Question

With more forests being destroyed, huge quantities of good earth ______ each year.

A．is washing away	B．is being washed away
C．are washing away	D．are being washed away

Answer 1

D

解析试题分析：主谓一致与动词的语态。做此类题目需要注意quantities of 即可修饰可数名词也可修饰不可数名数，而谓语动词与quantities保持一致即复数，如果是a quantity of 谓语动词由为单数形式。根据题意谓语动词应用复数形式，排除AB两项。而earth 与wash away 之间是被动关系，所以选择D项。
考点 主谓一致与动词的语态。
