When you are passing the trash can, you can pick up the cola bottles beside? When you see someone scribble carving in the tree, you will not to stop at the meeting? When you are in the stalls to eat small, can you come up with their own spare chopsticks instead of disposable chopsticks?

Now, a lot of people cut down a tree in the forest, the trees to make chopsticks, chairs, tables, etc., can cause soil erosion, flood will often and bring us unfortunately. We should act to prevent them.

Even if the pockets dont money, we should also have the mindset of environmental protection, environmental protection bag.

We cant learn the somebody else, be sure to write "environmental protection" moment in their heart, and reflect in action, starts from me, starts from the minor matter.

环境是目前所有人关注的话题，也是所有人关注的一个热点。好的环境，有利于我们健康成长、心情舒畅，无论学习和生活都特别舒服，所有人都希望生活在一个好的环境下。因此，保护环境，人人有责。

当你路过垃圾桶的时候，你会不会捡起旁边的可乐瓶?当你看见有人在树上乱刻乱画，你会不会上前去阻止?当你在小摊吃小面的时候，你会拿出自己的备用筷子而不用一次性筷子呢?

现在，很多人在森林里砍树，把树木做成筷子、椅子、桌子等等，就会造成水土流失，洪水也会经常冲来，带给我们不幸的危险。我们应该立刻行动，阻止他们。

在超市里，我们会看到很多人还用钱来买口袋，虽然一个口袋只要2角钱，但是保护环境是每一个公民的责任和义务。即使口袋不要钱，我们也应抱有保护环境的心态，用环保口袋。

在上学的路上，我们看见有人在路上乱扔垃圾，乱吐口痰，我们应该教给他方法：吐在纸巾里，然后扔进垃圾桶。我们更不能学人家，一定要把“保护环境”时刻记在心里，并体现在行动中，从我做起，从小事做起。

我相信，通过大家的努力，环境会变得越来越好，地球“妈妈”也会变得更加美丽。

我们都知道动物们是我们人类的朋友，它们和我们共同生活在地球上面，跟我们享受一样的资源，但是现在社会上会有很多虐待动物和宰杀动物的行为，这些行为都是很不好的，我们要懂得保护动物，让他们和我们一起生活在美丽的地球上。

最近新闻上总是会有一些虐待动物的新闻，比如说一个男就把自己怀孕的小猫关在了笼子里，活生生的用热水把它烫死了，我觉得这样都是非常没有人性的行为，既然领养了这只动物，就应该好好的对待他，对她负责，而不是用这样的方式来折磨她，我觉得这样是很没有人性且没有良心的，这种行为也应该受到全社会的谴责。然而这个社会上面这个男人的做法并不是隔离甚至在生活上面有很多人会有这样的行为，他们虽然领养了动物，但是却没有好好的对待动物，反而去折磨他们，虐待他们，让他们受到了不好的待遇，又会受到了摧残，还有一些人会对不是自己的宠物的动物虐待和折磨，比如说有的生气的人就会把流浪猫和流浪狗作为出气筒给他们身上发泄，对待他们殴打他们这些猫猫狗狗就会受伤，甚至会被殴打致死，都是非常残忍的。

小动物们都是我们的好朋友，他们和我们共同生活在地球家园上面是我们的陪伴，所以我们和动物之间应该和睦的相处，特别是现在有一些动物已经濒临灭绝了，被设立成了国家的保护动物，但是有一些人执法犯法，野外去捕杀这些保护动物，违背了国家的法律也是没有人性的，这些行为都是不对的，我们每个人都要增强保护动物的意识，让我们和小动物们和谐相处，共同生活，

在美丽的地球家园上。

Today, we read a lot about the passage to protect the environment. I recall ever happened in my side.

Remember last years summer vacation, my father and I went for a walk EHu edge, a way, Im kind of shouted thirsty, so my father on the side of the road store bought me a Popsicle. I ate and go, soon finished eating, carelessly threw the ice sticks into EHu. Dad saw, reminded me immediately; "Coco, cant litter oh! If everyone like you to throw garbage in the lake, the beautiful EHu lake becomes waste." Im ashamed of say: "know, next time I must not litter." Dad smiled and stroked my head and said: "the earth is our home, we should protect it, cherish it, let the sky bluer, the water cleaner, the grass is greener." I naughty to say: "oh, that is, everybody has said, the city is my home, clean environment depends on everybody. I understand." From then on, I no longer throw garbage.

