When my daughter Lee and his friends wanted to make planter boxes and sold them, I was glad they decided to earn money instead asking their parents for it, so I agreed to lend them hand. I gave them some carpentry (木工) lesson, and they all seemed capable (有能力) and carefully with my tools. Since they work behind the garage, a house is quieter than used to be. They are learning how to use money on a responsible (负责的) way, and I can tell that they feel quite be proud of themselves. | 1. ________ 2. ________ 3. ________ 4. ________ 5. ________ 6. ________ 7. ________ 8. ________ 9. ________ 10. ________ |
