Although tea wasn’t brought to the Western world until 1610, this beverage was discovered over three thousand years before that. According to an ancient Chinese legend, the emperor Shen Nong discovered tea when he was boiling drinking water over an open fire. Some leaves from a nearby bush fell into the water and remained there for some time. The emperor noticed that the leaves in the water produced a pleasant smell. Later he decided to taste the hot mixture. It was quite delicious. And in this way, one of the world’s favorite drinks was invented.ReadingDo you know when basketball was invented?If you travel around China you will notice a very popular activity everywhere you go— basketball. This much-loved and active sport is enjoyed by all, for fun and exercise.The sport of basketball is a little more than a hundred years old. It is played by more than 100 million people in over 200 countries including China, where basketball has been played in parks, schools, and even in factories.Basketball was invented by a Canadian doctor named James Naismith, who was born in 1861. When he was at college, his class was once asked to invent a new game that could be played indoors during the long winters. Dr Naismith created a game to be played on a hard wooden floor, so the safety of the players was important. Knocking into players and falling down would be dangerous.Dr Naismith divided the men in his class into two teams, and taught them how to play his new game. The aim of basketball is for players to try to get a ball intothe “basket”: a net hanging from a metal hoop. Players shoot from below the basket, and sometimes the “backboard” is used for guiding the ball into the basket. Players move towards one end of the court while throwing the ball to each other.It is believed that on December 21st, 1891, the first basketball game in history was played. Then in 1936/ in Berlin, it became an Olympic event. A team from China took part, and although they didn’t win they used the experience to help develop the game at home. Since then, the popularity of basketball has risen worldwide, and the number of foreign players in America’s NBA （National Basketball Association）has increased. Basketball has also become a more popular sport for people to watch, and many young people dream of becoming famous basketball players.。
