  大家好,我是sweet老师,可数名词的复数形式多种多样,究竟应该选择哪一个呢?这些例子为大家了用法,涵盖了小学阶大部分单词,白癜风网希望能对大家有所帮助。

  1、可数名词有单数、复数之分,

  名词复数形式的构成规则

  (1) 一般在名词词尾加“s”

  如teacher—teachers egg—eggs

  (2) 以s, x, sh, ch结尾的名词加es

  如class—classes box– boxes bus –buses watch–watches

  (3) 以辅音字母+y 的名词变y为i再加es

  如story—stories library—libraries,

  dictionary—-dictionaries hobby—hobbies

  (4) 以f, fe 结尾的名词,变f, fe为v加es

  如life —lives leaf —leaves half—halves

  knife—knives wolf-wolves wife—wives

  (5) 以o结尾的名词“英雄芒果土豆西红柿”加es

  hero—heroes mango— mangoes

  potato— potatoes tomato— tomatoes

  其余加s(目前所学的词) zoo—zoos kilo—kilos

  radio—radios photo— photos piano– pianos

  (6)不规则名词单复数形式

  如 child — children woman — women

  man —men foot—feet tooth—teeth

  有的可数名词单、复数形式相同,如 Japanese,Chinese,sheep,

  如 I have one sheep. He has two sheep.

  2、不可数名词没有复数形式

  不可数名词有(1)milk, water, juice, tea, ice;

  (2) food, rice, meat, fish, chicken, bread, cheese

  (3) paper, newspaper , hair, time, money, homework, housework

  不可数名词的数量常表示如下
