With foreboding, Mammy had brought her young mistress a small package, addressed in a strange hand from New Orleans, a package containing a miniature of Ellen, which she flung to the floor with a cry, four letters in her own handwriting to Philippe Robillard, and a brief letter from a New Orleans priest, announcing the death of her cousin in a barroom brawl.

嬷嬷有所预感地给她的小主妇拿来一个从新奥尔良寄来的小包裹，上面的通讯地址是个陌生人写的，里面装着爱伦的一张小照（爱伦一见便惊叫一声把它丢在地上），四封爱伦写给菲利普？罗毕拉德的亲笔信以及一位新奥尔良牧师附上的短简，它宣布她的这位表哥已经在一次酒吧的斗殴中死了。

That now, [ 5 ] While time was, our first-Parents had bin warnd The coming of thir secret foe, and scap'd Haply so scap'd his mortal snare; for now Satan, now first inflam'd with rage, came down, The Tempter ere th' Accuser of man-kind, [ 10 ] To wreck on innocent frail man his loss Of that first Battel, and his flight to Hell: Yet not rejoycing in his speed, though bold, Far off and fearless, nor with cause to boast, Begins his dire attempt, which nigh the birth [ 15 ] Now rowling, boiles in his tumultuous brest, And like a devillish Engine back recoiles Upon himself; horror and doubt distract His troubl'd thoughts, and from the bottom stirr The Hell within him, for within him Hell [ 20 ] He brings, and round about him, nor from Hell One step no more then from himself can fly By change of place: Now conscience wakes despair That slumberd, wakes the bitter memorie Of what he was, what is, and what must be [ 25 ] Worse; of worse deeds worse sufferings must ensue.

但愿现在再来这一声，使我们的始祖父母受到警戒，知道他们的隐敌即将来临，可以尽早躲避，免入致命的陷阱！因为这时撒旦首次怒火燃烧，下到人间，做为人类控拆者之前的诱惑者，前来要把自己第一次失败和溃逃地狱中去的怨气一齐倾泻在脆弱、无辜的人类身上：他的大胆远征，勇敢沉着的成功既不能说可喜，也没有炫耀的理由，他正要着手一个险恶的阴谋，混乱的心胸，澎湃，沸腾，像产前的阵痛，像一架魔鬼的机械反跳过来，打在自己的身上。恐惧和疑虑在混杂的思想中抗争着，从底层扰乱了心中的地狱，因为从他心中带来了地狱，并且紧紧地缠绕着他自己，他不能踏出地狱一步，正像他不能离开他自己，也不能用转换地方的手段以求逃离。

I first saw him walking down the street in San Francisco the following week after hitchhiking the rest of the way from Santa Barbara in one long zipping ride given me, as though anybody'll believe this, by a beautiful darling young blonde in a snow-white strapless bathing suit and barefooted with a gold bracelet on her ankle, driving a next-year's cinnamon-red Lincoln Mercury, who wanted benzedrine so she could drive all the way to the City and when I said I had some in my duffel bag yelled "Crazy!"

我第一次见到他是在旧金山街头（离开圣巴巴拉之后我搭了一趟顺风车一路坐到旧金山，说来没人能信的是，载我的是位穿着件雪白的无吊带泳衣的年轻又可爱的金发美女，她赤着脚，脚踝上还戴着一个金脚环，开着最新款的肉桂色林肯牌"水星"轿车，她还说她想要点安非他命提提神好让她能一路开到旧金山而当我说我的圆筒形行李袋里就有一些的时候她大叫了一声："疯啦！"

In a caesium clock, the optimum frequency corresponds to 9,192,631,770 oscillations of the microwave per second (just over 9 GHz in frequency), so dividing the output electronically by this number provides one-second 'ticks' of the atomic clock.

对于铯原子钟，其最佳频率是微波每秒振动9，192，631，770次(频率略高于9 GHz)，而用电路把输出的信号除以这个数字就提供了原子钟的一声"滴答"。

With his hand over his mouth to choke back a cough, Antoine used to hear his mother bellow:"Suffer and die without speaking!"

有一次安托万用手捂住嘴巴尽量不咳出声来，就听到妈妈吼他：忍住！要死就悄悄地死。

Night after night the geese came lumbering in the dark with a clangor and a whistling of wings,even after the ground was covered with snow, some to alight in Walden, and some flying low over the woods toward Fair Haven, bound for Mexico. Several times, when returning from the village at ten or eleven o'clock at night, I heard the tread of a flock of geese,or else ducks, on the dry leaves in the woods by a pond-hole behind my dwelling, where they had come up to feed, and the faint honk or quack of their leader as they hurried off.

一夜夜，飞鹅在黑暗中隆隆而来，呼号着拍动着翅膀，一直到大地上已经铺了白雪之后，有的停在瓦尔登，有的低飞过森林到美港，准备上墨西哥，好几次，在十点十一点光景，从村里回到了家，我听到一群飞鹅的脚声，要不然就是野鸭，在我屋后，踩过洼地边林中的枯叶，它们要去那里觅食了，我还能听到它们的领队低唤着急行而去。

One more time I have to say Thank you for all your emails, support and compliments!!!

我还是想再一次的对你们发给我的邮件，对我的支持和赞美说一声谢谢！

Cover it with plenty of cold water and leave for approximately 20 minutes or until the grains soften and lose their crunchiness (which means, of course, you'll have to bite a few to find out how they're going).

再倒入大量的冷水，大约20分钟或者直到小麦颗粒软化为止和失去它们颗粒的脆声（当然，这意味着，你必须咬几粒数几次，来弄清解它们的变化情况）。

Then the son of Atreus drew his sword, and drove at the projecting part of his helmet, but the sword fell shivered in three or four pieces from his hand, and he cried, looking towards Heaven,"Father Jove, of all gods thou art the most despiteful; I made sure of my revenge, but the sword has broken in my hand, my spear has been hurled in vain, and I have not killed him."

阿特柔斯之子拔出柄嵌银钉的铜剑，高举过头，奋力劈砍对手的盔脊，却被撞顶得七零八落，脱离了手的抓握。阿特柔斯之子长叹一声，仰面辽阔的天穹："父亲宙斯，你的残忍神祗中谁也不可比及！我想惩罚亚历克山德罗斯的胡作非为，但我的铜剑已在手中裂成碎片，而我的枪矛也只是徒劳地作了一次扑击，不曾把他放倒！"
