For 800 years Oxford and Cambridge universities ______ in everything from Nobel prizes to boat races.

A．competed	B．had been competing
C．have competed	D．compete

答案

C

解析

试题分析：考查时态。从时间状语For 800 years可以得知要使用现在完成时。故选Ｃ。句意：８百年来哈佛和剑桥在各方面都在竞争着，从诺贝尔奖到划船比赛。
点评：时态题的考查要注意关键词，同时要注意具体语境。本题首先确定与过去有关。但根据具体语境强调过去请假的事实，故使用一般过去时的被动语态。
即学即练：By the time you arrive in London, we _____ in Europe for two weeks.
A. had stayed      B. shall stay      C. will have stayed        D.have been staying
选Ｃ
