Together with the development of technology, the assistant devices which help people in studying such as TV, computers, smartphone, etc are of higher quality day by day. It seems that students cannot live without them as they provide them a great deal sources of information, help them keep in touch with their friends and supply with a lot of kinds of entertainment. However, dating back to 20 years ago, they are completely unknown to the students. Without the help of modern devices, they might find it difficult to deal with homework, have nothing to find information for their project but they were still excellent due to their self-study and ambition. In my book, the radical changes have both negative sides and advantages; nevertheless, it would be still good if they didn't exist.
