Notes

Borealis:北极光---"北端的光"

由太阳风和地球磁场及上层大气交互作用产生。与南极光(aurora

australis)一起,统称为极光。auroraborealis这个词是由一个法国的

科学家PierreGasndi命名的。

:古希腊曙光女神

古希腊女神奥罗拉(也叫厄俄斯)是曙光女神，她在将光明带

往人间的时候，爱上了忧郁的特洛伊王子梯托诺斯，并将王子带

回了奥林匹斯山。月亮女神阿尔忒弥斯帮助她将王子藏了起来，

并告诉他去宙斯的神殿祈求王子得到长寿。奥罗拉向宙斯祈求了

王子的长寿，却忘记了祈求他的永葆青春。于是王子迅速地老去，

并被奥罗拉嫌弃，扔回了人间。但是奥罗拉为他生下了孩子，想

把孩子留在奥林匹斯，可是宙斯不同意。趁奥罗拉不在，宙斯把

孩子带回了人间，奥罗拉悲痛欲绝，却毫无办法。因为女神的悲

9

伤，世界失去了光明。最后奥罗拉被宙斯劝说，继续为人间带来

光明。

is:是指北部地区

Borealis与Australis相对,Australis是指南部地区。

起源:这个词是由希腊语Boreas而来,就是北风的意思。在希腊语

中,各个方向的的风都有属于自己的名字：Notus南风；Zephyrus西

风；Euro东风。

d：芬兰

芬兰位于欧洲北部，与瑞典、挪威、俄罗斯接壤，有“千湖之国”

之称。芬兰最早的居民为拉普人，故芬兰又称拉普兰。

dregion：拉普兰

拉普兰是芬兰最大、同时也是最北端的省份。拉普兰的旅游景点非常

有特色，且野生动物资源丰富，因此吸引了全球各地的人们前来观光。

拉普兰有着芬兰最富有盛名的国家公园，如圣诞村。此外，它还是观

测北极光的最佳地点之一。到此一游堪称是旅游的最高境界，终极追
