production of english be-passive by farsi-speaking efl learners: a cognitive-construction grammar approach

english passive has always been regarded as a challenge by farsi-speaking efl learners. despite the presence of many linguistic and pedagogical approaches in studying and teaching english passive, there still appears to be a pedagogical gap facing farsi-speaking efl learners dealing with this construction. taking up the cognitive-construction grammar perspective, the present article aims to investigate some aspects of the farsi learners' errors emerged in forming english be-passive. in the present article, while investigating the linguistic behavior of farsi-speaking efl learners in forming english be-passive through designing and implementing a writing experiment on a group of 30 subjects of intermediate proficiency level, we found that subjects show a variety of performance errors which can be analyzed in terms of cognitive-construction grammar approach, and consequently, several suggestions can be put forth for teaching english be-passive to farsi-speaking efl learners.
