You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet. That's why he created lampbrella, a lamp post with its own rain- sensing umbrella.

    The designer says he come up with the idea after watching people get wet on streets in Russia. “once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy (伞蓬) built into a street lamp.” he said.

    The lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors (传感器) then ensure that the umbrella offers pedestrians shelter whenever it starts raining.

In addition to the rain sensor, there's also a 360° motion sensor on the fiberglass street lamp which detects whether anyone is using the lampbrella. After three minutes of not being used the canopy is closed.

     According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lighting strike. Each lampbrella would offer enough shelter for several people. Being installed (安装) at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.

      While there are no plans to take lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.

    Agatha Christie used to go out at night. She will never forget the night when she met a robber(盗贼) many years ago.

    That evening, she was invited to a birthday party which lasted till 2 o'clock in the morning. Without company, Agatha walked home along the quiet street. Suddenly from the shadow of a dark building, a tall man with a sharp knife in his right hand ran out at her. "Good morning, lady," the man said in a low voice, "I don't think you wish to die here!" "What do you want?" Agatha asked.

    "Your earrings (耳环). Take them off!" Agatha suddenly had a bright idea. She tried to cover her necklace with the collar (衣领) of her overcoat while she used the other hand to take off both of her earrings, and then she quickly threw them on the ground.

    "Take them and let me go." she said. The robber was uncertain. He saw that the girl didn't care for the earrings at all, only trying to protect the necklace. He realized the necklace would cost more, so he said, "Give me your necklace."

    "Oh, sir. It's not worth much. Please let me keep it."

    "Stop talking rubbish. Quick!"

    With shaky hands, Agatha took off her necklace. As soon as the robber disappeared, she picked up her earrings and ran as fast as she could to her home.

    The earrings cost 480 pounds and the necklace the robber had taken away cost only six pounds ten shillings (先令).

    When I was five or six years old, I remember watching TV and seeing other children suffer in other parts of the world. I would say to myself, "When I grow up, when I can get rich, I will save kids all over the world."

    At 17, I started my career here in America, and by the age of 18, I started my first charity organization. I went on to team up with other organizations in the following years, and met, helped, and even lost some of the most beautiful souls, tern six-year-old Jasmina Anema who passed away in 2010 from leukemia (白血病), whose story inspired thousands to volunteer as donors, to 2012 when grandmother lost her battle with cancer, which is the very reason and the driving force behind the Clara Lionel Foundation( CLF). We're all human. And we all just want a chance: a chance at life, a chance in education, a chance at a future, really. And at CLF, our mission is to impact as many lives as possible, but it starts with just one.

    People make it seem too hard to do charity work. The truth is, you don't have to be rich to help others. You don't need to be famous. You don't even have to be college-educated. But it starts with your neighbor, the person right next to you, the person sitting next to you in class, the kid down the block in your neighborhood. You just do whatever you can to help in any way that you can. And today, I want to challenge each of you to make a commitment to help one person，one organization，one situation that touches your heart. My grandmother always used to say, "If you've got a dollar, there's plenty to share."

    JERUSALEM—Israel's Environmental Protection Ministry asked citizens Wednesday to avoid unnecessary physical activity and stay indoors, as a serious sandstorm struck the Middle East in a thick yellow haze (霾) for a second day with no hope to see things clearly.

    The ministry said heavy levels of dust and sand in the air were a threat to cities throughout the country. The ministry's website advised pregnant women, the elderly and those with heart and respiratory (呼吸的) conditions to stay indoors, and asked schools to keep children indoors.

    The emergency service Magen David Adom reported that it has treated more than 300 Israelis suffering from breathing problems, and that hospitals have more respiratory-related patients, including a large number of the elderly and those with asthma and related conditions.

    The domestic Israeli airlines Arkia and Israir continued to ground their flights to Eilat because of reduced visibility.

    The sandstorm has affected Egypt, Jordan, Iraq, Lebanon and Syria, where at least five deaths have been reported.

    "There has been nothing that came close to the magnitude of this sandstorm," said Daniel Rosenfeld, a professor with the Institute of Earth Sciences at the Hebrew University in Jerusalem.

    "While Israel has experienced a number of sandstorms in the past, they started from the Sinai Desert and the Sahara Desert to the south and were joined by winter windstorms that cleared the air," he said. In this case, the storm comes from Syria and Iraq to the north and east.

    Because the storm is hitting during the summer, at a time of both little wind and severe heat and humidity, forecasters expect the particles to remain in the air throughout the weekend and possibly into next week.

    "This is really puzzling," said Rosenfeld, adding that he and his colleague will conduct research into the origins of the unprecedented (前所未有的) storm. (326 words)

    "The history of the world is but the biography (传记) of great men," argued Thomas Carlyle, the advocate of what has come to be known as the "Great Man Theory of History." This theory suggests that the broader movements and outline of history all go back to the leadership of great individuals who had unique influence on their times. Whether or not Carlyle's theory proves true is debatable, but that certain individuals cast long shadows is not.

    As one who is entrusted with a leadership position, I find it profitable to read of others who have led. Wherever you find me, you'll likely find a good biography nearby. Why is this the case? First, I find good biographies fascinating. I'll occasionally read a novel, but I've never been overly drawn to fiction. I have found myself unable to sleep while in the struggle of the Battle of Britain in William Manchester's The Last Lion. For me, not to read biographies would rob me of pleasure in my life.

    Second, I find good biographies informative. A good biographer tells not only the story of a person, but also of their times. Reading a good biography is like wandering through an intellectual shopping mall. The first store is what drew you there, but you will be pleasantly surprised along the way at what other items grab your attention. You'll find no better account of the British Empire at its peak than the opening chapters of Manchester's Visions of Glory, volume one of his The Last Lion. Strictly speaking, a biography is but a slice of history.

    Third, I find good biographies relaxing. Winston Churchill once noted a man who works with his hands should have a hobby that engages his mind, and a man who works with his mind should have a hobby that engages his hands. Another way to apply Churchill's saying is to combine technical, pen-in-hand vocational reading with leisurely biographical reading. Indeed, few things are more relaxing to me than winding down the evening and entering into another world.

    This is why I love reading good biographies, and why I pity the person who neglects them. Don't be counted among their number.
