Do you know why different animals or pests have their special colours? Colours in them seem to be used mainly to protect themselves.

Some birds like eating locusts,but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the coloursof crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown colour as crops have. Some other pests with different colours from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal life, you’ll find the main use of colours is protecting themselves. bears, lions and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colours much like the tree.

Have you ever noticed an even more strange act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spread over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn’t strong at all.

If you go to a fast food restaurant, you will probably see a lot of teenagers. Today, many teenagers are overweight, and reason of this is because of their bad eating habits. Most teenagers love fast food with a lot of fat, oil, salt and sugar. People often call this kind of food “junk food”.

But bad eating habits go beyond fast food. We find many teenagers eat unhealthily. Some don’t have breakfast before they go to school. During the day, some don’t have a proper meal for lunch. In a recent survey at one school, scientists found that over two thirds of the students didn’t follow a healthy diet. They didn’t like vegetables, and many of them didn’t like to eat fruits. They preferred to eat food with a lot of salt, sugar, or fat.

Parents today also worry about their children’s diet. Some doctors give the following advice:

Teenagers shouldn’t eat too much junk food.

Teenagers shouldn’t eat food with too much salt. Salt can cause high blood pressure(高血压)in the future.

Teenagers should eat food with less fat, oil, and sugar.

Teenagers need to eat some fruits and vegetables every day. Fruits and vegetables are rich in vitamins(维生素)and have little fat.

Teenagers need to drink more milk. Milk will help their bones grow.

Teenagers need to eat breakfast every day. This is good for their body and mind.
