How could we tell time if there were no watches or clocks anywhere in the world?The 45 was probably the world's first "clock", except in the far north, where the Eskimos live. There, it's dark most of the winter, and 46 most of the summer. But 47 most of the world, people have used the sun for day. 48 you don't have a clock that shows time, you still know that when the sun shines, it's day, and when it's dark, it's night.

Maybe you have the wrong idea about inventing, so read on to discover the truth.Wrong idea No. 1:An invention has to be something completely new.Inventing means creating something "new", but the idea could come from something that already exists(存在). The Wright brothers, for example, got the idea for building a "flying machine" from watching birds.Wrong idea No. 2: Inventors are born,not made.There are a lot of factors(因素) that make invention possible. Take Mazart, 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 No. 3: Inventors are always old people.Don't believe that you can't invent something 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).54. got the idea for building a "flying machine" from watching birds.A. MazartB. George NissenC. Louis BrailleD. The Wright brothers55. The underlined word "talent" probably means .A. 态度B. 品质C. 天赋D. 能量56. Which of the following is the writer's opinion?A. Anybody can do inventing.B. Inventors are born, not made.C. Inventors are always old people.D. An invention has to be something completely new.57. The best title for the passage would be .A. How to Perform in a ShowB. Be a ComposerC. How to Help Blind PeopleD. Be an InventorBTo us, it seems so natural to put up an umbrella to keep the water off when it rains. But in fact the umbrella was not invented as protection against the rain. Its first use was as a shade(遮蔽) against the sun.Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, back in the eleventh century BC.We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and power(权力). In the Far East in ancient times, the umbrella was allowed to be used only by those in high office or by royal people such as the kings or queens.In Europe, the Greeks were the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece, but it is believed that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans. During the middle ages in Europe, the use of the umbrella almost disappeared. Then it appeared again in Italy in the late sixteenth century. And again it became a symbol of power.Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn't until the twentieth century that the umbrellas for women began to be made in all kinds of colors.58. Ancient people first used umbrellas as .A. a symbol of honorB. protection against the sunC. a symbol of powerD. protection against the rain59. According to the passage, the umbrella was probably first used in ancient .A. EgyptB. BabylonC. RomeD. China60. The underlined word royal might mean " " in Chinese.A. 皇室的B. 富裕的C. 中产的D. 平民的61. According to the passage, which of the following is NOT true?A. The ancient Greeks used the umbrella in their daily life.B. Europeans hardly used the umbrella during the middle ages.C. The umbrellas for women were made colorful in ancient times.D. The style of the umbrella hasn't changed a lot since it was invented.62. This passage is mainly about .A. the sales of the umbrellaB. the differences among umbrellasC. the invention of the umbrellaD. the history and the use of the umbrellaCThomas Edison was a great American inventor. He was born to a poor family in 1847. His mother taught him at home. He often observed things carefully and he made over 1,300 inventions during his life time. He was often said to be the greatest genius(天才) of his age. There are only a few men in all of history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius. “There is no such thing as genius,” Edison said. He also said that what people called genius was mostly hard work. But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to learn what could usefully be done with them.Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure.Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what ideas he had about life. “Work,” he answered back, “discovering the secrets of nature and using them to make me n happier.” He said he had enough inventions in his mind to give him another 100 years of work.63. Edison was .A. interested in changing people's ideasB. interested in discovering the secrets of natureC. very much uninterested in natureD. uninterested in making people happier by discovering the secrets of nature64. Which of the following is NOT TRUE according to the passage?A. Many other people have changed Edison's lifeB. Edison has changed the lives of many other peopleC. Only a few men in history can change other people's livesD. Edison invented the electric light65. The last sentence in the passage most probably implies(意指) .A. people of his time were ready to give Edison another 100 year's workB. Life is too short for Edison to invent more for human beingsC. Edison made 100 inventions in his lifeD. Edison was able to live and work for 100 yearsD1970 was World Conservation Year. The United Nations wanted everyone to know that the world is in danger. They hoped that governments would act quickly in order to “conserve” nature. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 866 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and water, and everything that grows and lives. We can't live without these things. If we continue like this, we shall destroy ourselves.What will happen in th e future? Perhaps it is more important to ask “What must we do now?” The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridgesacross rivers in forests, and so on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometers of their river. Young people may hear about conservation through a record called “No one's going to change our world”. It was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve wild animals.66. “No one's going to change our world” was .A. an important book published in 1970B. an idea that nobody would acceptC. a record calling on people to conserve natureD. a rule worked out by the United Nations67. What is the most important thing for us to do to save our world?A. We should plant more trees and flowersB. we should clean the banks of our riversC. we should know what will happen in the futureD. we should know what we must do and begin to do it now68. What's the main idea of the passage?A. 1970 was World Conservation YearB. The United Nations wanted everyone to know that the world is in dangerC. Conservation is necessaryD. It is the young people who are helping to save our world七、短文7选5(5选5等)（共4小题；共8分）I'd just got in a taxi at the railway station when suddenly I found one of my suitcases(手提箱) missing. Just then, I saw a young man, not very far, opening it and taking out valuables. "Stop thief! Stop thief!" I shouted and threw open the car door and rushed out to him, followed by the driver and some passers-by. 69. My driver caught him by the neck and took out the valuables from his trouser pocket and put them back into my suitcase.Half an hour later, I sat back in the taxi and breathed a sigh of relief (松了一口气). But as I checked those stolen things, I became very surprised, unable to speak. 70. And a blood test report of a 58-year-old woman appeared. I suddenly realized that the taxi driver must have mistaken the thief's things and put his into my suitcase.71. But this story keeps coming back to me. Was the young man a habitual thief or a dutiful son who had been driven to find money to save his mother's life?72. How I wish I had gone back that afternoon to return the money and the report and say sorry to him. For the first time in my life, I realized that hate and love are very close.A. My heart aches for him.B. Two years has passed since then.C. The train left the station very quickly.D. Very soon we caught up with the thief.E. Before my eyes was 200 yuan instead of 100.八、阅读与表达(问答式)（共5小题；共10分）DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.People have been trying to understand the human body for a long time. In I860, Mr Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages. They're written in the DNA with a special language.In 1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell(细胞) to build its parts, Scientists have now found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.Most people hope that this will help to make better medicine and help sick people; Other people worry that when we Icam more “words” and find out more information, we will use it in the wrong way, just to make people more attractive(有吸引力的), or stop sick people getting jobs.根据短文内容，完成下列小题。
