My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn't fit. I let a salesclerk fool me into buying a discontinued model. I realized this a day late, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautifully when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn't got any channels showing all-night movies or I would never have gotten to bed.

    Then I started developing a problem with the set that involved static (静电) noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉) shaking my set.

    When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my fist, and it stopped working altogether .My trip to the repair shop cost me $62, and the set is working well now, but I keep expecting more trouble.

    Our room was on the second floor but you could still hear the roar of the ocean and see the stars at night. I used to take long walks along the water. The food in town was wonderful and the people were very friendly. The area was very quiet and peaceful, and fairly deserted.

    The last evening of our vacation, however, we all heard strange footsteps following closely behind us as we were walking up to our room in the holiday centre. We turned around and noticed a fairly young man moving very rapidly across the beach and getting closer to us. He was tall and wore a baseball cap. We didn't have any cell phones on us. I never saw Dad as worried as he was then and knew that something was terribly wrong. The sense of fear started to overwhelm Mom and me. We had had such a good time in town. Now, the night was rapidly turning into a dangerous situation.

    We could hear the man's footsteps getting closer. Dad's face was almost pale. The so-called intruder (侵入者) had moved nearer and nearer when all of a sudden, the nearby vending (自动贩卖) machine started going crazy and spitting out cans of soda! The noise actually scared the intruder and he ran out of sight. My parents were shaking, but we all turned around to see who had put money into the vending machine downstairs, and actually saved us, but no one was around at all.Not a soul.

    It's one vacation I will never forget.

    Nervous suspects locked up in Britain's newest police station may feel relieved by a pleasant yellow color on the door . If they are close to confessing（供认）a crime , the blue on the wall might tip the balance .

    Gwent Police have abandoned colors such as greys and browns of the 20th-century police cell（牢房）and have used color psychology to decorate them .

    Ystrad Mynach station , which recently opened at a cost of ￡5 million has four cells with glass doors for prisoners who suffer from claustrophobia（幽闭恐怖症）. Designers have painted the frames yellow , which researchers say is a calming color . Other cells contain a royal blue line because psychologists believe that the color is likely to encourage truthfulness .

    The station has 31 cells , including 12 with a “live scan” system for drunken or disturbed prisoners , which detects the rise and fall of their chest . An alarm alerts officers if a prisoner's breathing stops and carries on ringing until the door is opened .

    Designers and psychologists have worked for years on color . Blue is said to suggest trust , efficiency , duty , logic , coolness , thinking and calm . It also suggests coldness and unfriendliness . It is thought that strong blues will stimulate clear thought and lighter , soft colors will calm the mind and aid concentration .

    Yellow is linked with confidence , self-respect and friendliness get the color wrong and it could cause fear , depression and anxiety , but the right yellow can lift spirits and self-respect .

    Ingrid Collins , a psychologist who specializes in the effects of color , said that color was an “ energy force ” . She said : “ Blue does enhance communication but I am not sure it would enhance truthful communication . ”

    Yellow , she said , affected the mind . Red , on the other hand , should never be considered because it could increase aggression . Mrs. Collins praised the designers for using colors in the cells . Gwent is not the first British force to experiment with color to calm down or persuade prisoners to co-operate , In the 1990s Strathclyde Police used pink in cells based on research carried out by the US Navy .

    I passed a man on the way home from work this evening. He was walking down the side of the carriageway. Actually, he was walking unsteadily. I slowed down wondering whether to stop and give him a lift, at least down to a safer part of the road. I couldn't be sure but he appeared to be quite drunk. I pulled over and watched him in my rear-view mirror. He was obviously well-oiled. A truck turned sharply to avoid him at one point-he didn't appear to care.

    Having stopped now, I thought I might as well wait for him to reach the car. Five minutes went by and he reached the car. My windows were down, and I asked him if he wanted a lift. He indicated that he was going to the next town, just out of my way, but not far enough to put me to trouble. So in he got.

    “Sorry, I'm really quite drunk. I've been at a funeral. My family are all really out of it, so I decided to walk home. I'm Ryan,” and he offered me his hand. I drove and we talked. He told me he'd buried his uncle, and that he was a traveler.

    He called me brother and offered me his cool shades as payment. I declined and said the joy was in the giving. Three times along the way he told me that, “Whatever we put out there comes back to us. Something good will come to you for picking me up.” We told each other where we came from, the places we've lived, and how we both ended up here. He apologized again for being so drunk. “Anywhere around here is fine for me,” he said. So I dropped him at the next junction. We shook hands and spoke each other's names again.

    I felt as if I'd been blessed somehow. I think I have been.

    Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.

    Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.

    This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.

    Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Sure we all know that we're the apple of our parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will go to the Olympics. But sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you should build a positive self-image and learn to love yourself.

    Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about US. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.

    The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it.

    It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't mean it's true.

    The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat (拍) yourself on the back, you'll know you're well on your way. Good luck!
