Weighing too much can damage your health,and obesity is a growing problem for both kids and adults around the world.Sleep might be one answer to the problem.A new study has found that elementary school students who slept too little were more likely to gain pounds.　

Past studies have shown a link between sleeping less and weighing more,but scientists have had a tough time determining "which came first,the chicken or the egg," says Julie C. Lumeng of the university of Michigan in Ann Arbor.In other words,it hasn't been clear whether kids who weigh too much have trouble sleeping,or whether sleeping less leads to weight gain.Both scenarios (可能出现的情况) seemed equally possible.

To get a better idea of which causes which,Lumeng and her colleagues interviewed the parents of 785 third graders from around the United States.The parents　 answered questions about how well their kids slept that year.Three years later,the parents answered the same questions.By sixth grade ,18percent of kids involved in the study were obese.

The scientists found no relationship between weight and the students' race or gender.It also didn't matter how strict their parents were,or whether they were boys orgirls.Obesity struck all of these groups equally.Instead,sleep seemed to be the key factor.Over the three years of study,the children averaged a healthy 9.5 hours of sleepa night.Some kids,however,slept a lot moreor less than others.

For the sixth graders,every hour of sleep above the 9.5houraverage was linked toa 20 percent lower risk of being obese.Sleep appeared doubly important for the third graders.Every extra hour of sleep they got was linked to a 40 percent drop in obesity.

A. Scientists have found the exact causes of children's obesity.

B. There is always something difficult to understand through theory

C. The cause–effect relationship between weight and sleep isn't clear.

Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible(无可抗拒的)? For one thing, it’s everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking.

Make friends with dainty(讲究的) eaters.

Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in.

See happy movies… and always get the smaller bag of popcorn(爆米花).

According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container.

Eat breakfast.

Nutritionists have gone back and forth（来来回回）about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising.

Divide your food and conquer overeating.

Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you’re eating and of portion size. Researchers advise reallocating（再分配）snack foods into small plastic bags. It sounds simplistic, but it works.

1.Why do people eat too much junk food though it is bad for our health?

A. It’s delicious from chips to candy.

B. It’s easily taken everywhere.

C. Because it’s available here and there.

D. It’s easily bought in fast food restaurants.

B. Nutritionists have the same opinion about how much to eat in the morning.

C. People prefer to snake from a large bucket.

D. If people are watching a tragedy, they eat up to 29% more popcorn.

3.What will he or she do if he or she wants to lose weight?

A. To eat nothing in the morning.

B. To eat breakfast and exercise.

C. To get up early and to go to bed late.

D. To snack from a medium-size bucket.

4.What is the text mainly about the rule(s)?

A. how to eat properly and healthily.

You should always go to a doctor for advice before you begin any type of exercise program. Then, a good pair of running shoes can be helpful as your feet hit the ground. They will help protect your ankles by providing stability to your feet. So it is good idea to visit a specialty(专业) running shoe store. The staff there can suggest shoes which are ideal for your running style.

In order to learn the proper form, you may get some advice from a friend who has been running for some time, or even join a running club. They can provide good tips as well as some support and encouragement for you.
