问题     When lab rats sleep, their brains revisit the maze they navigated during the day, according to a new study (1)_____ yesterday, offering some of the strongest evidence (2)_____ that animals do indeed dream. Experiments with sleeping rats found that cells in the animals’ brains fire in a distinctive pattern (3)_____ the pattern that occurs when they are (4)_____ and trying to learn their way around a maze.
    Based on the results, the researchers concluded the rats were dreaming about the maze, (5)_____ reviewing what they had learned while awake to (6)_____ the memories.
    Researchers have long known that animals go (7)_____ the same types of sleep phases that people do, including rapid-eye-movement (REM) sleep, which is when people dream. But (8)_____ the occasional twitching, growling or barking that any dog owner has (9)_____ in his or her sleeping pet, there’s been (10)_____ direct evidence that animals (11)_____. If animals dream, it suggests they might have more (12)_____ mental functions than had been (13)_____.
    "We have as humans felt that this (14)_____ of memory—our ability to recall sequences of experiences—was something that was (15)_____ human", Wilson said. "The fact that we see this in rodents (16)_____ suggest they can evaluate their experience in a significant way. Animals may be (17)_____ about more than we had previously considered".
    The findings also provide new support for a leading theory for (18)_____ humans sleep—to solidify new learning. "People are now really nailing down the fact that the brain during sleep is (19)_____ its activity at least for the time immediately before sleep and almost undoubtedly using that review to (20)_____ or integrate those memories into more usable forms", said an assistant professor of psychiatry at Harvard Medical School.


选项 A、intersecting
B、paralleling
C、resembling
D、differing

答案C

解析 首段首句谈到老鼠睡着时大脑会重访迷宫。也就是说睡着时大脑的状态跟醒时走迷宫的状态很相似。本空白前是睡眠时的pattern,空白后是"the pattern that occurs when they are...and trying to learn their way around a maze",可以判断出空白后应该指醒时走迷宫的pattern。显然两者应该是相似的,故resembling正确。intersecting(相交)、differing(不同)容易排除。paralleling意为"平行"。
