所有乐器名前都要加定冠词THE.五楼等的回答是正确的.一个冠词之差,但确有规范和不规范之区别.举例来说明: 问:Could I borrow your digital camera? 您的数码相机我能借用吗? 答:(A) It's out of question? 没问题. (B) It's out of THE question? 没门儿. 又如: (A) He went to jail (prison) yesterday. 他昨天坐牢去了. (B) His attorney went to THE jail (prison) yesterday. 他的律师昨天去了一趟监狱(办事去的). 仅一个定冠词之差. 应为:Are you playing the guitar?
