Thanks to the Internet, a whole new online world has been opened up for us to meet, chat and go where we've never been before. But just as in face to face communication, there are some rules of behavior that should be followed when on line.  The basic rule is simple: treat others in the same way you would want to be treated.   Imagine how you'd feel if you were in the other person's shoes. For anything you're about to send: ask yourself, "Would I say this to the person's face?" if the answer is no, rewrite and reread.  Repeat the process till you feel sure that you'd feel comfortable saying words to a person's  face. If someone in the chat room is rude to you, your instinct   is to fire back in the same manner. But try not to do so.  Just pay no attention to it, or block his message.  If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room. Everyone was new to the network once.  Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you license to correct everyone else. If you do decide to tell someone about a mistake, point it out politely At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended. It is not polite to ask others personal questions such as their age, sex and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions. The passage mainly tells us   _  . A) rules of the chat room B) some rules of Internet communication C) ways of sending messages D) ways of making online friends

Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish.
