几道5月的JJ请教一下各位： 13. 一社区有45户, 订报纸, 有 R, S, T 三种报,给出了三种报的订户人数分别是, S1=28, S2=17, S3=12,then, subscribe, both R&S, b1=9, both S&T b2=8, both R&T b3=7; Now 给出了一个重要条件, 订了三种的和什么都没有订的人,一样. 然后说, at least subscribe one kind of newspaper,29. 问: Subscribe only one kind Newspaper 的人数 X=? [讨论]：X=S1+S2+S3-2B1-2B2-2B3+3a, 其中a是三种报纸都订了的户数 a=45-29=16 题目数字有没有错，both S&T b2=8, both R&T b3=7有没有包含三种都订的？
39． 有一个屋子要进行某种加工。A公司头500平方尺收￥2， 以后每平方尺收￥2.7。 B公司每平方尺收￥2.4。问雇A公司是否比B公司合算？ 1. 屋子more than 1000平方尺 2. 屋子less than 1200平方尺 [确认]：C [思路]：设多出500的面积是x, 那么当A公司和B公司收费相等时：1000+2.7*x=2.4*(500+x), 解得：x=2000/3, 所以，当屋子面积大于1000，小于1200时，聘请A公司比较划算 我选E
11.Which of the following, if true, is the most logical completion of the argument below? The tax system of the Republic of Grootland encourages borrowing by granting its taxpayers tax relief for interest paid on loans. The system also discourages saving by taxing any interest earned on savings. Nevertheless, it is clear that Grootland's tax system does not consistently favor borrowing over saving, for if it did, there would be no--. (A) tax relief in Grootland for those portions of a taxpayer's income, if any, hat are set aside to increase that taxpayer's total savings (B) tax relief in Grootland for the processing fees that taxpayers pay to ending institutions when obtaining certain kinds of loans (C) tax relief in Grootland for interest that taxpayers are charged on the unpaid balance in credit card accounts (D) taxes due in Grootland on the cash value of gifts received by taxpayers from banks trying to encourage people to open saving accounts (E) taxes due in Grootland on the amount that a taxpayer has invested in interest-bearing savings accounts
答案：A，我选了D
21. Which of the following best completes the passage below? The unemployment rate in the United States fell from 7.5 percent in 1981 to 6.9 percent in 1986. It cannot, however, be properly concluded from these statistics that the number of unemployed in 1986 was lower than it had been in 1981 because-----. (A) help-wanted advertisements increased between 1981 and 1986 (B) many of the high-paying industrial jobs avail- able in 1981 were replaced by low-wage ser- vice jobs in 1986, resulting in displacements of hundreds of thousands of workers (C) in some midwestern industrial states, the unem- ployment rate was much higher in 1986 than it had been in 1981 (D) the total available work force, including those with and without employment, increased between 1981 and 1986 (E) the average time that employees stay in any one job dropped during the period 1981 to 1986
答案：D，我不明白work force 是如何说明unemployemnt number 的减少呢？
6. Which of the following best completes the passage below? “Government” does not exist as an independent entity defining policy. Instead there exists a group of democratically elected pragmatists sensitive to the electorate, who establish policies that will result in their own reelection. Therefore, if public policy is hostile to, say, environmental. concerns, it is not because of governmental perversity but because elected officials believe that — (A) environmentalists would be extremely difficult to satisfy with any policy, however environmentally sound (B) environmental concerns are being accommodated as well as public funds permit (C) the public is overly anxious about environmental deterioration (D) the majority of voters vote for certain politicians because of those politicians’ idiosyncratic positions on policy issues (E) the majority of voters do not strongly wish for a different policy
第三题,填入的话应该与前面的逻辑相关,前半段话表达的意思是官员是Sensitive to electorate, 就是说官员在制定政策是受到选民意志的影响.所以答案中肯定要体现这二者的关系,而答案中只有D,E有体现选民和政策,而其中D又是说为什么投票的问题,不对,所以只有E,说不是政府顽固,而是选民不想政策变化太大,从而政府政策是反映选民意志的.
