    正确答案：B,A,B,D,C
    试题71、72、73、74、75分析计算机将变得更加先进，也将变得更容易使用。提高了处理速度将使计算机变得更加容易操作。虚拟现实是一种用人的感官与计算机交换的技术,也将更有利于人和计算机接口。另外，奇异的模型正在开发中，包括使用生活有机体的生物计算，使用具有特定性能的分子计算和使用DNA（遗传的基本单位）来存储数据和进行操作等技术。这些可能是未来计算平台的例子，到目前为止，计算机的能力有限，并且局限于严格的理论。科学家们也正是因为小型化的嵌入式芯片电路的物理限制而研究新的技术。也有晶体管产生热量方面的限制，哪怕是最小的晶体管。参考答案（71）B（72）A（73）B（74）D（75）C
