Despite the previous rounds of talks，no agreement ________ so far by the two sides．（ ）

A. has been reached

B. was reached

C. will reach

D. will have reached

题目解答

答案

A. has been reached

解析

步骤 1：确定时态
根据时间状语 "so far"，句子应该使用现在完成时态。现在完成时态表示过去发生的动作对现在造成的影响或结果，或表示动作从过去某个时间开始，一直持续到现在。
步骤 2：确定语态
"agreement" 和 "reach" 之间是被动关系，因此应该使用被动语态。现在完成时的被动语态结构为 "have/has been + 过去分词"。
步骤 3：选择正确选项
A 项 "has been reached" 符合现在完成时的被动语态结构，且主语 "agreement" 是单数，因此使用 "has"。
B 项 "was reached" 是一般过去时的被动语态，不符合题意。
C 项 "will reach" 是一般将来时，不符合题意。
D 项 "will have reached" 是将来完成时，不符合题意。
