прочитать ещё раз текст о Leonardo da Vinci, составить к нему 7 специальных вопросов (wh-questions ТЕКСТ;
Leonardo da Vinci was born on April 15th, 1452, at Vinci, a small town near Florence in Italy. The sculptor and painter Verrocchio was his teacher in art. Most of his life Leonardo worked in Italy for rich noblemen, but he spent his last years in France. King Francis I of France appointed Leonardo to the position of ‘First painter, architect and mechanic of the King’ and gave Leonardo a beautiful and comfortable house near the King’s own residence where he often visited Leonardo for conversation. The King paid Leonardo well and allowed him to pursue his own interests in engineering and architecture. Leonardo died in France at the age of 67, on 2nd May 1519.Leonardo da Vinci was a genius. He was good at many things, but many people think that Leonardo was one of the greatest painters of all time. Two of his pictures, the ‘Mona Lisa’ and ‘The Last Supper’ are among the best-known paintings in the world. He did lots of drawings. The best-known drawing is the ‘Vitruvian Man’.Leonardo was also a sculptor, architect, musician, engineer, inventor, anatomist and botanist. Leonardo never went to school or university; he was educated in his father’s house receiving the usual elementary education of reading, writing and arithmetic. But his education never ended — he was interested in the world around him. His desire for knowledge was very strong. He was interested in exploring human and natural sciences: civil engineering, chemistry, geology, geometry, hydrodynamics, mathematics, mechanical engineering, optics, physics, pyrotechnics and zoology. He was also an inventor. He made a contribution to everything known today. Hecame up with the idea of a helicopter, a tank and solar power. He constructed a calculator. For much of his life Leonardo was fascinated by the phenomenon of flight. He made many studies of the flight of birds, as well as plans for several flying machines. These plans included a helicopter and a light hang glider.He drew the things he saw and made notes about the discoveries he made in his notebooks. Leonardo’s notebooks are hard to read because he wrote backwards in ‘mirror writing’. The notebooks were not published in Leonardo’s lifetime. Many of his notebooks are now in museums or libraries such as Windsor Castle, the Louvre and the British Library.
