参考答案：D

参考解析：

含义题。文中第二段的第二句话对第一句话进行了解释。此题的难点是第二句话为长句。其中It指代前文的safety net，that makes us happy是work的一个定语从句，that is consistent with our desires while still meeting our monetary needs是与前面的that从句并列的work的又一个定语从句。这两句话的意思是:为求稳当，我们需要很大的牺牲：牺牲了为快乐而工作的机会，牺牲了可以满足兴趣，又能赚钱的工作机会。由此可见作者的意思是稳定使人们牺牲了兴趣和赚钱这两者的平衡，其中sacrifice就是trade-of的近义词。D项意思与原文一致。A项：是对这句话概念的错误理解，安全的获得是通过牺牲而来的，而不是靠既满足我们的愿望又满足我们金钱的需要。BC两项中have to太过绝对，排除。故本题正确答案选D。
