Devices that help people walk were once thought to be impossible to design without some kind of auxiliary power. But U.S. scientists at Carnegie Mellon University and the University of North Carolina have built a small, wearable addition to ordinary shoes that reduces the burden on the calf muscle and makes walking easier.

Burning less calories while walking seems like a bad idea, but making the walk easier may

actually keep people on their feet longer, and that scientists say, has substantial health benefits.

Analyzing the human walk, biomedical engineers Steven Collins and Greg Sawicki concluded that our ankles and calves perform motions similar to a spring coupled with a clutch(离合器) that stores and releases energy.

Sawicki, from the University of North Carolina, explained what’s involved.

“We found in basic science experiments that that system, your calf and Achilles tendon (跟腱), works a lot like a catapult (弹弓). So, the muscle holds on to the tendon and your body actually stretches your Achilles tendon quite a bit and then stores the energy in the tissue and then it’s given back to push you forward in the world,” he said.

Sawicki said he and his colleague Steven Collins at Carnegie Mellon University designed a mechanical device, made of carbon fiber and metal, that performs the same sequence of energy give-and-take outside the body. The system takes over part of the work of walking, and reduces the amount of required energy by as much as seven percent.

Wearing the unpowered ankle exoskeleton(外骨) can help people either walk farther with the same amount of energy, or restore the normal movement pattern for people who have trouble walking.

Sawicki said it takes only a few minutes to get used to the exoskeleton but the wearer quickly learns to tone down the muscle energy as the device takes over part of the load.

“You really don’t notice it until when you take it off. And when you take it off you realize that it was there and giving you the boost,” he said.

Sawicki added that the device is primarily intended for people recovering from an operation or a stroke. But all persons who spend a lot of time walking, such as police officers or hospital personnel, could benefit from it.

At the moment there are no plans to develop the ankle exoskeleton for the market, but the inventors say some manufacturers have expressed interest. 63. When we walk, Achilles tendon _______ . A. stores energy

B. holds our muscle D. looks like a catapult

C. stretches our calf

Jeff Bezos was born on January 12, 1964, in Albuquerque, New Mexico. Bezos had an early love of computers and studied computer science and electrical engineering at Princeton University. After graduation, he worked on Wall Street, and in 1990 became the youngest senior vice president at the investment firm D.E. Shaw. Four years later, he quit his well-paid job to open Amazon. com, a virtual bookstore that became one of the internet's biggest success stories. In 2013, Bezos made headlines when he purchased The Washington Post in a $250 million deal.

Bezos set up the office for his new company in his garage where, along with a few employees, he began developing software. They expanded operations into a two-bedroom house, equipped with three Sun Microstations, and eventually developed a test site. After inviting 300 friends to beta test the site, Bezos opened Amazon. com, named after the South American River, on July 16, 1995.

The company achieved instant success. With no press promotion, Amazon. com sold books across the United States and in 45 foreign countries within 30 days. In two months, sales reached $20, 000 a week, growing faster than Bezos and his start-up team had expected.

Amazon. com went public in 1997 and many market analysts questioned whether the company could hold its own when traditional retailers(零售商）launched their own e-commerce sites. Two years later, the start-up not only kept up, but also outpaced(超越）competitors,

becoming an e-commerce leader.

Bezos continued to diversify Amazon's offerings with the sale of CDs and videos in 1998, and later clothes, electronics, toys and more through major retail partnerships. While many dot.coms of the early '90s closed down, Amazon was successful with yearly sales that jumped from $510,000 in 1995 to over $ 17 billion in 2011.

In 2007, Amazon. com released(发布) the Kindle, a handheld digital book reader that allows users to buy, download, read and store their book selections. That same year, Bezos also set his sights far, far, away, announcing his investment in Blue Origin, a Seattle-based aerospace company that is developing technologies to offer space travel to paying customers.

Bezos then moved Amazon into the table marketplace with the release of the Kindle Fire in 2011. The following September, he announced the new Kindle Fire HD, the company's next generation tablet at a certain price. We have built the best table at any price,\Bezos said, according to ABC News.

Bezos made headlines worldwide on August 5 , 2013, when he purchased The Washington Post and other publications connected with The Washington Post Co., which owns the paper and other entitles, for $250 million cash. The deal marks the end of the four-generation reign over The Post Co. by the Graham family.

In the early December 2013, Bezos made headlines when he released a new, experimental initiative by Amazon, called\can perform a series of human tasks- to provide delivery services to customers. According to Bezos, these drones are able to carry items weighing up to 5 pounds, and are capable of travelling within a 10-mile distance of the company's distribution center. He also stated that Prime Air could become a reality within as little as four or five years.
