The rockets take astronauts and man-made satellites into space. The satellites are used for communication, weather monitoring and research. But how do satellites stay up without falling down?
There are two opposite forces (力量) acting on the satellite. One of them is the force of gravitation (地心引力), which tries to pull the satellite towards the earth. The other force is created by the rotation (旋转) of the satellite around the earth. This force tries to take the satellite away from the earth. With these two forces, the satellite goes round and round. The gravitational pull of the earth (the force which pulls everything towards the ground) is like a rope which keeps the satellite from flying away.
Everything that goes up has to come down. It is only a matter of time before a satellite comes back to the earth. As time goes by, the satellite loses its speed, which makes the gravitational pull stronger than the force pulling it away. This makes the satellite crash (坠落) down to the earth. Which of the following uses of satellites is NOT mentioned?
| A．communication |
| B．monitoring the weather condition |
| C．doing some research |
| D．taking pictures |
The force that pulls the satellite towards the earth is created by ________.
| A．the earth |
| B．the satellite itself |
| C．the rotation of the satellite |
| D．the rope |
Why can’t the satellites fly away?
| A．Because of the force from the earth. |
| B．Because the satellite is too big. |
| C．Because of the force created by the rotation of the satellite around the earth. |
| D．Because people on earth have made ropes to tie the satellites tightly. |
The satellite will finally crashes down to the earth ________.
| A．when it flies faster |
| B．when its speed slows down |
| C．when people cut the rope |
| D．when there is no electricity in it |
Which of the following is TRUE according to the passage?
| A．There are four forces acting on the satellite. |
| B．The force of gravitation makes the satellite go round and round. |
| C．As time goes by, the satellite will finally fall down. |
| D．The satellite will stay in space forever. |
Have you ever seen snow? Many people in the world have not. Some countries never have snow; some have only a little on the tops of very high mountains. In the north of England, there is quite a lot of snow every winter, but in the south of England, there is usually little.
When a student from a warm country comes to England in autumn for the first time, he feels cold at first. There are often dark clouds, grey sky and cold rain in England in autumn, and most students from warm countries do not like this.
But snow is different. Though it is cold, it is also beautiful. Perhaps, after several dark mornings, the student wakes up one day, and there is a lot of light in his room. He thinks “Is it so late?” and jumps out of bed. But no, it is not very late. He looks out of the window and there is the snow on the ground and on the houses and everywhere. The light of his room comes from clean, beautiful snow.In which part of England is there much snow in winter?

I was born in the Tronto, Canada. Life looked bright and was filled with hope for my parents and me. My father and mother were married in 1980, and I was born next year.
As I grew into a man, I often looked to my father for advice and support. There were many things about his character that I admired, but like any young boy, I often thought that my father’s ideas were from the past and out of date.
I did well as a student and was the first person in my family to graduate from university. I went on to be a university professor and writer, and most people would say that I have had a very successful life. But I know much of my success is because of the lessons that he passed onto me.

Can plant eat people? Probably not. But there are many plants that eat meat. Some of them are big, and they can eat small animals. One famous meat- eating plant is the Venus flytrap(捕蝇草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of the book.. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly(苍蝇) touches one of the hairs, the leaf closes very quickly. Then the fly can’t go out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly. Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all the important things, especially nitrogen(氮). Animal meat has a lot of nitrogen. So some plants eat meat to get what they need. Let’s hope that some of the bigger plants don’t get the same idea.
根据短文内容判断。
1. The Venus flytrap grows in wet parts of the United States.
2. The Venus flytrap is a kind of plant.
3. The underlined word “presses” probably means（挤、压） in Chinese.
4. In the world, many animals eat plants but plants never eat animals.
5. From the passage, we know that not only animals eat plants, but also some plants eat animals.
