We know mosquitoes 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 mosquito. But the mosquito may decide if she loves you. She? Yes, she. The male(雄性) mosquito doesn’t bite! Only the female(雌性)mosquito bites because she needs blood(血)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 others!

If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly 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.
