Birds Save Lives

  Bad weather can come up suddenly at sea. Winds and waves can smash (粉碎) boats. People may end up in the water. When that happens, there is no time to waste. Pigeons (鸽子) may be sent to the rescue (援救) .

  The pigeons are a special group of birds. The Navy is training (训练) these birds to look for the color orange in the water. That is because life jackets are orange.

  The pigeons ride in a helicopter (直升飞机) with the Navy crew (全体飞行员). The birds can see a very long distance-about 2000 feet. They usually spot (认出) the orange life jackets before the crew does. That means the crew can act more quickly to save people.

  Anything orange in the water gets the attention of the pigeons. The birds also find orange surfboards (冲浪板) that have been lost.

  I wonder if there is any girl or boy who does not like to see a rainbow (彩虹) in the sky. It is so beautiful.

  There is a story, saying that whenever you see a rainbow you should run at once to the place where it touches the ground, and there you would find a pot of gold. Of course it is not true. Neither you could find the pot of gold, nor could you ever find its end. No matter how far you run, it always seems far away.

  A rainbow is not a thing that we can feel with our hands as we can feel a flower. It is only the effect (结果) for light shining on raindrops. The raindrops catch the sunlight and break it up into all the wonderful colours which we see.

  It is called a rainbow perhaps because it is made up of raindrops and looks like a bow (弓).

  That is why we can never see a rainbow in a clear sky. We see rainbows only when there is rain in the air and the sun is shining brightly through the clouds. Every rainbow has many colours in the same order. The first or the top colour is always red, next comes orange, then green, and last of all blue. A rainbow is indeed one of the wonders of nature.
