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, dolphins 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.

Hotlines have become common in China. Some radio broadcasting stations use hotlines to encourage the listeners to take part in the talk shows  That’s a good idea. Yet, the fact is, some people do nothing but break the whole program.

Some people know little about the topic under discussion. Sometimes they do not even know what the host is talking about. So the host has to tell the caller what the show is about. Usually the caller will ask a few questions which express his hope and show his ignorance (无知). Then the host has to answer and explain—how silly this is! It wastes a lot of time.

It seems that some people phone the hotlines for fun. They just want to let the listeners hear them. They don’t care what the topic is, whether they themselves are interested or how silly they appear to be.x k b 1 . c o m

I’m totally bored by those people. It’s necessary for radio stations to improve the hotline programmers. In my opinion, if a caller does not know what is going on, the operator should not let the caller take part in it.
