问题 With prices______ so much, it’s hard for the company to plan a budget.

选项 A、fluctuating
B、waving
C、swinging
D、vibrating

答案A

解析 这是一组意义相近的词,测试考生辨异的能力。fluctuate“波动,涨落”,指经常的不规则的变化,常用来形容price,value等抽象概念,如:the fluctuating market;wave“像波浪一样起伏不平,挥动”,如:to wave a handkerchief,wave good—bye;swing“来回地摆动”,多指某物上端固定,下端摆来摆去,如:A pendulum swings.“钟摆来回摆动。”She swung her arms as she walked.“她走路时胳膊摆来摆去。”vi—brate作“振动,颤动”讲,指短时间内剧烈地摇动,如:The ground vibrated duringan earthquake.“地震时大地剧烈地颤动。”
