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.

When Amelia opened the door, she was very surprised. Instead of seeing a human outside, she found a small creature(生物)with very large ears.

“W-w-what do you want?” she cried. Amelia was worried that she had made a mistake in letting the creature in.

“Oh, some help, please. Nothing to worry about,” the creature replied as if it could read her mind. “My name is Hastings, and I come from a planet called Haste. You probably have not heard of it because it’s not in your galaxy (星系).”

“Sorry, I haven’t. However, I’m not sure if I can help you.” she replied. “But first, would you like some tea? I was so amazed to see you could speak that I forgot my manners.”

“Thank you, but I’m fine. Manners! Yes! That’s what I’ve come about. It is a good habit to have good manners,” Hastings said. “Unluckily, our children on planet Haste are so hasty that they forget them. So I thought I would come to Earth, and ask for some advice. Do you think you can be of help?”

“Well, I don’t know how,” said Amelia.

“I was wondering if you could write a blog(博客). On Haste, our children take more notice of things on their tablet screens than they do of their parents,” Hastings said sadly, “Too much technology in our lives”.

“That’s terrible. Every child should listen to their parents. After all, parents teach you good and bad habits for life, including manners. They do not just teach you about the right food to eat, but also about things like time management and having proper schedules. If you don’t have these things, then your life will be in a mess. You won’t be able to make right decisions. Then there are not things like honesty and thankfulness. Developing these is as important as proper hygiene(卫生)and taking exercise,” said Amelia.  

“Exactly. 33 , ” said Hastings. “Now let’s make a plan.”

When 19-year-old Sophia Giorgi said she was thinking of volunteering to help the Make-A-Wish Foundation (基金会), nobody understood what she was talking about. But Sophia knew just how important Make-A-Wish could be because this special organization (组织) had helped to make a dream come true for one of her best friends. We were interested in finding out more, so we went along to meet Sophia and listen to what she had to say.

Sophia told us that Make-A-Wish is a worldwide organization that started in the United States in 1980. “It’s a charity(慈善机构) that helps children who have got very serious illnesses. Make-A-Wish help children feel happy even though they are sick, by making their wishes and dreams come true,” Sophia explained.

We asked Sophia how Make-A-Wish had first started. She said it had all begun with a very sick young boy called Chris, who had been dreaming for a long time of becoming a policeman. Sophia said lots of people had wanted to find a way to make Chris’s dream come true --so, with everybody’s help, Chris, only seven years old at the time, had been a “policeman” for a day. “When people saw how happy Chris was when his dream came true, they decided to try and help other sick children too, and that was the beginning of Make-A-Wish,” explained Sophia.

Sophia also told us the Foundation tries to give children and their families a special, happy time. A Make-A-Wish volunteer visits the families and asks the children what they would wish for if they could have anything in the world. Sophia said the volunteers were important because they were the ones who helped to make the wishes come true. They do this either by providing things that are necessary, or by raising money or helping out in whatever way they can.

1.Did Sophia know how important Make-A-Wish could be?
