You probably get a drink from your fridge. But people did not have fridges before the early 1900s. How did they keep things cool before then? In the past, it was difficult to keep food cold. Warm food . .spoils quickly. Before fridges were available, people used to get sick a lot or even die from eating spoiled food. People tried many different ways to keep things cold. However, none of these ways was perfect. 23 What was a better way? Putting food on ice. In 1000 BCE, people in China collected ice and snow. Then they dug holes under their homes and filled them with the ice and snow. After that, they put their food in the holes. In many countries, people continued to do this for about 2,000 years. There are a few problems with this way. First, ice and snow are not available everywhere. Second, ice melts（融化）. An American businessman named Frederick Tudor solved these problems. He wanted to carry ice to hot places. In the early 1800s, he sent a ship full of ice from Boston, Massachusetts, to the island of Maryinique. Almost all of the ice melted. After that happened, Tudor realized that he had to find a way to keep the ice frozen. In the end, he tried putting sawdust（锯屑） between the pieces of ice. It worked! People used to work hard to keep their food and drinks cold. Now, it's much easier. The next time you want a cold drink, imagine your life without a fridge. ( ) 1.How does the writer start the text?

The first bicycle was made of wood. It had two wheels but no pedals（踏板）. You didn't ride it—you walked it! It was called a “hobby horse” or “walking machine”. 63 The velocipede came next. Velocipedes had pedals. Pedals were a good idea. With pedals, people could ride instead of walking or pushing their velocipedes. But velocipedes were hard to ride on cobblestone（鹅卵石） streets, and so they were called “boneshakes”. Later, people rode a new kind of bicycle called a “high wheeler”. It was made of metal and had a high front wheel and solid rubber tires. It was more comfortable than a boneshaker, but people could fall off easily. Women didn't ride high wheelers because women at the time wore long skirts. They rode a machine with three wheels, called a “tricycle”. The next bicycle went back to two wheels of the same size. It had metal parts and pneumatic（充气的） tires and was called the “safety bicycle”. This design became the stand for modern bicycles. Then companies began to make bicycles for children. Now everyone enjoys bicycles! 1.从方框中选择合适的词补全时间轴。 Boneshaker Hobby Horse Tricycle High Wheeler Safety Bicycle 66 2.*回答问题。 Do you think the bicycle is a useful invention?

In school, Edison was often absent-minded, and his teacher did not think that he was very smart. In 1854 his family moved to Port Huron, Michigan, where young Edison sold candy and newspapers on trains from Port Huron to Detroit. These early sales experiences led Edison to discover his talents as a businessman and eventually（最 75 后） to found fourteen companies, including General Electric, which still exists today. Edison started his career as an inventor in Newark, New Jersey. In 1878 Edison formed the Edison Electric Light Company. During his first public demonstration（展示） of his incandescent light（白炽灯） bulb on December 31,1879, he said, “We will make electricity so cheap that only the rich will burn candles.” Light bulbs were not the only things Edison worked on. He also built the first industrial research laboratory in Menlo Park, New Jersey. There, Edison and his assistant, William J. Hammer, worked on the telephone, phonograph（留声机）, electric railway, and electric lighting. However, Edison did not invent many of the things he is said to have invented; he only improved them so that they could be sold to the public. He did not invent the electric light bulb, either. He did, however, start the first company that made and sold electric light bulbs. The only major invention that he actually did invent was the phonograph. It was his invention of the phonograph in 1877 that made him famous, and he became known as The Wizard of Menio Park（门洛帕克的奇才）, New Jersey. ( ) 1.What is the main idea of the passage? B A.Thomas Edison invented the light bulb, which has helped human to see in the dark. B.Thomas Edison did not invent many of the things he is said to have invented, but he did improve many of the inventions we use today. C.Thomas Edison was the first scientist to use an industrial research laboratory. D.Thomas Edison invented a lot of things, including the light bulb. 78 ( ) 2.What are some of the things that Edison worked on? A A.The light bulb, electric railway, and phonograph. B.The steam engine, fax machine, and television. C.The phonograph, computer, and telephone. D.The light bulb, camera, and phonograph. ( ) 3.What did Edison actually invent? D A.The light bulb. B.The telephone. C.The computer. D.The phonograph. 79 ( ) 4.Which of the following sentence can be used to best describe Edison? B A.He was absent-minded and not very smart indeed. B.He was a good businessman as well as an inventor. C.He was famous for his great invention: the light bulb. D.He was a businessman but not an inventor. ( ) 5.In which magazine would you most likely find this article? B A.Travel & Leisure. B.Discovery. C.Business Week. D.Culture. 80 三、书面表达。 小小发明，大大改变。我们的生活因为各种科技发明而日益便捷。假设你最喜欢的发明是智能手机（smart phone），请你根据以下提示，以“My Favorite Invention”为题，描述你最喜欢的发明。词数80—120，文章的开头已经给出，不计入总词数。 81 写作要点： 1.Favorite invention: smart phone 2.Reasons: ①small and light ②keep in touch with friends ③… My Favourite Invention Nowadays, different kinds of modern inventions make our life more and more convenient. ______________________________________________________________ ____________________________________________________________ Among these inventions, the smart phone is my favorite one.
