The following appeared in a letter to the editor of a popular science and technology magazine. “It is a popular myth that consumers are really benefiting from advances in agricultural technology. Granted — consumers are, on the average, spending a decreasing proportion of their income on food. But consider that the demand for food does not rise in proportion with real income. As real income rises, therefore, consumers can be expected to spend a decreasing proportion of their income on food. Yet agricultural technology is credited with having made our lives better.” 人们普遍错误的认为消费者真的能从农业技术的进步中获益。姑且认为平均而言，消费者的食品支出占他们收入的比例的确越来越少，但是考虑到对食品的而需求并没有随着实际收入的增长而增加---随着实际收入的增加，消费者预期用在食品上的收入比例本来就会有减少。即使如此，人们依然认为，是农业技术使我们的生活越来越好
还有第60 60. The following appeared as part of an article in a popular science magazine. “Scientists must typically work 60 to 80 hours a week if they hope to further their careers; consequently, good and affordable all-day child care must be made available to both male and female scientists if they are to advance in their fields. Moreover, requirements for career advancement must be made more flexible so that preschool-age children can spend a significant portion of each day with a parent.” 请问这道题在扯些什么啊 该怎么攻击
