标题: [求助]og-184-解释不明

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

(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

(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。

up.

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???

作者: jnlvo 时间: 2004-3-26 13:29
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：ffice

ffice" />

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

这个例子更好看: 一般偶们都说, and前面有逗号, 为了分开两个分句.

blablabla sb does sth, and sb does sth.

但是这个:
og207. In the textbook publishing business, the second quarter is historically weak, because revenues are low and marketing expenses are high as companies prepare for the coming school year.fficeffice" />

(A) low and marketing expenses are high as companies prepare

(B) low and their marketing expenses are high as they prepare

(D) low, while marketing expenses are higher to prepare

(E) low, while their marketing expenses are higher in preparation

为了避免, and marketing expenses are high as companies prepare脱离because的笼罩,

所以就不得不取消逗号-一切为了大骨架结构的完美对称和意思的完美平行......

         再次严重感谢jnlvo和pumpkin：刚才写了份作文，正好用这个知识点，感觉很爽

         ..., one can readily arrive the conclusion that advertisements can tell us about a nation's ideas yet    do not necessarily present all aspects of a nation's attitudes.

         习惯的，我想在yet前加上逗号，但是想了想，如果加逗号，那是否割裂了that从句的内容了，于是马上就联想到今天这个知识点，果断的将逗号去掉。。。

         （严重感谢）

         我也5月考，有一阵不怎么碰语法，感觉有点陌生了。以后大家多讨论

好ETS的句子啊......
8过, 两个CAN连用, 能不能改改??
one can readily arrive the conclusion that advertisements tend to tell us about a nation's ideas yet can not present all aspects of a nation's attitudes

8过意思8晓得对不对了...别骂偶乱写啊.呵呵呵

pumpkin的问题和jnlvo的解答让我明白了一个久未搞清楚的问题，这一题我做错了，这个逗号就是我做错的一个判据。当时这个问题没搞清楚，我标了一个openpoint在这个题目旁边,但忘了问了。Now it is closed. Thanks

我也是。看了ETS的解释后还自以为是的做了个总结说：关于这个逗号的问题，只要不出现新主语，有没有都没关系。就把这个问题过掉了。没想到一个小小的逗号还学问不小呀。谢谢pumpkin MM。

同时也感谢dreadpower. 这种问题我们在作文中都会常犯呀。

关于这个问题的最新解释，2个T可以并在一块了。。。。。。。。

作者: 行缘 时间: 2006-3-6 18:19

我比较笨，觉得还是没清楚,是不是:

1.and 和 yet规则相同

2.如果and/yet后面没有主语，则加不加语法上都可以，但要根据句意连贯和是否需要强调考虑．

3.如果and/yet后面有主语，则必须加，但上面举的because的例子就可以特殊吗？

Thank you for your message concerning question 184 in the Sentence

Correction section of The Official Guide for GMAT Review. You indicated that

you were confused by the explanation for why option (E) is incorrect.

The explanation does contain an error; while a comma before "yet" might be

added for emphasis, it is not required because, as you point out, "yet are

slipping since then" is not an independent clause. The rest of the

explanation does accurately describe the grammatical and rhetorical problems

with option (E).

Again, thank you for taking the time to point out this error. We are always

grateful to receive inquiries such as yours because they help us to improve

the quality of our tests and test preparation materials.