I want to take care of the environment is closely related to everyone, so lets start from everyone!

今天，我们读了很多关于保护环境的小短文。我想起曾经在我身边发生的事情。

记得是去年的暑假，我和爸爸一起去鹅湖边散步，走了一段路，我就一个劲的喊口渴，于是，爸爸就在路边的小店给我买了根冰棍。我边吃边走，一会儿就吃完了，随手把冰棍棒往鹅湖里一扔。爸爸看见了，马上提醒我说;“可可，不能乱扔垃圾噢!如果每个人都像你一样往湖里扔垃圾，这美丽的鹅湖不就变成了垃圾湖了。”我羞愧的说：“知道了，我下次一定不乱扔垃圾。”爸爸微笑着抚摸我的头说：“地球也是我们的家，我们应该保护它，爱护它，让天更蓝，水更清，草更绿。”我调皮的说：“噢，那就是大家一直说的，城市是我家，环境清洁靠大家。我明白了。”让从那以后，我再也不乱扔垃圾了。

我想爱护环境与每个人息息相关，所以要从每个人做起!

关于英语环境保护作文结尾要如何写呢？下面是小编整理的英语环境保护作文结尾事例，希望能给大家带来帮助。

文章结尾的作用是概括全文内容，进一步强调或肯定文章的中心思想，使文章意义表达得更加深刻。

文章结尾的形式也是多种多样的，常见的有以下几种：

1、首尾呼应，画龙点睛

在文章的结尾，把含义较深的话放在末尾，以点明主题，深化主题，起到画龙点睛的效果。如“I Cannot Forget Her” (我忘不了她)的结尾：

After her death, I felt as if something were missing in my life. I was sad over her passing away, but I knew she would not have had any regrets at having given her life for the benefit of the people.

2、重复主题句

结尾回到文章开头阐明的中心思想或主题句上，达到强调的效果。如“I Love My Home Town”(我爱家乡)的结尾：

I love my home town, and I love its people. They too have changed. They are going all out to do more for the good of our motherland.

3、自然结尾

随着文章的结束，文章自然而然地结尾。如“Fishing”(钓鱼)的结尾：

I caught as many as twenty fish in two hours, but my brother caught many more. Tired from fishing, we lay down on the river bank, bathing in the sun. We returned home very late.

4、含蓄性的结尾

用比喻或含蓄的手法不直接点明作者的看法，而是让读者自己去领会和思考。如“A Day of Harvesting”(收割的日子)的结尾：

Evening came before we realized it. We put down our sickles and looked at each other. Our clothes were wet with sweat, but on every face there was a smile.

5、用反问结尾

虽然形式是问句，但意义却是肯定的，并具有特别的强调作用，引起读者深思。如“Should We Learn to Do Housework?”(我们要不要学做家务？) 的结尾。

Everyone should learn to do housework. Don’t you agree, boys and girls?

6、指明方向，激励读者

结尾表示对将来的展望，或期待读者投入行动。如“Let’s Go in for Sports”(让我们参加体育运动)的结尾：

As we have said above, sports can be of great value. They not only make people live happily but also help people to learn virtues and do their work bettter. A sound mind is in a sound body. Let’s go in for sports.

文章的结尾没有一定的模式，可以根据表达主题的需要灵活创造。一般的习惯是，一些记叙文和描写文经常采用自然结尾的方法；但说理性和逻辑性较强的说明文和议论文则往往都有结束语，以便使文章首尾呼应，结构完整。

秋风席卷着落叶四处飘洒，落日的余晖染红了树木茂密的尕拉布森林，不远处，一名猎人和一名伐木工正朝着森林走来。

猎人的名字叫巴洛，已近年近古稀，他是尕拉布村庄最优秀的猎人，他熟悉一切动物的行踪与习性，每次打猎无一不带回猎物，他打猎都是心狠手辣不管是可怜地流泪的小鹿甚至是向他低头求饶的大熊，没有一个被他放过，都一一惨死在他的枪下，他这次是帮伐木工巴厘一起去森林伐木的，以保证巴厘的安全。

