怀孕

不明确的答案

对同一个问题的不同的科学研究有时可能使得外行无所适从，当他们设法了解一个人的生命究竟从哪一个时刻开始的时候，却得到了多个答案。 可是，也许我们还记得现代科学对有关死亡的时刻也有莫衷一是的传统假定。随着越来越多的科学知识积累，生命的肇始和终结已经更加难以定义了。现在要查明这两者的特殊时刻确实是非常困难的。在我们真正能够回答这些难题之前，似乎仍然需要了解更多（和发展更精确的术语学）。

Conception

No definite answer

These different scientific approaches to the same problem may sometimes confuse the layperson who tries to learn at what particular moment a human life begins. However, we may well remember that the advances of modern science have also shattered many traditional assumptions about the exact moment of death. With our increasing scientific knowledge, the beginning as well as the end of life have become more difficult to define. Indeed, it is now very hard to pinpoint any specific moment for either. It seems that we need to know still more (and develop a more precise terminology) before we can really answer these difficult questions.
