Dictionaris are of great use and help in learnig English.They are just like teachers when we need help.When we meet new words,just turn to them for help.They will never refuse to offer great to us.They can tell us how a word is pronounced,what it means and how it is used.Some people even like to use electronic dictionaries.Because electronic dictionaries can not only tell us the sound and meaning of words, they can also pronounce the words out like real people,they are easy to carry and use.
　　We have to use dictionaries properly and we needn’t look up every word in the dictionaries.Sometimes we havt to guess the meaning out according to the context.
