19,Orthodox medicine is ineffective at both ends of the spectrum of ailments. At the more trivial end, orthodox medicine is largely ineffective in treating aches, pains and allergies, and, at the other extreme, it has yet to produce a cure for serious, life-threatening diseases such as advanced cancer and lupus. People turn to alternative medicine when orthodox medicine fails to help them and when it produces side effects that are unacceptable to them. One of the reasons alternative medicines is free of such side effects is that it does not have any effects at all.

19. The charge made above against alternative medicine is most seriously weakened if it is true that

(A) predictions based on orthodox medicine have sometimes failed, as when a patient has recovered despite the judgment of doctors that an illness is fatal

(B) alternative medicine relies on concepts of the body and of the nature of healing that differ from those on which orthodox medicine is based

(C) alternative medicine provides hope to those for whom orthodox medicine offers no cure

(D) a patient's belief in the medical treatment the patient is receiving can release the body's own chemical painkillers, diminish allergic reactions, and promote healing

(E) many treatments used for a time by orthodox medicine have later been found to be totally ineffective

答案

, 我在C/D中选择,选C.
我觉得C比D更好,结论:alternative medicine 无效,才没有副作用.C直接说alternative medicine 有效,可能能治正规药不能治的病.D提出了他因,不如C直接.

Oscar: Emerging information technologies will soon make speed of information processing the single most important factor in the creation of individual, corporate, and national wealth. Consequently, the division of the world into northern countries ?in general rich ?and southern countries ?in general poor ?will soon be obsolete. Instead, there simply will be fast countries and slow countries, and thus a country's economic well-being will not be a function of its geographical position but just a matter of its relative success in incorporating those new technologies

Sylvia: But the poor countries of the south lack the economic resources to acquire those technologies and will therefore remain poor. The technologies will thus only widen the existing economic gap between north and south.
8. Sylvia's reasoning depends on the assumption that

(A) the prosperity of the rich countries of the north depends, at least in part,, on the natural resources of the poor countries of the south

(B) the emergence of new information technologies will not result in a significant net increase in the total amount of global wealth

(C) there are technologies other than information technologies whose development could help narrow the existing economic gap between north and south

(D) at least some of the rich countries of the north will be effective in incorporating new information technologies into their economies

(E) the speed at which information processing take place will continue to increase indefinitely

答案

,我在B/D中选取择,选了B
南方穷国没有经济资源,获得科技,结果更穷了.=>科技加大南北经济差距.
D,bridge这个结论,B好象也好,not + 否定?

谢谢!
