I was born in England.Wher I was only fourteen years old my father sent me to Cambridge to study medicine .I studied there for three years . When I left college I went on with my studies and became a doctor . I always wanted to travel . I became a doctor on a ship sailing both to the east and to the west indies.On May 4, 1699, I siled from Bristol for the south seas as a doctor of a ship named the Antelope. At first, everything went well but then there was a great storm. The ship came very close to the rocks and crashed into them . Some of the sailors and Igot a boat into the water. It was a small boat. When a big wave hit it, we all fell into the sea. I was swimming for a very long time and got very tired. I felt that I could not swim any longer. But the shore was not far away and soon my feet touched the ground. I walked oul of the sea to a beach - there wery no houses , there were no people. I was so tired that I lay down and fell asleep. можете сделать краткий пересказ этого текста дам 50 баллов
