单选题
With prices______so much, it is impossible for the company manager to stick to the original budget.
【正确答案】
C
【答案解析】[解析] 本句空格处意为物价波动很大。fluctuate意为“波动,涨落”,如:The price of vegetables and fruits fluctuates acoording to the season.(蔬菜和水果的价格随季节而波 动。)“wave(挥手)致意,(波浪)翻滚,(旗帜)飘动;swing摇摆,摆动,旋转;vibrate(使)振动,(使)摇摆”,这三个词都与句意不符,因此正确答案为C。
