A board of directors controls corporate policies. The directors appoint top company officers. The directors might or might not hold shares in the corporation. Corporations can have a few major shareholders, or ownerships can be spread among the general public.董事会控制公司的政策。董事们任命公司的高层。但董事不一定就是该公司股东。公司可以拥有几个主要的股东。所有权也可能为公众广泛持有。___________________________________________________.
