[解析]
(1)B.细节理解题。根据第三段中的Participants who took a nap were asked about their dreams after sleeping﹣and they were awakened within a minute of sleeping to describe their dreams.(午睡的参与者在睡觉后被问及他们的梦,他们在睡觉后一分钟内被叫醒来描述他们的梦。)可知在小睡片刻后,实验参与者被要求试着回忆与他们梦境有关的一些事情,结合选项,故选B。
(2)D.推理判断题。根据第五段第一句"Four of the 50 people who slept said their dreams were connected to the maze"(50个睡着的人中有4个说他们的梦与迷宫有关) 和第三句"When these four people tried the computer maze again,they were able to find the tree faster than before their naps"(当这四个人再次尝试电脑迷宫时,他们能够比午睡前更快地找到树。)可知梦境与迷宫有关的参与者可以更快找到那棵树,D项正确。故选D。
(3)C.细节理解题。根据第六段第二句"He suspects that the dream was caused by the brain processed associated with learning." (他怀疑这个梦是由与学习相关的大脑处理过程引起的。)可知斯蒂克戈尔德认为梦境是大脑中与学习有关的过程所引发的,故正确答案为B。
(4)C.标题确定题。根据第一段最后一句 "In a recent study,scientists found a connection between nap﹣time dreams and better memory in people who were learning a new skill." (在最近的一项研究中,科学家们发现,在人们学习一项新技能时,午睡时做的梦和更好的记忆力之间存在联系。)可知本文主要是说明梦境可以促进记忆,因此C项Dreaming and Memory适合作为标题,故选C。
