(5)

选项 A、developments
B、advantages
C、limitations
D、improvements

答案C

解析 计算机将越来越高级且易于使用。识别速度的提高将使计算机的操作更加容易。虚拟现实是一种用人的所有感官与计算机相互的技术,它也将有助于改善人类和计算机的交互。其他方面,奇异的计算模型都正在开发巾,包括使用生物体的生物计算、使用具有特殊性质分子的分子计算及使用DNA来存储数据和执行操作的计算。到目前为止,这些可能的未来计算平台都受到性能上的限制或是严格理论化的。科学家研究它们,因为嵌入在硅中小型化的电路存在物理限制,也存在着和最微小的晶体管产生的热量相关的限制。
