好难啊，还没有答案，大家帮帮忙吧，快考试了

10.  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

我的思路

一，both and 结构要求对称．Both on … and on…或者on both ….and …,Ａ明显错误

　　Both…as well as　有此结构么???

二，平行结构：Ａ，Ｂ，and C

                    On A, B, and C

                    On A, on B, and on C(看第二个)．．．．．．Ｂ，Ｃ明显错误

四，dependent 和depending的差别？？？

答案是Ｄ么？

can=be able to >be capable of

            In that> because

     全部没用上．．．．

　还出现了个Being +adj．

疑惑．．．．．．．．．

我得分析

both... and应该是唯一正确得结构

its size, climate, and altitude不好,给人感觉是its size, (its) climate, and (its) altitude

我觉得是两个因素得并列,its size和climate and altitude

depending,dependent区别

这里应该用分词结构

我觉得C是对的

豁然开朗．谢谢谢谢

xiaoxi_rina

为什么用depending呢?? 还是不太明白!

谢谢!!

答案是A吧,able to有主观意味，另外Ｃ有逗号造成sentence fracture．主从句不应该用逗号歌开

我做题是后就觉得tree作为一个无生命的东西，用be able to do 是不是不好……
