摘要:Listening is an active process in which a listener selects and interprets information which comes from auditory and visual clues in order to define what is going on and what the speakers are trying to express. It involves both linguistic and non-linguistic knowledge. Linguistic knowledge relates to knowledge of phonology, lexis, syntax, semantics, discourse structure, pragmatics and sociolinguistics, whereas non-linguistic refers to knowledge of the topic, the context and general knowledge about the world and how it works. This article investigates the effect of text familiarity on listening comprehension. The paper focuses on two main issues. First, it investigates the effect of text familiarity on listening comprehension of Iranian EFL learners. Second, it investigates the influence of text familiarity on some aspects of the language. Sixty students who were studying in English Translation at the Islamic Azad University of Lahijan, Iran participated in this study. After comparing the pretest and posttest scores, it was indicated that Iranian EFL learners got substantially higher scores after the treatment. The findings showed that text familiarity has a considerable impact on listening comprehension of Iranian EFL learners.
