商务印书馆2014年9月第1版《英语词语用法详解词典》指出:“在现代英语中, where 可以与 from, to, at 等介词连用。” 所以 “Could you tell me where the library is at?”这句话是对的。当然,更常用的应该是:Could you tell me where the library is ?
(1)could you tell me where the library is at?这句话对吗?
强烈建议在正式英语考试中优先使用下面句子结构;
It is strongly suggested that the following sentence should be adopted in preference to the mention-above one because the first sentence is likely to be considered to be false or wrong.
