一说到动物，人们就想捕回去杀死吃它们的肉和刮下它们的皮毛来赚钱，可是人类万万没有想到的是由于乱捕滥杀等对待动物，使得动物的种类一天天减少，而有的动物已经到达“濒临灭绝”据新闻报道：野生东北虎在我国不足500只、而非洲象只有约47至69万只、长江江豚不到1500头、而东部美洲狮已经灭绝、白令海牛也已经灭绝、也使生物圈和食物链遭到严重破坏，这都是人类在地球上一一所犯下的罪行，我们要保护这些美丽的生灵、保护生物圈、保护食物链。

为了保护动物;国家在各个地区建立动物园;除此之外，在一些地区还建立自然保护区和自然风景区;另外还在各省各地区设有省级林业局和市级林业局;还有在森林设有森林派出所;国家在动物界设有国家几级动物的级别;国家还分别颁布和颁发了保护动物的法律和文件。

如果人类一错再错下去的话，那么这个人类赖以生存的家园就会毁于人类手中。

我们和动物一样都要生活，如果我们把地球上的动物全部杀死，最终伤害了我们自己。

我们是动物的朋友，动物也是我们的朋友，是生存在赖以生存的朋友。

我们要保护动物，让它们给我们造福，保护动物是我们的责任，保护动物刻不容缓。

我总结出一条一荣一耻：“以保护动物为荣，以捕杀动物为耻”。

目前，濒危的动物正在日益剧增。如何保护濒危动物成了我们的当务之急。人们疯狂的捕杀动物，为了它们的肉、皮毛。我们这样做是不对的，因为动物是我们的朋友，我们应该保护它们，而不是将它们赶尽杀绝。大熊猫就是濒危动物的代表，它生活在森林里，以竹子为食，它们仅仅依靠着自然保护区生存。我们应该停止对动物们的捕杀，更好地保护它们

去参观动物园的英语作文3

The zoo provides the animals the comfortable and safe living conditions that can not be found in other places.

If the animals get hurt or ill, certain people will take care of them to prevent futher danger caused by the diseases.

Good opportunities for the people in the city especially those children who dont have the chance to set foot in the wild world.

Watching the animals in the zoo may give the parents a good chance to teach their children to love the animals and the world.

The parents can get the children know more about the animals in the zoo by watching listening even smelling instead of just looking at the dull pictures in the books.

Animals are our good friends. People should be friendly to them. But now, many people in China as well as in the world kill animals in order to get money. Its well known that there are many kinds of rare animals in China, such as pandas, golden monkeys and so on. Some people catch or kill them. They use their furs and skins to make clothes and shoes or eat their meat. As a result, a lot of rare animals have disappeared.

What a pity!

At present, our government have made some plans to punish these people. Recently, some nature parks have been built. Lots of money collected for protecting them. For example, some students put on perfom ances or have other kinds of activities to collect money for rare animals.

Its our duty to protect wild animals. As nature is like a big family, man and animals must live together in it peacefully. We must keep the balance of nature. If we do like this, our world will become better and better.

动物是人类的好朋友，人们应该善待它们，但现在，中国和世界上的许多人为赚钱而捕杀动物。众所周知，中国有许多珍稀动物，如熊猫、金丝猴等。一些人捕杀它们是为了用它们的皮毛制衣制鞋，或是为了食用它们的肉。

结果大量的珍稀动物死亡了，真可惜呀!

目前，我国政府已制定出有关严惩不法分子的法律;近来又建起了一些自然公园;人们：也捐款来支持保护动物的活动，如，有些学生通过义演或用其它方式为保护珍稀动物积极筹款。

我们有义务保护野生动物，因为自然就像一个大家庭，人类和动物必须和平共处：我们必须保持生态平稳。

如果人类能这么做，这个世界就会越来越好。

Everyday, they play with each other happily. One day, I couldn’t find them. I asked my mother: ”Where are they? ” My mother told me that She didn’t know. At last, I found them in the grass. They were very dirty. I was angry, but when I looked at their lovely faces, I was happy again.I love my little rabbits, and they love me. They are my good friends forever.

【翻译】

每天，他们互相玩耍。有一天，我找不到他们。我问妈妈：“他们在哪里?“我的母亲告诉我，她不知道。最后，我在草丛中发现了他们。他们非常脏。我很生气，但是当我看着他们可爱的脸，我又开心了。我爱我的小兔子，他们也爱我。他们永远是我的好朋友。

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后，北极熊就会出发去寻求它们最喜欢的食物：富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹，所以它们进入禁食期。至少，情况应该是这样。但是由于地球变暖，温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为，北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求，进而生存下去，这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论，即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究，还有早期的探险者日志，我们很早以前就知道，北极熊会以陆地食物为食。但是辩论的焦点在于，这些食物是否能增加北极熊的能量。”换句话说，这些替代食物能否为北极熊提供足够的营养，弥补不能进食海豹带来的损失?

