How can you make a strong password? It should be eight characters or more, with a mix of letters, numbers and symbols. One way to create a long and easy-to-remember password is to separate short words with spaces or numbers. Having safe passwords is necessary for surfing the Internet safely. But it’s not the only thing you must do to keep safety online. Here are some other web safety tips:
●Never give out information that will allow someone to find you offline. That includes your full name, address and phone number.
●Don’t include your real name as part of your online screen name.
●Never meet people you met on the Internet in person. If you insist on breaking this rule, meet in a very public place and consider taking an adult with you.

Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. 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 a device(装置) which uses satellites (卫星) to find the user’s position(位置). It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are.
GPS, which means Global Positioning System, 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 GPS devices in cars, planes, or boats. Some of these devices 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 the Global Positioning System. 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 orbiting the Earth. The receiver contacts at least four of the satellites and calculates(计算) its position. The third part of the system is a network of ground stations. They are all over the world. They control 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 cheaper and more and more accurate(精确的). 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.

A programmer and an engineer are sitting next to each other on a long flight from Los Angeles to New York. Most passengers are sleeping or reading. Time goes so slowly.
The programmer leans over to the engineer and asks if he would like to play a fun game.
The engineer just wants to take a nap, so he politely declines and rolls over to the window to have a short rest.
The programmer persists and explains that the game is really easy and has a lot of fun. He explains, I ask you a question, and if you don’t know the answer, you pay me $5. Then you ask me a question, and if I don’t know the answer, I’ll pay you $5.
