中单选题In the major palm oil producing regions, Indonesia and Malaysia, it is estimated that almost one-third of forest loss in the past 10 years have been due to the expansion of oil palm.
A.is
B.are
C.has been
D.Were
参考答案：C
答案解析：这句话的意思是：在主要的棕榈油产区印度尼西亚和马来西亚，据估计，过去十年近三分之一的森林损失是由油棕的扩张造成的。该句考查主谓一致。almost one-third of forest loss in the past 10 years为主语，因为主语为单数意义，所以谓语动词用第三人称单数形式，排除B、D；此处表示过去发生的事情对现在造成的影响，要用现在完成时，排除A。因此答案为C。
