语法——名词复数
Part 1:知识点
一、名词单数变复数的一般规则：
一般情况：直接在词尾+s，例如：bird-birds book-books pen-pens
以-s，-sh，-ch，-x，-z结尾的名词：在词尾+es，例如：bus-buses watch-watches box-boxes
大多数以-o结尾的有生命的名词：在词尾+es，例如：tomato-tomatoes potato-potatoes hero-heroes
以0结尾的无生命的名词：在词尾+s，例如：photo-photos piano-pianos radio-radios
以辅音字母加y结尾的名词：把y变为i再加es，例如：baby-babies family-families story-stories
以f和fe结尾的大多数名词：把f或fe变为v再加es，例如：wife-wives leaf-leaves knife-knives
二、不规则名词的复数形式
由元音字母的变化构成：man-men tooth-teeth foot-feet mouse-mice woman-women
单复数同形：sheep deer fish（也可以是fishes）
【拓展】fish在做"鱼类"讲时是可数名词,名词复数 ( https: / / wenwen. / s / w=%E5%90%8D%E8%AF%8D%E5%A4%8D%E6%95%B0&ch=ww.xqy.chain" \t "https: / / wenwen. / z / _blank )形式为fishes(因为以_sh结尾的名词变为复数时不加s,而是es);另外,fish在做笼统的"鱼"讲的时候,是不可数名词,这个时候可不加es。
例句：There are many fish in the sea.海里有许多鱼。
There are many kinds of fishes in the supermarket.超市里有许多种类的鱼。
有些名词变为复数时加-en:child-children ox-oxen
