    (1). Make a list of all the words and phrases you can find with which Gates refers to computer

    technology as if it were a road, journey, or adventure.

    (2). Do you think this comparison of computer technologies to a journey is an effective one? If

    so, explain how the image of travel fits well with the new technologies. If not, what would be a

    better comparison?

    D. Dictation

     The word robot first appeared in 1921, in a Czech play about rebellious machines that had some

    human characteristics, and is derived from the Czech word for "forced labor". It is mainly as

    helpers, though that robots have found their way from fiction into the real world. In particular,

    they are used to perform many tasks too dangerous, difficult or boring for humans. For example,

    robots have explored the wreck of the Titanic, and a robot even helps doctors to perform brain


    E. Group Activity

     What can the robot in the picture do/

     What would you like it to do?

    Step 2 Ask Ss to work in groups to program a robot, deciding what it can do and what it cannot do,

    how to operate it (whether it reacts to voice, light, touch, or anything else)

    Step 3 after each group presents their robot, have Ss choose the Best Robot of the Class.

    7. After-class Assignments

    Write a short passage to elaborate on (阐发) Gates’ metaphor that “computers are a revolution.”

    First, think about what ideas you associate with a revolution (for example, “war”, “violence,”

    complete change”) and then decide which of these ideas can be compared to computers. You may

    use a dictionary to get ideas about the different meanings “revolution” can have. (Or, if you do not

    think that “revolution” is a good metaphor for computers, you may compare computers to

    something else you have thought of.)

     Text B Smart Mashines: Our Tireless Helpers

    Language Points:

    1. a computer’s capabilities in relation to a human’s ------ the qualities and abilities which a

    computer has, in comparison with those of a human being

    2. they figured that… ------ they estimated or predicted that…

    3. stopped dead ------ stopped suddenly and completely

    4. more advanced descendants of Dante ------ robots more powerful than Dante that will be

    created in the coming years

    5. Can science and technology take us too far by programming intelligence into machines?

    ------ Is there a danger that artificial intelligence will lead to the development of machines

    that are so advanced that they are harmful, rather than beneficial, to humans?

    6. The prediction is for a good working relationship between human beings and their

    tireless helpers. ------ It seems most likely that people in the fuure will be able to depend on

    machines to do work for us, but there is no need to worry about being controlled by them.
