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.
 
The argument above requires which of following assumptions?

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.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the 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.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

While they remove carbon dioxide from the air, conserve soil and water, and house thousands of species, forests also supply potentially valuable pharmaceuticals, and, as sources of building material and firewood, that provide employment for millions worldwide.
我听了前面的讲解还是不太明白D为什么不对？老师的解释是用并列来理解，可是我刚开始做这道题的时候，看到E选项的as.....不知道它修饰的是谁。而且D也可以说是并列啊，是pharmaceuticals和sources并列不行吗?而且后面跟for表目的也合情合理的啊。

At present the Hollywood Restaurant has only standard-height tables. However, many customers come to watch the celebrities who frequent the Hollywood, and they would prefer tall tables with stools because such seating would afford a better view of the celebrities. Moreover, diners seated on stools typically do not stay as long as diners seated at standard-height tables. Therefore, if the Hollywood replaced some of its seating with high tables and stools, its profits would increase.
The argument is vulnerable to criticism on the grounds that it gives reason to believe that it is likely that

Sales of telephones have increased dramatically over the last year. In order to take advantage of this increase, Mammoth Industries plans to expand production of its own model of telephone, while continuing its already very extensive advertising of this product.
 
Which of the following, if true, provides most support for the view that Mammoth Industries cannot increase its sales of telephones by adopting the plan outlined above?
留下了C、E。C感觉会影响销量。E说的是去年销量下降，感觉和原文相反，原文说的是去年销量上升。而且即便去年销量下降，也不能说明今年销量会上升或者下降。 还有课上解释E的时候说原文中的电话销量是整体市场的销量，一开始我理解成了是M公司的销量，所以想问一下如果是M公司的销量，会具体指出sales of M吗？如果没有指出，就默认是整个市场的？在其他提及到类似的销量、利润之类的题目里也是这样的吗？ 感觉大多数措施目的题原文讨论的都是未来，也就是计划实施之后，所以选项中出现了其他时间一般都不对，但这道题是例外，想知道怎么理解呢？还是措施目的题不能根据时间范围来判断呢？

By 1999, astronomers had discovered 17 nearby stars that are orbited by planets about the size of Jupiter.
这题在A和B里面纠结，A我个人理解是天文学家发现了17颗星星-被和Jupiter一样尺寸的planets环绕着的。B的意思是天文学家发现了17颗（被planets环绕着的）的星星和Jupiter尺寸一样大。不是很能理解B的错误原因。当时觉得句意，就是B的意思比A的好。。。那个them就是指代stars。谢谢。

The state religion of ancient China, which came into existence at least as far back as the Han Dynasty (206 B.C. to A.D. 220) and perhaps as early as the Western Zhou Dynasty (1050 B.C. to 771 B.C.), allowed only emperors performing the ritual worship of heaven, perceiving them as special links between the earthly and celestial realms.
我想请问一下Tina老师，这个题目一开始看到的时候主要关注了only emperors 和ritual worship 的位置差异，可是我看不出来有什么差异，请问这里是同意改写还是有语意的差别。在放弃了这个考点以后又看到了perceive,发现有主动也有被动，觉得perceive 这个动作可以由perceive 发出，于是又无从下手了。请问这个perceive 这里又有什么差别呢？因为这个题这两个差异我都没有看出来请问还有什么考点可以入手吗？请老师指教一下。谢谢老师

A ruined structure found at Aqaba, Jordan, was probably a church, as indicated in its eastward orientation and by its overall plan, as well as artifacts, such as glass oil-lamp fragments, found at the site.
这题我想问两个问题，一个是D选项的as indicates这里的indicates单复数错误，但是我不是很能看出来。能不能麻烦老师帮忙解释一下D的句子结构，是倒装么？以及为什么indicates错误了。还有一个问题就是，这题，是这个发现了的结构可能是个教堂这事情被xxxx indicate还是 教堂 被 xxxx所indicate了啊？我感觉这两个都挺相似的。谢谢老师。
