Dictionary

I think, dictionary is very important for us .In primary school ,our teacher already have taught us how to use dictionary .After that ,our book were appeared a lot of strange words .So that we must be use it .
After entering the senior middle school ,mostly students already have used dictionary.In university,electronic dictionary become necessities.
Dictionary has two types ,book and electronic dictionary .Electronic dictionary ,it is many to be divided ,for example ,English to Chinese ,Chinese to English ,Japaness to Chinese,and so on .
I think dictionary will be more and more important.
