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.
【小题1】The sky looks blue mainly because the color blue in the sunlight_______.

A.has the longest wavelength among all the colors
B.cannot be taken in by the gas molecules
C.doesn’t hit “raised area” in the atmosphere
D.cannot pass through space successfully
【小题2】How long can’t the moon be seen during the daytime in a month?
A.2 B.28 C.30 D.31
【小题3】What do honeybees choose to do when the temperature drops below 50°F?
A.They choose to be active in the wild.
B.They choose to keep themselves warm.
C.They choose to travel to a warm place.
D.They choose to get together in the upper central area of the hive.
【小题4】What is NOT explained in the passage?
A.Why is the sky blue?
B.Why is the moon able to be seen during the daytime?
C.Why do birds travel in winter?
D.Where do honeybees go in winter?

Two people sit down to play Go(围棋).One of the players is an old man.He is now 89 years old.He has spent all of his life playing this game.The other person is a young woman.She has been playing Go for only three years.Before this,the woman was an expert at playing computer games.Now she plays Go the same way she played computer games-by becoming a machine herself.

They will play many games,until they know who the winner is.The woman shows no feelings but thinking about all the possible ways of placing her next stone.The old man,on the other hand,looks at the movements of her hands and of her face.This has always helped him to win.He wins the first three games.She wins the next game,and the man is surprised.He has never lost to a woman.The old man worries about the way the young woman is playing the game.He can't read her face; he does not understand her way of playing.
