Protect Traditional Chinese Culture

The passage mainly tells us the importance of protecting traditional Chinese culture, which is challenged or facing extinction because of the developing society and changing lifestyle. Besides, China is nationwide sparing no efforts to do it.

The protection of national and folk culture is of great significance to Chinese cultural diversity and also to the harmonious development between local economic and social development. It is reported that the Guangdong government pays special attention to protecting Chaoju(潮剧)， a local drama born in Chaozhou in the eastern Guangdong province.

In my opinion, some measures should be taken to protect traditional culture effectively. To start with, we should make a law to regulate the society’s performance. Besides, we should draw more people’s attention to it, for the more they know about the importance of culture protection, the stronger the support we can get from the public.

In a word, it is high time for us to treasure and develop our own valuable culture.

寒假里，爸爸、妈妈带着我来到了杭州动物园。那里我去过好多次，但这次并不像以前一样兴奋。以前看到奔跑的骏马，上窜下跳的猴子，以为它们过得很快活。那天，我却看到它们伤心和无奈的样子。在这酷暑里，马儿不知要为多少游客服务，它们疲惫地耷拉着脑袋。上窜下跳的猴子被训练员鞭打，很可怜的样子!

走着走着，我又看到很多小动物被关在笼子里，像小鸟、小兔、小狗都关在很小，很湿的地方，小鸟“叽叽喳喳”地叫着，好像在说：“我又不是犯人，干嘛把我关起来，生活在比监狱还差的地方，真是太不公平了!”小兔“吱吱”地叫，好像在说：“救救我，我不想生活在这样的地方!”小狗“汪汪”地叫，好像在说：“你们还说动物是人类的朋友，对待朋友是这样子的吗?”

我们来到了黑熊住的地方，很多游客都不停往里面扔东西，根本没有注意旁边的警告牌“勿扔食品!”管理员告诉他们不要这么做，他们不听劝告，继续往里扔东西。在报纸上曾经报告过一个大学生为了做实验竟然把硫酸泼在一只黑熊身上，使它痛苦地倒下了，身受重伤。为什么那位大哥哥会这样残忍?难道他没有想过这样黑熊会很痛苦吗?

人们常说：“动物是人类的朋友。”对待朋友是这样的吗?对待朋友要像对待自己一样，这样才公平。动物是人类朋友，我们就该保护动物，善待朋友。

Through the ages, the earth mother with sweet milk feeding countless generations. The original she was decorated lovely young players. But, now human to its own interests, tortured her.

人人都要保护环境，这是大自然的规律，如果不保护环境，世界就会被污染。

保护环境是从一点一滴的小事做起，而我却没有做好。有一次过新年，我们去顺峰山公园游玩，骑完自行车，我们个个都饿了，我们买了一小包零食来吃，而我，吃完零食，我因为高兴过头了，所以随手就把我吃过的7包零食的包装扔在地上，然后我进去便利店里面看电视，尽管今天的电视剧很好看，过了半个小时，我把以前妈妈跟我说的话忘得一干二净，我所有的心思都沉迷在这个电视剧里面。在过了三十分钟，我才想起来，可是，这时候，妈妈生气的走过来说：“你这个臭丫头，难道我以前跟你说的要保护环境，你都忘了吗?”我说：“我不是忘了，我只是顾着看电视。”妈妈说：“看电视重要一些，还是捡垃圾重要一些?”我说：“捡垃圾。”妈妈说：“那你快点捡呀。”

然后，我捡起一小堆垃圾，扔进垃圾桶，我不但向妈妈认错了，我也向顺峰山公园的每一个扫地阿姨认了错。因为，如果每个人都扔一块垃圾在地面，那么就会给清洁阿姨增加负担。如果你看见一块垃圾在地面，那你就弯弯腰，动动手，做一个保护环境的人，那么就会给清洁阿姨减少负担……

虽然这件事已经过去一年了，但是，这件事让我学会了，如果世界上都扔一块垃圾在地面，那么整个地球就会变成一片废区，所以我们每个人都要保护环境，保护地球，世界才会更美好!

Every year on October 4th is the World Animal Day. It is proposed by the Italian monk St Francis in 12th century. He lives in the forests of Assisi Island for the long time, building a good relationship with the animals. So he asks people to express thanks to the animals on October 4th. He sets a good example for our human beings about how to deal with the relationship with animals. In order to memorize him and what he does, we make October, 4th to be World Animal Day. Nowadays, people from all over the world will hold various activities to celebrate on that day. The aim of this festival is to remind people to care for all animals and build a harmonious relationship with them.

