    English is one of the important subjects in our studies．But it is not easy to learn it well．

    Everyone wants to remember all the new words and expressions．Everyone wants to use them correctly．Of course，we cannot expect to do this in a few months．We must read and write every day．We must study grammar．And we must practice more．

    Everyone can make mistakes when speaking．So we needn’t worry about it．As the old saying goes．“Practice makes perfect．”

    Everyone can learn English well if he studies hard enough．
