【题目】C

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 that intermittently 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, works a lot like a catapult. 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 propel 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 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 surgery 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.

【题目】Isabella Stewart was born in New York City in 1840. Her father made a great deal of money in trade. During school,her parents took her to Italy to explore the country's many cultural treasures.

One of the private art collections Isabella visited in Milan had a deep influence on her. She wrote to her friends about her dream of owning a house one day with an art collection like the one she had seen in Italy.

In Paris, Isabella became a close friend of one of her classmates, Julia Gardner, whose family was from Boston. Julia would later introduce Isabella to her brother, Jack. In 1860, Isabella Stewart married Jack Gardner.

The couple had too much art to fit inside their home. So they decided to start planning a museum. Mrs. Gardner didn't like the cold and empty spaces of many museums during her time. She wanted a warm museum filled with light. She once said that she decided years ago that the greatest need in her country was art. America was a young country developing quickly in other areas. But the country needed more chances for people to see beautiful examples of art.

After her husband's death in 1898, Isabella knew she had no time to lose in building her museum. She bought land, hired a building designer, and supervised (监督)every detail of her museum's construction.

Mrs. Gardner opened her museum on January 1,1903. The museum was then called Fenway Court. She invited her friends that night for a special musical performance. The next month, she opened the museum to the public. At first, visits were limited to twenty days out of the year. Visitors paid one dollar to enter.
