问题     A device to "sleep on it" could be well founded, scientists say. After a good night’s sleep, a problem that seemed insurmountable(不能克服的)the night before can often appear more【S1】______, although the evidence until now has been anecdotal(轶事的，趣闻的). But【S2】______at the University of Luebek in Germany  have designed an experiment that shows a good night’s sleep can【S3】______insight and problem-solving. Dr. Jan Born, a neuroscientist at the university, and his team taught volunteers two simple rules to help them【S4】______a string of numbers into a new order. There was also a third,【S5】______rule, which could help them increase their speed in solving the problem. The researchers divided the volunteers into two groups, half were allowed to sleep after the training while the【S6】______were forced to stay awake. They noticed that the group that had slept after the training were twice as【S7】______to figure out the third rule as the other group. "You have a memory representation in your brain of the problem you want to solve, and then you sleep. Sleep can act on the problem." Born said in a telephone interview. But he also admitted that how【S8】______of memories occurs or what governs it is still unknown. Other scientists say the【S9】______evidence supports the anecdotal suggestions that sleep can【S10】______creative thinking. Although the role of sleep in human creativity will still be a mystery, the research gives people good reason to fully respect their periods of sleep.

选项
答案B)
解析 副词辨义题。该句即使不填入任何词，句意也可以很好地表达，说明此处只是需要一个做修饰语的副词。上文说虽然实验结果可以证实睡眠确实改善我们的洞察力和解决问题的能力，但究意这种效果是怎么达到的还是未知的。B still“仍然，依然”符合题意。
