1) 不定冠词位置
不定冠词常位于名词或名词修饰语前。注意:
a. 位于such,what,many,half等形容词之后。例如:
I have never seen such an animal. 我从来没见过这样的动物。
Many a man is fit for the job. 许多人适合这岗位。
b. 当名词前的形容词被副词as, so, too, how, however, enough修饰时,不定冠词应放在形容词之后。例如:
It is as pleasant a day as I have ever spent. 我从未这么高兴过。
So short a time 如此短的时间
Too long a distance 距离太远了
c. quite,rather与单数名词连用,冠词放在其后。但当rather,quite 前仍有形容词,不定冠词放其前后均可,如:rather a cold day/a rather cold day.
d. 在as,though 引导的让步状语从句中,当表语为形容词修饰的名词时,不定冠词放形容词后。例如:
Brave a man though he is,he trembles at the sight of snakes. 他尽管勇敢,可见到蛇还是发抖。
2) 定冠词位置
定冠词通常位于名词或名词修饰语前,但放在all, both,double,half,twice,three times等词之后,名词之前。例如:
All the students in the class went out.班里的所有学生都出去了。
