She is interested in the following things introduced in a magazine. Smart Schoolbag Forget to pack the books you need into your schoolbag in the morning rush? A schoolboy aged 11 has invented a schoolbag. It tells you which books to pack. A small computer and a scanner(扫描装置)are fixed in the bag. As each book is put into the bag，it is checked by the scanner. If any book is missing，a message will be shown on the computer screen to remind you. Weather Sweets Can you eat weather? A university makes that happen. It uses a 3D printer to create sweets based on the weather information of a certain day. The shapes of the sweets are affected by wind speed. The colors of the sweets are decided by temperature. The sweets act as a weather record of the day when they are made. Sunrise Bed It's hard for you to get up in the morning，isn't it? To help you get up，a company has created a “tool” —a sunrise bed. It wakes you up gently as sunrise does. Lights built into the bed switch on and start to get brighter and brighter. When the lights are fully on，soft music will begin to play. It will be louder and louder until you turn it off. The company explains, “The gentle light tells your body that it is morning，so it stops producing a chemical that helps you sleep. ” 1. The smart schoolbag has been invented by ____.

Having a special，uncommon mind often goes hand in hand with unusual acts. Nikola Tesla is known for many inventions. One is the alternating­current(AC) electricity. While inventing it，Tesla was good at keeping things in mind，because he used picture thinking and imagined every step in his mind before even picking up a pencil. Tesla said he wanted to do it because of his mother，who invented small electrical machines when he was a child. In his later years，Tesla had many strange habits. He slept only two hours every night and dined at exactly 8: 10 p. m. After dinner, he'd often work until 3 a. m. Before bed，Tesla curled(卷曲)each foot 100 times，saying it was good for his brain. Another scientist encouraged by his mother was Albert Einstein，though what he got from his mother was a love of music. In fact，Einstein often played music on the piano and the violin to help him brainstorm. Einstein's achievements include the most famous equation(方程式) E ＝ mc2 and his theory of relativity. However，thanks to his wild hair，he is also well­known for the looks of a “mad scientist” and you can tell that he had some interesting quirks(奇怪的个性). For example，he had a strong dislike of wearing socks. And Einstein was so withdrawn(内向的)as a boy that he couldn't speak until he was three. Sometimes，the smartest of us are also the strangest. That quiet child in the corner may be the next Tesla or Einstein one day. 9. How did Tesla remember things? A. By taking things down. B. By thinking in pictures. C. By drawing mind­maps. D. By reading aloud. 10. Which of the following statements is TRUE according to the passage? A. Tesla hated having to wear socks. B. Tesla did some foot exercises before bed. C. Einstein was outgoing when he was a child. D. Einstein was also famous for his hair color. 11. What did Tesla and Einstein have in common? A. They both had great inventions of electricity. B. They both took up inventing because of their mothers. C. They both thought and acted in unusual ways. D They both played the piano for better working. 12. What does the writer mainly want to tell us about? A. The special things about well­known scientists. B. The living habits of smart people. C. The mothers of Tesla and Einstein. D. The inventions of great people. D How do we know the time? A clock，a watch or a mobile phone can help us. However，many years ago there were no clocks and knowing the time was not so easy. Over the centuries people have developed different ways of telling the time. About 5，500 years ago，the Egyptians invented the sun clock. This was a tall stone building. Its shadow(影子) showed the movement of the sun. So people were able to know midday. The Egyptians made a sundial (日晷) about 3，500 years ago. It was smaller than the sun clock and could let people know the time for half a day. On rainy days or at night it was impossible to tell the time with a sun clock or a sundial. Water clocks were the first clocks not to use the sun. The idea is simple. Water flows(流动) from one bottle to another. When the water reaches a certain level，it shows the hours. The Egyptians used water clocks about 3，400 years ago. These clocks were popular in the Middle East and China. But they failed to make people know the exact time. In the 13th century，the mechanical clock was invented. This was more exact，but it was expensive to make one. Over the next few centuries it was developed. For example，springs(发条) were added around 1500. This enabled people to get the correct time and allowed clocks to be smaller. In 1927，the first quartz clock was developed. Clocks became cheaper to build. It was also cheaper for ordinary people to own a clock. People began depending on them more and more to run business，markets and so on. More recently，in 1956，came the digital clock. And nowadays satellites send our mobile phones the time to the exact second. There have been a lot of ways in timekeeping. Clocks are always changing but some things never change. Many of us still have trouble getting out of bed on time and not being late for school or work. 13. According to the passage，we can't use ____ to tell the time on a rainy day. A. the water clock B. the sun clock C. the digital clock D. the mechanical clock 14. How many kinds of clocks are mentioned in the passage? A. Four. B. Five. C. Six. D. Seven. 15. Which of the following shows the structure(结构) of the passage? (①＝Paragraph 1，②＝Paragraph 2，…) 16. What does the passage mainly talk about? A. The importance of time. B. The development of timekeeping. C. The inventions of clocks. D. The history of a digital clock. 第二节 阅读短文，从方框内所给的选项中选出可以填入空白处的最佳选项，其中有一个多余的选项。,[科学素质·科技产品体验]) Shanghai General Hospital signed an agreement with China Mobile Shanghai Branch (分部) to build a 5G technology treatment center. “17. ________，”said Dr. Zheng Xingdong，president of Shanghai General Hospital.

Their inventions have an important influence on the world. Here are two of the inventors. Alexander Graham Bell invented one of the most important inventions of all time. That was the telephone. Today the telephone is still widely used in our daily life. He lived from 1847 to 1922. He lived first in Edinburgh，Scotland，and then in Canada and finally in the United States. He invented the first telephone in 1876. Another similar invention of Bell's was the photophone. This device(设备) made it possible for voices or sounds to be sent using light. Bell was especially interested in inventions which help the education of the people who are unable to speak or hear. Thomas Alva Edison was an American inventor who lived from 1847 to 1931. He invented over 2，000 inventions in his lifetime. Two of the most important inventions were the electric light bulb and the phonograph. The phonograph was the first device to record sound. Edison set up a laboratory(实验室) in New Jersey in 1876. He made a large amount of money by selling one of his earlier inventions— the telegraph. He also invented an item that continues to be used to this day. That was the electric storage battery(蓄电池). 41.
