单选题 It seems that only Mary is eligible for the job.
A. prepared B. trained C. qualified D. guided

【正确答案】 C
【答案解析】eligible是“具有资格做某事”的意思,后面跟介词for。Prepared for和trained for固然都可以讲,但意思和eligible for不同,只有qualified for和eligible for同义。又如:To be eligible for the contest, one must have a CET 6 certificate.必须要有大学英语六级证书才有参赛资格。
