They hang out in the treetops of central and south america .

他们出没在中美洲和南美洲地区，常挂在树梢上。

If I 'm outside I will sometimes keep my eyes open and focus on something fairly inactive , like the treetops .

如果我在室外，我有时会睁着眼睛，盯着一些完全不动的东西，比如树梢。

His army moved through the white trees of the gir forest like a silently approaching plague , and the pathetic little fortress of cooch naheen , seeing the advent of death in the rustling treetops , broke its own towers , ran up a flag of surrender , and begged abjectly for mercy .

他的部队穿过吉尔森林白色的树丛，像无声的瘟疫悄悄地逼近，库奇纳新这座凄惨的小城堡，即将见证婆娑作响的树梢死亡的来临，塔楼被毁，投降的旗帜会迅速升起，卑躬屈膝地祈求怜悯。

A laser like glas emits short , rapid-fire pulses of light and records the strength and speed of the return signals-the " echos " that ricochet from multiple levels of the forest , including treetops , lower branches , and the ground .

而像glas这样的激光器，（主动）发射出短波速射的脉冲光线，并记录回馈信号强度和速度从森林不同层级（比如包括树顶、低矮树枝以及地面）反射的回馈信号是不同的。

That reminded me of when I interviewed ang about " crouching tiger hidden dragon " in which actors seem to skip lightly over rooftops and hold a sword fight in treetops .

这令我想到就《卧虎藏龙》我对李安进行的参访，电影中的演员似乎轻轻一跃就上了屋顶，并在树梢上持剑对决。
