问一道9月15日阅读题，cloud system

vngogherUID: 3391684

As of the late 1980’s, neither theorists nor large-scale computer climate models could accurately predict whether cloud systems would help or hurt a warming globe. Some studies suggested that a four percent increase in stratocumulus clouds over the ocean could compensate for a doubling in atmospheric carbon dioxide, preventing a potentially disastrous planetwide temperature increase. On the other hand, an increase in cirrus clouds could increase global warming.
That clouds represented the weakest element in climate models was illustrated by a study of fourteen such models. Comparing climate forecasts for a world with double the current amount of carbon dioxide, researchers found that the models agreed quite well if clouds were not included. But when clouds were incorporated, a wide range of forecasts was produced. With such discrepancies plaguing the models, scientists could not easily predict how quickly the world’s climate would change, nor could they tell which regions would face dustier droughts or deadlier monsoons.


25. It can be inferred that one reason the fourteen models described in the passage failed to agree was that
(A) they failed to incorporate the most up-to-date information about the effect of clouds on climate
(B) they were based on faulty information about factors other than clouds that affect climate
(C) they were based on different assumptions about the overall effects of clouds on climate
(D) their originators disagreed about the kinds of forecasts the models should provide
(E) their originators disagreed about the factors other than clouds that should be included in the models


答案是C，但是我到现在都没看出来文中哪儿指出
they were based on different assumptions about the overall effects of clouds on climate 了？？？难道是最后半句dustier droughts or deadlier monsoons??
这篇文章我也觉得很怪，主要是第二段。一般来说首句都很重要，第二段首句说clouds represented the weakest elements. 后面又说加入云以后所有的模型都不一致了，尼玛那这首句是啥子意思。

还有我分析发现OG和PP2里的题目和答案一般都是围绕文章主旨的，很少有和文章主旨无关的细节题，可这篇就是来了这么一道：

26. It can be inferred that the primary purpose of the models included in the study discussed in the second paragraph of the passage was to
(A) predict future changes in the world’s climate
(B) predict the effects of cloud systems on the world’s climate
(C) find a way to prevent a disastrous planetwide temperature increase
(D) assess the percentage of the Earth’s surface covered by cloud systems
(E) estimate by how much the amount of carbon dioxide in the Earth’s atmosphere will increase
答案是A，是和文章主旨没啥关系啊。。。

那篇女权运动的长阅读加这篇我阅读史里的离群值， 让我这个模考156- 162的人最后落得个150. 至今还在心如刀绞，如今切实体会到什么叫绝对的绝望，什么叫求生不得求死不能。

这句话啊

Comparing climate forecasts for a world with double the current amount of carbon dioxide, researchers found that the models agreed quite well if clouds were not included.

这句话是说有些人include cloud, but some may not, 于是对于models的assumption就不一样。

26是考一个段落的作用啊。
这明显是和主旨有关的。
这篇讲的是cloud对于全球变暖的作用
compensate for the heating effect.
但是第二段指出cloud对于prediction model的消极影响——导致model无法准确预测。

这句话啊

有些人include cloud,有些人may not?
他后面是说But when clouds were incorporated, a wide range of forecasts was produced. 这说的应该就是全部没有include的时候一致，然后全部都include 的时候不一致吧，，

这句话啊

还有答案说的是assumptions about the overall effects of clouds ，并不是对model的assumption

第一段说，有时候这种云的影响显著会如何如何，又说有时候那种云的影响显著会如何如何。当然是基于不同的假设了，模型之所以不一样完全在于他们的假设的不同，因为只要是同一个学科，内在的逻辑肯定是一致的。

我说的对于model的assumption是指include和不include造成的数据问题。
而这个assumption就是cloud overall effect
你quote的那句话，他说当include了以后，出现了wide range， why?
你有想过吗？因为predict的结果不同了
why？
因为不同人对overall effect理解不同了。
理解不同才会导致结果不同

这是考试的题目？怎么弄到的啊？

恩，这题我觉得只能用排除法了。。

你除了知道为什么某个选项是错的，还需要知道为什么某个选项是对的。
这才是对待阅读理解正确的态度

恩，对于这样文章里没有直接的答案的infer题，自身水平还是有限。

刚好还没做到，像这样的老题在新G里面出现得多吗？

老题啊

吴中东的第26题答案是B啊！不过我刚自己做的时候也选A。考试的时候也是这题吗？那就得求证答案哪个是对的了。
