今天做白皮书遇到了一篇特别呵呵的文章，几乎全错，但是我来来回回的读了好几遍真的不觉得我选错了，求大神给解析
As of (As of: 到...时为止;从...时起) 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 (stratocumulus: n.[气]层积云) 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 (cirrus: n. 〈气〉卷云) 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.
　　24. The author of the passage is primarily concerned with
　　(A) confirming a theory
　　(B) supporting a statement
　　(C) presenting new information
　　(D) predicting future discoveries
　　(E) reconciling discrepant findings
　　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
　　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
　　27. The information in the passage suggests that scientists would have to answer which of the following questions in order to predict the effect of clouds on the warming of the globe?
　　(A) What kinds of cloud systems will form over the Earth?
　　(B) How can cloud systems be encouraged to form over the ocean?
　　(C) What are the causes of the projected planetwide temperature increase?
　　(D) What proportion of cloud systems are currently composed of cirrus of clouds?
　　(E) What proportion of the clouds in the atmosphere form over land masses?

他给的答案是BCAA
个人认为是CBBD
全错的节奏…真心求解析了！题海战术不好好归纳总结跟没做题一样，求讨论！

1.As of (As of: 到...时为止;从...时起) 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.
全文都在支持这个观点，所以选B
2.Some studies suggested that a four percent increase in stratocumulus (stratocumulus: n.[气]层积云) 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 (cirrus: n. 〈气〉卷云) clouds could increase global warming.
按照两种产生不同效果的云，得不出精确结果，而不是没有其他不是云的因素
3.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.
所有的模型都是为了预测未来天气情况，但因为不知云是 help or hurt a warming globe。所有预测不准。
4.文章并没说只有两种云，只是有这两种效果不同，如果我们知道整个云层的组成成分，就可以知道整体效果。所有是A

多谢解析！！ 第一题我还有一点没理解！

全文都在支持这个观点，所以选B
全文都在支持哪个观点…我感觉第一段只是介绍了两种不同的观点（s云和c云），然后第二段进一步分析其他观点（有云和没云）

第一句说不论是理论还是模型都不能准确定位云层是有利于还是不利于warming globe。这就是全文的观点

但是我感觉还是很像两个观点的比较……或者说我感觉作者自己没什么观点
