《劝学》这首诗的英文翻译

seveal months befors our trip,wang wei and i went to the library. We found a large atlas with good maps that showed details of world geography. From the atlas we could see that the Mekong River begins in a glacier on a Tibetan mountain. At first the river is small and the water is clear and cold .THen it begins to move quickly.It becomes rapids as it passes through deep valleys,travelling across western Yunnan province. Sometimes the river becomes a waterfall and enters wide valleys. We were both surprised to learn that half of the river is in China. After it leaves China and high altitude, the Mekong becomes wide,brown and warm. Asit enters southeast Asia, its pace slows. It makes wide bends or meanders through low valleys to the plains where rice grows. At last, the river delta enters southe China sea.
