[audio]http://sound.yywz123.com/tingbbs/voa/voa20120730.mp3[/audio]A miscarriage is the natural loss of a baby before the twentieth week of pregnancy. Experts say many pregnancies end before a woman even knows she was pregnant. Up to twenty percent of known pregnancies end in a miscarriage. Miscarriages are generally caused by genetic problems with the baby that prevent it from developing. 流产是怀孕前20周的一种自然淘汰。专家说，许多妊娠在孕妇知道自己已经怀孕前就已经结束。多达20%的已知妊娠会发生这种情况。
