If I am a designer, I also want to design an eraser for my classmates. This eraser is the active key in the upper right corner of the keyboard. Students write with a pencil, and sometimes they make mistakes. You can use it to wipe. Even if you use a pen, ballpoint pen or gel pen to write typos, you can also use it to wipe them, which will be clean and won't rub books. In this way, students will not often use correction fluid to make books yellow and white, which is not good-looking, and students will also be prevented from tearing books with glue. When finished, put it back on the keyboard and suck it. It's not easy to lose it.
If I were a designer, I would design a chair for my classmates in summer. This chair is cool to sit on. Because there is air conditioning under the chair, it can also be used as a heater in winter.
Children, what I invented is good? Do you like it?
Are you satisfied with my answer? Hope to adopt, thank you!
