ds：what is the value of|x| ?
(1) x=-|x|
(2) x^2 = 4
逻辑
three large companies and seven small companies currently manufacture a product with potential military applications. if the government regulates the industry, it will institute a single set of manufacturing specifications to which all ten companies will have to adhere. in this case, therefore, since none of the seven small companies can afford to convert their production lines to a new set of manufacturing specifications, only the three large companies will be able to remain in business.
which of the following is an assumption on which the author's argument relies?
a none of the three large companies will go out of business if the government does not regulate the manufacture of the product.
b it would cost more to convert the production lines of the small companies to a new set of manufacturing specifications than it would to convert the production lines of the large companies.
c industry lobbyists will be unable to dissuade the government from regulating the industry.
d assembly of the product produced according to government manufacturing specifications would be more complex than current assembly procedures.
e none of the seven small companies currently manufactures the product to a set of specifications that would match those the government would institute if the industry were to be regulated.
数学
答案：b
逻辑
答案：e
三小七大公司生产军品，现在政府开始规范这个行业，所以出台了生产制造标准。
因为小公司都没钱把自己的生产线弄成符合标准的，所以结论是只有大公司可以存在。
反驳：小公司没钱标准化生产不代表他们的`产品不符合规定!
a, 说的是如果政府不出台法规所产生什么结果，范围不对，杀;
b，说转换生产线小公司比大公司花钱多，无此比较，杀;
c，说游说者不能说服政府不要管这个行业，无关，杀;
d，新规定上产品的装配会更复杂，没说过，杀;
e，如果政府出台法规，七所小公司现在生产的产品不能够满足政府要求，
---文章中反复谈的就是能否满足要求的问题，靠谱，留着。
逻辑链: no match---->must convert--->can't afford--->out of the business
使得前提变唯一则文中的前提必然推得结论
假设题中，绝大部分的考题都是选项中含有否定词的为正确选项，取非后能驳斥原文的为对。

the number ofstamps that kaye and alberto had were in the ratio 5 : 3, respectively. after kaye gave alberto 10 of her stamps, theratio of the number kaye had to the number alberto had was 7 :5. as a result of this gift,kaye had how many more stamps than alberto?
(a) 20
(b) 30
(c) 40
(d) 60
(e) 90
【逻辑】
amphibian populations are declining innumbers worldwide. not coincidentally, the earth’s ozone layer has beencontinuously depleted throughout the last 50 years. atmospheric ozone blocksuv-b, a type of ultraviolet radiation that is continuously produced by the sun,and which can damage genes. because amphibians lack hair, hide, or feathers toshield them, they are particularly vulnerable to uv-b radiation. in addition,their gelatinous eggs lack the protection of leathery or hard shells. thus, theprimary cause of the declining amphibian population is the depletion of theozone layer.
each of the following, if true, wouldstrengthen the argument except:
a. ofthe various types of radiation blocked by atmospheric ozone, uv-b is the onlytype that can damage genes.
b. amphibianpopulations are declining far more rapidly than are the populations ofnon-amphibian species whose tissues and eggs have more natural protection fromuv-b.
c. atmosphericozone has been significantly depleted above all the areas of the world in whichamphibian populations are declining.
d. thenatural habitat of amphibians has not become smaller over the past century.
e. amphibianpopulations have declined continuously for the last 50 years.

题目翻译：kaye 和 alberto 的邮票数之比为 5比 3，当 kaye 给 alberto10 张邮票，邮票数之比为 7比 5 ，kaye 比 alberto 多几张邮票?
思路点拨：列二元一次方程，分别设 kaye 和 alberto 的邮票数为 x 和 y。 x/y=5/3, (x-10)/(y+10)=7/5,解方程即可。
caution!：记得求出 x 和 y 之后要相减
【逻辑】
答案：d
思路：原文论述臭氧层的破坏造成uv-b辐射过量是导致两栖动物数量减少的主要原因。
a：支持说明为什么是uv-b而不是其他原因。
b：支持说明为什么uv-b会降低两栖动物的数量。
c：提供空间论据说明臭氧层受损和两栖动物数量减少的相关性。
d：中性评价。不weaken也不strengthen.
e：提供时间论据说明臭氧层受损和两栖动物数量减少的相关性。
技巧：做except题如果答案中出现原文没有的专有名词(地名和人名等)一般就选它。
