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.

Dressed as a man and using the name Robert Shurtleff, Deborah Sampson, the first woman to draw a soldier's pension, joined the Continental Army in 1782 at the age of 22, was injured three times, and was discharged in 1783 because she had become too ill to serve.
我的思路： 看到未划线的JOIN，判断是谓语动词，然后直接排除AB 然后C的DISCHARED前后不一致，应该加WAS,排除 在DE中选了D 但为何答案是A啊？

A Harvard anthropologist has proposed that using fire to cook
food could be dated back to almost two million years and that
it could explain hominid features like having a large brain and
small teeth.
这道题通过比较，语义强调的是使用火这个行为可以追溯到什么时候，而非火本身，因此把DE排除 比较ABC的时候发现A中有一个it，不如BC那么明确，就留下BC BC差距主要在，the use of fire to cook和cooking with fire，date back有没有to，以及could explain和explaining 但是这三处区别我都比不出来，就选了个C

Absolute, or perfect, pitch—the ability to identify the pitch of an isolated musical note—is rare in the general population, but relatively common among trained musicians.  A survey of fifteen-year-old music students showed that absolute pitch was more common among those who had been studying music since a very early age than among those who started studying a few years later.  Thus very early musical training aids in the development of absolute pitch.

Many residents of Calovia are committed to using products containing recycled materials.  Soon these consumers will get help in identifying such products from a book being published by the Calovian government.  The book offers a comprehensive listing, by product type and brand, of goods sold in Calovia that contain recycled material.  Therefore, publication of the book will almost certainly increase the use of products containing recycled materials in Calovia.

Paleontologist: About 2.8 million years ago, many species that lived near the ocean floor suffered substantial population declines.  These declines coincided with the onset of an ice age.  The notion that cold killed those bottom-dwelling creatures outright is misguided, however; temperatures near the ocean floor would have changed very little.  Nevertheless, the cold probably did cause the population declines, though indirectly.  Many bottom-dwellers depended for food on plankton, small organisms that lived close to the surface and sank to the bottom when they died.  Most probably, the plankton suffered a severe population decline as a result of sharply lower temperatures at the surface, depriving many bottom-dwellers of food.
In the paleontologist's reasoning, the two portions in boldface play which of the following roles?

In the major cities of industrialized countries at the end of the nineteenth century, important public places such as theaters, restaurants, shops, and banks had installed electric lighting, but electricity was in less than one percent of homes, where lighting was still provided mainly by candles or gas.
1.看到问题后的第一反应是去找BUT前后的对应关系，前面的主语是pubic places,立即反应后面也应该是地点而不应该是electricity 2.五个选项看了一眼只有E符合 3.把E读了一遍没有发现致命错误，就直接选上了 听老师上次所讲内容A中的 .....homes，where...临近，对应比E更好，但是在临场状态下注意力第一步一定是放在but前后的，逼出优劣以后因为是紧迫会导致轻视其它区别，请问老师是否有解决的方法，去改变第一反应下的做题思路 谢谢老师！

In the sixteenth century, the push for greater precision in measuring time was not, like more recently, motivated by complicated philosophical questions about the nature of matter and the universe, but the practical matters of navigation:  sailors simply needed more highly accurate timepieces in order to compute their longitude from the positions of the stars.
C：like they were more recently E：as has been the case more recently 除了觉得C恶心，从单复数（前面用的是was）可以判断吗？否则我会觉得E中has been的发起者需要人琢磨，请老师解惑，谢谢。

In laboratory rats, a low dose of aspirin usually suffices to block production of thromboxane, which is a substance that promotes blood clotting, but not seriously interfering with the production of prostacyclin, which prevents clotting.
1.句意：在实验的rats中，小量a足够去阻止产生t,（t是）一种促进凝血的物质，但是（小量的a）不会阻止产生pr,（pr)防止结块 2.看到句子里有个but，根据并列，AB是interfering,扔；E是interference，扔 3.留下CD比较，发现区别在于D中有个which is, 又看到划线外面有个which prevents..所以就选了D 但是答案选C，于是检查之前的步骤 发现自己的第三步有错误，应该先根据CD的句意的区别，发现CD都是一个意思，这个时候用简洁的优先性，判断出D中的which is 啰嗦，所以选择C 听之前的讲解，老师说interfere和promotes对应，但我之前想的是interefere和suffice对应，到底谁和谁并列呀？
