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 该题是词汇题,考查动词短语意义辨析。短语fall on sb./sm.表示“袭击、抓住”,如:The children fell on the food and ate it greedily.孩子们扑向食物,狼吞虎咽地吃起来。没有短语fall down on,只有fall down,意思是“不令人满意”,如:And that’s where the theory falls down.这就是该理论的不足之处。短语fall back on sb./sth.表示“(转而)求助于”,如:I have a little money in the bank to fall back on.我银行里还有一点钱可以在需要时动用。没有短语fall in upon,只有fall in with sb./sth.,表示“同意、赞成”,如:She fell in with my idea at once.她立即同意我的主意。因此,根据题意,选项C为最佳答案。
