Imagine the situation. You are driving in a village or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car doesn’t work. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is used for finding your position(位置) with the help of satellites (卫星). A GPS can’t start your car, but at least you will know where you are.

? GPS, which means Global Positioning System(全球定位系统), is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find a GPS in cars, planes, or boats. Some of them have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.

? There are three parts to GPS. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites going around the Earth. The receiver communicates with at least four of the satellites and calculates its position. The third part of the system is a network of ground stations all over the world. They control (控制) the satellites and make sure they are working well.

? Some people think that in the future the GPS will be as common as the mobile. They are becoming better and cheaper. There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.

As young students, you have many dreams. These dreams can be very big, such as winning the Nobel Prize; they can also be small, such as becoming one of the best students in your class.

Once you find a dream, what do you do with it? Do you ever try to make your dream real?

Follow Your Heart by Andrew Matthews, an Australian writer, tells us that making our dreams real is life’s biggest challenge. You may think you’re not very good at some school subjects, or that it is impossible for you to become a writer. Those kinds of ideas stop you from realizing your dream, the books says.

In fact, everyone can realize his dream. The first thing you must do is to remember what your dream is. Don’t let it leave your heart. Keep telling yourself what you want every day and then your dream will come true faster. You should know that a big dream is, in fact, made up of many small dreams.

You must also never give up your dream. There will be difficulties on the road to your dreams. But the biggest difficulty comes from yourself. You need to decide what is the most important. Studying instead of watching TV will help you to get better exam results, while saving five yuan instead of buying an ice cream means you can buy a new book.

As you get closer to your dream, it may change a little. This is good as you have the chance to learn something more useful and find new hobbies.

American Classroom Rules

1. If the teacher asks a question, you should give an answer. If you do not understand the question, you should put up your hand and ask the teacher to repeat the question. If you don’t know the answer, it’s all right to tell the teacher that you don’t know. Then he or she knows what you need to learn.

2. There is no excuse for not doing your homework. If you can not go to school, you should call your teacher or your classmate and ask for the homework. It is your responsibility（责任）to find out what homework you have missed. It is not the teacher’s job to remind you of missed homework.

3. You must not be absent(缺席) on a test day. If you are badly ill, call and let the teacher know you will not be there for the test. If your teacher allows you to take a makeup, you should take the test within one or two days after you return to class. Bad illness is the only reason for missing a test.

4. Be on time! It’s not polite to be late. Also, it bothers other students. If you must come in late, be sure to do it quietly. Have your books out of your bag before you come into the classroom.
