His hoary hair loooked like hoarfrost.

他灰白色的头发看起来像白霜。

Not till I saw what looked like hoarfrost dropping from the side of the Fall was the problem explained.

直到我看到看起来像白霜从瀑布边掉下来的东西， 问题才得到解释。

The huge trees stood there leafless and covered with hoarfrost; the beautiful hedgerows which surrounded the old churchyard wall were withered; and the gravestones, half covered with snow, were visible through the openings.

高大的树木光秃秃地立在那里， 上面覆盖着白霜。围绕着旧墓地墙的漂亮篱笆已经枯萎了。从洞口可以看到一半被雪覆盖的墓碑。

There was a slight hoarfrost that night, and the moon, though not more than half full, threw a spirited and enticing brightness upon the fantastic figures of the mumming band, whose plumes and ribbons rustled in their walk like autumn leaves.

晚上下了一点儿白霜，月亮虽然还没有半圆，却还是在假面剧团这些装扮怪异的演员身上撒下生动活泼、充满诱惑的银光，在他们行进时，彩羽绸带就像秋天的树叶一样，发出沙沙声响。
