单选题 ______ the company is upgrading its inter-office mailing system, employees will still proceed with their work as planned.
A. Even if
B. In short
C. As if
D. According

【正确答案】 A

【答案解析】中级问题空格内应填入连词，所以在A选项和C选项中通过分析词义来选择答案。这两个都是引导状语从句的连词，此时通常要通过分析词性和词义，同时，还要考虑单词的语法特点来解题。although=though=even if=even though，这是引导状语从句的连词中出题频率最高的。
[高频词语] proceed with one's work 继续进行某人的工作 as planned 按计划
