Question

With the country’s population reaching 1.6 billion in the mid of this century, most of China’s rivers, including the Yellow River, ________.

A．is drying up

B．will be drying up

C．dry up

D．have dried up

Answer 1

B

考察时态及语态。句意：随着本世纪中期国家的人口达到十六亿，中国大部分河流，包括长江都会干涸。Dry up弄干，河流是被弄干的对象，故用被动语态。结合句意可知描述的将来的动作，故用将来时，选B。
