In warmer parts of the world, groundhogs hibernate for as little as three months, but in colder regions their sleep can last six months or more.

在比较暖和的地区，土拨鼠只冬眠三个月，但是在寒冷地区冬眠则要持续六个月以上。

Chew on this: animal-rights group PETA says life in captivity is too stressful for groundhogs, which should thus be excused from Groundhog Day festivities.

仔细想想这些事实：动物权益保护组织声称土拨鼠的囚禁生活压力太大，因此在土拨鼠庆祝节时应当将它们放出来。
