The aim of the book is to have the learner engage in smooth interaction with others via the thorough practice of the conversations in the book, and to that end each chapter has "Text Conversation," "Expressions," "Conversation Practice 1" and "Conversation Practice 2" sections, allowing for progressive practice. Particularly in the conversation practice sections, the learner can practice the conscious deployment of words and expressions, so he/she doesn't just memorize the expressions but can connect them to his or her own situation.

Together with "Intermediate 1" and "Advanced," this is a series of three books. Depending on the level of the learner, this book can be used alone, but if used after "Intermediate 1," it will effectively increase the conversational skills of the learner, allowing for the smooth and advantageous promotion of business.
