有没有人做陈虎平的《阅读制胜法则》这本书？

many people behave like strong reciprocators.In a ten-round public goods experiment,each subject grouped with three other subjects under conditions of strict anonymity is given "points",divided between a “common account”and the subject's "private account".Each private account will be added by 40%of the total amount of points contributed to the common account.Clearly,full free riding is a dominant strategy,but the experiment shows that many subjects begin by contributing on average about half of their endowment to the public account.However, the level of contributing decays gradually,until in the final rounds most plays behave in a subjects retaliated against free-riding low contributors in the only way available to them-by lowering theri own contributions.This interpretation is confirmed in a 25-round game。这段话有人帮忙翻译下吗？没看懂呀！
