英文小作文：

Being born with anencephalia is a heartbreaking experience for any family. Without a developed brain, a baby cannot develop normally and may face many challenges in life. However, this condition is often the result of a genetic or environmental factor that can be difficult to predict or prevent.

In some cases, women may be at risk for anencephalia because they do not take folic acid before and during pregnancy. Folic acid is essential for proper brain development in the fetus, so it is important to take it regularly to reduce the risk of this condition.

On the other hand, fetal distress can also lead to anencephalia. This condition occurs when the baby is not receiving enough oxygen and nutrients during pregnancy. It is important to seek medical attention early if you or your baby is experiencing any signs of fetal distress.

In conclusion, being born with anencephalia is a rare but real condition that can have a profound impact on a family"s life. It is important to take precautions to reduce the risk of this condition, such as taking folic acid before and during pregnancy, and seeking medical attention if necessary.