每年的十月四日是世界动物日。它是由意大利修道士圣弗兰西斯在十二世纪提出的。他长期生活在阿西西岛上的森林中，与动物建立了良好的关系。所以他要求村民们在10月4日这天向动物表示感谢。他为如何正确处理与动物的关系树立了一个很好的榜样。后人为了纪念他和他所做的，我们把十月四号定为世界动物日。现在，在那一天来自世界各地的人会用各种活动来庆祝这一节日。这一节日的目的在于提醒人们关爱所有的动物，与他们建立和谐的关系。

A tiger is a kind of catamount animal.It looks like a cat,but much bigger than a cat.A tiger is very ferocious and it eats mainly meat.It has yellow and black streaks all over its body and it looks very beautiful.Its tail is long and strong and it can hit its quarry dying.

Tigers live in the thick forests and small animals in the forests are tigers food.

During the past years,many forests have been cut down and the living conditions of the tigers are becoming worse and worse.There are fewer tigers left in the world now.Tigers are the animals of the world,and they should have their own living spaces.We must do our best to protect the tigers and their living environment.

Here is a small zoo. I like the tiger，although they are very ugly，but very imposing. Also has the national treasure panda，they are a little shy，does not dare to look at us. Who are those? they are elephants，you look at they to be huge，also has a point to be interesting. I do not like the lion，they compare the tiger clown，is also unimposing.

This is the small zoo.

3.Recently, three owls appeared suddenly on our campus. They made me think of my pet from childhood. When I was little, we had an owl at home. It was small, gray, and had two big eyes. We liked it very much. Every time I went home, it greeted me by making “goo-goo” sounds. We always played with it and talked to it. It would blink its eyes just like it understood what we were saying. It was like my best friend. But when the weather became colder, we forgot to keep it warm, and it died. It made us sad for a long time, and it also taught me how important it is to take care of animals.

Environmental protection is everyones responsibility, we all know! But now the environment is not optimistic, such as: someone spit on the ground, someone littering, still pulling weeds, folding flowers. These are nothing, because some people, not only protect the environment, but also damage the environment. Because of the existence of this kind of person, so only in the sharp deterioration in environment, so we should protect the environment, more to damage the environment should be discouraged. In this way, the tree will be much, grass and flowers also lush, natural, such as dust storms disaster would not have happened!

Today, I let you see how should protect the environment. Some people might say, put a few piece of propaganda to protect the environment in the city brand is not good, in fact, this idea is wrong. Someone may say: this is not a propaganda to protect the environment? Of course not, because there are two reasons: 1, some people may watch brand every day, so I wont join the team to protect the environment. Will likely continue to destroy the environment and bad habits. 2, is the man looking at, but he didnt want to join the ranks to or dont want to protect the environment. From these two points can illustrate just a few propaganda brand is useless. Which someone may be eagerly asked: what! Method is very simple, as long as their faith to protect the environment, the people around will follow suit yourself!

The first step to protect the environment: learn how to protect the environment. Requirements: oneself to voluntarily protect the environment, not even in your environment, so that you even pipe request wont be able to reach others. To protect the environment the second step: advice others to protect the environment. Requirements: if see people littering or spitting, etc., should be up to dissuade immediately. Of course also want tube that yourself! To protect the environment the third step: make a collective to protect the environment. Requirement: let the dozens of people and as a collective, and protect the environment. If you do this at 3 o clock, then you are an "environmental small guards"!

This is my idea of protecting the environment. I now are trying to protect the environment, and you?

保护环境是大家的职责，大家都知道吧!但是现在的环境状况却不容乐观，比如：有人在地上吐痰，有人乱扔垃圾，还有人拔草、折花。这些都不算什么，因为还有些人，不仅不保护环境，而且还破坏环境。因为有这种人的存在，所以环境才在急剧恶化，因此我们要多加保护环境，对破坏环境的人应该劝阻。这样，树就会多了，草和花也茂盛了，自然，沙尘暴之类的灾难就不会发生了!

