名词的复数形式
(包括规则的变化和不规则的变化)


++++++++++++++++++++++++++++++++++++++++++++
规则的变化有以下几种:


1. 直接加s 


2. s,sh,ch,x结尾的单词要加es。以s结尾的单词要加es,这个应该不会弄错,不然一个单词的复数形式的尾巴就是ss了。但是sh,ch结尾就很容易被忘记,而且因为在he,she,it做主语的一般现在时里,动词也是这种变化,所以一定要记住. 比如watch->watches(手表;); finish->finishes....x结尾的倒不是很多见(boxes)


3. 以辅音字母加上y结尾的单词,去掉y加上ies. 大家容易忽略的就是y前面一定要是辅音字母才要做这样的变化,像boy就不符合这个条件, 平时记清楚了才不会在考试的时候突然犯迷糊。这种符合条件的例子有:baby->babies....y结尾的专有名词,则直接加s变复数,如the Henrys(亨利一家)


4.o 结尾的名词,变复数时,大多数都是直接加s, 除了hero, negro,potato,tamato这四个加es.


5.ffe 结尾的名词变复数时,可以是加s,如:belief->beliefsroof->roofs; 也有去f,fe ves,如half->halves,knife->knives,leaf->leaves,wolf->wolves,wife->wives,life->lives,thief->thieves;没有什么确定的变化规则,去f,fe ves常用的都在这里了,多看几眼就记住了吧。还有handkerchief可以有handkerchiefs或者handkerchieves的变化,是特例里面的特例了。
