1.     Child’s World, a chain of toy stores, has relied on a “supermarket concept” of computerized inventory control and customer self-service to eliminate the category of sales clerks from its force of employees. It now plans to employ the same concept in selling children’s clothes.

The plan of Child’s World assumes that

(B) personal service by sales personnel is not required for selling children’s clothes successfully

(C) the same kind of computers will be used in inventory control for both clothes and toys at Child’s World

答案是c为什么不能选b

17.    Lists of hospitals have been compiled showing which hospitals have patient death rates exceeding the national average. The data have been adjusted to allow for differences in the ages of patients.

Each of the following, if true, provides a good logical ground for hospitals to object to interpreting rank on these lists as one of the indices of the quality of hospital care EXCEPT:

(A) Rank order might indicate insignificant differences, rather than large differences, in numbers of patient deaths.

(C) Patients who are very old on admission to a hospital are less likely than younger patients to survive the same types of illnesses or surgical procedures.

为什么要选c不能选a

tina mm，你能不能把题目贴全了？而且最好不要把答案嵌在题目里，这样我们可以在不被干扰的情况下把你的题目作一下，再给出解释，否则思路都被你嵌在题目里的答案影响了。另外，我觉得你好多题目答案好象不太对，你仔细对照过吗？比如这里1我觉得答案就是B

(A) Rank order might indicate insignificant differences, rather than large differences, in numbers of patient deaths.

(B) Hospitals that keep patients longer are likely to have higher death rates than those that discharge patients earlier but do not record deaths of patients at home after discharge.

(C) Patients who are very old on admission to a hospital are less likely than younger patients to survive the same types of illnesses or surgical procedures.

(D) Some hospitals serve a larger proportion of low-income patients, who tend to be more seriously ill when admitted to a hospital.

(E) For-profit hospitals sometimes do not provide intensive-care units and other expensive services for very sick patients but refer or transfer such patients to other hospitals.

1，原文里说要去掉SALES CLERK，卖儿童衣服也要用同样的方法去掉SALES CLERK，所以只有B说，店家的假设是卖儿童衣服不需要员工。否则怎么能去掉SALES CLERK呢？

17，C选项没有说明医院之间的区别啊，每个医院都可能收老人，收年轻人。而A选项说明RANK有问题，根本不能正确地指出死亡的数目，当然医院们有理由反对这个RANK了。

我还是不太懂17题

a选项不是说排名可能只有很小的差异在病人死掉的数目上,所以排名是正确的,所以没有object to interpreting rank

对吗

tina_aya

可以在帮我解释一下第17题吗,thanks

dashasha

17题A的意思是RANK不同所代表的病人死掉的数目差异非常小，所以这个RANK没有意义啊。
