Book2 Unit3 Computers
----Reading
Teaching aims:
1. Target language
a. Important words and expressions：calculator, notebook, common, calculate, analytical, technological, revolution, universal, mathematical, simple, artificial intelligence, any way, totally, network, truly
b. Sentences
1) My real father was Alan Turing, who in 1936 wrote a book to describe how computers could be made to work, and built a "universal machine" to solve any mathematical problem. P18
2) As the years have gone by, I have been made small er and smaller. P18
3) I became small and thin but I got cleverer and cleverer, quicker and quicker. P18
4) And my memory became so large that I couldn't believe it! P18
2. Ability goals
Enable the students to grasp the progress of computers.
3. Learning ability goals
Enable the students to state the progress in chronology order.
Teaching important points
Try to finish the exercises of Comprehending.
Teaching difficult points
Enable the students to learn how to grasp the structure of the text.
Teaching procedures:
Step I Warming up
T: Look at the pictures please.What are they
S: They are …
T: If I were a maths teacher, which would help me most Why
S: I think …because…
I believe that…
In my opinion, …
…
T: Then how do you use computers and the Internet
S: I often use a computer to…, I sometimes use it to…, and I never use it to…
T: Computers have great power. They make our lives more colorful and more convenient(方便的 ) . But don’t just use computers for fun. Don’t spend too much time in playing computer games or chatting(聊天) online. We should learn more computer skills(技能)which are very useful in our future work.

3. Listening
True or False
(1) In 1642 I began as a calculating machine and could solve any mathematical problem.
(2) My real father was Charles Babbage, who wrote a book and built me in 1936.
(3) After I got my new transistors and small chips, I totally changed my shape.
(4) Since the 1970s I have been used in offices and homes.
(5) I am now truly filled with happiness that I can replace the human race.
4. Summary
I began as a machine in 1642 in france. After two hundred years, I was built as an machine by Charles Babbage. In 1936 my real father, Alan Turing, wrote a book about how to make me work as a “ machine” to any difficult mathematical problem. As time went by, I was made smaller. Since the 1970s I have been used in offices and homes. In early 1960s, I was given a family connected by a . So I was able to share my knowledge with others through the . I have become very important in communications, and trade. I’m now truly filled with that I am a devoted friend and helper of the !
Step Ⅲ Interview
Work in groups of four.
Choose one student as Mr./Miss Computer, and the other students as reporters.
The reporters may ask the following questions:
(1) Where were you in 1642
(2) What happened to you in 1822
(3) What were you called in 1936
(4) What did you get in 1960s
(5) What happened to you in 1970s
Some other questions will be better.
Sample interview:
R1=Reporter1; R2=Reporter2; …;Mr./puter
R1: Hello, Mr./puter. We come to your time
to know more aboutyou. Can we ask you some questions
C: Of course you can. What would you like to know
R1:Where were you in 1642
C: …
R2: What happened to you in 1822
C: …
R3: What happened to you in 1970s
C: …
RS: Thank you for your time. Goodbye.
StepⅣ Homework:
1. Read the text again and find out the difficult language points.
