16、澜沧江的地方长大，澜沧江就是在其他国家被称为湄公河的在中国的那一段河流。王薇很快使他们也对骑自行车感兴趣了。大学毕业后，我们终于有骑自行车旅行的机会了。我问姐姐，“我们要去哪里？”正是我姐姐提出骑自行车从湄公河源头一直到它的尽头的想法。现在她正在安排我们的旅行时间表。我很喜欢我的姐姐，但是她有一个严重的缺点。她有时真的会很固执。尽管她对到某些地方的最佳路线并不清楚，她还是坚持认为自己把这次旅行安排得很妥当。如今，我了解了她总是一意孤行。我老是问她，“我们什么时候动身？什么时候回来？”我问她是否看过地图。当然，她并没有看过；我姐姐是不会在意细节问题的。于是，我告诉她湄公河的源头在青海省。她给了我
17、一个坚定的眼神表明她是不会改变主意的。当我告诉她我们的旅程将从海拔5 000多米的地方开始时，她似乎显得很兴奋。我告诉她那儿空气稀薄，呼吸困难，而且天气很冷时，她却说那将是一次有趣的经历。我很了解我的姐姐。一旦她下了决心，什么也不能使她改变。最后，我只得让步。在我们旅行前的几个月，我和王薇去了图书馆。我们找到了一本大型地图册，里面有一些世界地理的明细图。从地图上可以看到，湄公河发源于西藏一座山上的冰川。起初，河面很小，河水清澈而冷冽。然后，它开始快速流动。它穿过深谷时就变成了急流，流经云南省西部。有时，这条河进入宽阔的峡谷形成了瀑布。我们俩惊奇地发现这条河有一半是在中国境内。当流出中国，流出高
18、地后，湄公河就变宽了，变暖了，河水也变成了黄褐色。当它进入东南亚后，流速减缓。河水蜿蜒缓慢地穿过低谷，流向生长稻谷的平原。最后，湄公河三角洲的各支流流入南海。JOURNEY DOWN THE MEKONG JOURNEY DOWN THE MEKONG PART 2 A NIGHT IN THE MOUNTAINS PART 2 A NIGHT IN THE MOUNTAINSAlthough it was autumn，the snow was already beginning to fall in Tibet.Our legs were so heavy and cold that th

24、你看见过雪人骑自行车吗？我们看上去就是那样。在路上身穿长羊皮大衣的孩子们停下来看我们。在下午晚些时候我们发现天气太冷了我们的水杯都结冰了。可是，湖面在落日的余晖下像镜子一样发光，看上去美极了。王薇像平常那样骑在我前面。她非常可靠，我知道我不用鼓励她。上山很艰难，但是当环视四周，我们惊讶于眼前的景色。我们似乎能够看到数里之外。到了某一点我们的位置太高了我们发现我们正在云里骑车。然后我们开始骑车下山。这非常有趣，尤其是天气变得越来越暖和。在山谷中我们发现很多色彩鲜艳的蝴蝶在我们周围飞来飞去，并且我们看到很多牦牛和羊正在啃食青草。在这里我们要把帽子、外套、手套和裤子换成衬衫和短裤。刚到傍晚我们就要停下扎营。我们安好帐篷然后吃饭。晚饭后王薇倒头便睡，但是我却睡不着。午夜时分天空变得晴朗了，星星变得更加明亮了。周围如此安静。几乎没有风只有我们的营火做伴。躺在这星空下我在想我们已经走了多远了。我们很快就要到云南大理了，在那里我们的表兄道伟和于航会加入我们。我们迫不及待地想要见到他们。课时作业课时作业点击进入链接点击进入链接
