（3）不定冠词的特殊位置
1）“so/ as/ too/ how/ however+ adj+ a/ an单数名词”。
  如：This is so interesting a film that we all want to see it.
      He is as good as a student as you (are).
      He is too young a boy to join the army.
      How clever a boy he is!（=what a clever boy he is! =How clever the boy is!）
      However clever a man he is, he can’t learn English well without enough practice.
2）quite, rather与单数名词连用且名词前有形容词修饰时，其顺序为“a+ rather+形容词+单数名词”或“rather/quite + a/an+形容词+单数名词”。如：
      It was a rather difficult question.
      It was rather a difficult question.
      It is quite a small house.
注意：①没有“a+ quite+形容词+单数名词”结构
      ②“quite+ a/an+单数名词”用于强调在某方面很突出。
        She is quite a beauty.
      ③在quite a few, quite a little等短语中，由于a few, a little为固定短语，故不能拆成a quite few, a quite little等
3）“no/ much/ far/ all…+形容词比较级+ a/an+ 单数名词”。如：
  He is far more clever a boy.
4)“more/less+形容词+a/an +单数名词”。
