The yield per acre of coffee berries varies enormously in that a single tree, depending on both its
size and on climate and altitude, could produce enough berries to make between one and twelve
pounds of dried beans a year.
(A) enormously in that a single tree, depending on both its size and on climate and altitude, could
produce
(B) enormously in that a single tree, dependent on its size and also on climate and altitude, is able
to produce
(C) enormously, because a single tree, depending on its size and on climate and altitude, is able to
produce
(D) enormously, because a single tree, being dependent on its size, climate, and altitude, is
capable of producing
(E) enormously, because a single tree, dependent both on its size as well as on climate and altitude,
could produce
根据补充说明：
[1] Depending on… 和 dependent on… 均为合理的用法，因此这两者之间的区别并非本题的考点。
[2] 此句描述的为一个客观事实，且主句位于varies属于一般现在时，所以because引起的从句也以一
般现在时为佳，因此在时态上，BCD相较AE为佳。但除此之外，can/ be able to/ be capable of
的区别和优劣不是本题的考点。
且：both…and also以及both…as well as均错误
最后停在BC上面了，答案选C
我的问题是：我不觉得dependent on its size and also on climate and altitude有什么错误啊！
而且相对于C,B也有"且"的含义……
请指教…… |
