    Many people say dolphins are very intelligent(聪颖的). They seem to be able to think, understand, and learn things quickly. But are they c{#blank#}1{#/blank#} like humans or more like cats or dogs?

    Like humans, every dolphin has a "name". I{#blank#}3{#/blank#} is a special whistle(哨声). Scientists think dolphins, like people," t{#blank#}4{#/blank#}"to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans, dolphins use system (系统)of sounds and body language to c{#blank#}5{#/blank#}. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn.

When we are with our friends, we can t{#blank#}4{#/blank#} about everything with them. In large families, it's quite often for brothers and sisters to fight each other and then they can only go to their friends for some advice.

    It's important for us to have one g{#blank#}5{#/blank#} friend or a group of good friends. Even when they are not with us, we can also talk with them over the phone. We should talk with our friends often. It's good for our growth. Of course, we can feel that w{#blank#}6{#/blank#} we grow up.

    Do you have a good friend? H{#blank#}7{#/blank#} do you make friends, by writing letters or e-mailing? If you don't have one, you'd better find one so that you can help each other.
