我我我竟不懂split是什么意思，但感觉SC不算简单，比较模棱两可，没有那么快能够选出来 记得有一题两个选项区别：latest forthcoming/ forthcoming latest 就感觉考点比较细（天哪，我竟然能够回忆起来 amazing）

楼主～你说的那个阅读 我有找到类似的文章～求鉴别一下是不是～感觉和你说的思路还是很相似的～
Isn't the earth actually warming? Indeed it is, says Joyce. ' In his cluttered office, full of soft light from the foggy Cape Cod morning, he explains how such warming could actually be the surprising culprit of the next mini-ice age. The paradox is a result of the appearance over the past 30 years in the North Atlantic of huge rivers of fresh water - the equivalent of a 10-foot-thick layer - mixed into the salty sea. No one is certain where the fresh torrents are coming from, but a prime suspect is melting Arctic ice, caused by a build-up of carbon dioxide in the atmosphere that traps solar energy.
The freshwater trend is major news in ocean-science circles. Bob Dickson, a Brit¬ish oceanographer who sounded an alarm at a February conference in Honolulu, has termed the drop in salinity and temperature in the Labrador Sea - a body of water between northeastern Canada and Greenland that adjoins the Atlantic - "arguably the largest full-depth changes observed in the modern instrumental oceanographic record".
The trend could cause a little ice age by subverting the northern penetration of Gulf Stream waters. Normally, the Gulf Stream, laden with heat soaked up in the tropics, meanders up the east coasts of the United States and Canada. As it flows northward, the stream surrenders heat to the air. Because the prevailing North Atlantic winds blow eastward, a lot of the heat wafts to Europe. That's why many scientists believe winter temperatures on the Continent are as much as 36 de¬grees Fahrenheit warmer than those in North America at the same latitude. Frigid Boston, for example, lies at almost precisely the same latitude as balmy Rome. And some scientists say the heat also warms Americans and Canadians. "It's a real mistake to think of this solely as a European phenomenon," says Joyce.
Having given up its heat to the air, the now-cooler water becomes denser and sinks into the North Atlantic by a mile or more in a process oceanographers call thermohaline circulation. This massive column of cascading cold is the main engine powering a deep-water current called the Great Ocean Conveyor that snakes through all the world's oceans. But as the North Atlantic fills with fresh water, it grows less dense, making the waters carried northward by the Gulf Stream less able to sink. The new mass of relatively fresh water sits on top of the ocean like a big thermal blanket, threatening the thermohaline circulation. That in turn could make the Gulf Stream slow or veer southward. At some point, the whole system could simply shut down, and do so quickly. "There is increasing evidence that we are getting closer to a transition point, from which we can jump to a new state."

Switching to electric cars will not improve the environment, despite the fact that such cars produce no harmful emissions. The electricity to run them world still need to be generated from power plants, the majority of which burn such fossil fuels as coal, oil and natural gas. Any reduction in fossil fuel demand at gas stations resulting from the replacement of internal combustion engines with electric ones would be reversed by a commensurate demand for more energy from our nation’s power plants.

Which of the following, if true, would most weaken the above argument?

A. The nation’s power grid would need a massive restructuring if it is to generate the energy needed to power vehicles that run on electicity.
B. Electric vehicles are significantly more energy-efficient than their gasoline powered counterparts.
C. Coal is a far less environmentally-friendly way to generate energy than is natural gas.
D. Studies indicate that most drivers would be reluctant to switch from gasoline –powered to electric vehicles.
E. Hybrid vehicles offer a more practical short-term alternative than do vehicles that run solely on electricity.
我在外网上挖出来的。。逻辑推理这个是原题么

我也不知道 只挖出来题干没挖出来答案
有人说选B  感觉怪怪的
等下楼主和逻辑君回复吧

好吧我也选B，因为好像其它选项就根本没相关了。然后如果针对argument的话，就是题干的第一句话。所以看来看去能削弱第一句话的选项只有B了。期待大牛来分析
