1. Read the text and do exercises after the text.
Pressing economic and social problems have plagued the world´s developing nations in the decades following World War II. The demand for natural resources, the creation of jobs, and the need for more open land to settle growing populations have led many nations to introduce deforestation pro- grams.
Although a useful short-term solution to economic problems, deforestation has disastrous consequences. Deforestation can decrease soil quality and create erosion problems, reducing rich forests to wastelands. The destruction of the tropical rain forests in Brazil threatens to alter the world´s climate and contribute to the greenhouse effect.
Deforestation recently led to a major disaster in Thailand. The Thai government´s 30-year policy of encouraging logging resulted in the loss of fully half the nation´s forests. A violent rainstorm that hit one of the deforested regions in November 1988 created flash floods on the bare, muddy hillsides. These floods killed 400 people and left thousands more injured and homeless.
If the forests had remained to absorb the downpour, floods would not have threatened the valley´s residents. By ignoring the consequences of their actions, Thai officials and loggers not only destroyed a vital resource but also created a disaster. Experts say the destructive floods have set the region´s economy back 20 years.

5. Edison considered that inspiration is more important than perspiration.

Edison is known as one of the greatest inventors of his time. He invented so much that it is difficult to say which of his achievements is the greatest. He was an experimenter and a practical man more than a theoretician.
Edison did not have any education. He went to school for only three months. Then he left because the teacher considered him a dull boy. His mother became his teacher. The boy loved books and his mother said that he had a wonderful memory. When he first visited a public library and saw a lot of shelves with books he decided that he would read all of them and then he would know everything in the world. He measured the shelf and decided to read a foot of books every week.
In 1868 Edison built his first patented invention – an electromagnetic device.
It is said that he planned to ask three thousand dollars for his invention, though he secretly decided he would sell it for two thousand if necessary He was invited to a meeting of businessmen who were interested in buying his invention, but when he was asked to name a price he was very nervous and quite unable to speak.
«It is no use asking us a big price», said one of the businessmen, «we’ve already decided how much we will pay. Forty thousand dollars is our limit».

Satellites are an important part of our ordinary lives. For example, the in- formation for weather forecast is sent by satellites. Some satellites have cam- eras which take photos of the Earth to show how clouds are moving. Satellites are also used to connect our international phone calls.
Television satellites
We use satellites to send television pictures from one part of the world to another. They are usually 35,880 kilometers above the equator. Sometimes we can see a satellite in the sky and it seems to stay in the same place. This is because it is moving around the world at 11,000 kilometers per hour – exactly the same speed that the earth rotates. A satellite must orbit the Earth with its antennae facing the Earth. Sometimes, it moves away from its orbit, so there are little rockets on it which are used to put the satellite back in the right position. This usually happens about every five or six days. Computer connections of the World Wide Web ad Internet also us satellites. Many of our programs come to us through satellites. Airplane pilots also sometimes use a satellite to help them find their exact location.
The Earth’s biggest dustbin?
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth. A satellite usually works for 10–12 years. Satellites which are broken are sometimes
