篇1:六年级上册第七单元作文300字保护动物
全文共 1092 字
+ 加入清单保护动物,是我们人人都要做到的,许多人任意去猎杀动物,虽然现在的人都说要保护动物,但是还有很多顽固的人不听,继续猎杀动物,人类拿动物来观赏、卖钱,用兽皮做大衣但你们有没有想过,如果你是一只动物,却遭到了人类的猎杀,你会怎么想,你愿意吗,你愿意被猎杀吗?你绝对不愿意,有些人说:我又不是动物。但你们有没有想过动物们会怎么想吗?现在人类大量捕杀动物,动物会甘心吗?不,不会,永远不会。它们不愿意死在人类手里。它们愿意被你们猎杀吗?不,它们有一千个不愿意,一万个不愿意,一亿个不愿意
有些人虽然知道怎样去爱护动物,可是他们只会假惺惺地去教育别人,而自己却照样破坏环境,照样兴致勃勃品尝野味。就拿印度洋毛里求斯群岛上生活的渡渡鸟来说,由于它身上的肉鲜美无比,所以遭到当时人类的大量捕食,在十七世纪就已告灭绝。但是如果当时人们有动物保护意识的话,就不会造成渡渡鸟的灭绝。
还有鲸,鲸不是让你们随意捕杀的,鲸是被杀掉一头就死一头的,不像小鱼小虾那样多,如果我们把鲸杀掉了,那我们的子孙后代,他们不是看不到鲸这种动物吗?
现在,有些动物已经灭绝了,鳄鱼虽然凶猛,但人类更凶猛。就是因为有些动物身上的器官具有突出的经济价值,由此成为被人类掠夺利用的对象,成为动物灭绝的主要因素。鳄鱼长着锐利的牙齿,和硕大的食物胃口,我们都说鳄鱼可怕,但鳄鱼更怕人类,在人类的眼中,鳄鱼皮可以制成行李箱,手提包,钱包,鞋等物品,所以鳄鱼,现在已经成为快要灭绝的动物了。
《金色的脚印》,这篇文章讲了正太郎家捉来了一只小狐狸,两只老狐狸想尽办法就救出小狐狸,正太郎很同情小狐狸,他偷偷地给老狐狸投送食物,于是,他们之间建立了亲密,信任的关系,后来两只老狐狸救了正太郎,最后,小狐狸回归了大自然,两只老狐狸是多么高兴!这篇文章赞美了人与动物之间互相信任,互相帮助,和谐相处的美好关系,也展现了动物之间的浓浓亲情。我们就要向正太郎学习,他帮助动物,动物也救了他,这样不是很好么?为什么人们还是要捕杀动物呢?
在此,我呼吁人们,不要再破坏自然界中的花草树木,不要再乱杀一禽一兽,不要再杀害我们的朋友,要保护好自然界中的一个个生灵。消灭动物,就是在消灭人类自己。如果有一天世界上的动物全都消失了,那人类还能生存吗?要保护动物,珍惜这自然界里的每一个生灵吧。
朋友们,动物是大自然留给人类的无价之宝,它是我们人类的朋友。它们的生衍死灭与我们人类的生活是密切相关的。动物的大量毁灭对人类将产生严重的不良后果,造成生态严重不平衡,从而使人类的生存环境遭到破坏。让我们从现在做起,从我做起,保护动物,使世界变得更美好吧!保护动物,就是保护人类自己!

先如今环保已经成为了我们必做的事,因为现在地球上的环境正受到威胁。
现在,我们知道地球已经开始变暖,寒冷地方的冰已经开始融化,变成的水使水平面越来越高,让许多沿海的国家被淹没。更多的土地沙漠化,天灾不断来袭,使我们的生活不再那么无忧无虑。
首先,我们必须从身边做起。
大片森林被不断砍伐,汽车尾气不断排放……这些首先就会直接影响到我们的生活,因为这些让我们“不敢呼吸”。所以,这些问题最好的解决方法就是少开车,多骑自行车,而且,骑自行车也很有益身体健康!。可虽然一直这样说,而且说了也不只一次,可为什么还是有那么多的车在路上呢?所以,这个方法实在,有点不实用。
最简单的就是种树了,树是人类的好朋友,他们能帮助人类许多事,比如净化空气啦,等等。所以,多种树,这个方法很实用!

