700以上是我们共同的目标，刨根问底是必要条件

Nature constantly adjusts the atmospheric carbon level. An increase in the level causes the atmosphere to hold more heat, which causes more water to evaporate from the oceans, which causes increased rain. Rain washes some carbon from the air into the oceans, where it eventually becomes part of the seabed. A decrease in atmosphere carbon causes decreased evaporation from the oceans, which cause less rain, and thus less carbon is washed into the oceans. Yet some environmentalists worry that burning fossil fuels may raise atmospheric carbon to a dangerous level. It is true that a sustained increase would threaten human life. But the environmentalists should relax---nature will continually adjust the carbon level.

 

132. Each of the following can be inferred from the information in the passage EXCEPT:

 

A.        A decrease in the level of atmospheric heat causes a decrease in the amount of carbon that rain washes into the oceans from the air.

B.        An increase in the level of carbon in the atmosphere causes increased evaporation of ocean water.

C.        An increase in the level of atmospheric heat causes increased rainfall.

D.       A decrease in the level of carbon in the atmosphere causes decreased evaporation of ocean water.

E.        A decrease in the level of atmospheric heat causes a decrease in the level of carbon in the atmosphere.  为什么？？？

An increase in the level of carbon à more heatà more water to evaporate from the oceansà increased rainà washes more carbon from the air into the oceansà becomes part of the seabed

没有问题

但是

A decrease in atmosphere carbonàless heatà decreased evaporation from the oceansàless rainà washes less carbon from the air into the oceans

为什么选e 阿，明明是原文的逆否命题阿！！！！！！！！

我做了４套GWD了
昨天做第３套的时候错到１０个以下，高兴坏了
结果今天又错了１２个，其中SC：CR：RC＝６：４：２（汗，等差数列）

怎么办怎么办，SC怎么办，CR怎么办，CR是很久没做了错这么多情有可原，可是我最近SC大全一直都在做啊，也看了BY了，为什么还是错这么多啊

春衫如雪

各位老大跑得好快啊，我得狂追了~~~~

这题绕人。E选项错在逆否命题无依据。
题目开头:  大气中含碳量高—>大气含热量增高，反推是不正确的，难道大气含热量高就说明大气含碳量高吗？没有依据可推出。

文章里压根就没充要关系，逆否不成立。Lawyer有篇文章将充要关系的，搜以下，在CR区。

顾风：看了你46天计划，基本安排做taotao,你是怎样比较taotao31套和xy13的。我也准备过两天开始做，但不知道选那一种，矛盾啊？

你看离考试时间有多少天吧，时间多就做taotao，时间少就做xy13吧。

老兄好好分析一下E，问个问题，是先有鸡还是先有蛋？

多看gwd讨论吧，能比较大的提高，我感觉。。。

友情提醒大家一下，讨论题目时，如果能把题目发到相应的版面，然后把链接粘贴过来效果可能会更好一些，原因有三：

1。发到其它版面能得到队友以外的回复。

2。在本贴下给链接回复会更及时一些(自己的经验判断)

3。我们的讨论也能更多的惠及其他考友。
