单选题A mother dolphin (海豚) chats with her baby over the telephone! They were in separate tanks connected by a special underwater audio link. "It seemed clear that they knew who they were talking with," says Don White, whose Project Delphis ran the experiment. But what were they saying? Scientists think dolphins "talk" about everything from basic facts like their age to their emotional state. "I speculate that they say things like "there are some good fish over here," or "watch out for that shark because he"s hunting,"" says Denis Herzing, who studies dolphins in the Bahamas. Deciphering (译解) "dolphin speak" is also tricky because their language is so dependent on what they"re doing, whether they"re playing, fighting, or going after tasty fish. During fights, for example, dolphins clap (碰撞) their jaws to say "Back off!" But their jaws clap while playing, too, as if to show who"s king of the underwater playground.

单选题{{B}}Passage One{{/B}} Communication is the sending of information or news from one person to another. If human beings could not communicate with one another, each person would have to learn everything for himself. Although animals as well as men can communicate, so far as we know, they can express only the simple emotions like pain, joy, fear, hunger, anger and love. Some animals have a more advanced form of language using sounds, and others use a wide range of sounds and face movements, but we still have much to learn about these animal languages. Speech is the most important means of communication between people. But it is not the only one. Nor is it the oldest. We use facial expressions, gestures and hand movements to express our feelings and to send signals to other people. Animals use this "body language" a great deal. The sign language used by deaf people is an example of communication without speech,while blind people communicate largely through touch and hearing.
