Q: In 2004, three young men went to a dinner party in San Francisco. Afterward ,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. 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 afterward, 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 less than 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 when he can, but mostly, he just listens, like a friend. Finally, some filmmakers use YouTube in a more serious way. They want to inform people about important events happening in the world. For example, they show clips 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.

Q: For more than 40 years, scientists have sought to learn how well human beings can adapt to long periods in space. The International Space Station continues to provide valuable knowledge about spaceflight. But an earlier space station, Skylab, helped make the current space project possible.

Canadian astronaut Chris Hadfield sang aboard the International Space Station on May 12, 2013. His music video has become extremely popular. The astronaut played his own version of David Bowie's song Space Oddity. He performed while floating weightlessly, with images of planet earth and space appearing in the window behind him.

Chris Hadfield recently returned home after nearly five months on the space station. For him, the long flight produced a hit video on YouTube and no major physical problems. But 40 years ago, scientists did not know how humans would react to long-term spaceflight. To find out, NASA, the American space agency, launched Skylab in May, 1973. Over nearly a year, three teams of astronauts visited Skylab for stays of between 28 to 84 days. They learned how people react to extended periods in space.

Gerald Carr commanded Skylab 4. He spoke at a NASA event marking the 40th anniversary of Skylab's launch. He said that the loss of the body's muscle mass was a main concern. Astronauts on Skylab used exercise equipment to stay strong. The astronauts spent their workdays carrying out experiments, including biomedical research.

Marshall Porterfield is the director of NASA's Space Life and Physical Sciences Division. He says the Skylab astronauts' understanding of their own ability to deal with long-term spaceflight continues to help current astronauts. NASA says the next step for life away from Earth is a year-long space station mission, set for 2015.

Q: CHAPTER III.

TWO QUARRELS.

Three days later the shooting party assembled. Several gentlemen came to stay at the house, while Ronald Mervyn and his party, of course, put up at Mervyn Hall. The shooting was very successful, and the party were well pleased with their visit. Reginald Carne was quiet and courteous to his guests, generally accompanying them through the day, though he did not himself carry a gun. After the first day's shooting there was a dinner party at Mervyn Hall, and the following evening there was one at The Hold.

Lieutenant Gulston enjoyed himself more than any one else, though he was one of the least successful of the sportsmen, missing easy shots in a most unaccountable manner, and seeming to take but moderate interest in the shooting. He had, very shortly after arriving at the house, come to the conclusion that the doctor was altogether mistaken, and that Reginald Carne showed no signs whatever of being in any way different from other men. "The doctor is so accustomed to us sailors," he said to himself, "that if a man is quiet and studious he begins to fancy directly there must be something queer about him. That is always the way with doctors who make madness a special study. They suspect every one they come across of being out of their mind. I shouldn't be at all surprised if he doesn't fancy I am cracked myself. The idea is perfectly absurd. I watched Carne closely at dinner, and no one could have been more pleasant and gentlemanly than he was. I expect Mackenzie must have heard a word let drop about this old story, and of course if he did he would set down Carne at once as being insane. Well, thank goodness, that's off my mind; it's been worrying me horribly for the last few days. I have been a fool to trouble myself so about Mackenzie's croakings, but now I will not think anything more about it."
