世纪百通期末金卷系列答案It is always more important to know how to study by oneself. It is quite easy to learn something in language or formula (公式 )in maths, but it is difficult to use a formula to find the answer to a maths problem. Great inventors do not get everything from school, but they can invent many things and change the world a lot. Though Thomas Edison invented many things, he didn’t have much school education. How do they do all this ? A lot of things are not taught in the classroom. They get knowledge( 知识 ) from books outside school. They work hard all their lives, and the most important thing is that they know how to use their heads.

When Steven was a young boy, he moved quite often with his family and so he never had many friends. He spent a lot of time on his own and liked to play with electronic(电子的)things. Steven had a neighbour, Steve Wozniak. Steve was a little bit younger than Steven but also liked to play with electronic things. Steven made a microphone(麦克风)and Steve asked him many questions about it until he understood how it worked. Steven liked the fact that such a young boy was also interest ed in electronic things and so he taught him everything he knew.
When they were a little older and knew more about electronic things, they made a “blue box”. People could make free phone calls by breaking into the phone company’s system with this box. They sold this to many people even though it was illegal(非法的), but this is not why they are famous today.
Steven and Steve were the inventors of the first PC—personal computer. They called their first computer the Apple I. They invented it only for fun and to make themselves known among their friends. They did not think it would become so popular. They just liked playing computer games on it. Their computer made it cheaper and easier for people to own and use a computer. Their PCs were so popular that they made a new PC called the Apple II. Soon many schools, families and factories were using their computers.

Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.
1. Most historians hold that the Chinese invented fireworks in the 9th century when they discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.
2. In May of 1886, a law led John Pemberton, a pharmacist(药剂师), to rewrite the formula(配方) for “Pemberton’s French Wine Coca”, his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated(碳酸) water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world-wide drink came into being.
3. During World WarⅡ, scientists at the University of Birmingham invented the magnetron(磁控管)—an important heat-producing part of the microwave oven. While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels(仁), and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.
