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.

D

Museums that house Renaissance oil paintings typically store them in envbironments that are carefully kept within narrow margins of temperature and humidity to inhibit any deterioration. Laboratory tests have shown that the kind of oil paint used in these paintings actually adjusts to climatic changes quite well. If, as some museum directors believe,paint is the most sensitive substance in these works, then by relaxing the standards for temperature and humidity control, museums can reduce energy costs without risking damage to these paintings. Museums would be rash to relax those standards, however, since results of preliminary tests indicate that gesso, a compound routinely used by Renaissance artists to help paint adhere to the canvas, is unable to withstand significant variations in humidity.
 
In the argument above, the two portions in boldface play which of the following roles?
我选了c。黑体说的更像事实，读了选项没有EVIDENCE, FACT字眼无法排除任何选项；然后通读了文章，发现这是一个判断究竟是paint是最敏感物质还是gesso,所以觉得可能judgement更好，objection/position/claim是表达观点；直接排除ABE；做题时脑中一闪而过的想法-把他清晰呈现就是C中我们可以节约成本在不损坏油画的前提下，这个是基于我们知道如何不损坏油画，而知道颜料是最敏感的物质应该也算我们知道如何避免损坏油画的一个思路…有那么一点base/基于的味道，我看了D是答案，我觉得可能是观点；可是如果说真正的观点，结合However，应该是museums would be rash to relax those standards；我感觉是我没有理解这段话。非常混乱的感觉。想了想老师说的阅读方法－however后面一般是作者的观点；但也有hypothesize, argue, believe,这种词语后面可能是作者观点；纠错过程觉得越来越混乱….

Although improved efficiency in converting harvested trees into wood products
may reduce harvest rates, it will stimulate demand by increasing supply and
lowering prices, thereby boosting consumption.
when 没有in,of好，排除E；D中的Being多余；converted直接被动语态可以修饰trees；boost应该修饰prices单复数排除C；但如果修饰demand则为单数排除B；但如果increasing, lowering, boosting均平行；则排除BC；选A；语义我不知道是否需要3个平行。我不太清楚如果这种情况下 感觉语义都可以 应该怎么处理。 (之前我也问了金老师类似语义区分。我认为runners of horses可以/老师说没有human runners of horses 这种表达。大概也是我语义不明。我觉得无所谓都可以因为语义是清楚的 可能表达不准确。有没有什么文章/方法能提高?

To map Earth’s interior, geologists use a network of seismometers to chart seismic waves that originate in the earth’s crust and ricochet around its interior, most rapidly traveling through cold, dense regions and slower through hotter rocks.
想请教Tina老师，Tina老师在课上讲v.-ing形式的动作发出者是主句的主语或整个句子，但在这个题目中，traveling的动作发出者应该是waves，是不是因为它伴随的是修饰waves的宾语从句，在这种情况下对应的发出者就是宾语从句的修饰对象，而不用追溯到主句的主语呢？谢谢老师

因为have done的句意先后问题；所以划线部分就用一般现在时最好，排除ABDE；尽管C的后面平行结构太差了并且用的是一般过去时；A的平行结构最好，但是我感觉句子中不能同时出现俩个完成时态，因为无法有先后；我目前知识概念中1）had done先于一般过去时，have done先于一般现在时；have done与一般过去时的先后无法判断（这道题就是）；2)且有have done这些的不能用with这种表示伴随状态的介词引导-因为有先后问题而非并列；had done先于have done；3）一般有一个have done，为了表示一个先后完整度，句子的另一个部分应该要补出另一个对应时态的动词或者补出对应的时间标志词（这道题俩个时间标志都有）；回归原文，俩句话（but连接）都有时间标志词，所以可以用完成时？根据句意这俩个认知都是持续到了现在，用现在完成时都是可以的；老师能否再补充或拓展一下（关于时态的问题，我一般做题时看到一个句子中同时出现have done我就直接排除了，因为句意一般有先后顺序的问题）？如果从语义出发（保留所有的完成时态），并且强调动词与主语的关系，可以排除DE（无法体现emerge这个动作）；根据平行结构，排除BC；

金栩竹老师经常强调完成时的在句意表达的先后,我也觉得很好用。这题判断方法 因为have done的句意先后问题；所以不能用完成时，排除ABDE；尽管C的后面平行结构太差了；A的平行结构最好，但是完成时语态；老师说了had done最先发生，have done后发生，一般现在时最后发生；这里语义重心在后半句，前半句用了have known，则代表了先发生，后半句最好不要用语态，一般现在时最好；这里面老师可否再多说一点时态问题。
