The 【rollercoaster】 that the financial markets were facing during last week took its toll on the commodities markets as well.
A、ups and downs
B、depression
C、opportunities
D、competition
【正确答案】:A
【名师解析】:题目中的"rollercoaster"是一个比喻,用来描述金融市场在上周所经历的剧烈波动。这种波动性通常意味着市场经历了快速的上升和下降,就像过山车一样。选项A "ups and downs"直接对应了这个比喻,表示市场有上升和下降的波动。选项B "depression"通常指经济衰退,与题目中的描述不符。选项C "opportunities"可能在某些情况下是波动的结果,但不是对"rollercoaster"的直接描述。选项D "competition"与题目描述的市场波动无关。因此,正确答案是A "ups and downs"。
