Light travels at a speed which is about a million times faster than the speed of sound. You can get some idea of this difference by watching the start of a race. If you stand some distance(距離) away from the starter, you can see smoke from his gun before the sound reaches your ears.
This great speed of light produces some strange facts. Sunlight(太陽光) takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light that you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km. per minute. In some cases, the light from one of tonight’s stars had started on its journey to you before you were born.
Thus, if we want to be honest, we can’t say, “The stars are shining tonight.” We have to say instead, “The stars look pretty. They were shining four years ago, but their light has only just reached the earth.”

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.
