John was sent to boarding school at the age of ten.

Before he left, he was given some spending money (или some spending money was given to him) and he was told by his father to obey his teachers.

He had never been sent away on his own before, so he felt a bit nervous on the train, although he knew that he would be picked up by somebody at the station.

When he arrived at the school he was shown to his room (или his room was shown to him) and he realised that it would have to be shared with twenty other boys!

But after he had been taken round the school by some older boys and he had been invited to play football, he knew he would be happy there.
