United States hospitals have traditionally relied primarily on revenues from paying patients to offset losses from unreimbursed care.  Almost all paying patients now rely on governmental or private health insurance to pay hospital bills.  Recently, insurers have been strictly limiting what they pay hospitals for the care of insured patients to amounts at or below actual costs.

Which of the following conclusions is best supported by the information above?

(A) Although the advance of technology has made expensive medical procedures available to the wealthy, such procedures are out of the reach of low-income patients.
(B) If hospitals do not find ways of raising additional income for unreimbursed care, they must either deny some of that care or suffer losses if they give it.
(C) Some patients have incomes too high for eligibility for governmental health insurance but are unable to afford private insurance for hospital care.
(D) If the hospitals reduce their costs in providing care, insurance companies will maintain the current level of reimbursement, thereby providing more funds for unreimbursed care.
(E) Even though philanthropic donations have traditionally provided some support for the hospitals, such donations are at present declining.


我对文章意思的理解：美国医院以前主要都从付费病人那里得到收入来抵消那些不偿还的care带来的损失。几乎所有的付费病人现在依赖政府或者私人健康保险去支付医院账单。近来，保险公司严格限制他们给医院病人的保险费用低于或者等于实际的费用

问。下面哪个由上文支持。

答案选择B- -哎完全不能明白题目的意思和选项的意思-0 -

43.    (33475-!-item-!-188;#058&006874)

Paint on a new airliner is usually applied in two stages:  first, a coat of primer, and then a top coat.  A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat.  Using the new process instead of the old process increases the price of a new aircraft considerably.

Which of the following, if true, most strongly indicates that it is in an airline's long-term economic interest to purchase new airliners painted using the new process rather than the old process?

(A) Although most new airliners are still painted using the old process, aircraft manufacturers now offer a purchaser of any new airliner the option of having it painted using the new process instead.
(B) A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.
(C) A single layer of the new coating provides the aluminum skin of the airliner with less protection against corrosion than does a layer of primer of the usual thickness.
(D) Unlike the old process, the new process was originally invented for use on spacecraft, which are subject to extremes of temperature to which airliners are never exposed.
(E) Because the new coating has a viscosity similar to that of a traditional top coat, aircraft manufacturers can apply it using the same equipment as is used for a traditional top coat.

文章意思：在客机上油漆，有两个阶段：先是一层primer，然后top层。新的过程不要primer，但是用两层一样的新的developed coating，每层都有一样的厚度和重量，就像传统的top coat。用新的取代旧的使新的航行器的价钱上升。

为什么用新的是符合长远经济利益的呢？

答案是B，我想选择C。

they must either deny some of that care(unreimbursed care) or suffer losses if they give it.他们就必须拒绝那些不偿还的治疗，或者给予不偿还的治疗则要承担损失

医院的费用以前靠病人付， 现在都是保险公司付。现在保险公司也不付。
言下之意，医院费用就没谁管了，那就得医院自己想办法酬钱，否则就只好要么不提供治疗，如果治疗的话就只好赔本了。

呃~72题还是不大明白啊>_<~~不知道能不能翻译一下文章的意思和选项的意思呢？谢谢啊。。B中的那个deny是怎么回事呢。。

大牛不在，我来试着回答一下。
第72题：B选项就是短文第一句话的另一种说法啊。A、C、E都出现了新概念，是无关选项；D从文中推不出来，保险公司没有那么傻，如果医院降低收费，他们也会降低赔偿标准的，这点可以从保险公司严格限制费用支出看出来。
第43题：B选项说新方法可以降低飞机的自重，从而可以增加载重，这样就可以多拉些人或者货物，自然可以有更多的经济利益；C正好相反，是鼓吹老方法比新方法好。
