CR
碰到兩題GWD的題目,不過只想起來一題, 我會努力再想想的
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.

另有一題, 是說太陽能的, 說太陽能發電雖然環保且單位電費便宜,但要裝設線路卻很貴,甚至不能回收, 然後說仍有部份人裝設太陽能發電設備, 問assumption這些人不是因為經濟因素裝設
Ans: 我選C, 裝了太陽能設備的房子 賣的時後價錢沒有比沒裝太陽能設備的房子貴
(注意 題目有問經濟因素, 其他選項都沒提到錢)

遇到本月JJ第二篇有關RNA
補充一下 : 文章共兩段(長),考了4題, 有三題都在第一段, 其中一題是出在第一段最後一句 (舉了一些動物說明第三類，RNA的發現與已有zoologist的觀點截然想法), 問in order to

遇到本月JJ第八篇有關廣告 version 3
補充一下 : 文章共兩段(短),考了3題, 文章架構一開始說competitive比較有說服力, 接著轉折說有一些研究推翻了, 但到了第二段作者指出後者研究上的缺點, 所以作者還是支持原來competitive較好,請注意作者的態度, 會考.

遇到本月JJ第十一篇有關美國科學界女性被歧視的問題
補充一下 : 文章短,考了3題, 原來JJ version 1 寫的很清楚, 連考點都一樣

Math
遇到很多JJ, 整理如下

16. 一個正六邊型(六邊形hexagon)ABCDEF（A為左上定點，然後各點按逆時針順序標，上下兩邊水準），中間還有連接BE的一條直線，問六邊形面積。
1):六邊形邊長為xxx，具體數字忘了。
2)BE長xxx
Ans : D
17.DS:已知r,s是正數，r+s=1,問r<s?
1) r>0
2) s>0.5r^2
Ans : E
27. 20/(2^m)=1/(2^m)+1/(2^n) m，n是整數，求mn=?
Ans : 3
29. 6個人同時參加2個，分組別占A組和B組的20%和25%，問只參加一個組的有多少人。
Ans : 42
補充一下 : 我碰到的數字有換
43. 2-height那題, 不過題目應為下
補充一下 :
X is a positive integer. 2-height of X is defined as the greatest non-negative integer n where 2^n is a factor of X. K and M are two positive integers. Whether 2-height of K is greater than 2-height of M?
a. K is greater than M
b. K is even times of M
Ans : B
53. x^2>y^2, 問x>y? DS題, [x]>y, [y]<x
Ans: B
63. A certain dealership sells three types of automobiles, cars, trucks, and vans. the ratio is 4:5:7. How may cars have the dealership sold?
1, the number of van sold is between 10 and 20,
2, the number of cars sold is less than 10.
Ans : A
69. 一個公司35個人, 分別都幹了不同時間的活.. 列了一個表, 表裏說明有多少人幹了多少活, 問Median 只是要小心點, 縱軸表示人數, 橫軸表示小時數, 別看花了.
補充一下 : 最後一種共有10人, 倒數第二種共有8人, 所以答案選倒數第二種
88. 一個大長方形被數條橫線平分為未知個小長方形, 給了大長方形的周長和每個小長方形的周長(具體數字不記得了), 問小長方形的寬是多少. (有圖形, 小長方形的長=大長方形的長, 最後我是用代入法的, 算出關係後把每個選項逐個代入, 答案我選的"7")
128. 已知P(N,r)= N!/(N-r)! ，問r最小是幾能滿足p(10,r)>1000？
Ans : 4
149. 一個東西以高於其成本價格的50％銷售，問該產品的利潤率是多少？
補充一下 : 我碰到的是說 現在要降價, 降到成本價出售, 降價百分比是多少
Ans : 33.33%
160. 說生產兩種東西P,Q. 上一個月P的產量占總共的10%,第二個月P產量增長而Q不變,於是兩個月裏P的總產量占所有PQ產量的20%,問第二個月P多生產了多少.哦,對,兩個月總產量是9000好象.
補充一下 : 我碰到的是兩個月的P差了多少
Ans: 1000
189. DS：一個四邊形分為3個三角形，問中間的三角形面積等於其他兩三角形面積和嗎？
a.這個四邊形長等於寬的2倍
b．這個四邊形是平行四邊形
補充一下: 這題有給圖,貌似平行四邊型, 但題目只有說是四邊型 ; 條件a只給其中一邊長是另一邊寬的兩倍 (並不是兩個長都是兩個寬的兩倍), 所以我覺得a不能選, 大家再自己判斷一下

補充一題新的 : 議會中有25個立法人, 其中有n個人要提案, 這n個人(each)要將他們的提案給剩下非提案的人看(each), 且非提案的人(each)都要回一封letter給每個提案的人, 問提案+letter = ?
(題目有點繞, 注意 each)
Ans : n(25-n) + (25-n)n = 2n(25-n)

給大家一點信心

我去年 10月 11月 都考過
今年1月是第三戰了
math 這個月真的比較簡單 jj以外的題目也都不難
甚至有幾題都是簡單的運算 (指數運算 分數運算...)
看到時不要太害怕 以為考壞了 真的就是這麼簡單
不過要小心運算 注意配速
(我就是前面衝太快 抬頭看時間時 還有30分時 只剩8題)
比較簡單時 可能意味錯題不能太多 不然很容易被扣分
所以 大家要有信心 好好把握這個月

加油...
