There're many different kinds of colour in the world, such as white, blue, orange, red, and so on. But my favourite colour is green.
     I think green is the most beautiful colour. Do you know why? Because green is the colour of life. Do you think so?
     As you know, most alive plants are green, like grass and trees. Green is good for our eyes, too. When your eyes are very tired, you will watch the green trees or green grass, they can help you to relax your eyes. And I think green is the nature colour, I love nature things.
     Can you tell me what your favourite colour is?
