To solve this problem, a 13-year-old middle school student Zhang from Shenzhen invented a smart robot and he got first prize in the 20th Guangdong Provincial Children's Invention Awards（奖项）. His parents are so proud of him. 15 This robot can collect homework in a short time without making any mistakes. It uses radio frequency identification（RFID，射频识别） technology—a reader and a special tag（标签） that can share information without touching each other. This way, it can help find and know what it is looking for. Each student's notebook has a special RFID tag with their name and the subject. Students only need to place their notebooks on the robot, and the machine “sees” the notebook, reads its tag and takes it out of the name list. Teachers can check who hasn't handed in homework by connecting their phones with the robot through Wi-Fi. 16 Many teachers speak highly of the robot after using it and they think Zhang will create more useful AI tools to make life easier. His parents will continue to support him. Inspired by the words, Zhang dreams of becoming a scientist when he grows up. “I have tried making model airplanes and other scientific and creative projects. Inventing has brought me joy and happiness,” he said. 17 1. What kind of award did Zhang win?( ) C A. Art. B. Music. C. Invention. 2.

When it first started, it was just something beautiful sewn（缝上） onto your clothes. What is more important than the button is the buttonhole. About 3,000 years later, someone finally invented the buttonhole, and buttons were suddenly useful. 21 Before buttons, clothes were bigger—they had no fixed shapes. Because of the buttonhole, the fashion（时尚） moved closer to the body when we discovered uses for the button. It was the very way to make clothes fit well for the body. People feel safer because the button is never going to open. The size of the button depends on its use. Shirt buttons are generally small, and they are close to each other, while coat buttons are larger and farther apart. For example, the standard（标准） buttons of men's shirts are 10.16 mm and of suit jackets are 20.32 mm. 22 In modern clothing and fashion design, buttons are mostly made of plastic（塑料） but they are also made of metal（金属） or wood. Buttons can also be used on wallets and bags. They can be shown as examples of works of art. A button can be used for a long time. It's one of the most lasting designs in history, because it really works to make people feel safer. Zippers easily break and are hard to fix. However, if a button breaks, you just need to sew another on. And you can sew more buttons if needed. 23 The pattern of a button hasn't changed much since the Middle Ages. It's not only one of the most useful inventions, but it plays an important role in the development of clothes. Up to now, we can still see its influence on the clothes design. If you're wearing the clothes with buttons, take a look at the position（位置） of buttons on it. If you're a man, the buttons would likely be on the right side, but for a woman, the buttons are usually found on the left. 24 1. When were buttons suddenly useful?( ) B A. Before buttonholes appeared. B. After buttonholes were invented. C. When buttons appeared in 2,000 BC. 25 2. According to Paragraphs 2 & 3, which of the following is true?( ) A A. Suit jacket buttons are bigger than shirt buttons. B. Coat buttons are close to each other. C. Coat buttons fit well for the body. 3. Which of the following is not mentioned to make buttons?( ) B A. Metal. B. Glass. C. Plastic. 26 4. What can we know from the text?( ) A A. The influence of buttons never disappears. B. Buttons are not so easy to fix as zippers. C. Buttons make clothes out of date. 5. 文章出处题 In which part of a website would you most probably read the text?( ) C A. Energy. B. Travel. C.
