The idea of test-tube babies may make you either delighted at the wonders of modern medicine or irritated while considering the moral, or legal, or technological implications of starting tire in a laboratory. But if you’ve ever been pregnant yourself, one thing is certain: You wonder what it’s like to carry a test-tube baby. Are these pregnancies normal? Are the babies normal?
The earliest answers come from Australia, where a group of medical experts at the Queen Victoria Medical Center in Melbourne have taken a look at the continent’s first nine successful invitro pregnancies. The Australians report that the pregnancies themselves seemed to have proceeded according to plan, but at birth some unusual trends did show up seven of the nine babies turned out to be girls. Six of the nine were delivered by Caesarean section. And one baby, a twin, was born with a serious heart defect and a few days later developed life-threatening problems.
What does it all mean? Even the doctors don’t know for sure, because the numbers are so small. The proportion of girls to buys is high, but until there are many more test-tube babies no one will know whether that’s something that just happened to be like that or something special that happens when egg meets sperm in a test tube instead of a fallopian tube. The same thin is true of the single heart defect. It usually shows up in only 15 out of 60 000 births in that part of Australia, but the fact that it occurred in one out of nine test-tube babies does not necessarily mean that they are at special risk. One thing the doctors can explain is the high number of Caesareans. Most of the mothers were older, had long histories of fertility problems and in some cases had had surgery on the fallopian tubes, all of which made them likely candidates for Caesareans anyway.
The Australian researchers report that they are quite encouraged. All the babies are now making normal progress, even the twin with the birth defects.
选项
A、Whether the pregnancies of test-tube babies would be normal.
B、Whether the test-tube babies would be encouraged.
C、Why the proportion of defected babies is so high.
D、Why the number of Caesareans is so high.
答案
A
解析
由题干中的concern定位到原文首段第二、三、四句You wonder what it’s like to carry a test-tube baby. Are these pregnancies normal? Are the babies normal?[精析] 推理判断题[考频:66]。原文首段就指出,人们所担心的问题是怀孕及试管婴儿是否正常。文章就是围绕normal这个关键词陈述现象并分析实验结果的。故A)正确。[避错] B)“试管婴儿是否被鼓励”,文中仅在第一段开始提到人们对试管婴儿的两种态度:delighted and irritated(高兴或被激怒),这不是人们担心的内容:C)“为什么有缺陷的孩子的比例那么高”和D)“为什么剖腹产的数量那么高”,这两项都是后文提到的,澳大利亚的医学专家分析了原因,而且这也超出了人们担心的范围,故这两项也要排除。
