根据短文内容，回答下列问题。
Many years ago, there was a family named Franklin. They lived in Boston. There were five girls and
six boys in the family. On a January day in 1706 another baby was born. The boy's mother and her
husband gave the boy a name-Benjamin. Benjamin was the cleverest of all the children. He could read
when he was five and write when he was seven. The next year his parents sent him to school.
In school Benjamin was good at reading and writing, but not good at math. He read all of his father's
books. And when he had money, he always went to buy books. He liked books. They told him how to
do something. The boy liked to use his head and tried to find ways to help people enjoy life more. For
example, he tried to know if there was some way to swim farther, maybe with something on his hands or
feet. Slowly a picture of swimming shoes, or paddles, grew in his mind. The paddles must be neither too
big nor too small. And they must be neither too heavy nor light. At last he invented the paddle for
swimming.
