The present research addressed the prosodic realization of global and local text structure and content in the spoken discourse data produced by Persian EFL learners. Two newspaper articles were analyzed using Rhetorical Structure Theory. Based on these analyses, the global structure in terms of hierarchical level, the local structure in terms of the relative importance of text segments and the rhetorical relations between text segments were identified. The texts were read aloud by 18 high-proficient Persian learners of English. We measured pause durations preceding segments, F0-maxima (as a correlate of pitch range) and speech rates of the segments. Results suggested that speakers give prosodic indications about hierarchical level by means of variations in pause duration but not pitch range or speech rate. Furthermore, it was found that speakers articulate causally related segments with shorter in between pauses and at faster rate than non-causally related segments. However, they did not vary any of the prosodic measures to distinguish between important vs. unimportant segments. Overall, the results suggest that (1) variations in pause duration and speech rate are not used systematically by Persian EFL speakers as fully structured cuing devices to indicate organization of spoken discourse, importance of sentences and meaning relations between sentences; (2) pitch change structuring as a cue to discourse prosodic prominence is completely absent in Persian learners' text production. The results are not consistent with earlier findings of prosodic realization of text structure and content in English native speakers' discourse data, but are in line with those obtained for non-native spoken discourse.

The purpose of this paper was to investigate the authenticity of IELTS academic tests. Bachman and Palmer (1996, p. 23) define authenticity as “the degree of correspondence of the characteristics of a given language test task to the features of a target language task”. Authenticity is then an important aspect of testing since it describes the relationship between the test and the real world. The participants of this study included 80 Iranian IELTS test takers who took IELTS academic test in 2014 and 2015, and 100 lecturers of university and IELTS teachers. Twenty IELTS test takers also were interviewed to collect the required qualitative part of data. The data were gathered through a semi-structured interview and authenticity checklist. Descriptive statistics used to analyze the collected data. The findings of the study showed that IELTS academic tests are not authentic in terms of tone, format, channel, form and scope of interaction. Moreover, mostly the interviewees stated that answering the items in IELTS academic test requires specific techniques and test takers can not succeed without mastering these techniques.
