"It was like a WHOOOSH whoosh, then there was a fire and smoke, then I heard a second explosion"

"就'嗖'的一声，然后起火了，冒出了烟，再后来我就听见了第二次爆炸"

First introduced in 1966 on the flat-top acoustic Fender Wildwood which was a variation on the Freddie King guitar.

I soon found a way to convince him that I would do him no harm, and taking him up by the Hand laugh'd at him, and pointed to the Kid which I had kill'd, beckoned to him to run and fetch it, which he did; and while he was wondering and looking to see how the Creature was kill'd, I loaded my Gun again, and by and by I saw a great Fowl like a Hawk sit upon a Tree within Shot; so to let Friday understand a little what I would do, I call'd him to me again, pointed at the Fowl which was indeed a Parrot, tho' I thought it had been a Hawk, I say pointing to the Parrot, and to my Gun, and to the Ground under the Parrot, to let him see I would make it fall, I made him understand that I would shoot and kill that Bird; accordingly I fir'd and bad him look, and immediately he saw the Parrot fall, he stood like one frighted again, notwithstanding all I had said to him; and I found he was the more amaz'd, because he did not see me put any Thing into the Gun; but thought that there must be some wonderful Fund of Death and Destruction in that Thing, able to kill Man, Beast, Bird, or any Thing near, or far off; and the Astonishment this created in him was such, as could not wear off for a long Time; and I believe, if I would have let him, he would have worshipp'd me and my Gun: As for the Gun it self, he would not so much as touch it for several Days after; but would speak to it, and talk to it, as if it had answer'd him, when he was by himself; which, as I afterwards learn'd of him, was to desire it not to kill him.

可怜的星期五上次曾看到我用枪打死了他的敌人，但当时他站在远处，弄不清是怎么回事，也想象不出我是怎样把他的敌人打死的。可这一次他看到我开枪，着实吃惊不少；他浑身颤抖，简直吓呆了，差一点瘫倒在地上。他既没有去看我开枪射击的那只小羊，也没有看到我已把小羊打死了，只顾扯开他自己的背心，在身上摸来摸去，看看自己有没有受伤。原来他以为我要杀死他。他跑到我跟前，扑通一声跪下来抱住我的双腿，嘴里叽哩咕噜说了不少话，我都不懂。但我不难明白他的意思，那就是求我不要杀他。我马上想出办法使他相信，我决不会伤害他。我一面用手把他从地上扶起来，一面哈哈大笑，并用手指着那打死的小羊，叫他跑过去把它带回来。他马上跑过去了。他在那里查看小山羊是怎样被打死的，并感到百思不得其解。这时我趁此机会重新把枪装上了子弹。不久，我看见一只大鸟，样子像一只苍鹰，正落在我射程内的一棵树上。为了让星期五稍稍明白我是怎样开枪的，就叫他来到我跟前。我用手指了指那只鸟--现在我看清了，其实那是一只鹦鹉，而我原先把它当作苍鹰了。我刚才说了，我用手指了指那只鹦鹉，又指了指自己的枪和鹦鹉身子底下的地方，意思是说，我要开枪把那只鸟打下来。

A car backfiring, for instance, can set off an emotional response in a combat veteran if the loud noise becomes associated in his mind with a wartime experience.

比如，汽车爆胎会让退伍老兵产生情绪化的反应，只要他的脑子将这声巨响同战争中的某次经历联系在了一起。

A 21-year-old who spoke in a breathy, high voice, still lived at home, had his first, barely noticeable nose job and was a self-claimed virgin in an industry known for his hedonism, he was certainly an odd figure, but his personal life had yet to become intertwined with his public image.

这个21岁的大男孩儿，说话带着气声、尖嗓门；仍然住在家里；做了第一次几乎看不出的鼻部整容手术；身处这个人尽皆知的享乐为上的娱乐业中却声称自己纯洁无瑕。毫无疑问他是一个奇怪的人物，私生活却与公众形象始终纠结在一起。

Another time the attention of all was attracted by a little brown dog, with its tail in the air, who had come no one knew from where, and was running about fussily in front of the ranks. All at once a cannon ball fell near it, and it squealed and dashed away with its tail between its legs!

又有一次，所有的人都注意到了不知从哪儿冒出来的一只褐色的小狗，它把尾巴翘得高高的，满怀心事地迈着小碎步，跑到队伍前面，忽然，附近落下一颗炮弹，它尖叫一声，夹起尾巴，跳到一边去了。

Again I had to bite my tongue, this time to keep from giggling.

我不得不又一次咬住自己的舌头——但这次是害怕自己吃吃的笑出声来。

When the Second World War broke out in September, 1939, listeners to the BBG World Service waited to hear the sound of highflying planes and the crash of falling bombs as a backdrop to the hourly news broadcasts from London.

1939年9月，第二次世界大战爆发时，BBC国际台的听众们正等候收听作为发自伦敦的每小时整点的引擎声和炸弹落地的爆炸声。

In the early Paleozoic and Indosinian cycle, the tectonic movement is weak, and the rock has acoustic emission once, whose maximum paleo-stress is 13.3MPa and 24MPa, moreover the Majiang ancient reservoir is in the mainly accumulation period; the high frequency and intensity paleo-stress correspond to the Majiang ancient reservoir's reservoir comes into being or destruction. The single Neopaleozoic acoustic emission whose maximum paleo-stress is 92.6MPa means the reservoir comes into being.

在早古生代末期和印支期构造运动较弱，测试岩石的发声一次，古应力值分别为13.3MPa和24MPa，是麻江古油藏的主要成藏期；声发射次数较多或者古应力值较大时的时期，主要对应于麻江古油藏储层的发育期和油藏大规模破坏期。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
