选择题
It is hard for the Greek government to get over the present difficulties_____ gets more financial support from the European Union.
A．if
B．unless
C．because
D．since
答案
答案：B
根据句意可知“除非有来自欧洲联盟的更多的经济支持，否则希腊政府很难克服目前的困难”，只能选择unless“除非”才能使句意完整。考查状语从句的连词题事实上非常简单，只要找到句中的关键词，然后从句意上去排除就行了，本题关键词是hard和more financial support。
