As being strongly interested in abstract concepts, their operations and the way people use them in their speech unconsciously, I worked on Image schemas in Saadi poems, one of the most popular and well known Iranian classic poets in my thesis. But, I did not find any subjects related to cognitive linguistics in special issue title. On the other hand, being involved with English as a second language, I have been teaching English for fourteen years. So, having access to learners’ performance at different level of educational and social positions, I can exactly analyze how they learn and improve their four skills: speaking, writing, reading and listening. For example, at the beginning steps of learning, learners transfer their mother tongues’ structures while speaking English. This transferring can be both positive and negative. Getting more familiar with English, they will be aware of using right structures in a suitable way to express their thoughts and to be perceived. The same story is true about using the vocabularies. They learn lots of vocabularies but, they do not know how to use them correctly. So, I can observe the outcome of linguistic studies through the data, the learners’ productions. As the matter of fact, learning the second language is highly complicated and valid in linguistic studies, because it is somehow similar to acquiring the first language.
