If eighteen-year-old Karki doesn't turn out to be the next Edison, I'll chop off my locks This kid invented a solar pane (嵌板) which uses human hair as a conductor and could provide the world with cheap, green electricity, solving the energy crisis.
Karki, a Nepal teenager, who lives in a village in Rural Nepal, used human hair to replace silicon, which is a common but expensive component of solar panels.
By using hair as a replacement, Karki says solar panels can be produced for around 23 pounds. But if they were mass-produced, Karki says they could be sold for less than half that price, which could make them a quarter of the price of those already on the market.
The solar panel works because melanin, the substance giving hair its color, is light sensitive and can act as an electrical conductor. Karki was inspired to follow this route by a Stephen Hawking book, which explained how to create energy from hair.
The device (设备) Karki has shown is able to produce 9V or 18W of energy -- plenty to charge a mobile phone. Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months, where as a pack of batteries would cost 50p and last a few nights," according to Karki.
Karki has now sent out several devices to other districts near his village for testing. "First I wanted to provide electricity for my home, then my village. Now I am thinking for the world," he said.
Karki says the idea is more important than ever because of the urgent need for renewable energies in the face of limited power sources and global warming. Slowly, natural resources are decreasing. One day we will be in a great crisis. This is an easy solution for the crisis we are having today.

Many English learners have difficulty deciding what kind of English accent they want to have． A US accent, perhaps modeled on the way a Hollywood star speaks? Or maybe you want to imitate（模仿） the British accent of a BBC news reader?
Young British people find the US accent attractive while young US people like a British accent． Especially when the person speaking is of the opposite sex(异性)! Let’s listen to what they have to say．
Stephen Yang, 17, from London, UK
A US accent is cute, especially when a girl speaks it． Whether it’s Jessia Alba speaking or the girl- next-door, the way US girls speak has a sweet tingle that is really sassy(时髦)． A girl from Texas recently moved into our neighborhood． Her Texan twang（鼻音） had all the boys here on their knees within seconds of meeting her．
To me, accents reflect the attitudes, characteristics and lifestyles of the people．

Shopping is not as simple as you may think! There are all sorts of tricks at play each time we reach out for that particular brand(品牌) of product on the shelf.
Colouring, for example, varies according to what the producers are trying to sell. Health foods are packaged(包装) in greens, yellows or browns because we think of these as healthy colours. Ice cream packets are often blue and expensive goods, like chocolates, are gold or silver.
When some kind of pain killer was brought out recently, researchers found that the colours turned the customers off because they made the product look weak and ineffective. Eventually, it came on the market in a dark blue and white package—blue because we think of it as safe, and white as calm.
The size of a product can attract a shopper. But quite often a bottle doesn’t contain as much as it appears to.
It is believed that the better-known companies spend, on average, 70 percent of the total cost of the product itself on packaging!
The most successful producers know that it’s not enough to have a good product. The founder of Pears soap, who for 25 years has used pretty little girls to promote (推销) their goods, came to the conclusion: “Any fool can make soap, but it takes a genius(天才) to sell it.”Which of the following may trick a shopper into buying a product according to the text?
