1.From space shuttles to eye-glasses, from air-conditioning to the Internet – inventions of the last centuries have completely transformed our lives and our world. The era of fascinating discoveries has changed the way we communicate, the way we spend our free time. The machine gun has made our world more dangerous, the parking meter – more expensive and refrigerators have changed our eating habits. We can’t imagine our life without electricity and domestic electric appliances today such as microwave ovens, toasters, washing-machines, dish-washers, vacuum cleaners, irons and many others. Our world is also impossible without modern means of transport: cars, trains, ships or airplanes.
2.I am really amazed by the greatest medical inventions of penicillin, anaesthetic, contact lenses, X-rays and many others. Penicillin is the name of an antibiotic that is used to kill dangerous bacteria in our bodies. This medicine was discovered in 1928 by Alexander Fleming. Many people worldwide stopped dying when their wounds had got infected. Of course, it is impossible to count how many lives have been saved by penicillin, but some estimate that it is about 200 million. As for X-rays, they were discovered by Wilhelm Rontgen in 1895 by accident. X-ray machines produced images of different parts in the human body. And since then they have been widely used for analyzing problems with bones, teeth and organs. Today they are also used at airports for luggage inspection.
3.I must say that some inventions are quite strange and funny. Among them are food fans (for making your hot food cool enough to eat), heated toilet seats or devices that translate dog barking. As for weapons, cigarettes and fast food, I believe they are the worst mankind inventions. Modern inventions should make our life easier and better, but they must not cause health problems or destroy our planet.
