23.现在的GPS只能告诉你前方交通拥堵。但我们的科学家正在运用交通预测技术，通过了解人们的驾驶方式，掌握火车飞机的抵达时间，检测并预测交通情况，从而给每个人个性化的通勤指令。这样我们就可以预测并防止交通拥堵的发生，而不是等到发生堵塞之后再绕道而行，每个人就都能畅通无阻了。
参考译文：Right now you know your GPS might be able to tell you that there is congestion up ahead. Well, our scientists are now using traffic prediction technology, not just detection, but prediction, so that by knowing everyone's driving patterns, and knowing about the sort of arrival times of trains and planes, etc, we'll be able to give everyone personalized commute instructions. So that rather than just wait for congestion to happen and then wrap people around it, we'll be able to anticipate and prevent that congestion on the same roadways and everyone will move more smoothly.
24.随着本世纪时光的流逝，有待于解决的问题范围日益扩大.日益复杂以及不同学科日益增长的相互联系，这使得在许多情况下一个科学家不可能单独研究处理大量的新资料数据.新技术和新仪器设备，而这三者都是精确有效的进行研究所需要的。
参考译文：As the century developed ,the increasing magnitude and complexity of the problems to be solved and the growing interconnection of different disciplines made it impossible, in many cases, for the individual scientist to deal with the huge mass of new data, techniques and equipment that were required for carrying out research accurately and efficiently.
