一周以前的一个早上,我在店里看见老谢阿姨摆摊的那个地方有一个叔叔在卖可爱的小鱼,我连忙的拉着妈妈的手去看,哇塞!好多小鱼呀!我兴奋极了,我发现有热带鱼、金鱼……我特别想买,就恳求妈妈说:“妈妈给我买几条小鱼吧!求你了。”妈妈看了看,就买了中间鱼缸的小鱼,买了一条黑的、一条红白的还有一条金色的。另外买了一个鱼缸,一朵假花还有一包鱼食,鱼缸里有彩色的石子,五颜六色美丽极了。我非常喜欢这些可爱的小金鱼。

晚上,我要想办法把它们拿回家,不能放在鱼缸里,一刹车蹦蹬,不仅鱼掉了,鱼缸也会打碎,假花也会掉,鱼食也没用了,这钱不是把花了吗?一眨眼的功夫,我想出了一个绝妙的办法。我飞快地跑到老大伯伯家要了一个袋子,把小鱼倒进去(包括假花),然后让妈妈把鱼缸和鱼食拿上,这样鱼、假花、鱼缸、鱼食都不会浪费了。回到家我观察我的鱼,黑色的眼睛好大,小尾巴左摇右摆像一只小蝴蝶,红吧色的头好红啊!红的跟火花一样,我最喜欢的是金色的的那条金鱼,它的肚子比较大像吞了一颗珍珠,该起名字了,我看它们都有特点就按照他们的特点起名字吧!黑色的叫蝴蝶尾,红白色的叫红火花,金色的叫珍珠。

这些小鱼给我带来了很多乐趣,我呀,早晚要给它们喂食、换水,我每次把鱼缸端下楼时我都要小心翼翼,我怕把鱼缸打了鱼就死了,所以我很害怕。爸爸说;“只要你不听话某天早上就让我喝鱼汤。”我说:“坏爸爸坏爸爸”爸爸却不急不忙地说:“明天有鱼汤喝喽。”我说:“好呐,我听话让你没机会喝鱼汤。不过不能再我听话的时候喝鱼汤。哼!”每次我不听话他都会这样说可是不会这样做呵呵O(∩_∩)O人家心动不如行动,他呢?行动不如心动啊!我觉得我的小鱼永远不会死,是不幸的是,唉唉唉唉唉唉╮(╯▽╰)╭如果想知道的话就看下一个自然段吧!

前几天,我回到家突然发现,我的小珍珠死了我一下子愣住了我马上跑到小珍珠旁边,看看它是否真死了,我发现小珍珠反过来了,我揉了揉眼睛,啊!小珍珠真死了我哭都来不及我想:“小珍珠为什么会死呢?其他两条鱼却安然无恙?”我和妈妈把小珍珠扔进了大海。

我感觉我失去的不是一条小鱼,是一个心肝宝贝,因为我最喜欢它了!我很伤心很伤心,一直在哭,只要看见小鱼我就想起小珍珠,我真的有一种无法用语言表的的伤痛。我虽然很伤心但是我要养好其他两条小鱼,我不会让它们死的,我会努的,嗯!加油、加油、加加油。

从珍珠的到来到它的离去这件事,对我有很大的启发,先说珍珠的到来吧!让我知道干什么都不容易,不过如果你喜欢干这件事你就会忘了累和痛苦,最后获得的是快乐。再说它的离去吧!让我知道了人和动物一样生命都只有一次,老天在喜欢你也只给你一次生命不会给你第二次,我要用我这一次生命好好学习完成爸爸妈妈没有完成的梦想。

Why should people care? Because we need animals, and because once they are gone, there will never be any more.Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or planton the danger list. Slowly, the number of some animals in danger is growing.

Do you love animals? Animals and human beings are the owner of this beautiful planet that we all have the right to freedom of survival on this planet, have the right to enjoy nature gives us everything, this is our common homeland.

However, in the eyes of some people, but these animals is some lose your life, no life, no feelings. They are just delicious or money can buy the things on the table, the people in order to kill all kinds of animals and birds, fur clothing and food in order to the so-called "mouth" a lot of killing selling duck, full mountain bird nets, traps set, overrun by shocking animal remains, such as there are numerous unsubstantiated reports that have appeared. Dropped sharply in animal species, some animals have become extinct or endangered, too cruel. Dont know what those people long is the heart of stone, if left unchecked, we can no longer hear birds schools of thought contend, and cant see the fish live the bottom of the sea, many animals will become "according to historical records". The world will no longer be rich and colorful, the world will only greedy human lonely and sad. This is the tragedy of the entire human race.

Have a word said good, protect animals is to love ourselves, any kind of animal in nature are one part of the food chain, a ring is indispensable, the lack of any one ring will upset the balance of nature, to suffer or ourselves, many animals are friends of human beings, human beings are not often divides into the animal beneficial insects and pests? If beneficial insects is destroyed, it is how a situation? If extinction beneficial insects pests also ceased to exist, the survival of the animal extinction is closely related to our life.

To protect animals, cherish life, is that we call, from the bottom of his heart. We should start from around things, care for small animals, care for the weak life, refuse to eat wild animals, refused to wear clothes made of animal skins, animal bones, accessories and supplies. Resolutely resist the behavior of animal cruelty, and animals together for us to build a harmonious coexistence of their homes.

你热爱动物吗?动物和人类一样都是我们这个美丽星球的拥有者,都有权利在这个星球上自由的生存,都有权利享有大自然赋予我们的一切,这是我们共同的家园。

然而在有些人眼中,这些动物不过是一些任人宰割、没有生命、没有感情的东西。它们不过是餐桌上的美味或能换取金钱的物品,人们为了皮衣和食品杀死各种飞禽走兽,为了所谓“口福”大量捕杀贩卖山珍野味,满山的捕鸟网,遍野的捕兽套,令人触目惊心的动物残骸,诸如此类的报道屡见不鲜,不绝于声。致使动物种类大幅减少,有些动物已经灭绝或濒于灭绝,太残忍了。不知道那些人长的是怎样的铁石心肠,如果任其发展下去,我们再也听不到百鸟争鸣,再看不到鱼翔海底,许多动物将成为“据史料记载”。这个世界将不再丰富多彩,这个世界将只剩下贪婪人类的孤独和凄凉。这是整个人类的悲哀。

有一句话说的好,保护动物就等于爱护我们自己,大自然中的任何一种动物都是食物链的一环,一环不可缺少,缺少任何一环都会打乱自然界的平衡,遭殃的还是我们自己,许多动物都是人类的朋友,人类自己不是经常把动物分为益虫和害虫吗?如果益虫都灭绝了,那会是怎样一种情况呢?如果害虫灭绝益虫也不复存在,动物的生存灭绝与我们的生活密切相关。

保护动物,珍惜生命,是我们从心底发出的呼唤。我们要从身边的小事做起,爱护小动物,爱护弱小生命,拒绝食用野生动物,拒绝穿戴使用兽皮、兽骨做的衣服,饰品和用品。坚决抵制残害动物的行为,为我们和动物共同营造一个和谐共存的家园。
