With the development of science and technology, people find it increasingly difficult to keep pace with the most fashionable smart phones in the world, especially when smart phones are connected with robots. If any robot can take over the world, it's RoBohon. He has all the information you put in your smart phone and can read human feelings. So everyone probably wants to own the cutest smart robot phone.

    RoBohon is very useful. He can project photographs and films, tell you he loves you if he senses you are crying and do everything your smart phone can do.

    RoBohon was created by Japanese electronics company SHARP. The robot phone, with a 2-inch screen fitted into its back, stands 20cm tall and weighs 390 grams. Most surprisingly, he can walk on his own legs around your home and act as a super cute personal assistant. He can even dance. He reads your text messages, announces phone calls, dries your tears and wakes you up. He can even recognize your face and call your name when you enter the room. He will be always at your side keeping you company and providing you with great comfort.

    RoBohon can also serve as an alarm clock. The robot can be a wonderful partner in a small conversation. Though he is expensive, more than double the price of iPhone, who wouldn't want a small personal assistant?

    In the world today, all of the people need recreation(消遣). We cannot work all the time if we are going to keep healthy and enjoy life.

    Everyone has his own way of relaxing. Perhaps the most popular form is to take part in sports. There are team sports, such as basketball and football. There are also individual(个人的) sports, such as swimming and running. Skating and mountain climbing are the most popular recreation for people who like to be outdoor. Not everyone who enjoys sports likes to take part in them. Many people like watching them on TV or listening to them on the radio. So many people like some forms of recreation, such as watching TV, singing and dancing. It doesn't matter whether we like indoor recreation or take part in outdoor sports. It is important for everyone to relax from time to time and enjoy some forms of recreation.

    Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.

    This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.

    This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.

    Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone (臭氧) levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.

    "We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere." Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

    Standing in line for the latest iPhone at the Apple store, queuing for tickets to the match or even just waiting at the post office might just have got a lot easier.

Japanese car-maker Nissan announces that it has just the thing to relieve the painful legs of tired queuers.

    The new system of self-driving chairs is designed to detect when someone at the front of the queue is called, and automatically move everyone else one step forward in line.

    The new invention is shown in a company video, which shows a busy restaurant with customers waiting outside. In the video, diners are sitting in a row of chairs, but will not have to stand when the next hungry diner is called to a table. Instead, the chairs, equipped with autonomous technology that detects the seat ahead, move along a path toward the front of the line. When the person at the front of the queue is called, the empty chair at the front can sense it is empty and so moves out of line. Cameras on the remaining chairs then sense the movement and follow automatically.

    "The system, which is similar to the kind used in Nissan's autonomous vehicle technology, will be tested at select restaurants in Japan this year," Nissan said. "It appeals to anyone who has queued for hours outside a crowded restaurant: it rids the boredom and physical pain of standing in line," Nissan added.

    Although Tokyo has some 160,000 restaurants, long queues are not uncommon. Chosen restaurants that meet the criteria will be able to show the chairs outside their restaurants next year. Nissan also released a short video showing the chairs being used in an art gallery, moving slowly in front of the various paintings to let viewers appreciate the art without the need to stand up.

    One morning, a blind boy sat on the steps of a building with a hat by his feet. He held a sign which said, "I am blind, Please help me."

    There were only a few coins in the hat. A man was walking by. He took out a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words on it. He put the sign back so that everyone who walked by could see the news words.

    Soon the hat began to fill up. A lot more people were giving the money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy recognized his footsteps and asked." Are you the one who changed my sign in the morning? What did you write?

    The man said, "I only wrote the truth. I said what you said, but in a different way." What he had written was, "Today is a beautiful day, but I can not see it."

    Do you think the first sign and the second sign were saying the same thing?

    Of course both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the beauty of the day, but the boy could not enjoy it because he was blind.

    The first sign simply said the boy was blind, while the second sign told people they were so lucky that they were not blind. There are at least two lessons we can learn from this simple story.

    The first is: Treasure what you have. Someone else has less. Try your best to help those who need your help.

    The second is: Be creative. Think differently. There is always a better way.

    College graduation brings both the satisfaction of academic achievement and the expectation of a well-paid job. But for 6, 000 graduates at San Jose State this year, there's uncertainty as they enter one of the worst job markets in decades. Ryan Stewart has a freshly-minted (新兴的) degree in religious studies, but no job prospects.

    "You look at everybody's parents and neighbours, and they're getting laid off and don't have jobs," said Stewart. "Then you look at the young people just coming into the workforce... it's just scary."

    When the class of 2003 entered college, the future never looked brighter. But in the four years they've been here, the world outside has changed dramatically.

    "Those were the exciting times, lots of dot-com opportunities, exploding offers, students getting top dollar with lots of benefits," said Cheryl Allmen-Vinnidge of the San Jose State Career Center. "Times have changed. It's a new market."

    Cheryl Allmen-Vinnidge ought to know. She runs the San Jose State Career Center, sort of a crossroads between college and the real world. Allmen-Vinnidge says students who do find jobs after college have done their homework.

    "The typical graduate who does have a job offer started working on it two years ago. They've postured (定位) themselves well during the summer. They've had several internships (实习)," she said. And they've majored in one of the few fields that are still hot, like chemical engineering, accounting, or nursing, where average starting salaries have actually increased over last year. Other popular fields (like information systems management, computer science, and political science) have seen big declines in starting salaries.

    Ryan Stewart (he had hoped to become a teacher) may just end up going back to school. "I'd like to teach college some day and that requires more schooling, which would be great in a bad economy," he said.

    To some students, a degree may not be a ticket to instant wealth. For now, they can only hope its value will increase over time.
