Why is listening important in learning English?
Listening is important mainly for two reasons. First, we cannot develop speaking skills unless we also develop listening skills. To have a successful conversation, students must understand what is said to them. Later the ability to understand spoken English may become very important. Second, listening to spoken English is an important way of acquiring the language, while in our situation the students do not hear English spoken around them, so it is important for us to give our students as much opportunity as possible to listen to spoken English.
