问题 Computers will become more advanced and they will also become easier to use.Improved speed recognition will make the operation of a computer easier.Virtual reality (虚拟现实),the technology of  (1)  with a computer using all of the human senses,will alsocontribute to better human and computer  (2)  .Other,exotic(奇异的)models ofcomputation are being developed,including biological computing that uses living organisms,molecular computing that uses molecules with particular  (3)  ,and computing that usesDNA,the basic unit of heredity(遗传),to store data and carry out operations.These areexamples of possible future computational platforms that,so far,are limited in abilities or arestrictly  (4)  .Scientists investigate them because of the physical limitations ofminiaturizing circuits embedded in silicon.There are also  (5)   related to heat generatedby even the tiniest of transistors.
(5)

选项 A、developments
B、advantages
C、1imitations
D、improvements

答案C

解析 本题考查对英语资料的阅读理解。
    计算机将会变得越来越高级而且更易于使用。识别速度的提升将使计算机的操作更加容易。虚拟现实是使用人的感觉与计算机进行交互的一种技术,它也会使得人机界面更好。另外,各种新奇的计算模型正在不断发展,如生物计算使用人的器官、分子计算使用具有特定属性的分子、DNA计算采用遗传的基本单元来存储数据和执行操作。到目前为止,这些都还属于未来计算平台,能力非常有限,并且只限于理论方面的研究。科学家们之所以研究这些计算模型,原因在于嵌入硅片中的微型芯片的体积的局限性,以及即使是非常小的晶体管所产生的热量方面的局限性。
