Do you think laughter can help you deal with pain? Scientists from Britain did two experiments(实验). The first was done in a lab. People wore special wristbands(腕带). Some of them were asked to watch comedies while others watched serious programs. Then the scientists tightened(勒紧)the wristbands to see how much pain the people could feel.

The other test was done at an art festival. Some people watched a comedy show and others watched a drama(戏剧). At the same time, they had to put their backs against the wall and keep their legs bent(弯曲的)just like sitting on a chair. They did this before and after the show.

Scientists found that just 15 minutes of laughter improves people's ability to stand pain by 10%. However, the serious programs and the drama didn't make a difference to pain at all.

The study found that the magic power of laughter comes from endorphins(内啡肽). These are chemicals(化学物质). They are produced by the human body. They make you feel less pain and can make people feel happier. Exercise can produce endorphins. Your muscles(肌肉)move in and out when you are laughing. Scientists believe that this makes your muscles tiring, so we start to produce endorphins.

Scientists also found that the only real and relaxing laughter works not just polite laughter.

Next time you have a headache, get together with a group of Mends, watch a funny movie and laugh. You will soon feel a lot better because laughter is the best medicine.

How do people find their ways? At first, people did it by looking at the sun, the moon and stars. Later, we started to use the compass(指南针). Today, there are navigation satellite systems.

A navigation satellite system uses groups of satellites. They send information to a receiver, such as your smart phone. Then they can find where you are.

The earliest navigation system is the Global (全球的) Positioning SystemGPSof the United States. The US has put 24 satellites into space to make sure GPS can locate a person correctly and globally. Russia's GLONASS and European Union's Galileo can also work globally.

The BeiDou Navigation Satellite System BDSis China's homegrown navigation system. It was set up in 2000. With it, China became the third country to build a navigation system after the US and Russia.

BeiDou can find you wherever you are. It helps you go faster by finding shortcuts and using correct directions. When you are in trouble and call the police, they will know exactly where you are if you have a smart phone that uses BeiDou.

Today, there are more than 20 BeiDou satellites above our head. And the system is able to offer open services to the AsiaPacific area.

China plans to send more BeiDou 3 satellites into space. BeiDou3's position accuracy(精确度) is less than five meters. By 2020, the BeiDou system will have 35 satellites and begin serving Globally.
