【题目】In 2004, three young men went to a dinner party in San Francisco. Afterwards they wanted to share a video from the party with their friends. They wanted to send it over the Internet. But at the time, the process of sharing videos that way was difficult. Using e-mail did not work and the friends complained that there was no website to help them. So they created their own. They called their website YouTube. It made sharing videos easy, so the website soon became very popular. People watched 2,500 million videos in the first six months!

Today, more than 70,000 new videos go up on YouTube each day. People watch more than 1,000 million videos a day. Many last no more than 10 minutes. These videos show all kinds of things, from sleeping cats to earthquakes. Most of the filmmakers are not professionals(专业人士). They are just everyday people making videos, and they use the website in many interesting ways.

First, many people use YouTube to entertain others. One example is Judson Laipply. He made a funny dance video and put it on YouTube in 2006. People watched the video more than 10 million times in the first two weeks. Now people stop Judson on the street to ask, "Are you the dance guy on YouTube?" Some people have invited him to dance at their parties. A few women even asked to marry him. Judson wants to make more dance videos, and people look forward to seeing them.

Other people use YouTube to advertise a business. David Taub does this. He is a guitar teacher and he sells videos of guitar lessons on his own website. He wanted to increase his business, so he put short videos with free lessons on YouTube. People enjoyed watching the lessons on YouTube, and afterwards, many decided to go to David’s own website. Now David sells hundreds of guitar lesson videos each week.

People also use YouTube to help others. Ryan Fitzgerald is one example. Ryan is friendly young man who knows that some people are lonely and have no one to talk to. One day, he made a video of himself for YouTube. In the video, he gave his phone number and invited people to call him. In a week, he had more than 5,000 calls and messages from all over the world. These days, he is very busy talking on the phone. He helps people, but mostly, he just listens, like a friend.

Finally, some filmmakers use YouTube in a more serious way. They want to tell people about important events happening in the world. For example, they show clips(片段) of videos from countries at war, or they show people in need of help after a storm. Sometimes TV news shows do not give enough information about these events. Thanks to YouTube filmmakers, people can go to their computers and learn more.

For many people, YouTube is more than just another website to visit. It is a way to communicate with others. More and more people are using it every day, and they will probably find even more ways to use it.
