这道题我想了好久，绕来绕去才有了上面的解释（还不知道对不对），白白姐解释得清清楚楚。

不愧是CR NN! 赞一个！

以下是引用文明在2007-10-9 22:07:00的发言：

Q40: Insect infestations in certain cotton-growing regions of the world have caused dramatic increases in the price of cotton on the world market. By contrast, the price of soybeans has long remained stable. Knowing that cotton plants mature quickly, many soybean growers in Ortovia plan to cease growing soybeans and begin raising cotton instead, thereby taking advantage of the high price of cotton to increase their income significantly, at least over the next several years.

Which of the following, if true, most seriously weakens the plan’s chances for success?

B. Tests of a newly developed, inexpensive pesticide have shown it to be both environmentally safe and effective against the insects that have infested cotton crops.

D. Few consumers would be willing to pay significantly higher prices for cotton goods than they are now paying.

本来没做到那么后的GWD，看见大家讨论的热情高涨，我也来参与一下（我没太多挣扎就选了B，洋洋，你把B和D手误输反了吧？）：

宝儿，你在那边帖子讲的“现在的价格”我理解是“虫害正在发生的现在的价格”，原文的过去完成时就是从之前某个时间发生并持续到现在的呀。

简化原文信息之后基本上种豆的内容可以忽略，逻辑链：【因：虫害；果：棉花价格上升；结论：人们跑去种棉花】

（B）虫害受控，切断因，则棉花价格上升的果就被破坏【是逻辑削弱题型的一种典型——切断因果】

（如果从供求关系来看，多了人去种棉花+而原来种棉花的因为没有虫害=＝＝》产量暴增＝＝＝》价格暴跌）

（D）貌似有供无求＝＝＝》新棉农就亏大了，但是忘记了原文讲到“多了很多人去种棉花”，但是因为虫害嘛，所以产量不会暴增，但是总会稍微比少人种的情形增加一些，因此价格不会继续上涨，反而会适当下调，这样人们不会面对过高的价格，“有供无求”的局面不太有坚强立场

万一是they are now paying,然后have caused （表示和now的情况发生过了变化）呢？

另外D：many不一定使significant higher不成立呀，万一有虫害以后价格涨得很高呢

GMAT经常考到商业中的供应与需求决定赢利的问题

最后一个B致命的错误：从哪里可以看出农民会用这种杀虫农药的？也许他们为了使价格继续保持升高，就不会用呢？或者只用于保留一小快地用这种农药来生产健康的棉花拿去市场卖高价？

另外OG里一般出现这种新的名词都是无关

哎，不知道了，觉得B也开始有点点对了呵呵

宝儿

用不用农药是个常识问题啦，就跟出口会拉动需求一样

我不太明白你表达的意思

我能表达的就是D 说了没有几个人会愿意负更高的价钱去买棉花物品（COTTON GOODS)

这个和将来种棉花会不会赚钱没有任何关系的

姐妹们，好久没露面了，有个问题，今天突然很想不通，到底什么是run－on结构啊？

我一直的理解是一个句子里有两套主谓结构，就是run-on，这种结构是错的，今天看到一个句子：A is B and C（is被省略）D，我彻底晕掉，难道是我对run-on的理解错误？

高手们好好给我讲讲啊！

今天效率不怎么样,上午不知道在干嘛....哦,有做好吃的..倒掉!

下午睡了一大觉.....更晕了...

晚上干嘛了??好像看了咖啡王子最后一集.....彻底昏掉....

结果不要说SC,RC了,连GWD分类的ASSUMPTION都没搞定.....

明天开始我要发奋图强了...奶奶的...

哎.先看条CR吧.搞不定了.白白姐姐来帮忙~~

Lawmaker: Raising taxes is not the only means of reducing government debt. The government’s stockpile of helium is worth 25 percent more, at current market prices, than the debt accumulated in acquiring and storing it. Therefore, by selling the helium, the government can not only pay off that debt but reduce its overall debt as well.

 

Which of the following is an assumption on which the argument depends?

A.     The government has no current need for helium

B.     Twenty-five percent of the debt the government has accumulated in Stockpiling helium is not an insignificant portion of the government’s Total debt.

C.      It is not in the lawmaker’s interest to advocate raising taxes as a Means of reducing government debt.

D.     Attempts to sell the government’s helium will not depress the market Price of helium by more than 25 percent

E.      The government will not incur any costs in closing its facilities for stockpiling helium.

我选的是B,但是答案是D,目前D呢,我已经很清楚了,只是B,我觉得它也对啊.它取非不就是说25%的DEBT对政府不重要吗?那么不重要的话,卖掉也没啥用啊.不是WEAKEN了吗????

RUN-ON就是:

Run-On Sentence (choice A)

A RUN-ON SENTENCE (sometimes called a "fused sentence") has at least two parts, either one of which can stand by itself (in other words, two independent clauses), but the two parts have been smooshed together instead of being properly connected. Review, also, the section which describes Things That Can Happen Between Two Independent Clauses.

