Industrial emissions of sulfur dioxide (SO2) impede cloud formation, lowering temperatures in regions with high SO2 emissions. Computer modeling suggests that beginning about 1950, the climate of North America and Europe cooled because of SO2 emissions there, and that this cooling in turn caused the tropical rain belt to move southward, away from Africa’s Sahel region. Therefore, industrial emissions in Europe and North America were probably a major cause of the severe Sahel droughts of the 1970s and 1980s.
Which of the following, if true, most strongly supports the position argued in the passage?

(A) During the 1970s and 1980s, industrial SO2 emissions increased rapidly in East Asia.
(B) The effects of the Sahel drought on the local food supply were exacerbated by overgrazing of pasture that could recover less quickly in the arid conditions.
(C) The Sahel region is subject to a natural cycle of droughts, with which the severe Sahel droughts of the 1970s and 1980s coincided.
(D) Since 1950, many of the industrial emissions in North America and Europe have been of substances other than SO2 that tend to cause temperatures to increase.
(E) Rainfall in the Sahel increased following a decline in North American SO2 emissions that began in the late 1980s.

Much of the materials in landfills is paper and other organic materials that decompose gradually. Since these materials decompose much faster when wet, keeping landfills wet would free up space in them faster, thereby both reducing the need for new landfills and slowing expansion of existing landfills. Northwest Environmental Commission is considering a proposal to install watering systems in landfills with the aim of reducing the landfills’ adverse environmental impact on the region.

Which of the following, if true, most strongly supports the prediction that the proposal, if adopted, will not have the intended effect?

A Organic material that is kept wet decomposes even faster, if it is also kept warm.

B Installing watering systems in landfills would add significantly to the costs of landfill management.

C Keeping landfills wet increases the risk that polluted water will leak out into streams, rivers, and lakes.

D Paper and cardboard that are wet are more easily compressed and therefore take up less space.

E Some of the material in landfills do not decompose more rapidly when exposed to moisture.

1.E  2.E
提个想法：能否把题目中相连的两个单词断开，每次看到这里都会卡一下，再往后看

1.strengthen题
（背景：SO2会降低气温）（可忽略）
前提：N和E，SO2排放→降低气温→热带下雨带南移，远离S
结论：S干旱就是因为N和E的排放

2.weaken题
（背景：埋在地里的有机材料，分解慢）（可忽略）
前提：湿的分解加快→减少占地，
结论/提议：加水，使分解加快

看到答案后，自己认为的解析：
第二题：仍然是weaken题（这个要读清楚）
题眼在于“environmental impact”，C符合
E.some=管综的逻辑学“有的”不影响，常考点

SO2会损坏云的formation 降低温度 模型显示1950年起NA和E的气候因为SO2低，并且影响了热带雨林带往南院里A 因此工业排放是S1970-1080严重干旱的主要原因 找增强 E
A 说East Asia SO2排放量上升 无关       
B 讨论的内容不对 讲干旱的影响 要增强结论要找干旱的原因是SO2       
C natural cycle of drought 找了他因和SO2无关 削弱了       
D 1950许多除了SO2的许多工业排放都使得气候变暖了 那就没有cooling effect 削弱了       
E NA SO2排放减少以后 S的rainfall就上升了 明确显示了rainfall和NA的SO2有关 增强       


许多Landfill是paper和其他有机物质很快decompose 因为越潮湿D越快，所以让landfill保持潮湿好 所以NEC决定安装水系统来降低landfills不好的坏境影响 问题是削弱 C
A wet+warm 会decompose更快 但是单独wet也能提高decompose的速度 对环境影响好       
B 会加cost 无关要考虑对环境的影响       
C 容易导致污水泄漏环境 那对环境会有adverse impact 计划无效
D paper和cardboard wet更容易compressed 占用空间少 无关选项 问是否可以减少环境污染               
E 一些不行 most可以就能减少环境污染

1.E （强加因果，补GAP才可加强）
P：二氧化硫排放阻碍云层形成、降低温度。计算机模型显示欧美气候因为二氧化硫而变冷，变冷使雨带南移形成干旱。
C：欧美工业排放极有可能是1970-1980年S地区严重干旱的主要原因
G：加强-原因论证
A：与增长快慢无关；B：问原因，与已发生的影响无关；C：说是自然发生，他因削弱。D：与除了so2的东西无关

2.C
P：垃圾填埋大部分都是纸，其他有机物可逐渐自然降解。因为当潮湿的条件这些物质可以降解的更快，
C：所以保持湿度可以加速填埋土地的空置率；既能降低对新地的需求，又能减缓现存土地空间的使用扩张。
目的：降低土地填埋的负面环境影响。手段：安装水利系统灌溉加湿
G：方案达不到目的
A：无关怎么样做更能促进目标的达成；B：无关方案所消耗的成本多少；D：个体情况无法解释整体；E：局部例子反前提无关。
