Successful Language Learners1. Some people seem to have a knack for learning languages.They can pick up new vocabulary, master rules or grammar,and learn to write in the new language more quickly than others.They do not seem to be any more intelligent than others,so what makes language learning so much eas- ier for them?Perhaps if we take a close look at these successful language learners,we may dis- cover a few of the techniques which make language learning easier for them.2. First of all,successful language learners are independent learners.They do not depend on the book or the teacher;they discover their own way to learn the language.Instead of waiting for the teacher to explain,they try to find the patterns and the rules for themselves.They are good guess-ers who look for clues and form their own conclusions.When they guess wrong,they guess again. They try to learn from mistakes.3. Successful language learning is active learning. Therefore,successful learners do not wait for a chance to use the language;they look for such a chance.They find people who speak the lan-guage and they ask these people to correct them when they make a mistake.They will try anything to communicate .They are not afraid to repeat what they hear or to say strange things;they are willing to make mistakes and try again .When communication is difficult,they can accept information that is inexact or incomplete.It is more important for them to learn to think in the language than to know the meaning of every word.4. Finally,successful language learners are learners with a purpose.They want to learn the language because they are interested in the language and the people who speak it.It is necessary for them to learn the language in order to communicate with these people and to learn from them. They find it easy to practice using the language regularly because they want to learn with it.5. What kind of language learner are you?If you are a successful language learner,you have probably been learning independently,actively,and purposefully. On the other hand,if your language learning has been less than successful,you might as well try some of the techniques outlined above. Active language learners seize every opportunity______.A: to discover sentence patterns and grammatical rulesB: to expand vocabularyC: to use the target languageD: to encourage unsuccessful language learners to learn independently,actively and purposefullyE: from cluesF: to say strange things

Materials and Tools for Language Learning
① The range of materials and tools available to help you with your language studies is huge, from dictionaries to language courses. All of them can help you in different ways, and the appropriate use of these materials and courses will make your language learning much easier and more effective.
② Possibly the most useful tools there are for learning a language are dictionaries. Dictionaries come in a number of formats including bilingual, monolingual, illustrated, electronic and online. Bilingual dictionaries are perhaps the most useful ones for beginners and intermediate learners, while monolingual dictionaries, which are designed for native speakers, are also useful for advanced learners. Pocket dictionaries are good for quick reference and easy to carry around. Larger dictionaries are better if you want more definitions, examples of usage, and information about pronunciation, and grammar. Electronic dictionaries are available as handheld units, or as software. Handheld ones are portable, easy and quick to search, and often provide other functions, such as, text-to-speech, voice recognition and speech synthesis organizers, address books. They tend to be rather expensive though. Software dictionaries offer many of the same functions, and can be used on computers, and mobile phones.
③ The traditional courses tend to consist of textbooks containing dialogues, exercises, notes on grammar, and maybe cultural information. Accompanying cassettes, CDs and/or mp3s are often available. Most such courses are intended for complete beginners or people with only minimal knowledge of the language. Intermediate and advanced-level courses are available for some of the popular languages, such as French, German, Italian and Spanish.
④ Audio courses usually consist solely of cassettes or CDs, though some may also include a limited amount of printed material. All dialogues, exercises, instructions and explanations are recorded and the focus of these courses is teaching you to understand and speak the languages. They are very good at teaching you authentic pronunciation and a manageable amount of vocabulary.
⑤ Various computer-aided courses are available on CD-ROMs and DVDs. Each course is different but they generally include dialogues, audio, exercises and tests. Some also include phrasebooks, dictionaries, videos, games and provide online and/or telephone support.
Larger dictionaries will provide the learners with（）A、more definitions, examples of usage, and information about pronunciation, and grammarB、authentic pronunciation and a manageable amount of vocabularyC、phrasebooks, dictionaries, videos, games and provide online and/or telephone supportD、from dictionaries to language coursesE、in a much easier and more effective wayF、beginners or people with only a little knowledge of the language
