Question

Even while in a deep sleep, people can still learn brand new information. Sleepers soak in new associations between smells and sounds, knowledge that lingers(逗留）into the next waking day, researchers report online August 26 in Nature Neuroscience.
The new study is the first to show that entirely new information can get into the sleeping mind, says Anat Arzi of the Weizmann Institute of Science in Israel. "The brain is not passive while you sleep. It's quite active. You can do quite a lot of things while you are asleep."
But the results don't mean that Spanish vocabulary tapes now have a place on the nightstand. L, Researchers have tried but largely failed to find evidence that complicated information, such as new pairs of words, can make its way into the brain during sleep.
Instead of trying to teach people something complicated like a new language, Arzi and her colleagues relied on the sense of smell and hearing. As anyone who has walked by a dumpster（垃圾車）in July knows, smells can cause a nose-jerk reaction. Catching a bad smell automatically makes people inhale(吸氣)less, reducing the size of the inhale. But scent of fresh bread causes a long, deep inhale.、rzi and her team took advantage of this reaction for their experiment.
As people slept in the laboratory, the researchers delivered pleasant scent, such as shampoo. As this nice smell got into the sleepers' noses, the researchers played a particular music. Later, a disgusting smell, such as rotten fish or meat, was paired with a different music. Neither the smell nor the sound woke people up. After just four exposures to the smell-music pair during a single night, the sleepers started to automatically respond to the tones without the accompanying smells, taking in bigger breaths when the shampoo-associated tone played and smaller breaths when played the sound linked to the rotten fish smell.
This new learned association lingered into the next waking day, too. Even though the sleepers had no idea they had been exposed to smells or sounds, their behavior proved that their brain had actually learned something during sleep. As before, the shampoo sound stimulated a long, deep inhale, while the rotten fish tone caused more shallow breaths.

Answer 1

小題1:B
小題2:A
小題3:D
小題4:B

試題分析：這篇文章介紹一項研究報告：人們在睡眠的狀態(tài)下不是被動的馬爾斯積極的，可以獲取信息也能第氣味做出反應。
小題1:推理題：從文章第四段的句子: Catching a bad smell automatically makes people inhale(吸氣)less, reducing the size of the inhale ，But scent of fresh bread causes a long, deep inhale.可以推斷出當聞到好聞的氣味，人們會增加吸氣的量，選B
小題2:段落大意題：從第三段的句子：Researchers have tried but largely failed to find evidence that complicated information, such as new pairs of words, can make its way into the brain during sleep.可知這段講的是在睡眠的時候，人們是不能獲得復雜的知識的，選A
小題3:細節(jié)題：從文章第四段的句子：Aizi and her team took advantage of this reaction for their experiment.
可知Arzi 和他的團隊是通過做實驗來做研究的，選D
小題4:文章出處題：通過文章的第一段的內(nèi)容：可知這篇文章介紹人們在睡眠的狀態(tài)下不是被動的馬爾斯積極的，可以獲取信息也能第氣味做出反應，所以是出自報紙的科技版面，選B
