以往几个世纪人口的增长并不能证明人口会无限地直线向上增长直到毁灭的地步。相反地，人口统计史料

证明人口的增长完全不是一成不变的。若技术革新的成果开始减少，从250到350年前就在西方开通出现的并且目前还在继续的人口迅速增长可能也会放慢。当然，当前的知识革命也许会持续下去而无法预见其未来。无论如何，与那种认为人口以几何级数持续增长的观点相反，从长远的观点来说，人口可望受到生产力的调节。接受了这一观点，人口的增长就右以被看成是经济进步和人类胜利的标志，而不是社会衰败的标志。

ish primary and secondary schools, for example, the teacher is the primary provider of required information and rote learning plays an important role in the acquisition of this information. British school leavers who then proceed to university face a new set of academic norms and expectations. Although memorization is still required, far greater emphasis is placed on the critical evaluation of received information.

听力原文：Some people are inconsiderate drivers. In the city, they will often stop right in

the middle of the street while looking for a certain home or landmark. Other drivers will suddenly slow down at a crossroad to make a right or left turn. Still others never wait for their turns in bottleneck situations where the cars in two lanes must merge alternatively into one. Perhaps the most inconsiderate drivers are those who throw trash out their windows, which spoils the pleasure of driving as well as the environment.

第9题

Innovation can come from without as well as within. Apple is widely assumed to be an innov

ator, locking its engineers away to cook up new ideas and basing products on their moments of inspiration. In fact, its real skill lies in stitching together its own ideas with technologies from outside and then wrapping the results in elegant software and stylish design. Apple is, in short, an orchestrator and integrator of technologies, unafraid to bring in ideas from outside but always adding its own twists.

This approach, known as "network innovation", is not limited to electronics. It has also been embraced by companies such as Procter ＆ Gamble, BT and several drugs giants, all of which have realized the power of admitting that not all good ideas start at home. Making network innovation work involves cultivating contacts with start-ups and academic researchers, constantly scouting for new ideas and ensuring that engineers do not fall prey to "not invented here" syndrome, which always values in-house ideas over those from outside.
