It’s late in the evening: time to close the book and turn off the computer. You’re done for the day. What you may not realize, however, is that the learning process actually continues—in your dreams.

    It might sound like science fiction, but researchers are increasingly focusing on the relationship between the knowledge and skills our brains absorb during the day and the fragmented, often bizarre imaginings they generate at night. Scientists have found that dreaming about a task we’ve learned is associated with improved performance in that activity (suggesting that there’s some truth to the popular notion that we’re “getting” a foreign language once we begin dreaming in it). What’s more, researchers are coming to recognize that dreaming is an essential part of understanding, organizing and retaining what we learn.

    While we sleep, research indicates, the brain replays the patterns of activity it experienced during waking hours, allowing us to enter what one psychologist calls a neural (神经的) virtual reality. A vivid example of such replay can be seen in a video researchers made recently about sleep disorders. They taught a series of dance moves to a group of patients with conditions like sleepwalking, in which the sleeper engages in the kind of physical movement that does not normally occur during sleep. They then videotaped the subjects as they slept. Lying in bed, eyes closed, one female patient on the tape performs the dance moves she learned earlier.

    This shows that while our bodies are at rest, our brains are drawing what’s important from the information and events we’ve recently encountered, then integrating that data into the vast store of what we already know. In a 2010 study, researchers at Harvard Medical School reported that college students who dreamed about a computer maze (迷宫) task they had learned showed a 10-fold improvement in their ability to find their way through the maze compared with participants who did not dream about the task.

    Robert Stickgold, one of the Harvard researchers, suggests that studying right before bedtime or taking a nap following a study session in the afternoon might increase the odds of dreaming about the material. Think about that as your head hits the pillow tonight.

解析：A。本题为推断题，需要结合全文才能得出答案。文章第一、二段提到，研究表明，梦到所学内容有助于提升学习效果，在第三、四段中通过介绍两项相关研究来印证这一说法，并在最后一段给出了专家的相关建议，即我们可以通过在入睡前学习或在学习后小睡来增加梦到所学内容的几率。A项与文章主旨内容相符，即作者基于科学研究来建议人们借助做梦来促进学习，故A项为正确答案。

错项排除：原文第二段第二句提到，人们认为，在梦里讲外语就说明做梦者已经对这门语言“开窍”了，但这只是为了从侧面印证“梦到所学内容对提升学习效果有帮助”这一观点，并不等同于只要做梦就可以提升语言能力，原文未提及这两者间存在因果关系，故B项排除。原文第三段中讲到对梦游症患者的研究，即这些患者在白天学习了舞蹈动作之后，有一名患者在梦游时会做同样的动作，但并没有说所有梦游者都会表演舞蹈动作，C项中的All过于绝对，故排除。D项利用原文第四段结尾的find their way through the maze和第五段的taking a nap设置干扰，但这两部分信息之间没有关联，D项属于细节拼凑，故排除。
