Question

一道英语单选题

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
答案和解释

Answer 1

答案：D
解释：当先行词是the only one时，定语从句的谓语动词用单数形式，再者for + 一段时间 与现在完成时连用，所以正确答案是D。
翻译：He is the only one of the students who _has been___ a winner of scholarship for three years.
在这些学生当中，他是唯一一个3年来都获得了奖学金的人。

祝你学习进步，更上一层楼！请记得采纳，谢谢！(*^__^*)

追问：for + 一段时间 通常与现在完成时连用，但是不是一定得用现在完成时。

Answer 2

A is 客观事实用一般现在时

追问

我也这么想，貌似大多数不这么想啊。。

Answer 3

D
后面有for three years 所以要用现在完成时
因为主语是第三人称单数HE， 所以选取D

Answer 4

He is the only one of the students who __D__ a winner of scholarship for three years.
A is B are C have been D has been
for three years决定了时态为现在完成时， a winner 决定了选D。

Answer 5

the only one of the students who
one of 句子中 one 前有only, just,最高级，序数词等修饰，one是先行词，who 后用单数。

Answer 6

D 啊 首先 for three years.要用完成时态
only one of the 要用单数 如果没有only就用复数
