    Alcohol may taste sweeter if you were exposed to it before birth, suggests a study in rats. The findings may shed new light on why human studies have previously【C1】________ fetal (胎儿的) alcohol exposure to increased alcohol【C2】________ later in life, and to a lower age at which a person first starts drinking alcohol.
    Alcohol’s taste is a(n)【C3】________ of sweet and bitter components. To test whether prenatal (产前的) alcohol exposure could【C4】________ the perception of these components, Steven Youngentob at the State University of New York in Syracuse and John Glendinning at Columbia University in New York【C5】________ how eagerly rats consumed alcohol, sweet water or bitter water.
    They found that young rats whose mothers had consumed alcohol during pregnancy preferred alcohol and consumed more of the bitter water than the【C6】________ of mothers that didn’t consume alcohol. Rats that had been exposed to alcohol before birth also seemed to be more【C7】________ to the smell of alcohol.
    Prenatal exposure seems to reduce the【C8】________ bitterness of alcohol, making it seem sweeter, says Youngentob. Both of these differences seemed to【C9】________ once the rats reached adulthood—but only if they hadn’t tasted alcohol during their youth. If prenatally exposed rats did consume alcohol in their youth, these preferences seemed to become【C10】________ for life.
    "The take-home message is to keep kids away from alcohol for as long as possible—particularly if they have had prenatal exposure," says Youngentob. [br] 【C6】

选项

答案 O

解析 此处为比较结构,对比的对象应是对等的事物,故“young rats whose…”和“________of mothers“对等,词库中的offspring“后代”代入后符合句意。
