What is the main type of the text Young Inventors? A. A story about two young inventors’ life and inventions B. A notice about invention competitions C. A poem about great people D. A science report about TV machines √ Young Inventors You may think that all inventors are adults with rich experience and university degrees, but you would be wrong. In fact, many famous inventions have been created by teenagers just like you. Helping the blind to read At the age of three, Louis Braille became blind as a result of an accident. At a school for the blind, he was taught to read using books with raised letters. Blind people would run their fingers over the letters and guess their shapes. However, sometimes it was confusing because letters like “Q” and “O” were very similar, and they also took up too much space on a page. 你或许认为……，但你错了。 现在完成时被动语态 adj. 凸起的 To solve these problems, a system was invented where letters were replaced with a code of raised dots. However, this new method was still too slow and difficult. At the age of 15, Braille made important improvements to the raised dot system. He made the code simpler and reduced the number of raised dots. Braille’s system was incredibly successful and is still used today around the world. Bringing entertainment to our homes Philo Farnsworth was a teenager when he read about the problem of creating an electronic television in a science magazine and became interested in it. One day, while he was working on a farm, he noticed the straight rows of crops, and it gave him an idea. Perhaps an image could be broken down into lines, changed into electronic signals, and then sent through the airwaves. 对…… 作出重要改进 /ɪnˈkredəbli/  adv. 极其；非常；难以置信地 把…… 分解成 For years, Farnsworth worked to develop his idea, but he faced many challenges along the way. Many people did not believe his idea would work, and he found it difficult to get money to pay for his research. However, he never gave up. When he was 21, he eventually succeeded in sending a simple image using his invention.This breakthrough was an important step in creating the modern televisions that we use for entertainment today. These stories show that with a passion for solving problems, anyone can make a difference in the world, no matter how old they are. So, if you have an idea that you believe in, do not be afraid to go for it. Who knows? You may just be the next Louis Braille or Philo Farnsworth. 如果你有…… 的想法，不要害怕去…… /ɪˈventʃuəli/ adv. 最终；终于 /ˌentəˈteɪnmənt/ n. 娱乐；消遣 1 Read the text and complete the table about the young inventors and their inventions.
