At the age of ten I could not figure out what this Elvis Presley guy had that the rest of us boys did not have. I mean, he had a head, two arms and twolegs, just like the rest of us. About nine o'clock on Saturday morning I decided to ask Eugene Correthers, one of the older boys, what it wasthat made this Elvis guy so special. He told me that it was Elvis' wavy hair and the way he moved his body.

    About half an hour later all the boys in the orphanage(孤儿院) were called to the main dining-room and told we were all going to downtown Jacksonville, Florida to geta new pair of Buster Brown shoes and a haircut. That is when Igot this big idea, which hit me like a ton of bricks. If the Elvis hair cut was the big secret, then that's what I was going to get.

    All the way to town I told everybody, including the matron(女管家) from the orphanage who was taking us to town, that I was going to look just like Elvis Presley and that I would learn to move around just like he did and that I would be rich and famous one day, just like him.

    When I got my new Buster Brown shoes, I could hardly wait for my new hair cut and now that I had my new Busier Brown shoes I would be very happy to go back to the orphanage and practice being like Elvis.

    We finally arrived at the big barber shop, where they cutour hair for free because we were orphans(孤儿). I looked at the barber and said, “I want an Elvis hair cut. Can you make my hair like Elvis?”I asked him, with a bigsmile on my face. “Let's just see what we can do for you, little man,”he said. I was so happy when he started to cut my hair. Just as he started to cut my hair, the matron signed for him to come over to where she was standing. She whispered something into his ear and then he shook his head, like he wastelling her“No”. Then he toldme they were not allowed to give us Elvis hair cuts. Then I saw my hair falling onto the floor

    I had an experience some years ago, which taught me something about the ways in which people make a bad situation worse by blaming themselves. One January, I had to hold two funerals on successive days for two elderly women in my community. Both had died “full of years”, as the Bible would say. Their homes happened to be near each other, so I paid condolence(吊唁) calls on the two families on the same afternoon.

    At the first home, the son of the deceased(已故的)woman said to me, “If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today. It's my fault that she died.” At the second home, the son of the other deceased woman said, “If only I hadn't insisted on my mother's going to Florida, she would be alive today. That long airplane ride, the sudden change of climate, was more than she could take. It's my fault that she's dead.”

    You see that any time there is a death, the survivors will feel guilty. Because the course of action they took turned out bad, they believe that the opposite course would have turned out better. After all, how could it have turned out any worse?

    There seem to be two elements involved in our willingness to feel guilty. The first is our pressing need to believe that the world makes sense, that there is a cause for every effect and a reason for everything that happens that leads us to find patterns and connections both where they really exist and where they exist only in our minds. The second element is the view that we are the cause of what happens, especially the bad things that happen. It seems to be a short step from believing that every event has a cause to believe that every disaster is our fault. The roots of this feeling may lie in our childhood.

    A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. He wakes up in the morning and summons the rest of the world to its tasks. He cries, and someone comes to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not completely outgrow that childish view that our wishes cause things to happen.

    The Nazca Lines are a series of large ancient geoglyphs (地画) in the Nazca Desert, in southern Peru. It is ranging from geometric patterns to drawings of different animals and stylized human-like forms. The ancient lines can only be truly taken in from high in the air, leaving generations puzzled as to how these precise works could have been completed long before the documented invention of human flight.

    The Lines were first spotted when commercial airlines began flying across the Peruvian desert in the 1920,s. Who built them and what was their purpose? Are they roads, star pointers，maybe even a gigantic map? If the people who lived here 2,000 years ago had only a simple technology, how did they manage to construct such precise figures? Did they have a plan? These markings are like a vast puzzle.

    The Nazca Lines are the most outstanding group of geoglyphs in the world. There are also huge geoglyphs in Egypt, Malta，United States (Mississippi and California), Chile，Holivia and in other countries. But the Nazca geoglyphs, because of their numbers， characteristics, dimensions and cultural continuity as they were made and remade throughout a certain history period, form the most impressive archeological (考古学的) group.

    The Nazca plain is unique for its ability to preserve the markings upon it, due to the combination of the climate (one of the driest on Earth, with only twenty minutes of rainfall per year) and the flat, stony ground which minimizes the effect of the wind at ground level. With no dust or sand to cover the plain and little rain or wind to erode (腐蚀) it, lines drawn here tend to stay drawn. These factors, combined with the existence of lighter-colored subsoil beneath the desert surface, provide a vast writing pad that is suited to the artist who wants to leave his mark eternal.

