Morpho-syntactic patterns device encompasses a subcategory of the cohesive devices that assists hearers to have an adequate mental representation for understanding speech. This article investigates the morpho-syntactic patterns employed in some Persian live sport radio and TV programs adapting Dooley and Levinsohn’s theoretical and analytical framework. The research data includes around 30,000 words extracted from 20 live sport radio and TV recorded programs. The morpho-syntactic patterns functionality is presented via comparing their frequency using descriptive statistics. The t-test is run to evaluate whether the differences in the utilization of morpho-syntactic patterns used in live radio and TV talks is significant or not. The results show that such patterns in Persian can be studied in the same way as Dooley and Levinsohn’s perspective, among which consistency of inflectional categories receives the most frequency while echoic utterances do the least. The consistency of inflectional categories catches a meaningful difference between its applications in the research data. Furthermore, there are not significant differences between the application of echoic utterances and discourse-pragmatic structuring in the corpora. Finally, morpho-syntactic patterns device, generally speaking, is reported as not having any significant relation in its applications in Persian live radio and TV talks under study.

How language teachers talk is a key factor in organizing and facilitating learning specifically in language classrooms where the medium of instruction is also the subject matter. This study aimed to examine the extent and ways of teacher talk adaptation to students’ proficiency levels in the Iranian EFL context. Two EFL teachers who were teaching three different proficiency levels were observed and recorded. They were also interviewed to see if they would make any conscious effort to adapt to their students’ proficiency level. Furthermore, the students of the same classes were interviewed for the comprehensibility of their teachers’ talk. Data were analyzed for four major areas of adaptation including speech rate, vocabulary, syntax, and discourse. The results showed that teachers’ adaptation to students’ level does happen clearly for elementary students, but the adaptation boundary between the intermediate and advanced levels is fuzzy. The findings also indicated that in spite of what they think, teachers’ talk is not tuned to elementary students’ understanding.

Task difficulty across different macro-genres continues to remain among less attended areas in second language development studies. This study examined the correlation between task difficulty across the descriptive, narrative, argumentative, and expository macro-genres. The three components of task difficulty (i.e., code complexity, cognitive complexity, and communicative stress) were also compared in the four macro-genres. The design included the administration of short reading texts with comparable length and readability indices based on the four macro-genres followed by task difficulty questionnaire. The macro-genre-based reading textsalong with the task difficulty questionnaire were administered to 50 EFL students in the University ofLorestan, Iran. Task difficulty questionnaire explored the learners’ perceptions of task difficulty in the code complexity, cognitive complexity, and communicative stress domains. The results revealed that there were no significant differences among the task difficulty components in the four macro-genre-based text types. The findings also showed that there was no significant correlation between task difficulty of each macro-genre with those of the other genres except thoseofthe narrative and expository genres.The findings hold implications for the use of macro-genres with different task difficulty indices in task-oriented programs, teacher training, and testing.

As a fascinating and colorful part of English language, idioms highly affect fluency, but they are quite difficult to teach and learn, and they have often been neglected particularly in ESL/EFL settings. Considering the large number of English idioms, corpus linguistics can be of great benefit in prioritizing materials in language classrooms based on the frequency information. Accordingly, the present corpus-based study aimed at identifying the most frequent idioms in English language by analyzing the data coming from the Corpus of Contemporary American English (COCA), composed of more than 520 million words. The study involved writing a special script using Hypertext Preprocessor (PHP) language which resulted in the development of five idiom lists, each containing 50 most frequently used idioms in each one of the five genres in COCA including academic, fiction, spoken, newspaper, and magazine along with their frequency of occurrences. Comparison was then made across the mentioned five genres. It was found that the spoken genre included more idioms whereas the academic genre was the least idiomatic. Furthermore, various levels of overlap was found among different genres. The least and the highest levels of overlap was found between the academic and fiction genres and between the magazine and newspaper genres respectively. The academic genre had more overlap with the newspaper and magazine genres. The findings can benefit EFL materials developers, teachers, and learners in recognizing and including frequently-used authentic idioms in language classrooms and textbooks.
