    　　What is colour？ Why do some of the things around us look red, some green, others blue？

    　　Colours are really made by reflecting (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 light, 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 (变成) heat (热能). The darker the colour is, the less light is reflected and the more light is taken in. So dark-coloured (深色的) clothes are warmer in the sun than light coloured clothes.

    1．What can we see when something reflects light？

    _______________________________________

    2．Why does something look white？

    　　Small children like to eat snow. Sometimes they make snow cones (圆锥状的东西) . But eating snow can be dangerous. The snow may be full of lead (铅) .

    　　The air in cities has a lot of lead in it. Country air may have less. Most of the lead comes from cars. Snow falls and it soaks (吸收) up the lead from the air. More lead is trapped in the snow on the ground.
