When we have small cuts in the skin (皮肤), something strange may happen. The cuts are able to heal (痊愈) themselves in a couple of days. How does this happen? Read on, and you will find out the secret.
Every living thing on the earth is made up of cells (细胞). Cells grow and make new cells. Most cells are very tiny and we can’t see them with our eyes. Different cells have different uses. Our skin cells are special ones. The cells on the surface (表面) of our skin are old dead cells. New skin cells are right under the surface. These are the living skin cells. They do work for our bodies. They help protect our bodies and heal cuts.
Our bodies make skin cells all the time. As the old cells fall off, new cells grow in the same place. Each person makes about 18 kg of skin cells during his or her life. Surface skin cells fit together closely with no gaps between them. When you cut or burn yourself, you can harm your skin cells. A small cut will not do much harm. Your skin will quickly heal itself by making new skin cells. How do skin cells work? First, the cells near the cut get bigger and move into the gap. Next, these bigger cells meet in the middle. They form a new layer (层) of skin cells. Finally, new cells will grow until the gap disappears completely. In this way, your skin can grow and get well itself.
How amazing the tiny cells are! Next time you have a cut, don’t worry about it. Maybe in a few days, you will be surprised to find it healed.The underlined word “gaps” in the passage means “_________” in Chinese.
| A．突起 | B．条纹 | C．缝隙 | D．代沟 |

In the sunny night, look up at the clear night sky. You can probably see thousands of stars. The biggest thing you’ll see, of course, is the moon. For thousands of years, people have wondered about this big thing in the sky.
Earth’s moon is a satellite. A satellite is a body that orbits(环绕轨道运行)a planet. All moons are satellites, and many planets have them. Some have many moons. Earth, of course, only has one. It’s a special moon, though. It’s the fifth largest moon in the solar system!
In fact, the moon is much smaller than the sun. But it’s much closer to Earth, so it looks as big as the sun. The moon is so close that you can see its dark and light spots(斑点)without a telescope. Men flew and landed on the moon’s surface many times by spacecrafts in the 1960s and 1970s. Neil Armstrong was the first human to step on the moon. He walked on the moon on July 20th, 1969. The flights to the moon have helped us learn much about it. Astronauts even brought rocks home with them!
There’s still a lot to learn about the moon. Now people still can’t live on the moon because it does not have oxygen or water like the Earth. But I’m sure that humans can live there one day in the future.

How green are you? Do you know how to be green?
We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.
Reduce
Reduce means “use less”. Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
Reuse
Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup of a paper bag. It’s better to use a china cup and a lunch box because you can use them again.
Recycle
Recycle means “change things into something else”. Though it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.
So please remember these three words: reduce, reuse and recycle.
| A．How to produce things. | B．How to burn things. |
| C．How to help others. | D．How to be green. |
| A．Don’t waste things. | B．Always throw away old things. |
| C．Always buy new things. | D．Buy too many things from abroad. |
| A．You can burn them. |
| B．You can use them again. |
| C．You can throw them away. |
| D．You can change them into something else. |
| A．waste, reuse and recycle | B．repair, burn and recycle |
| C．reduce, reuse and recycle | D．reduce, waste and recycle. |
| A．a menu | B．a dictionary |
| C．a storybook | D．a magazine |
