问题    Does an unborn baby know his mother’s voice? Psychology professor Anthony DeCasper advised an ingenious experiment to find out. He placed padded earphones over a newborn’s ears and gave him a bottle nipple attached to a closed rubber tube. Changes in pressure in the tube switched channels on a tape recorder. If the baby paused extra long between bursts of sucking, he heard on channel; if he paused shorter than average, he heard the other. The baby now had the ability, in effect, to change channels.
   DeCasper found that newborns choose the recording of their mother’s voice over that of another woman’s. The baby, however, has no innate interest in his father’s voice, which is heard in the womb only from time to time, while the mother’s voice is ever present. Within two weeks after birth, however, the baby can recognize Dad’s voice too. A newborn is even attuned to the cadence and rhythm of his native language. In a French study using a setup similar to DeCasper’s, French babies given the choice between French and Russian words responded more to the sound of French.
   Brian Satt, a research specialist in clinical psychology, has parents sing a lullaby-like "womb song" to their babies. The unborn baby often develops a specific, consistent movement pattern when its song is sung. According to Satt, most parents can calm a fussy newborn with the song most of the time, which is a prize worth more than rubies to a new parent.
   He is roused by a heavy jolt. His mother has tripped and fallen heavily on one hip. He is much too well cushioned to experience any injury, but her pain and the fear that she may have hurt him floods both their bodies with adrenaline and other stress-related hormones. He cries and kicks vigorously, a cry never heard because there is no air to make sound. As she recovers the stress hormones ebb away, and he calms down too. [br] Which of the following is NOT mentioned about the unborn baby in the passage.’?
选项 A、An unborn baby can occasionally hear his father’s voice.
B、DeCasper’s approach proved absolutely effective in a French experiment.
C、An unborn baby is able to identify the tone and rhythm of his native language.
D、Parents are able to soothe a fussy newly-born baby.
答案 C
解析 文章第二段提到“The baby．．．voice is ever present”，即婴儿由于在子宫里只是时不时地听到父亲的声音，所以对父亲的声音并没有天生的兴趣，故选项A正确；第二段结尾处提到法国的研究"using a setup similar to DeCasper’s”，即用的是与DeCasper类似的装置，且实验成功，故选项B正确；第三段提到父母“can calm a fussy newborn with the song most of the time”，故选项D正确。而文中第二段只是说新生的婴儿熟悉“the cadence and rhythm of his native language”，并不是未出生的，故答案为C项。
