请将下面这段话翻译成英文：

　　灯笼(lantern)又称为灯彩，起源于1800多年前的西汉时期。在古代，灯笼的主要作用是照明。现在，灯笼综合了绘画艺术、剪纸(paper cutting )、纸扎、刺缝(seam)等工艺，已经变成了一种供收藏与欣赏的传统工艺品。每逢佳节庆典到处都可以看到灯笼，特别是元宵节和中秋节，人们都挂起象征团圆意义的红灯笼，来营造一种喜庆的氛围。后来在中国灯笼就成了喜庆的象征。

　　四级翻译参考译文：

　　1.起源于:可译为originate from。也可以翻译为derivefrom，但这个词组常用被动形式。

　　2.西汉时期:应译为Western Han Dynasty,除了西汉，还有如北宋、南宋、东晋等这样的朝代名，翻译时“东西南北”这四个字分别要译为Eastern, Western, Southern,Northern。此外，还有后汉、后周这样的朝代名，其中的“后”应翻译为Later。

　　3.传统工艺品:应译为traditional art and craft。

　　4.元宵节和中秋节:“元宵节”翻译成the Lantern Festival, “中秋节”翻译 成the Mid-Autumn Festival。由于这里不是指特定的某一个元宵节或中秋节，所以Festival要采用复数形式，表示“每逢…”的意思。

　　5.…的象征:可译为the symbol of...symbol有“象征;符号”的意思。
