光阴似箭，日月如梭，一转眼就到了10年后。这时，我已经成为了一个举世闻名的大发明家。最近，我成功发明了世界上第一个“多功能书包”。
Time flies like an arrow, the sun and moon shuttle like a shuttle, and in the blink of an eye, 10 years have passed. At this point, I had become a world-renowned inventor. Recently, I successfully invented the world's first 'multifunctional backpack'.
虽然多功能书包看起来和普通书包没什么明显的差别，但你仔细观察下，就能发现它有许多地方与普通书包不一样。比如：多功能书包是用了一种“特制的橡胶材料做的，比普通书包轻一百倍，还有两条结实的背带，很多按钮组合而成。不用我说，大家都知道学生每天上学都要背着重重的书包，不仅十分疲倦，而且压迫了脊柱，压完了背。多功能书包解决了这个问题，你只要按红色按钮，它就会多出两条腿，自己走去学校。出自 wwW.zuoWEnBA.nEt
Although the multifunctional backpack may not look significantly different from a regular backpack, upon closer inspection, you can notice that there are many differences between it and a regular backpack. For example, a multifunctional backpack is made of a special rubber material that is 100 times lighter than a regular backpack, with two sturdy straps and many buttons combined. It goes without saying that students have to carry heavy backpacks to school every day, which not only makes them very tired, but also compresses their spine. The multifunctional backpack solves this problem, as long as you press the red button, it will have two extra legs and walk to school on its own.
有时，有些学生总是忘记带学习用品，可是有了多功能书包，就不用担心这个问题。只要按动蓝色按钮，它就会自动识别有什么学习用品没带，比如：语文书没带，它识别出来后，它会提醒你：“主人，你语文书没带。”但如果全都带了，它就会亮绿灯。
Sometimes, some students always forget to bring their study supplies, but with a multifunctional backpack, they don't have to worry about this problem. As long as you press the blue button, it will automatically recognize what learning supplies you haven't brought. For example, if you haven't brought your Chinese book, it will remind you, "Master, you haven't brought your Chinese book." But if you have brought all of them, it will light up green.
多功能书包还有按摩功能，有的时候，有些学生连续上几节课，就感觉身体十分酸痛，很累，此时此刻，你只需要按下书包上的绿色按钮，然后靠在书包上，它就会自动给你来一次五星级的全身按摩，让你全身放松。
The multifunctional backpack also has a massage function. Sometimes, some students feel very sore and tired after attending several classes in a row. At this moment, you just need to press the green button on the backpack and lean against it. It will automatically give you a five-star full body massage to relax your whole body.
怎么样，我发明的多功能书包神奇吧？让我们一起认真学习，攀登科学高峰，用科技研究来帮助发明更多功能的书包，造福学生吧！
How about it, isn't the multifunctional backpack I invented magical? Let's study seriously together, climb the peak of science, use technological research to help invent more functional backpacks, and benefit students!
