What is color? Why do some of the things around us look red, some green, others blue?      Colors are really made by reflected light (反射光线). We see colors because most of the things reflect light. Something is red, because 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. The darker the color is, the less light is reflected and the more light is taken in. So dark-colored (深色的) clothes are warmer in the sun than light-colored (浅色的) 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. less light

3. The dark-colored clothes are warm because _____ is taken in.