巴厘领着巴洛来到自己认为拥有最最上等木材的一片树林，信心满满地对巴洛说：“我每次都到这里伐木。这里的树可是最最上等的，如果我们都砍了去卖，一定能买个好价钱！”瞧瞧巴洛，他不满地皱起了眉头：“不，我们不能在这里伐木！”巴厘不解地问：“为什么？”巴洛慢慢地回答：“这里是狼群的领地，我们在这里伐木万一遇上了狼群就不好干了！”“不可能！”巴厘铿锵有力地说：“我在这里伐木了无数次，都没有遇到狼群！”“啧，那是侥幸！”巴洛说：“你没看到树上的狼毛吗？”“哼，就算这里真的有狼群，”巴厘满不在乎，拍拍巴洛腰上的：“你开一枪，就算不打死一只狼也会把它们吓跑的，啧，我最不愿意亲近这些脏兮兮的奸诈的狼们了，你看狼的成语，狼狈为奸，狼心狗肺，有哪个是好的？”“也是。”

“咔咔咔咔咔咔……”伐木的声音震耳欲聋，吓跑了鸟儿，吓跑了走兽，“咔咔咔咔咔咔……嗷呜！”巴厘砍下第一棵树的同时，从旁边的石洞里跳出了一只白母狼，它愤怒地嗥叫着，似乎在说：“人类，你们竟然私闯我们的领地！”“啧，你看，一只母狼不出来了？还是白的！”巴洛指着母狼，对巴厘说。巴厘望着白母狼，垂涎三尺：“啧，白的，你快打死它，这皮，可能买个好价钱！”“好嘞！”

没想到的是，随着白母狼的出现，巴洛和巴厘的视线里又出现了一只小白狼，黏糊糊地跟在白母狼后面。“啧，这是一对母子喏，两只都是白的，价钱一定与五匹小牛犊不相上下！”巴厘的口水“飞流直下三千尺”。

“好嘞！”巴洛连忙拿起和葫芦，往里灌火药铅巴，“呦！”小白狼见了，四处溃逃，巴洛找准时机“咻！”散弹朝着小白狼射去，小白狼嗥叫一声，拼命逃跑，眼看散弹就要撞上了，却……

白母狼突然飞奔上前，挡住了小狼！散弹射中了它的脑袋，顿时脑浆四溢，白母狼的脑袋开了花！

巴洛和巴厘都被白母狼这样的举动给惊呆了，小白狼呜咽着，好想知道自己的妈妈再也起不来了，趴在白母狼的身上，用怨恨的眼光望着猎人和伐木工，那眼神不仅让两个人都打了一个冷颤，小白狼好像瞬间成熟了许多，摆出一副大公狼输死拼搏的样子，突然，白母狼诈尸般地跳了起来，一双眼睛像点燃了的火炬，它在警告巴洛和巴厘，也在警告所有不遵守自然平衡的人类：你们既然不愿意亲近我们，那么我们也将不愿意亲近你们，你们随便杀我们狼吧，随便杀所有的动物吧，当动物因为你们的灭绝使得食物链缺少了重要的一环，你们的末日就要到了，你们的末日，就是我们的复仇之日！白母狼着火般的眼神如同流星一现，慢慢地熄灭了，它又倒下了，这次是真的起不来了，小白狼仿佛瞬间拥有了很大的力气，它拖着妈妈的遗体，走向残阳。

夕阳西下，森林的鸟儿正为白母狼唱着一首悲哀的葬歌，也正在告诉人类：我们不是好惹的。

在四野飘香的花丛中，我和蝶儿一起嬉戏、欢笑;在郁郁葱葱的森林里，我与小鸟一起追逐、歌唱;清晨，我迈着轻盈的步履去原野上踏青，雾霭缭绕着、白纱般的柔柔地漂浮在空中。吮吸着花草的芳香， 欣享着阳光的沐浴，我被陶醉在这如痴如醉的梦幻里;夜晚，我坐在稻谷飘香的农家小院里，仰望着璀璨的星空，聆听着蝉鸣嘹响，蛙声如潮，仿佛置身于一个童话般的王国。

In the fields the fragrance of flowers, butterflies, and I play together in laughter; a wild profusion of vegetation in the forest, I chase, with birds singing; early in the morning, I walked with light steps to the fields on the outing, mist shrouded with white veil, gently floating in the air. At the scent of flowers and plants, we enjoy the sun bath, I was intoxicated in the dream of the night, delude one to folly; I sat in the fragrance of rice farmers in a small courtyard, looking up at the bright sky, listening to the sound of cicadas Liao ring, frog sound waves, like being in a fairy tale kingdom.

