请教OG-122

MWY

这道题以前问过，但是还是没能解释我所不明白的地方，所以再问一次，原题如下：
122. When people evade income taxes by not declaring taxable income, a vicious cycle results.Tax evasion forces lawmakers to raise income tax rates, which causes the tax burden on nonevading taxpayers to become heavier. This, in turn, encourages even more taxpayers to evade income taxes by hiding taxable income.
The vicious cycle described above could not result unless which of the following were true?
(A) An increase in tax rates tends to function as an incentive for taxpayers to try to increase their pretax incomes.
(B) Some methods for detecting tax evaders, and thus recovering some tax revenue lost through evasion, bring in more than they cost, but their success rate varies from years to year.
(C) When lawmakers establish income tax rates in order to generate a certain level of revenue,they do not allow adequately for revenue that will be lost through evasion.
(D) No one who routinely hides some taxable income can be induced by a lowering of tax rates to stop hiding such income unless fines for evaders are raised at the same time.
(E) Taxpayers do not differ from each other with respect to the rate of taxation that will cause  them to evade taxes.
    我不明白的地方是问题，我记得not A unless B 的推理是A可以推出B吧？放到这里就是the vicious cycle described could  result 能推出C答案这个说法,这好像说不通吧？我错在哪儿呢？

提干的意思实际上是问以下那个选项为assumption？

显然答案是C

2楼的请翻译一下C，谢谢。

lawmakers 制定所得税率时要考虑税收总收入不变 (more tax evasion)=> more tax from tax payers => increase tax rates => encourage more tax evasions

(D) No one who routinely hides some taxable income can be induced by a lowering of tax rates to stop hiding such income unless fines for evaders are raised at the same time.

笨笨问笨题，D怎么翻译呢？

以下是引用蓝夕叶子在2005-5-18 21:38:00的发言：

(D) No one who routinely hides some taxable income can be induced by a lowering of tax rates to stop hiding such income unless fines for evaders are raised at the same time.

笨笨问笨题，D怎么翻译呢？

偶也非NN，不过说出自己的理解大家讨论：“除非对于逃税者的处罚加重，否则对于那些平常喜欢隐藏纳税收入（即逃税）的人来说，仅仅通过降低税率，是不要指望会促使他们把那些应该纳税的部分申报出来缴税的”！

完全是意译，希望没有歪曲愿意！

great，thanks，lonelywalker123！

谁来解释一下Ａ，没看懂ＯＧ中的解释，多谢了

A的意思是：税率的增加往往导致人们去尽力增加他们自己的税前工资。



这样一来，工资涨了，自己不会去逃税了，也就against the cycle了。所以OG的解释是：Increasing in pretax
incomes (income A) would tend to work against perpetuation of the cycle.
