Question

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

A．is washing away	B．is being washed away
C．a(chǎn)re washing away	D．a(chǎn)re being washed away

Answer 1

D

解析試題分析：主謂一致與動詞的語態(tài)。做此類題目需要注意quantities of 即可修飾可數(shù)名詞也可修飾不可數(shù)名數(shù)，而謂語動詞與quantities保持一致即復數(shù)，如果是a quantity of 謂語動詞由為單數(shù)形式。根據(jù)題意謂語動詞應用復數(shù)形式，排除AB兩項。而earth 與wash away 之間是被動關系，所以選擇D項。
