Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy. Apart from this, studies are being carried out to harness(利用) usable windenergy produced by man-made technologies.

    One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train, which produces fierce wind that can betrans formed into electricity.

    According to Pradhan's proposal, with a few small improvements in existing trains running in Mumbai, the largest city in India, at least 10,000 megawatts(兆瓦) of electricity could be harvested each day.

    Building on this principle, designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device(装置) called T-Box that harnesses wind energy from speeding trains.

    T-Box can be placed within the railway tracks. It is half-buried underground between the concrete sleepers(水泥枕木), which does not disturb the normal train operating at all. According to Yanko, around 150T-Boxes can be fitted along a 1,000-meter railway track.

    A train running at a speed of 200 kph can produce winds blowing at 15 miles a second. Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day. The T-Box's design won a silver medal in last year's Lite-On Awards and was exhibited last summer at the Xue Xue Institute inTaipei, Taiwan Province.

    Though the figures look impressive, it is important to remember that the design is still at a conceptual stage and hasn't taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance(维护) of the device.

    We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient.

    Beijing's markets will soon be flooded with more and cheaper colorful fruit such as orange, mangos and green durian（榴莲）all year round.

    Thanks to a new free trade agreement signed last Monday between China and the Association of Southeast Asian Nations（ASEAN），more and more tropical Southeast Asian fruit will enter the country.

    The agreement means that from July 1,2005, China and ASEAN countries will begin to cut tariffs. There are about 7,000 products included in the cuts. As global communication develops, countries are trading more and more goods with each other. When products are sold across national borders, countries put a tax on them. This type of tax is called a tariff. Just like removing an obstacle from the path of these goods, the reduction of tariffs will encourage trade between China and ASEAN countries. It means more products and lower prices.

    The agreement will bring real benefits for Chinese customers, said a Chinese Foreign Ministry spokesman. “In the Beijing markets you will easily find more tropical fruit like durian, which used to very, very, very expensive. Now they will be cheaper.” The current tariff rate on durian is 22 per cent but will fall to zero in 2005.

    In the first 10 months of this year China did US＄84.6 billion of trade with ASEAN countries. Experts believe this may reach US＄100 billion next year. Founded in 1967, ASEAN now includes Indonesia, Malaysia, Singapore, the Philippines, Thailand, Brunei, Viet Nam, Myanmar, Cambodia and Laos.

Chopsticks

    Right now, millions of people are digging into their food with two sticks that have school the test of time as a utensil(烹调用具)for humans. But what's so special about them? {#blank#}1{#/blank#} Personally, I think they teach us the importance of:

    {#blank#}2{#/blank#} 

    If you're ever tried using them, you know that you can't get what you want by just randomly stabbing at the plate. To be able to get what you want, you have to aim for it. There's no way you can pick up everything in one go. Know what you want, and just do it. {#blank#}3{#/blank#} 

    Practice

    Using chopsticks doesn't come naturally. You can't learn to use them by just reading about them. {#blank#}4{#/blank#} It is the same with the real life. You can read as much as you like about all the things you want to do, but it will just amount to dreams and theory if you don't try actually doing it.

    Slowing Down

    {#blank#}5{#/blank#} Why? Because it allows your stomach to tell your brain you're full before you overeat. Eating with chopsticks is a slower process, but that is not necessarily a bad thing. Sometimes we need to slow down and take things one step at a time, so that we have time to think and realize that we don't have to keep charging full speed through life.

A. Aim

B. Motivation

C. What can we learn from them?

D. You have to practice using them

E. Those who eat too fast were less successful at losing weight

F. Sometimes, a little bit of focus makes the difference between failure and success

G. A common health tip is to try to eat with chopsticks when you can

Time Travel

    If you could travel in time, where would you go? Perhaps you would watch an original performance of a Shakespeare's play in Elizabethan England? What about hanging out with Laozi in the Spring and Autumn Period? Or maybe you'd voyage far ahead of the present day to see what the future holds.

