If I were an inventor, I would invent a dust-free book, a waterproof and fireproof book. This kind of book is powered by solar energy, which saves energy and does not destroy the air. It is as small as my palm and has many functions. This book can watch news, listen to music, read poems, read texts, etc ... It is improved by using advanced e-books. My book has a buttON, and there is a letter "on" on the cover of the book. This is its switch. After opening, the book will automatically open with the music and the concert will stop. At this time it will become a touch screen as big as a newspaper. You can drag and click with your finger. It will adjust the brightness and contrast according to your sitting posture. With a finger, a table of contents will appear with100,000 titles. Click on the title, then browse, find the content and clips you want to see, and press the play button to read.
This book can listen to music. As long as you open the book and press the music playing mode, there will be more than a dozen programs on the screen, such as free song ordering, semi-automatic playing and full-automatic playing. Click on the free song-ordering template, you can order songs at will, breathe out the song name into the microphone and press the play template to feel the sound of nature. You can read the news in this book. Just open the book and press the template of the news player, and the subtitles of the world news will appear on the screen. Then, you can view the news by selecting the initial appearance, country, region and date of the template. You can see this news whenever and wherever. If I were an inventor, I would invent a multifunctional book.
