Question

The ___ doctors in the country were attending the medical meeting to find out the real ____ of bird.
A. experience; cause B. experienced; reason C. top; cause D. top; reason
Which one? Why?
应该是bird flu.抱歉
答案是C，我选了B不知为何错了

Answer 1

选C.
1.语法上来说experienced和top都可以选,选top理由有两个：
一.意思上说,这个国家最优秀的医生聚在一起.比这个国家有经验的医生聚在一起.要顺很多,有经验的医生到处是,干了一定时间就可以说有经验的啦.
二.in the country是个范围,经验得出有范围的一般选最高级的.
2.cause作名词有起源、根源的意思,reason则是理由、理性等意思.
综合上述,C为佳选.
