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?
