问题描述：
The population of this city,forty percent of which ___,___15%in the last three years.
A are Germans;has risen
B are German;has fallen by
C is Germans;have increased to
D is Germans;has been reduced by
我记得German的复数是Germans,但这么看的话好象就一个都不对了,
答
B
首先这里的population表示集合概念,虽然是单数形式,但表示的是复数的含义,所以C、D删去～分辨A、B的时候主要看B有个by,能和后面的15％连接,所以综上选B了～
