What is color? Why do some of the things around us look red, some green, others blue? Colors are really made by reflected(反射) light. We see colors because most of 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. Some of the light is reflected and some is taken in (吸收) and turned into heat(熱能). The darker the color is, the less light is reflected, and the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.

1.When something reflects light, we can .

A.see its color B.see its heat C.not see its color D.see nothing

2.Something looks white because it reflects .

A.some light B.no light C.all light D.most light

3.In summer make people feel cool.

A.dark-colored clothes B.red colored clothes

C.green-colored clothes D.light-colored clothes
