2005年，我国小学生视力不良率为31.7%，初中生为58.1%，高中生和大学生的视力不良率分别高达76%和83%．也就是说我国的小学生每100人中，就有______视力不好．大学生中视力不好的人数占大学生总人数的______%．

答案

高中生和大学生的视力不良率分别高达76%和83%．也就是说我国的小学生每100人中，就有31.7视力不好，大学生中视力不好的人数占大学生总人数的83%；

故答案为：31.7人，83．

单项选择题

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.
