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 which we can feel with our hands as we can feel a flower. It is only the effect
(结果)of the light shining on rain-drops. 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 rain-bow 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.

What is colour? Why do some of the things around look red, some green, others blue?
Colours are really made by reflected
(反射)light. We see colour because most of the things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all lights, it is white. If it doesn't reflect any light, it is black.Some of the light is reflected and some is taken in
(吸收)and turned into heat. The darker the colour is, the less light is reflected, the more light is taken in. So dark-coloured(深色的)clothes are warmer in the sun than light-coloured clothes.(1) When something reflects light, we can _______.
