The language we’re going to study in this episode will be useful for anyone who needs to host visitors. No matter whether we are giving journalists a demonstration of a factory, or introducing potential customers to our work site, or giving government officials a tour of a construction project, we need to show people around and point out areas of interest.
今天這節課中要學到的語言對任何需要招待客人的拜訪者都有用。無論我們是給游客介紹工廠，還是介紹潛在的客戶介紹我們的工作地點，或是給政府官員介紹建筑工作，我們都需要帶領別人參觀，并指出有意思的地點。
