你能在雪地中开车不代表我们就能。 一年中唯一下雪的二天你就待在家里休息吧。 （南方很少下雪， 一年最多下个二三次， 但几乎每次一下雪就放假一天。）

Just because you can drive on snow and ice does not mean we can. Stay home the two days of the year it snows.

太二三22指著天起誓的，就是指著神的宝座，和那坐在其上的起誓。

Mt. 23:22 and he who swears by heaven swears by the throne of God and by Him who sits upon it.