今天，我就让大家来看看应该怎样保护环境。有些人可能会说：在城市里放几块宣传保护环境的牌子不就好了吗，其实，这种想法是错误的。有人可能会说了：这不是在宣传保护环境吗?当然不是，因为这里有两点原因：1，有一些人有可能每天都不看牌子，所以就不会加入到保护环境的队伍中去。习惯差的，还有可能继续破坏环境。2，那个人看是看了，但他不想加入到这个行列中去或是根本就不想保护环境。从这两点可以说明光是几块宣传的牌子是没用的。哪有人可能会急切地问道：那该怎么办!办法很简单，只要自己要保护环境的信心，自己身边的人也会跟着做的!

保护环境第一步：自己学会保护环境。要求：自己要自觉地保护环境，不能连自己都在破坏环境，这样你就连管别人的要求都达不到了。保护环境第二步：劝告别人保护环境。要求：如果见别人乱扔垃圾或吐痰等，应该立即上去劝阻。当然自己也要管得知自己哟!保护环境第三步：让一个集体保护环境。要求：让几十个人并成一个集体，并保护环境。如果你这三点都做到了，那你就是一个“保护环境小卫士”了!

这就是我保护环境的观点。我现在也在努力保护环境，你呢?

[保护环境为题目的英语作文

动物是人类的好朋友，好朋友是不能杀害的，我们应该竭力保护它们，何况现在它们已经越来越稀少了。

世界上有许多野生动物都濒临着灭绝的危险，这又是谁的错呢?人类，是人类!假如人类不去乱砍伐树木，动物们就不会“无家可归”;假如人类不对大自然下“狠手”，动物们也不会这么快消失的……人类吃野生动物，得了许多疾病;人类使一种动物灭绝，导致多种动物灭绝，人类也就受到印象。总之，肇事者是人类，最后的受害者也是人类。

在南京大屠杀中，许多被保护的羚羊惨遭厄运;现在东北虎的生存空间已经不够，人类破坏了它们的家园;大熊猫是人类皆知的动物，虽然它们过着“衣来伸手，饭来张口”的生活，可有谁能预测它们还能活多久呢?……种种“案件”表明罪魁祸首就是人类。

动物们是保护地球的一根根链条，就算它们不是珍稀动物、国家级保护动物，我们都有责任去保护它们，而不是破坏它们的生存空间。它们是支撑地球生命的铁环，如果这根铁环中少了一种动物，那链条随时可能断裂，人类也就随时会灭亡。到了那时，就算你再怎么有钱，再怎么有权，也挽回不了你的生命呀!小沈阳说的对：“钱乃身外之物”，你用你的钱财去吃野生动物的原因就是让别人知道你是大富翁。这样做就大错特错了，吃野生动物不仅对自己无利、对别人有害，国家还严刑惩罚呢!真是害人又害己呀!

让我们一起携手保护动物吧!它是地球母亲的孩子，同我们是姐妹，也是世界的一份子，还是我们的好朋友呢!你忍心杀害我们的好朋友吗?

In the animal kingdom, both predators and prey species utilize one of two things to survive—stealth or speed. Both on land and beneath the sea, those who master either evasion or capture through these methods will thrive, living to reproduce and achieve the unspoken directive of their species. While stealth—through camouflage or evasion—is common, perhaps the most thrilling feature of many of the animals we find in the ocean are the fantastic speeds that can not only be achieved, but often maintained for long periods of time.Speed represents a tremendous expenditure, an investment of energy that must be replenished via consumed calories. Therefore, any observer should marvel not only at the existence of this trait, but also at the bounty of an ecosystem and the ability of individuals to draw their needs from that system. Their existence is a reflection of the fantastic diversity and abundance of our oceans. Here are ten of the fastest aquatic animals—both predator and prey.

动物世界里，不管是捕食者还是被捕食者，暗袭和速度是它们赖以生存的两大法宝。许多陆地和海洋生物正是通过这两项技能得以繁衍成长，维持在自然界中的生存地位。对于暗袭，大多数动物拥有独特的保护色和逃遁技巧，以此捕食或躲避天敌。然而，在海洋世界，失去遮蔽物和光线，速度才是生存王道。许多海洋生物爆发力惊人，不仅可以很快达到超高时速，更为赞叹的是凭借其惊人耐力能游行数小时。长时间竞速意味着巨大的体能消耗，需要通过摄入大量卡路里补充体力。因此，人们不仅会对这一特点感到惊奇，更会对它们身处生物系统底部却能以个体能力获得所需而惊叹不已。它们的存在就是海洋多样性及丰富性的最好体现。

Most kids like animals. Girls like cats, and boys like dogs. However, my favorite animal is the horse.

