问题     U. S. researchers suggest sleeping can help us remember things we have just learnt. A team from Northwestern University【C1】______that a 90-minute nap(小睡)can help people learn a new skill. 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.
【C3】
选项 A、disturbing
B、lowering
C、updating
D、promoting
答案D
解析 本题要求填入一个现在分词，与空格后的memory stabilization(记忆的稳固)构成逻辑上的动宾关系。本句相关部分的意思是：清醒时刻所获得的信息能够在睡眠期间被重新激活，——记忆的稳固。整个句子其实就是对短文开头指出的“睡眠帮助我们记忆所学的东西"的具体说明，因此disturbing(干扰)和lowering(降低)与上文矛盾，可首先排除。updating意为“升级”，从语意上看，不能与之后的宾语搭配。D项promoting意为“促进”，符合语意的要求，是正确答案。
