1 . Bitcoin and other so-called cryptocurrencies （加密货币）have been all over the news lately. Apparently, the idea of money that's not tied to a specific bank—or a specific country—is appealing to many. But it's worth remembering that the banking system that we now all live with is just that： A modern invention. Not so long ago, money was almost always created and used locally, and bartering was common. （In fact, it still is common among many online local networks, like the Buy Nothing Project.）.
In the past, money's makeup varied from place to place, depending on what was considered valuable there. So while some of the world's first coins were made from a naturally occurring hybrid of gold and silver called electrum （银金矿），objects other than coins have served as currency, including beads, ivory, livestock, and cowrie shells. In West Africa, bracelets of bronze or copper were used as cash, especially if the transaction was associated with the slave trade there. Throughout the colonial period, tobacco was used to replace coins or paper bills in Virginia, Maryland and North Carolina, even though it was used elsewhere in the colonies and extensively throughout Europe and the U. K.
Today, on an island in the Pacific, a specific type of shell still serves as currency—and some people there are even hoarding（贮存）it, just like Bitcoin moguls, convinced that one day, it will make them wealthy beyond imagination. On Malaita, the most-populated island that's part of the Solomon Islands, shells are accepted at most places in exchange for goods.
"How much tuna（金枪鱼）you can get for your shells depends on their color and shape," Mary Bruno, a shop owner from the small town of Auki, on Malaita, told Vice. "One strip of darker shells might get you about two cans of smaller tuna, but the red ones are worth more. For the red ones, one strip might get enough tuna to feed a big family for a long time."
Just like a mint that creates coins, there's only one place on the island where the shells, which are polished and strung together to form 3-foot-long ropes, are made. The strips of red, white, and black shells all come from Langa Langa Lagoon, where artificial islands were long-ago built by locals to escape from the island-dwelling cannibals. Once marooned（困住）out on their islands, locals needed a currency to use among themselves, and so the shell currency was born.
Using shells for money was common throughout the Pacific islands as late as the early 1900s, but Malaita is unique in that they are still used today. And just like cryptocurrencies, there are those who think the islanders are smart to invest in this type of money, which is reported to have risen in value over the last three decades. It might seem strange to hoard a bunch of processed, strung-together shells, but what is a pile of dollars? Just a specially printed piece of paper and hemp that we've assigned value to—and probably less durable over time than those shells.

The set-up is relatively simple. Both users wear a virtual reality headset with a camera on the top. The video from each camera is sent to the other person, so what you see is the exact view of your partner. If she moves her arm, you see it. If you move your arm, she sees it.
To get used to seeing another person's body without actually having control of it, participants start by raising their arms and legs very slowly, so that the other can follow along. Eventually, this kind of slow synchronised（同步的）movement becomes comfortable, and participants really start to feel as though they are living in another person's body.
Using such technology promises to alter people's behaviour afterwards-potentially for the better. Studies have shown that virtual reality can be effective in fighting racism-the bias（偏见）that humans have against those who don't look or sound like them. Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test, which measures the strength of people's associations between, for instance, black people and adjectives such as good, bad, athletic or awkward. Then they asked them to control the body of a dark skinned digital character using virtual reality glasses, before taking the test again. This time, the participants' bias scores were lower. The idea is that once you've "put yourself in another's shoes" you're less likely to think ill of them, because your brain has internalised the feeling of being that person.
The creators of The Machine to Be Another hope to achieve a similar result. "At the end of body swapping, people feel like holding each other in their arms," says Arthur Pointeau, a programmer with the project. "It's a really nice way to have this kind of experience. I would really, really recommend it to everyone."

 |  The Curse of the Were-Rabbit(2005) is the first full-length feature film made by directors Nick Park and Steve Box with their amazing plasticine(粘土) characters Wallace and Gromit. It won an Oscar in 2006, and if you watch it, you’ll understand why. It’s an absolutely brilliant cartoon comedy. |
| Cheese-loving inventor Wallace and his brainy dog Gromit have started a company to protect the town’s vegetables from hungry rabbits. However, just before the annual Giant Vegetable Competition, an enormous rabbit begins terrorising the town. It is attacking all the vegetables and destroying everything in its path. The competition organizer, Lady Tottington, hires Wallace and Gromit to catch the monster alive. But they will have to find the were-rabbit before gun-crazy hunter Victor Quartermaine who is desperate to kill it. | |
| The screenplay is witty and full of amusing visual jokes. As usual, the voice of Peter Sallis is absolutely perfect for the role of Wallace, and Gromit is so beautifully brought to life, he can express a huge range of emotions without saying a word. And both Helena Bonham-Carter, who plays the part of Lady Tottington, and Ralph Fiennes as Victor are really funny. | |
| To sum up, The Curse of the Were-Rabbit is an amazing film which is suitable for both children and adults. If you liked Wallace and Gromit’s previous adventures and you appreciate the British sense of humour, you’ll love this film. Don’t miss it! |
