Learn something about the

inventors and inventions to help the students know the importance of science . Teaching difficult points: 1.

How to get the students to master the usage of the useful words and phrases in the passage . 2.

How to improve the students’ reading ability . Emotional goal:

How to inspire Ss’ devotion to scientific inventions. Teaching aid:

a tape-recorder ,multi-media . Teaching procedure:

Step1. Lead-in

Ask students to look at the picture on the screen and ask : What is the man doing ?Then enjoy the pictures of computers. Ask: Do you know the following different kinds of computers?

Step 2. Pre-reading

Let students look at the pictures on the screen, brainstorm the usages of a computer..

The suggested answer:

We can use a computer

to search for information, to listen to music, to do shopping, to communicate with friends, watch movies, play computer games, etc. Step 3. Reading : Who Am I ?

This is a short history of the development of computers. It introduces a lot of new and technical words ,which are only used for computers. Fast reading

Task 2: Skim the incomplete article to get the main idea and think about the following question:

How did you find the main idea?

Show some important sentences of the paragraphs for the students to take a rapid look and guess the main idea of the reading passage. This article is about the development of computers Tell the students the function of a topic sentence and its location:

A topic sentence sets out the main idea of a paragraph; It is usually the first or last sentence of a paragraph. Show the following paragraphs for the students to read and tell the right order of the details. The right order of the details: C

I began as a calculating machine in France in 1642. Although I was young I could simplify difficult sums. I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator who used cards with holes, I could “think”

logically and produce an answer quicker than any person. At that time it was considered a technological revolution and the start of my “artificial intelligence”. In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a “universal machine”

to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower.

A

First it was stored in tubes, then on transistors and later on very small chips. As a result I totally changed my shape. As I have grown older I have also grown smaller. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! And my memory became so large that even I couldn’t believe it! But I was always so lonely

standing there by myself, until in the early 1960s they gave me a family connected by a network. I was able to share my knowledge with others through the World Wide Web.

B I have become very important in communication, finance and trade. I have also been put

into robots and used to make mobile phones as well as help with medical operations. I have even been put into space rockets and sent to explore the Moon and Mars Careful-reading: Play the tape of the reading Who Am I ? for the students to listen and read aloud, paying attention to the pronunciation and intonation of some words., find out the answer to the following question.

: How does the article develop?

It is developed by time

Ask the students to fill in the following blanks: 1642:_____________________________________ 1822: The analytical machine was made by Charles

Babbage. ____:_____________________________________ 1940s :___________________________________ _____:The first family of computers was connected

to each other. 1970s:______________________________________ Now :_______________________________________

Step4 .Summary Computers are becoming more and more popular.

, few can imagine what the

computers looked like. At the beginning, a computer was the

changed after they were

with new transistors. Later, computers were

by a network. With it people can
