LEARN IN CONTEXT

Read and listen across several real contexts

This lesson uses the number and type of texts that fit the topic. Learn the same language across different situations instead of forcing everything into one dialogue.

为什么同一条河两岸景观不同

一条河穿过山地进入平原后,水流速度、河床宽度和岸边植被都会发生变化。在较陡的上游,水流常把细小泥沙带走;到了地势平缓的下游,部分泥沙逐渐沉积,河岸附近更容易形成湿地。几枝耐水植物可能只是局部现象,不能单独代表整个流域。
解释自然景观时,需要同时看地形、气候、水文和人类活动。某一年降雨异常也可能把河岸形态改变得很明显,因此研究者通常比较多年记录,而不是只根据一次观察下结论。

野外观察记录

地点A
峡谷上游,坡度大,石块多,水流快
地点B
河谷出口,河道变宽,细沙增多,岸边有成片芦苇
限制
两次观察都在夏季,尚不能说明全年规律
