Listening materials are a very rich source of language input. In a text-based lesson, listenings will always generate language to be analysed and, above  all, allow learners to capitalise on lexis. As Brazilian Portuguese is a syllable-timed language - English is stress-timed - the script is an invaluable tool so as to draw learners' attention to pronunciation features, say, at both segmental and supra-segmental levels. Hence, shadow reading is one strategy I often use to get learners to pick up rhythm and intonation. That said, once learners become aware that working on those differences will lead them to similaries, they feel more confident and will transfer such features to their daily speech.
