Question

Rainforests ____ and burned at such a speed that they will disappear from the earth in the near future.

A．cut

B．are cut

C．are being cut

D．had been cut

Answer 1

C

试题分析：从will disappear用的将来时，可推出，森林应是正在被砍伐，所以用现在进行时，Rainforests与cut之间是被动关系，故用现在进行时的被动语态。故选C。
点评：本题难度适中。动词的时态和语态放在一起考查增加了试题的难度，需要考生有分析理解复杂的句子结构的能力，必须会根据语境或已给动词的形式来判断动词的时态。
即学即练：]—May I see your ticket, please? I think you ________ in my seat.
—Oh, you’re right. My seat is upstairs. I’m terribly sorry.
A. are sitting B. sit C. sat D. have sat
解析：A。考查动词时态。句意：---我可以看一下你的票吗？我想你正在坐着我的座位。---你说得对。我的座位在楼上呢？很对不起。根据句意对方正在坐着我的座位可知选A。
