184. Our friendly, aggressive, and sleepy feelings all relate to stage 2 sleep, which accounts _____ most of our total sleep hours. A. down B. to C. from D. for
答
D. account for （数量上、比例上）占……
friendly, aggressive, and sleepy 都是修饰feelings的,relate是谓语；which引导的是一个定语从句,修饰stage 2 sleep.
整个句子的主干是：Our feelings all relate to stage 2 sleep.
