You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belvaev 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 came 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(行人) 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's 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(埋地线) to protect from possible lightning 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 the 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.

    Nowadays there is less and less contact between the old and the young. There are many reasons for this, but the result is the same: increasing numbers of children without grandparents and old people who have no contact with children. And more old people who are lonely and feel use- less, along with more and more families with young children who desperately need more support. It's a major problem in many societies.

    That's why intergenerational programmes, designed to bring the old and the young together, are growing in popularity all over the world, supported by UNESCO and other local and international organisations. There are examples of successful initiatives all over the world. Using young people to teach IT skills to older people is one obvious example. Using old people as volunteer assistants in schools is another, perhaps reading with children who need extra attention.

    One successful scheme in France is combining a residential home for the elderly with a creche/nursery school in the same building. The children and the residents eat lunch together and share activities such as music, painting, gardening and caring for the pets which the residents are encouraged to keep. In the afternoons, the residents enjoy reading or telling stones to the children and, if a child is feeling sad or tired, there is always a kind lap to sit on and a cuddle (依偎). There are trips out and birthday parties too.

    The advantages are enormous for everyone concerned. The children are happy because they get a lot more individual attention and respond well because someone has lime, for them. They also learn that old people are not different or frightening in any way. And of course, they see illness and death and learn to accept them. The residents are happy because they feel useful and needed. They are more active and more interested in life when the children are around and they take more interest in their appearance too. And the staff are happy because they see an improvement in the physical and psychological health of the residents and have an army of assistants to help with the children.

    In a world with limited land, water and other natural resources (资源), the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.

    Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil (棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.

    The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.

    David Rees runs a truly distinctive business. He charges customers $15 to sharpen their pencils to perfections, using a variety of tools.

    I know what you're thinking﹣is this a joke? The 39﹣year﹣old gets asked that question a lot. To clarify everything, he even created a special section on his website telling everyone he's actually providing a real service.

    You can supply your own pencil or you can have Rees sharpen one of his own favorite 2B pencils. After that, he mails it to you in a display tube with the shavings in a separate bag, and an authentic certificate which just happens to mention the pencil is so sharp as to be a dangerous object.

    To achieve the desired result, the master sharpener uses all kinds of tools, including general sandpapers, pocket knives and even a special $450 sharpening machine. "It depends on what the customer wants to use his/her pencil for," he says. "That determines the most appropriate pencil﹣sharpening technique. Some customers buy pencils as inspirational symbols while others buy them because of their special memories of classic 2B pencils."

    $15 to have a pencil sharpened is a bit expensive though, right？ You're not the only one who feels that way, and David's unique business has really angered lots of people, who talk of inequality in America, saying it is so insane for the wealthy to pay $15 to sharpen a pencil. But others will say, "This is just our urge to put an end to the welfare state because new ideas arise along with the business."

    David admits his trade is sort of unusual. But there are those who actually value his service, as proven by the over 500 orders he has gotten.

    At first, Michael Surrell didn't see the black smoke or flames shooting from the windows of his neighbors' home. Then they got a call from one of his daughters: "The house next door is on fire!" He went over and saw three women crying madly on their porch (门廊).

    "The baby's in the second floor!" one of the women cried. Though the fire department had been called, Surrell, then 64, bravely ran inside. "The baby" was Tiara Roberts, the woman's granddaughter and a playmate of Surrell's three youngest kids.

Entering the burning house was like "running into a bucket of black paint," Surrell says. The thick smoke caused him to stumble blindly around, burned his eyes, and made it impossible to breathe. The conditions would have been dangerous for anyone, but for Surrell, who has chronic obstructive pulmonary disease(慢性阻塞性肺病), they were life-threatening.

    Taking a deep breath, he moved around in the overwhelming darkness. Because the house had a similar layout to his, he found the stairs and made it to the second floor. Then he heard a soft but clear moan. Still unable to see, Surrell fell to his knees on the hot wood floor. He crawled toward the sound, feeling around for any sign of the girl. Finally, he touched something. A shoe, then an ankle. He pulled Tiara toward him, scooped her into his arms and stood. Turning, he fought through the smoke and ran blindly into the blackness…

    Surrell woke up in the hospital a couple of days later and spent over a week in the hospital. Tiara was released from the hospital after a few days. The fire worsened Surrell's pulmonary condition, and he feels the effects even two years later. As a result, he takes extra medication that helps open his airways. "It's a small price to pay," he says. "I'd do it again in a heartbeat. I wouldn't give it a second thought."

    Some people have a very poor sense of direction. Unluckily, I am one of them. I have visited a place many times but I may still get lost there the next time.

    When I was a little girl, I never dared to ask strangers the way. And so I used to walk around in circles and hope that by chance I would get to the place I was going to.

    Now, I am no longer too shy to ask people for directions, but I often receive helpless or even wrong information. So I try to avoid giving people wrong directions. If anyone ever asks me the way somewhere, I would say, "Sorry, I am a stranger here."

    Once on my way to work I was stopped by a man. He asked me if I could tell him the way to the Friendship Building. I gave him my usual reply. But just as I walked on only a few steps, I realized that he had asked the way to my office building. However, I had no time to turn back and look for him. I was rushing to meet with someone at my office and I didn't want to keep him waiting.

    When I just got to my office, the secretary(秘书) showed in the man who had asked me for directions. Imagine how embarrassed I was and how surprised he was when we saw each other at the first sight.
