喜马拉雅山脉(Himalayas)，亦称the Himalaya。
是亚洲南部的山系。它在北面的西藏高原和南面的印度次大陆平原之间筑起了一道屏障。它组成了地球上最大的山系，拥有三十座海拔超过7,300米的山峰，包括埃佛勒斯峰。山脉东西长达2,400公里，总面积约595,000平方公里。传统上从北到南把它分成四个平行区域：横喜马拉雅山脉、大喜马拉雅山脉（包括主峰）、小喜马拉雅山脉（包括2,000～4,5000公尺的次峰）以及外喜马拉雅山脉（包括最低的那些山峰）。在宽广的喜马拉雅弧区的东西两端之间有几个印度的邦以及尼泊尔和不丹王国。这个山脉就像是一条巨大的气候分界线，在印度一侧产生大量的雨雪，而另一侧西藏却很乾燥。在该山脉的许多地方实际上是不可逾越的，即使飞机也飞不过去。山脉的冰川和积雪是十九条主要河流的源头，包括印度河、恒河和布拉马普得拉河。

Himalayas
Mountain system, southern Asia. It forms a barrier between the Tibetan Plateau to the north and the plains of the Indian subcontinent to the south. It constitutes the greatest mountain system on earth and includes 30 mountains rising to heights above 24,000 ft (7,300 m), including Mount Everest. The system extends some 1,500 mi (2,400 km) from east to west and covers about 230,000 sq mi (595,000 sq km). It is traditionally divided into four parallel ranges: from north to south, the Trans-Himalayas, the Great Himalayas (including the major peaks), the Lesser Himalayas (including peaks of 7,000-15,000 ft, or 2,000-4,500 m), and the Outer Himalayas (including the lowest peaks). Between the eastern and western extremities of the broad Himalayan arc lie several Indian states and the kingdoms of Nepal and Bhutan. It acts as a great climatic divide, causing heavy rain and snow on the Indian side but aridity in Tibet, and represents at many points a virtually impassable barrier, even by air. The mountains' glaciers and snows are the source of 19 major rivers, including the Indus, Ganges, and Brahmaputra.
