　　A century ago, Freud formulated his revolutionarytheory that dreams were the disguised shadows ofour unconscious desires and fears, by the late1970s, neurologists had switched to thinking of themas just "mental noise"-the random byproducts ofthe neural repair work that goes on during sleep.

　　译文：一个世纪前，弗洛伊德阐述了他革命性的理论，即梦是对人们潜意识中的欲望和恐惧的一种掩饰：到了20世纪70年代末期，神经病学家们转而认为梦是“精神噪音”——睡眼时进行的神经修复中偶然产生的副产品。

　　点睛：本句是个并列句，由分号隔开。第一个分号的主干为Freud formulated…theory...，其后是同位语从句that dreams were the disguised shadows of our unconscious desires and fears。第二个分句的主干为neurologists had switched to thinking of them as just“mental noise”…，破折号后面的部分是mental noise的同位语，对其进行补充说明，其中work后面是定语从句that goes on during sleep。
