dictionary復(fù)數(shù)形式怎么寫(dictionary的復(fù)數(shù)和用法例句)

大家好,我是sweet老師,可數(shù)名詞的復(fù)數(shù)形式多種多樣,究竟應(yīng)該選擇哪一個(gè)呢?這些例子為大家總結(jié)了用法,涵蓋了小學(xué)階大部分單詞,希望能對大家有所幫助。

 

小學(xué)英語——六種單詞認(rèn)識可數(shù)名詞的復(fù)數(shù)形式

 

1、可數(shù)名詞有單數(shù)、復(fù)數(shù)之分,

名詞復(fù)數(shù)形式的構(gòu)成規(guī)則:

(1) 一般在名詞詞尾加“s”

如:teacher—teachers egg—eggs

(2) 以s, x, sh, ch結(jié)尾的名詞加es

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

(3) 以輔音字母+y 的名詞變y為i再加es

如:story—stories library—libraries,

dictionary—-dictionaries hobby—hobbies

(4) 以f, fe 結(jié)尾的名詞,變f, fe為v加es

如:life —lives leaf —leaves half—halves

knife—knives wolf-wolves wife—wives

(5) 以o結(jié)尾的名詞“英雄芒果土豆西紅柿”加es

hero—heroes mango— mangoes

potato— potatoes tomato— tomatoes

其余加s(目前所學(xué)的詞) zoo—zoos kilo—kilos

radio—radios photo— photos piano– pianos

(6)不規(guī)則名詞單復(fù)數(shù)形式

如: child — children woman — women

man —men foot—feet tooth—teeth

有的可數(shù)名詞單、復(fù)數(shù)形式相同,如 Japanese,Chinese,sheep,

如: I have one sheep. He has two sheep.

2、不可數(shù)名詞沒有復(fù)數(shù)形式

不可數(shù)名詞有:

(1)milk, water, juice, tea, ice;

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

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

不可數(shù)名詞的數(shù)量常表示如下

two bottles of milk a cup of juice half a kilo of cheese

a bag of rice three kilos of meat some water
