[Q]: Article: In the past, friendships were greatly limited by time, space and attention; increasing home and workplace mobility has made it even harder to keep social relations over time. Through a combination of user controls, new technologies and changing standards of social behavior, Facebook is freeing us from these limitations, making friendships more accessible, pleasant and diverse than ever before. First, Facebook allows you to find and rediscover friends and then reminds you of these connections, so that you are less likely to fall out of touch with the long-lost school friend, or the family member in a different country. 'Second, Facebook creates an environment that allows you to interact easily with others : you can share your photos,videos,links and thoughts with your friends, and respond to what they share in turn. Third, Facebook's unique technical system helps you to discover your friends,most valuable stories. These technologies allow people to keep and enrich friendships that they might otherwise have been unable to keep. The effect of this is very great. A recent study by Keith Hampton for the Pew Internet and American Life Project discovered that users of social networking websites have larger, more diverse social circles, online and offline. This outcome comes at no cost to one's closest relationships, which are kept in person and over the phone. Instead, the hour that the average user spends each day socializing on Facebook comes at the expense of less social activities, such as the three or so hours a day the average person spends watching television. Time may limit our ability to keep social ties, but our desire for social communication is limitless. Just as boats have allowed us to cross oceans and vehicles have allowed us to move mountains, Facebook is a tool that allows us to stay more deeply connected with a larger and more diverse set of friends.
Answer: Change the behavior towards your friends.

[Q]: Article: Did you know that there are actually people who have paid for a flight to the moon? In the future, there will be a lot more opportunities to travel to faraway places than now... perhaps even as far as the moon. As people adventure further and further away and as planes, trains, cars, and rocket ships become faster, is it safer to have these vehicles controlled by humans or by computers? While many flights by plane are controlled automatically by machines, most people today wouldn't let their car drive itself. That's because currently the autopilot function on your car can only keep it on the same course you are travelling on. It won't turn the car right or left. It won't stop if an animal jumps in the way. However, cars today can sense when something is too close and warn the driver with flashing lights and alarms. Many cars also have GPS(global positioning systems) that tell drivers which road to take and when to turn. These systems, unlike human drivers, never get lost. In the future, it is easy to believe that your car will be better able to drive itself with the aid of computers that can determine the position of your car and the speed it should travel at. In addition to computers being 'smarter' than people regarding the best way to go or knowing how close another vehicle is, computers don't get sick, tired, or angry. This means they won't make the same mistakes that people make when they are not having a good day. While responding with emotion is a good thing when choosing the best way to deal with a friend's personal problem, it may not be such a good thing when deciding what to do at the wheel of a fast-moving vehicle. So what are the disadvantages of autopilot systems? Maybe one disadvantage is that a small computer problem could cause a serious accident. It could also be argued that in unexpected situations, computers might not be able to respond appropriately; some decisions require human emotions. Another problem might be that if everything were controlled by computers or robots, people wouldn't have any jobs.
Answer: Technology of Future Travel
[A]: What is the best title for the passage?

[Q]: Article: It is a novel that is probably more talked about than read. People think: "It's such a big book! It has such a serious theme!" The feeling that they are going to be taught a long, hard lesson often puts readers off. But really, War and Peace (1869), which tells the stories of five upper-class families in Russia at the time of the 1812 French invasion, is not to be missed. Reading this novel is one of those once-in-a-lifetime experiences, like climbing the Great Wall: You will regret it if you do not try. Earlier this month, USA Today reported that a six-episode War and Peace miniseries produced by the BBC would air next year. With a complex plot and so many characters, readers unfamiliar with the work might be most interested in the characters from the financially-troubled Rostov family of Moscow. Count Rostov has four teenage children. Natasha is in love with Boris Drubetskoy, who is about to become an army officer. Nikolai Ilyich loves the poor Sonya, a ward of the family, but his family is not happy with their relationship. The proud Vera is about to start a happy marriage with a German-Russian officer. The youngest Rostov is the 9-year-old Petya, who, like his brother Nikolai, has his heart set on fighting for his country. The lives of all are about to be changed by the upcoming great war that involves many other major characters of War and Peace, such as Prince Andrei, who goes into a military career partly in order to get away from his unhappy marriage to the socialite Lise. The novel has a great reputation among many kinds of writers and millions of readers. US writer Ernest Hemingway wrote: "I don't know anybody who could write about war better than Tolstoy did." A comment by the great 20th-century Russian short-story writer Isaak Babel shows the rich sense of history that Tolstoy's work conveys. "If the world itself could write, it would write like Tolstoy," Babel commented.
