四级英语语法名词用法详解6:hair与hairs

a. he must be very old. look，he has grey ________.

b. he found some ________ in his soup.

a. hair，hair b. hairs，hairs c. hair，hairs d. hairs，hair

此题应选 c，容易误选 a，误认为hair永远不可数。其实hair这个词既可以是可数名词，也可以是不可数名词，只是含义稍有变化：

1. 作为可数名词，是指一根一根的“头发”或“毛发”：

look at this, a hair in my soup. 你瞧，我的汤里有根头发。

the cat has left her loose hairs all over my clothes. 猫掉的毛弄得我衣服上到处都是。

my father has quite a few gray hairs. 我父亲已有不少白发。

there is not a gray hair on his head. 他头上没有一根白头发。

2. 作为不可数名词“头发”的总称，是集合名词：

i’ll have my hair cut. 我要去理发。

he has blond hair. 他有一头金发。

she has a beautiful head of hair. 她有一头漂亮的头发。

the woman likes to do her hair in foreign style. 这个女人喜欢把头发梳成外国式。

试比较以下句子：

he has grey hair. 他满头白发。

he has grey hairs. 他有些白发了。
