Fireworks date back to ancient China before the invention of gunpowder. 烟火起源于火药发明前的古代中国。

Fireworks made their way to Europe when Italian explorer, Marko Polo, brought them from the Orient in 1292. 在意大利探险家－－马可波罗－－于 1292 年将它们从东方带回时，烟火得以前进到欧洲。

And when they came to America, they brought their fireworks with them. 而当他们来到美国时，他们带着他们的烟火一起。

One such man was Vincenzo Sorgi, who came to America in 1899. In 1902, he started the American Fireworks company. 这样的一个人是 Vincenzo Sorgi，他在1899 年来到美国。在1902 年，他创立了美国烟火公司。

After all, these pyrotechnicians are handling explosives, and enjoying every bit of it. 毕竟，这些烟火专家正在处理的是爆裂物，并且享受其中的一点一滴。

At first, of course you get the jitters, but then that all works out. And now, it's show time. 起初，当然你会有些紧张不安，但然后那一切都顺利进行。而现在，好戏上场了。

Eric said that in his 10-plus years of experience with pyrotechnics,  Eric 表示，在他十多年来的烟火经验中，

fireworks displays choreographed with music are hands down the favorite with Americans. 加上音乐编排的烟火表演毫无疑问是美国人的最爱。

While pyrotechnic crews will at times still light the shells by hand, most of them are ignited electronically, which makes them safer. 尽管烟火技术员们有时仍会手动点燃抱弹，但大多数抱弹是电子引燃的，那使它们更加安全。

Like the Colonial Beach show, it's all done by switch panel. 像殖民海滩这场表演，一切就是经开关控制板完成的。

What makes a perfect show would be when the show goes off flawlessly, and the crowd goes crazy at the very end of the show. 成就一场完美演出的，会是当表演完美无瑕地进行，然后群众在演出的最后一刻陷入疯狂之时。

Today, we celebrate our country's independence, and we'll end our celebration with this spectacular fireworks display, 今天，我们庆祝我们国家的独立，而我们会用这场壮观的烟火演出为我们的庆祝结尾，

just as those early patriots did over 200 years ago. 就像超过两百年前那群早期的爱国者们做的一样。
