标题: 难道推翻了推翻了be able to 只能限于人？！！！
Q29: PP-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

a single tree 可以用 be able to ？？？不是说只能用于人的吗？啊啊啊。。。

基本确定be able to是可以修饰人的，can和be able to 的区别不在于主语是物还是人，而是主语是不是“主动发出动作者”，例如the hen is able to lay eggs的表达是正确的。

can 难道就不是主动发出动作者吗？请详解哈！谢谢~

你这个例句是哪来的呢？我查朗文没看到有接物的。。。

can的适用范围更广一些，意思仅表达做某种事情的可能性，而be able to表达的是主语有发出动作的能力，两者意思有细微差别，遇到题一般还是要参考其他考点进行选择，不算绝对性错误。

母鸡的例句是自己编的……源于一个tree is able to的句子，tree的这个句子来源于一份商业计划书，应该比较正式

其实MM可以不是很纠结这个问题，因为中文和英文都有比喻义一说
GMAT是语意和逻辑为王的