今天，我读了《白耗牛》一书，受益匪浅。

《白耗牛》讲述的是这样一个故事：在一个牧场里，丢失了一只珍贵的耗牛。这时，，个叫贡嘎的学生，要为玛尔吉阿婆找回这只白耗牛。他翻山越岭终于从一个守林人那里了解到白耗牛被偷到了长岭山的牧场，还得知牛贩子康劳要杀白耗牛。他只身勇闯虎穴，终于从康劳的手里抢回了白耗牛。

读了这个故事，我想：“连个学生都能这样为国家保护珍贵动物，而现在很多人却随便捕杀野生动物，破坏环境，使动物们生存受到了威胁。”

我曾在电视上看到这样组镜头：非洲草原土，横七竖八地躺着被割去象牙的非洲象，周围一片鲜血；一条肮脏的冒着白泡的河流中，漂着一条一条死鱼；还有被关在笼中的猴子……

记得有一次，爸爸带我们到饭店吃饭，我忽然看见了饭店一角关着两只穿山、甲，鱼池里还有中华鳃，这些可是国家保护动物啊！怎么能被吃掉呢？

这不禁让我回想起了我看过的一部纪实影片：一只活泼可爱的小猴子被关到了一个特别的笼子里，只露出一个脑盖来，侍者拿出锤子对着脑盖敲了几下，小猴的脑盖便开了，而那些可恶的客人竟然用热水烫过的勺子舀着猴脑吃。小猴在那里大声惨叫着……

这是为什么？人类本应与自然和谐共处，但有些人却为了金钱，不择手段，屠杀手无寸铁的动物。从此，大自然的生态平衡被破坏了。

地球已经千疮百孔了，如果我们人人都像贡嘎一样，那么很多珍稀的动物也不会灭绝，动物们也不会向人们苦苦哀求了！

朋友们，快清醒吧，动物是人类的朋友！我要大声呼吁:“保护动物，人人有责，让我们共同保护我们的家园吧！"

广大市民朋友们：

大熊猫是世界上最珍贵的动物之一，主要分布在我国的四川、甘肃、陕西省的个别崇山峻岭地区，数量十分稀少，属于国家一类保护动物，称为“国宝”。

它不但被世界野生动物协会选为会标，而且还常常担负“和平大使”的任务，带着中国人民的友谊，远渡重洋，到国外攀亲结友，深受各国人民的欢迎。大熊猫身体胖软，头圆颈粗，耳小尾短，四肢粗壮，身长约1.5米，肩高60-70厘米左右，体重可达100-180千克。特别是那一对八字形黑眼圈，犹如戴着一副墨镜，非常惹人喜爱。 大熊猫的祖先是食肉动物，现在却偏爱吃素，主要以吃箭竹为生。

一只成年的大熊猫每天要吃20千克左右的鲜竹。有时，它也会开一次“荤”，捕抓箭竹林里的竹鼠美餐一顿，甚至大摇大摆闯入居民住宅，偷吃食物。大熊猫性情孤僻，喜欢独居，昼伏夜出，没有固定的居住地点，常常随季节的变化而搬家。春天一般待在海拔3000米以上的高山竹林里，夏天迁到竹枝鲜嫩的阴坡处，秋天搬到2500米左右的温暖的向阳山坡上，准备度过漫长的冬天。

每年的四五月份是大熊猫的繁殖季节，雄、雌大熊猫难得同居在一起。但5月一过，便又各奔东西。雌性大熊猫怀孕4-5个月左右，就急着寻找树洞或石穴作为“产房”，它每胎产1-2仔。刚生下的幼仔重量只有150克左右，相当于妈妈体重的1‰。

可是，一个月后体重可达2千克，3个月就能长到五六千克。熊猫妈妈常把小熊猫搂在怀中，轻轻抚摸，外出时也把它衔在嘴里，或用背驮着，亲亲热热，形影不离。等到小熊猫五六个月大时，妈妈就开始教它爬树、游泳、洗澡和剥食竹子等本领。两年后，小熊猫才离开母亲，开始独立的生活。大熊猫的寿命一般为20-30年。 大熊猫的家族非常古老。

