Different situations require different types of listening. We may listen to obtain information, improve a relationship, gain appreciation for something, make discriminations, or engage in a critical evaluation.While certain skills are basic and necessary for all types of listening (receiving, attending, and understanding), each type requires some special skills. Chapter 2 ,3 discusses those special skills and presents guidelines to improve listening behavior in all situations. But before we can fully appreciate the skills and apply the guidelines, we must understand the different types of listening.Teaching listening skills is one of the most difficult tasks for any ESL or EFL teacher. This is because successful listening skills are acquired over time and with lots of practice. It's frustrating for students because there are no rules as in grammar teaching. Speaking and writing also have very specific exercises that can lead to improved skills. This is not to say that there are not ways of improving listening skills, however they are difficult to quantify.
