1.Read and translate the text. Technology
The first computers were very big and slow. In 1943 Britain had a computer called “Colossus”. It worked with electronic tubes –like light bulbs. The first American computer in 1946 “ENIAC” had 18000 tubes. It weighed 30 tons and it filled a room of 160 meters. The ENIAC computer could do 5000 operations per second. Today the Cray supercomputers can do2 billion operations per second. Today you can buy a personal organizer with more power than ENIAC. It costs about $ 150 and you can put it in your pocket. As you know the most important part of the computer is the chip, it is also the brain of the computer. It has to be small, that’s why there are two reasons. The first one is convenience and the second one is the speed. In a small circuit the electronic signals arrive faster, simply because they travel a shorter distance. Electronic technology can change people’s lives. If the person is deaf , it is impossible to use the telephone. They need a videophone; it has a TV screen, so you can see other person. That means deaf people can use sign language on the phone!

4.Read the text: Computers: A Blessing or a Curse?
While reading focus on two points:
Is it really necessary to have a computer at home?
Is this article for or against computers?
Almost every home, office or school has a computer. Many people feel that these machines are now essential part of our lives, but how necessary are they really?
One of the main advantages is the time that can be saved by using a computer. This is especially beneficial in the workplace where employers can do their work far faster than in the past. In addition to this, computers can be educational and fun. From a very young age children can get basic computer skills through programs that allow them to learn, draw and play. In today's technological world this knowledge can only help them in the future.
The Internet has changed quite a lot of people's perspective of the world. While using the Internet you can get any information you need or you can have conversations with people from different countries.
However, there are various negative aspects in using computers. The computers can do many tasks more efficiently than humans. This has led to high unemployment in many countries. What is more computers can actually cause health problem. Endless hours in front of a screen can cause eye strain and headaches.
To sum up, it seems that computers are a useful addition to our fast - moving world of high technology. However, it must be remembered that they are here to serve us - not to replace us.