为了解开这个疑惑，皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算，从表面上看，北极熊在这段时间食用了陆地食物。随后，他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间，北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”，但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明，陆地食物不能为北极熊提供足以抵消大量损失的能量。所以，北极熊可以从食用海冰下面的食物转向食用陆地食物，并帮助它们对抗日益延长的无冰季这个观点，并没有在这项数据中得到证明。”

问题是，北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础，而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是，将脂肪吸收进它们的系统中，然后把这些脂肪放在身上以增加体重，这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育，它们必须要去猎食，可是它们不能在漫长的无冰季期间一直不进食。所以，随着北极地区变暖，较小的北极熊将会大批死亡。这使这些物种的生存成为问题。

The snake is a long and thin animal that lives in grass or other dark places.A snake has no legs or feet,but it can move very fast on its stomach.Snakes usually have green,yellow or black skins,which make them difficult for their enemies to find them.Some kinds of snakes live in water.They can swim as freely as fish.

Cats are cute animals,they are very special as well.

It has pointy ears, round eyes,little claws,and short but soft fur.Cats like eating fish and mice.They like to keep themselves clean, they do that by licking their fur.Also they are nocturnal animals, they sleep in the daytime and do most of their movements at night.

We should love cat, because cats are our friends,too.

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.

dogs

I like dogs.Many people like dogs.Dogs and people are friends.Some dogs also do different linds of work.Dogs are used to keep watch.They tell people when dangeris coming.Some dogs are used to keep people safe.They sre also used to move animals like sheep or goats.Some dogs are used for different kinds of hunting and some dogs help the police.

Today is Saturday. In the morning my father took me to the zoo.we went there by bus.There were many animals in the zoo.We saw monkeys ,elephants,dolphins,lions and so on.The monkeys were very clever.they could work out some maths problem.The elephants were very strong.I had a good time.

今天是星期六。在早上我父亲带我去动物园。我们乘公共汽车去那里。动物园里有许多动物。我们看到了猴子、大象、海豚、狮子等等。猴子是非常聪明的。他们可以解决一些数学问题。大象非常强壮。我有一个美好的时光。

When I was very small, I could see many birds flying in the sky when I looked at the sky, but as I grow up and move to the city, I find less birds in the sky. It is because the environment has been polluted and many birds are dying. We can do small things to protect the environment, so that the animals can live with us.

在我很小的时候，每当我仰望天空的时候，我都可以看到许多鸟在天上飞，但是当我长大后，搬到了城市，我几乎没见过有鸟儿在天空中飞。因为环境被污染了，许多鸟面临死亡。我们要做些小事来保护环境，让动物能和我们共存。

There is no denying the fact that keeping pets is a hotly debated topic today. Some people claim that keeping pets is a good thing to do. They believe that pets, like cats and dogs, can help relieve the loneliness suffered by senior citizens and other social members who are confined to their homes for this reason or that. They also argue that keeping pets helps mankind understand animals world and develop positive feelings toward them.

有一个不可否认的事实，即养宠物是当今一个被热烈讨论的话题。有的人认为养宠物是一件好事。他们认为宠物，比如猫和狗，有助于缓解年长者和那些由于这样那样的家庭原因限制的社会成员的孤独感。他们还认为，养宠物有助于人类了解动物世界，培养对它们的积极态度。

Others, however, hold the opposite view. They regard keeping pets as a useless but harmful thing to do. Firstly, pets can transmit diseases. Secondly, the noises and dung of pets are sources of pollution. Last but not least, as many rare birds and animals are kept as pets, they will surely be hunted on a large scale, which means a threat to the balance of the ecosystem.

然而，其他人持相反观点。他把养宠物当做是无用而且有害的事。首先，宠物可以传播疾病。其次，噪音和宠物粪便是污染的来源。最后，许多珍禽异兽作为宠物饲养，他们一定会被大规模猎杀，这意味着威胁到生态系统的平衡。

Weighing the arguments of both sides, I am inclined to agree with the latter. Anyway, we can lessen our loneliness and express our love toward animals in other ways. And it is my beliefs that only by placing man and other species on an equal basis can us expect to have a lively and colorful world.

权衡双方的论据，我更倾向于同意后者。不管怎么样，我们可以通过其他方式来减少我们的孤独和向动物表达我们的爱心。我相信，只有在人类和其他物种平等的基础上，我们才能期待有一个生动多彩的世界。

再说盘中餐吧，许多大人喜欢吃野生动物，像青蛙、蛇……这样，使得许多动物都灭绝了!而且对人体也有很大的危害!据说2003年“非典”就是因为这样引起的!我诚恳的告诫大家：“请大家不要再吃野生动物了!”

还有，许多人特别爱吃青蛙，所以有许多人为了赚钱，残忍的杀害了青蛙拉到菜市场去买……请问那些杀害青蛙的人，你们在杀害青蛙的同时，有没有想过，青蛙是人类的好朋友，他们能帮农民伯伯捉害虫、保护庄稼呢?

动物是人类的朋友，请大家保护动物吧!保护动物，人人有责!
