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.
今天这节课中要学到的语言对任何需要招待客人的拜访者都有用。无论我们是给游客介绍工厂，还是介绍潜在的客户介绍我们的工作地点，或是给政府官员介绍建筑工作，我们都需要带领别人参观，并指出有意思的地点。
