发出当的一声

As I sit at my window this summer afternoon, hawks are circling about my clearing; the tantivy of wild pigeons, flying by two and threes athwart my view, or perching restless on the white pine boughs behind my house, gives a voice to the air; a fish hawk dimples the glassy surface of the pond and brings up a fish; a mink steals out of the marsh before my door and seizes a frog by the shore; the sedge is bending under the weight of the reed-birds flitting hither and thither; and for the last half-hour I have heard the rattle of railroad cars, now dying away and then reviving like the beat of a partridge, conveying travellers from Boston to the country.

在这一个夏天的下午，当我坐在窗口，鹰在我的林中空地盘旋，野鸽子在疾飞，三三两两地飞入我的眼帘，或者不安地栖息在我屋后的白皮松枝头，向着天空发出一个呼声；一只鱼鹰在水面上啄出一个酒涡，便叼走了一尾鱼；一只水貂偷偷地爬出了我门前的沼泽，在岸边捉到了一只青蛙；芦苇鸟在这里那里掠过，隰地莎草在它们的重压下弯倒；一连半小时，我听到铁路车辆的轧轧之声，一忽儿轻下去了，一忽儿又响起来了，像鹧鸪在扑翅膀，把旅客从波士顿装运到这乡间来。

Decked out in her traditional garb — a long-sleeved and long-skirted dress that could have been a costume for a Victorian period drama if not for the hat, an oversized, cloth-covered pan with what appeared to bea baguette sitting on top - she culled disapprovingly through a bin of potatoes and harrumphed before she hiked up her prodigious skirts and walked out.

在她传统装束的外面覆盖着-一条长袖长裙体的衣服，如果不是那顶帽子，这身装束完全可以做为维多利亚时代戏剧的道具，而那顶帽子则是一个超大的、由布料遮盖着的盘子，顶部竖着一个看起来像法国棍子面包样的东西-她不以为然地在一筐马铃薯中挑拣着，当她拉起庞大的裙子站立起来时嗓子里发出哼哼声，然后走了出去。

当牛仔按动一只电钮开灯时，共鸣箱便开始发出嘟嘟声——牛仔要数的信号音的数目，是由灯光的颜色来确定的。

Even whilst we stare at the ragged horror of birds scattered broadcast, part-eaten, the soft, uneven cooing of the pigeon ripples from the outhouses, and there is a faint silver whistling in the bushes come twilight.

即使当我们凝视那些散落遍地、尸身不整的鸟儿腐烂而可怕的景象时，屋外也会飘来一阵阵鸽子的咕咕声，那从灌木丛中发出的微弱的啼鸣。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
