The higher the level of certain vitamins and minerals in the bloodstream,
the better a person's lung function, as measured by the amount of air the person can expel in one second.
The lung function of smokers is significantly worse, on average, than that of nonsmokers.
Clearly, therefore, one way for smokers to improve their lung function is for them to increase their intake of foods that are rich in these helpful vitamins and minerals.

Which of the following is an assumption on which this argument depends?

(B) The lung function of smokers whose diets are rich in those vitamins and minerals is generally better than that of nonsmokers with comparable diets.
(E) Smoking does not introduce into the body chemicals that prevent the helpful vitamins and minerals from entering the bloodstream.

选E吧~~

本道题强调的是维他命和矿物质的对吸烟者作用~~

B选项将吸烟者与不吸烟者进行对比~无关选项

E项排出了一个使结论不成立的前提~~就是说如果吸烟者吸烟时体内产生一种化学物质，它阻碍维他命与矿物质发挥其作用

不好意思 b我看错了我理解成了摄入维他命和矿物质的吸烟者的肺功能要比不摄入的吸烟者的肺功能要好

为什么C不对？
C。People whose diets are deficient in those vitamins and minerals do not typically have other health problems in addition to diminished lung function.
C取非，除了饭里少维他命还有其他的病引起肝问题。不也削弱原文吗

C选项也是无关选项~~

还是那句话，本道题强调的是维他命和矿物质的对吸烟者作用~~C选项中扯到了其他的话题上去了~~有没有其他病引起肝问题并不影响维他命和矿物质的作用啊~~

不选C

咋会选到C去的，，，C的无关词实在太多了。
lz、、、、

c超级无关嘛。
题目是 1.血液里的V和M。 2。食物里的V和M。

那就有个缺口了，，，应该是食物和血液上的关系。

桥梁型的虽然我也错了，选到A了。应该是E才对。

我选了A ，为什么A 不对，如果说前提：吸烟的人比不吸烟的人少摄取有维他命的饮食，所以吸烟的人更应该多摄取这样的饮食。这么想有什么不对呢？

同问为何A不对，取非的话是吸烟的人和不吸烟的人吃的东西里含v和m量一样，不是削弱原文了么

作者: YEWCHOW 时间: 2011-10-16 20:44

(D) Stopping smoking will not typically improve lung function more than any diet changes can.
D为什么不对啊？好像没人选D ，但是我将D取非，不就是停止吸烟比改善饮食习惯更能改善肺功能。
排除了削弱原文的一种情况：给出它因-停止吸烟可以更好地改善肺功能
