Teaching Goals:

1. To know something about computers. 2. To learn and talk about computers.

Teaching Procedures: Step 1. Leading-in Purpose: To activate the Ss and arouse them to talk about the importance of computers in modern society. Ask Ss whether they have a computer or not and what they use it for. Let them talk as much as possible. Step 2. Warming Up

Purpose: To get Ss to think about the different ways computers can be made.

Step 3. Pre-reading Purpose: To activate Ss’ interest about computers. Step 4. Reading 1. Skimming Purpose: 1. To get a brief understanding of the text.

2. To train the students’ listening ability.

First, let Ss skim the text and then listen to the recording of the text. Pay attention to the pauses and pronunciation. 2. Scanning Purpose: To get Ss to have some details in the text.

Now we are to read the text again and underline all the expressions in the text. Write them down in your notebook. 3. Further Reading Purpose: To get Ss to get more details about the text.

Step 5. Retell Purpose: To have a deep understanding of the text. Ask Ss to use the chart above to retell the development of the computer. One possible version: I, a computer, was a calculating machine in 1642 in France. Then I was built as an Analytical Machine in 1822, which was a technological revolution. I became a “universal machine” in 1936 to solve any mathematical problem. I was not very big at first then I became huge, the size of a large room before I was made smaller and smaller.

Getting new transistors, later very small chips I changed my shape. I was connected with other computers and turned out to part of a network in the early 1960s. In 1970s I was brought into people’s homes, and came the Internet.
