     We know the mosquito 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 likes the mosquito. But the mosquito may decide that she loves you. She? Yes, she. It's true

that male mosquito doesn't bite (咬) and 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. By the time the itching begins, and she

has flown away.

     And then what happens? Well, after her delicious dinner, the mosquito feels tired. She just wants to find a

place to have a good rest. There, on a leaf or a wall, she begins to lay eggs, hundreds of eggs.
