以下是引用sigrid920在2006-12-25 10:17:00的发言：早上好啊, 刚赶在网上看到国内过节好热闹哦~~呵呵
偶今天看完了另一半逻辑~~有两个题目需要求证一下~!
The total market value of real estate in Altonville has steadily declined over the past four years. This decline has meant that the overall figure on which the city’s property tax is based—the assessed value of that real estate—has also declined. The percentage of assessed value that was paid as property taxes to the city, however, did not change from year to year during this period.
The information above most strongly supports which of the following?
- The percentage of Altonville’s yearly revenue that comes from money collected in property taxes did not change over the past four years.
- The percentage of Altonville’s yearly revenue that comes from money collected in property taxes has declined steadily over the past four years.反对了题目条件, 题目说了%每年都没有变.
- The amount of revenue that Altonville collected from property taxes was lower last year than it was four years ago.
- During the past four years, Altonville officials increased tax rates on other sources of revenue such as retail sales and business profits.
- Altonville will soon require property owners to pay a higher percentage of the assessed value of their property as property tax.
财产税的基数减少,(等于说财产税收变少), 但是财产税占总税收的%没有变, 推论,
总税收减少了. 好像说分子减少, 但是总%没变, 那肯定是分母也减少了. 但是没有这个选项.Compare with an old edition of this question listed below. There are many tiny changes in the main body of the question and its answer choices. 这个题目的选项挺怪的, 我觉得(A)(C)都对.The percentage of assessed value that was paid as property taxes to the city did not change from year to year during this period. 不就是(A)的改写吗?
气4偶了，写完了要发表的时候网断了，倒。。。只得重写。。。>.<
丽香，这题不怪，关键是要理解那个The percentage of assessed value that was paid as property taxes的意思，其实这个东东就是中文的“税率”，鬼子不说“tax rate”，而故意绕着圈来说，就是要蒙你的，要识破它的阴谋~~
如你所说，税基不变，税率减少，唯一的结果－－tax revenue减少,C~

28. GWD28-Q28:
Which of the following most logically completes the argument?
A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants. Agronomists studying the herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert. Possibly, therefore, the herb’s high histidine production is what allows it to grow in metal-rich soils, a hypothesis that would gain support if ______.
- histidine is found in all parts of the plant—roots, stem, leaves, and flowers
- the herb’s high level of histidine production is found to be associated with an unusually low level of production of other amino acids
- others of the closely related group of plants are also found to produce histidine in large quantities
- cultivation of the herb in soil with high concentrations of the metals will, over an extended period, make the soil suitable for plants to which the metals are toxic
- the concentration of histidine in the growing herb declines as the plant approaches maturity
Answer:
此题目争议了还久, 向JOJO求证一下, 我选(C)
在CDE中争论不休，但个人认为E一定不对，因为herb成不成熟与它能否在高铁的环境生存根本无关，原文亦无说明herb产生histidine是在幼年期，亦无说明成熟了以后就不需要histidine来抵抗高铁的环境，所以不对。
原本也选的C，现在看完讨论觉得D比较有道理，偶的看法是：
C说：others of the closely related group of plants are also found to produce histidine in large quantities，herb是属于这个group没错，而这个group也是能 thrive in soil with high concentrations of metals，问题是C并没有指出其他能产生大量histidine的植物是在高铁环境生存时产生这些histidine啊，有可能它们在任何环境下都会产生这些histidine呢？如果是这样的话就变成削弱啦！
反观D，因为herb产生的histidine能令金属铁产生惰性，从而不影响植物的生长，那么在有herb的环境下一般植物自然亦能生长啦，因为原本很toxic的metal都没有影响了，所以D为答案。
