Dolphins are not fish. They are mammals. 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 man’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 man, and for thousands of years, there are many stories about dolphins and man. 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 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 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.

Do you and your classmates like Doraemon? Yes, it is a popular cat.

But you know, he is not a real cat but a robot（機(jī)器人）. The cat is a famous cartoon character（卡通人物）from Japan. Doraemon is from the 22nd century. I love Doraemon and I also love his 2,000 amazing gadgets（小玩意）!

Doraemon has a bamboo-copter（竹蜻蜓）. Put it on your head, and you can fly in the air. With a copter like this, I don’t need to go to school by bike any more. The bamboo-copter flies at 80 km per hour. It’s fast.

Here is the jelly translator（果凍翻譯器）. Eat this jelly and then you can speak and understand any language in the world. You can also understand what animals say.

Doraemon has a great door. It can take you to any place you want. First say the name of the place, and then pass through the door. You can get to that place in no time.

Doraemon also has memory（記憶）bread. Take a piece of the bread. Stick（粘貼）it onto a page of a book. Eat it, and you can remember everything on the page quickly. But I don’t like this kind of bread. Learning new things is fun, but eating it isn’t, right?

How I wish I could have some of these gadgets!
