(单选题)
The underlined word “volatility” in the first paragraph means?
A.unpredictability
B.stability
C.vitality
D.prosperity
参考答案:A
参考解析:
词义猜测题。volatility意为“波动性,不稳定性”。根据第二自然段第一句“Mining and quarrying shrank by 4.7% in 2016, then rebounded, growing by 4.3% year-on-year in the first half of 2017.”可知采矿和采石业在2016年萎缩4.7%,然后反弹,2017年上半年同比增长4.3%。这些数值变化波动较大,不稳定,可以推测出volatility的意思应该是“不稳定的,上下波动的”。unpredictability意为“不可预测性,不稳性”;stability意为“稳定性”;vitality意为“活力”;prosperity意为“繁荣”。故选A。
