[求助]og-184-解释不明

Across

184. As measured by the Commerce Department, corporate profits peaked in the fourth quarter of 1988 and have slipped since then, as many companies have been unable to pass on higher costs.fficeffice" />

(A) and have slipped since then, as many companies have been unable to pass on higher costs

(B) and have slipped since then, the reason being because many companies have been unable to pass on higher costs

(C) and slipped since then, many companies being unable to pass on higher costs

(D) but, many companies unable to pass on higher costs, they have slipped since then（A）

(E) yet are slipping since then, because many companies were unable to pass on higher costs

A, the best choice, observes an appropriate sequence of verb tenses a single act in the past (peaked) followed by an extended activity reaching to the present (have slipped). The as clause states clearly the cause of the slippage. B suffers from the redundant and unidiomatic expression the reason being because.

In C, the use of the simple past slipped with since then is unidiomatic because since then denotes extended time.

In D, the intrusion of the awkward many... costs causes the antecedent of they to become unclear.

Furthermore, a comma should precede the but since it introduces a second independent clause. –这里好理解, 因为有新的主语many companies出现

In E, yet also requires a comma before it, ---为什么???为什么要在yet前面放逗号??

are slipping with since then is illogical, and were unable represents an ungrammatical tense shift.

下面这个为什么yet前面不用逗号呐??

    

114. From the bark of the paper birch tree the Menomini crafted a canoe about twenty feet long and two feet wide, with small ribs and rails of cedar, which could carry four persons or eight hundred pounds of baggage so light that a person could easily portage it around impeding rapids.

(A) baggage so light

(B) baggage being so light

(C) baggage, yet being so light

(D) baggage, and so light（E）

(E) baggage yet was so light


两个题目的答案没问题. 就是逗号不明白, 求解释, 谢谢谢谢

同样的疑问。而且第一例中，如果yet 前面必须加逗号，一个选项里面的and, 前面也应该加。从语法上讲他们的作用是一样的呀。只是语气不同。

有没有人能回答? 谢谢谢谢

我查了下字典：字典中的例子中yet作连词前面必须加“，”无论平行的是什么成分。我想这点上yet跟and是有区别的。

那为什么114里面没有逗号呐???

jnlvo

我想只能这么理解了：114的yet之所以不加“，”是为了避免歧义。加了“，”yet引导的部分就不知是跟主句，还是跟which后的从句；184就不存在如此情况。我想通常情况下yet前面是要加“，”的。


你的心真细！！！我就少颗细致的心！！！要是考试一定会为此付出代价的喔！！！

Pumpkin MM的问题真好．通过查阅GMAT/LSAT RC, CR，发现ETS对yet的用法有如下：fficeffice" />

Yet adv.

Have not yet.., does not yet…, and yet+动词是常见形式

Which one of the following principles, if valid, most helps to justify the position advocated above and yet places the least restriction on the allocation of funds by directors of charitable organizations?

Yet conj有四种形式

句子．Yet (,)＋句子// 句子；Yet (,)+句子// 句子，yet+句子(只要是完整主谓结构就可以，不必是新的主语)//句子: yet (,)+句子

Pumpkin MM说：In D, the intrusion of the awkward many... costs causes the antecedent of they to become unclear.

Furthermore, a comma should precede the but since it introduces a second independent clause. –这里好理解, 因为有新的主语many companies出现　有不同看法　例如：The great medieval universities had no administrators, yet they endured for centuries.（GMAT/LSAT CR）

Many countries that are large consumers of sugarcane increased their production of sugarcane-based ethanol, yet their overall consumption of sugarcane decreased.

没有查到主语+谓语1+yet+谓语2的例子.ETS好像很少这么用. 这道题目是不是很特殊???

更佩服Jnlvo的解释

好东东！谢谢分享！

偶说的有新的主语出现, 不一定是另外的主语, 只要是出现主语了, 就要有逗号----用来强调另外一个分句. 这个有贴, 讲run-on sentence的.
