Every school day， we use schoolbags to carry all of our things to school. They are a big part of our lives. But have you ever thought about the history of the schoolbag？

In the Han Dynasty， students in old-style private schools used bamboo boxes to carry books to school. People consider the bamboo boxes to be the earliest schoolbags. There were usually two or three layers in the box. Kids put different things like books， brushes， ink stones and paper in the boxes.

每個上學日，我們都背著書包，把我們的學習必需品帶到學校。書包是我們生活中的重要部分。但是你知道書包的歷史嗎？

漢朝時，舊式私塾的學生使用竹箱將書背到學校。竹箱被視為最早的書包。箱子通常被分成兩層或三層，孩子將書籍、毛筆、硯、紙等各種東西放進箱子里。

Hundreds of years later， people developed a new kind of schoolbag called budai. Budai was lighter than the bamboo box. With the founding of the Peoples Republic of China， military rucksacks became popular. Many people carried them when they were in school. Ask your grandparents or parents about these bags. Maybe they can tell you about their experiences of carrying them when they were in school.

A new style of schoolbags has appeared in recent years. Many of them have colorful and fashionable designs on them， such as pictures of cartoons or pop stars. And they are more comfortable to use.

Schoolbags are still changing. Can you imagine what future schoolbags will be like？

幾百年后，人們制造出了一種新的書包，叫作“布袋”。布袋比竹箱輕。中華人民共和國成立以后，軍用帆布挎包大受歡迎。很多學生都背帆布挎包。你可以問一下你的爺爺奶奶或是爸爸媽媽關于帆布挎包的事情?；蛟S他們會告訴你，他們在學校背帆布挎包的經歷呢。

近年來，書包又有了新的樣式。許多書包色彩豐富、設計時尚，有的書包還印有卡通人物或是明星畫像。而且，它們背起來更舒適。

書包還在變化著。你能想象出未來書包的樣子嗎？
