Recently,more and more students use electronic dictionary rather than papery dictionary when they need to look up words.
The biggest advantage of using electronic dictionary is convenience.Also,they can provide us with the exact pronunciation of the words.Besides,they also provide many other functions.For example,they can be used as calculator,which makes us save money from buying another one.
But,needless to say,the disadvantages can be easily found.Obviously,like other electronic equipments,they are harmful to our eyes.What`s more,they have bad influence in protecting our environment.
