问题选择题

With more forests being destroyed, huge quantities of good earth __________ each year, which __________ that our environment is suffering.

A．are washing away, suggest

B．is being washed away, suggest

C．have been washed away, suggests

D．are being washed away, suggests

答案

答案：D

题目分析：根据句意每年都有好的土地流失，故用现在进行时态的被动式；第二空是定语从句，先行词是整个句子故谓语动词用单数。故选D。

点评：此题较易，首先是划分句子成分，根据时间状语确定时态；整个句子做先行词时定语从句谓语用单数。
