The people in the mountain village treated us like old friends _________ we were strangers to them.

The people in the mountain village treated us like old friends _________ we were strangers to them.
A. so that B. as if C. even though D. as long as
【答案】C
【解析】
【详解】考查从属连词。句意：即使我们对于他们来说是陌生人，山村里的人们还是像老朋友一样对待我们。A. so that以便，为了；B. as if好像；C. even though即使；D. as long as只要。根据句意，前一句说“村民们像老朋友一样对待我们”，后一句说“我们是陌生人”，两个句子之间应该是让步关系，因此用even though引导让步状语从句。so that引导目的状语从句/结果状语从句；as if引导方式状语从句；as long as引导条件状语从句。故选C项。