The horses are strong, not like the tame cats or puppy dogs. They look wild and hard to get close. Yet, they will be very timid and friendly after they get to know you. Horses remember the way home. They are also faithful to their masters. They even understand what you are trying to tell them. Ive heard many stories about how a horse saved his masters life. Thats also the reason why I love horses. They never betray you.

大多数孩子喜欢动物。女孩喜欢猫,和男孩喜欢狗。然而,我最喜欢的动物是马。

马是强大的,不像猫或狗温顺的小狗。他们看起来野生和难以接近。然而,他们会很胆小,友好在他们了解你。马记得回家的路。他们也对他们的主人忠心耿耿。他们甚至理解您想要告诉他们。我听说过很多故事一匹马救了他的主人的生活。这也是为什么我爱马。他们从不背叛你。

昨天放学时，天气非常炎热，我下楼没看见爷爷，就借同学手机打了个电话，然后我等了几分钟，爷爷就来了。

我上了车一边与爷爷闲聊，一边看着路边的风景。

突然我看到公路上有一个毛茸茸的小东西，是老鼠吗?怎么可能，怎么可能有这么大的老鼠，我又仔细看了看，这小东西正摇着它那蓬松的大尾巴，呀!是松鼠!太神奇了，居然在大马路上看见了松鼠。它好像要过马路似的左顾右盼的，好像不怕人，我们电瓶车走过，也没有引起它的恐慌。这时一辆路虎朝它飞驰而来，我心里一阵担忧，心跳顿时加快，仿佛有什么大事情要发生似的。一瞬间这辆路虎飞快超过我们，也穿过了这只松鼠，一声清脆的咔嚓声传入我的耳膜，是那样的惊天动地，我看着松鼠在半空中翻了几圈又啪的一声掉在路上，就一动也不动，一点生息也没有了。顿时一种莫名的悲伤涌上了我的心头。为一个鲜活的生命逝去而痛心。

也许这个司机是无意的，没有看见松鼠。也许这只松鼠太相信人类了，认为大家都喜欢它，不会伤害它。可以惨剧确确实实在我眼前发生了，难道不能引起我们思考吗?

在我国青藏高原可可西里这个无人区里生活着许多藏羚羊，在修建天路时怕火车影响藏羚羊的迁徙，设计者们想出了在那里架设铁路桥，这样火车在上面过，藏羚羊从下面迁徙，人与自然在这里完美可以结合。这是保护稀有动物的极好例子啊!

在澳大利亚生活着许许多多的动物，动物在马路上走对于这里的人们不足为奇，司机们开车遇到动物还要主动给它们让路。这在当地是人们自觉的行为，体现了他们的爱心，所以在澳洲这块土地上才会有那么多的动物与人和睦相处。他们的行为难道不值得我们仿效吗?

现在的环境越来越好，动物朋友们会随时和我们邂逅。对于那些不期而遇的朋友，我们除了惊喜，当然还要注意保护它们。我们司机朋友在路上，不仅要避让行人，也要避保护它们，这也是我们社会文明社会进步的表现。

我们的身边，经常看到伤害动物的行为，那些残忍血腥的行为让我们沉痛不已。保护动物，人人有责，希望每个人都能够做到，还动物们一个幸福和谐的家园，不要让人类成为它们心里的噩梦。

从前，有一个一年级的小学生小明，他的父亲天天到外面去打猎，没时间管他的学习。因此，他的成绩一直都不好。每天晚上，他的父亲都会捕来几只动物。他的父亲这样残杀动物，小明很伤心。“爸爸，不要再杀动物了，您知道杀动物是一件多么严重的事吗？这样会破坏生物链的，到头来，受损的还是我们呀！”小明说。他的爸爸严厉的回答说“你这么小懂什么？有时间就好好弄弄你的学习成绩吧！如果不打猎，靠什么吃饭？怎么供你上学？”小明说“那我好好学习，每次都得奖学金，你是不是就不打猎了？”“对，只要你的奖学金，我就不打猎”从此，小明就天天都努力学习。果然，在初中的时候学校答应只要他考试得第一名的时候就会给他奖学金。他的父亲也信守诺言，再也不打猎了。

