导语：人类正试图猎取野生动物以获取更大的利润，下面是yuwenmi小编为大家整理的优秀作文，欢迎阅读与借鉴，谢谢!

As is often read in the newspaper reports, wild life especially the rare species is threatened with extinction. Human beings are making attempts to hunt wild animals for a big profit., which, of course, results in a sharp decrease in the number of animals. So it is high time for us to take quick action to protect them. First of all, its quite necessary for every citizen to realize the importance of animal protection. Only by knowing its importance can people develop a sense of responsibility. People will surely take it for granted to have the duty to prevent any killing of wild animals. So a national publicity campaign should be launched, thus giving animals a good living environment. In addition, the government should pass some laws to forbid any hunting of rare animals. We dont expect anything harmful to wild life to happen again.

If everyone is involved in the protection of wild life, were sure man will be a good friend of animals rather than their enemy.

正如报纸上经常看到的那样，野生生物特别是稀有物种面临灭绝的危险。人类正试图猎取野生动物以获取更大的利润，当然，这会导致动物数量急剧减少。所以现在是我们采取行动保护他们的时候了。首先，每个公民意识到保护动物的重要性是很有必要的。只有认识到它的重要性，人们才能产生责任感。人们一定会想当然地认为有责任阻止野生动物的捕杀。开展全国性宣传活动，为动物创造良好的生存环境。此外，政府应该通过一些法律，禁止猎杀珍稀动物。我们不希望发生任何对野生动物有害的事情再次发生。

如果每个人都参与野生动物的保护，我们相信人类将是动物的好朋友，而不是敌人。

There are more and more endangered animals at present，so how to protect them has been our task of top priority .Its wrong for people to hunt animals for their meat and feather，for they are our good friends。We should protect them instead of killing them。Giant pandas，which are one of the endangered animals，live in the forests and live on bamboo lealves。They can just live safely in the natural protection zones。We should stop killing animal and protect them。

Some people think that human needs for farmland, housing, and industry are more important that saving land for endangered animals.

Do you agree or disagree with this point of view? Why or why not?

Use specific reasons and examples to support your answer.

In the past, there have been many endangered animals. Now they are extinct. Does it matter? Has our environment been affected by their absence? Has the quality of our own life been changed? The answer to these questions is “Yes.”

Yes. It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks. There is a delicate balance of nature. If one small part is removed, it will effect all the other parts.

For example, if certain trees are cut down, bats will have no place to roost. If they cannot roost, they cannot breed. If there are no bats, there will be no animal, or bird to eat certain insects that plague our crops.

Yes. Our environment has been affected by the absence of certain animals. Certain flowers are pollinated by butterflies, which migrate from Canada to Mexico.

Some of the breeding grounds of these butterflies were destroyed. Now these flowers are disappearing from certain areas. We will no longer be able to enjoy their beauty.

Yes. The quality of our life has been changed America used to be covered with giant trees. Now we have to visit them in one small park.

Rain forests around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.

I would encourage us humans to look for other alternatives for our farmlands, housing, and industries. We have alternatives; the animals do not.

I like small animals have kitten doggie and so on, but my favorite is I buy small crabs.

Remember it was a Sunday, Zhao Yifan to seek me to play, we go out and see there is an old woman in sell crabs, we went to the old woman beside him, said: "grandma, we are going to two crabs." grandma gave us two, we returned home I hurriedly put a basin of wash in clean water, put the crab to the inside, Im afraid crabs dont adapt to the environment, and to put too many POTS I pick up the small stone on the beach, I carefully observe small crabs, see them as a battle-hardened general, commanding, a pair of round eyes can spirit, I touch it, its big claws waving up immediately.

我喜欢的小动物有小猫小狗等等,但我最喜欢的还是我买的小螃蟹.

