【正文】 ssumption is that if people who have money expect prices to go up, they will hasten to they expect prices to go down, they will postpone research surveys have shown that this is not always expectations of ine increases may not stimulate typical attitude was expressed by the wife of a mechanic in an interview at a time of rising prices.“In a few months,” she said, “we’ll have to pay more for meat and milk, we’ll have less to spend on other things.” Furthermore, the rise in prices that has already taken place may be resented and buyer’s resistance may be is shown by the following typical ment: “I just don’t pay these prices, they are too high.”Traditional assumptions should be investigated carefully, and factors of time and place should be investigations mentioned above were carried out in conducted at the same time in Great Britain, however, yielded results that were more in agreement with traditional assumptions about saying and spending condition most conductive to spending appears to be price prices here have been stable and people have bee accustomed, to consider them “right” and expect them to remain stable, they are likely to , it appears that the mon business policy of maintaining stable prices with occasional sales or discounts is based on a correct understanding of consumer example of the mechanic’s wife is intend to show that in times of rising prices, with declining ine tend to buy less with stable ine tend to borrow less with increasing ine tend to buy more with money also tend to buy less in investigations in Britain indicate factors should be taken into account in Britain behave in the same way as those in America stability results from a correct understanding of consumer psychology discounts and sales are necessary to the passage people tend to buy more when are expected to go up are expected to go down don’t change policy remains unchanged best title of the passage is ’s Purchasing Power between Ine and Purchasing Power Assumptions in Consumer Behavior to the passage, what does the author think of the traditional assumptions about consumer behavior? assumptions are not always are in are in consistent with the findings in assumptions are not at all 2 Directions: After reading the following passage, you will find 5 questions or unfinished statements( to ).For each question or statement there are 4 choices marked A, B, C and should make the correct choice and write the corresponding letter on the Answer is evidence that the usual variety of high blood pressure is, in part, a family families have similar genes as well as similar environment, family diseases could be due to shared genetic influences, to shared environmental factors, or to some years, the role of one’s environmental factor monly shared by families, namely, dietary salt, has been studied at Brookhaven National studies suggest that chronic excess salt ingestion can lead to high blood pressure in man and individuals, however, and some rats consume large amounts of salt without developing high blood matter how strictly all environmental factors were controlled in these experiments, some saltfed animals never develop hypertension where—as a few rapidly developed very severe hypertension followed by early marked variations were interpreted to result from differences in genetic mating in successive generations only those animals that failed to develop hypertension from salt ingestion, a resistant strain(the“R” strain)has been evolved in which consumption of large quantities of salt fails to influence the blood pressure contrast, by mating only animals that quickly develop hypertension from salt, a sensitive strain(the“S” strain)has also been availability of these two strains permits investigations not heretofore provide a plausible laboratory model on which to investigate some clinical aspects of the human prototypes of important, there might be the possibility of developing methods by which genetic susceptibility of human beings to high blood pressure can be defined without waiting for its statement relates the main idea of this passage? salt is added to their diets, rats and men react in much the same near future will see a cure for high blood research has shown that high blood pressure is a result of salt in the tendency toward high blood pressure may be a hereditary study of the effects of salt on high blood pressure was carried members of the same family tend to use similar amounts of salt explore the longterm use of a sodiumbased substance it was proved that salt caused high blood pressure of the availability of chemically pure salt and its derivatives is implied that the main difference between “S” and “R” rats is for Sodium of mating to salt of blood the experiments, was an increase in the human consumption of salt eaters have bad health conditions environment was strictly monitored blood pressure was easier put under control the results of the research discussed in this article, the most beneficial might early identification of potential high blood pressure victims of diets free of salt early cure for high blood pressure of genetic agents that cause high blood pressureTask 3 Directions: After reading the following passage, you will find 5 questions or unfinished statements( to ).For each question or statement there are 4 choices marked A, B, C and should make the correct choice and write the corresponding letter on the Answer two hundred years ago, Adam Smith introduced some ideas, which brought about a world we enjoy a high standard of living in modern society, we owe much to this Scottish economist and we enjoy driving in beautiful cars, wearing fashionable shoes, or flying away to distant places for exciting holidays, we should perhaps pay thanks to the man who made it all was Adam Smith’s contribution? Like so many ideas, which have surprising effects, his was a simple watched workers practising their craft of pin man
