There are about 76 different kinds of whales and dolphins around the world.Though they live in water，whales and dolphins are not f（1）ishish .They are warm-blooded mammals （哺乳動(dòng)物），like cats，dogs，and humans.Their babies are born alive and feed on mother's milk.

Bottlenose dolphins are probably the best known dolphins.They are the ones most often seen on TV and in ocean parks.They can be t（9）rainedrained to perform jumps，flips，and other exciting moves.During their training and while they are performing，the dolphins are usually given fish as a reward for c（10）arryingarrying out certain behaviours（行為）.However，since these are all natural behaviours to begin with，the question is，who's training whom？
