01?A.Howtobeasuccessfullanguagelearner?

"Learningalanguageiseasy,evenachildcandoit!”

Mostadultswhoarelearningasecondlanguagewoulddisagreewith

thisstatement.Forthem,learningalanguageisaverydifficulttask.They

needhundredsofhoursofstudyandpractice,andeventhiswillnot

guaranteesuccessforeveryadultlanguagelearner.

Languagelearningisdifferentfromotherkindsoflearning.Some

peoplewhoareveryintelligentandsuccessfulintheirfieldsfindit

difficulttosucceedinlanguagelearning.Conversely,somepeoplewho

aresuccessfullanguagelearnersfinditdifficulttosucceedinotherfields.

Languageteachersoftenofferadvicetolanguagelearners:uReadas

muchasyoucaninthenewlanguage."Practicespeakingthelanguage

everyday.”“Livewithpeoplewhospeakthelanguage.v"Don't

translate-trytothinkinthenewlanguage.”"Learnasachildwouldlearn;

playwiththelanguage.,,

Butwhatdoesasuccessfullanguagelearnerdo?Languagelearning

researchshowsthatsuccessfullanguagelearnersaresimilarinmany

ways.

Firstofall,successfullanguagelearnersareindependentlearners.

Theydonotdependonthebookortheteacher;theydiscovertheirown

waytolearnthelanguage.Insteadofwaitingfortheteachertoexplain,

theytrytofindthepatternsandtherulesforthemselves.Theyaregood

guesserswholookforcluesandformtheirownconclusions.Whenthey

guesswrong,theyguessagain.Theytrytolearnfromtheirmistakes.

Successfullanguagelearningisactivelearning.Therefore,

successfullearnersdonotwaitforachancetousethelanguage;theylook

forsuchachance.Theyfindpeoplewhospeakthelanguageandtheyask

thesepeopletocorrectthemwhentheymakeamistake.Theywilltry

anythingtocommunicate.Theyarenotafraidtorepeatwhattheyhearor

tosaystrangethings;theyarewillingtomakemistakesandtryagain.

Whencommunicationisdifficult,theycanacceptinformationthatis

inexactorincomplete.Itismoreimportantforthemtolearntothinkin

thelanguagethantoknowthemeaningofeveryword.

Finally,successfullanguagelearnersarelearnerswithapurpose.

Theywanttolearnthelanguagebecausetheyareinterestedinthe

andpuiposefully.Ontheotherhand,ifyourlanguagelearninghasbeen
