Passage 4
Questions 16 to 20 are based on the following passage:
Successful innovations have driven many older technologies to extinction and have resulted in higher productivity, greater consumption of energy, increased demand of raw materials, accelerated flow of materials through the economy and increased quantities of metals and other substances in use each person. The history of industrial development abounds with examples.
In 1870, horses and mules were the prime source of power on U.S. farms. One horse or mule was required to support four human beings a ratio that remained almost constant for many decades. At that time, had a national commission been asked to forecast the population for 1970, its answer probably would have depended on whether its consultants were of an economic or technological turn of mind. Had they been “economists”, they would probably have projected the 1970 horses or mule population to be more than 50 million. Had they been “technologists”, they would have recognized that the power of steam had already been harnessed to industry and to learn and ocean transport. They would have recognized further that it would be the prime source of power on the farm. It would have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.

最近,一些地方大学开始将方言列为某些学生的必修课程,学生们要学习当地方言,然后被评分以作为毕业的依据之一。一方面,支持此种做法的人认为,将方言列为必修课可防止其消失,从而使当地传统文化和文化多样性得以弘扬,同时城市独特的个性得以保留。另一方面,反对此种做法的人争论说,当地学生与外地学生相比有很多绝对优势,因此将方言列为必修课会引起教育不公平的问题。而且,将方言列为必修课程还会引起一些其他问题,如教材使用、师资问题和考试标准等。在我看来,方言作为传统文化不可缺少的一部分和一种交流工具,可以让学生自愿学习和使用,而不是强制完成。
