Memory, they say, is a matter of practice and exercise. If you have the wish and really made a conscious（自觉的）effort, then you can quite easily improve your ability to remember things. But even if you are successful, there are times when your memory seems to play tricks on you.

    Sometimes you remember things that really did not happen. One morning last week, for example, I got up and found that I had left the front door unlocked all night, yet I clearly remember locking it carefully the night before.

    Memory “trick” work the other way as well. Once in a while you remember not doing something, and then find out that you did. One day last month, for example, I was sitting in a barber（理发师）shop waiting for my turn to get a haircut, and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office.

    We always seem to find something funny and amusing（有趣的）in incidents caused by people's forgetfulness or absent-mindedness. Stories about absent-minded professors have been told for years, and we never got tired of hearing new ones. Unfortunately, however, absent-mindedness is not always funny. There are times when “trick” of our memory can cause us great trouble.

    Edward Hibberd Johnson was an American inventor. He lived in New York City in the 1800s. In 1882, Johnson had an idea. It would change the look of Christmas forever.

    Johnson worked as a boss at a technology company. In 1871, he hired a young man to work for him. The man's name was Thomas Edison. Edison was a great worker. He came up with many new ideas. Later, Edison left to start his own company. Johnson followed him. Johnson started turning Edison's ideas into money. In 1880, Edison invented the light bulb. No one knew how much it was worth. At the time, most homes did not have the electricity to power it. However, Johnson helped start a company to sell the bulbs.

    Before long, Mr. Johnson had a bright idea. Christmas trees were very popular. They were so beautiful because of their candles. Flickering (闪烁的) flames were perfect for Christmas. But they were also dangerous. They could easily start a fire.

    Mr. Johnson thought of a way to fix this. He set up a Christmas tree by one of his windows. Then he took 80 colored light bulbs and hung them around it. The lights were red, white and blue. People on the street stopped to look. They admired the shining Christmas tree. It was so popular that Johnson made it a tradition. Each year he added more lights. In 1884, there were 120 light bulbs on his tree. The lights were not cheap. In 1900, a string of 16 bulbs cost $12. That was a lot of money back then, because people made less. In today's money, that is about $350. But over time, they started to cost less. By the 1930s, colored light bulbs were everywhere.

    Today millions of light sets are sold in America each year. They light 80 million homes. Some of them are now used for other holidays too. They are used on Halloween and Valentine's Day. But it all started with Johnson's Christmas tree.

    Generally speaking, government regulations normally ban anything from smoking in public places to parking in certain zones. But officials in the Brazilian town of Biritiba Mirim, 70km (45miles) east of Sao Paulo, have gone far beyond that. They plan to prohibit residents from dying early because the local cemetery(墓地) has reached full capacity.

    There's no more room to bury the dead, they can't be cremated(火化) and laws forbid a new cemetery. So the mayor has proposed a strange solution: outlaw death. Mayor Roberto Pereira says the bill is meant as a protest against federal regulations that prohibit new or expanded cemeteries in preservation areas. "They have not taken local demands into consideration", he claims.

    A 2003 decree(法令) by Brazil's National Environment Council forbids burial grounds in protected areas. Mr. Pereira wants to build a new cemetery, but the project has been stopped because 98% of Biritiba Mirim is considered as a preservation area.

    Biritiba Mirim, a town of 28,000 inhabitants, not only wants to prohibit residents from passing away. The bill also calls on people to take care of their health in order to avoid death. "I haven't got a job, nor am I healthy. And now they say I can't die. That's ridiculous," Amarido do Prado, an unemployed resident said.

    The city council is expected to vote on the regulation next week. "Of course the bill is laughable, illegal, and will never be approved," said Gilson Soares de Campos, an assistant of the mayor. "But can you think of a better resolution to persuade the government to change the environmental decree that is prohibiting us from building a new cemetery?" The bill states that "offenders will be held responsible for their acts." However, it does not say what the punishment will be.

    Morning Environmental Education Program

    A fun environmental based activity program for kids will be held in the mornings at Camp Hawk. Curriculum(课程) is designed to be interactive(互动的). Fees are $60 and includes lunch.

    Camp Hawk is open to children of abilities; however, daily participation(参加) requires that a child be able to stay with the group while outside on adventures, as well as to listen to and follow directions from the counselors(辅导员).

    Topics Include:

    Tuesday: Kids will build a space station with legos(儿童积木), and build their solar system with bottle caps.

    Wednesday: Kids will learn about the importance of the mangroves(红树) to the Florida Keys and other areas of the world. They'll take a field trip to explore life in the mangroves, and make their own mangrove poem.

    Thursday: Campers will learn about the bottle nosed dolphin and the types of sharks that live in the keys. This session will also take them out of the classroom to the Dolphin Connection observation area.

    Friday: This day is all about reptiles(爬行动物). Kids will learn about "The mixed up Chameleon" activities and art project, Reptile "hunt" fieldtrip, and making lizard bracelets.

    Saturday: Campers will learn about all of the creatures of Florida by taking a fieldtrip to observe dolphins, fish, birds, reptiles, sharks, and insects. Create their own animal, make their own aquarium and feed the tarpon at the harbor.

    I drove a taxi for extra money east of Toronto thirty years ago. Each time a taxi drove up to the front of the Greenwood Racetrack, a group of local kids would run along the sidewalk angling for position by the passenger door. One lucky kid, or rather, the most aggressive one, would open the passenger door and say "Good luck, Mister!" The man getting out of the cab would vaguely say thanks and throw the kid a quarter. It was a routine everybody knew.

    Throughout the summer, one kid caught my eye. He was bigger than most of all the other kids but pushed away by even the smallest. He never made it but never gave up. One day, his chance arrived. As I was pulling up to the sidewalk, all the kids were pushing for a cab just ahead of mine. The boy saw me and walked toward my taxi. As I positioned the passenger door right beside him, he never paused and opened the passenger door, warmly saying, "Good luck, Mister!"

    But the man neither said thanks nor flipped him a quarter. He pushed him aside so hard that the boy fell on the sidewalk. I knew it hurt him badly. I got out in less than 10 seconds, but the man was gone in the crowd. So I looked for the kid. I decided to give him $20 for the effort. By the time I spotted him he was far up ahead, walking away in the opposite direction through the crowd and his head hanging down. When I got the cab turned around I lost sight of him. I never saw him again. I'd like to find him one day and tell him that if only he had stuck around a little longer I would have given him a whole $20.

    I learned from this kid that when things seem so hopeless that you are ready to give up, it's the time when things are most likely to turn around for you.
