大哥大姐们 帮忙看两个选项1马上考试了

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？

我觉得最大的错误是could吧 为啥要用could呢？

二丫丫

used after a statement to begin to explain in what way it is true 。也就是说它是来解释某一情况为什么是真实的，可以理解为“表现在”。I've been lucky in that I have never had to worry about money.而because更多的是强调一种因果关系。而in that则不一定。换到上面的例子里来说，也就是说，如果用in that的话，是我很幸运，因为我从来不用为钱担心。不用为钱担心解释了lucky这件事情。而如果用because的话，则成了因果关系，即不用为钱担心导致我很幸运，这显然在逻辑上是行不通的~
对照此题来讲，这里显然更强调的是一种因果关系，是single tree可以produce巴拉巴拉造成了前半句所说的那种情况。如果用in that的话，就成了咖啡的年产量变化很大，表现在……。这跟用because表达的完全是两个意思。

103.    (29869-!-item-!-188;#058&004446)

The parachutelike membranes of Africa's scaly-tailed flying squirrels differ from those of the flying squirrels in the family Sciuridae because they are attached to a cartilage rod at the elbow instead of the wrist.

(A) because they are attached to a cartilage rod at the elbow instead of
(B) because of being attached to a cartilage rod at the elbow rather than at
(C) in their attachment to a cartilage rod at the elbow instead of being attached at
(D) in that they are attached to a cartilage rod at the elbow rather than at
(E) in their being attached to a cartilage rod at the elbow instead of
又错了。。。虽然是因为马虎没有看到A没有at，但是我想问的是 这里用的in that而没有用because是因为，原文想从parachutelike membranes不同的角度来解释这两种松鼠的不同是吗？如果A加上at没有了比较歧义，也不对是吗？

以前还真没注意过 can和be able to do 这么细过，谢谢！恩，时态还真没注意，光想那些相对性错误了。把最直接的绝对性错误忽略了。

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。。。

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。

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。

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。


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)
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。

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。。

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。
