Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.

How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.

“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can manfen5 get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.

Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.

Roller coasters are fast and exciting. But passing a painful kidney (肾) stones is not. The process is painful and can take a long time. But American researchers have found that a roller coaster ride just might help those suffering from a kidney stone. They say such rides help patients pass the stones with a 70 percent success rate.

David Wartinger led the study. He found that where the person sits on the roller coaster can make a big difference. He said, “In the pilot study, sitting in the last car of the roller coaster showed about a 64 percent passage rate. Sitting in the first few cars only had a 16 percent success rate.”

It also mattered where the stones were located in the kidney. The researchers found that stones located in the upper part of the kidney model were passed 100 percent.

When it comes to passing kidney stones, not all roller coasters are equal. The researchers used 174 kidney stones of differing shapes, sizes and weights to see if each model worked on the same ride and on two other roller coasters. They found that Big Thunder Mountain was the only one that worked. The other two roller coasters both failed the test. Wartinger said the other rides were too fast and too violent. The movement forced the stones against the side of the kidney. He said that the ideal roller coaster is rough and quick with some twists and turns.

Wartinger thinks roller coaster rides could also be used as a preventative measure. He said that a yearly ride on a roller coaster could even prevent stones from developing. “You need to heed the warnings before going on a roller coaster,” he said. “If you have a kidney stone, but are otherwise healthy and meet the requirements of the ride, patients should try it.”

He adds that it’s definitely a lower cost alternative to other treatments. And riding a roller coaster is definitely more fun!

It’s said that one can know the nature of both man and woman by their behaviors at table. Indeed table manners are closely related to one’s life and one’s job. As the saying goes “When in Rome, do as the Romans do”, English learners should know what the proper table manners are in western countries if invited to a dinner party. The followings are some suggestions that may be helpful to you.

The first important thing you need to know is when to begin eating. Before dinner, the hostess usually serves guests first and herself last. So do not eat as soon as you are served but wait until the hostess has also been served and has picked up her fork as the signal to begin. But at a large dinner party where there are many guests, the hostess may ask everyone to begin eating as soon as they are served.

If you want to talk while eating, your mouth should certainly not be full of food because it is considered very bad manners. But it is possible to speak with a little food in the mouth. When you have to answer a question, naturally you must wait until the food in your mouth is eaten.

When a dish is passed to you with a fork in the plate, you should use it to take your food. Do not take too much at a time and make sure that the other guests can have enough food.

Anyway, good table manners are very important and they are not so simple as we thought. But it is necessary for one to know what good table manners are because they can help one succeed in his life!
