Your body is special﹣no two people in the world are the same．Although you are different from everyone else，you have exactly the same body parts as the people around you，doing different jobs that keep all of us alive．
What is inside my head ？
Your head holds the most valuable part of your body in it﹣your brain．As you are reading，your eyes send pictures to your brain which makes meaning from what you see．Your brain heIps you to remember and think，and makes sure your body is doing what it should do．
What is my skin for ？
Your skin covers your body．In most parts of your body，the skin is just as thick as 0.5cm．If you cut your skin，it will have a quick cure（治愈）and stop viruses（病毒）from getting into your body．Your skin also helps you feel the heat and coldness of the environment around you．Hair grows from inside the skin．When you feel hot，extra heat comes out through your skin．As a result，your body temperature drops．
How do I move ？
Muscles（肌肉） are found in most parts of your body． They work with your bones to help you move﹣ whenever you cry or smile， eat or speak， walk or dance， etc．
What does my heart do ？
Your heart is a very special muscle． It is a little bigger than your fist（拳头）and grows bigger as you do． If you place your hand on your heart， you will feel your heart beating which pushes blood to move around your body．

Did you know that tea，the most popular drink in the world（after water）was invented by accident？Many people believe that tea was first drunk about 5，000 years ago．It is said that a Chinese ruler called Shen Nong was the first to discover tea as a drink． One day Shen Nong was boiling drinking water over an open fire．Some leaves from a tea plant fell into the water and remained there for some time．It produced a nice smell so he tasted the brown water．It was quite delicious，and so，one of the world's favorite drinks was invented．
A few thousand years later，Lu Yu，"the saint of tea"，mentioned Shen Nong in his book Cha Jing．The book describes how tea plants were grown and used to make tea．It also discusses where the finest tea leaves were produced and what kinds of water were used．
It is believed that tea was brought to Korea and Japan during the 6th and 7th centuries．In England，tea didn't appear until around 1660，but in less than 100 years，it had become the national drink．The tea trade from China to Westerm countries took place in the 19th century．This helped to spread the popularity of tea and the tea plant to more places around the world．Even though many people now know about tea culture，the Chinese are without doubt the ones who best understand the nature of tea．
