14. Which of the following, if true, best completes the argument below? Comparisons of the average standards of living of the citizens of two countries should reflect the citizens’ comparative access to goods and services. Reliable figures in a country’s own currency for the average income of its citizens are easily obtained. But it is difficult to get an accurate comparison of average standards of living from these figures, because______ (A) there are usually no figures comparing how much of two different currencies must be spent in order to purchase a given quantity of goods and services (B) wage levels for the same job vary greatly from country to country, depending on cultural as well as on purely economic factors (C) these figures must be calculated by dividing the gross national product of a country by the size of its population (D) comparative access to goods and services is only one of several factors relevant in determining quality of life (E) the wealth, and hence the standard of living, of a country’s citizens is very closely related to their income KEY IS A
17. Since 1975 there has been in the United States a dramatic decline in the incidence of traditional childhood diseases such as measles. This decline has been accompanied by an increased incidence of Peterson’s disease, a hitherto rare viral infection, among children. Few adults, however, have been affected by the disease. Which of the following, if true, would best help to explain the increased incidence of Peterson’s disease among children? (A) Hereditary factors determine in part the degree to which a person is susceptible to the virus that causes Peterson’s disease. (B) The decrease in traditional childhood diseases and the accompanying increase in Peterson’s disease have not been found in any other country. (C) Children who contract measles develop an immunity to the virus that causes Peterson’s disease. (D) Persons who did not contract measles in childhood might contract measles in adulthood, in which case the consequences of the disease would generally be more severe. (E) Those who have contracted Peterson’s disease are at increased risk of contracting chicken pox. KEY IS C
14.Comparisons of the average standards of living of the citizens of two countries should reflect the citizens’ comparative access to goods and services这是结论。注Reliable figures in a country’s own currency for the average income of its citizens are easily obtained意这里用的前提是比较获得的商品和服务。Reliable figures in a country’s own currency for the average income of its citizens are easily obtained。指出收入的数字有了。但是总结论是很难比较the average standards of living of the citizens of two countries 。那么原因是购买这一环节很难比较。收入－－－购买－－－－商品和服务。中间链条有问题。
Comparisons of the average standards of living of the citizens of two countries should reflect the citizens’ comparative access to goods and services这句话怎么理解，好像是comperaions of standards 推出 citizen's access to goods and service意思好像反了
