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.

The yield per acre of coffee berries varies enormously, because a single tree, depending on both its size and on climate and altitude, is able to produce enough berries to make between one and twelve pounds of dried beans a year.

如果看到这两个选项，你们会选什么？正确选项是第二个，我觉得首先in that在句中，没有错误。你觉得那？产量的不同，应该取决于a single tree有可能produce。。。而不是有能力produce啊，could和 be able to 的区别不就是一个是有能力，一个是有可能，谁给我指点一下？

awishtosuccess

我顺着正确答案思路,我觉得问题是在DEPENDING 那里.高人请指点

记得OG里说in that过时了要不就是wordy，用because

aeoluseros

can = to be able to do something or to know how to do something.
can多了一重意思，所以用be able to更好.

in that和because的区别在置顶帖里有

简言之in that 是从一个角度解释，because引导“全局解释”

这里并没有从某一个角度解释，所以用because。

谢谢大家指点
但是in that是从一个角度解释，because从全局解释，好像有点感觉，但是理解还不是很明白，版主再帮我点化一下吧。
引用Gemj 的理解：在解释差异或说明有何特别之处时，in that比because更贴切。而且，主要是用在这个时候。下面是几个例子。

19.    Teratomas are unusual forms of cancer because they are composed of tissues such as tooth and bone not normally found in the organ in which the tumor appears.
(A) because they are composed of tissues such as tooth and bone
(B) because they are composed of tissues like tooth and bone that are
(C) because they are composed of tissues, like tooth and bone, tissues
(D) in that their composition, tissues such as tooth and bone, is
(E) in that they are composed of tissues such as tooth and bone, tissues
答案（E）

(C) world when they proclaimed a sacred truce for the festival month
(D) world, for a sacred truce was proclaimed during the month of the festival
(E) world by proclamation of a sacred truce that was for the month of the festival
A中in that使用不当,它一般用于表示相同或不同之处的原因.另外被动也不好。

答案：E

(A) stimulates behavior in the mouse and in humans, whereas adenosine stimulates behavior in humans only
(B) has mixed effects in the brain, whereas adenosine has only a stimulatory effect
(C) increases cyclic AMP concentrations in target neurons, whereas adenosine decreases such concentrations
(D) permits release of neurotransmitters when it is bound to adenosine receptors, whereas adenosine inhibits such release
(E) inhibits both neuron firing and the production of phosphodiesterase when there is a sufficient concentration in the brain, whereas adenosine inhibits only neuron firing
2.    According to the passage, the MESBIC approach differs from the SBA approach in that MESBIC’s

(D) They expected that the colonies would offer them increased opportunity.
(E) They were generally not as educated as the people who remained in England.
好了，够了，因为已经能够足以说明问题了。谢谢！

那这里的in that不是正好可以解释产量varies 的这个方面嘛？

至于can和be able to在白勇的书里不是一直强调前者表示可能性，后者表示一种能力。而相同的一块地产量相差很大，是因为一棵树，依赖他的size，climate还有altitude，有可能生产出不同的产量，还是一棵树，依赖他的size，climate还有altitude，有能力生产出不同的产量啊？ 这里我觉得还是can好一点啊？

至于斑竹说的can = to be able to do something or to know how to do something.
can多了一重意思，所以用be able to更好.
那如果这样理解的话，这两个在这里都可以了啊。

aeoluseros

in that和because:
1.
Teratomas are unusual forms of cancer in that they are composed of tissues such as tooth and bone, tissues not normally found in the organ in which the tumor appears.
从他们组成不同组织的角度来看，Teratomas是cancer的unusual forms.

2.
依然是引用：

I've been lucky in that I have never had to worry about money.

我的翻译是：从不缺钱花（的角度），我很幸运。如果我们将 in that 改为because: I've been lucky because I have never had to worry about money. 我不缺钱，所以我很幸运。比较可以发现这两种说法表达的含义不一样，前者是从一个特定角度(in what way) 来解释
           I have been lucky is true；后一种说法暗示钱是be lucky的唯一（或者说全局）决定因素。

3.
The yield per acre of coffee berries varies enormously, because a single tree, depending on both its size and on climate and altitude, is able to produce enough berries to make between one and twelve pounds of dried beans a year.
亩产变化很大，因为一棵树的足量产额为1到12之间。

The yield per acre of coffee berries varies enormously in that a single tree, depending on its size and on climate and altitude, could produce enough berries to make between one and twelve pounds of dried beans a year.
亩产变化很大，从一棵树的足额查呢为1到12之间的角度讲。(不是很合逻辑)
=========================================================================
can和be able to:
这里逻辑上只是说明单科树可以做到产量在1到12之间，并没有要说明树知道如何把自己的enough production固定在1和12之间更大的量上，也就是说，逻辑上也没必要强调这些树达到1到12的产量是需要"know how to do"的。

umm...如果某棵tree很明显地每次经过栽培后都能够达到12的产量，那么就应该用can。

我怎么觉得这个BOTH.. AND用的不好啊。。
难道不是应该BOTH ON .. AND ON么。。

          I have been lucky is true；后一种说法暗示钱是be lucky的唯一（或者说全局）决定因素。

刚开始看前人的这个帖子，还不是很理解，现在觉得悟出点什么了，谢谢版主。再来确认下我的想法吧，上面那个例子，如果用in that，那是不是也暗示造成我lucky的原因有很多，但是这里只是从我不缺钱花的角度来解释我lucky；而如果用because，那么我lucky的唯一原因就是我不缺钱花。

也如版主所说，如果用in that就是只从这一个角度来解释变化大的原因不合逻辑。原文没有这个意思。

can和be able to的问题还是没明白，我再想想。
非常感谢版主


楼上，both on 。。。and on的用法确实是对的，但是像题目中这种形式虽然不如这种对称的那么好，但也是正确的，现在的语法题很少有对称的非常公正的，有很多时候都是有一点小变化了。就像not only，but（also）一样，各种变化层出不穷。在prep和og里面有很多体现。

aeoluseros

umm...这两个都不会成为选项的最终判定规则的。意义的区别过于subtle，必然有其他大错误。
关于can和be able to主要是要理解can比be able to多出"know how to do"这一层含义，pipil再理解一下。

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.

问题在应该用can而不是could varies并不是过去式。。没理由要用could...
depending on both...这个both不清楚指的是那些..both的用法不理想。。。
