III. Fill in each of the blanks with one of the words given in the following list,
making
changes if necessary:
We can define a computer as a device that accepts input, processes data, stores
data, and
produces output. According to the mode of processing, computers are either
analog or digital.
They can also be classified as mainframes, minicomputers, workstations, or
microcomputers.
All else (for example, the age of the machine) being equal, this categorization
provides some
indication of the computer’s speed, size, cost, and abilities.
Ever since the advent of computers, there have been constant changes.
First-generation
computers of historic significance, such as UNIVAC (通用自动计算机),
introduced in the
early 1950s, were based on vacuum tubes. Second-generation computers,
appearing in the
early 1960s, were those in which transistors replaced vacuum tubes. In
third-generation
computers, dating from the 1960s, integrated circuits replaced transistors. In
fourth-generation
computers such as microcomputers, which first appeared in the mid-1970s,
large-scale
integration enabled thousands of circuits to be incorporated on one chip.
Fifth-generation
computers are expected to combine very-large-scale integration with
sophisticated approaches
to computing, including artificial intelligence and true distributed processing.
IV. Translate the following passage from English into Chinese:
计算机将变得更加先进，也将变得更加容易使用。语音识别的改进将使计算机的操作 更加容易。虚拟现实，即使用所有人类官能与计算机进行交互的技术，也将有助于创建更好的人机接口。人们正在开发其他的奇异计算模型，包括使
用生物机体的生物计算、使用具有特定属性的分子的分子计算，以及使用遗传基本单位DNA（脱氧核糖核酸）存储数据和执行操作 的计算。这些都是可能的未来计算平台的例子，而它们迄今还能力有限或完全属于理论范畴。科学家们研究它们，是因为嵌入硅中的电路的微小型化 受到物理限制。还有一些限制与甚至最微小的晶体管也会产生的热量有关。
