It has been quite a long time ______ the two companies established a business relationship.
A.although
B.because
C.if
D.since

参考答案

正确答案:A
解析:本题考查连词辨析。since引导的从句,可表示“自从……以来”,其主句用完成时态.从句用一般过去时。例如:Since he entered the university,he has made great progress in his studies. (自从他进入大学以来,他在学习上取得了巨大的进步。);although用来引导让步状语从句;because引导原因状语从句;if引导条件状语从句。根据句意,选项D正确。
