With more forests _____being destroyed, huge _____ of good earth _____ washed away each year.

A．are ; number ; is	B．/ ; quantities / are
C．be ; number ; are	D．/ ; quantities ;is

答案

B

解析

试题分析:考查非谓语动词和主谓一致。在with +宾语+补语构成的复合结构中，补语应该用doing；to do 或者done，由此可以排除A、C选项。Quantities of +复数名词或不可数名词做主语时谓语动词应用复数形式，所以B选项正确。
