The expression "Excuse me" is1 used in the United States than in China. 2 American says "Excuse me" when he wants to pass 3 someone, or leave a party or a dinner, or when' he finds himself late 4 an appointment(约会).

    "Thank you" means that appreciate (感谢) 5 someone has done for you. An American, says "Thank you" all day long. For example, he 6 the sales woman after she has served(服务)him. He will say "Thank you" to the cashier(收款员)when he 7 his food. He will Say "Thank you" to a student if he has, just answered the question. At 8, the husband will thank his wife if she brings him a cup of tea. On the other hand, the wife thanks her husband for helping her 9 her housework. So the American People's idea of 3010 polite is quite different from ours.

    It's hard to make friends if you stay at home all the time, so get out of the house and do things that will put you in touch with(接触)other people. It's easier to make friends with them when you find you like the same things as other people.

Don't be afraid to show people what you're really good at. You can talk about the things you like and do best. People will be interested in you if they, hear something interesting about you.

    Look at people in your eyes when you talk to them. That way, they'll find it easier to talk to you, or people may think you're not interested in them and may stop being interested in you.

    Be a good listener. Let people talk about themselves before talking about "me, me, me” You can ask people lots of questions and show that you are interested in their answers.

    Try to make friends with the kind of people you really like, respect(尊敬)and admire(羡慕). You shouldn't just make friends with those people you will meet them easily. Try to be friendly with all kinds of people. That way, you'll have a bigger group of people to choose from. Then you'll be easier to make friends with other people.

Recently, researchers have found that dolphins know their own names much like people. Dolphins talk to one another with whistles (口哨) and calls. Scientists have known that the animals also use unusual whistles to name each other. They had thought that dolphins only heard each other's voices. However, the scientists didn't know that dolphins listen for their names too.

To test this idea, the researchers caught 14 dolphins and recorded their name calls. The scientists then copied each dolphin's voice. When the changed recordings were played, the dolphins replied strongly to the names of their relatives and group members. They paid no attention to the names of dolphins they did not know.

Dolphins live in large groups that grow and change. Each dolphin's unusual whistle helps it quickly find a friend or a family member, or call for help. Understanding their calls requires learning. It's a skill that's seen in very few animals, which include humans and elephants.

Elephants, for example, communicate with sound. Their sounds can be heard by other elephants miles away. Dolphins, too, communicate with each other by making sounds like this. Elephants also communicate by moving their head, feet and trunk (象鼻). In much the same way, dolphins communicate by their movements. They often touch each other to express friendship.

Unlike dolphins, elephants also communicate by their great sense of smell. They can recognize other elephants by the smells they have.

Why do dolphins and elephants share the gift of communication? Scientists think it may be because they are social and smart animals. Both have strong family relationship. Now, whether they also have nicknames(绰号) is another question!
