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.

Do you want to live a happier, less stressful life? Try laughing for no reason at all. That’s how thousands of people start their day at Laughter Clubs around the world.
The first Laughter Club was started in Mumbai, India, in 1995, by Dr Madan Kataria. “Children laugh about 300 times a day. Adults laugh between 7 and 15 times a day,” says Dr Kataria. “Everyone’s naturally good at laughing — it’s the universal (共同的) language.” There are now more than 500 Laughter Clubs in India and over 1,300 worldwide.
Many doctors are also interested in the effects (影响)of laughter on our health. According to a 5-year study at the UCLS 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 the nearest club in the south of London to find out. I was quite nervous at the beginning of the class. I had no interest in laughing with a group of strangers, and I was worried about looking stupid (愚蠢的). Our laughter teacher told us to clap our hands (拍手) and say “ho ho ho, ha ha ha” while looking at each other. Although we couldn’t tell the differences between fake laughter and real laughter, they still produced the same healthy effects.
Surprisingly, it worked! After ten minutes, everybody there was laughing for real and some people just couldn’t stop! At the end of the class I was shocked by how relaxed and comfortable I felt. So if you’re under stress, then start laughing. The passage is probably taken from .
