In Year 2050,there's no school at all.Students study at home using devices to connect with teacher and classmates for inter-active study.There are LED screens,video and multimedia equipments for their study at home.The students are not only local but international.They choose any class and subject they like to study and join before the class starts.There's no border of countries and knowledge and the world is getting closer and closer.请解释下内容的意思，谢谢在2005年已經沒有所謂的學校了. 學生在家學習和老師及同學使用裝置連線互動學習.家裡有LED螢幕, 視訊以及多媒體設備供學習之用.學生並非全來自本地也有國際學生.他們選擇自己喜歡的科目並在開課前加入.已經沒有所謂的國家與知識的界線, 這個世界已經更加的密切.
