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

第一题在A和E之间纠结……但是A忽略了smoking等等的因素 所以应该选E？
第二题E？感觉其他都不对。。。

E;C

觉得第一题选E。从意思上读下来最顺。如果选A的话都不需要后半段介绍什么吸烟锻炼这些生活习惯了，似乎完全miss掉后面的内容不太合理。

第二题选A吧。两种病的处理方法不同，如果Cerebral edema当普通病来处理，就会很危险。E有点模糊，似乎也讲得通，但是没有A提到两者对比来得好。

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

第二题 答案是A

liy123456

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。

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,
