网考网参考答案：B
网考网解析：
[解析] 文章第三段第一句话“There fore，if the computer is to compete at championship levels，it must be programmed to function with less than complete data．”这句话的意思是说计算机如果要达到冠军水平，它运行起来也不会有完全的数据。因此，选项A)是错误的，因为它强调计算机要思考的话，需要足够多的资料。文章中第三段的第二句话“It must be able to learn from experience，to modify its own program，to deal with a relatively unstructured situation—in a word，to‘think’for itself.”阐述了计算机的“思考”其实就是从经验当中得到学习，修正自己的程序，以及处理相对不规则情况的能力。因此B) learn from the experience and reason，从经验中学习并且有推理能力符合上述有关思考的定义。而C)中则因为structure 这个单词，就可以判定不是正确答案。在第二段中第一第二句话“All a programmer has to do is give the computer a program evaluating the consequences of every possible response to every possible move，and the computer will win every time. In theory this is a sensible approach； in practice it is impossible”说明了要预测棋子的每一步移动在现实生活中是不可能的，因而选D)是错误的，所以这一题选B)。 查看试题解析出处>>