It is important to realize that the length of a sentence really has nothing to do with whether a sentence is a run-on or not; being a run-on is a structural flaw that can plague even a very short sentence:

The sun is high, put on some sunblock.

An extremely long sentence, on the other hand, might be a "run-off-at-the-mouth" sentence, but it can be otherwise sound, structurally.

When two independent clauses are connected by only a comma, they constitute a run-on sentence that is called a comma-splice. The example just above (about the sunscreen) is a comma-splice. When you use a comma to connect two independent clauses, it must be accompanied by a little conjunction (and, but, for, nor, yet, or, so).
     

The sun is high, so put on some sunscreen. (逗号前后的两个句子必须有连词)

Run-on sentences happen typically under the following circumstances*:

a.
      When an independent clause gives an order or directive based on what was said in the prior independent clause:

This next chapter has a lot of difficult information in it, you should start studying right away.

(We could put a period where that comma is and start a new sentence. A semicolon might also work there.)

b.
      When two independent clauses are connected by a transitional expression (conjunctive adverb) such as however, moreover, nevertheless.
     

Mr. Nguyen has sent his four children to ivy-league colleges, however, he has sacrificed his health working day and night in that dusty bakery.

(Again, where that first comma appears, we could have used either a period — and started a new sentence — or a semicolon.)

c.
      When the second of two independent clauses contains a pronoun that connects it to the first independent clause.
     

This computer doesn't make sense to me, it came without a manual.

(Although these two clauses are quite brief, and the ideas are closely related, this is a run-on sentence. We need a period where that comma now stands.)

Most of those computers in the Learning
     Assistance
     Center are broken already, this proves my point about American computer manufacturers.

Again, two nicely related clauses, incorrectly connected — a run-on. Use a period to cure this sentence.

那么也就是说:

一个 Run-On Sentence 至少包含两个独立子句 (independent clauses)，但它们没有被适当地连接起来。

　

1.	句子的长短实际上与句子是否 run-on 无关；run-on 的句子是属于句子结构的瑕疵、错误，即使非常简短的句子亦将受到危害。 The sun is high, put on some sun-block.
2.	当两个独立子句仅用一个逗点来连接时，它们就构成所谓 comma-splice or comma fault (用逗点分开两个对等子句的错误) 的 run-on sentence。上面的例子就是 comma-splice。当你用逗点来分开两个独立子句时，逗点的后面必须接 and, but, for, nor, yet, or, so 等连接词。 The sun is high, so put on some sun-screen.
3.	run-on sentences 通常发生在下列情况下：
	a.	当一个独立子句根据前一个独立子句所说的而下达命令或指令时： This next chapter has a lot of difficult information in it, you should start   studying right away. 我们可以将这个句子中的逗点改为句点 (· period) 然后开始一个新的句子或改为分号 (；semicolon)。
	b.	当两个独立子句使用 however, moreover, nevertheless 等连接副词 (conjunctive adverbs) 来连接时： Mr. Nguyen has sent his four children to ivy-league colleges, however, he  has sacrificed his health working day and night in that dusty bakery. 同样地，第一个逗点应改为句点，然后开始一个新的句子，或改为分号 。
	c.	当两个独立子句中的第二个子句包含一个代表第一个独立子句的代名词时： This computer doesn't make sense to me, it came without a manual. 虽然这两个子句相当简短，而且关系相当密切，但却是个 run-on sentence。我们必须以句点来取代逗点。

这样的解释,宝宝清楚了吗?

天啊...恐怖的论坛.....居然搞出这么可怕的排版....真是要命...

大洋彼岸369

求教:

Shoppers in sporting goods stores, unlike in department stores, do very little impulse shopping, not buying a pair of skis and a boomerang when they come in for a basketball, but they leave with a basketball only.

 

A.        in department stores, do very little impulse shopping, not buying a pair of skis and a boomerang when they come in for a basketball, but they leave with a basketball only

B.        in department stores, shop impulsively very little; someone who comes in for a basketball will leave with a basketball only and not also buy a pair of skis and a boomerang as well

C.       those in department stores, do very little impulse shopping, do not buy a pair of skis and a boomerang when they come in for a basketball, but leave with only a basketball

D.       those in department stores, do very little impulse shopping; someone who comes in for a basketball will leave with a basketball only and not buy a pair of skis and a boomerang as well

E.        department stores, shop impulsively very little; someone will not buy a pair of skis and a boomerang when they come in for a basketball but will leave with only a basketball

 

对答案D在这道题目里没有疑问, 但是如果再有这么个选项: those in department stores, do very little impulse shopping; someone who comes in for a basketball will leave with a basketball only and not buy a pair of skis and a boomerang. 我想我会选这个, 因为感觉D项中的最后"as well" 冗余, 姐妹们多指教哈.

对了, 感觉白白好N啊, 肯定是我们这里即将诞生的超级NN, 期待ing.
