问题 The author thinks sleep is a funny thing as it is necessary for human life.
According to Joel Achenbach, while dreaming, our brains experience ______.
选项
答案random electrical activity
解析 第6个小标题Dreams部分的第2段第1句：The brain creates dreams through random electrical activity．空白处需要名词性成分。原文中用through，题目用experience，其实表示的都是方式，故答案为through后面的名词短语random electrical activity。
