Advertisement has long been used as a tool for informing and attracting audiences in different ways. This study aims at investigating the linguistic tools of advertisement in Persian on the basis of Halliday’s systemic-functional grammar theory. The data of this study were gathered from written and verbal commercial advertisements which were recorded and rewritten in order to investigate verbal groups in the sentences in terms of process and function types and subsequently compare the two bodies. The results showed that material and relational processes had highest frequency in Persian language in terms of ideational metafunction. From the interpersonal metafunction perspective, information function was frequent in most cases. Regarding these factors, there was no significant difference between verbal and written bodies.

Evolution of languages has always been of interest to linguists. In this paper we study the natural progress of the syllable structure from Old Persian (O.P) to Middle Persian (Mi.P) and up to the Modern Persian (Mo.P). For this purpose all the words containing consonant sequences are collected from specific sources of each of these languages, and then analysed according to the syllabification principles. Pulgram (1970) distinguishes three principles for this matter which is stated in Hyman (2003:279).The first one, is the maximum open syllable principle, the second, the minimum coda and maximum onset principle and the last one is the irregular coda principle. In addition , to find the syllable structure of the words, phonological rules are also applied. Greenberg (1978) suggests a number of rules specifying the collocation constraint of phonemes and phonological structure of the word, which are: Obligatory Contour Principle (OCP), Sonority Sequencing Principle (SSP) and Syllable Contact Law (SCL). On basis of these rules and principles the clusters are separated from sequences, and the syllable structure of each language is acquired. Finally the progress of the syllable structure change is studied through representing the data from all three languages, and investigating the process taken for clusters to reach the present time. As the data exhibits, in O.P initial consonant clusters are frequently observed and also, through syllabification, some final syllable clusters will be obtained. In Mi.P also both initial and final clusters fully exist, with growing number of final ones. Initial consonant clusters are completely omitted in Mo.P and only final clusters remain. Deletion and vowel insertion are the two most occurring processes in these processes.

Speaking is a significant skill that many foreign language learners are trying to master. In this study, the effectiveness of two different speaking activities, i.e. oral presentation vs. free discussion, was investigated from quantitative and qualitative points of view. To achieve this purpose, 44 intermediate learners from a language institute in Tehran participated in the study. Half of the participants experienced oral presentation while the other half (22 in two other classes) experienced free discussion for eight sessions. The two activities were exchanged between the two groups after the end of the quantitative phase of the study for eight more sessions. The results of an independent samples t-test performed on the scores ofthe speaking section of a sample Preliminary English Test (PET, 2012 ) after the first phase of the study (the first 8 sessions) indicated that the learners who experienced oral presentation significantly outperformed the learners who experienced free discussion though both activities proved to be significantly useful. Furthermore, the results of the interview with 10 participants from each activity through purposeful sampling, after the second phase of the study (the second 8 sessions) through thematic analysis indicated that both free discussion and oral presentation activities had some merits and demerits. Based on the results it can be advisable to include the two activities as complementary.
