土拨鼠

He is dispatched to Punxsutawney, Pa., to cover the festivities of Groundhog Day, on which Punxsutawney Phil, the groundhog, is awakened from his slumbers and studied to discover if he will see his shadow.

那里有一只与他同名的土拨鼠菲尔，将在那天从冬眠中醒来，并且向人们汇报他是否看见了自己的影子。

On the morning of February 2, Groundhog Day in Punxsutawney, Phil is invited to step out of his lair. If he sees his shadow, in other words if the sky is clear and bright, local people believe -- or at least they profess to believe -- that there will be another six weeks of hard winter. If Phil casts no shadow because the sky is overcast, the prognosis is for mild weather and an early spring.

在2月2日，也就是彭瑟托尼镇的土拨鼠节的上午，人们请菲尔走出它的窝，如果它能看到自己的影子，也就是说天空晴朗无云，当地人就会相信（或者说至少他们表示相信）未来还有6周的寒冬；如果是阴天，菲尔没有投下影子，就预示着天气温煦，春天早到。
