碰到两题GWD的题目,不过只想起来一题, 我会努力再想想的

GWD31套-第17套-Q9: (Ans: B)

Press Secretary:  Our critics claim that the President’s recent highway project cancellations demonstrate a vindictive desire to punish legislative districts controlled by opposition parties.  They offer as evidence the fact that 90 percent of the projects canceled were in such districts.  But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors.  So the President’s choice was clearly motivated by sound budgetary policy, not partisan politics.

Which of the following is an assumption on which the press secretary’s argument depends?

A.      Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.

B.       The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party.

C.       The number of projects canceled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future.

D.      The highway projects canceled in districts controlled by the President’s party were not generally more expensive than the projects canceled in districts controlled by opposition parties.

E.       Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.

 

另有一题, 是说太阳能的, 说太阳能发电虽然环保且单位电费便宜,但要装设线路却很贵,甚至不能回收, 然后说仍有部份人装设太阳能发电设备,  问assumption这些人不是因为经济因素装设

Ans: 我选C, 装了太阳能设备的房子
                            卖的时后价钱没有比没装太阳能设备的房子贵

        (注意
                            题目有问经济因素, 其它选项都没提到钱)

遇到本月JJ第二篇有关RNA

补充一下 : 文章共两段(长),考了4题, 有三题都在第一段, 其中一题是出在第一段最后一句 (举了一些动物说明第三类，RNA的发现与已有zoologist的观点截然想法), 问in order to

 

遇到本月JJ第八篇有关广告 version 3

补充一下 : 文章共两段(短),考了3题, 文章架构一开始说competitive比较有说服力, 接着转折说有一些研究推翻了,  但到了第二段作者指出后者研究上的缺点, 所以作者还是支持原来competitive较好,请注意作者的态度, 会考. 

 

遇到本月JJ第十一篇有关美国科学界女性被歧视的问题

补充一下 : 文章短,考了3题, 原来JJ version 1 写的很清楚, 连考点都一样

补充一下
                            : 最后一种共有10人, 倒数第二种共有8人, 所以答案选倒数第二种

88. 一个大长方形被数条横线平分为未知个小长方形, 给了大长方形的周长和每个小长方形的周长(具体数字不记得了), 问小长方形的宽是多少. (有图形, 小长方形的长=大长方形的长, 最后我是用代入法的, 算出关系后把每个选项逐个代入, 答案我选的"7")

                            DS：一个四边形分为3个三角形，问中间的三角形面积等于其它两三角形面积和吗？

b．这个四边形是平行四边形

补充一下: 这题有给图,貌似平行四边型, 但题目只有说是四边型
                            ; 条件a只给其中一边长是另一边宽的两倍 (并不是两个长都是两个宽的两倍), 所以我觉得a不能选, 大家再自己判断一下

 

补充一题新的
                            : 议会中有25个立法人, 其中有n个人要提案, 这n个人(each)要将他们的提案给剩下非提案的人看(each), 且非提案的人(each)都要回一封letter给每个提案的人, 问提案+letter = ?

                            each)

Ans : n(25-n) + (25-n)n = 2n(25-n)
