语法与词汇20.Peter was seen crying when he came out of the office. We can deduce that he must have been punished.
【正确答案】
D
【答案解析】本题中，deduce的意思是“推断，推论”。四个选项中，infer的意思是“推断”，如：I infer from your letter that you have not made up your mind yet．(我从你信中推想，你还没有下决心。)confer的意思是“授予，赠予”；refer的意思是“谈及，归诸于”；prefer的意思是“更喜欢，宁愿”。只有D符合题意。
