 When it comes to the world of computers, green computing is becoming one of the most popular trends. But, what is exactly is green computing?  

The term "green computing" is one that is being used in many different markets and areas all over the world in today's global technology. Yet, many computer users out there aren't sure what it means. Green computing is actually pretty easy to explain and to do—it is basically learning to use computer resources more efficiently to help the environment as well as making energy savings. The main goal of a green computing program is to reduce the use of energy and materials that harm the environment. Green computing helps to promote the use of biodegradable products and recycle computer parts whenever possible.

 Green computing started as early as 1992, when the EPA created Energy Star, which is a voluntary labeling program that promotes energy efficient computing equipment and technologies.  

It was because of this program that many computer manufacturers launched sleep mode and millions of computer users around the world began to adopt this policy to help save energy when they were not using their computers. The term "green computing" began to be used around the same time as well, and began to become a goal that more companies strive to meet over the years. There are several government agencies that have continued to help strive for better standards for computers and companies to help promote green promoting. Energy Star was actually revised in October of 2006 to make the requirements stricter for computers，and also implemented a ranking system for products. Because of these new requirements, there are over 20 states that have now established a special recycling program for old computers and electronics to help with green computing.

Many of today's IT systems are beginning to rely on both people and hardware to help push their computer systems toward a more green computing system to help both the company and others. This is a hard balance to achieve, as it has to satisfy users, management, and regulatory compliance(顺从). Even the disposal of computer waste is all managed so that everyone in the circle is happy with the outcome. Many companies are learning the best ways that they call go greener when it comes to their computing and also help their business in the process. While many home computer users may not be quite as familiar with green computing as large firms, this term is starting to become more mainstream all around the world and the requirements for new, better computers to help both the companies and the end users of the equipment, as well as our environment, are becoming more and more urgent.

  Grown-ups are often surprised by how well they remember something they learned as children but have never practiced still swim as well as ever ever since. A man when he gets back who has not had a chance to go swimming for years can in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star"。remember the story of Cinderella or Goldilocks and the Three Bears. 

  One explanation is the law of overlearning , which can be stated as follows: Once we have learned something, additional learning trials increase the length of time we will remember it. 

  In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn. 

  The multiplication tables(乘法口诀表)are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood. 

  The law of overlearning explains why cramming(突击学习)for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development. 

  About twenty of us had been fortunate enough to receive invitations to a film-studio(影棚)to take part in a crowd-scene. 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 movie-camera 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 in front taken on an island in the Pacific were shown on a glass screen. An actor and actress stood of the scene so that they looked trick like this, palm trees, sandy beaches, as if they were at the water's edge on an island. By a simple 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"! 

  Honey(蜂蜜)from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals unexpected helper — a little bird called a honey guide. 

The honey guide does not actually like honey, but it does like the wax (蜂蜡) in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.

  Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.

Whenever we hear about "the homeless", most of us think of the Developing world. But the 1 is that homelessness is everywhere. For example, how many of us would expect to see people living on the streets of a 2 country like Germany?

Kurt Muller and his wife Rita have spent eleven years making 3 for the homeless of Berlin, Germany's capital. They first4 one long hot summer when most Germans were 5 on holiday. Kurt and his wife stayed at home, made sandwiches, 6 a table in the street and gave food to the homeless.

The Mullers soon realized that food and clothing weren't 7 . "What these people also need is warmth and 8 ," says Rita. The Mullers didn't 9 to give their phone number to the street people and told them to phone anytime. Rita 10 there was somebody at home to answer the phone and their home was always 11 to anyone who couldn't face another night on the street.

 The couple were soon 12  all their time and money, so Kurt visited food and clothing companies to 13  donations. Today, over thirty companies 14  donate food and other goods to the cause and volunteers help to 15  them to the homeless. The public also give clothes and money and a shoe producer 16  new shoes. 

Kurt and Rita receive no 17 for their hard work. " We feel like parents," says Rita, "and parents shouldn't18 money for helping their children. The love we get on the streets is our salary." Though Rita admits she often gets 19 . She says she will continue with her work because she likes the feeling of having made a 20 in the world.
