陈向东 假设
37、editorial:
critics of nuclear power complain about the allegedly serious harm that might result from continued operation of existing nuclear power plants. but such concerns do not justify closing these plants; after all. their operation has caused no more harm than that caused by pollution generated by coal-and oil-burning power plants, the most immportant other sources of energy.
which of the following is an assumption on which the argument depends?
b. closing existing nuclear power plants would require greatly increased reliance on coal-and oil-burning power plants.
d. the harm that a nuclear power plant is likely to cause as it continues to operate can be reliably predicted from the past history of nuclear power plants.
答案是：D
D明白！为什么书上说B去掉greatly 就是假设呢？？怎么可能？？
50 within 20 years it will probably be possible to identify the genetic susceptibility an individual may have toward any particular disease. eventually, effective strategies will be discovered to counteract each such susceptibility. once these effective strategies are found, therefore, the people who follow them will never get sick.
the argument above is based on which of the following assumptions?
c. all human sicknesses are in part the result of individual's genetic susceptibilities.
d. all humans are genetically susceptible to some diseases.
答案是：C
可是C中有in part啊！！那还有不是因为genetic susceptibilities导致的sicknesses啊！怎么能说will never get sick呢！
d为什么不对呢？
还有书上说在假设选项中出现only,solely,in part, partly可以忽略，在取非判定时尤其如此。但在段落中出现这四个词要格外关注！果真是这样吗？？

37. 我认为Ｂ是无关选项．但是有一点要注意，在assumption的题型中，如果选项中有表示程度和范围的词，如most, definitely, probably, greatly, all等，要格外注意，此选项很可能错，要仔细分析原文是不是能推导出这个程度和范围．

50. C说明ＧＳ是所有病的一个必要条件．所以conteract GS可以防止得病．Ｄ意思不对，取非后：不是所有的人都genetically susceptible to some diseases, 对原文结论无影响．

对only, solely等词汇的总结我认为没有必要细化到在原文中还是在选项中，既然出现了，总是有用．这道题中in part就说明ＧＳ是一个必要条件．

请对此有心得的朋友补充．

我理解50中的IN PART指的是ALL human sicknesses都部分地同。。。有关，所以这是一个必要条件，如果取非，则是不是所有的病都同。。。有关，是NOT WEAKEN。另外，我觉得绝对词汇排除的条件是在文章中的结论不是绝对词汇的结论，是推导过程的严谨性，如果文章结论有了绝对词汇，当然其成立的必要条件有绝对词汇并不一定错。个人观点。