大约在一百万年前，它们遍布我国的陕西、山西和北京等地区，在云南、四川、浙江、福建、台湾等省也有它们的踪迹，现在留下来的数量很少，成为科学家研究生物进化的珍贵的“活化石”。 迄今为止，全世界200多个国家和地区都没有几乎濒临绝迹的大熊猫，只有在我国的四川、陕西、甘肃部份地区的深山老林中才能找到它们的身影。

目前全世界的大熊猫总数仅1000只以下，而且数量在不断减少。 根据科学统计有78％的雌性大熊猫不孕，有90％的雄性大熊猫不育，这就给大熊猫的繁殖带来了许多困难。 在动物学上，大熊猫属食肉目。据考证，大熊猫的古代名称有貘、白豹、虞等。在200多万年前的更生世早期到100万年前的更生世中晚期，大熊猫已经广布于我国南半部，组成了大熊猫----剑齿象动物群；今天该动物群的许多种已经绝灭，而大熊猫却一直活下来，所以大熊猫有“活化石”之称。

My home have a clever dog flow li, it has a beautiful name - the ball ball.

Ball ball body white as snow, two big eyes, nose and smooth detour, tail short, chopped far look like a small ball.

This is my familys good sleep and greedy ball ball, do you like it?

我家有一只聪明怜俐的小狗，它有一个好听的名字—球球。

球球全身毛白如雪，铜铃大眼，鼻子滑漉漉的，尾巴短短的，远看就像一个小茸球。

它特别喜欢睡觉。有一次，我去洗澡，它在客厅东走走，西逛逛，实在无聊了便走到床头柜下，抻了个懒腰，肚皮朝上，悠然自得的躺在地上。小脑袋向左面歪着，两只小爪紧紧的抱在一起，很陶醉的闭上眼睛睡着了。等我洗完澡，正想找它玩的时候，看到它已经呼呼大睡了。

它不但爱睡觉，还很贪吃。记得有一次，我们吃着香喷喷的排骨，球球看见了，馋得直流口水，看到它的样子，我真的不忍心，只好向地上抛了一块骨头，小狗跳了起来，迅速地叼住了骨头，爬到了床底下，狼吞虎咽地吃了起来，吃得津津有味。

这就是我们家贪吃好睡的球球，你们喜欢它吗?

I have a dog ,her name is Happy,I very love her.Her is clever and friendly.She loves to walk with me.She always plays with my grandmother,so I think is smart.I also like talking to her,she can understand every words which are said by me.

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。

Animals are friends of human beings, everybody is responsible for animal protection, we should take good care of them. Because, there are a lot of insects are beneficial to human. For example: the bee, it is industrious, very early in the morning to go out honey, again and again. In the dark, after the bite honey, non-stop to adopt to carry on the processing of honey. The appearance of the bees and ordinary, life is very short, only about 3 months, Can it all his life not rest, work diligently, and them nothing in humans, but for people to make sweet and delicious, nutritious, honey can cure sickness.

And the frog, the frog is covered with green clothes, two big eyes, like two stars glittering and translucent and transparent glass ball, it hid in the field, only eat insects, protect crops. Two a push with its back when it catch insects, a jump, nimbly hind legs up, jump up high, long tongue out, like a vacuum cleaner quickly eat insects to the stomach. But we humans can use them as delicious food on the table.

There are many lovely animals, my favorite is the giant panda. The giant panda is our precious animals, my mother told me that the giant panda is a national treasure of our country! Long giant pandas are cute, chubby, plump, start to counteract a, particularly funny. Its head and body are white, only the rim of the eye, ear, and the shoulder is dark brown. Especially that a pair of black rim of the eye, long in white face, like wearing a pair of sunglasses, plus the clumsiness and start to look in all directions, looks like a little gentleman.

You look! They are adorable, they are our humans good friends, how are we going to have the heart to hurt them?

