Dolphins are not fish. They are animals. They live in groups and speak to each other in their own language. But they are quite different from almost all land animals. Their brain is as big as men’s and they have a long life-at least 20 or 30 years.

Like some animals, dolphins use sounds to find their way around. They also use those sounds to talk to each other and to help them find food. They do not use their ears to receive sounds, but use the jaw-the lower part of the mouth.

It is strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand, there was a dolphin. The seamen liked him very much and gave him a very good name, Jack From 1871 to 1903, Jack met every boat in the area and showed it the way. In 1903 a passenger on a boat with the same of The Penguin shot and hurt Jack. Luckily the dolphin didn’t die, and after a long time he was well again. He guided the ships through the area for nine more years, but he refused to help the boat The Penguin.

Today, some people still kill dolphins, but many countries in the world now protect them. In these places, people are not allowed to kill them.

3.Who was Jack?

4.The dolphin guided the ships for about________.

5.According to the passage, which of the following is NOT right?

Dolphins (海豚) are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. Their brain is nearly the same size as our own, and they live a long time - at least twenty or thirty years.

Like some animals, dolpins use sound to help them find their way around. They also make these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw.

Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people.

There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903 Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area－except for The Penguin.

Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.

　　Dolphins (海豚) are very clever animals. They are usually not more than 3.3 metres long. They are found in many parts of the world. Dolphins like living together. Sometimes people can see groups of them swimming and playing in the water. It is impossible to tell how many there are around one ship, but there may be thousands. Dolphins live on fish but they do not spend all their time looking for them. They can spend more than six minutes below the surface (表面) of the water without coming up for air. Scientists say that dolphins are very much like humans. So it might be possible to teach them to talk. Some of the habits of dolphins are not the same as those of men, though it is certain that dolphins enjoy being with humans. Perhaps that is why they often go round after ships.
