核心问题
In order to get married in this state, one must present a medical report along with his identity. 请分析句中的错误。
词典解答
identity是指“身份”，而identification(简称ID)才是指“证明身份的材料”（如identity card或identity certificate身份证），因此应将上句中的identity改为identification。请比较下列各句中的identity和identification：
-
He had lost his identity card, (= a document which shows one's identity) and was being questioned by the police. (LASED) 他丢失了身份证，正受到警察审查。
-
His only means of identification was his passport. (同上) 他的唯一证明他身份的材料是他的护照。
-
There is no clue to the identity of the thief. (ALD) 没有线索来证明小偷的身份。
