Although bears mate in the spring, the fertilized eggs don’t begin to develop until the females return to the den for the winter.
虽然熊在春天交配，但是受精卵直到冬天雌熊返回洞穴才开始发育。
The females must have stored up enough fat over the summer to support themselves and their developing cubs over the long winter.
雌熊必须在夏季储存足够的脂肪好让自己和正在发育的幼仔安然过冬。
If not enough fat is stored, the embryos won’t develop at all, and the female bear won’t produce any cubs that year.
如果储存的脂肪不充裕，胚胎就无法完全发育，那么这一年雌熊也不会诞下任何幼仔。

Contrary to popular belief, bears don’t eat humans.

Unless humans surprise the bear or threaten the cubs, bears will avoid human contact.
除非受到惊吓或幼仔受到威胁，否则它们会尽量避免与人类接触。
