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.

问： 王文静老师麻烦教一下这道题目，我选了b,排除了a,因为我觉得a里面不能用it,1990-2000的经济和农耕文化开始的1000年里面的经济不一样啊，it不是指 between 1990 and 2000 the global economy吗，我觉得要用that.就比如一道小汽车的题目(见下图):由于现代技术的发展，现在的小汽车要比以往任何时候的小汽车都省油。这个小汽车就是不同时代的比较啊。然后c我排除的原因是that which had been时态不对，d it has been这里面的it指的是前面的the growth of the global economy between 1990 and 2000, E名词和主谓比不对等。不知道这样看对吗?

Driving the steep road to the mountaintop Inca ruins of Machu Picchu is potentially dangerous and hiking there is difficult.  Now the Peruvian government is installing a cable car that will make access much easier, and hence result in a large increase in tourism.  However, since the presence of large numbers of tourists tends to accelerate the deterioration of a site, installation of the cable car is certain to result in harm to the ruins.
 
Which of the following, if true, most seriously calls into question the argument?
求问陆旭老师这题的C为什么不对呀？我选对了E，但是我在犹豫C，因为我觉得逻辑链是：因为用了cable car——导致游客增加——最终导致deterioration加剧。那C说游客本来就多，所以有没有这个car影响不大。我也知道逻辑链本身是不完整的，但是我觉得E也不完整，因为E里面只说了tour bus会造成significant damage，但并没有说这个damage到底是高于cable car还是低于cable car。这与C异曲同工啊，都没有明确的程度来区分cable car造成ruin的强弱。所以有些迷惑。。。。。

提问： 王文静老师，我想问个关于',＋doing'和and的问题，下面整理的问题，我都是在这个地方出现犹豫或者选错,真的是屡做屡错，字有点多，麻烦老师看下啦 Q849是一个句子＋doing的结构，letting引导的是一个对前面动作进行补充解释的动作，与前面的句子是有关系的，所以不能用and去连接，因为and连的是相互独立的没有关系的动作或者事情 Q851 gives mouth和displace grasses并列，造成的结果用rendering作为引导跟在后面，也算是补充解释 Q862也是句子＋,＋doing作为前面一整个句子的补充解释 但是问题来了，Q858 B选项，south are hunting crops and therefore raising这个为什么能对? and不是连接相互独立的两个部分吗，那therefore就是表示因果关系的啊，这不是矛盾了吗，还是这道题目主要的考点不在这里而在于平行，所以有瑕疵也是可以容忍的? Q 865虽然正确选项B可以通过其他考点排除，但是'overcompensating，growing'为啥不好呢，growing an extra one or two不能作overcompensating的补充解释吗，这里有必须选and不选doing,doing的理由吗？

The Acoma and Hopi are probably the two oldest surviving Pueblo communities, both dating back at least a thousand years.
请金老师回答。 之前您在语法基础课中讲过 each 、every、each of 后面V的单复数使用有3种情况：1） each/every 作主语，V用单数；2）each在主语后面作同位语，V 跟主语单复数一致；3）each of+复数名词作主语，V用单数。 我发现自己对这类句型，尤其是 each/ the one / the only one of +从句，我对从句中V的单复数判断不太好。 比如 例题 The Acoma and Hopi are probably the two oldest surviving Pueblo communities, each one of which date back ate least a thousand years. 中，date就不该用复数。 我在网上找到2个例句（如下），为什么第一个 从句中用are，第二个用is ？ 还是例句错了？希望您能再举些考试可能碰到的例句 He is one of the students who are never late. 他是学生中唯一从不迟到的学生 He is the only one of the students who is never late. 他是学生中唯一从不迟到的学生

After increasing steadily for centuries, the total annual catch of all wild fish peaked in 1989; since that time, the total catch for most species has declined or plateaued, prompting conservation efforts designed to help prevent population crashes and possible extinctions.
请金栩竹老师解答 金老师好，这题末尾未划线的地方有个疑问： 1）中间是省略了that？ 否则后面 prevent 谓语动词无法解释？ 2）designed to 表旨在、为了，过去分词表被动？ prompting conservation efforts （that）designed to help prevent population crashes and possible extinctions.
