零冠词用法的六个易错点
所谓用零冠词，即既不用定冠词，也不用不定冠词。以下几点需注意，不要用错：
(1)表泛指的不可数名词或复数名词前
Blood circulates in the body. 血液在体内循环。
Water consists of hydrogen and oxygen. 水由氢和氧组成。
Money circulates quickly in times of inflation. 货币在通货膨胀期间流通很快。
Trees don’t grow in the Antarctic. 南极不长树木。
Children are very hard on their shoes. 小孩子穿鞋很容易破。
比较：
Blood is thicker than water. 水浓于水。
Don’t put the water in the blood. 不要把这些水放到这些血里面去。
(2)倒装的让步状语从句中
在as(虽然)引导让步状语从句前面的单数可数名词前不用冠词。如：
Boy as he is, he likes to play with girls. 他虽是个男孩，但却喜欢与女孩子玩。
Big puzzle as it was, it hadn’t got the better of Jim. 虽然是个大难题，但仍没有难倒吉姆。
(3)某些特殊词前
例如在man(人，人类), word(消息)的前面不用冠词。如：
How did Man first discover fire? 人类最初是怎样发现火的?
Man is a rational animal. 人是有理性的动物。
Man is fighting a battle against pollution. 人类正在同污染进行斗争。
Word came that he could not come. 消息传来说他不能来了。
又如动词 turn(变成)，go(变成)后作表语的名词前通常用不用冠词。如：
He turned writer after he graduated from a medical college. 他从医学院毕业后成了作家。(比较：He became a writer after graduating from college.)
(4)独立主格结构中
在表示伴随或补充说明用用的独立主格结构中，名词前不用冠词。如：
He sat back, glass in hand. 他手里拿着酒杯向后一靠。
He stood there, pipe in mouth. 他站在那里，嘴里衔着烟斗。
She stood in the doorway, hands on hips. 她双手叉腰站在门口。
Sylvia, camera in hand, asked, “Where do we go first?” 西尔维娅手里拿着相机问道：“我们先去哪里？”
(5)“(a) kind [sort] of＋名词”结构的“名词”前
该结构中的“名词”不管是单数还是复数，其前都通常用零冠词。如：
Have you dreamt what kind of person you would be? 你曾梦想过自己要成为什么样的人吗？
This kind of fish lives in fresh water. 这种鱼生活在淡水中。
Not every kind of bird can fly. 不是每一种鸟都能飞。
I only like this kind [sort] of flower (bread). 我只喜欢这种花(面包)。
(6)表抽象意义的单数名词前
当单数可数名词含义抽象化具有形容词意味时，通常用零冠词。如：
He was fool enough to spend all the money at once. 他真傻，把钱一下子全花了。
He was not man enough to face up to his responsibility. 他没有足够的勇气去承担责任。
I was fool enough to believe him. 我竟然相信他，真够傻的。(=I was so foolish that I believed him. )
He was fool enough to tell them everything. 他真傻，把一切事情都告诉他们了。(=He was so foolish that he told them everything.)
