What is colour? Why do some of the things around us 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 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, the more light is taken in. So dark-coloured(深色的)clothes are warmer in the sun than light-coloured clothes. 小题1:When something reflects light, we can_______.
A. A travel book B.A history book C. A popular science magazine C, An entertainment newspaper. 小题5:What’s the best title(题目)of this passage(短文)?
