C It is usually safe for humans to have contact with dolphins that live in an aquarium( 族馆；鱼缸).You may have seen pictures of marine biologists(海洋生物学家)swimming with dolphins there.These animals are playful and very gentle. Dolphins that live in aquariums can learn to do all kinds of tricks to make people happy. They can also help scientists learn more about their daily activities. Scientists already learn a lot about the ways dolphins communicate (with their babies and other dolphins by watching what they do in aquariums.They can see the dolphins when they eat,sleep and play.They can see when dolphins are healthy and when they are sick. By listening to the sounds dolphins make,and by watching them jump as high as sixteen feet in the air,scientists are able to learn more about the ways they communicate and play with each other.Their sounds and behaviours(行为)send signals(信号)to other dolphins about food and fun. In the past,scientists thought that they could learn to speak dolphin language and that dolphins could learn to know the sounds that humans make.However,this doesn't work. Dolphins can learn to respond (to humans,but not to their words.Scientists and "teachers"are now able to teach dolphins to do all kinds of things by giving them fish as a treat when they do tricks.
