There are only 24 hours in a day，and usually about a third of that is spent sleeping. So is it possible to make use of this time and learn a new skill or even a language? In other words，is sleep learning possible?
Many studies have found that a basic form of learning，called conditioning，can happen during sleep. In a 2012 study published in the magazine Nature Neuroscience，for example，Israeli researchers found that people can learn to connect sounds with smells during sleep. The scientists played a tone(声音) to sleeping study participants(参与者) while putting some rotten(腐烂的) fish beside their beds. Once awake，when hearing the tone，the people held their breath in anticipation(预判) of a bad smell.
"This was a clear finding showing participants formed new memories during sleep，" said Andrillon，a scientist in this field.
Although the new memory was implicit (暗示性的)，it could influence how people behave，researchers found in a 2014 study published in the Journal of Neuroscience. In that research after spending a night in a room full of cigarette(香烟) smell mixed with rotten eggs or fish，smokers use fewer cigarettes.
Andrillon and his team members have found that learning in sleep can also go beyond simple conditioning. In their 2017 study published in Nature Communications，participants were able to pick out sound features that they had heard during sleep.
Learning abilities in sleep may spread to learning of words. In a study published in Current Biology，researchers played pairs of made-up words and their supposed meanings，like "guga" meaning elephant，to sleep participants. After this，when awake，the participants did better in picking the right translation of made-up words in a multi-choice test.
So far，research suggests it may be possible to learn about the tone and pronunciation of a language or even the meaning of words while sleeping，although it is to a weaker level than what we do during the day without noticing.
( )1. What is the main purpose of the text?
A. To show that sleep learning is possible.
B. To study how to make use of sleep learning.
C. To report some famous research findings.
D. To prove sleep learning is implicit and weak.

答案： A
解析：文章开篇提出“is sleep learning possible?”，随后通过多项研究说明睡眠中可发生学习，如声音与气味的联系、语言学习等，核心目的是证明睡眠学习是可能的，故选A。

( )2. What does the underlined phrase "new memories" in Paragraph 3 refer to?
A. Connection between participants and scientists.
B. Connection between sounds and smells.
C. The tone's influence on the rotten fish.
D. The rotten eggs' influence on cigarettes.

答案： B
解析：第三段提及2012年研究中，参与者在睡眠中学习将声音与气味联系，醒来后听到声音会预判臭味，因此“new memories”指“声音与气味的联系”，故选B。

( )3. What is the main idea of the last two paragraphs?
A. Sleep can do good to learning.
B. Language learning can happen in sleep.
C. People learn in sleep in a different language.
D. Sleep learning is better than daytime learning.

答案： B
解析：最后两段提到睡眠中能识别声音特征、学习单词含义及语言发音，核心是“语言学习可在睡眠中发生”，故选B。
