问题描述：
Yesterday my sister bought ____ the one your sister bought last month.
A.as beautiful an umbrella as B.so beautiful an umbrella as
C.as a beautiful umbrella as D.so a beautiful umbrella as
答案怎么是A呢？
答
B. so beautiful an umbrella as相当于such an beautiful umbrella as
答
选B bought后接宾语，所以只能用 such a beautiful umbrella 或者 so beautiful an umbrella，虽然有时候as和such，so可以混用，但是这里as是不能用的，所以D改成 such a beautiful umbrella as也是对的
答
之所以选择A是因为as可以用在肯定句和否定句,但是so只能用在否定句,所以可以排除B和D了,这里as.as意为像.一样,根据句意可以看出这里是要我们选择像.一样漂亮,到这里就可以排除C了,答案就出来了.
答
B. so beautiful an umbrella as
