One leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better.
【词汇突破】authority 权威harness 使……停止的意思;和stop 可以互换但是更加正式的表达;还有一个单词是curb，这个单词表示控制的意思相当于control，原意是缰绳的意思，这个单词为考研常考词。conscious 有意识的 intensely powerful mental event在原文中就等于dreams;
【主干识别】one leading authority says that+宾语从句;
【其他成分】宾语从句的主干是these intensely powerful mental events can be not only harnessed but actually brought under conscious control; 并列连词not only …but also…连接两个并列的动词harnessed 和 brought;to help us sleep and feel better 为目的状语
【译文赏析】而一名知名人士认为，这些极其强烈的大脑活动不仅可以被抑制，实际上还可以受到意识的控制，进而帮助我们睡眠，使我们感觉好一些。
