Good morning, boys and girls! I'm Li Hua. I'm very glad to speak here and I’d like to talk about schoolbags. I still remember my first schoolbag that was a birthday gift from my aunt. It was a beautiful large blue schoolbag. I liked it very much, because it was so large that it could hold my books, pens, notebooks and so on. Now, with the development of the science and technology, there are more and more functions and styles of schoolbags. I hope my schoolbag in the future is much smaller and more useful. That’s all. Thank you!
