关于北极熊中学生英文演讲稿

Unlike Black and Grizzly bears, which are primarily nocturnal, the Polar Bear may be active at any time of the day or year, searching for prey on long summer days and sometimes on long winter nights. Adaptations to its Arctic habitat include its fur color, which blends with the snowy environment and so provides useful camouflage for capturing prey; its large size, which helps maintain body temperature by reducing surface-heat loss; and its furred feet, which insulate against cold and provide traction on icy surfaces. Because the hairs of its waterproof coat are hollow, they are especially insulating and increase the bear's buoyancy when swimming. An excellent swimmer, it paddles at about 6 1/2 mph (10 km/h) with the front feet only, hindfeet trailing-a trait unique among four-footed land animals-and can remain submerged for about two minutes. While swimming or treading water, it stretches its long neck for a better view, as it does on land. Owing to the scarcity of plants in its icy habitat, the Polar Bear is the most carnivorous North American bear, with canine teeth larger and molariform teeth sharper than those of other bears. An acute sense of smell enables the Polar Bear to locate prey even when it is hidden by snow drifts or ice. It stalks young seals and Walruses, and sometimes adult seals, often by swimming underwater to their ice floes. While hair seals are its staple, it also feeds on fish, birds, bird eggs, small mammals, dead animals (including whales), shellfish, crabs, starfish, and mushrooms, grasses, berries, and algae, when available. The Polar Bear hollows out a winter den in a protected snowbank, where it retires in a lethargic condition. Females den from November to March, during which time they give birth. Males den for much shorter periods, usually from late November to late January, but may be abroad occasionally at any time of the year. Cubs remain with their mother about a year and a half, denning with her the winter after their birth. The lowlands of Hudson Bay and James Bay, one of the world's largest denning areas for Polar Bears, is the only known region where Polar Bears den in earth rather than in snow. They excavate caves in lake and stream banks and peat hummocks by digging down to the permafrost. This area is unusually far south for the species, and it is believed that they use the permafrost dens again in summer to cool off. No large denning areas have yet been found in Alaska; some Polar Bears in that region may winter in Siberia, drifting across to Alaska on ice floes in spring. Polar Bears are a source of food and hides for Native Americans.

Animals Protection

Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.

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.

关于保护动物的英语演讲稿回答必好评

今天很高兴由我来进行演讲。今天我要说的话题是动物。我一直认为动物是人类的朋友，它们不会像人类那么复杂，而且常常给我们带来欢乐和满足。

I am very glad to give a speech today. The topic of my speech is the animal. I always think that animals are the friends of our human beings. They are not so complicated as our people, and they can always bring us plenty of happiness and satisfaction.

从我小时候起，就一直养着动物。比如猫，狗，鸭子等等。虽然有时候会觉得喂养它们很麻烦，但是每次想到平日里它们带给我全家的快乐，就会觉得很多辛苦都值得。你可以试想，当你拖着疲惫的身子回到家时，狗狗快乐的摇着尾巴向你扑来。那种很温馨的感觉，是只有宠物才能带来的。

Since I was a child, I have been keeping animals, such as cats, dogs, ducks and so on. Sometimes I feel a little troublesome to feed them, but everytime I think about the happiness they have brought to my family, I will find that it is worth doing it in spite of so much hard working. You can imagine that, when you come home with your tired body, dogs are rushing at you and swinging their tails happily. That kind of warm feeling can be only brought by the pets.

不论是家养动物，还是野生动物，都是很可爱的。可是现在却有那么多人用残忍的手段伤害它们。我对这种人简直难以理解。你可以不喜欢它，甚至可以讨厌它，但是你没有权利伤害它。

Both the domestic animals and the wild animals are lovely. However, they are being treated cruelly by lots of people at present. I can't understand those people. You may not like animals, even you could hate them, but you have no rights to hurt them.

每个生命都是平等的，每个生命都有快乐的生活的权利。人类不能为了私欲而伤害那些无辜的生命。

Every life of the living creatures is equal. Every life of them has the right to live happily. Human beings mustn't hurt those innocent creatures for our personal desire.

动物们把我们当作朋友，我们也应该让它们有一个幸福的生活。

Animals regard us as their friends, so we should let them enjoy their happy lives too.

Now, that is all of my speech today. Thanks for your listening.（这就是我今天的演讲了，多谢收听）
