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.

Passage 9
We’ve talked about snails (蜗牛) and their slow move. But much of the time snails don’t move at all. They are in their shells (壳) —sleeping.
Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense (感觉) of smell is very strong. It helps the snail to find food and the new greens.
A snail’s mouth is no bigger than the point of a pin (大头针). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.

Passage 10
Jupiter’s Moons and How They Travel
The many moons of Jupiter travel around the planet in different directions (方向).
Jupiter is the largest planet in our solar system. Over the years, scientists have found that Jupiter has its own small solar system. Earth has one moon. Jupiter has at least sixteen and probably more.
Since there are so many moons, scientists began to number them. The numerals(numbers)tell the sequence, or order, in which the moons were found. They were slower to name the moons. All of Jupiter’s moons now have a name as well as a number.
The first five moons to be discovered are known as the “inner moons”. But they are not the closest to the planet. The closest is only 127,600 kilometers away from Jupiter. All the inner moons circle the planet in counter-clockwise direction, that is, opposite of the hands of a clock.
Jupiter’s middle group of moons are at least 11,100,000 kilometers from the planet. They also move in a counter-clockwise motion (moving). The four farthest moons are at least 20,700,000 kilometers away. These are called “outer moons”. They circle in a clockwise motion.
How many more moons do you think will be discovered？
1.What does “solar system” in this article mean？______
A. 银河系 B. 宇宙空间 C. 流星雨 D. 太阳系
2.Things that travel in the same direction as the hands of a clock are said to be traveling in a______.

Passage 11
WHY IS THE SUN IMPORTANT？
The sun is a huge, hot, bright star. It is important because without it there would be no life on Earth. The sun gives us light and heat.
All living things need light and heat from the sun to live. Plants need light and heat to grow. They use the light from the sun to make food. We cannot make our own food, but plants can. All the food we eat comes from plants in a food chain(链)which starts with the sun.
