珍惜海豚的英语作文【一】
海豚是体型较小的鲸类，共有近62种，分布于世界各大洋，主要以小鱼、乌贼、虾、蟹为食。海豚是一种本领超群、聪明伶俐的海中哺乳动物。
海豚似乎永远不眠不休地四处游动。海豚是哺乳类动物，原先栖息陆地，后来又回到水中生活，用肺呼吸。若它们在水中持续睡觉，海豚将因无法呼吸而死。难道它们真的不用睡觉?若会睡觉，它们是睡在陆地，还是睡在海中呢?
其实若我们能够细心观察海豚一段时间，便会发现它们在游泳时，有时会闭上其中的一只眼睛。经调查它们的脑电波得知，它们某一边的脑部会呈睡眠状态。即使，它们虽然持续游泳，但左右两边的脑部却在轮流休息。若我们能够像海豚一样，一边睡觉一边工作，左右脑互相交替休息，一心便可以二用，搭车时睡觉便不怕坐过站了。
海豚的睡觉方式真奇怪呀!

珍惜海豚的英语作文【四】
每年夏天，我都会去青岛旅游，因为“极地海洋世界”里的海豚是我最喜欢的海洋动物之一，它就像我的朋友一样，每年我都会去看它。
伴随着动听的音乐，我又一次走进海豚表演馆。只见五只可爱的'海豚跟随着它们的训养师出场了。它们穿着亮灰色的外衣，雪白的衬衫，嘴巴扁扁的、短短的，尾巴像大型的蝴蝶翅膀，两只鳍来回扇动，还不时有节奏地唱着悦耳的“歌声”，好像在欢迎我们的到来。
海豚是人类的朋友，它能跟我们和睦相处。你看它一会儿和训养员转着圈儿的跳舞，一会儿和观众比赛转呼拉圈，转得比我们还好呢!
海豚顶球最有意思，它们在水里游着，忽然跳出水面，用尾巴轻轻碰了一下吊在空中的球，立刻球就晃动起来。
别看海豚身体沉重，但跳起来却很灵巧，它们突然从水面跃起，又很快地落下，观众们赞不绝口。
最后，一只海豚凌空飞起，拉了一下一个红球上的绳子，红球便马上打开了，还垂下一条红布，上面写着“山东青岛极地，快乐就在眼前。”
当我看见训养员温柔地抚摸它们的头时，我也好想摸摸它们啊!是呀，可爱的海豚为了让人们笑一笑，付出了多大的努力啊!为了让人们开心，它们刻苦训练，回不了大海，多可怜啊!我好想把它们放回大海，让它们自由、快乐。
看着可爱的海豚，我的眼前仿佛出现了一幅美丽的画面：海豚不再是逗人开心的工具，而是回到了自己的家园，我站在海边，轻轻地呼喊着海豚，它慢慢地向我靠近，带着我在大海里自由自在地游泳，陪我在海里嬉戏、玩耍……
