Trees thickened around him, oaks and poplars, some hemlocks.

周围的树木很繁茂，橡树、杨树还有铁杉。

Although both feed by draining the hemlocks of their juices, the adelgids also inject toxic chemicals into the trees.

虽然它们都依靠吸铁杉的树汁存活，但球蚜同时还把有毒的化学液体注进了树木。

These hemlocks whispered over his head, these hickory logs were his fuel, and these pitch pine roots kindled his fire;

铁杉在樵夫的头上耳语，山核桃是他的燃料，还有松脂的松根供他点火；

Now they had skated out the bed of brook and arrive at another glacier, Banks of the glacier were full of interlaced tall firs and hemlocks, the shade covered the moonlight, the sky was pitch-black.

他们这时候已经滑出了融雪不多形成的溪床，来到另一条冰河上，河两岸布满了树枝交错的高大冷杉和铁杉，树影遮住了月光，冰河上空似乎一团漆黑。
