水
Water Water is the "life food" of our earth. It is in every living thing. It is in the air. It runs through mountains and valleys. It forms lakes and seas. Nature has a great water system. Rainwater finds its way to rivers and lakes. River water runs into the sea. At the mouths of the rivers, fresh water joins the salt water of the sea. Here at the mouth of a river, there is very important plant and animal life. But pollution destroys this life. We have to clean our rivers. Man has to work with nature, not against it.
水 水是地球的生命之源。它存在于一切生物中，存在于空氣中。它穿過(guò)山脈，流過(guò)山谷，匯成河流海洋。 自然界有龐大的水系統(tǒng)。雨水流入江湖，然后河水流入海洋。在江河的出海口，淡水與海水交匯，這里還生長(zhǎng)著很重要的植物和動(dòng)物。但是污染使它們死亡。我們必須清潔河流。 人類一定要順應(yīng)自然，不要違背自然。
