A.day; night B. day; day C. night; day D. night; night Passage 8 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.

The Turning of the Earth

　　It seems to us that the earth stands quite still. But it is really moving all the time. It turns around a make-believe line through its centre. We call this make-believe line the earth's axis (地轴). The two ends of the earth's axis are called its poles. It makes the earth twenty-four hours travel around its axis once.

　　We look at the sun and say it “rises” and travels across the sky, but the sun doesn't really do so. It is the turning of the earth which makes us feel as if the sun were moving across the sky. We can't see that the earth is moving because everything else on the earth is turning with us. As the earth turns around every twenty-four hours, first one half faces the sun and then the other half. When our half of the earth is facing the sun, we say it is day. When our half is away from the sun, we say it is night.
