Can you speak to dolphins? Of course you can but you won't be able to understand them! We interviewed a biologist and asked her what research on dolphin communication has shown. This is what she told us. Just like dogs, cats and other mammals, dolphins communicate by using sound, vision , touch and taste. Each dolphin has its own signature whistle to identify itself and to call others. Dolphins don't have the ability to smell, but their hearing and eyesight are excellent. We also asked Jane if dolphins have got their own language. She told us that they have and that dolphins started talking to each other from birth. They make different sounds, including whistles, squeaks and click. Sometimes they even sound like a heavy metal band! We then asked Jane if any interesting experiments have been done. She told us that a very interesting experiment had been done with a mother dolphin and her two-year-old baby in an aquarium. They talked to each other over the telephone! The two dolphins were in separate tanks which were connected by a special under water system. Unfortunately the biologists couldn't understand what the dolphins were talking about because they haven't been able to decode dolphin language yet. However, it was very clear that the dolphins knew what they were talking about. Finally we asked Jane if there was hope that we would be able to understand dolphins in the near future. She told us that she and her team have been listening to dolphins for more than 17 years, using special equipment to record and analyze their language. Unfortunately they haven't been able to decode it yet, but who knows -- maybe one day we'll get a phone call from a dolphin. The word "analyze" in the reading mean _ . A) use B) translate C) copy D) study
