Nowadays, the majority of students prefer to using electronic dictionaries because they considered electronic dictionaries smart and convenient to carry. Besides, it has many other potential function, such as taking photos, calculating, playing music, getting on line and play games. However, others hold total different views, saying printed dictionaries are equipped with a large vocabulary. And more detailed examples are given when the electronic dictionaries provide limited information. However, the printed dictionaries cost much less than electronic ones. Personally, I prefer electronic dictionary because it not only serve as a dictionary but also a calendar, media player, camera and timekeeper.
