海豚是一種本領超群、聰明伶俐的海中哺乳動物。經過訓練,能打乒乓球、跳火圈等。除人以外,海豚的大腦是動物中最發達的。人的大腦占本人體重的百分之二點一,海豚的大腦占它體重的百分之一點七。海豚的大腦由完全隔開的兩部分組成,當其中一部分工作時,另一部分充分休息,因此,可終生不眠。

海豚是靠回聲定位來判斷目標的遠近、方向、位置、形狀、甚至物體的性質。有人做試驗,把海豚的眼睛蒙上,把水攪渾,它們也能迅速、準確的追到扔給它的食物。 海豚不但有驚人的聽覺,還有高超的游泳和異乎尋常的潛水本領。據有人測驗,海豚的潛水記錄是300米深,而人不穿潛水衣,只能下潛20米。至于它的游泳速度,

海豚更是人類比不上的。海豚的速度可達每小時40公里,相當于魚雷快艇的中等速度。在鯨類王國里,要數海豚家族——海豚科的種類最多了,全世界已知共有30多種。有的種類雖名叫“鯨”,如虎鯨、偽虎鯨,其實也是海豚家族中的成員。

海豚是一類智力發達、非常聰明的動物,它們既不像森林中膽小的動物那樣見人就逃,也不像深山老林中的猛獸那樣遇人就張牙舞爪,海豚總是表現出十分溫順可親的樣子與人接近,比起狗和馬來,它們對待人類有時甚至更為友好。

海豚救落水的人的故事,我們聽了很多很多,海豚與人玩耍、嬉戲的報道也常有所聞,有的故事甚至成為轟動一時的新聞。經過學習訓練的海豚,甚至能模仿某些人的話音。70年代,美國的三位科學家,讓兩頭海豚學會了25個單詞。新近,太平洋海洋基金會的歐文斯博士等4位科學家,對兩頭海豚進行訓練,花了3年時間,教會它們700個英文詞匯。不過有些科學家認為,不能把動物的“語言”或“方言”描繪得太離奇。

不過海豚確實具有與眾不同的智力。它的大腦體積、質量也是動物界中數一數二的。目前,科學家對動物的智力有兩種不同的見解:一種認為黑猩猩是一切動物中最進化、最能干的;另一種卻認為海豚的智力和學習能力與猿差不多,甚至還要高一些。因而有人稱海豚為“海中智臾”。 The dolphin is a skill outstanding, the smart sea mammals.

Recently, the Pacific Ocean foundation owens PHDS four scientists, training for two dolphins, spent three years, the church they 700 English vocabulary. But some scientists think, cannot animals "language" or "dialect" describe too extraordinary.

1. It was the first day of the June holidays. My friends and I decided to meet at the beach for a picnic. As my parents had to leave for work that day, they left my six-year-old sister in my care. When we reached the beach, the sun shone brilliantly and the water glittered invitingly. The coconut trees swayed to the gentle breeze in the warm sunshine.To my surprise, my friends were not at the beach yet. They were unlikely to arrive late. At about a hundred metres away, there was a large crowd. Some were shouting and some were waving frantically. I held my sister by her hands and walked towards the crowd.I gawked with disbelief. It was a dolphin; it was still struggling to return to the sea. I finally found my friends and they told me that they were swimming when a huge wave washed the dolphin onto the shore. Not long after, the Civil Defence Force cordoned off the area and tried to help the dolphin get back into the sea.Soon after, the media and the camera crew arrived. They interviewed the on-lookers and photographed the dolphin. Finally, the Civil Defece Force managed to get the dolphin back to the sea. Before it retured, the dolphin looked back and made a noise as if it was saying "Thank You" to everybody.It was indeed an eye and mind opening experience for my sister and me.

英語作文dolphin is helpful

Dolphin(海豚) is my favourite animal. It is one of the most precious animals. Their bodies are very long, about one zhang(丈). Dolphins live in the sea. They live on fish, shrimps and so on.Dolphins are very friendly and peaceful. They never attack people. Instead, they have saved many people in danger in the past years. How helpful the dolphins are! Dolphins are very clever. People often train them so that they can give a dolphin show which brings people a lot of happiness and joy. Unluckily, the number of dolphins is getting smaller and smaller. Because of water pollution, there is less and less space for dolphins. Many people make money by hunting dolphins. If we don't protect them, maybe we'll lose our good friends one day. As a student, I hope more and more people should take actions to protect dolphins
