Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat-eating animals, such as lions and tigers. Tools helped people to get food more easily.
Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to the success of mankind.
Since 1960 a new kind of tool has appeared. This is the silicon chip --a little chip of silicon crystal. It is smaller than a finger-nail, but it can store more than a million" bits" of information. It is an electronic brain.
Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways.
In the future we will not need to work with tools in the old way. Machines will do everything for us. They will even talk and play games with us. People will have plenty of spare time. But what will they do with it?
Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years from now? [br] Which of the following is not true about the silicon chip?
选项
A、It has appeared since 1960.
B、It is an electronic brain and can store a lot of information.
C、It is a chip of silicon crystal and is very small.
D、It becomes cleverer and more expensive every year.
答案
D
解析
细节理解题。根据文章第四段,芯片变得越来智能,体积越来越小,却越来越便宜。因此,D项的阐述不正确。