等我回过神来已经有许多小孩围在了妇女的身边,每个人都想玩弄一下这个可爱的小东西,“让我来玩一下!”“能给我摸摸吗”“真可爱”“它的毛真滑!”……到等他们都渐渐散去后我与小相思鸟的目光发生了碰撞,我仿佛能感受到小鸟眼神中的痛苦与哀求。我于心不忍,但总不能坐视不管让鸟儿饱受痛苦吧?当我还在思索时又有一个调皮的小男孩走了过来抢走了红嘴相思鸟,他一边拨弄着小鸟深绿色的翅膀和小小的爪子,向前走去。小鸟似乎在发抖着,更是用一种忧伤的眼神看着我,指望有一位救星。我这才鼓起勇气向小男孩走去小声地提醒道:“快放了它吧,它也很可怜。”
结果真是出人意料,那个小男孩一声不响地推出手,慢慢地端详着这只美丽的小鸟,最后张开双手放飞了这只可爱的小鸟。我们抬头观望,天空中却不见了它的身影,耳边却响起了一清脆的鸣叫,鸟儿,是你吗?是你,在谢谢我吗?

No one can have failed to notice the fact that water shortage is a grave problem with which the whole world is confronted. Actually, it has become so widespread that it has severely affected peoples daily life and hindered the development of the global economy.
A number of factors could account for the problem, but the following might be the critical ones. First, with the development of agriculture and industry, an increasing amount of water is needed. Secondly, the ever-increasing population is another leading cause of water shortage. Besides, the global tendency of warming up also contributes to the problem. Whats worse, pollution and waste of fresh water aggravate the situation.In view of the seriousness of the problem, effective measures must be taken before things get worse. First, it is essential that laws and regulations be worked out and enforced to protect water resources. Secondly, people should enhance their awareness of saving water. With these measures taken, it is reasonable

篇17:写濒临危机动物的英语作文北极熊
全文共 3755 字
+ 加入清单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。
篇18:关于保护动物英语词
全文共 1698 字
+ 加入清单Animals Need Protecting 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 aloneare 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.

最近我发现我们的学校发生了一些不好的现象。
平时十分整洁干净的校园,最近却变的有些脏兮兮的,一些角落里或者是走廊里,都能看到同学们用来装事物的塑料袋,还有一些水果皮、碎纸屑和吃完小零食以后扔掉的包装袋。我们学校是每个班都有一定的卫生打扫的负责区域的,每天每班都会安排学生打扫,这些垃圾肯定都是在同学打扫完卫生之后,又有人丢下的,我觉得这些同学的素质真的很低,都不知道珍惜别人的劳动成果,不知道保护校园的环境。
同学们,不以善小而不为,不以恶小而为之,大家携起手来,共同保护我们的校园环境吧!

地球是我们的家园,环境与我们的生活息息相关。人类大量的消耗水资源和污染环境,已经把一个美丽的地球毁的不象样了。水渐渐少了,动植物濒临灭绝……这一切都是因为人类不注意保护环境造成的。
人们到处砍伐树木,现在全世界平均一年砍掉1100万公顷森林,这是一个多么大的数字啊!人们还随手丢垃圾,那发臭的河面上漂浮着垃圾、那肮脏的树枝上挂着塑料袋、那黑黑的草地上堆着果皮和纸屑。环境遭到了很大的破坏,清清的小河、绿绿的森林、蓝蓝的天空都消失的无影无踪了,地球渐渐被毁灭,人类也渐渐死亡。
原来,地球有着清澈的小河,绿绿的森林,蓝蓝的天空。古代,有多少诗人赞美过地球美丽的环境啊!人类既是环境灾难的制造者,也是环境灾难的受害者,更应是环境灾难的预防者。我们要从自己做起,从小做起,携起手来,共同保护环境,保护我们的家园。为我们的孩子们留下碧水、森林、蓝天。
让我们为了美好的明天共同努力吧!
