问题：一道选择题～Thewomansaw"alargecat"____ 
The woman saw "a large " _______ five yards  away from her.A.no more thanB.within答案是A但是解析里说no more than=within/only 那为什么不选B呢?
回答：其实，no more than这里只是，不超过。而within是介词，在...之内, 不越出。
The woman saw "a large cat" (no more than) five yards away from her. 

within 和away不能一起使用，如果用within 5 yards就已经表示在5码之内了，后接一个away纯属多余。
