,mouse–mice,goose–geese,child–children。

⑤ 常见单复数同形的名词:sheep,deer,spacecraft,aircraft,Chinese,Japanese,Swiss,means,series,species。

⑥ 常见外来名词的复数形式:criterion–criteria,phenomenon–phenomena,analysis–analyses,basis–bases,crisis–crises,bacterium–bacteria,medium–media。

⑦ fish表示鱼的种类时复数形式是fishes,表示条数时复数形式为fish,表示鱼肉是不可数名词。

⑧ 中间没有连字符也没有间隔的复合名词,将最后一个名词变为复数:housewife–housewives,bookshelf–bookshelves;中间有连字符或间隔的复合名词,将其中主要的词变为复数:passerby–passers-by,daughter-in-law–daughters-in-law,editor in chief–editors in chief。

⑨ 组成复合名词的单词中没有名词时,则在最后一个单词的词尾加-s:go-between–gobetweens,grown-up–grown-ups。

⑩ 由man,woman作为复合名词的第一部分时,将两部分都变为复数形式:man cook–men cooks。

a) 个体名词表示一类人或物的个体

三、不可数名词

不可数名词[U]就是不可以计数的名词,它不可以跟不定冠词或数词。有的名词有时虽然也可能以复数形式出现,但不能计数,比如可以说many difficulties,却不可以说three difficulties。

六、名词构成法(合成法)

名词的格有两种构成方式,一种是在单数名词和不以-s结尾的复数名词后加-’s,或在以-s结尾的复数名词的词尾后加-’;另一种是of+名词。
