With rapid progress of science and technology ,our life has changed a lot .I think the school life in the future will be quite different from now . First I think the students will not have to use the text books at school instead ,they will get more knowledge on the Internet . Second they won't have to write their homework instead ,they will finish it by sending their teachers emails. Finally, the teachers will not write anything on the blackboard ,instead they will also use the computers to teach.
