2015考研英语阅读婴儿贫血

　　来自瑞典哈尔姆斯塔德市哈兰医院的产科医生Ola Andersson刚刚在不列颠医学杂志上发表的一项研究表明，简单改变婴儿分娩的流程，也许就能显著降低贫血症的发生。这个改变是，不要像惯常操作那样，在胎儿出生后马上剪断连接胎儿与胎盘的脐带，而是等一等，让更多胎盘中的物质流向胎儿。

　　The argument in favour of rapid clamping is that too much blood may flow from thedetached placenta to the newly born child, and that this can cause problems of its own. Butthat is unproven, and would be a strike against evolution because, in nature, the umbilicusof a mammal usually does remain attached to the infant for some time after birth. Only themodern technology of clamps and sharp scissors permits the slithery tube to be dealt with atspeed.

　　坚持快速钳住脐带的观点认为，让太多的血液从胎盘流向新生儿会带来其自身的问题，但这种观点其实从未被证实，而且显然与进化论相抵触，因为在自然界中，哺乳动物的胎儿通常在出生后一段时间内仍然通过脐带与母体相连，只有钳子和剪子这种现代工具，才能迅速地处理光滑的脐带。

　　To test her idea that extended post partum connection to the placenta is good for a child shealth, Dr Andersson and her colleagues recruited 334 pregnant, non-smoking women whosefetuses appeared to be healthy. When these women came to term, their midwives followedone of two sets of instructions, chosen at random and given to them just before each birth.In 166 cases the newborns had their umbilical cords clamped within ten seconds of delivery.The other 168 had them clamped after at least three minutes had passed.
