Mọi người sửa giùm em bài này ạ, em cảm ơn.

Internet is a support tool helps a lot for people now but in twenty years ago, it's very difficult to use the internet because internet is very expensive. The internet is used for entertainment, messaging, searching data,... Almost students twenty years ago could not use the internet for their studies so it is very difficult for students to find information. For example: Students twenty years ago must go to the library to find learning materials but now, students can search materials by phone easily. Since the internet, students learning has been more and more favourable to help student achieve high results.
