英语翻译
人类史上,有很多次战争,无论战争是非与否,每一次都是生灵涂炭.
历史上十字军东征是西欧封建领主、意大利大商人和罗马天主教会,对地中海东岸地区发动的侵略性军事远征.宗教问题最终转化为战争,大量的掠夺财富,无情地杀戮,都给人们带来了不尽的灾难,人类似乎已经承受不起战争的恐惧.
然而,战争也给人类带来了很多好处,当然,这不仅不对战胜国而言.
比如最近的二战,科学家在国家的支持下,研制核武器,以掌握战争的主动权,虽然两颗原子弹给日本以毁灭性的打击,但在战后,闲置的技术被进一步开发,用于发电,潜艇动力等.还有坦克,炸药••••••无不是为适应战争而产生的,但现在却给人们带来了方便.
用一个不恰当的比喻,战争仿佛是科技的催生济,促进科技的发展进度.
