人教版的 Journey Down The Mekong
Several months before 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 the high altitude,the Mekong becomes wide，brown and warm.As it 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 the South China Sea.
