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

问题描述:

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.这题为什么选C不选D?在此多谢了.
为什么括号后单词不用Cuting burning?

就像楼上那位说的一样,D表示动作已经结束,而题目中是说现在正在被cut和burn.cut用进行时表示动作的正在进行,burn因为是被烧,所以用被动(和前面的cut 公用一个动词are),就是这样子.我是英语专业大二的学生,
