There are many different kinds of sites. We often speak of construction sites, a site where something is being built – such as buildings, roads, bridges, airports, and so on. But a site can also be a completed structure, like a factory or even sometimes an office. In a site visit, visitors come on site to have a look around. Someone in your company will usually play host and give them a tour. this is often part of the sales process: Sometimes it's the visitors who are selling something to the host, and sometimes it's other way around.
世界上有各种各样不同的工地。我们经常说“工地建设”，一个正在建设的工地，包括房屋，路面，桥梁，机场等等。但是场所也可能是一个完整的建筑物，像工厂或者有时候像一个办公室。在一个工地参观，参观者通常是四处看看。在你的公司里有人就会作为向导，带领他们参观。这通常就是一个销售过程，有时候参观者会向东道主卖东西，有的时候则相反。
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.
在本章中我们学习的语言对于以主人身份接待来客者是很有用处的。不管你是否给了记者关于工厂的描述，或者是介绍潜在的客户来我们的办公地点，或者是给政府官员介绍工程建设，我们都需要带领他们参观并把注意力引向他们感兴趣的地方。
