It was a sunny day last Sunday.Peter was so bored so he read some books.He read a book called'Learning swimming is easy '.After reading the book,he bought a pair of swimming trunks immediately and went to the public swimming pool.There he jumped into the public swimming pool and used the skills which the book taught him.But he could not swim,so he cried for help.Soon a lifeguard jumped into the water and took Peter out of the water.Peter was sent to the hospital immediately.After he was sent out from hospital,he joined a swimming class.He knew that reading books cannot teach him how to swim.He wanted to be a lifeguard in the future to help more people.
