I grew up poor. We had little money, butplenty of love and attention. I understood that no matter how poor a person was, they could still afford a dream. My dream was athletics.

    By the time I was sixteen, I was good at baseball and football. My high-school coach was Ollie Jarvis. He not only believed in me, but taught me the difference between having a dream and showing conviction（信念）.

    One summer a friend recommended me for asummer job. This meant a chance for money in my pocket — cash for dates withgirls, certainly, money for a new bike and new clothes, and the start of savings for a house for my mother.

Then I realized I would have to give up summer baseball to handle the work schedule, and that meant I would have to tell Coach Jarvis I wouldn't be playing. I was dreading（害怕）this, but my mother said: "If you make your bed, you have to lie in it."

When I told Coach Jarvis, he was as madas I expected him to be. "Your playing days are limited. You can't afford to waste them," he said.

   I stood before him with my head hanging, trying to think of the words that would explain to him why my dream of buying my mom a house.

"How much are you going to make at this job, son?" he demanded.

"Three twenty-five an hour," I replied.

"Well," he asked, "is $3.25 an hour the price of a dream?"

    That question laidbare for me the difference between wanting something right now and having agoal. I devoted myself to sports that summer, and within the year I was drafted by the Pittsburgh Pirates to play rookie-league ball, and offered a $20,000 contract. I signed with the Denver Broncos in 1984 for $1.7 million, and boughtmy mother the house of my dream.

    About twenty of us had been fortunate enough to receive invitations to a film­studio (影棚) to take part in a crowd­scene. Although our “act” would last only for a short time，we could see quite a number of interesting things.

    We all stood at the far end of the studio as workmen prepared the scene，setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big movie­camera was wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in “snow”. Two more fans were turned on，and a “strong wind” blew through the trees. The picture looked so real that it made us feel cold.

    The next scene was a complete contrast (对比). The way it was filmed was quite unusual. Pictures taken on an island in the Pacific were shown on a glass screen (幕). An actor and actress stood in front of the scene so that they looked as if they were at the water's edge on an island. By a simple trick like this, palm trees, sandy beaches, and blue, clear skies had been brought into the studio!

    Since it was our turn next，we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film “stars”！

    "The history of the world is but the biography (传记) of great men," argued Thomas Carlyle, the advocate of what has come to be known as the "Great Man Theory of History." This theory suggests that the broader movements and outline of history all go back to the leadership of great individuals who had unique influence on their times. Whether or not Carlyle's theory proves true is debatable, but that certain individuals cast long shadows is not.

    As one who is entrusted with a leadership position, I find it profitable to read of others who have led. Wherever you find me, you'll likely find a good biography nearby. Why is this the case? First, I find good biographies fascinating. I'll occasionally read a novel, but I've never been overly drawn to fiction. I have found myself unable to sleep while in the struggle of the Battle of Britain in William Manchester's The Last Lion. For me, not to read biographies would rob me of pleasure in my life.

    Second, I find good biographies informative. A good biographer tells not only the story of a person, but also of their times. Reading a good biography is like wandering through an intellectual shopping mall. The first store is what drew you there, but you will be pleasantly surprised along the way at what other items grab your attention. You'll find no better account of the British Empire at its peak than the opening chapters of Manchester's Visions of Glory, volume one of his The Last Lion. Strictly speaking, a biography is but a slice of history.

    Third, I find good biographies relaxing. Winston Churchill once noted a man who works with his hands should have a hobby that engages his mind, and a man who works with his mind should have a hobby that engages his hands. Another way to apply Churchill's saying is to combine technical, pen-in-hand vocational reading with leisurely biographical reading. Indeed, few things are more relaxing to me than winding down the evening and entering into another world.

    This is why I love reading good biographies, and why I pity the person who neglects them. Don't be counted among their number.

    When my father married my mother in 1943, he gave my mother a 1937 crown coin and told her to keep it in the back of her purse and not to spend it. This would mean that she always felt that she was protected and would always have money if she really needed it.

    When I was married in 1970 my husband who had heard this story, obtained a 1937 crown coin for me and I have always kept it in my wallet, and I have always had enough for my needs.

    A friend recently fell on hard times, partly through external (外部的) circumstances and partly through poor planning. Friends and I have loaned her money, paid her bills, given her food, and even tried to teach her budget techniques, but none of them has been a solution. She has just slipped deeper and deeper into financial trouble and depression.

    Last week she looked pale and unwell, very depressed and hopeless, very sad for a friend to see and I then thought about how the crown coin, a physical reminder of another's care and love had protected me, so I went to the bank for a $ 100 dollar-bill.

    I told my friend the story and asked her to keep the $ 100 in the back of her wallet. It turned out that she didn't have a wallet, so she put the money in a little pencil case where she kept her coins. She immediately felt better—"I feel rich, and thank you for being a good friend," she said, and we were both a bit teary.

    I went home and remembered a little wallet I had that I'd never used, and thought, "I'll give that to my friend." I opened it, and inside, found $ 100.

    American and British people both speak English of course. But sometimes it does not seem like the same language. In fact, there are some important differences between British English and American English.

    First of all, they sound very different. Often, Americans don't say each word separately. They say several words together. Americans may say "I dunno" instead of "I don't know". Or they may say "Whaddaya say?" instead of "What do you say?" However, the British are more careful in their speech. They usually say all the words and keep them separate.

    Sound is not the only difference between British English and American English. Words sometimes have different meanings too. Some American words are never used in England. The same thing is true of some British words in America. For example, the vocabulary for cars and driving is very different. Americans drive trucks, but in England people drive lorries.

    Many expressions are also different in the two countries. In England，if you are going to telephone your friends, you "phone them up". In America, you "give them a call". When you are saying goodbye in England you might say "Cheerio!" In America you might say "See you later."

    There're also some differences in grammar. For example, Americans usually use the helping verb "do" when they ask a question. They say "Do you have a storybook?" But the British often leave out the helping verb. They say "Have you a storybook?"

    All these differences can be confusing if you are learning English. But most languages are like this. Languages change over time. When people live in separate places, the languages change in different ways. This is what has happened to English. It can also happen to other languages, such as French. Many people in Canada speak French, but their French is very different from the French of France.

    A new officer with the Huntington Park Police patrols (巡逻) local parks 24 hours a day seven days a week. He doesn't need rest, coffee breaks, a salary or medical insurance, and that is because it is a Robocop.

    The main function of the Robocop is to scan and film the surroundings. Besides cameras with night vision that report 360 degrees, it also has a distress button which is located here, so if somebody is to need assistance or they want to contact the communication center, they can do it by way of that distress button. There are people that are monitoring on the other end.

    This newest police employee is self-charging. It's easy to program it and make changes to the software if necessary. Its maintenance (维护) costs are roughly 75 thousand dollars a year. It travels the entire park. It is a programmed path, but the police are able to change the path and adapt it.

    The Robocop can record the license plates (车牌) of passing cars and check them against an online database of stolen cars. It can also help locate a lost iPhone because it is able to determine a smartphone's MAC address. The police can see from the robot if something wrong happens and then come and figure it out.

    The Robocop can't replace its human handlers. The whole goal is to give police more time to do things machines can't do. The police have been having some concerns about safety of the parks and want an extra set of eyes that will help patrol a 24/7.Robocop's creators believe this model known as K5 is best used for providing security at public places like hospitals, parking lots, parks and airports. So far, it seems to be working out just fine.
