. _______ conflict among city-states caused the eventual decline of Greek civilization.
A、Continuous
B、Continual
C、Constant
D、Contrary
【正确答案】：B
【题目解析】：B【句意】城邦之间不断的冲突导致了希腊文明最终的衰落。【解析】continual意为“经常不断的，常常的（中间可能有间隔）”，如：Continual smoking is bad to one's health．经常抽烟有害身体健康。continuous 指连续不断而且绝对不中断，如: The continuous work made me completely exhausted. 不间断的工作使我筋疲力尽。constant可用来指习惯性的重复，如：Constant practice will make you overcome difficulties．经常训练会使你克服困难。 contrary作“相反的”讲，如： Any contrary policy is absolutely wrong. 任何相反的政策都是绝对错误的。
