A computer is a machine designed to perform work mathematically and to store and select information that has been fed into it. It is run by either mechanical or electronic means. These machines can do a great deal of complicated work in a very short time. A large computer, for example, can add or subtract nine thousand times a second, multiply a thousand times a second, or divide five hundred times a second. Its percentage of error is about one in a billion digits. It has been estimated that human beings making calculations average about one mistake per two hundred digits.
The heart of an electronic computer lies in its vacuum tubes, or transistors. Its electronic circuits work a thousand times faster than the nerve cells in the human brain. A problem that might take a human being two years to solve can be solved by a computer in one minute, but in order to work properly, a computer must be given instructions—it must be programmed.
Computers can be designed for many specialized purposes, they can be used to prepare payrolls , guide airplane flights, direct traffic, even to play chess. Computers play an essential role in modern automation in many plants and factories throughout the world.
This passage indicates that human beings differ from computers in that human beings______.
选项
A、do not have to be programed
B、make fewer errors
C、understand their instructions
D、work more quickly
答案
A
解析
此题是一道推断题。我们首先应结合文章的主题找出与问题相关的信息,然后进行深入细致的推断。文中第二段最后一句说:“一个也许需要花费一个人两年时间才能解决的问题,而靠计算机只要一分钟就可以解答出来。不过为了能正确地运行,计算机必须接受指令,也就是说必须给计算机编程序。”此句“but”一词后说必须给计算机编制程序,可以看出人正好与计算机相反,由此可推测出选项A正确。
