不定冠詞常位于名詞或名詞修飾語前。注意：
a. 位于下列形容詞之后：such, what, many, half
I have never seen such an animal.
Many a man is fit for the job.
b. 當名詞前的形容詞被副詞 as, so, too, how, however, enough 修飾時，不定冠詞應(yīng)放在形容詞之后：
It is as pleasant a day as I have ever spent.
So short a time.
Too long a distance.
c. quite, rather 與單數(shù)名詞連用，冠詞放在其后。
但當 rather, quite 前仍有形容詞，不定冠詞放其前后均可。如：quite a lot
