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.

阅读下列短文,根据短文信息完成文后表格,每空一词。

Making a public speech is the thing that most people don’t want to do. The reason is that we are all afraid of making mistakes in front of others. The more important the speech is the more frightened we will be. But forget it now. Public speaking is easy. It’s just a simple talking Although I’m a shy man I’ve been making speeches and talking on radio and television for more than 30 years. Anybody who can talk can speak in public. Here are some of the lessons I have learned

Keep your speech simple. Your audience can’t take all of your main ideas and they can only remember one or two of them not ten or twenty. So you should prepare one or two of your main ideas very well. But if you can’t express what you want to say then your speech will not be paid attention to. And if you don’t have a clear idea of what you want to say your audience won’t either.

Organize your speech well. No matter how long or short your speech is you have to organize your speech—how you are going to open or begin what main points you want to make and how you’re going to close or end. A strong close is usually very important and critical(关键的) the last thing you say is what your audience will most likely remember. If not they will be confused.

Keep your speech not long. The standard length of a speech is usually 12 minutes. Most people can’t put their minds in one thing for too long time which will make them tired and lose their interest. If you pay no attention to your audience’s reaction(反应)the audience will get bored. Of course your speech will fail.

Following these suggestions above you can make a good speech in public and you will be an excellent speaker I think.
