Snack time is a part of the day for children of all ages. But new research suggests that kids snacking in big groups could be at risk for obesity.
Scientists from American University looked at the eating behavior of 54 kids between the ages of 2 and 6. At snack time, the scientist watched the amount of food each child ate while they were in groups of either three or nine. According to the study, the more children there are in a group, the more likely they are to eat more. Those in the larger group ate nearly 30 percent more than those in the smaller group, and they actually ate faster.
Since this is the first such study in children, scientists are quick to point out the importance of encouraging healthy habits in kids as early as possible.
“If you know kids eat more in large groups, it seems perfect to use this information to keep snack groups small or use small tables,” says Dr. Jana Klauer, an expert in New York.
Smaller groups would allow for a quiet and more relaxing environment-a perfect chance to teach children about food, manners and how to know when they feel full. “This would have an effect on kids' eating,” adds Klauer. “They would slow down and eat less.”

How important is homework? According to the Los Angeles Unified School District(LAUSD), it’s not that important! The district has made a big change for the 2011-2012 school year. It started on July 1, homework counts for only 10% of a student’s grade. The district, the second largest in the country, says its new way can provide a fairer assessment(评定) of students’ homework and achievements.
The district hopes students only need to spend less time on homework and more time on hobbies and with their families. By reducing the weight of homework toward a student’s grade, a truer picture of the student’s knowledge will be shown in the achievement grade.
However, it doesn’t mean the students can throw out homework. It says that homework is a chance for students to practice their skills and a tool for students to prepare for coming lessons. Still, LAUSD is joining a growing list of schools that have controlled the amount of homework.
How much time children should spend on homework is a hot topic. Harris Cooper, a professor at a university, says that the proper amount of homework time is ten minutes a day multiplied by(乘以) the student’s grade. This means a third grader should spend 30 minutes a day on homework. And a sixth grader would spend 60 minutes. “Good homework in the proper amount will have better effects on them,” he said. “Bad homework or too much homework will have worse effects.”
But some people think homework is an important part of learning. They say many children just won’t try their best if homework doesn’t count toward their grade. Some teachers also think homework is important. They argue that students who do their homework perform better on tests and in school than those who do not. They are afraid that the new way will encourage students to pay less attention to homework.

The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?
The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.
The energy in food is in the form of three kinds of chemical materials—carbohydrate(碳水化合物), protein(蛋白质) and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.
(P= protein C= carbohydrate F=fat)
