题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.

D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.

According to scientists at the University of Alaska, while the surface temperature of the globe has risen over the last century by about one degree Fahrenheit, the surface temperature in Alaska, Siberia, and northwestern Canada has increased in the previous thirty years by about five degrees.
我听了录音，英老师一来就读出了两句有一致性，所以干掉cde,留AB，b又比a更一致就选了b。 可是我不是这样的，我认为前面说了the surface temperature,后面又没有发生什么变化，为什么不能用it，就代替了？剩de,d时态没对，就选了。

Those skeptical of the extent of global warming argue that short-term temperature data are an inadequate means of predicting long-term trends and point out that the scientific community remains divided on whether significant warming will occur and what impact will it have if it does.
我选的D，不知道为何要选E，E前面是一般将来时，后面是将来完成时，前后不一致啊。是根据时态来判断的，还是有其他的区别，排除了D的？请老师解惑，谢谢！

The findings of the study mentioned in the highlighted text, if valid for rain-forest regions in general,  suggest that which of the following is an obstacle most likely to be faced by those wishing to promote rain-forest preservation by implementing the proposal mentioned in the highlighted text?
听了以前的录音，但是不理解： 第一句只说了要保护rain forest 就要推广新技术，这些会带来什么结果，没说推广的方法呀？by reducing demand for new cropland讲的是新技术的结果而不是方法，而且D 选项中Ready availability of uncultivated land并没有在第一句中体现。 看第一句之后，读选项之后发现无法选，选项提到的第一句内容都可以当作相同点去掉，剩下的是影响实施因素不同。而且题目问的是他们在实施过程中会遇到什么障碍，真正影响实施过程的是a recent study 后面的很长一段内容，讲了教育、土地的有无、kinship的影响，这三个中只有土地的有无影响人们是否接受新技术，其他两个都是讲接受了哪个新技术，就暗示了他们已经接受了新技术，根据这个就可以选D。 但是这样看很花时间，如果要看那么长的内容，考试中要怎么办？

For most people, the left half of the brain controls linguistic capabilities, but some people have their language centers in the right half.  When a language center of the brain is damaged, for example by a stroke, linguistic capabilities are impaired in some way.  Therefore, people who have suffered a serious stroke on the left side of the brain without suffering any such impairment must have their language centers in the right half.
 
Which of the following is an assumption on which the reasoning in the argument above depends?
B和C范围出去了，可以排除。其中B（people who have not suffered any damage ）和C（any other cause of damage to language centers ）不是原文范围，留下A D E.比不出来。 For most people, the left half of the brain controls linguistic capabilities, but some people have their language centers in the right half. When a language center of the brain is damaged, for example by a stroke, linguistic capabilities are impaired in some way. Therefore, people who have suffered a serious stroke on the left side of the brain without suffering any such impairment must have their language centers in the right half. Which of the following is an assumption on which the reasoning in the argument above depends? No part of a person's brain that is damaged by a stroke ever recovers. Impairment of linguistic capabilities does not occur in people who have not suffered any damage to any language center of the brain. Strokes tend to impair linguistic capabilities more severely than does any other cause of damage to language centers in the brain. If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages at least one of them. It is impossible to determine which side of the brain contains a person's language centers if the person has not suffered damage to either side of the brain.
