[originaltext] There are many occasions on which you can be expected to talk

There are many occasions on which you can be expected to talk about your firm. This may include actually showing someone physically around the place of work or premises. But it may more generally involve referring to the way in which the company is organized and run.
    Firms are a very important part of the economy. They are responsible for producing goods and services. Businesses come in every shape and size. While the vast majority of the world’s businesses are small, large firms often dominate the economy in some countries. Indeed, the income of the world’s largest fifty industrial companies added together represents more than haft the total output of the United States.
    Large businesses differ very much from small ones in a wide variety of ways. In many countries there are both private firms and nationalized firms belonging to the government. A small private firm may have just one owner but a very large firm has thousands of shareholders.
    In very large firms the owners have very little to do with the day-to-day running of the firm. This is left to the management. Very large companies may be organized into several large departments, or sometimes even divisions. The organizational structure of some companies is very hierarchical with the board of directors at the top and the various departmental heads reporting to them. Often the only time shareholders can influence the board is at yearly shareholders’ meetings.
    Some firms may only produce one product or service. Others may produce many different products: in fact they may seem to be like a collection of businesses inside one company. The bigger a business becomes the further it may expand geographically. Many large firms have manufacturing plants and trading locations in several different countries spread around the world.
