译：有些学生需要老师像医生开药一样每天给他们规定一定量的信息。

　　others need challenge and a high degree of responsibility for the design of their own work. But for too long， teachers have insisted that there is one best way to teach and learn， even though they have disagreed about what that way is.⑿

　　12.that 引导宾语从句，even though 引导让步状语从句，

　　disagree about 意见不合，有分歧

　　译：但长期以来，尽管老师们对什么是最好的教学方法存在分歧，却坚持认为只有一种最好的教学方法。

　　A century ago， the greatest majority of Americans lived in communities so small that only one one -room schoolhouse was within walking distance of small children. Then there had to be “one right method” for everybody to learn.

　　Today the great majority of pupils in the United State（and all developed countries） live in big cities with such density that there can easily be three or four elementary schools -as well as secondary schools within each child‘s walking or bicycling distance. This enables students and their parents to choose between alternative routes to learning offered by competing schools.

　　Indeed， competition and choice are already beginning to infiltrate the school system. Private schools and colleges have shown an unusual ability to survive and develop during a period of rising costs and dropping enrollments elsewhere. All this present， of course， a true threat to the public school establishment.

　　But economics， student needs and our new understanding of how people learn are bound to break the traditional education monopoly just as trucks and airplanes broke the monopoly of railroads， and computers and “chips” are breaking the telephone monopoly.⒀

　　13.be bound（bind 的过去分词）to （必然）

　　bind（动词——绑）

　　该句的主语是economics， student needs and our new understanding，其中 economics 应该理解为“经济因素”。

　　to break the monopoly 意为：“打破垄断”

　　just as 引导方式状语从句

　　译：但是经济因素、学生的需要以及我们对如何学习的新观点都必然要打破传统教育的垄断，正如卡车和飞机打破了铁路的垄断、计算机与芯片正在打破电话的垄断一样。

　　In the next 10 or 15 years we will almost certainly see strong pressures to make schools responsible for thinking through what kind of learning methods are appropriate for each child.

　　We will almost certainly see great pressure， from parents and students alike， for result-focused education and for accountability in meeting objectives set for inspanidual students. ⒁

　　14.result（名词——结果、效果）

　　focus （动词——集中）

　　accountability in 意为：“在…方面的责任感 ”

　　set for inspanidual students 过去分词短语作后置定语，修饰objectives 为各个学生制定的目标

　　本句难理解的难点主要在介词和名词的搭配：great pressure … from … for … and for

　　译：我们几乎肯定还会遇到来自父母及学生同样巨大的压力，要求讲究教育实效，要认真负责地实现为各个学生制定的教育目标。

　　The continuing professional education of highly educated adults will become a third tier in addition to undergraduate and professional or graduate work. Above all， attention will shift back to schools and education as the central capital investment and infrastructure of a “knowledge society.”
