No one likes the mosquito. But the mosquito may decide if she loves you. She? Yes, she. The male
mosquito doesn"t bite! Only the female mosquito bites because she needs blood to lay eggs. She is always
looking for things or people she wants to bite. If she likes what she finds, she bites. But if she doesn"t like
your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites you, just
remember you are chosen. You"re different from the others!
If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly
and quietly that you may not feel anything different. After she bites, you will have an itch(痒) on your body
because she puts something from her mouth together with your blood. When the itch begins, she has flown
away.
And then what happens? Well, after her delicious dinner, the mosquito feels tired. She wants to find a
place to have a good rest. There, in a tree or on a wall, she begins to lay eggs, hundreds of eggs.

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(庄稼). When crops
are green, locusts look green. But as the harvest(收获) 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. This is
because they have the colours much like the trees.
Have you ever found 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.

And they can eat small animals. One famous meat-eating plant is the Venus flytrap (捕蝇草).
The Ven
us flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs.
If a fly touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the
leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some
places, the ground is very poor. It doesn"t have all these important things, especially nitrogen (氮).
Animal meat has a lot of nitrogen,
so some plants eat meat to get what they need. Let"s hope that some of the bigger plants don"t get the same idea!
