【题目】Growing up in Philadelphia, Lieberman started cooking with his stay-at-home dad when he was seven.His food-loving family had two kitchens, and he quickly learned what was the best way to bake his cakes.Lieberman improved his kitchen skills greatly during a year abroad before college, learning from a cook in Italy and studying local specialties(地方特色菜)in Germany, Spain and France.At Yale, he was known for throwing dinner parties, single-handedly frying and baking while mixing drinks for dozens of friends.Just for fun, he and some friends decided to tape a show named Campus Cuisine about his cooking.Lieberman was a real college student showing his classmates how to do things like make drinks out of dining-hall fruit.That helped the show become very popular among the students.They would stop Lieberman after classes to ask for his advice on cooking.Tapes of the show were passed around, with which his name went beyond the school and finally to the Food Network.

Food Network producer Flay hopes the young cook will find a place on the network television.He says Lieberman’s charisma is key.“Food TV isn’t about food anymore,” says Flay.“It’s about your personality(个性)and finding a way to keep people’s eyeballs on your show.”

But Lieberman isn’t putting all his eggs in one basket.After taping the first season of the new show, Lieberman was back in his own small kitchen preparing sandwiches.An airline company(航空公司)was looking for someone to come up with a tasteful, inexpensive and easy-to-make menu to serve on its flights, Lieberman got the job.

【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.

【1】What’s the main idea of the passage?

A. How to reduce energy whiling walking.

B. Ways to make walking easy.

C. Introduction to a mechanical device to make walk easier

D. Guidelines for people recovering from surgery.

2What is true according to the passage ?

A.The device can only benefit people with walking problems.

B. All people could benefit from it.

C. With the device, the walkers need seven percent as much as the energy otherwise.

D. The device can benefit people in the long term.

3What does the underlined word propel” mean in paragraph 3?

A. put B. keep C.help D. push

【4】What can we learn from the last paragraph?

A. The ankle exoskeleton will have a bright future.

B. The ankle exoskeleton hasnt appeal to manufacturers.

C. The ankle exoskeleton will be launched in the market soon.

D. The ankle exoskeleton will never be produced.