    A new study suggests climate conditions in the Sahara Desert, one of hottest, driest and most deserted areas in the world, have changed from wet to dry a about every 20,000 years.

    But previous evidence has suggested the Sahara did not always experience such extreme heat and dry conditions. At times, the Sahara Ranged to a very wet climate. This permitted plants and animals to develop and grow and led to the creation of human settlements. Now, they have discovered more evidence, which, the lead researcher David Mc Gee says, supports the idea that the Sahara's climate kept changing between wet and dry about every 20,000, years.

    McGee reported these climate changes were mainly driven by changes in the Earth's(地轴)as the planet travels round the sun .This process affects the amount of sunlight between seasons. Every 20,000 years the Earth receives more strong summer sunlight. When the Earth's axis changes again, the amount of sunlight is reduced. This season change happened continuously every 20,000 years. The other part of the season produced rainy conditions, resulting in a wetter, greener, plant-rich environment. When the rainy activity weakens, the climate becomes hot and dry, like the Sahara remains today.

    The scientists based their research on dust collected from ocean sediment(沉积物)in the Atlantic Ocean bottom off the coast of West Africa. The dust contained layers (层)of ancient sediment built up over millions of years. Each layer could contain traces of Saharan dust as well as the remains of life forms. This information was used to assess over what time period the dust had built up. This led to the overall finding that the Saharan changes from wet to dry climates happened every 20,000 years.

David McGee said that today we only see the Sahara Desert as an extremely deserted and "inhospitable" place. The new study suggests that the area's climate has changes between grasslands and a much wetter environment, and back to dry climates, even over the last quarter million years. McGee says he thinks the latest research can be valuable in studying the Sahara's history as it relates to human settlement.

    With the explosion of consumer choices in recent history, the latest must-haves would surely need to be upgraded more often than every 10 years. In 2002 a computer and basic mobile phone would have been enough for most people, but now? The public need a trendy notebook computer and a smart phone with WiFi connection to feel they are up-to-date. So when will we have enough things? When will we finally be happy? Well, it looks like the things we buy today will barely keep us satisfied for a few months.

    In the eyes of some psychologists, far from making us happy, greater consumer choice creates many serious psychological problems. A fundamental principle of the society is that more freedom is better and more choice in the marketplace means more freedom. Therefore more choice leads to more happiness. This is not the case, however.

    Imagine you go to a café offering chocolate and vanilla ice cream. You choose the chocolate and eat it happily. But what if the café serves 50 kinds of ice cream? You choose chocolate and then start to worry, "maybe blueberry would have been better, perhaps the half-fat ice cream would have been healthier. Stupid me, all these choices and I didn't make the best one! "

    In China's major cities we have now passed the point where more consumer choice is making us happier. We are annoyed by all the options we have, disappointed because our expectations are so high and angered at ourselves when we don't make a perfect choice every time.

    A newspaper reporter tells a story about traveling on a plane with high-speed Internet access. He thought this was amazing—the newest piece of technology he had heard of. Then the service went down. The man next to him was angry and swore. The reporter thought, "How quickly the world owes him something he knew existed only 10 seconds ago!"

We are all stuck in the thought of having satisfying relationships, which bring some meaning to our lives and make us happy. We are so busy in finding true happiness that we often forget true happiness lies within us.

You have to love yourself first in order to love someone else. We have heard in countless inspiring speeches that self-love is the basis of a happy life. Have you ever wondered that with so many people advertising self-love, why haven't we been able to love ourselves?

One of the reasons for our failure to love ourselves is that we have been taught to be selfless from the start of time. The minute we start thinking about ourselves, everyone around us makes it their personal mission to remind us of how selfish we are. However, there is nothing wrong with putting your needs and yourself first. Self-love is not selfish. It only helps us better understand which sacrifices (牺牲) are worth making!

Actually, self-love and healthy relationships cannot be separated. Self-love is the very core of any healthy relationship. Now you might wonder how my love for myself is going to make me able to have a healthy relationship. Isn't a healthy relationship all about giving? Honestly, No.

When you know your worth, you know what you are willing to accept in a relationship and what not. You will know where to draw boundaries because you value your own opinions. You will have a clear understanding of what you need, what are your values and your limits. From now on, you should realize that true happiness lies within you and you shouldn't waste time and effort searching for peace and joy in the world outside.
