Question

With more forests being destroyed in that area, huge quantities of land _______ deserts each year.

A．has been turned into	B．had been turned into
C．is being turned into	D．are being turned into

Answer 1

D

试题分析：考查主谓一致和现在进行时的被动：句意：随着森林在这个地区被破坏，每年都有很多土地正被变成沙漠。所以用现在进行时的被动式，而且主语是huge quantities of land，谓语是复数，选D。
点评：quantity这个单词，构成的短语，谓语是和quantity的单复数一致的，quantity是单数，谓语就是单数，quantity是复数，谓语就是复数，这题的时态就是根据上下文的句意判断。
