It is the worlds 12th-longest river and the 7th-longest in Asia. Its estimated length is 4,350 km (2,703 mi), and it drains an area of 795,000 km2 (307,000 sq mi), discharging 475 km3 (114 cu mi) of water annually From the Tibetan Plateau this river runs through Chinas Yunnan province, Burma (Myanmar), Laos, Thailand, Cambodia and Vietnam. In 1995, Laos, Thailand, Cambodia and Vietnam established the Mekong River Commission to assist in the management and coordinated use of the Mekongs resources. In 1996 China and Burma (Myanmar) became “dialogue partners“ of the MRC and the six countries now work together within a cooperative framework. The extreme seasonal variations in flow and the presence of rapids and waterfalls in this river have made navigation difficult. The river is a major trading route linking Chinas southwestern province of Yunnan to Laos, Burma (Myanmar) and Thailand to the south, an important trade route between western China and Southeast Asia. 湄公河（Mekong River） ， 干流全长 4180 公里1， 是亚洲最重要的跨国水系， 世界第十长河流 1，亚洲第七长河流 1；主源为扎曲，发源于中国青海省玉树 藏族自治州杂多县。流经中国云南省、老挝、缅甸、泰国、柬埔寨和越南，于越 南胡志明市流入南海。 流域除中国和缅甸外， 均为湄公河委员会成员国。 湄公河 上游在中国境内，称为澜沧江，在柬埔寨语作Mekong（湄公， “ 母亲” 的意思） ， 越语作 S?ng M K?ng(湄公河 ) / C ?u Long Giang(九龙江 )，下游三角洲在越南境 内，因由越南流出南海有9 个出海口，故越南称之为九龙江。 由于湄公河在旱季及雨季的流量有极大变化，以及主干流有不少激流及瀑布， 造 成湄公河的船只通航能力十分困难。目前湄公河只有下游550 公里可通航。Step 3 Learn the passage by yourself and try to finish the following questions. 自主预习课文、完成下列问题 提示： 课文预习三遍。 第一遍了解文章大意。 第二遍试着独立完成1、2、3 小题。 第三遍试着小组讨论完成4、5 题。1、What was Wang Kun and Wang Wei s idea of a good trip? 2、Who planned the trip to the Mekong? 3、Where is the source of the Mekong and which sea does it enter? 4、What difficulties did Wang Kun and Wang Wei find about their journey? 5、What do you think about Wang Kun and Wang Wei?
