答案:waiter
【分析】:You heard: I've just finished a short-term contract as a courier, and now I'm working as a waiter in one of the big hotels.
You match: part-time job=short-term, now=____
You recall: "courier" ? waiter?
You judge: waiter (Reason 1: 'waiter' is presented later. Reason 2: "courier" is difficult, maybe you don't know how to spell it at all. Reason 3: the examiner predicts that examinees may get panic in hearing "courier" as it is less used. Then the real answer might be missed out.)
You learn: He worked as a motorcycle courier 他的工作是骑摩托车送快递。英[ˈkʊriə(r)]