记得那是一个星期天,赵逸凡来找我玩,我们一出门便见有一位老奶奶在卖螃蟹,我们走到老奶奶身旁说:"老奶奶我们要两只螃蟹."老奶奶给了我们两只,我们回到家我连忙把一个脸盆洗了洗放进净水,把螃蟹放到了里面,我怕螃蟹不适应环境,又往盆里放了许多我在海边捡的小石头,我仔细观察小螃蟹,只见它们像久经沙场的将军,威风凛凛,一双圆溜溜的眼睛可精神了,我一碰它,它的大钳子立刻就挥舞起来.

有一天,我去看螃蟹发现水里有许多土和树叶,我就给它换水,我捏着它,它还以为我要伤害它,就拼命的挣扎,过了一小会它没有力气了,我接好水正想把它放回去时,它用钳子夹住了我的手指,我怎么甩也甩不掉,我只好服输把它放到水里,它这才慢慢地松开了钳子.

They move from town to city or to suburb, from high school to college in a different state, from a job in one region to a better job elsewhere, from the home where they raise their children to the home where they plan to live after retirement. With each move they are forever making new friends, who become part of their new life at that time.

[我喜欢的动物的英语作文

Dear classmates,

As we know, some animals are dying out for various reasons. There is no doubt that animals are our friends. With World Animal Day coming near, what should we do to protect animals?

First of all, we should forbid people’s killing animals at random. Second, we should do all we can to protect animals’ living environment. With their living environment destroyed, the animals will become extinct sooner or later. Third, we should try our best to make everyone realize the importance of protecting animals. In a way, protecting animals means protecting ourselves.

Dear classmates, let’s start now and make every effort to protect animals—our good friends!

The small white rabbit is very cute, a snow-white hair feels soft, like Snow White. Two eyes red and big, like a ruby. Embedded in a dialogue red long ears, like the maize leaves. Eyes under the long nose, a small, short, there are a small and exquisite of three petal mouths. Everyone knows the rabbit loves to eat turnips, but little mouth zhang, how to eat? So they turned into three petal mouths.

I think the rabbit is supposed to be nutrition experts, its very nutritious food, carrots, white radish, green vegetables, cabbage... If you look carefully, you can also see its short tail in eating shake? Remember once went to the park to feed the rabbit green vegetables, there is a rabbit hungry panic about, I just carefully put the food in the past, it suddenly descended, bit green vegetables in the mouth, I threw the vegetables a scared, back several paces. See it exhaled to eat it, a little later, green vegetables into the belly.

The small white rabbit character gentle, clever, like easily prone on the ground, but sometimes also like we naughty, games will to fight. They run very flexible, leap to jump, know why? I go to the Internet to check the information, the original rabbit front legs short and small, thick and long hind legs, so start to jump and jump. Ha, too funny!

The small white rabbit, I really like you!

小白兔的样子非常可爱，一身雪白的绒毛摸起来软绵绵的，真像白雪公主。两只眼睛又红又大，像红宝石似的。一对白里嵌红的长耳朵，像玉米叶子一样。眼睛下面长了一个又小又短的鼻子，下面还有一张小巧玲珑的三瓣嘴。大家都知道兔子爱吃大萝卜，可是小嘴张不大，怎么吃呢?所以就变成了三瓣嘴。

我想兔子应该是营养专家，它吃的食物非常有营养，有红萝卜、白萝卜、青菜、白菜……如果你仔细观察，还可以看到它那短小的尾巴在吃东西时会抖动呢。记得有一次到公园去给兔子喂青菜，有只兔子大概饿慌了，我刚小心翼翼地把菜伸过去，它就猛地扑了过来，把青菜咬在了嘴里，吓得我把青菜一扔，退后了好几步。只见它大口大口地吃了起来，不一会儿，青菜就进了肚。

小白兔性格温顺、乖巧，喜欢轻松地趴在地面上，但有时候也和我们一样顽皮，会游戏会打架。它们跑起来很灵活，蹦蹦跳跳的，知道为什么吗?我到网上去查了资料，原来兔子前腿短又小，后腿粗又长，所以走起路来又蹦又跳的。哈，太有趣啦!

小白兔，我真喜欢你!

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。
