In the near future, people in some parts of the world will watch a new kind of television. It is called the high definition television(高清晰度電視機(jī)) or the HD-TV. The main difference between an HD-TV and a normal television is the picture. It is more clear and detailed. This is because the HD-TV has many more points and lines that make a television image.
Every color television picture contains thousands of red, green and blue points. They all come together as an image in the eye of the person watching. The points are organized in lines that go across the television screen. There are more than five hundred lines in a normal television. The HD-TV has two times as many. To get this clear picture, you must have a big screen. Experts say people using a small screen will see little difference.
The HD-TV also has clear sound. It is like the sound on a CD. All these improvements make an HD-TV very costly. A major problem with the HD-TV is its broadcast signal(傳播信號(hào)).The signal is bigger than normal because it carries more electronic information.

According to a new Ministry of Education survey, students’ safety has become a big problem. Nearly 50 percent of students say they are worried about robbery(搶劫) on the way to and from school. Now in many big cities in China, some schools have taught an unusual lesson: self-protection(自我保護(hù)) . Students like this lesson as there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.
Chen Haoyu, a teacher at Beijing No.25 Middle School and a self-protection expert(專(zhuān)家),gives young students advice on how to deal with danger.
If you are robbed(搶劫), keep calm. If you can’t cry for help or run away, give the robber your money. Try to remember what the robber looks like and tell the police.
If you are in a traffic accident and a car hurts you, you should take down the car number. If it is a bicycle, try to contact your parents before you let the rider go. This is because you don’t know how seriously you are hurt.
If it is raining hard and there is lightning(閃電), don’t stay in high places and keep away from trees.
When there is a fire, get away as fast as you can. Put wet things on your body and try to find an exit(出口). Do not take the lift!
If someone is drowning(溺水) but you can’t swim, don’t get into the water. Cry out for help.
Remember that danger is never as far away as you think. Take care of yourself at all times!
