共享题干题阅读下面材料，回答下列的问题： Easy Learning Students should be jealous． Not only do babies get to doze their days away, but they've alsomastered 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 mightprogress this fast because they learn language while they sleep as well as whenthey are awake． To test the theory, Cheour and her colleagues studied 45 newborn babies in the firstfew days of their lives． They exposed all the infants to an hour of Finnishvowel sounds -- one that sounds like "oo", another like"ee" and a third boundary vowel peculiar to Finnish and similar languagesthat sounds like something in between． EEG recordings of the infants brainsbefore and after the session showed that the newborns could not distinguish thesounds． Fifteen of the babies then went back with their mothers, while the rest were split intotwo sleep-study groups．One group was exposed throughout their night-timesleeping hours to the same three vowels, while the others listened to other,easier-to-distinguish vowel sounds． When tested in the morning, and again in the evening, the babies who'd heard thetricky boundary vowel all night showed brainwave activity indicating that theycould now recognize this new sound They could identify the sound even when itspitch was changed, while none of the other babies could pick up the boundaryvowel at all． Cheour doesn't know how babies accomplish this night-time learning, but she suspectsthat the special ability might indicate that unlike adults, babies don't"turn off" their cerebral cortex while they sleep． The skill probablyfades in the course of the first year of life, she adds -- so forget the ideathat you can pick up tricky French vowels as an adult just by slipping alanguage tape under your pillow． But while it may not help grown-ups, Cheour ishoping to use the sleeping hours to give remedial help to babies who aregenetically at risk of language disorders．1.[不定向选择题]Aninfant can recognize a lot of vowels by the time he or she is a year oldA.Right B.Wrong C.NotmentionedABC确定 2.[不定向选择题]Thestudy shows that the infant's cerebral cortex is working while he is asleep．A.Right B.Wrong C.NotmentionedABC确定

1.参考答案：C
参考解析：题干：婴儿在一岁左右的时候，能辨识很多元音。?A、正确B、错误C、未提及?第二段第一句说：“By the time babies ale a year old they can recognize a 10t of soundsand even simple words．”即“婴儿到了一岁时，他们可以识 别许多音，甚至一些简单的词。”从“许多音”是推导不出“许多元音” 的。sound和vowel之间不是等同关系，因此选择未提及。?
2.参考答案：A
参考解析：题干：此研究表明，婴儿睡觉时大脑皮层仍在工作。?A、正确B、错误C、未提及?答案可以从下面这个句子中找到：“一ulllike adults，babies don’t‘turn off’theircerebral cortex while they sleep．”即“……跟大人不一样，婴儿 睡觉时没有把大脑皮层‘关掉”’。故选A。?3.[不定向选择题]Finnish vowels are easy to distinguish．A.Right B.Wrong C.NotmentionedABC确定
