计算机发展的另一个趋势是“第五代”计算机的研制工作，亦即研制可以解决复杂问题而且其解决方法或许最终会与“创造性的”这一形容名副其实的计算机，理想的目标是真正的人工智能。
35. 词汇：mimic
One important parallel-processing approach is the neural network, which mimics the architecture of the nervous system.
翻译：一种重要的并行处理方法是模仿神经系统结构的神经网络。
?approach---方法 ?mimic---模仿

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 be classified as mainframes, minicomputers, workstations, or microcomputers.
28
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, 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.
