One of the most dangerous drugs for pregnant women to consume is alcohol. Because alcohol is delivered quickly into the blood and passes quickly into the tissues and membranes, the human fetus(胎儿)is particularly vulnerable to its effects. In fact, the negative effects on a fetus are so pronounced that babies born after exposure to alcohol are said to be suffering from fetal alcohol syndrome.
As a pregnant woman drinks alcohol, the alcohol is passed into her bloodstream almost simultaneously. Moreover, because the bloodstream of a fetus is inextricably tied to that of the mother, the alcohol passes directly into the bloodstream of the fetus as well.
And, what is more, the concentration of alcohol in the fetus is exactly the same as in the mother. For the mother, this concentration is not a problem because her liver can remove one ounce of alcohol from her system per hour. However, the fetus’ s liver is not completely developed. The rate at which it is able to eliminate the alcohol from the blood of the fetus is much slower.
Eventually, the alcohol will be returned to the mother’ s system by passing across the placenta(胎盘), but this process is slow. By the time this takes place, major neurological damage may have already occurred. Research has shown that little as one drink of alcohol can produce significant, irreversible damage to fetus.
Babies born after exposure to alcohol generally exhibit facial distortion, inability to concentrate and difficulty in remembering. Simply speaking, it is imperative that pregnant women avoid alcohol. [br] How much time can it be inferred that it takes alcohol to enter a women’ s bloodstream after she takes a drink?
选项
A、About one hour.
B、A few seconds.
C、Several minutes.
D、At least 24 hours.
答案
B
解析
语意推断题。定位句提到孕妇饮酒后,酒精几乎同时进入母体血液中,而母体血液与胎儿是相通的,所以也直接同时进入胎儿血液中,其时间非常短。
