Question

一道英语题“This is one of the best films__________this year"

Answer 1

选C
that（引导最高级修饰伍桥的定语从句先行词，定语从句的先行词被最高级修饰时，不能省略引导词，在这里相当于从句的主语） have been shown（相当于从句的谓语） this year（相当于从句的时间状语）

可对比一下两个句子：
1.This is the one of the best films _______. C. that has been shown this year
此句强调这是今年已经上映的唯一的一部最佳电影。that=the one(film),所以谓语答逗动词用单数has been shown.
2.This is one of the best films ______. A. that have been shown this year
此句强调这是今年已经上映腔举猛了的最佳电影之一。that= the best films,所以谓语动词用复数have been shown.
