问题 According to some specialists, the number of earthquakes caused by volcanic activity ______ significantly over the last five years.
选项 A、increase
B、has increased
C、have increased
D、will have increased
答案B
解析 空格后出现了over the last five years，即“过去5年”的时间段，空格处需要填入从过去开始持续到现在的行为或状态的现在完成时的动词词形。但主语the number是单数，动词也要填表示单数的has increased。顺便说明一下，a number of作复数处理，而the number of作单数处理。
