中文是：
我原以為她和妳一樣都是強悍的女孩，但現在恐怕她不是。
英文：
I thought she was _____ you before, but now I am afraid she is not.
(A) as tough a girl as
(B) as a tough girl as
(C) as a girl as tough
(D) as a girl tough as
我選(B)結果是錯的
答案應該是(A)
但我一直搞不太懂為什麼是(A)
希望強者解答 謝謝！

as+形容詞+名詞+as例：You are as good a student as she (is).(你和她都是好學生)
