Who invented tea? Do you know that tea, the most popular drink in the world（after water）, was invented by accident? 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. After you read, answer the 4 questions following the article. 1. What is the article about? It is about the invention of tea. 2.When was it invented? It was invented over three thousand years before 1610. 3.Who was it invented by? It was invented by Shen Nong. 4. How was it invented? The emperor Shen Nong noticed that the leaves from a nearby bush in the water produced a pleasant smell. He tasted the hot mixture. It was quite delicious. 3b Writing an article On page 72 you will find notes in the box on the left. Write an article using the notes about the invention of the flying disk. From pie plate to flying disk A baker named William Russel Frisbie, of Warren, Connecticut, and later of Bridgeport, came up with a clever marketing idea back in the 1870s. He put the family name in relief on the bottom of the light tin pans in which his company’s homemade pies were sold. The pans were reusable, but every time a housewife started to bake a pie in one, she would see the name Frisbie and, it was hoped, think, "How much easier to buy one". Eventually Mr. Frisbie’s pies were sold throughout much of Connecticut, including New Haven. There, sometime in the 1940s, Yale students began sailing the pie tins through the air and catching them. A decade later, out in California, a flying-saucer enthusiast named Walter Frederick Morrison designed a saucer-like disk for playing catch. It was produced by a company named Wham-O. On a promotional tour of college campuses, the president of Wham-O encountered the pie-plate-tossing craze at Yale. And so the flying saucer from California was renamed after the pie plate from Connecticut. Of course the name was changed from Frisbie to Frisbee to avoid any legal problems. 4a Thinking and invention We all have things that we don’t liking doing. Why not think of an invention that could help you. Write the details of your invention in the chart on page 72.

The basic umbrella was invented over four thousand years ago. We have seen evidence of umbrellas in the ancient art and artifacts of Egypt, Assyria, Greece, and China. These ancient umbrellas or parasols, were first designed to provide shade from the sun. The Chinese were the first to waterproof their umbrellas for use as rain protection. Soon after telescopes were invented, people started to fasten two of the long tubes together to make binoculars (from the Latin "two eyes"). Around 1900, a German physicist named Ernst Abbe made a pair of binoculars using prisms. The triangular prisms each reflected the incoming light twice. This meant it was possible to make a shorter instrument. The two prisms also flipped the image upright. Camera The history of the camera - Camera Obscura, photography, the significant processes of photography, and who invented the polaroid and photographic film. In 1818, Baron von Drais introduced a machine to the public in Paris. It had two in-line wheels connected by a wooden frame. The rider sat astride and pushed it along with his feet, while steering the front wheel. Just for fun! Look at the pictures below and tell about what you see.

Part 2: Teaching Resources（第二部分：教学资源） I.What is invention? An invention is a new thing that someone has made. The computer was an invention when it was first made. We say when it was "invented". New things that are made or created are called inventions. The car is an invention that everyone knows. Ideas are also called inventions. Writers can invent characters, and then invent a story about them. II. What is an inventor? An inventor is a person who creates new inventions, typically technical devices such as mechanical, electrical or software devices or methods. Although some inventors may also be scientists, most of them are engineers in fact as they base their work on the discoveries of other scientists, experimenting with practical applications and combinations of those discoveries, and with improvements and combinations of existing devices, to create new useful devices. The system of patents was established to encourage inventors by granting limited-term monopoly on inventions that are judged sufficiently novel. This system is nowadays frequently considered as being abused, especially in the United States, and some have called for reform or even abolition of the patent system. In the U.S., however, the patent right originates from the Constitution, so inventors will likely continue to protect their inventions that way for many years to come. The capacity to invent can be developed. See TRIZ, the theory of inventive problem-solving. |
