海豚是一种本领超群、聪明伶俐的海中哺乳动物。经过训练,能打乒乓球、跳火圈等。除人以外,海豚的大脑是动物中最发达的。人的大脑占本人体重的百分之二点一,海豚的大脑占它体重的百分之一点七。海豚的大脑由完全隔开的两部分组成,当其中一部分工作时,另一部分充分休息,因此,可终生不眠。

海豚是靠回声定位来判断目标的远近、方向、位置、形状、甚至物体的性质。有人做试验,把海豚的眼睛蒙上,把水搅浑,它们也能迅速、准确的追到扔给它的食物。 海豚不但有惊人的听觉,还有高超的游泳和异乎寻常的潜水本领。据有人测验,海豚的潜水记录是300米深,而人不穿潜水衣,只能下潜20米。至于它的游泳速度,

海豚更是人类比不上的。海豚的速度可达每小时40公里,相当于鱼雷快艇的中等速度。在鲸类王国里,要数海豚家族——海豚科的种类最多了,全世界已知共有30多种。有的种类虽名叫“鲸”,如虎鲸、伪虎鲸,其实也是海豚家族中的成员。

海豚救落水的人的故事,我们听了很多很多,海豚与人玩耍、嬉戏的报道也常有所闻,有的故事甚至成为轰动一时的新闻。经过学习训练的海豚,甚至能模仿某些人的话音。70年代,美国的三位科学家,让两头海豚学会了25个单词。新近,太平洋海洋基金会的欧文斯博士等4位科学家,对两头海豚进行训练,花了3年时间,教会它们700个英文词汇。不过有些科学家认为,不能把动物的“语言”或“方言”描绘得太离奇。

不过海豚确实具有与众不同的智力。它的大脑体积、质量也是动物界中数一数二的。目前,科学家对动物的智力有两种不同的见解:一种认为黑猩猩是一切动物中最进化、最能干的;另一种却认为海豚的智力和学习能力与猿差不多,甚至还要高一些。因而有人称海豚为“海中智臾”。 The dolphin is a skill outstanding, the smart sea mammals.

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.

英语作文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
