The Yeti (Abominable Snowman)
The Yeti is said to be a large, hairy animal that walks on two feet like a human being. The Yeti, or Abominable Snowman is an apelike animal cryptid, and the Yeti inhabits the Himalaya region of Nepal and Tibet.
The names Yeti are commonly used by the people indigenous to the region, There is the myth of the abominable snowman in the local area, and it is a part of their history and mythology. 21世纪教育网版权所有
There are various names for Yeti like “Abominable Snowman” which means “wild man” or Yeti, and “Kanchanjunga rachyyas” which means “Kanchanjunga's demon” in Nepal .21cnjy.com
Although the scientific community largely dismisses the Yeti as a fraud supported by legend and weak evidence, it remains one of the most famous creatures of cryptozoology; the study of unconfirmed animals.
The Abominable Snowman who haunts the imagination of climbers in the Himalayas seem to be hardly more elusive. The Yeti can be considered a Himalayan parallel to the Sasquatch or man-beast.【来源：21cnj*y.co*m】
【参考译文】
野人（雪人）
据说，野人是一种体型较大、全身长毛、能像人一样双脚站立行走的动物。野人，又称雪人是神秘的类猿动物。野人居住在尼泊尔和西藏的喜马拉雅地区。
雪人的名字是当地人常用的，在当地曾流传有喜马拉雅雪人的神话，这是他们的历史和神话的一部分。
在尼泊尔有各种不同的名称，比如：“Abominable Snowman (雪人)”的意思是“野人(Yeti )”还有“Kanchanjunga rachyyas”的意思是“阚婵俊嘎的恶魔”。
虽然科学界广泛认为雪人是欺诈的传说、缺乏证据的支持，但它仍然是一个神秘动物学最著名的动物；未经证实的动物研究。
常常勾起喜马拉雅山登山者遐想的雪人似乎并不那么令人难以捉摸。雪人可以被认为是一个喜马拉雅平行大脚野人或野兽。
