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 Trap
Mr. Smith left his car outside his apartment one night as usual, but when he came down the next morning to go to his office, he discovered that the car wasn’t there. He called the police and told them what had happened, and they said that they would try to find the car.
When Mr. Smith came home from his office that evening, the car was back again in its usual place in front of his house. He examined it carefully to see whether it had been damaged, and found two theater tickets on one of the seats and a letter which said, “We’re very sorry. We took your car because of an emergency.”
Mr. and Mrs. Smith went to the theater with the two tickets the next night and enjoyed themselves very much.
