题目:
He is the only one of the students who _____ a winner of scholarship for three years. A.is B.are C.have been D.has been
答案
D
解析
在“one of+复数名词+定语从句”中,定语从句一般被看成修饰复数名词,因此该从句的谓语用复数形式;在“the only one of+复数名词+定语从句”中,定语从句常看成修饰单数名词,从句谓语用单数形式。 This is one of the best novels that have appeared this year. He was the only one of the boys who was given a prize. 由此可以排除B和C; “for+时间段”是现在完成时态的时间状语,故选D项。
