参考答案
参考解析
解析：
句意：一旦灯塔建立起来，以航海为目的的任何国籍的船只都可以有效地加以利用。整个句子采用了双重否定形式来表示肯定的含义。excluded被排除在外的，符合句意。isolated被孤立，被隔离与from搭配，表示和其他事物隔离，不与之来往等意思，dismissed被某个组织或群体开除或解职，某组织、协会、机构被解散。distracted也可以和from搭配，表示“被转移，被分散”，但一般表示兴趣、注意力的分散。

Public goods are those products from whose enjoyment nobody can be effectively excluded. Everybody is free to enjoy the benefits of these commodities, and one person’s utilization(利用)does not reduce the possibilities of anybody else’s enjoying the same good.Examples of public goods are not as rare as one might expect. A flood control dam is a public good. Once the dam is built, all persons living in the area will benefit--regardless of their own contribution to the construction cost of the dam. The same holds true for highway signs or aids to navigation. Once a lighthouse is built, no ship of any nationality can be effectively excluded from the utilization of the lighthouse for navigational purposes. National defense is another example. Even a person who voted against military expenditures or did not pay any taxes will benefit from the protection afforded.It is no easy task to determine the social costs and social benefits associated with a public good. There is no practicable way of charging drivers for looking at highway signs, sailors for watching a lighthouse, and citizens for the security provided to them through national defense.Because the market does not provide the necessary signals, economic analysis has to be substituted(代替) for the impersonal judgement of the marketplace.31.