    The possibility of time travel is indeed appealing. Stories exploring the subject have been around for hundreds of years. Perhaps the best known example is science fiction novel. The Time Machine, which was written by H.G. Wells and published in 1895 for the first time. It was adapted into at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term "time machine", coined by Wells, is now universally used to refer to a vehicle transporting people into the far future.

    But could time travel actually be possible? Some scientists say yes, in theory. They propose using cracks in time and space called “wormholes”, which could be used as shortcuts to other periods. Einstein's theory of relativity allows time travel in extreme circumstances. And British physicist Stephen Hawking says you could travel into the future with a really fast spaceship going at nearly the speed of light. Though building such a spaceship would of course be no simple task.

    Even if you could travel into the past, there is something called the “grandfather paradox”. It asks what would happen if a time traveler were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born. If the time traveler wasn't born, how would he travel back in time?

    And would you really like to visit the future? In H.G. Wells' book, the main character travels into distant time where he arrives at a beach and is attacked by giant crabs. He then voyages 30 million years into the future where the only living thing is a black object with tentacles(触角).

    If that's what's in store, maybe we are better just living in the present day after all.

    Learning how to face silence in conversation is an important skill, especially when working across cultures.

    In international negotiations, experienced negotiator (谈判者) stay silent and impassive on purpose because that will make others feel uncomfortable and possibly make compromises without having to do anything. Americans especially can't stand silence, so they often are the first to break the silence and sometimes might be at a disadvantage in negotiations.

    So, what's the best response? Set your jaw and wait it out. Don't offer a compromise just because they are not speaking. If you have to say something, ask a direct question, such as "What's your initial reaction to that offer?" Once a silence is getting into 45 seconds you could say, "Let's come back to that in a minute and go on with the next part of our negotiation."

    In presentations, silence can be far more effective than dramatic passion (热情). Before starting, look at the audience and be silent for a moment because that says, "I'm in control. I know what I'm doing. I'm confident."

    A classic example was when Apple co-founder Steve Jobs launched the first iPhone. He introduced with many pauses so that you didn't miss his key points. Because silence makes us nervous, our natural reaction is that we'd better pay attention, there's something going on here.

    Equally, when giving a speech to staff or trainees, pauses count-especially if there are negatives. If you keep talking you're spoon feeding. Give people a moment of silence to get beyond the emotional response and to start thinking consciously and processing.

    Silence can be an inward-focused thoughtful activity or an outward stillness where you give yourself the time to watch and think and listen to the world around you. Having observed the use of silence in Finland and also among the Blackfeet Nation, a North American Indian tribe in northern Montana in the US, we can see benefits far beyond wheeling and dealing.

    Silence can be a very powerful point for understanding ourselves, understanding others, for developing better common understanding and more productive outcomes and that applies to business, politics, education, law, medicine, every area of human life.

    Gentle Wakeup — Sleep & Alarm Clock with Sunrise — iOS/Android

    Every device(仪器)has an alarm function these days. But what does this app have to offer?

    The makers of Gentle Wakeup believe people can wake up w ell. The key is that the app wakes with light rather than sound. It offers a better move out of sleep through a "Sunrise" — a light slowly, gradually becomes brighter, just as the sun does. But the sunrise is only half of the waking process: The light grows for 20 minutes before you are eased out of your sleep by the natural early morning sounds of birdsongs. The makers believe users of the app will never wake up in the same w ay again: "Start getting awake by light and you will never w ant to wake up by sounds again".

    Forest: Stay focused — iOS/Android

    Though phones make life more convenient, many people feel that they are addictive. Forest is a clever intervention(干预)designed to make people understand that there's more to life than phones.

    Here's how it works: you plant a seed in the app and the longer you stay away from the phone, the more it grows. From a seed, it becomes a tree and then a forest at last. The makers say, the "sense of responsibility and achievement will encourage you to stay away from your phone and focus on what's important in life". And Forest has received some good review s from users, who say that's exactly what it does: "It's a phone game that gives you time rather than taking it away."
