A man came back home from work late, he was tired And he was surprised to find his ten-year-old son waiting for him at the door.
"Daddy, how much money do you make an hour?"
"If you want to know, I make $20 an 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 money to buy a toy or some other rubbish, then go straight to your room and think why you are being so selfish !"
The little boy quietly went to his room and closed the door. After about an hour, the father calmed down, and started to think, "Maybe he really needs to buy something and he didn’t ask for money very often."So he went to the little boy’s room.
"Sorry! Maybe I was too hard on you just now," said the man. "Here’s $10."
"Oh, thank you, Daddy!"the boy said happily. Then, the boy took out some coins. When the father found that the boy already had some money, he got angry again.
"Why do you want more money after you already have some?" the father shouted angrily.
"Because I didn’t have enough, but now I do," the little boy answered, "Daddy, I have $20 now. Can I buy an hour of your time? Please come home early tomorrow. I would like to have dinner with you."
【小题1】How much does the man make if he works an hour?

A recent survey of 2000 parents in Britain showed that they are often afraid of science questions asked by their curious children only because they have no idea what the answer is. Here is a list of some simple questions that you can ask your parents to see if they know the answers.
Q: Why is the sky blue?
A: You probably know white sunlight is made up of seven colors. While it moves in a straight line when going through space, it starts to divide as it hits “raised area” in the atmosphere. The ones with longest wavelengths pass through easily. The blue , however , can be taken in by the gas molecules (分子) because it has a shorter wavelength , which in turn scatters (使分散) it in different directions. That’s why when you look up at the sky, it appears to be blue.
Q:Why does the moon sometimes appear during the daytime?
A: The simple answer to that is because just like any other object it is being lit by the sun. As long as it is around 45 degrees or even 90 degrees off the sun, it will receive light and be able to be seen. The only time it is not able to be seen during its 28-day orbit (轨道) around the earth is when it is right between the earth and the sun. That’s because its back , which is not lit by the sun, is facing us.
Q: Where do birds/ honeybees go in winter?
A: While the bird part is quite easy, since a lot of them get together and travel, the honeybee part is likely to puzzle your parents. It turns out that these busy insects stop being that active when the temperature drops below 50°F. Instead ,they get together in the lower central area of the hive （蜂巢）and form a ball around their queen. This helps keep both warm enough to survive the cold winter months.
