In today's world, we rely on computers as never before. They are used for everything from ordering a pizza to running hospitals and military defense systems. Banking and credit card information is stored and accessed by computers. So what happens when a computer gets infected with a virus? One effect is that people's access to their e-mail accounts is cut off. A more serious possible consequence is that billions of dollars could be lost.
A virus is a computer program that copies itself onto other programs and infects them. Similar to an easily spread disease, a computer virus goes from computer to computer, either adding to or changing the tasks a program is designed to do.
The first computer viruses were created in the mid '80s and had varying effects. Some caused files to be deleted, or made the letters on the screen appear to fall off. Others displayed a specific message once the computer was turned on.
Viruses today are much more widespread and dangerous than ever before. Perhaps the most damaging to date has been the "I Love You" virus. "I Love You" appeared in May 2000 and has possibly been the most destructive virus in terms of monetary loss.
The virus is released when an attachment to a fake e-mail message is opened. By changing the names of files on computers, "I Love You" makes them difficult to access. It also searches for important personal information, including passwords, which it sends to a web site for others to see.
It is estimated that more than 45 million people in 20 countries have had their computers infected by the "I Love You" virus. Some say the cost of repair and lost business has been more than US$10 billion.
If you own a computer, it is important to keep it in good health by installing an anti-virus program. If updated frequently, it will protect your e-mail access--not to mention your wallet.

In 2003, Bethany Hamilton,13, lost her left arm to a shark attack while surfing off Kauai, Hawaii. A new film ,Soul Surfer, is based on the story of how she overcame that to achieve her dream of becoming a professional athlete.

Growing up on the “garden isle” of Kauai, Hamilton spent every minute she could riding the waves. She was on the verge of (即将) becoming a top competitor in professional surfing. But while she was practicing at an isolated cove (小湾)，a four-meter-long tiger shark ripped off her left arm. Though her life was saved, nobody could imagine she would ever get back on a surfboard again.

In a true test of her faith and by tremendous will power, Bethany did get back up on a surfboard only a month after the attack. Six months later, she was competing again. Bethany Hamilton won her first amateur surfing championship just two years after she lost her arm. She also established the “Friends of Bethany,” a non---profit foundation dedicated to supporting sharks attack victims.

It’s a story told in her autobiography, which is the basis for the film that stars teenager Anna Sophia Robb. “I knew Bethany’s story, of course, but I thought ‘What an incredible role’ ,”explains Robb. “I was so fascinated by all of the challenges. What would it be like to have your arm taken and what would go through your head and how would your faith be challenged?”

The filmmakers used special effects to digitally remove Robb’ s arm .However ,no tricks were necessary for the surfing scenes because Hamilton herself did the breathtaking wave riding.

Now 21, Hamilton says she hopes audiences find inspiration in the description of the sport she loves.

“Not a lot of people know that much about surfing, so I hope they’re educated about it,” Hamilton says. “And most of all if people are going through a hard time, they could be encouraged and find inspiration to push through those hard times and see that, in my case ,so much good has come out of it.”
