5.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 success of mankind.
Since 1960a new kind of tool has appeared.This is the silicon chip (硅芯片).It is smaller than a finger nail,but it can store lots 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.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?
64.From paragraph 1,we can knowC.
A.why early human beings cut skin from dead animals
B.how early human beings discovered the tools
C.what early human beings used the tools for
D.what food early human beings stored
65.The stone chip is thought to be the most important tool because itA.
A.was very important to the development of mankind
B.led to the invention of machines in the early time
C.developed cooking abilities of mankind
D.was one of the first tools of mankind
66.The silicon chip is mentioned in the passage toD.
A.show the changes of tools
B.introduce a new kind of tool
C.give an example of using tools
D.compare the effects of two kinds of tools
67.At the end of the passage the author seems to suggest that life in future isC.
A.out of order
B.less colorful
C.hard to predict
D.full of meanings.
分析 在本文中作者讲述了工具对人类社会发展的重要作用.首先锋利的石头片帮助人类度过了早期的艰苦岁月,然后电子芯片的发明给人类生活带来巨大的变化.科技的强大和发展的迅速使人们很难预测未来是什么样子的.
解答 64.C.细节理解题.根据第一段People used them for cutting meat and skin from dead animals,and also for making other tools out of wood可知从本段中我们可以知道早期的人类使用工具的目的,故选C.
65.A.细节理解题.根据文章第二段尾句"Some scientists say that it was the key to the success of mankind"可知"stone chip"对于人类的发展起到了非常重要的作用,故选A.
66.D.推理判断题.根据最后一段:Human beings used stone chips for more than two million years,but human life changed very little in that time.可知文章提到硅芯片是为了比较两种工具的作用;故选D.
67.C.推理判断题.文章最后一段中作者说人类在过去的几百万年时间里一直使用"stone chip",人类社会发生的变化很校而我们使用"silicon chips"才不过几年,生活却发生了巨大的变化.于是作者发出了疑问:"二十年后的生活会是什么样子的呢?","二百万年后的世界又会是什么样子呢?",表明将来的生活无法预料,故选C.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