就连一个一年级的小学生都懂的道理，难道那么多的猎人就想不清吗？你们有没有想过，假如你是一只动物，人类无缘无故的就把你杀了，你会愿意吗？肯定是千万个不愿意。俗话说得好“己所不欲，勿施于人。”你自己都不愿意，那动物们会愿意吗？就因为捕猎，现在都有多少种动物灭绝了，你们知道吗？已经800种了，这个数字看起来是不大，但是把每种动物的数量加起来，你们知道是多少吗？你们算过吗？破坏生物链，对人类一点好处都没有。

动物是大自然留给人类的无价之宝，所有的动物都是人类的好朋友，为什么就不能和睦的相处在同一个家园里呢？他们的生存与我们的生存，有着密切的关系。

保护动物，人人有责，这不是一句口号，而应该是一种行动。让我们一起保护动物，不要让它们再受到伤害了！

Like tangible cultural heritages such as the Great Wall and the Forbidden

City, intangible cultural heritages like Peking Opera and

Confucius-commemorating rituals are equally crucial. We should make our utmost

efforts to preserve intangible heritages because, without their physical form of

existence, they are in greater risk of extinction.

According to UNESCO’s Convention for the Safeguarding of Intangible

Cultural Heritage (2003), all forms of social customs and habits, folklore,

performing arts, rituals, oral traditions, festivals, traditional crafts and

various knowledge and practices about nature and universe can be classified as

intangible cultural heritages. As a country consisting of a great diversity of

ethnic groups and with time-honored history and civilization, China abounds in

intangible cultural heritages. Cultural heritages connect modern people with the

historical past, allowing them to acquire a cultural and historical identity.

Without cultural heritages, we would be rendered absolutely rootless and we

would find it hard to cope with challenges at present and in the future.

However, the modernization process poses mounting threats to intangible

heritages. Many people have a blind faith in the latest electronic devices. It

is also pathetic to see elderly people in possession of such legacies pass away

without transmitting them to the younger generation. Faced with those

challenges, we should both preserve and renovate our ancestral heritages so that

we can help contribute to the cultural diversity of the world and return to our

spiritual homeland in this age of impersonal science and technology.

Humans have only one earth. He is the cradle of life, is the homeland of all mankind. However, the environmental pollution and ecological destruction have on human social and economic development and peoples normal life constitutes the real threat. Take good care of the environment, advocate civilization, is the human moral and responsibility.

We want to clean the earth, eager to healthy earth, eager to the homes of environmental protection, eager to green, health, community health... Let us use love to pay attention to changes in the environment, with passion to spread the idea of environmental protection, with actions to shoulder the important task of environmental protection. Starts from me, start from now, intravenous drip minor matter, starts from the side the environmental commitment into action.

Remember, protect the earth, is to protect ourselves.

人类只有一个地球。他是生命的摇篮，是人类共有的家园。然而，环境污染与生态破坏已经对人类的社会经济发展和人们的正常生活构成了现实威胁。爱护环境，崇尚文明，无疑是人类自身的道义和责任。

我们渴望干净的地球，渴望健康的地球，渴望环保的家园，渴望绿色，健康，卫生的社区……让我们用爱心去关注环境的变化，用热情去传播环保的观念，用行动肩负起环保的重任。从我做起，从现在做起，从身边的点滴小事做起，把环保承诺变为实际行动。

记住，保护地球，就是保护我们自己。

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。

今天，我到了外婆家里玩。到了下午邻居把他们家里养的两只羊放出来，放到田里吃草。我就和田田和她的弟弟一起去拔嫩的草，田田用镰刀割我和她的弟弟用手拔。我们到处拔草，我们拔了小小一篮子。我们回来的时候羊在吃树叶。我们马上跑过去把手里的草给了羊吃，两只羊马上向我们冲来我左手拿草给它们吃。它们在吃草的时候，我摸了摸他们的羊角很硬还有点热。我们把草喂完了以后，一只小点的羊就跑到对面的小树林里去了。另外一只也跑过去了在小树下吃树叶。

我看到了一只大点的用头上的角在树上顶来顶去。我想因为那只羊的角长长了痒，所以顶树。就像小孩子长出牙要痒一样。
