prep07上关于/ V-ING 用法/ 夹心修饰与08解释的矛盾之处。

单调唱

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

关于夹心修饰 (by aeoluseros)：
所以歧义修饰，是因为引发了不同的理解，而并不是语法上是否会有不同的修饰，所谓夹心修饰也是这
个原则。很多人对“夹心修饰”都有过一个误解，认为S, v-ing, V. + O.结构中，v-ing既可以往前修饰S，
也可以往后修饰V就是夹心，而实际上夹心并不是“可以往前修饰S，也可以往后修饰V” 。在S, v-ing, V. +
O.这样的表达中，v-ing约定俗成只伴随修饰动词，见下例：
prep 2-104 The yield per acre of coffee berries varies enormously, because a single tree, depending
on 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.
这个句子里depending不能改为dependent，因为depending和dependent的区别在于，前者伴随修饰谓
语动词is able to produce，后者则是修饰名词single tree，会造成逻辑上不对—— “一棵树依靠它的size”。

prep07里说depending作为伴随状语和dependent作为形容词插入语都是合理的用法。

我有点不懂prep08的解释，depending伴随修饰谓语动词is able to produce, 那么它的逻辑主语不还是single tree么，不还是有这个意思“一棵树依靠它的size”。而且我觉得这样的逻辑意思也没什么问题，Depending on it's size, the tree.....逻辑有什么问题？

还有，B和C如何区分？？？好像B,C都是对的啊？？？

泾渭不凡

B和C，从in that和because的角度出发判断~

这题，饭饭就是一看in that表示原因这里不合适啊，没有从某一个角度出发，并且太过正式咯吧，就con掉咯~~

============================================
不过V-ing修饰这儿....
如果前面是主系表结构，由于系动词是一个状态不存在“被伴随”，但是V-ing结构依然修饰的是整个主系表结构，所以后面的V-ing结构也可以被解读为修饰前面的名词成分—主语（如果宾语是名词，也一同修饰，因为主系表结构中主语和宾语所指是同一事物--见OG10-39, OG11-24中对正确选项C的解释）。

例：OG10-39For members of the seventeenth-century Ashanti nation in Africa, animal-hide shields with wooden frames were essential items of military equipment, a method to protect warriors against enemy arrows and spears.

A.a method to protect

B.as a method protecting

C.protecting

D.as a protection of

E.to protect

OG10-39的解释（注意C选项的解释）：

Choice C is best because the participle protecting begins a phrase that explains what the shields did. Choices A and B awkwardly use the singular word method to refer to items of military equipment rather than to the use of such items. Also, a method of protecting would be more idiomatic than a method to protect in A or a method protecting in B. In B and D, as is incorrect; also, a protection in D has no noun for which it can logically substitute. Choice E is incomplete; used to protect would have been acceptable.

OG11-24的解释（注意C和E选项的解释）

Logical predication + rhetorical construction

The underlined part of the sentence begins a phrase describing items of military equipment. It is awkward and inaccurate to describe items as a method. Replacing the underlined phrase with the participle protecting creates a modifying phrase that clearly explains the purpose of the items of military equipment.

AA method to protect is an awkward reference to items

BThe singular a method should not refer to the plural items, as a method protecting is not idiomatic

CCorrect. In this sentence, protecting properly introduces a modifying phrase revealing the purpose of the items.

DBeginning the phrase with as is incorrect; using the noun form protection creates wordiness

EThe infinitive to protect cannot act as an adjective modifying items; the participial form of the verb, protecting, is required

The correct answer is C.

谢谢饭饭~~ 真棒~
oreo是奥利奥咩？

@lz: 那么换个表达
用dependent时："取决/依靠于size的一棵树能够长出足够的浆果"。
用depending时，“一棵树取决它的size来做到长出足够的浆果”。
这样写区别可能就明显一些了
