—It doesn't matter.

    Lu Yu had an unusual life. He lived in the Tang Dynasty. As a homeless child, he lived in Longgai Temple (寺庙) and studied there including boiling tea. Jingling Prefect (太守) Li Qiwu liked the smart boy when Lu Yu was thirteen. He not only gave Lu Yu books as gifts but also introduced him to a famous teacher. Lu Yu learned from his teacher until he was nineteen. He also made good friends with famous people. They often traveled, tasted tea and talked about poems together.

    At the age of twenty-one, Lu Yu started to study different kinds of tea. He left Jingling and traveled around the country to search for famous tea. To study tea picking and tea making skills well, Lu Yu lived a long life as a recluse (隐居者) in Tiaoxi. After that, he lived in Miaoxi Temple, collecting, checking, studying and reading documents (资料) about tea. Over years, he finally wrote the first book on the study of tea. That was the book Tea Classic (《茶经》) , which was also the first book in the world on tea studies. This book has over seven thousand Chinese words, including the production place, the morphology (形态) and the growing environment of tea trees as well as tea picking, tea drinking and tea production tools and methods.

    Tea Classic has a great influence on Chinese tea culture. Lu Yu is still called Tea God today.

    You and your family are planning a picnic for tomorrow. But you want to1the weather forecast (预报) first to see whether there will be rain or not. Your father turns on the television and the family listens to the2making the weather report.

    "It will be partly cloudy tomorrow morning, 3clearing by early afternoon. The high tomorrow will be 85."

    As there will be no rain, the whole family feels4. Without the weather forecast, you would not know this, and you would just have to take your chances. But now you can plan your picnic5worrying whether it will rain or not.

    The man you can thank for this is Cleveland Abbe. He is known as the father of the Weather Bureau. He was the first person to publish6weather forecasts in the United States.

    Abbe began his daily weather bulletins (简报) in 1869. They were based on weather7he drew from telegraphed reports of weather conditions. Because of their accuracy (准确) , the reports were8.

    Congress (国会) became9in Abbe's weather reports. They made Abbe a meteorologist (someone who studies weather conditions) , and he10issuing (发布) forecasts three times a day. He was the first official forecaster of the US Weather Service. Because he often forecast probable storms, Abbe earned the nickname of "Old Probabilities".

    Who invented toys? It's hard to believe millions, maybe billions of people have invented toys. Most of these people are kids. Kids invent toys from all kinds of materials, such as stones, sticks, paper, even clothes. And these toys are in different shapes; round, square, and so on.

    Sometimes adults invent toys, too, but in many cases (在许多情况下) , they don't actually invent the toy but take a toy that has been invented somewhere before and make it popular. Take the yo-yo for example. Yo-yos have been around for thousands of years. We know this because yo-yos have been found in ancient graves (坟墓) in some countries. This is how we know that stone yo-yos were used back in ancient Greece. In the 1800s, they became very popular as children's toys, first in England and then in the United States. Then people got tired of them for a while until Donald Duncan went into the yo-yo business. He hired "yo-yo men" to demonstrate (示范) and sell yo-yos door to door. This way, yo-yos got popular little by little. Today the name Duncan still goes with yo-yos, one of the most popular toys around the world.

    Another example is teddy bears. Teddy bears, one of the most popular toys, were named after a president of the United States, although he didn't invent them. President Teddy Roosevelt was a hunter (猎人) . He was good at hunting and on one of his hunting trips he had met a bear. That led to editorial (社论) cartoons showing pictures of President Roosevelt and a cute little bear. Somehow that led to cute, sewed (缝制的) bears for little kids to play with.

    The biggest secret about invention is that anybody can do it! Perhaps this sounds crazy, but it's true. Maybe you have the wrong idea about invention, so read on to discover the truth.

    Wrong idea 1: An invention has to be something completely new.

    Invention means creating something "new", but the idea could come from something that already exists (存在) . The Wright brothers, for example, got the idea of building a "flying machine" from watching birds.

    Wrong idea 2: Inventors are born, not made.

    There are a lot of factors (因素) that make invention possible. Take Mozart for example. He was born with a talent for musical composition. But other factors were also important for his creativity. His father was a music teacher, and Mozart practiced for hours every day, from the time he was four years old. Thomas Edison said that being an inventor was "99% hard work and 1% inspiration"!

    Very successful creators don't give up when they get something wrong. As one inventor said, "A failure is the right answer to the wrong question."

    Wrong idea 3: Inventors are always old people.

    Don't believe that you can't invent anything when you are young. Here are two examples of young inventors: Louis Braille went blind when he was a child. When he was fifteen, he invented a system of reading and writing for blind people that is still used in most countries today.

    As a young man, George Nissen was watching some artists performing in a show. He watched how they fell into the safety net and then jumped back up again. This gave him an idea, and he invented the trampoline (蹦床).

    When feeling tired, lots of people are used to drinking coffee. It is without that coffee is a popular drink all over the world. Coffee has been a part of people's life for thousands of years. People drink coffee with great . But do you know how it ?

    Many centuries ago, there was a farmer called Kaldi in Arabia. One day, he was watching his sheep. All of a , he noticed that his sheep became very active after eating the red fruits from a plant. So he ate some. To his surprise, he didn't feel tired anymore. He picked some fruits in a and sent them to a monk (修道士) . The man told him about that. The monk also ate that fruit and he had the same experience. The monk ground (研磨) the red fruits and put them in water and then served it to the other people. They felt fresh drinking it. In fact, the red fruit was the coffee fruit.

    Coffee drinking began in Arabia. In the 17th century it to Britain. In 1650, the first coffee house of the world was opened in England.
