    An old carpenter(工匠)was ready to retire(退休).His boss was 1 to see the good worker leave. He asked the carpenter if he could build just one more 2 . The carpenter said yes, but his mind was not on his work any more. He used poor materials and 3worked on the house. When the carpenter finished his work, the boss  4 the front-door key to him and said, "This is your house. It's a 5 for you."

    What a surprise! If he had known he was 6 his own house, he would have done it differently. Now he had to live in the house he poorly built.

    So it is with us. Sometimes we build our 7 carelessly. At important points we do not try our best. Then with a shame we look at the things we did. We find that we are living in the house we have poorly built 8we don't have a chance(机会)to make it all over again.

    Think of  9as the carpenter. Think about your life. Build it carefully and wisely. It is the only life you will ever build because life is a do-it-yourself project.

    Your life today is the 10 of  your attitudes(态度)and choices(选择)you made in the past. Your life tomorrow will be that of your attitude and choices you make today.

    John is thirteen now. He began to study in a middle school two years ago. His home is in a small village and it's nearly five kilometers from the school. He has to get up early in the morning.

    After a quick breakfast he has to run to school and get there on time. His father hopes to borrow some money to buy a bike for him, but he knows his mother is always ill and his father spends much money on medicine. He doesn't agree with his father and keeps running there every day. Now he's very strong. He is never late for class and his teachers often praise him.

    Last week there was a sports meeting in his school. John ran faster than any other boy and won the boy's 800 meters, 1, 500 meters and 3, 000 meters. The whole school knew him. He was very happy. He told his grandma about the good news as soon as he got home.

    "I broke two school records（记录）today, Granny," called out the boy.

    To his surprise, the old woman wasn't happy. She thought for a while and said, "I'm sorry to hear that. We have no money to pay for them, you know!"

    Terry Fox was only seventeen when he got a cancer (癌症). He must have felt hopeless when the doctor said his right leg would have to be cut off 6 inches above the knee.

    But to everyone's surprise, Terry Fox made up his mind to become a long-distance runner and do something about the cancer. What a dream!

    Although it seemed impossible, Terry decided to run across the whole country. He hoped to raise one million dollars for cancer research. Few believed he would make it. Anyway, on April 12, 1980, Terry Fox began his Marathon of Hope. For the first days of his marathon, Terry Fox was alone. He started running at 4:30 am. Day by day, people began to realize that something big was happening on the lonely road. As people saw Terry, they stopped and donated (捐赠) money for cancer research.

    However, his health took a rapid turn for the worse several months later. He had to give up his marathon on September 1, 1980. Terry died three months later, at the age of 22. In his short life, he raised $24 million for cancer research—one dollar for each person in his motherland.

    Since his death, the yearly Terry Fox Run, first held in 1981, has grown to be the world's largest one-day fundraiser (筹资活动) for cancer research.

    I had spent an hour in the bank with my dad to transfer some money (转账). I ask him, "Dad, why not use online banking?" "Why would I do that?" He replied.

    "Well, then you won't have to spend an hour here to transfer your money. You can also do your shopping online. Everything will be easier!" I said in excitement. He asked, "If I do that, I won't have to go out of the house?"

    "Yes!" I said. I told him how groceries (杂货) can be delivered to our doors now. And we can buy everything we need by just staying at home.

    However, he said, "Since I walked into this bank today, I have met four of my friends. I have much free time, so I like to come to the bank and meet different people. Two years ago, when I was in hospital, the store owner from whom I bought fruit came to see me. And when your mom fell down a few days ago, the bank manager saw her and helped her get to the hospital."

    He went on, "why would I want to look at my computer all the time? I like to know the person around me. Does Amazon send bonds (情感纽带) and relationships, too?"

    I didn't know what to say after hearing his words. My dad was right, of course. It's better for us to spend time with real people than computers.
