Since 1989, Dave Thomas, who died at the age of 69, was one of the most recognizable faces on TV. He appeared in more than 800 commercials for the hamburger chain named for his daughter. “As long as it works”, he said in 1991, “I'll continue to do those commercials.”

    Even though he was successful, Thomas remained troubled by his childhood. “He still won't let anyone see his feet, which are out of shape because he never had proper fitting shoes,” Wendy said in 1993. Born to a single mother, he was adopted as a baby by Rex and Auleva Thomas of Kalamazoo in Michigan. After Auleva died when he was 5, Thomas spent years on the road as Rex traveled around seeking construction work. “He fed me,” Thomas said, “and if I got out of line, he'd beat me.”

    Moving out on his own at 15, Thomas worked, first as a waiter, in many restaurants. But he had something much better in mind. “I thought if I owned a restaurant,” he said, “I could eat for free.” A 1956 meeting with Harland Sanders led Thomas to a career as the manager of a Kentucky Chicken restaurant that made him a millionaire in 1968.

    In 1969, after breaking with Sanders, Thomas started the first Wendy's Old Fashioned Hamburgers, in Columbus, Ohio, which set itself apart by serving made-to-order burgers. With 6,000 restaurants worldwide, the chain now makes $ 6 billion a year in sales. Although troubled by his own experience with adoption, Thomas, married since 1954 to Lorraine, 66, and with four grown kids besides Wendy, felt it could offer a future for other children. He started the Dave Thomas Foundation for Adoption in 1992.

    In 1993, Thomas, who had left school at 15, graduated from Coconut Creek High School in Florida. He even took Lorraine to the graduation dance party. The kids voted him Most Likely to Succeed.

    “The Dave you saw on TV was the real Dave,” says friend Pat Williams. “He wasn't a great actor or a great speaker .He was just Joe Everybody.”

    We may not be aware of it, but ordinary family homes in the U.S. and the rest of the world are not energy-efficient.

    Most of their energy goes to heating and cooling, and a lot of it is wasted, as warm air and cool air escape through fireplace chimneys and thin or poorly fitting windows and doors. A passive house loses almost none."Imagine a thermos(保温瓶),"said housing developer Brendan O'Neill."You have insulation(隔绝) everywhere, and it's basically completely sealed. And so the idea is to build a house like a thermos. So the windows are sealed. There's insulation completely surrounding the building. We make it as sealed as possible."

    A 147-square-meter passive house, presented by O'Neill Development Corp. as a demonstration unit just outside Washington, was brought to the site in two boxes. "Once it's set and put together, it takes about four weeks to complete the outside construction, to put down carpets," O'Neill said. "If everything is set in place, you put a house like this together in about four months.”The total cost of building it was $325,000, or about 17 percent more than constructing an ordinary house. But its utility(公用事业) bill is only around $20 monthly, or one-tenth the amount for the average house of the same size.

    While passive houses have been around for a long time, the idea has never taken root in the U.S. There was no driving force to push it.

    However, David Peabody, an architect who designs passive houses said, "I think climate change is now becoming a larger issue. And I think building standards are catching on to that. So people are becoming more aware of energy."Peabody said the cost of building passive houses could come down."What really makes sense for truly affordable housing," he said, "is to build multi-storey buildings."

    In China, many people are leaving the countryside to find jobs in the cities, because the countryside is much poorer than the city, and often there isn't much work there. Services such as hospital and transport are usually much better in the city than in the countryside. They hope that their lives will improve when they move to the city.

    But in the big cities of Europe like London or Pads, people are moving out of the city. These rich families want to live a quieter life. They are tired of the noise and the dirt of the city, and they are tired of the crowded streets, crowded trains and buses. They don't want to live in the cities any more. They want a house with a garden in the countryside, and breathe the fresh air there.

    So they move out of the cities. Some don't go very far, just a little way out of the city, to the towns near the cities, other people move to the real countryside with sheep, cows and green fields. There, they start new lives and try to make new friends.

    Not all those who move from the city to the countryside are happy. After two or three years, many people who have done this feel that it was a big mistake. They don't make so much money and there isn't much work to do. People in the countryside are very different and aren't always very friendly.

    As a result, quite a lot of people who have moved to the countryside move back to the city. "

    It's wonderful to see crowds in the streets and cinema lights," they say.

    One morning more than thirty years ago, I entered the Track Kitchen, a restaurant where everyone from the humblest(卑微的) to the most powerful came for breakfast. I noticed an empty chair next to an elderly, unshaven man, who looked somewhat disheveled. He was wearing a worn-out hat and was alone. I asked if I might join him. He agreed quietly and I sat down to have my breakfast.

    We cautiously began a conversation and spoke about a wide range of things. We never introduced ourselves. I was concerned that he might have no money and not be able to afford something to eat. So as I rose to go back to the counter and buy a second cup of coffee, I asked,

    "May I get you something?"

    "A coffee would be nice."

    Then I bought him a cup of coffee. We talked more, and he accepted another cup of coffee, Finally, I rose to leave, wished him well, and headed for the exit. At the door I met one of my friends. He asked,

    "How did you get to know Mr. Galbreath?"

    "Who?"

    "The man you were sitting with. He is chairman of the Board of Churchill Downs."

    I could hardly believe it. I was buying, offering a free breakfast, and feeling pity for one of the world's richest and most powerful men!

    My few minutes with Mr. Galbreath changed my life. Now I try to treat everyone with respect, no matter who I think they are, and to meet another human being with kindness and sincerity.

    The world is too big to take in all at once. To make sense and beauty of it, you have to look at a small part at a time.

    In using a camera, you choose a small part through he view finder. You move the camera, "framing" pictures until you see one that pleases you. Then-click! If you make a good choice, your picture will please others, as well as yourself.

    "Wherever you are," says photographer Ernst Haas, "you are surrounded by pictures. The trick is to recognize them." His photograph of a twist of barbed wire shows what he means.

    Mr. Haas tells us of ways to practice seeing. Make a simple frame of black cardboard. Take it out of the doors and look through it at everyday things, large or small, far away or near.

    At first you may see nothing to interest you. But soon pictures seem to leap (跳) at you through the frame. Oil floating on water makes a picture in rainbow colors. Three people on the steps of an old house form a picture that seems to tell a story.

    Did you notice such things before you used the frame? Perhaps not. But, with practice, you soon do not need its help. You see things as artists do. Everywhere, shapes and colors catch your eye. Your mind takes "snapshots (快照)" of their patterns. Then, if you wish, you can share what you see by taking a photograph or by making a drawing or a painting.

    Sometimes it's fun to "see small". Did you ever notice the design of the seeds in sliced bananas? Have you looked deep inside a lily? Or seen the starburst in the center of a wet ice cube?

    Do you see colors as they really are? When you paint tree trunks, you would make them brown or black. But tree trunks are really gray, purple, yellow-green—almost any color except brown or black!

    Do you notice detail? Doing so can be in many ways. Remembering what you see is often useful, too. Practice can help you.

    A trick for helping you to remember detail is the double take. Look—don't look—then look again.
