Chọn một phương tiện không thích hợp với 20 năm trước và viết một miêu tả ngắn về việc làm sao các học sinh trong quá khứ học mà không cần phương tiện này

Twenty years ago, students weren't able to enjoy the Internet in their studies. It took a lot of time, energy and even money to do projects or assignment. If they were asked to write down the assignment, they would have to prepare it for some days. They had to go to the library to look for books on the topic and read them. Then they handwrote useful information for their assignment. They also met old people and talked about the past to get information. At home, they had to handwrite their assignment on a piece of paper for drafting.
