“Mother, may I go down to the river? It has stopped raining now!”

“Very well, Tom,” replied his mother, “only, be careful, and don’t stay away long!”

So, Tom ran off down the field to the river which flowed past his father’s farm in far north Queensland in Australia. It had been raining for ten days. Sometimes the rain fell fast and hard, then light showers would follow. The ground was all wet.

“All hot countries, such as where we live,” Tom’s father had once told him, “may flood at times. The sun has great power in the tropics to draw up the water from the sea. You know how the vapour rises into the air. The higher the temperature of the air, the greater the amount of moisture(水分) the air can hold. When the air cools, the vapour becomes clouds, or if it is near the earth’s surface, as mist(薄雾). When the air cools gradually(逐渐地), the rain drops are small and the rain is light. However, when the vapour drops suddenly in temperature, the drops are large and the rain is heavy.”

“In some tropical countries, where the sun is always at work on large bodies of water, a very large amount of vapour collects in the air, and it may take days, or even weeks, to form rain drops and fall. It may then rain for days continually. When this happens, after two or three days, the water falls does not have the time to soak(浸泡) through the soil or be carried off in the streams; so it gathers on the surface, and then we have a flood.”

When Tom got to the river, where the crossing was, he found the water rising rapidly. He thought about what his father had taught him about the floods, and decided to go back home at once and tell him the news.
