In the animal world, colour is of great importance to animals, birds and insects. Often it can s 1 their lives. Nature is beautiful, and we can see its beauty everywhere. Nature is full of colours. P 2, animals, birds and insects have many beautiful colours. Colour, however, for animals, birds and insects means not only beauty, it also means life to them because it helps them h 3 from other danger.
Some birds use their colours to tell other birds to s 4 away from their "houses" in the tree. They sing and move their wings to show their colours as a m 5 to other birds. One kind of butterfly is orange and black. Birds do not like e 6 them because they have a bad taste. Once a bird eats this kind of butterfly, it remembers the bad taste. After that, it will n 7 eat another orange and black butterfly!
Some moths(飞蛾) use colours to make birds a 8 of them. A bird can remember the colours or the marks on the moth's back. The bird sees the colours or the marks and doesn't eat the moth!

四、任务型阅读
There are many colours in nature. But do you know that a colour has weight? I think you'll say "no". But I am afraid you are wrong. If you don't believe, you may do a small experiment(实验).
First, put two objects with the same weight into two boxes. Then cover the box. Third, wrap(包裹) one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.
Why do you think so? A scientist found that different colours have different weights in a man's mind. So he did some tests and at last he got the result. That is to say, every colour has its own weight in our mind and their order is the same. The heaviest colour is red, then blue, green, orange, yellow and white.
The scientist told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientist say so? That is because every colour stands for a kind of light with a certain wavelength(波长). It reaches our brain through sense organs(感觉器官).
According to this discovery, scientists say that people accept the colours they like, and refuse the colours they hate. So your body and mind will be healthy by using the colours you like, or you'll be nervous or even get ill. For example, if you stay in a room with red windows, wallpaper and furniture for two hours, you'll feel you have been there for four hours. But if the room is blue, you'll feel you have been there for only an hour. Another example is that if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change with different colours.
| Discoveries | Examples | Reasons |
| Colours have 1 . | You may feel the red box is 2 than the white one, though they have the same weight. | Every colour has its own weight in our 3 . The heaviest one is 4 and the 5 one is white. |
| Colours have senses. | • The colour you like can make you 6 .• You'll feel time passes much 7 in the red room than in the blue one.• The colour will cause the 8 of your body temperature if you go from a red room into a blue one. | The 9 wavelength of each colour makes us feel the 10 of the colour. |
