用英文介绍风筝的起源

原文：（欢迎追问!）
风筝真正的起源,现在已无法证明.有些民俗学家认为,古人发明风筝主要是为了怀念世故的亲友,
风筝
所以在清明节鬼门短暂开放,将慰问故人的情意寄托在风筝上,传送给死去的亲友.

　　风筝,古时称为「鹞」,北方谓「鸢」.大多数的人认为风筝起源于中国,而后广传于全世界,是一种传统的民间工艺品.实际上,中国最早出现的风筝是用木材作的.春秋战国时,东周哲人墨翟（公元前478-392年）,曾「费时三年,以木制木鸢,飞升天空……」.墨子在鲁山（今山东潍坊境内）,「斫木为鹞,三年而成,飞一日而败」.这是说墨子研究试制了三年,终于用木板制成了一只木鸟,但只飞了一天就坏了.墨子制造的这只木鹞是最早的风筝,也是世界上最早的风筝.（约公元前300年）,距今已有二千四百年.
　　直至东汉期间,蔡伦发明造纸术后,坊间才开始以纸做风筝,称为「纸鸢」.因此可以推断,中国风筝已有两千年以上历史了.
　　墨子把制风筝的事业传给了他的学生公输班（也称鲁班）,《墨子·鲁问篇》中说,鲁班根据墨翟的理想和设计,用竹子做风筝.鲁班把竹子劈开削光滑,用火烤弯曲,做成了喜鹊的样子,称为「木鹊」,在空中飞翔达三天之久.《书》上说：「公输班制木鸢以窥宋城」.
　　公元前190年,楚汉相争,汉将韩信攻打未央宫,利用风筝测量未央宫下面的地道的距离.而垓下之战,项羽的军队被刘邦的军队围困,韩信派人用牛皮作风筝,上敷竹笛,迎风作响（一说张良用风筝系人吹箫）汉军配合笛声,唱起楚歌,涣散了楚军士气,这就是成语“四面楚歌”的故事.
　　在正史中也有关于风筝的记载,时间较五代更早,其一是南朝的“侯景之乱”,梁武帝被侯景围困,城墙被包围.曾放风筝向外求援,据南史卷八十《侯景传》中所述,在梁武帝萧衍大清三年（公元549年）时,侯景作乱,叛军将武帝围困于梁都建邺（即今南京）,内外断绝,有人献计制作纸鸦,把皇帝诏令系在其中,当时太子简文在太极殿外,乘西北风施放向外求援,不幸被叛军发觉射落,不久台城即遭攻陷,梁朝从此也衰微灭亡.这是简文施放风筝向外求救不幸失败的故事.
　　相传在公元前五世纪时,希腊的阿尔克达斯就发明了风筝,可惜后来失传.直到公元十三世纪,意大利人马可波罗从中国返回欧洲后,风筝才开始在西方传播开来.
　　又从其它考据证实,约第十世纪传至韩国再至日本,十三、四世纪才传至欧洲.
　　美国也有放风筝的故事,当时的人们以为雷电与闪光,是宗教上神的怒吼而生恐惧,富兰克林则利用风筝,证明了雷电与闪光是空中放电的现象,而发明了避雷针.
