The document discusses 5 different communicative styles: casual, consultative, formal, frozen, and intimate. Casual style is informal language used between friends and includes slang. Consultative style is semi-formal and used in two-way discussions. Formal style is straightforward with planned sentences and avoids slang. Frozen style rarely changes and is the most formal, using long static sentences. Intimate style is private conversations between close relationships with no social boundaries. The document provides examples of situations that would use each style, such as tweets for casual, doctor-patient for consultative, speeches for formal, and national anthems for frozen. It also includes a short quiz matching examples to the different styles.
