“How are you?” is a nice question. It’s a friendly way that people in the U.S.A greet each other. But “How are you?” is also a very unusual question. It’s a question that often doesn’t need an answer. The person who asks“ How are you?” hopes to hear the answer “Fine”, even if the person’s friend isn’t fine. The reason is that “How are you?” isn’t really a question and “Fine” isn’t really an answer. They are simply other ways of saying “Hello” or “Hi”.
Sometimes, people also don’t say exactly what they mean. For example, when someone Asks “Do you agree?”, the other person might think, “No, I disagree. I think you’re Wrong...”But it isn’t very polite to disagree so strongly, so the other person might say “I’m not sure.” It’s a nicer way to say that you don’t agree with someone.
People also don’t say exactly what they are thinking when they finish talking with other people. For example, many talks over the phone finish when one person say “I’ve to go now.” Often, the person who wants to hang up gives an excuse: “Someone’s at the door.”“Something is burning on the stove.” The excuses might be real, or not. Perhaps the person who wants to hang up simply doesn’t want to talk any more, but it isn’t polite to say that. The excuse is more polite, and it doesn’t hurt the other person.
Whether they are greeting each other, talking about an idea, or finishing a talk, people don’t say exactly that they are thinking. It’s an important way that people try to be nice to each other, and it’s part of the game of language.
【小题1】“How are you?” is another way of saying "Hello." or" Hi."
【小题2】It is polite to say" No. I disagree I think you are wrong, "if you don’t agree with others.
【小题3】When someone says "I have to go now "On the phone.it means he wants to go on talking.
【小题4】"Someone is at the door." may be an excuse for finishing a phone.
【小题5】Sometimes people don't say exactly what they are thinking about just because they try to be nice to each other.

Recent research from the Pew Internet Project suggests that 90% of Americans aged from 12 to 17 use the Internet, and 51% of those teens use social networks. However, there are many possibleproblems with social networking sites and the teenagers who use them.

Apart from the social advantages, social networking sites can be used to record school research, develop artistic talents and experiment with other forms of subject creation. They provide a way to communicatewith others who share the same interests and to get helpful advice on ongoing projects.
Along with these advantages come some dangers. For example, most social networking sites are open to all, especially MySpace, which is the most popular social network among teens in America. It means that they could be put in unpleasant and frightening situations.
A greater danger is that teens may become objects of the people with secret purposes. The secrecy of some social networking sites makes it easy for dangerous people to find young teens and invite them into dangerous conversations. It’s easy for them to pretend as teens and draw children into dangerous real-world communication as well. Then further hurt might be on its way.
Another danger is identity stealing, which can happen when teens share too much information about their names, dates of birth and locations.
Therefore, it’s very important to make sure teens are safe when they use social networks.
Many of the same rules that work for online chat work for these sites:
※Don’t use your real name.
※ Don’t give out personal information to people you don’t know. A last name and a town
are enough for a bad guy to find where you are.
※ Don’t believe that people are who they say to be.
※ Immediately end any communication that makes you uncomfortable and report it to a
parent.
Only if you are sure of your safety, can you enjoy the fun brought by social networking. Besides, trying to deal with all problems on your own can lead to terrible results. Remember, asking your parents or school officials for help doesn’t mean you are unable to do anything but wiser than many others.
