TOKYO —Imagine a bicycle seat connected by mechanical frames(機械支架) 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(腳底) to help lift my legs when I walked,” he said.

         The system has a computer, a motor, gears（齒輪）, 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．

68．Honda's new wearable assisted-walking machine is mainly to      .

         A．show Honda's power in technology  B．protect the environment                        

         C．meet the social needs in the future  D．improve social progress

         A．manpower                       B．batteries

         C．a computer                    D．the machine movement

70．It can be learned from the passage that              .

         A．the new machine has been produced m large numbers

         B．Honda will control the future market for the new machine

         C．the price of Honda's new machine will be very low

         D．the future market for the new machine will be promising

71．What would be the best title for the passage?

         A．Wearable machine that helps walk

         B．Hondo's new bicycle for the old

         D．New development of the bicycle

Remind children that bad things don’t last. It may sound simple, but the message is extremely important. “Children often don’t have the experience to know that when something bad happens—they lose an important game or their best friends lets them down—it’s not the end of the world,” explains Nancy Leffert, a senior research scientist with the Research Institute, an American adolescents’(青少年) and children’s research group. “They think their bad feelings will last for ever， or that one failure will ruin everything.”

Unfortunately, that kind of thinking discourages motivation(動機).“If a child believes that the cause of her upset is lasting, or that nothing she does will make a difference, it decreases her ability to keep on trying,” says Dorothy Rich, president of the Mega Skills Education Center of the Home and School Institute, based in Washington. Any time you can help your child see that a situation is not lasting, that a result can be changed, or that one opinion does not reflect reality, you give her reason to hope.

Case in point: “When my daughter Kathy was eight，art was one of her favorite subjects，”says Beth，a mother of two. “Then she got an art teacher who gave a great deal of praise to one student and barely noticed the rest．Kathy was ready to give up until I explained to her，‘Never stop doing your best just because one person doesn’t give you praise.’” Beth had to repeat the advice often，and finally her daughter got the message．“Kathy is twelve now, and art is still one of her strongest subjects.”
