再来两道逻辑,求解!

27. These days, drug companies and health professionals alike are focusing their attention on cholesterol in the blood. The more cholesterol we have in our blood, the higher the risk that we shall die of a heart attack. The issue is pertinent since heart disease kills more North Americans every year than any other single cause. At least three factors---smoking, drinking, and exercise—can each influence levels of the cholesterol in the blood.
Which one of the following can be properly concluded from the passage?
(A) If a person has low blood cholesterol, then that person’s risk of fatal heart disease is low.
(B) Smoking in moderation can entail as great a risk of fatal heart disease as does heavy smoking.
(C) A high-cholesterol diet is the principal cause of death in North America.
(D) The only way that smoking increases one’s risk of fatal heart disease is by influencing the levels of cholesterol in the blood.
(E) The risk of fatal heart disease can be altered by certain changes in lifestyle.

28. Ordinary mountain sickness, a common condition among mountain climbers, and one from which most people can recover, is caused by the characteristic shortage of oxygen in the atmosphere at high altitudes. Cerebral edema, a rarer disruption of blood circulation in the brain that quickly becomes life-threatening if not correctly treated from its onset, can also be caused by a shortage of oxygen. Since the symptoms of cerebral edema resemble those of ordinary mountain sickness, cerebral edema is especially dangerous at high altitudes.
Which one of the following is an assumption on which the argument depends?
(A) The treatment for ordinary mountain sickness differs from the treatment for cerebral edema.
(B) Cerebral edema can cause those who suffer from it to slip into a coma within a few hours.
(C) Unlike cerebral edema, ordinary mountain sickness involves no disruption of blood circulation in the brain.
(D) Shortage of oxygen at extremely high altitude is likely to affect thinking processes and cause errors of judgment.(E) Most people who suffer from ordinary mountain sickness recover without any special treatment

哈哈第一题E，第二题A。个人觉得第二题在讲因为两种情况的症状很相似所以很容易把cerebral edema当成mountain sickness延误了治疗，从而使人觉得cerebral edema更加危险。因此，假设应当是建立在治疗方法上的。

噢,懂了,A

我选的是E；A
我的思路：
第一题：文章的逻辑是smoking, drinking, and exercise→cholesterol→heart attack, 结论就是smoking, drinking, and exercise→heart attack, 也就是life style→heart attack，所以选E；
第二题：文章逻辑
high altitudes→shortage of oxygen→Ordinary mountain sickness
                       shortage of oxygen→cerebral edema                        →cerebral edema在high altitude特别危险
Ordinary mountain sickness和cerebral edema的symptoms一样
文章想建立cerebral edema和high attitude之间的联系，最直接的巩固方法就是建立Ordinary mountain sickness和cerebral edema之间的关系，因为Ordinary mountain sickness和high altitude有直接的逻辑关系。这样排除一下就只有A/C剩下。细看C，disruption of blood circulation属于病症细节，一不一样没有太大影响，而且从外化的病症无法判断。还下不了决心就回看A，说两个的处理方式是不一样的。结合文章给的两者病症相似，就能退出有面对cerebral edema使用了不对的应对Ordinary mountain sickness的方法，导致不能迅速治愈最终产生especially dangerous。比较一下，A给出的逻辑明显更加清晰。

对的

第二题A，注意“....that quickly becomes life-threatening if not correctly treated...."----第二种病不正确treat的话会变得很危险  就因为两者treatment不一样，但是symptoms是相似的，所以容易treat不正确，导致第二种病很危险~ 不知这样理解可否

sun_lizzy

原文已经明确指出两者的症状是相似的
Since the symptoms of cerebral edema resemble those of ordinary mountain sickness,

第2题选C
      C的句子意思其实是：“Cerebral edema”和“高原病”发作起来的症状是不一样的。
起到了前提作用。  
    想一想，要是这两种病的发病原理或者症状相似，那么逻辑选文的探讨将无任何意义。

第二题 答案是A

liy123456

E, c
第一题：很简单选出E。
     A中研究low blood cholesterol时候的情形，而逻辑原文只谈到high bolld的，杀了
     B中讨论中等强度的抽烟所产生的情形，更不想干，和逻辑原文，杀了
     C提到说blood cholesterol diet是北美主要致死原因，逻辑原文不涉及北美死亡原因，谁是主要谁是次要，这些方面的探讨，杀
     D唯一的方式是通过影响什么什么... 说的绝对而无任何依据，杀了。
     E说可以通过改变生活方式治愈疾病。和原文逻辑accidently呼应。（原文探讨：    1致病原因；2吸烟、饮食以及运动跟XX疾病的关系）


第2题选C
