介绍： Rather, we have a certain conception of theAmerican citizen, a character who is incomplete if he cannot competently assess how his livelihood and happiness are affected by things outside of himself.
译文：相反，我们对美国公民有个特定的观念，即如果他不能恰当地评定自己的生计和幸福如何受到外界的影响，那么其公民特征就是不完整的。
点睛：本句的主干为we have a…conception…，acharacter是the American citizen的同位语，其后是由who引导的定语从句。该定语从句是一个复合句，其中包含了一个if引导的条件状语从句，该状语从句中的谓语动词assess后面是一个由how引导的宾语从句。assess意为“评定;估定(财产的)价值”。livelihood意为“生活;生计”。
