Your computer has been playing music for years, one CD at a time. Now hundreds of songs can be stored in your PC if they' re in the MP3 format (格式).
What is it? MP3 compressed(压缩) music into small computer files. You may download MP3 music several ways: Music can be downloaded from websites that have turned wide music libraries into MP3. Once MP3 music is on your PC’s hard drive, you can play it through your computer's speakers, "burn" it onto blank CDs or swap(交换) MP3 files with friends using e -mail. |
How much? Software needed to play and convert MP3 music is often free. Compact portable MP3 players start at around $ 40 and can hold hundreds of songs. A blank CD on which you can record music costs about a dollar. |
Advantages MP3 turns your home PC into a jukebox(自动唱机) . Small MP3 players are the size of a deck of cards(一副牌), making it easy to take hundreds of songs with you. Disadvantages You may find that some websites only allow you to listen but you can't download music. Others let you download music but can't be copied to MP3 players. And a growing number of new CDs make it impossible to copy songs to a computer. |

Many companies use guards and expensive alarm systems to protect their property(财产)。 Soon a new kind of protection will be used- robots. Engineers have been working on the first mobile robots for businesses. The robots will patrol(巡逻) factories, warehoues(仓库),and museums at night.
The mobile robots will move around slowly on wheels. They will be able to detect people through walls and pick up sounds, such as breaking glass. They can be fixed with lound sirens(警笛) to frighten thieves, or radios to signal police or guards.
To protect a building, a robot will have to move around without knocking into the walls. Information about the building will have to be stored in the robot’s small, built-in computer. A floor map could be programmed into the computer’s memory, for example.
A mobile robot will not be able to do everything. Unlike human guards, it will not be able to climb stairs, open doors, or move along rough ground. It won’t be able to tell the difference between friends and enemies. Because of that, people will have to be barred from the area it patrols.
One kind of mobile robot will be able to “sense” whether a chair or box has been moved and go around it. This robot will also judge size well enough so that it won’t send an alam if a cat crosses the room. And if someone tries to steal this robot, it will sound a loud, painful siren. The three-foot-tall robot will be hard to steal anyway. It will weigh about 200 pounds.
U.S companies pay almost $10 billion a year to protect their property with alarm systems and human guards. Mobile robots may be cheaper.
