    The Nile（尼羅河）which is 6，450 kilometres in length（長度）is the longest river in the world． It has two tributaries（支流）in its up reaches，of which one is the White Nile rising on the
    East African Plateau， and the other is the Blue Nile rising on the Ethiopian Plateau． The two tributaries join in the Central Egypt into the Mediterranean．
