Those trees are certainly spruces and firs.

那这些树自然就是云杉和冷杉喽。

The firs perspire a fine balsam of turpentine.

冷杉分泌出一种质地优良的松树胶。

The beams of our house are cedars; our rafters are firs.

以香柏树为房屋的栋梁、以松树为椽子。

Patches of hoarfrost under the firs sparkled rosy reflections.

冷杉下，斑斑点点的白霜闪耀着天空玫瑰色的映像。

Outside, the stars shone through the window above a jagged row of firs.

屋外，星光从一排参差的冷杉树梢上透进窗子。
