They provide examples of word chunks and collocations, such as 'at eight o'clock' and 'at nine o'clock', and emphasize the significance of paying attention to these patterns in real-world situations. By cultivating curiosity and noticing these patterns in podcasts and TV series, listeners can gradually incorporate them into their own speech, leading to natural and fluent communication.
