C
Dolphins are not fish. They are mammals(哺乳动物). 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 live a long life—at least 20 or 30 years.
Like some animals, dolphins use sounds to help them find their way around. They also use these 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 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(乘客)on a boat with the name of The Penguin shot and hurt Jack. Luckily the dolphin didn't die, and after a long time he was well again. He guided(带领)the ships through the area for nine more years, but he refused(拒绝)to help the boat The Penguin.
All in all, dolphins are magic animals. 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.

Dogs can be our best friends, but we must understand their signs(示意)to stay safe!
Never go up to a barking(犬吠)dog, even if you think it is a happy bark. Wait for the dog to be calm(平静的)before you pet it.
Never take a toy off your dog. It may try to take the toy back and bite you by mistake!

If a dog seems scared, it might bite. So, stay away from a dog who is hiding, growling(低吼)and running away from you, or one who is barking, shaking and holding its tail between its legs. These are signs of fear. You should leave the dog alone and don't look it in the eyes.
