    Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew: 1.5 meters (4 feet) in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1,000 kinds of bamboo.

    Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters (1 foot) across. This plant also comes in different colors, from yellow to black to green.

    Bamboo has been used to make many things such as hats and kitchen tools (厨房用具). Because it is strong, bamboo is also used to build buildings.

    Many Asian countries have used bamboo for hundreds of years. They often use bamboo for buildings and supporting (支撑) new buildings and bridges while they are being built.

    In Africa, poor farmers are taught how to find water using bamboo. These African countries need cheap way to find water because they have no money, and their fields often die from no rain and no water. Bamboo pipes (管子) help poor farmers bring water to their thirsty fields without spending a lot of money.

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

　　Some birds like eating locusts(蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colours together with the change of the colours of 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 colouring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters(猎人). This is because they have the colours much like the trees.

　　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(液体) when it faces danger. While the liquid spreads over(散开), its enemies(敌人) cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.
