3 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

The Meredith family lived in a small community. As the economy was in decline, some people in the town had lost their jobs. Many of their families were struggling to make ends meet. People were trying to help each other meet the challenges.

Mrs. Meredith was a most kind and thoughtful woman. She spent a great deal of time visiting the poor. She knew they had problems, and they needed all kinds of help. When she had time, she would bring food and medicine to them.

One morning she told her children about a family she had visited the day before. There was a man sick in bed, his wife, who took care of him and could not go out to work, and their little boy. The little boy -his name was Bernard-had interested her very much.

“I wish you could see him,” she said to her own children, John, Harry, and Clara. “He is such a help to his mother. He wants very much to earn some money, but I don't see what he can do.”

After their mother left the room, the children sat thinking about Bernard. “I wish we could help him to earn money,” said Clara. “His family is suffering so much.”

“So do I,” said Harry. “We really should do something to assist them.”

For some moments, John said nothing, but, suddenly, he sprang to his feet and cried, “I have a great idea! I have a solution that we can all help accomplish(完成).”

The other children also jumped up all attention. When John had an idea, it was sure to be a good one. “I tell you what we can do,” said John. “You know that big box of corn Uncle John sent us? Well, we can make popcorn(爆米花), and put it into paper bags, and Bernard can take it around to the houses and sell it.”

In ancient China lived an artist    1     paintings were almost lifelike. The artist’s reputation had made him proud.

The artist was sure he would    3    (choose), but when he presented his masterpiece to the emperor’s chief minister, the old man laughed. The wise old man told him to travel to the Li River～perhaps he could learn a little from the greatest artist in the world.

Filled with     4     (curious), the artist packed his bags and left.     5     he asked the villagers on the banks of the river where he could find the legendary (传奇的) artist, they smiled and     6     (point) down the river. The next morning he hired a boat and set out     7     (find) the well-known painter. As the small boat moved,     8     (gentle) along the river he was left speechless by the mountains being silently reflected in the water. He passed milky white waterfalls and mountains in many shades of blue. And when he saw the mists rising from the river and the soft clouds    9     (surround) the mountain tops, he was reduced to tears. The artist was finally humbled (谦卑) by the greatest artist     10     earth, Mother Nature.

A 90-year-old has been awarded “Woman Of The Year” for     1    (be) Britain’s oldest full-time employee—still working 40 hours a week. Now Irene Astbury works from 9am to 5pm daily at the pet shop in Macclesfield,     2     she opened with her late husband Les. Her years of hard work have     3    (final) been acknowledged after a customer nominated(提名) her to be Cheshire’s Woman Of The Year.

Picking up her “Lifetime Achievement” award, proud Irene     4    (declare) she had no plans     5    (retire) from her 36-year-old business. Irene said, “I don’t see any reason to give up work. I love coming here and seeing my family and all the friends I     6    (make) over the years. I work not because I have to,     7     because I want to.”

Granddaughter Gayle Parks, 31—who works alongside her in the family business—said it remained unknown as to who nominated Irene for the award. She said, “We don’t have any idea who put grandma forward. When we got a call     8    (say) she was short-listed, we thought it was     9     joke. But then we got an official letter and we were blown away. We are so proud of her. It’s     10    (wonder).”

10 . As data and identity theft becomes more and more common, the market is growing for biometric(生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.

Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.

It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.

In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.

1. Why do the researchers develop the smart keyboard?

A．To reduce pressure on keys.	B．To improve accuracy in typing.
C．To replace the password system.	D．To cut the cost of e-space protection.

2. What makes the invention of the smart keyboard possible?

A．Computers are much easier to operate.

B．Fingerprint scanning techniques develop fast.

C．Typing patterns vary from person to person.

D．Data security measures are guaranteed.

3. What do the researchers expect of the smart keyboard?

A．It’ll be environment-friendly.	B．It’ll reach consumers soon.
C．It’ll be made of plastics.	D．It’ll help speed up typing.

4. Where is this text most likely from?

A．A diary.

B．A guidebook

C．A novel.
