问题 ________ you have specific training to deal with everyday emergencies, you should never hesitate to contact us.

选项 A、In case
B、As if
C、Even if
D、Ever since

答案 A

解析 本题考查状语从句的用法。In case意为“万一,假设”,用于引导条件状语从句,分析句意可知,本题答案为A)。As if意为“似乎,好像”,常用于引导表语从句和方式状语从句;Even if意为“尽管,即使”,常用于引导条件状语从句和让步状语从句;Ever since意为“自从”,可用于引导时间状语从句。以上三项与句意不符。均可以排除。
