17. In the text about Cliff Young, what does the word "amateur" refer to?A. A professional athlete with sponsorshipB. Somebody who does something because they enjoy it and not as their jobC. A coach who trains athletesD. A journalist covering sports events

本题考查对词汇“amateur”含义的理解，解题思路是根据对该词汇的常见释义，结合题目所给选项进行判断。

• “amateur”常见的释义为“业余爱好者”，其特点是做某事是出于兴趣爱好，而非将其作为职业。
• 分析各个选项：
  • A选项“A professional athlete with sponsorship”指的是有赞助的职业运动员，“professional”表明是职业的，与“amateur”的含义相反，所以A选项错误。
  • B选项“Somebody who does something because they enjoy it and not as their job”意思是因为喜欢做某事而做，并非作为工作，这与“amateur”作为业余爱好者的定义相符，所以B选项正确。
  • C选项“A coach who trains athletes”指的是训练运动员的教练，教练通常是有专业技能并以此为职业的人，并非“amateur”所表达的业余爱好者，所以C选项错误。
  • D选项“A journalist covering sports events”指的是报道体育赛事的记者，记者也是一种职业，不符合“amateur”的含义，所以D选项错误。
