In a plausible but speculative scenario, oceanographer Douglas Martinson suggests that temperature increases caused by global warming would not significantly affect the stability of the Antarctic environment, where sea ice forms on the periphery of the continent in the autumn and winter and mostly disappears in the summer. True, less sea ice would form in the winter because global warming would cause temperatures to rise. However, Martinson argues, the effect of a warmer atmosphere may be offset as follows. The formation of sea ice causes the concentration of salt in surface waters to increase; less sea ice would mean a smaller increase in the concentration of salt. Less salty surface waters would be less dense and therefore less likely to sink and stir up deep water. The deep water, with all its stored heat, would rise to the surface at a slower rate. Thus, although the winter sea-ice cover might decrease, the surface waters would remain cold enough so that the decrease would not be excessive.

It can be inferred from the passage that which of the following is true of the surface waters in the current Antarctic environment?
A They are more affected by annual fluctuations in atmospheric temperatures than they would be if they were less salty.
B They are less salty than they would be if global warming were to occur.
C They are more likely to sink and stir up deep waters than they would be if atmospheric temperatures were to increase.
D They are able to offset some of the effects of global warming beyond the Antarctic region.
E They are less affected by the temperature of deep water than they would be if atmospheric temperatures were to increase.

The passage suggests that Martinson believes which of the following about deep waters in the Antarctic region?
A They rise to the surface more quickly than they would if global warming were to occur.
B They store heat that will exacerbate the effects of increases in atmospheric temperatures.
C They would be likely to be significantly warmed by an increase in atmospheric temperatures.
D They would be more salty than they currently are if global warming were to occur.
E They are less likely to be stirred up when surface waters are intensely salty than when surface waters are relatively unsalty.

According to the passage, which of the following is true about the sea ice that surrounds the Antarctic continent?
A The amount of sea ice that forms in the winter has been declining.
B Most of the sea ice that forms in the winter remains intact in the summer.
C Even small changes in the amount of sea ice dramatically affect the temperature of the surface waters.
D Changes in the amount of sea ice due to global warming would significantly affect the stability of the Antarctic environment.
E Changes in the amount of sea ice affect the degree of saltiness of the surface waters.

选项本身比题目更难理解。。三道题都在玩文字游戏的感觉就都贴出来了
答案CAE
第一第二题其实一个道理 第一题C选项They are more likely to sink and stir up deep waters than they would be if atmospheric temperatures were to increase其实意思应该是比起大气温度上升时，它们现在更容易sink and stir up deep waters，换句话说是大气温度上升时它们更不容易stir up deep waters，现在的情况更容易stir up.
但是我觉得换个文章同样的考法我就又看不出来了，甚至理解完第一题，单看第二题的选项的时候又觉得绕晕了，还是没有找到很好的理解方法，望指点。
第三题的A选项是不是错在has been declining？也不是很能理解。

跟楼主情况一样 我今天刚做了这题 看解析时也是看答案看解析看原文再重复这个动作 目前也没找到好办法 只能自己多注意了

第三题 第一个选项错误是因为你说的原因 定位的话第5行 True,less sea ice would form in the winter because global warming would cause temperature to rise. 它说下降是global warming 将会引起的，a说已经下降 所以不对。

对呀 我觉得不找到一个比较通用的办法下次在考场遇到还是会跪。。

第三题我看到有人说是因为开头“In a plausible but speculative scenario”表明了这是一种推测 所以不可以选has been declining.可是我觉得从true那里就不是他推测的内容 只是他推测的过程 中间都是一些大家已经同意的东西 他的理论只是想说明global warming不会导致sea ice大幅减少，所以我觉得这解释也不对

这篇文章虎平都说自己错了一个呢

这个实在是太难了，我看了半天都感觉题目不是很合适，选项选的很纠结，要是ben叔在的话就可以让他来分析一下，关键这是被判为了简单题，米国人的简单题，也是呵呵了

ningningliUID：3564628

第八题的虚拟语气也是没怎么很注意~

Steven73UID：3511309

还是没理解前两道题，求指点，跪谢

Steven73UID：3511309

They are more likely to sink and stir up deep waters than they would be if atmospheric temperatures were to increase.
if应该理解成they would be的，还是整个句子的呢？ 根据答案，应该是理解成they would be的，可是为什么呢？

今天刚开始做官方新体，easy难度，9道里面只对了2道。。。我可以去屎了简直:L这篇文章只对了第三题，呵呵呵呵呵呵

又倒回去看了两遍终于懂了……would是指在发生了if后面的条件时将会出现的情况，之前一直理解错了，题目问的是current。所以气候变暖，会导致深层的水不那么容易上来，所以现在的比起变暖的情况就是更容易。

为什么这么纠结的题会被include在easy!EASY!EASY题目里！:mad！跪了啊....喷血中.......

they are .......than they would be if ......
是个句型的虚拟吗？还是不懂

清醒UID：3658270

这是一个虚拟语气句,主句用的是there are 动词原形,根据意思可知是对将来的虚拟,对将来的虚拟从句谓语可以有3种：1 一般过去式 2 were to 加动词原形 3 should 加动词原形，本题 选项用的 were to + 动词原形
因此，主句中的are likely to be 表示的是 current Antarctic environment 的状态， if后面是条件从句  如果  atmosphere were to increase。
相比而言， current Antarctic environment would be more likely to sink and stir up than if the atmosphere were to increase

清醒UID：3658270

同样 第8题的A选项， 同样是虚拟语气
Deep water in the Antarctic region would rise to the surface more quickly than  if the global warming were to occcur.
