However, not everybody knows much about the life of this remarkable man, except perhaps that he was born in the market town of Stratford-upon-Avon and that he married a woman called Anne Hathaway. We know nothing of his school life. We do not know, for example, how long it lasted, but we presume（推测）that he attended the local grammar school, where the principal subject taught was Latin. Nothing certain is known of what he did between the time he left school and his departure（出发）for London. According to a local legend, he was beaten and even put in prison for stealing rabbits and deer from the estate of neighboring landowner, Sir Thomas Lucy. It is said that because of this he was forced to run away from his native place. A different legend says that he was apprenticed（做学徒）to a Stratford butcher, but did not like the life and for this reason decided to leave Stratford. Whatever caused him to leave the town of his birth, the world can be grateful that he did so. What is certain is that he set his foot on the road to fame when he arrived in London. It is said that at first he was without money or friends there, but that he earned a little by taking care of the horses of the gentleman who attended the plays at the theatre. They stopped and spoke to him. They found his conversations so brilliant（有才气的）that finally he was invited to join their company. 1．In the early life of Shakespeare, he_______.
