    A.empirical
    B.real
    C.practical
    D.theoretical

    答案:D
    解析:
    题意想要表达的意思是只限于理论方面的研究,正确答案为D。Theoretical:理论的。附(参考翻译):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不计算机迚行交互的一种技术,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。

    What can be inferred from the example of the ant-lion in the first paragraph?
    A

    Instincts of animals can lead to unreasonable reactions in strange situations.

    B

    When it is engaged in a chain actions it cannot be interrupted.

    C

    Environment and heredity are two supplementary factors in the evolution of insects.

    D

    Along the lines of evolution heredity becomes less and environment more important.


    正确答案: A
    解析:
    本题可参照第一段中间一句话“if such a lonely animal is engaged upon a chain of actions and is interrupted, it either goes on vainly with the remaining actions ... or dies in helpless inactivity”,从中可知,蚁狮会执著地做出本能的反应。因此B项为正确答案。
