问题 Some studies confirmed that this kind of eye disease was ______ in tropic countries.(2005年电子科技大学考博试题)

选项 A、prospective
B、prevalent
C、provocative
D、perpetual

答案B

解析 本题是说一研究证实这种眼疾在热带国家很普遍。B项“prevalent普遍的、流行的”符合题意,如:The habit of travelling by aircraft is becoming more prevalent each year.(坐飞机旅行一年比一年普遍了。)其他三项“prospective预期的;provocative煽动的;perpetual永久的”都不正确。
