Step1: Warming up
Look at the following five photos and talk about their uses. An abacus is an old calculating machine which can solve a large number of mathematical problems. A calculator is a new calculating machine which can be used to solve a large number of mathematical problems A huge computer is built to solve some mathematical problems.A PC is a personal computer which can solve all kinds of problems and is used widely now.A notebook computer is a kind of useful computer which can be taken conveniently like a notebook. Now, let’s discuss what they have in common in small groups. Remember to use some of the following express-ions in your discussion.
I think that…
In my opinion…
I believe that…
What’s your reason?
Why do you think so? These machines can all calculate something. What’s more, from the abacus to the notebook computer, there was a long way. But now computers have already changed our lives greatly. They can be put into robots and make them useful and interesting. Step 2: Now let’s look at some photos of robots and talk about them.
What is a robot?
A robot is a program that runs automatically without human intervention. Typically, a robot is endowed with some artificial intelligence so that it can react to different situations it may encounter.
What is an industrial robot?
It is a tool that is used in the manufac-turing environment to increase productivity. Robots are used to do routine and tedious assembly line jobs, or hazardous jobs to the human in a variety of manufacturing tasks, such as welding, assembly and spray painting, and replacing the nuclear fuel rods in nuclear power plants etc.Step 3
Explain how the computer technology has been developing and complete the flow chart below. Then give a brief oral presentation on the development of computer technology with the help of the chart. When you’re preparing it, you can refer to the reading passage on Page 18 of the Student’s Book. Your oral presentation will be less than three minutes.Calculating machineAnalytical machineUniversal machineArtificial intelligencePC (desktop /notebook)Internet?HOMEWORK1 FIND MORE MATERIALS ON ROBOTS THROUGH THE INTERNET
