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

考察時態(tài)及語態(tài)。句意：隨著本世紀(jì)中期國家的人口達(dá)到十六億，中國大部分河流，包括長江都會干涸。Dry up弄干，河流是被弄干的對象，故用被動語態(tài)。結(jié)合句意可知描述的將來的動作，故用將來時，選B。
