An opinion esssay: Books and technology Nowadays, more and more schools replace books by computers and tablets. We might not can stop the digital trend growing up. It's not the only way we learn knowledge from books. There are some advantages to changing books to tablets. Firstly, tablets provide a new way to interact with the students. A lot of applications are designed for education. It's a good choice to learn new things. Secondly, tablets are extremely light weight than books. It only needs one small bag to carry. Thirdly, tablets are more economic than books. Transferring e books is always cheaper than buying realistic books,although a device is more expensive than a book. A tablet also can save the room of placing books. Even though tablets have a lot of advantages, books can not be completely replaced by devices. Firstly, Students can read book longer than watch computer's screen and tablets. Eyes will be tired when use these devices too long. Secondly, Books make students concentrated. Technology devices can easily make students lost their concentrations. The games, application, and notifications can draw student's attentions. In spite of advantages of devices, there are still some reasons that can not be replaced all the books. I think they have to exist at the same time. Both of them can not replace another one.
