Thus saying, from her side the fatal Key, Sad instrument of all our woe, she took; And towards the Gate rouling her bestial train, Forthwith the huge Porcullis high up drew, Which but her self not all the Stygian powers [ 875 ] Could once have mov'd; then in the key-hole turns Th' intricate wards, and every Bolt and Bar Of massie Iron or sollid Rock with ease Unfast'ns: on a sudden op'n flie With impetuous recoile and jarring sound [ 880 ] Th' infernal dores, and on thir hinges grate Harsh Thunder, that the lowest bottom shook Of Erebus.

V1：她边说边从身边取出那不祥的钥匙――人间万祸的媒介，向着大门转动她的兽尾，巨大的格子吊闸，被高高地拔起来，那吊闸坚固、沉重，除了她，即使用全地狱天使的力量也动弹不了它；随后她把钥匙放进锁眼里，旋开了复杂的弹簧，轻轻松开所有铁铸石炼的门鼻、门闩，轰隆一声，地狱的大门忽然开了，由于用力过猛，所以造成反跳，使得门键上的粗厉声响如雷鸣，连地狱最深的底层也被震动了。

I heard a car engine purring smoothly.

I remember the arty prep well, as the guns were lined up behind us, and the noise was constant for quite a while, with the rumble kind of growing louder up and down the line as the different batteries were firing, and although we'd had some pretty impressive preps go out while we were at the sand wall, they were nothing like this.

我记得当时的炮火准备很充足，那时候火炮在我们身后一字排开，炮声持续了相当长的一段时间，随着不同炮兵连的射击轰隆声此起彼伏，尽管还没有出击时我们在沙墙的位置上就对此有所准备，但还是没有想象到会是这样。

The shouts of the Roman soldiery as they ran to and fro, and the howlings of the insurgents who were perishing in the flames, mingled with the roaring of the conflagration and the thundering sound of falling timbers.
