ved in the study of astronomy 第 43篇答案： ACDAD 第 44篇： (Unit 11, Passage 4) The promise of finding longterm technological solutions to the problem of world food shortages seems difficult to fulfill. Many innovations that were once heavily supported and publicized have since fallen by the wayside. The proposals themselves were technically feasible, but they proved to be economically unviable and to yield food products culturally unacceptable to their consumers. 中国最大的资料库下载 中国最大的资料库下载 One characteristic mon to unsuccessful food innovations has been that, even with extensive government support, they often have not been technologically adapted or culturally acceptable to the people for whom they had been developed. A successful new technology, therefore, must fit the entire social cultural system in which it is to find a place. Security of crop yield, practicality of storage, and costs are much more significant than previously been realized by the advocates of new technologies. The adoption of new food technologies depends on more than these technical and cultural considerations。 economic factors and governmental policies also strongly influence the ultimate success of any innovation. Economists in the AngloAmerican tradition have taken the lead in investigating the economics of technological innovation. Although they exaggerate in claiming that profitability is the key factor guiding technical change—they pletely disregard the substantial effects of culture—they are correct in stressing the importance of profits. Most technological innovations in agriculture can be fully used only by large landowners and are only adopted if these profitoriented business people believe that the innovation will increase their ines. Thus, innovations that carry high rewards for big agribusiness groups will be adopted even if they harm segments of the population and reduce the availability of food in a country. Further, should a new technology promise to alter substantially the profits and losses associated with any production system, those with economic power will strive to maintain and improve their own positions. Therefore, although technical advances in food production and processing will perhaps be needed to ensure food availability, meeting food needs will depend much more on equalizing economic power among the various segments of the populations within the developing countries themselves. passage mentions all of the following as factors important to the success of a new food crop except the ___. of storage of the crop. of the crop yield. of the crop’s protein. acceptability of the crop. author suggests that, in most emerging countries, extensive government intervention acpanying the introduction of a food innovation will ___. be sufficient to guarantee the financial success of the innovation. necessary to ensure that the benefits of the innovation will be spread throughout the society. occur only when the innovation favors large landowners. cost the country more than will be earned by the innovation. first paragraph of the passage best supports which of the following statements? much publicity can harm the chances for the success of a new food innovation. that produce culturally acceptable crops will generally be successful. foodproduct innovation can be technically feasible and still not be economically viable. 中国最大的资料库下载 中国最大的资料库下载 is difficult to decide whether a foodproduct innovation has actually been a success. author provides a sustained argument to uphold which of the following assertions? is neither necessary nor sufficient for a new technology to be adopted. is the key factor guiding technological change. factors and governmental policies strongly influence the ultimate success of any innovation. carrying high rewards for big agribusiness groups harm the poor. primary purpose of the passage is to discuss the ___. of assessing the extent of the world food shortage. of applying technological solutions to the problem of food shortages. of introducing a new food technology into a developing country. of the new technological innovations in the area of food production. 第四十四篇答案： CBCCB 第四十五篇： (Unit 12,Passage 1) What most people don’t realize is that wealth isn’t the same as ine. If you make $ 1 million a year and spend $ 1 million, you’re not getting wealthier, you’re just living high. Wealth is what you accumulate, not what you spend. The most successful accumulators of wealth spend far less than they can afford on houses, cars, vacations and entertainment. Why? Because these things offer little or no return. The wealthy would rather put their money into investments or their businesses. It’s an attitude. Millionaires understand that when you buy a luxury house, you buy a luxury life –style too. Your property taxes skyrocket, along with the cost of utilities and insurance, and the prices of nearby services, such as grocery stores, tend to be higher. The rich man’s attitude can also be seen in his car. Many drive old unpretentious sedans. Sam Walton, billionaire founder of the Wal – Mart Store, Inc., drove a pickup truck. Most millionaires measure success by worth, not ine. Instead of taking their money home, they plow as much as they can into their businesses, stock portfolios and other assets. Why? Because the government doesn’t tax wealth。 it taxes ine you bring home for consumption, the more the government taxes. The person who piles up worth fastest tends to put every dollar he can into investments, not consumption. All the while, of course, he’s reinvesting his earnings from investments and watching his worth soar. That’s the attitude as well. 中国最大的资料库下载 中国最大的资料库下载 The best wealthbuilders pay care。
