This is one of the best films .

A. that have been shown this year

B. that have shown

C. that has been shown this year

D. that you talked

答案：

(答案→)A. that have been shown this year

B. that have shown

C. that has been shown this year

D. that you talked

解析：本句话的先行词应该是films,因此，关系代词that是负数概念，其谓语动词应用复述的被动语态have been shown。如果句中的one前面使用了定冠词the，则the one应该视为先行词。
