In recent years a great number of books have appeared in various fields of ESP، and the number is increasing every year. These books are specially prepared and adapted for foreign students possessing varying degrees of language skills. Experts believe that the production of ESP books is a vital task that requires several stages and procedures. To produce these materials، special attention should be paid to the age of the learners their English background، their level of knowledge in specialist field and the teaching method. The best should be done to provide materials which enable the learners to increase their English proficiency، learn the required skills for communication، and achieve their terminal behavior. Since the majority of university graduates in Iran are not equipped with sufficient knowledge of English to read and understand the original specialized textbooks، this paper aimed to test the appropriateness of materials used in ESP classes، based on a study conducted at Chabahar Maritime University. The finding of this research rejected the null hypothesis، because the observed t. was 2.83 and the value of critical t.’ with the 49 degrees of freedom at the .05 level was 2، and this signifies that the novel content based texts motivated the students and improved their English proficiency.

This paper aims at investigating the acquisition of Italian complex predicates by native speakers of Persian. Complex predication is not as pervasive a phenomenon in Italian as it is in Persian. Yet Italian native speakers use complex predicates productively; spontaneous data show that Persian learners of Italian seem to be perfectly aware of Italian complex predicates and use this familiar feature as a bridge between their native language (NL) and the target language (TL). Elicitation of complex predicates in guided context seems to indicate that the Persian group learners’ group is strikingly uniform to the Native Speakers’ group and quite homogeneous with the control group of learners with NL other than Persian. This research shows that the use of complex predicates in Italian Interlanguage (IL) cannot be considered a simple effect of transfer، but could be also analyzed as a more general IL strategy.

The extensive research done on the interrelationship between different social factors such as social class، gender and age and different linguistic variables has shown that these factors have important effects on the way language is used. Among these factors a special importance can be placed on age due to the role it plays in revealing different patterns of language use، such as the age-grading pattern، the normal pattern of age differentiation and the important patterns of language change which can inform us about the emergence of a linguistic form or the death of some old form. This paper is intended to examine the interrelationship between age and the usage of Shirazi vocabulary or lexical items. Sixty respondents belonging to 6 age groups of Shirazi speakers answered a 60-item questionnaire. Each item included one Shirazi word with its definition and sometimes a short example to clarify its meaning. The respondents had to choose between two choices: either they used the item or they did not. The analysis of the results showed that age was an influencing factor on the speech of the speakers as the older people had a large collection of active Shirazi words (they actively used all the words) while the younger generation had two collections of more active and less active Shirazi words and as the age of the subjects increased their mean scores which represented their usage of Shirazi vocabulary items also increased. These words were also used less among the more educated Shirazi speakers.
