A study finds that not enough morning light causes teenagers not to get enough sleep at night. “As teenagers spend more time indoors, they miss necessary morning light. Day light is needed to keep the balance of the body’s 24-hour biological system (生物系统), which regulates (调节) body temperature and sleep styles,” reports Dr. Mariana Figueiro. “These teenagers who receive little morning light are going to bed later, getting less sleep and doing badly in tests. They are more likely to fail in their exams.”
In the study, Dr. Figueiro asked 11 students in Grade 8 to wear special glasses to prevent blue morning light from reaching their eyes. At the end of the 5-day study she found that they fell asleep 30 minutes later than usual.
Throughout her research, Dr. Figueiro has been very worried about teenagers going to bed too late. The problem is that today’s schools require teenagers to be in school very early in the morning. These students are likely to miss the morning light because they often go to school before the sun is up or as it’s just rising.
Furthermore (此外), the schools are not likely to provide enough electric light to keep the balance of this biological system. Our biological system is much more sensitive (敏感的) to blue light. Therefore, having lots of light in the classroom does not make sure that there is enough light to keep our biological system balanced.

A girl complained to her father about her hard life.She didn't know what she had to do and wanted to give up.She felt tired of fighting and fighting.One problem had been finished but another came over.
Her father，a cook，took her into the kitchen.He poured water into three pans and boiled(煮沸) them.After boiling，in the first pan was put some carrots，the second was put some eggs and the last was put with coffee.
The girl waited impatiently (不耐烦的)，confused by what her father did.About 20 minutes later，her father took out the carrots and put them in a bowl.He took the eggs and put them in a bowl.After that the coffee was poured into a cup.“My sweet heart，what do you see？” he asked.
“Carrots，eggs and coffee，” she replied.
Her father told her to close her eyes and asked her to touch the carrots.She did so and felt that the carrots were soft.After that he asked her to take the eggs and break them.After peeling (剥开) them，she got the eggs，cooked and hard.The last，the father let her smell the coffee. She asked，“What did you do this for，Father？” He explained that each had the same unlucky experience—the boiling water，but each had a different result. The strong and hard carrots had become soft and weak.The fragile eggs became hard after being cooked. The coffee was very special，they could change water.“Who are you？” asked her father.“When bad luck knocks at your door，what is your decision? Are you carrots，eggs or coffee？”
