The【C2】______on their research is published in the June edition of the journal Nature. The scientists say: "Information acquired during waking can be reactivated(重新激活)during sleep,【C3】______memory stabilization. " Test volunteers practiced musical tunes before and after a short sleep.【C4】______the nap, the researchers played one of the tunes the volunteers had practiced. The team found that the participants made【C5】______errors when playing the tune that had been played while they slept.
    Study co-author Dr Pau J. Reuber points out the research might not work【C6】______learning a foreign language while you sleep. He said: "The critical【C7】______is that our research shows that memory is strengthened for something you’ve already learned. " He added: "Rather than learning something【C8】______in your sleep, we’re talking about enhancing an existing memory by reactivating information recently acquired. "【C9】______, Dr Reuber did say there were possibilities for language learners; "If you were learning【C10】______to speak in a foreign language during the day, for example, and then tried to reactivate those memories during sleep, perhaps you might enhance your learning," he said.
【C9】
选项 A、However
B、Therefore
C、Moreover
D、Instead
答案A
解析 在本段的第一个句子中罗伯博士指出这一研究也许对睡眠期间学外语不起作用，而本题空格后的句子指出，罗伯博士确实说对于语言学习者来说是有可能性的。很显然，后一句子的意思发生了转折，因此空格中应填入一个表示转折关系的连接词，正确答案为A项However(然而)。干扰项中，Therefore(因此)表示因果关系，Moreover(而且)表示递进关系，Instead(代替，顶替)表示相反的意思。
