Students should be jealous.Not only do babies get to doze their days away,but they've also mastered the fine art of learning in their sleep.
By the time babies are a year old they can recognize a lot of sounds and even simple words. Marie Cheour at the University of Turku in Finland suspected that they might progress this fast because they learn language while they sleep as well as when they are awake.
To test the theory,Cheour and her colleagues studied 45 newborn babies in the first days of their lives. They exposed all the infants to an hour of Finnish vowel sounds一one that sounds like "oo",another like"ee"and a third boundary vowel peculiar to Finnish and similar languages that sounds like something in between. EEG recordings of the infants brains before and after the session showed that the newborns could not distinguish the sounds.
Fifteen of the babies then went back with their mothers,while the rest were split into two sleepstudy groups.One group was exposed throughout their night-time sleeping hours to the same three vowels,while the others listened to the other,easier-to-distinguish vowel sounds.
When tested in the morning,and again in the evening,the babies who'd heard the tricky boundary vowels all night showed brainwave activity indicating that they could now recognize this sound.They could identify the sound even when its pitch was changed,while none of the other babies could pick up the boundary vowel at all.
Cheour doesn't know how babies accomplish this night-time learning,but she suspects that the special ability might indicate that unlike adults,babies don't"turn off" their cerebral cortex while they sleep.The skill probably fades in the course of the first years of life,she adds,so forget the idea that you can pick up the tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not help grown-ups,Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders.
选项 The study shows that the infant's cerebral cortex is working while he is asleep.
A:Right       
B:Wrong       
C:Not mentioned
答案A
解析相关信息在第一段：Students should be jealous.Not only do babies get to doze their days away, but they've also mastered the fine art of learning in their sleep．学生们应该感到嫉妒。婴儿们不仅整天睡觉，而且他们掌握了在睡眠中学习的技艺。Not only… but also＝not only…but…，意思是“不但……而且……”。
第二段第一句提到：By the time babies are a year old they can recognize a lot of sounds and even simple words．但问题句中提到的是vowels（元音），之后也没有相关信息。因此判断该问题句为“没提到”。
文中没有提到芬兰元音是否容易区分，因此该题的答案为C。
第三段第二句提到：They exposed all the infants to an hour of Finnish vowel sounds一one that sounds like"oo",another like"ee"and a third boundary vowel peculiar to Finnish…因此该句是正确的。
第六段第一句：Cheour doesn' t know how babies accomplish this night-time learning,but she suspects that the special ability might indicate that unlike adults,babies don't "turn off" their cerebral cortex while they sleep．该句在语意上和题干一致，因此判断问题句的说法正确。
第六段第二句：The skill probably fades in the course of the first year of life, she adds,so forget the idea that you call pick up tricky French vowels as an adult just by slipping a language tape under your pillow．该句在内容上与问题句（If an adult wants to learn a language faster, he can put a language tape under his pillow）内容相反，因此判断该问题句的说法错误。
借助常识，判断该题的说法错误，文章中通常不会提出没有用的东西来浪费读者的时间。在文章最后部分，也可以找到答案相关句：But while it may not help grown-ups, Cheour is hoping to use the sleeping hours to give remedial help to babies who are genetically at risk of language disorders.it才旨代前句中的the skill，即the night-time-learning( Cheour的发现内容）。该句内容与问题句内容不一致，因此判断该题的说法错误。
