A Hobby is a regular activity that is done for enjoyment, typically during one's leisure（闲暇的） time. By continually taking part in a particular hobby, one can acquire practical skill and knowledge in that area. Is travel a good hobby? Travel, in the youngest sort, is a part of education and, in the elder, a part of experience. Some may think otherwise. To them, visiting churches, castles, libraries, etc. is an absolute wastage of time. They may further say that one can read the account of these or see the films of the important places of the world. They forget that touch of actuality gives a different type of sensation and satisfaction.

    Travelling may be an expensive hobby but it makes up for the financial loss. If a traveller has interest in life and its manifestations（表现）, one can find much to keep oneself absorbed and happy. A student of any stream can definitely find something of his own interest and studies. One can definitely find everything that satisfies his cravings for knowledge and feelings.

    As a hobby, travelling keeps us busy during leisure time; it is the best method to make use of time. Till a person breaks from dull routine, physically and mentally, one cannot find satisfaction. Travelling helps us to achieve this break. At a new place, one is curious to know and eager to gather all the unknown information about the place which he has neither read nor heard before and he gets thrills and surprises which keep the interest and enthusiasm alive and encourage us to keep our journey on.

    While travelling, one comes across a number of people from varied backgrounds and places. By interacting with them, he comes to know about their traditions also. In case one has psychological bent of mind, one increases one's experience and power to understand others. Understanding human nature is, perhaps, the best part of education. Travelling satisfies all demands of a good hobby-it is absorbing education and refreshment to the mind, body and soul.

    The world has lost one of its brightest stars. British physicist Stephen dies on March 14, at the age of 76.

    Hawking is probably the world's most famous scientists after Albert Einstein. He is an expert on black holes. He has devoted his whole life to digging into the beginning (and the end) of the universe. “My goal is simple,” Hawking once said. “It is to completely understand the universe, why it is as it is and why it is there at all.”

    Hawking's achievements are even greater if you think about his disability. When he was 21, Hawking caught a bad illness that slowly stopped him form moving or talking. For a period of time, he had no way to communicate except by blinking（眨眼）. Later he sat on a wheelchair with a computer by his side. To communicate, he moved two fingers to control the computer's mouse. He selected his words from the screen, which were then spoken by a voice synthesizer（音响合成器）.

    “I have had the disease for most of my life,” Hawking once said. “Yet it has not stopped me from being successful at my work.”

    Though Hawking was a disabled man, he made great achievements. He received many awards and prizes for his work during his lifetime. This included winning the Albert Einstein Award, which stands for the highest achievement in theoretical physics.

    Despite the fact that he's no longer with us, his legacy will surely live on. As Sajid Javid, a UK government minister, put it, “A brief history on Earth; an eternity in the stars.”

    Like people, plants experience stress. And also, like people, the response to that stress can determine success.

    Bad environmental conditions, such as drought, flood, heat and other stresses, affect yields (产量) more than crop pests and diseases. We are trying to find a way to equip plants with the ability to tolerate environmental stress and maintain high yields, said Stephen Howell, a professor of genetics and cell biology.

    Plant cells produce proteins (蛋白质) and ship them to different parts of the cell. Under normal conditions, these proteins are folded into their normal, healthy structures as they are produced. When a plant is under stress, its cells produce poorly folded or unfolded proteins. Then a built-in system senses this and “sets off an alarm in the cell,” said Howell.

    In response to the alarm, another protein (IRE1) starts working and creates a different process which activates (激活) the stress response genes whose products bring about defensive measures that help the plant survive.

    “As it turns out, responses that are activated under stress conditions actually inhibit the growth of plants,” said Howell. “This allows them to preserve their energy to survive the stress conditions.”

    For plants in the wild, this response is a help for survival, he said. In production of agriculture crops, however, this response reduces yields.

    “You don't want crop plants to stop growing,” Howell said. “You want them to continue to grow and produce even though they are under stress.”

    With the new understanding of this stress response, the next step may be to silence the alarm system, said Howell. “What may be important is to disable some of these stress responses. That may make the plant more productive under stress conditions.”

    Phil White has just returned from an 18,000-mile, around-the-world bicycle trip. White had two reasons for making this epic journey. First of all, he wanted to use the trip to raise money for charity, which he did. He raised ＄70,000 for the British charity, Oxfam. White's second reason for making the trip was to break the world record and become the fastest person to cycle around the world. He is still waiting to find out if he has broken the record or not.

    White set off from Trafalgar Square, in London, on 19th June 2004 and was back 299 days later. He spent more than l,300 hours in the saddle(车座)and destroyed four sets of tyres and three bike chains. He had the adventure of his life crossing Europe, the Middle East, India, Asia, Australia, New Zealand and the Americas. Amazingly, he did all of this with absolutely no support team. No jeep carrying food, water and medicine. No doctor. Nothing! Just a bike and a very, very long road.

    The journey was lonely and desperate at times. He also had to fight his way across deserts, through jungles and over mountains. He cycled through heavy rains and temperatures of up to 45 degrees, all to help people in need. There were other dangers along the road. In Iran, he was chased by armed robbers and was lucky to escape with his life and the little money he had. The worst thing that happened to him was having to cycle into a headwind on a road that crosses the south of Australia. For 1, 000 kilometres he battled against the wind that was constantly pushing him. This part of the trip was slow, hard work and depressing, but he made it in the end. Now Mr. White is back and intends to write a book about his adventures.

    A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops.

    Students are increasingly using laptops for note-taking because of speed and legibility(清晰度).But the research has found laptop users are less able to remember and apply the concepts they have been taught.

    Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes "mindlessly" by taking down word for word what the professors said

    In the first experiment, students were given either a laptop or pen and paper .They listened to the same lectures and were told to use their usual note-taking skills. Thirty minutes after the talk, they were examined on their ability to remember facts and on how well they understood concepts.

    The researchers found that laptop users took twice as many notes as those who wrote by hand. However, the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.

    The researchers' report said, "While more notes are beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears."

    In another experiment aimed at testing long-term memory, students took notes as before but were tested a week after the lecture. This time, the students who wrote notes by hand performed significantly better on the exam.

    These two experiments suggest that handwritten notes are not only better for immediate learning and understanding, but that they also lead to superior revision in the future.
