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.

【小题1】Which of the following is the result of the study?

A Russian, a Cuban, an American businessman and an American lawyer were on a train traveling across England. The Russian took out a large bottle of vodka, gave each of the men a drink and then threw the rest half bottle of vodka out of the window. “Why did you do that?” asked the American businessman. “There’s too much vodka in my country,” said the Russian, “And really we have more than we will ever use.” A little later, the Cuban passed around fine Havana Cigars. Then he threw his out of the window. “I thought Cuba is not a rich country,” the businessman said. “But you threw that very good cigars out of the window!” “Cigars,” the Cuban answered, “are the cheapest in my country. We have more of them than we know what to do with.” The American businessman sat quietly for a moment. Then he got up, caught the lawyer by the arm and threw him of the window.
【小题1】The people in the story are from ______ countries.

A man came home from work late, tired, to find his 5-year-old son waiting for him at the door.
“Daddy, how much money do you make each hour?”
“If you must know, I make $20 each hour.”
“Oh,” the little boy answered, with his head down. He thought for a moment, looked up and said, “Daddy, could you lend me $10?”
The father was furious, “If you asked for the money to buy a toy or some other rubbish, then go straight to your room and think about why are you so selfish (自私)！”
The little boy went to his room with no words and shut the door. After a short while, the father calmed down, and started to think, “Maybe he really needs to buy something and he didn’t really ask for money very often.” So he went to the little boy’s room.
“Sorry！Maybe I was too strict with you just now.” said the man, “Here’s $10.”
“Oh, thank you Daddy!” he said happily. Then the boy took out some coins. When the father found that the boy already had money, he got angry again.
“Why do you want more money since you already have some?” the father shouted angrily.
“Because I didn’t have enough, but now I do.” The little boy replied, “Daddy, I have $20 now. Can I buy one hour of your time? Please come home early tomorrow. I would like to have dinner with you.”
