标题: 丁丁倒数 41# [打印本页] 作者: 玛莎丁丁 时间: 2012-8-28 22:33 标题: 丁丁倒数 41# 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.作者: 玛莎丁丁 时间: 2012-8-28 22:35
A is the answer. If I change the "most" in choice E to "all" , would it be correct answer as well?作者: lihaolan 时间: 2012-8-30 14:53
YES，if you change to all。it is just like the answer A，however,A maybe better for its containing two sick!作者: 小MMM 时间: 2023-4-20 21:50
高海拔低氧，造成爬山病，很普遍可以好。CE这个病可致死，也由缺氧造成。CE和爬山病的症状很像，所以CE在高海拔时尤其危险。找假设。
类比型。原文隐藏的是，爬山病在高海拔不危险。那我要说的其实是，二者不同，二者不类似。A很直接说二者differ。
A，取非，如果治疗CE和治疗爬山病的方法一样，那么在高海拔得了CE就直接用爬山病的方法治疗，就不会especially dangerous了。否定了结论。正确答案。
错选：觉得treatment是无关选项。
备注：什么叫especially dangerous？就是救不活，那么就应该自然而然想到选项会说治疗方法。
