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.

Plant scientists have used genetic engineering on seeds to produce crop plants that are highly resistant to insect damage.  Unfortunately, the seeds themselves are quite expensive, and the plants require more fertilizer and water to grow well than normal ones.  Thus, for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer.  However, since consumer demand for grains, fruits, and vegetables grown without the use of pesticides continues to rise, the use of genetically engineered seeds of this kind is likely to become widespread.

A study of children of divorced parents found that ten years after the parents’ divorce, children who had been under six years of age at the time of the settlement were not preoccupied, nor even very curious, about the reasons that led to their parents’ divorces.
这个题选了c，首先觉得neither nor是比较舒服的形式，开始看ce，e里面两个宾语是一致的感觉没必要用代词。 反思：首先搭配问题是不是可以先放过，not or和neither nor都可以。但这个curious about介词搭配算不算考点?感觉curious with也可以，另外bc比，c里面的that从句是做修饰语，不如b里面充当句子成分。 这个介词还有像not or这样的搭配，什么时候应该注意，什么时候应该放过……很晕 to Tina老师

Lacking information about energy use,people tend to overestimate the amount of energy used byequipment, such as lights, that are visible and must be turned on and off and underestimate thatused by unobtrusive equipment,such as water heaters.
这个题的e选项，因为前面存在the amount of energy ，可以指代，所以放过，并且形式正好和前面对应。看d里面的underestimate that后面的that是做代词吗?记得上课讲，that 和those可以直接补充出后面的修饰对象，但this不能单独出现，那these可不可以单独出现呢?D，E里面有犹豫。
