Whoever you are or wherever you come from， one thing is clear： you know the mosquito（蚊子）very well. Mosquitoes fly everywhere. They can be found almost all over the world， and there are more than 2，500 kinds of them.
No one loves the mosquito. But the mosquito may decide that she loves you. She? Yes. It is true that only the female（雌性的）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 more delicious. Next time a mosquito bites you， just remember that you are chosen. You are 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 have known anything is happening. After she bites， you will have an itch（发庠）on your body because she puts something from her mouth together with your blood. By the time the itching begins， she has gone.
And then what happens? Well， after her delicious dinner， the mosquito feels tired. She just wants to find a place to rest. There， on a leaf or a wall， she begins to lay eggs， hundreds of eggs!
