Concept:The main aim of teaching pronunciation is to ensure that a learner's speech is clear and easily understood, not necessarily to mimic a native speaker perfectly.Explanation:Pronunciation instruction prioritises intelligibility—the ability to be understood by a wide range of listeners. While native-like accuracy can be a long-term aspiration for some, the immediate and realistic goal is to help students produce sounds, stress, and intonation that do not create confusion. Option A (sounding exactly like native speakers) is an unrealistic and unnecessary target for most learners. Option B (repeating words many times) is a classroom activity, not the underlying goal. Option D repeats the same mistaken idea as A. Option C correctly identifies the true purpose: to help students have intelligible pronunciation, which supports effective communication.Answer:C. To help students have intelligible pronunciation.
