Nowadays many people use tele
-dictionaries to look up words.I know it is very convenient . We can put it in the bag or in our pocket and we can carry it anywhere.
In addition, many tele-dictionaries have many other effects.For exaple, we can take time schedule in it,store some important messages in it ,such as friends' adresses, E-mail, telephone numbers.
On the other hand, maybe we will depend on the tele-dictionary.That is to say, when we meet a new word in reading,we will refer to it without thinking about it ourselves.So it can make us lazy.
