One day, I fished with my grandfather. When we sat by the river, our bobbers（浮漂）floated（浮动）together. He told me to be patient. We were lucky to enjoy the warmth of the sun. I was with my grandfather happily. I wanted to be like him.
My grandfather was an amazing man. He taught me many things- the way to fish, the value of good friends, the respect for the old and the importance of working hard. The list was long. My grandfather didn't always teach me or tell me directly.
The family tree is a learning tree.
Over time, the branches（树枝） above grow large, join with other families, and protect the older branches below.
| A．Instead. I learned them from my mother. |
| B．He was well liked by everyone. |
| C．Gradually, the old branches grow weak, die and fall away. |
| D．Then the things my grandfather taught my mother would be passed on to me. |
| E．The larger, older branches support and guide the smaller, younger ones. |
