小鱼儿自述
Hi！我是一条生活在小河里的小鱼儿，我叫清清，是家族里最小的鱼儿。我们家族里除了我这样的小鱼和一些充满智慧的老者，还有一些身手机灵敏捷的青年人，其他的都跑的跑了，病的病了，死的死了。你想知道是怎么回事吗？那就听我慢慢道来。
以前我们生活在一条清澈见底的小河里，小河底下有各种各样的、形态不一的鹅卵石，有碧绿的、随水浮动的水草。我们经常在水草中捉迷藏。小河上还有小船，我们等小船滑过来，然后一群鱼儿就七手八脚地咬住船桨，等人们回过神来，我们早已消失得无影无踪了。
可现在，人们不保护环境，经常把垃圾往我们住的地方乱丢。我爸爸妈妈就是因为吃了塑料袋死去的。爷爷和奶奶则是被一袋结块了的水泥砸死的。那时我们正在散步，没想到半路上砸下了一袋重重的水泥，躲都来不及躲，奶奶为保护我而当场被击中头部而死。爷爷想去救奶奶，结果吸入了量的水泥，到现在落下了严重的膘病。前几天我在动物新闻里看到这样一则新闻：昨天在小河森林里，一只小鹿在捕食的时候见到一只白色的餐合，吃了里面的剩菜，结果中毒药了。虽然立刻送到了动物医院急救，但因中毒太深，经抢救无效死亡。这都是人类无视环境造成的恶果。
人类除了乱扔垃圾还滥伐森林。昨天我的好朋友小鸟和和跑来对我说：“清清，我们的家被人类砍掉了，爸爸妈妈也不知去向了。我要去找爸爸妈妈去了，找不到爸爸妈妈的话，我得去找一个新地方安家了。再见！”
人类呀，请你醒醒：你们的动物朋友变得越来越少了；我们家族成员的不断减少你们人类就是罪魁祸首。我们鱼儿代表动物界向你们人类呼吁：为了世界和平，请你们保护环境，给我们一片生存之地！

　我是一条活泼机灵的小鱼。以前，我和金金、咪咪、龟龟还有螃螃一起生活在清澈见底的小河里。小河旁边一年四季绿树成阴、鲜花盛开。水底长着一丛丛绿油油的水草和大小不一、五颜六色、奇形怪状的石头。清晨，小鸟清脆的叫声把我们从甜美的梦乡里唤醒。早晨，我和锻炼的人们一起扭扭腰。下午，我和伙伴们一起玩耍嬉戏。晚上，我们一起睡觉、听故事。我们生活得无优无虑，逍遥自在。

　　有一天，我和小伙伴们正在玩游泳比赛，一场突如其来的灾难来临了，有人往河里扔了许多包大垃圾。顿时，我们吓得目瞪口呆，惊慌失措。有的小鱼被活活砸死，有的小鱼一边逃还一边伤心地哭泣，还有的小鱼虽然逃走了，但不是丢了尾巴，就是丢了鱼鳍。垃圾迅速散开，有瓜子壳、臭鞋子、果皮、啤酒瓶、骨头……什么都有，把河水弄得浑浊不堪，还散发着一股恶臭。慢慢地，我的伙伴们都不幸遇难了。最可怜的要数才出生两个月的丽丽了，她的爸爸妈妈都被砸死了。

　　救救我们吧，人类，请不要乱扔垃圾了！

在一片清澈见底的小河里，有一条小鱼儿。它整天无忧无虑、自由自在。早晨，太阳冉冉升起，把河水照得波光粼粼，远看，像一面明亮的大镜子，映衬着蓝天、白云。小鱼儿早早地醒了，不一会儿，一只翩翩起舞的蝴蝶飞来了，冲着小鱼儿笑，原来，它是小鱼儿的好朋友，每天早晨都和小鱼儿一起嬉戏玩耍。到了中午，小鸟儿们也来与小鱼儿共度美好时光。下午，与小鱼儿戏闹的朋友更多了。晚上，花儿们又和它聊天。它就这样，每天都活得那么灿烂
!
可是，有一天，不幸降临到它头上了。河边忽然砌了一座工厂，一开始，小鱼儿没当回事，照样和它的小伙伴们一起玩耍，可过了几天，小鱼儿觉得身体难受了，玩的时候也没劲了，和它一起玩儿的小伙伴儿也越来越少了。原来，河边砌的这座工厂，每天都会排出许多污染环境的氧化物，使得小鱼儿身体难受极了。
一天一天地过去了，小鱼儿的身体每况愈下。它没有了小伙伴们的陪伴和安慰，感到孤单极了。原本清澈见底的河水成了浑浊不堪的脏水，河面上漂着各种各样的垃圾，散发出一阵阵臭味。
最终，这片河被人们填起来了，盖上了一座座新楼房。而此时，可怜的小鱼儿正一动不动地躺在离这儿不远的泥坑里。它睡着了，做了个美梦，梦见它又回到从前，和小伙伴们一起嬉戏玩耍、聊天，永远都那么幸福……
