Read the text and choose the correct statement. A robot is a machine that does work for people. The word ‘robot’ appeared in the 1920s and it was first used in a science fiction story. In real life, the robot was invented later, in 1954. There are different kinds of robots which are used in different industries. Most of them are operated with the help of a computer program. Instead of humans, robots do hard and boring work in unpleasant or dangerous environments. They usually work faster and more accurately than people. They never get tired and do not make mistakes. Nowadays, robots are often used for domestic needs – to clean houses or to look after sick and elderly people. Scientists say that soon robots will become a normal part of our life, like mobiles and computers today.
