Midsummer on the tundra and the sun does not set.
現(xiàn)在是苔原的仲夏時(shí)節(jié)，不會(huì)出現(xiàn)日落
At these latitudes the sun's rays are glancing
在這個(gè)高緯度地區(qū)，太陽(yáng)輻射只能斜射到這片土地
and not enough of their energy reaches the ground to enable trees to grow.
到達(dá)地面的能量很少，并不足以支持樹(shù)木生長(zhǎng)
You'll need to travel 500 miles south from here before that is possible.
由此往南500英里的地方才有可能生長(zhǎng)著樹(shù)木
These stunted shrubs mark the tree line -
這些矮小的灌木標(biāo)志著森林界線(xiàn)
the beginning of the boreal forest - the taiga.
北方森林由此開(kāi)始，這就是泰加林帶
The needle-shaped leaves of the conifers are virtually inedible
針葉樹(shù)的針狀樹(shù)葉根本不能食用
so this forest supports very little animal life.
所以生活在這片森林里的動(dòng)物非常稀少
It's a silent place where the snow is unmarked by footprints.
這是個(gè)寂靜的地方，雪地上沒(méi)有被踩過(guò)的腳印
In the Arctic winter snow forms a continuous blanket across the land.
每到北極冬季，雪便為這片土地蓋上一層廣袤無(wú)邊的銀毯
But as spring creeps up from the south the taiga is unveiled.
可是隨著春天漸漸從南方趕來(lái)，泰加林帶也揭開(kāi)了它的面紗
