名词的词形变化
1.不规则复数形式
1)来自古英语的复数形式,如:
child---children foot---feet tooth---teeth goose---geese

bacterium---bacteria nucleus---nuclei fungus---fungi stimulus---stimuli
alumnus---alumni focus---foci radius---radii terminus---termini

#当代美国英语中往往把data当做单数用,因此常见到复数形式datas。另外,lens是一个单数可数名词,其复数形式为lenses。
1)词尾读音为[f]并以-f或0-fe结尾的名词复数形式有以下几种情况:
a)规则形式:

wolf---wolves
c)既可是规则形式又可是不规则形式:

3.不可数名词
不可数名词前一般不需要加定冠词,永远不能加不定冠词!
例如下列用法均属错误:
the mathematics the banking a cloth an equipment
不可数名词作主语,谓语要用单数形式。
如:Water is important.
但如果不可数名词前面被piece,drop,set等词修饰时,谓语应该与piece,drop,set等的单复数形式保持一致
例如:Few drops of water are needed to save the flower.
下面是典型的不可数名词,是应该熟记的!!

请特别注意其中以-s结尾的不可数名词,大家平时应该积累遇到的不可数名词
!!注意下列可数名词!!

英语中有许多名词既可作可数,又可作不可数。如:hair作“人或动物的毛”的时候是可数名词,作头发解释时是不可数名词。判断一个词是否可数,除了记忆以外, 主要看题中该名词的修饰词来决定。如:much只能修饰不可数名词
4.单数形式和复数形式的词义不同的名词
英语中有些名词的复数形式的词义不同于单数形式,如:

authority(权利)---authorities(当局) cloth(织物)---clothes(衣服) content(含量)---contents(目录)
