When we have small cuts in the skin(皮膚), 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(細胞). Cells grow and make new cells. Most cells are very small and we can't see them with our eyes. Different cells have different uses. Our skin cells are special ones. The cells on the outside of our skin are old dead cells. New skin cells are right under the outside. These are the living skin cells. They 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. Outside skin cells fit together closely with no gaps between them. When you cut yourself, you can harm your skin cells. A small cut will not be harmful. 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(層) of skin cells. Finally, new cells will grow until the gap disappears. In this way, your skin can grow and get well itself. How amazing the small 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.

Do you want to live a happier, less stressful(有壓力的) life? Try laughing for no reason at all. That’s how millions of people start their day at Laughter(笑聲) Clubs around the world and many doctors now think that having a good laugh might be one of the best ways to stay healthy.
The first Laughter Club was started in Mumbai, India, in 1995 by Dr. Madan Kataria.“Young children laugh about 300 times a day. Adults laugh between 7 and 15 times a day,” says Dr. Kataria. “Everyone is naturally good at laughing — it’s the common language. We want people to feel happy with their lives.” There are now more than 500 Laughter Clubs in India and over 1,300 in the world.
Many doctors are also interested in the effects(效果) of laughter on our health. According to a 5-year study at the UCLA School of Medicine in California, with laughing there is less stress in the body. Laughter improves our health against illness by about 40%.
So what happens at a Laughter Club? I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest, I wasn’t interested in laughing with a group of strangers, and I was worried about looking silly. Our laughter teacher told us to clap our hands and say “ho ho ho, ha ha ha” while looking at each other. However, our bodies can’t tell the difference between real laughter and unreal laughter, so they still produce the same healthy effects.
Surprisingly, it works! After ten minutes everybody in the room was laughing for real and some people just couldn’t stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you’re under stress, then start laughing. You might be very pleased with the results.

(G=girl W=woman)
G:Life must have been difficult when you were a kid.
W:Oh, not really. 1 .
G:Well, you didn’t have many modern inventions. Like, you probably didn’t have a telephone, right?
W:Of course we did! How old do you think I am?2 .
G:How about cars? I bet cars weren’t invented yet.
W:Sure they were. Cars were invented in 1885. My family had a car. I think you need to take a history class, Alice.
G:Ha, Ha! Well, 3 .
W:No, we didn’t. The TV was invented around 1927, I think. Some friends of mine had one. But in those days, TVs were really expensive, and we couldn’t afford one.
G:And I bet you didn’t have calculators and computers and stuff. 4 We learned in school that hand-held calculators were invented in 1971 and personal computers were invented in 1976.
W:You’re right. 5 . But I do now!
Did you have a TV? Why do you say that? The telephone was invented in 1876. I didn’t have those things when I was young. That’s something I do know. I am good at it. Thank you, my dear mom. |
