1.Between 1975 and 1985, nursing-home occupancy rates averaged 87 percent of capacity, while admission rates remained constant, at an average of 95 admissions per 1,000 beds per year. Between 1985 and 1988, however, occupancy rates rose to an average of 92 percent of capacity, while admission rates declined to 81 per 1,000 beds per year.

If the statements above are true, which of the following conclusions can be most properly drawn?

(A) The average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988.

(B) The proportion of older people living in nursing homes was greater in 1988 than in 1975.

(C) Nursing home admission rates tend to decline whenever occupancy rates rise.

(D) Nursing homes built prior to 1985 generally had fewer beds than did nursing homes built between 1985 and 1988.A

(E) The more beds a nursing home has, the higher its occupancy rate is likely to be.

有谁可以翻译一下题目啊?好像没看懂



2.Advertisement: For sinus pain, three out of four hospitals give their patients Novex. So when you want the most effective painkiller for sinus pain, Novex is the one to choose.

Which of the following, if true, most seriously undermines the advertisement’s argument?

(A) Some competing brands of painkillers are intended to reduce other kinds of pain in addition to sinus pain.

(B) Many hospitals that do not usually use Novex will do so for those patients who cannot tolerate the drug the hospitals usually use.

(C) Many drug manufacturers increase sales of their products to hospitals by selling these products to the hospitals at the lowest price the manufacturers can afford.

(D) Unlike some competing brands of painkillers, Novex is available from pharmacies without a doctor’s prescription.D

(E) In clinical trials Novex has been found more effective than competing brands of painkillers that have been on the market longer than Novex.



答案选D,为什么Novex 不用医生处方就可以从药店获得会weaken argument



3.The reason much refrigerated food spoils is that it ends up out of sight at the back of the shelf. So why not have round shelves that rotate? Because such rotating shelves would have just the same sort of drawback, since things would fall off the shelves’ edges into the rear corners.

Which of the following is presupposed in the argument against introducing rotating shelves?

(A) Refrigerators would not be made so that their interior space is cylindrical.

(B) Refrigerators would not be made to have a window in front for easy viewing of their contents without opening the door.

(C) The problem of spoilage of refrigerated food is not amenable to any solution based on design changes.

(D) Refrigerators are so well designed that there are bound to be drawbacks to any design change.A

(E) Rotating shelves would be designed to rotate only while the refrigerator door was open.

真心不知道为什么选A

4.   Technological improvements and reduced equipment costs have made converting solar energy directly into electricity far more cost-efficient in the last decade. However, the threshold of economic viability for solar power (that is, the price per barrel to which oil would have to rise in order for new solar power plants to be more economical than new oil-fired power plants) is unchanged at thirty-five dollars.

Which of the following, if true, does most to help explain why the increased cost-efficiency of solar power has not decreased its threshold of economic viability?

(A) The cost of oil has fallen dramatically.

(B) The reduction in the cost of solar-power equipment has occurred despite increased raw material costs for that equipment.

(C) Technological changes have increased the efficiency of oil-fired power plants.

(D) Most electricity is generated by coal-fired or nuclear, rather than oil-fired, power plants.C

(E) When the price of oil increases, reserves of oil not previously worth exploiting become economically viable.

Threshold=solar cost-oil cost, unchanged ,since solar cost下降了

为什么不选A呢,oil cost 下降了,也会导致结果

1.occupancy rate床位空置率和admission rate入院率
2.一般情况下:3/4的医院开N这种药→治疗sinus;现在:选取最有效的治疗sinus的药;结论:用N就行
AC无关,BE加强。D是提供了一个干扰因素:医院选N是因为N是非处方药。(不一定是效果好,如同E所讲)
3.BE无关,D我认为是削弱,AC我没法区分,不知道这是哪里的题
4.选A的话,solar和oil-fire的成本都降了,再加上本来solar就有的优势,the threshold of solar power 就应该change了,这和题目是反得

个人意见,非NN,仅供参考~

1) is a math problem. A) can explain the two conditions stated in the passage.

恩,第一题弄懂了,第二题也懂了,谢了!

3.4还是米想清楚哦,是不是我太笨了呀

第四题C肯定是对的,但是A是不是因为dramatically的错误啊?它会使得threshold变化的,求指教啊

哈哈,我明白第三题是什么意思了 premise:1.冰箱里有些食物会烂掉,因为它们被遮挡在后面了 2.圆形可以转动的shelf会让冰箱里食物掉下来  conclusion:即使把shelf换成圆形可以转动的也不行
Q:作者提出结论的presupposition是什么?
A.冰箱的内部不可以作成圆柱体的, 因为如果是圆柱体的,食物在圆形shelf上就不会掉下来了

第四题说的是两个efficiency的关系,你说oil的cost下降了,oil-fired的efficiency就会变了吗?不一定吧?efficiency又不是只和oil的cost相关。

因为a选项有两种可能性吧。一种就是油价下来了,但是cost-efficiency还是不变。一种是油价不变,cost-efficiency提高了。因此这个选项没有C好,选项C明明白白地告诉你油价不变的原因是因为cost-efficiency提高了~
