Sir Isaac Newton is an English scientist and mathematician. He was born in 1642, on the 25th of December in the little village of Woolsthorpe in England. His father was a wealthy farmer but he had died before Isaac was born.

Newton published his discoveries in two books which contain his three laws of motion and the universal gravitation law. The scientist used these laws to predict the motion of the planets around the Sun, the stars and comets motion. Isaac Newton studied optics and developed the theory of colour: he discovered that a prism could decompose white light into a multicoloured spectrum. He was also the constructor of the first practical reflecting telescope in the world. As for mathematics he and Leibniz developed the fundamental theorem of infinitesimal calculus.

I suppose all schoolchildren like holidays. Some of them are couch potatoes. They prefer watching TV, playing computer games and doing nothing. Others are very active, hard-working and sociable. They enjoy learning new things, reading new books, making new friends.As for me, I am very active and adventurous. I want to see the world and know everything. That is why I learn English and every holidays I try to go to a language camp where I can have a rest, improve my speaking English and have fun.Last winter holidays I spent in Luga in the camp. It is located in a beautiful place not far from the lake. Itis surrounded by tall pine-trees. When I came there I was impressed by nature. The trees, the ground, everything were covered with snow.There were about 70 boys and girls in the camp. We lived in comfortable double rooms.Every day we woke up early, rode horses, attended English classes, a theatrical circle and a dancing club. I liked English classes most of all. Our teachers were native speakers and we had a chance to talk to them in English. We practiced English through different situations, games and songs. It helped me to enrich my vocabulary and feel more confident in speaking English.
