2. Sudden,
unseasonable rainfall. Wind. Lightning. A big tree falling over. Unexpected events.

突如其来、不合时宜的大雨,风,闪电,一棵大树轰然倒下,出乎意料的事件,等等。
3. It was a handsome room, with a fine marble fireplace facing the long sash windows, firmly closed against the
unseasonable chill.

这真是间华丽的办公室,用精美的大理石做成的壁炉正对着推拉式的窗子,将不合时令的寒冷紧紧关在外面。
