Today,I want to talk about computer virus.One might think of a computer virus as a tiny computer program designed to perform mischief.Most computer users have heard about computer viruses.A computer virus is the result of a destructive program that someone has written and placed inside a computer program,which unsuspecting people then place in their computer system.
Some viruses can erase all the information from the place where it's stored on the computer's hard disk.But each virus is different.Some display strange messages on your computer screen; others make small changes in your computer programs.
Where do these viruses come from?They certainly don't float around in the air like some human viruses.Instead,like any other computer program,a human must create them.
Why do people create them?It's hard to say.Some people create these programs out of meanness to get even.While others create them just as a challenge.Why do you thing people create these very destructive programs?How does your computer get a virus?Almost exactly the way humans do.The computer gets exposed to one.Well,its not quiet that easy.
Many people get contaminated computer programs by trading programs with other people.Others get contaminated computer programs through the use of modems,which allow computers to communicate over telephone lines (ie.The Internet)
Most of the time,programs that arrive by modem or a trade are perfectly safe to use.However,you do stand a chance of getting a program that has been tampered with.Here a computer program virus is hiding inside the normal program.Many computer programs that are traded were copied illegally.
When this program enters your computer through your input device,it hides in your computer's memory and starts to duplicate itself like a disease.When you save your data,you also save the virus.Slowly but surely,the virus crowds out your data and causes major system problems.
The virus can't affect the computer's ROM (Read Only Memory),but it can affect RAM (Random Access Memory) and your computer disks.When your shut off your computer a virus that has been picked up will be lost,just like any other memory that is held in RAM.
If the virus is on your disk or hard drive,it will return to the computer when you use the program again.If you switch from one program to another without shutting down the machine,the virus will attach itself to the new program.In this way,it can slowly infect all your programs before you know that it exists.Today millions of dollars are being spent to rid and protect computer systems from these virus programs.
Commercial and shareware programs have been created with the sole purpose of detecting and fixing suspect programs that might be viruses infected.These detection programs should be ran when any disk is put into your disk drive or every time your computer is first started up each day to scan the computer's hard drive

I love English. English language is now used everywhere in the world. It has become the most common language on Internet and for international trade. Learning English makes me confident and brings me great pleasure.
When I was seven, my mother sent me to an English school. At there, I played games and sang English songs with other children . Then I discovered the beauty of the language, and began my colorful dream in the English world.
Everyday, I read English following the tapes. Sometimes, I watch English cartoons.
On the weekend, I often go to the English corner. By talking with different people there, I have made more and more friends as well as improved my oral English.
I hope I can travel around the world someday. I want to go to America to visit Washington Monument, because the president Washington is my idol. Of course, I want to go to London too, because England is where English language developed. If I can ride my bike in Cambridge university, I will be very happy.
I hope I can speak English with everyone in the world. I\'ll introduce China to them, such as the Great Wall, the Forbidden City and Anshan.
I know, Rome was not built in a day. I believe that after continuous hard study, one day I can speak English very well.
If you want to be loved, you should learn to love and be lovable. So I believe as I love English everyday , it will love me too.

Gong Xi Fa Cai!恭喜发财 - Happy Chinese New Year
新年好!---Happy Chinese New Year!
Hi, everybody, Chinese New Year is approaching and I would like to share something with you.
At 12:01am on February 18, 2007 the Chinese World will usher in the Year of The Pig
Chinese New Year is the most important holiday of the year just like Christmas to you. We settle all the debts we can. We buy oranges for good luck and kumquat金桔 trees to decorate our homes, and clean the house. There will be a family feast, and the older people will give little red packets of luck money (红包) to the youngsters. Usually there is a parade, including lion and dragon dances, stilt walkers, floats and acrobats. And there is noise: fireworks at midnight, gongs, drums and cymbals at the parade.
Doorways get a fresh coat of paint and the windows get decorated with paper cut outs.

Many families will play cards and board games on the evening of the February 1st while t waiting for midnight. Every light in the house is traditionally left on. Early the next morning, the red money packets are given out. Then people go door to door to wish their neighbors and relatives a prosperous new year.

Chinese New Year is a time for family members and the loved ones to get together. It’s a time for people who have been working hard all year round to take a little break. It is a time to receive as well as to give. It is a time to look back .It is also a time to look forward. Happiness, wealth, and long life are the primary themes.
Fifteen days later the lantern festival marks the end of the month-long New Year season.
I love the New Year. Happy Chinese New Year!
Thank you for listening. Good luck! And Bye!
