标题: prep - 13题救命呀不懂呀

13.(25752-!-item-!-188;#058&002668)

An unusually severe winter occurred in Europe after the continent was blanketed by a blue haze resulting from the eruption of the Laki Volcano in the European republic of Iceland in the summer of 1984.Thus, it is evident that major eruptions cause the atmosphere to become cooler than it would be otherwise.

Which of the following statements, if true, most seriously weakens the argument above?

(A) The cooling effect triggered by volcanic eruptions in 1985 was counteracted by an unusual warming of Pacific waters.

(B) There is a strong statistical link between volcanic eruptions and the severity of the rainy season in India.

(C) A few months after El Chichn's large eruption in April 1982, air temperatures throughout the region remained higher than expected, given the long-term weather trends.（答案）

(D) The climatic effects of major volcanic eruptions can temporarily mask the general warming trend resulting from an excess of carbon dioxide in the atmosphere.

(E) Three months after an early springtime eruption in South America during the late 19th century, sea surface temperatures near the coast began to fall.

1984年夏天的 LV eruption引起蓝霾，那年的冬天奇寒无比。
结论：eruptions引起天气比正常情况下寒冷。

(C) A few months after El Chichn's large eruption in April 1982, air temperatures throughout the region remained higher than expected, given the long-term weather trends.
1982年4月在E eruption爆发后的几个月，从长期的气候趋势看整个区域的气候温度比正常情况下都要高。这显然和结论是相反的。

D 选项错哪里啦

我觉得、、、D：这种eruption带来的气候变化能暂时性的阻挡变暖的趋势，也是支持啊。。。

(D) The climatic effects of major volcanic eruptions can temporarily mask the general warming trend resulting from an excess of carbon dioxide in the atmosphere.
eruption带来的气候效应会暂时掩盖气候转暖的趋势（这种趋势是由大气中过量的二氧化碳引起的）。

这应该是一个无关选项。原结论：eruptions引起天气比正常情况下寒冷。此项只能说明气候的转暖和eruption没有关系，而是另外的因素。因此，即使证明气候是变暖的，也不能削弱原结论。

后半句，，，是说能够暂时性缓解这种由二氧化物。。。的excess 。。造成的变暖趋势。。。

这样看也是无关选项撒

D is in fact a strengthener of the original argument, which claims that major eruptions cause the atmosphere to become cooler than it would be otherwise. It simply provides a reason to explain how an erruption can stop the general WARMING trend for a brief time. So D is not a weakener for the question.

恩这个支持我理解了

哪里有prep的解释啊~~~~之前下的prep都只有题目和答案，木有解释啊

请问NN这道题A选项错在哪里啦？

The conclusion is: it is evident that major eruptions cause the atmosphere to become cooler than it would be otherwise.

A supports this conclusion by confirming that "The cooling effect triggered by volcanic eruptions in 1985 . . ."

要削弱的结论是：eruptions引起天气比正常情况下冷
A说这种冷的效应会被太平热的不正常的水抵消。它并没有反对结论啊，火山爆发还是引起了天气变冷啊。

别老盯着后半句嘛咱看看前半句
单看后半句确实无关，但是句子开头说的是the climatic effects of major volcanic eruptions导致的，也就是说后面的二氧化碳过量并不是凭空出现的，而是由effects造成的所以我认为这并不是无关项

Why a strenghener?
Personally,D is correct as well.
Stimulus:eruptions-->severe winter
D:The climatic effects of major volcanic eruptions mask the general warming(as an another reason)-->severe winter
Therefore,I can accept D.
Please correct me!

同意！

我个人觉得D选项不是一个无关选项，其实D选项是个加强原文的选项因为说可以阻挡变暖的趋势，所以是在加强文章观点。所以错误。

It mentioned THE COOLING EFFECT. It actually strengthen the argument by admitting the cooling effect.
