Parents must focus on a healthy balanced lifestyle for their children instead of focusing on weight or dieting in order to prevent obesity(肥胖)and eating disorder among teenagers, say new guidelines from the American Academy of Pediatrics. The guidelines were developed in response to growing concern about teenagers’ use of unhealthy methods to lose weight.

Quick weight loss methods can cause medical consequences such as unstable heart rate. Also, teenagers who diet in ninth grade are three times more likely than their peers(同龄人)to be over-weight in 12th grade, the researchers said. “Scientific evidence increasingly shows that for teenagers, dieting is bad news,” said lead author Neville Golden, Professor at the Stanford University.

Parents should not encourage dieting, and should avoid “weight talk” such as commenting on their own weight or their children’s weight. Instead parents should help their children develop a healthy body image by encouraging them to eat a balanced diet and exercise for fitness, not weight loss, the researchers states. Further, they should also never tease teenagers about their weight. Negative comments about weight can also be detrimental to a teenager’s health.

“Mothers who talk about their own bodies and weights can encourage their kids to have body dissatisfaction, which we see in half of teenage girls and a quarter of boys,” Golden noted. Such dissatisfaction is associated with lower levels of physical activities and with use of laxatives(泻药)to control weight.

Families should eat regular meals together, the researchers suggested, adding that eating family meals is likely to prevent weight problems, said the paper published online in the journal Pediatrics. Eating too fast, eating when not hungry, always eating dessert, eating out often are not advisable when you watch your weight.

There is no doubt that many parents want to mold (塑造)their child to be better, faster, smarter and more skilled. Even though human parents can’t do that, a robot that builds its own children can. Scientists at the University of Cambridge in England have created a mother robot that not only creates its own children, but tests out their performance.

The mother robot analyzes(分析)the performance of each of the “children” it creates, and passes down good characters to the next generation

For example, as the mother creates them and puts them to work, she measures how they’re behaving, and she uses data from this behavior to create the next generation of robots.

The mother robot can actually build hundreds of child robots and see the performance of these child robots. And if their performance is good, keep their design for the next generation. And if bad, just let it go.

“We program the robots based on some functions that define(规定)the reward the robots are going to get, depending on the construction that they make. They cannot change their own reward. For the child robot, the longer the distance the robot walks, the better the reward it receives,” said Fumiya Iida, the lead researcher.

After several generations, the “children” were running twice as fast.

“The mother robot produced 500 robots to see which one is good and which one is bad,” said Iida.

The researchers believe that the machines can be used in a car factory, for example, where robot cameras examine each ear in production line, find out any mistakes, and then design a better car.

1.What is special about the mother robot?

A. It can analyze data

B. It can create child robots

C. It’s smarter than human mothers

D. It can build and improve its own children.

2.How does the mother robot mold her own children to be better?

A. It teachers them how to behave better.

B. It reprograms the bad ones after analyzing their performance

C. It copies hundreds of child robots and then chooses the best ones.

D. It keeps the good characters for the next generation to create a better robot.

3.What is the key point in influencing the child robot to receive a reward?

A. Size B. Distance.

C. Behavior D. Speed.
