Benny, I translated another two paragraphs into Chinese, please see if they are correct:

Originally these terracotta soldiers were equipped with real weapons, weapons that have mainly disintegrated when the farmers made their find. But Archeologists did find metal remnants of these weapons scattered around the figures. Out of the dust emerged sword blades that were still sharp after two millennia. They also uncovered intricate bronze crossbow triggers; these mechanisms were precision engineered using a technology 13 hundred years ahead of their time and were as complex as modern rifle bolts. 2000 years ago, no other people on earth had anything near the technology to produce even one of these triggers, let alone the hundreds of thousands the emperor had mass produced for his army. With these crossbows, Chinese troops became the most feared in the world.

原来这些兵马俑装备好了真正的武器，农夫发现的时候，大部分的武器已土崩瓦解了。但考古学家就找到这些武器的金属残在雕像周围散落了，灰尘中出来的剑刃即使过了两千年也依然锋利。他们还发现了复杂的青铜弩扳机；这些机械装置使用领先于他们所处的时代达一千三百年的一项科技精密设计的，和现代的步枪栓一样复杂。两千年前，世界上没有任何其他人有任何相近的技术能生产出一个这样的扳机，至于像皇帝那样成千上万地生产出来给他的军队就更不必说了。由于装备了弩，中国的军队变成了世界上最令人恐惧的军队。

Thousands of years later, Chinese soldiers were still using crossbows against the British invaders. In the 19th century it may have been an outdated weapon but 2000 years ago the crossbow was one of the most high-tech inventions the world had ever seen.

数千年后，中国士兵还在使用弩击英国侵略者，在十九世纪这种武器可能是已过时的，但是两千年前弩是在世界上所见过的最高科技的发明。

Thanks!
