　　But economists say families about to go into debt to fund four years of partying, as well as studying, can console themselves with the knowledge that college is an investment that, unlike many bank stocks, should yield huge dividends. (09.6 Passage 2)

　　主干：...economists say (families... can console themselves with...)

　　1. say后面的内容都是say的宾语。该宾语从句的主语是families，其后又一个不定式短语to go...修饰；不定式to fund...作前一个不定式to go into debt的目的状语；as well as相当于一个并列连词，连接partying和studying。
2. knowledge后的that从句作其同位语，说明“该知识”的具体内容；an investment后的that引导的是定语从句，从句的主语和谓语被插入成分unlike...隔开了。

　　译文：不过经济学家说大学是一项投资，而且和许多银行股票不同的是，这项投资可以带来巨大的红利，打算举债来提供4您狂欢和学习资金的家庭在知道这一点之后可以有所安慰了。
