标志： That each large firm will act /with consideration of its own needs/ and thus avoid selling its products for more than its competitors' charge is commonly recognized /by advocates of free-market economic theories/.

译文： 每一个大公司 都将 /考虑到其自身的需求/，而且这样就会 避免比 其竞争对手把其商品卖得更贵 ，这一点 通常被 /自由市场的经济理论的支持者/所认识到 。

解释： 本句一开始就是一个that引导的主语从句，而且因为它是由表示并列和递进的and thus 连接的两个句子组成的，因此出奇地长，造成的结果就是不熟悉难句结构的读者读到后面的is commonly recognized by的时候，已经搞不清楚是什么被认识到了。
