Unit 3 The World of Colours and Light

Welcome to the unit

一、话题背景导读

Light is everywhere in our world. We need it to see: it carries information from the world to our eyes and brains. To see colours, there must be at least a little bit of light. While light is in fact made of all colours, but the colours we see depend on the quantity and colour of light being thrown back (reflected) or taken in (absorbed) by an object. In order for humans to see colour, the reflected light goes to sensitive area in the back of our eyes called the retina (视网膜) which sends impulses to the brain which then interprets the combination of impulses to be the colour humans see.

All of the colour on a printed page can be produced with the three pigment (色素) primaries, red, blue, and yellow. There are also called the subtractive primaries because together they make black.

Combinated in pairs, they yield another set of primaries, the additive, or light ,primaries. These are the wavelengths of orange-red, blue-violet, and green that combine to make white light. This is how the colour non your computer monitor behaves. When these colours are all combined in pairs they form, red, blue, and yellow. That light is made up of colour----that , in away, colour is light, and energy.

Human beings feel a universal attraction to light. It is the source of life-giving energy…. And where there is light there is colour. Answer the following questions:
