Simply increasing physical activity levels alone is unlikely to reduce body weight in young children, and therefore will probably not prevent obesity (肥胖), although it may set the stage for a healthier lifestyle, the results of a study conducted in Scotland suggest.

Instead, a combination of increased physical activity and other lifestyle changes like sticking to a healthy diet may be needed to stop the trend of obesity.

  “Many children are obese, even at preschool age,” Dr John J. Reilly from the University of Glasgow and his colleagues note in the British Medical Journal. Considering the general lack of evidence on proper ways to prevent obesity in this age group, Reilly’s team had 545 children from 36 nursery schools in the “Movement and Activity Glasgow Intervention (干预) in Children” or MAGIC trial.

The trial was specifically designed to see if an increase in activity could reduce body mass index (身体质量指数). Each week for 24 weeks roughly half of the preschoolers, who were an average of 4.2 years old, participated in three 30-minute active workouts while at nursery school and their parents were encouraged to increase the child’s activity levels at home. The other half of

the children, serving as contrasts, followed their usual nursery school schedule.

      According to the researchers, the physical activity intervention had no significant effect on body mass index of the children.

      However, compared with contrast children, intervention children show greater gains in body movement skills, which, the researchers say, may increase confidence in physical ability, perhaps increasing the opportunities of future participation in physical activity or sports.

      In a word, Reilly and his colleagues suggest that “successful interventions to prevent obesity in early childhood may require changes not just at nursery, school, and home, but in the wider environment. Changes in other behaviors, including diet, may also be necessary.”

What’s wrong with the student’s answer? He didn’t accept the compliment in____same way as the American people do．He should say“Thank you”instead of“No”．He _____(real) understood what the American boy had said，____he thought he should be modest．In the west，people will feel proud and confident when they____(praise)．So if someone says the dishes you have cooked are very delicious，you should say“Thank you”．If someone says to a woman“You look so____(beauty)with the new clothes on”，she must be very happy and say“Thank you”．

If you are modest and say“No，I'm afraid I can’t do it well”while _____(work)in a western country，the others may think that you really cannot do it．If you often say“No”，you will certainly be looked down upon by others．If asking_____a job，one says something like“Yes，I can certainly do it” instead of Let me have a try he or she will hope ____(get)it. So in the west，you should be brave to show your_____(confident)!

“Image is everything．” An entire industry has been built upon the assumption that image is everything, but when it comes down to it, an appealing image is not enough．If there is no substance（事实） behind the image, the product, service or person will fail eventually．

First of all, one should consider how important image is in the selling of products and services．Advertising agencies have raised the art of creating an image to a state of near perfection．Public concept of that product or service is certainly managed by the images created by the advertising agencies．But if the product or service does not live up to the image that was created, the customer will be very dissatisfied and possibly ask for their money back．For example, the Arthur Andersen accounting firm had spent decades building up an image of trustworthiness．But the recent scandal（丑闻）showed that behind that image, it cheated in business practices．Despite the previous positive image, the firm is being accused of criminal actions and it will probably not survive as a business unit．Although the image had been nearly perfect, the reality behind the image has led to the downfall of the world famous accounting firm．

Similarly, personal advisers can build up a public image for politicians and movie stars．Putting out positive news releases, making sure that only the best photographs are published, and ensuring that the person is seen in all the right places can build up a very positive image in the view of the general commons．But once again, history is filled with examples of both politicians and movie stars that fell from grace like the story of the Hollywood actor giving in to the pressures of fame and fortune．With people, just as with products and services, image is certainly important, but without positive substance behind the image, failure is close．

To summarize, it is clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling” of a person．But image is only half of the equation．What lies behind that image is every bit as important as the image itself —— the person or product must deliver on that image or there is little chance for long-term success．
