TOKYO —Imagine a bicycle seat connected by mechanical frames(机械支架) to a pair of shoes for an idea of how the new wearable assisted-walking machine from Honda works．

The experimental machine, showed on Friday, is designed to support bodyweight, reduce stress on the knees and help people organize steps and stay in crouching（蹲坐） positions．Honda showed a video of its employees wearing the machine.

Engineer Jun Ashihara also said the machine is useful for people standing in long lines and to people who run around to make deliveries．

"This should be as easy to use as a bicycle," Ashihara said．"It reduces stress, and you should feel less tired．"

To wear it, you put the seat between your legs, put on the shoes and push the “on” button．Then just start walking around．

In a test run for media, this reporter found it does take some time to get used to the machine.  “I could sense how it supported my moves, pushing up on my bottom when I crouched and pushing at my soles(脚底) to help lift my legs when I walked,” he said.

The system has a computer, a motor, gears（齿轮）, batteries and sensors in it, so it responds to a person's movements, according to Honda Motor Co．

Pricing and commercial product plans are still undecided．Japan's No．2 automaker will begin testing a prototype（模型） later this month．

The need for such mechanical help is expected to grow in Japan, which has one of the most rapidly aging societies in the world．

Other companies are also eyeing the potentially attractive market of helping the weak and the old get around．Japan is among the world's leading nations in robotics technology, not only for industrial use but also for entertainment and companionship．

To get an extra 14 years of life, don’t smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount．That is according to a study published this Monday in the Public Library of Science Medicine Journal．

After tracking more than 20,000 people aged 45-79 years in the United Kingdom from about 1993-2007, Kay-Tee, Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived an average of 14 years longer than those who didn’t．

“We’ve known for a long time that these behaviors are good things to do, but we’ve not seen this benefit before, ” said Susan Jebb, head of Nutrition and Health at Britain’s Medical Research Council．“The benefit was also seen regardless of whether or not people were fat and what social class they came from．”

Study participants(参与者) scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．

Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes．But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviours would surely gain 14 years．

“We can’t say that any person could gain 14 years by doing these things,” said Doctor Tim Armstrong, a physical activity expert at the World Health Organization．”The 14 years is an average across the population of what’s theoretically(理论上) possible．”

“Most people know that things like a good diet matter and that smoking is not good for them”, Susan Jebb said, ”We need to work on providing people with much more practical support to help them change．”

1．Which of the following doesn’t belong to the four healthy habits?

A．Eating five servings of fruits and vegetables a day．

B．Doing proper exercise in the morning every day．

C．Having a cigarette before going to bed every day．

D．Drinking alcohol in the proper amount every day．

2．We can learn from the passage that_____．

A．the study observed people as well as tested specific changes

B．Susan Jebb did not take part in the study

C．there is no need for people under 45 adopt these good habits

D．only those from first class can benefit from these healthy behaviours

3．What can be inferred from the passage?

A．Governments should take measures to help people change their bad habits．

B．People aged 45-79 have bad habits in the United Kingdom．

C．All the people are well aware of the harm of their bad habits．

D．People have adopted the four healthy habits after knowing they’re good．

4．What would be the best title for this passage?

A．Smoking and Drinking Cuts You 14 Years

B．Healthy Habits Could Gain You Extra 14 years

C．A New Way of Keeping Healthy

D．Smoking and Drinking Harms Your Health
