我想发明一种高科技文具盒，文具盒的门可以自动开门儿，而且还可以把铅笔自动送出来，橡皮都可以自动出来呢，它还可以自动帮你削铅笔呢，你只要摁一下开关它就可以帮你削铅笔，是不是很神奇呀。
I want to invent a kind of high-tech stationery box. The door of the stationery box can open automatically, and the pencil can be sent out automatically. The rubber can come out automatically. It can also help you sharpen the pencil automatically. If you press the switch, it can help you sharpen the pencil. Isn't it amazing.
