在沙漠种一辆汽车每天行200千米，汽车种装了能够行驶24天的油，跑一定的路后，必须按原路返回，甲、乙两辆车进沙漠，为了能够使甲车到更远的地方，乙车行了一段路程后，把部分汽油给甲车，剩下的汽油可以使乙车返回，甲车最多行多少路程？

答案

（24-2×1）×200，

=（24-2）×200，

=22×200，

=4400（千米）．

答：甲车最多行4400千米．

For each blank, choose the best answer from the four choices and write down on the answer sheet.

It is claimed that Al applications have moved from laboratories to the real world. However, conventional von Neumann computers are (1) for Al applications, because they are de- signed mainly for numerical processing. In a larger yon Neumann computer, there is a larger ratio of memory to processing power and consequently it is even less efficient. This (2) remains no matter how fast we make the processor because the length of the computation becomes dominated by the time required to move data between (3) and memory. This is called the yon Neumann (4) . The bigger we build the machines, the worse it gets. The way to solve the problem is to diverse from the traditional architectures and to design special ones for Al applications. In the research of future Al architectures, we can take advantages of many (5) or currently emerging concepts. in computer architecture, such as dataflow computation, stack machines, tagging, pipelining, systolic array, multiprocessing, distributed processing, database machines, and inference machines.
