人教版（2019）选修1《Unit 2 Looking into the Future》2021年同步练习卷（板块二）

Ⅰ.阅读理解

• 1．The human brain contains 10 thousand million cells（细胞）and each of these may have a thousand connections.Such great numbers used to discourage us and cause us to stop thinking about the possibility of making a machine with humanlike ability，but now that we have grown used to moving forward at such a speed，we can be less sure.Quite soon，in only 10 or 20 years，perhaps，we will be able to build a machine as complex（复杂的） as the human brain，and if we can，we will.It may then take us a long time to make it as intelligent as the human brain by properly programming it.
     I think it is certain that in decades，not centuries，machines of silicon（硅）will arise to compete with their human ancestors.In a real sense they will be able to reproduce themselves.Silicon will have ended carbon's long control.And we will no longer be able to consider ourselves to be the finest intelligence in the world.
     As the intelligence of robots increases and their cost goes down，we may achieve a lot with their help，first on the earth through their ability to complete any kind of work in harmful environments.In the end，deserts（沙漠）may turn into gardens.Further ahead，by a combination of the great wealth this new age will bring and the technology it will provide，the creation of a huge，man-made world in space，home to thousands or millions of people，will be within our power.
