a,形容词,名词的顺序是怎么样的啊

亲,在一些特殊句子和短语中,a和an的位置是不一样的,下面举三组例子：1)How interesting a story this is!=What an interesting story this is!——这个故事是多么有趣啊!2)It is too expensive a skirt for the poor。=It is such an expensive skirt for the poor。——对穷人而言,这条裙子太贵了。3)on so official an occasion=on such an official occasion——在这样正式的场合。记住这三组例子就可以了,希望能帮助到你^_^
