你曾见过一河流吗?这条河是一条流动的大溪流。这条河就是密西西比河。 它流经整个美国。

Look at this map of the United StatesIt shows where the Mississippi River beginsand ends. Let's follow the Mississippi Riveron its long journey

看看这张美国地图。它说明了密西西比河的起点和终点。 让我们跟随密西西比河做一次长途旅行吧。

Where a river begins is called its source. The Mississippi River begins in a lakein Minnesota. It starts out as a small, clear stream.

河流的起源地叫做源头。密西西比河的源头是明尼苏达州的一个湖泊。它流出时是一条小而清澈的小溪。

Other small streams flow into the Mississippi River. The river gets biggerand faster. At the Falls of St. Anthony, the river flows through locks. Locks raiseor lower the water, helping boatsto travel on the river.

其他小溪也流进密西西比河。河水变得更宽更急。在圣安东尼瀑布处，河水流经水闸， 水闸能升高或降低水位，帮助船泊在河上行驶。

The Mississippi River flows downto lower land. It flows more slowly overthe flat land. It begins to wind backand forth. The flat land around the riveris called its floodplain.

密西西比河流向地势较低的地方。它流经平地时流得更慢。 它开始蜿蜒曲折流淌前进。被河水围住的平地称为漫滩。
