Last Sunday the Greens went to climb the hill. When they got home, it was very late. Mr. Green opened the front door and they both went into the house. Because it was too late, Mrs. Green turned on the light. Just they wanted to come into the bedroom, Mrs. Green suddenly said, “ Listen, there is someone in our bedroom.” They stood quietly outside the door. They could hear some voices in the room.
“There are two men in it. They are talking.” So Mr. Green began to shout. “Who is there?” But no one answered. Mr. Green opened the door quickly and turned on the light. There was no one there. Mr. Green found something and laughed. The radio was still on! “I forgot to turn it off this morning.” Mr. Green said.

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.

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

2.How long can’t the moon be seen during the daytime in a month?

A. 2                             B. 28                           C.30                                      D. 31

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.

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?

There are some easy things you can do to protect(保护) the environment and the earth. Choose ideas from the list or come up with a few of your own.
● Plant flowers, grass or trees.
●Whenever you visit a park or beach, take away what you bring there----keep rubbish in a bag until you can put it in a dustbin (垃圾箱).
●Turn off the lights, TV sets when you leave the room. This saves (节约)a lot of electricity.
●Turn off the tap (水笼头)when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.
●Keep the doors and windows closed in winter to keep warm air in.
●Give your old books and magazines to a library instead of throwing them away.
●Give your old clothes to poor children you know instead of throwing them away.
●Use both sides of paper.
●Stop pouring (倒)dirty water into the rivers or the lakes nearby (附近).
●Encourage all your friends to do the same things you do to help protect the earth.
You don’t have to wait until Earth Day to do these things. Make every day Earth Day.
If everyone makes a contribution (贡献)to protecting the environment, the world will become much more beautiful.
