问题描述:

When reports came into London Zoo that a wild puma had been spotted at 45 miles south of London
为什么不能加个at 表示在.地方

When reports came into London Zoo that a wild puma had been spotted 【at】 45 miles south of London.
这里面的at是你自己加的吧,这是不对的.45 miles south of London.在这里作地点状语,状语前十不能加介词的.
相似的用法还有时间状语 last night/day,the day after yesterday等等
