    We 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 likes the mosquito. But the mosquito may decide that she loves you. She? Yes, she. It's true
that the 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 other people!    
     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 on your body
because she puts something from her mouth together with your blood. By the time the itching begins, 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.
