One day, a baby snail found that he had to carry a big and heavy shell at any time. He was confused(困惑的), so he went up to his mother and asked, “Why was I born with a shell that grew so hard and heavy?” His mother said, “Because we don’t have bones to hold us up. We can only move slowly, so we need a shell to protect us.”
The baby snail asked again, “The caterpillar(毛毛虫) has no bones either, and she can’t move quickly. Why can she live without a shell?” The mother snail answered, “That’s because a caterpillar will become a butterfly. She can fly high into the sky. The sky can protect her.”
The baby snail had one more question, “But the earthworm(蚯蚓) moves like us. He has no bones and he won’t turn into a butterfly. Why doesn’t he carry a hard and heavy shell?” His mother said, “He can dig a hole and hide in the ground, and then the earth can protect him.”
The baby snail then cried, “We are so poor! We have no protection from the sky or from the ground!” His mother smiled at him, “That’s why we have a shell. My dear, imagine that if we don’t have the shells, what will happen to us? Hot sun will dry out our bodies and we’ll have nowhere to sleep. What’s worse, we’ll die in the heavy rain. How terrible it is! We don’t depend on the sky or the ground for protection. We should depend on ourselves.”

Tea, coffee and cocoa(热可可饮料) are three major drinks all over the world. Tea is drunk by the largest number of people in the world. Tea, as well as silk and porcelain(瓷器), began to be known by the world over a thousand years ago and has been an important Chinese export since then.
Tea has a history of over 4,000 years and China is the home of tea. In ancient China, tea was used as a kind of medicine, while nowadays people drink tea daily.
Longjing, Pu’er, Wulong and Tieguanyin are all famous tea. Thanks to the mild climate and rich soil in Fujian, Zhejiang and Yunnan, tea is produced mainly in these provinces.
The word for tea in different languages came from Chinese, like “cha’i” in Russian. And the Japanese character for tea is written exactly the same as it is in Chinese.
Over the past centuries, Chinese people have developed their unique tea culture, which includes tea planting, tea leaf picking, tea making, tea drinking and so on. Tea is also popular in some sayings, like “A friendship between gentlemen is like a cup of tea”. In dances, songs, poems and novels, tea is often mentioned too.
