Question

With more forests _______, a huge quantity of good earth _______ every year.

A. being destroyed; is being washed away    B. are being destroyed; is being washed away

C. being destroyed; are being washed away    D. destroyed; are being washed away

Answer

A

【解析】考查被动语态和主谓一致。句意为“随着森林的被毁，大量的优质土壤每年都被冲走。With的复合结构中”forests与destroy之间是被动，故用being destroyed。a huge quantity后面动词用单数，而且此处土壤是被冲走，还要有被动，is being washed away 是进行时的被动语态。故选A。

【名师点睛】

主谓一致是常考题，要求考生平时多积累多记忆，根据具体语境进行选择。quantity组成的词组表示“许多，大量”可以修饰可数名词，或不可数名词。谓语的单复数应该和quantity的单复数保持一致，即quantity后面谓语动词用单数，quantities谓语动词用复数。
