问题 Doctors sometimes ______ old cures when modern medicine doesn’t work.
选项 A、fall on
B、fall down on
C、fall back on
D、fall in upon
答案 C
解析 题型：词汇题。fall back on意思是“借助于”，如：She has no relatives to fall back on．fall down (on)意思是“倒下，跪倒，失败，未能符合要求”。fall on意思是在什么时候发生、来临。比如：Her birthday will fall on a Friday this year．他今年的生日是在一个礼拜五。fall in upon意思是“不期而遇”。
