A successful language learner should be able to use the language he has learned to
communicate efficiently with those who speak the same language,to understand most
of the stuffs printed in the language.What's more,he should also possess the ability to
write down whatever he wants to in the language.In one word,he should use the lang-uage as naturally as a native speaker does.
No one can reap where he hasn't sown.To be a successful language earner is not
an exception.To be that level.you have to sacrifice a lot of leisure time to practice the language,including speaking,listening,reading and writing.In addition, you have to
remember a great many vocabularies,including their spelling and their usage.And the
most important of all,you must do all above persistently.Practice makes perfect yet only consistent practice makes it make sense.
