　　Dolphins are not fish, but warm-blooded mammals (哺乳动物). The young dolphin is born in water and is 1 on milk from the mother's body. It can grow up to three metres in 2 . It has 3 and it eats fish. Its nose is very long, thus 4 a beak (鹰钩). It has a brain of the same 5 as a human being's.

　　Dolphins swim about in 6 , going over and under the 7 of the water in curves (曲身鱼跃). They make 8 to talk to each other and to help them find food and the 9 . They do not use their ears to 10 these, sounds, but the lower 11 of the mouths.

　　Some dolphins seem to look 12 people. They leave the others and swim up and down near the 13 , mixing with swimmers. Sometimes children may 14 on their back.

　　A story was told about a dolphin in the last century. In a dangerous part of the sea 15 the coast of New Zealand, the 16 learnt to look for a dolphin called Jack. Jack met every ship in the area and 17 it the way. Then a passenger on a ship called “The Penguin” shot and 18 him. Jack 19 and for nine years more continued to 20 all the ships through the sea except “The Penguin”, which later hit a rock and sank with a loss of a hundred lives.
