GWD3-Q31:

Although most smoking-related illnesses are caused by inhaling the tar in tobacco smoke, it is addiction to nicotine that prevents most smokers from quitting.  In

an effort to decrease the incidence of smoking-related illnesses, lawmakers in Sandonia plan to reduce the average quantity of nicotine per cigarette by half over the next five years.  Unfortunately, smokers who are already addicted to nicotine tend to react to such reductions by smoking correspondingly more cigarettes.

 

The information above most strongly supports which of the following predictions about the effects of implementing the Sandonian government’s plan?

 

1. The average quantity of tar inhaled by Sandonian smokers who are currently addicted to nicotine will probably not decrease during the next five years.
2. Sandonian smokers who are not already addicted to nicotine will probably also begin to smoke more cigarettes during the next five years than they had previously.
3. The annual number of Sandonian smokers developing smoking-related illnesses will probably decrease during the next five years.
4. The proportion of Sandonians attempting to quit smoking who succeed in that attempt will probably decrease during the next five years.
5. The number of Sandonians who quit smoking during the next five years will probably exceed the number who quit during the last five years.

通过排除法，好像答案只能选A，可是仔细看了一下，觉得原文与提目有偷换概念的意思。原文中说减少的是nicotine, 而提干A中说的是tar没有减少。我原来选A，是根据原文说虽然每只香烟中nicotine的数量减少了一半，但是每个人吸的数量多了，所以应该是nicotine的数量没有减少，但A选项说的是tar的数量没有减少。我觉得应该翻倍才对。（通过查询nicotine和tar好像完全是不同的事物）。如果这样理解的话，是不是A选项也对呢？

极度迷惑中。。。。。。。。。。。。。。

1 吸入tar导致smoking相关的疾病

前提：
        2 Nicotine会阻止吸烟者戒烟

  Lawmakers为了减少smoking相关疾病，提出计划：建议减少烟里的nicotine含量，然而不幸的是，已经对nicotine上瘾的人会相应的增加吸的烟数目。

题目要求一个对这个计划的预测：

A 选项意思是针对“smokers who are currently addicted to nicotine”的，他们就像文中说的，不会因为nicotine 的减少和以前吸一样的烟的数量（结果也就是按lawmakers的意愿使smoking 的疾病减少），反而会增加烟数，那么对这群人而言，烟的数量增加了，所以即使nicotine 量下降，吸进去的tar 量也不一定下降。
B没办法预测，题目未提供不上瘾的人的信息。
C D E同理，无法判断。
纯属个人看法哈~~欢迎各位大牛提意见！

B:who are not already addicted 超出討論範圍
D:The proportion of Sandonians attempting to quit smoking超出討論範圍
E:The number of Sandonians who quit smoking超出討論範圍

C:weaken(政府目的:to decrease the incidence of smoking-related illnesses)

吸烟引发的疾病是由烟草中的tar导致的，沉迷nicotine会妨碍戒烟。
为了减少疾病，立法者计划未来5年，减少每支烟的nicotine含量。
但是！！沉迷nicotine的吸烟人会抽更多。

为了支持这个结果，A是引发吸烟相关疾病的tar不会减少，所以government的plan不会起到预期效果。