动物是人类的朋友，保护动物人人有责，我们应该爱护它们。因为，有很多昆虫都对人类有益。比如说：蜜蜂，它很勤劳，每天早上很早就出去采蜜，一次又一次。到了天黑，吃几口蜜糖后，就马不停蹄地对采来的蜜进行加工。蜜蜂的外形并不起眼，生命也很短暂，只有3个月左右;可它一生都不休息，勤勤恳恳地工作，它们对人类毫无所求，却为人们酿造了甘甜可口、营养丰富、可医治病痛的蜂蜜。

还有青蛙，青蛙披着碧绿的衣裳，两只大眼睛，像两颗晶莹透明的玻璃球，它藏在田里，专吃害虫，保护庄稼。它捉害虫的时候两条后腿一蹬，一纵身，敏捷地将后腿一蜷，跳起老高，长长的舌头一伸，就像一个吸尘器一样转眼就把害虫吃到肚子里去了。可是，我们人类却把它们当成美味佳肴摆在餐桌上。

还有许多可爱的动物，我最喜欢的是大熊猫。大熊猫是我国珍贵的动物，妈妈告诉我大熊猫还是我们国家的国宝呢!大熊猫长的很可爱，胖乎乎、圆滚滚的，走起路来一摇一晃的，特别逗人。它的头部和身体都是白色的，只有眼圈、耳朵和肩部是黑褐色的。特别是那一对黑黑的眼圈，长在白白的脸上，像是戴着一副墨镜，加上那笨拙的动作和走起路来东张西望的神情，显得像个小绅士。

你瞧!它们多么可爱，它们是我们人类的好朋友，我们怎么忍心伤害它们呢?

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。

It seems we are living in the conflict between modern and traditional cultures every day. Hearing the blaring of horns the moment you step out of your house, seeing the so called "pop" the moment you open your eyes, you cant help thinking, "Will the traditional culture be gradually lost?"

Many people believe so. They may put right in front of you all the evidences they can dig out. They may argue that people are rushing to restaurants instead of cooking at home, listening to pop music but not traditional, wearing in a way people couldnt imagine ten years ago. Modern people like the air of freedom, not to be restrained by traditions. They offer this long list, only trying to confirm that this world is full of fashion,competition and temptation and the traditional culture is fading

and will be lost at last.

Though we are now living in a world in which undeclared aggression, war, hypocrisy, chicanery, anarchy are part of our daily life. Though this is a skeptical age, and our faith has weakened, our confidence in some aspects of the traditional culture should and would never be lost.

Wouldnt you agree that our traditional culture is always credited with modesty, politeness and respectfulness, which have always been treasured for more than five thousand years?Even in this modern world, people still admire those with good manners, those who are polite to others or respectful to old people.

Wouldnt you agree that our Chinese traditional music is beautiful and artistic and our Chinese tea culture is always an appealing treasure to people around the world?

So there may just be some changes in our lifestyle or our attitudes towards life, but little change occurs to some fundamental aspects of our traditional culture that people still treasure in heart.

The national level protection animal giant panda, have you ever seen giant pandas? Come and see! The following is a lovely giant panda, see how delicious it eats! The smile is so lovely.

You said, why so little panda, it is because of the destruction of the human disorderly cut down trees, dont take care of flowers and plants, destruction of the atmosphere, to lead to a drop in the panda, so we have to take care of the panda, the giant panda is herbivorous animals know, likes eating bamboo, but not as the giant pandas in the zoo keepers to feed their fruit. Wild panda anecdotes: in recent years, scientists found hidden cameras, male wild pandas left a breath marks on a tree, will lift a leg, like a male dog, and then the urine to the heights of the tree and. The higher the urine, the higher the social status of the male giant panda. Good play! Just like a dog! This is fun. Ax mountain in north of the city, we established a lush bamboo sea and the forest, form different from downtown chengdu "microclimate", in 1987, formally completed, now has developed into a specialized in endangered wildlife research and breeding, protection of education and education tourism, a nonprofit organization.

Do you know how pandas digest bamboo? Researchers have found that the giant pandas digestive tract is short and simple, and there is no such thing as a long, plant-eating animal with a thin gut and a complex stomach or a developed cecum. In addition, the giant pandas genome sequences announced in 2009, after they found the giant panda to the lack of some help in the digestive tract herbivores digest cellulose and hemicellulose (they are the main components of the fibrous plant diet) enzymes. This is confusing for researchers, and how does the lack of these necessary conditions digest bamboo?

Researchers use of gene sequencing technology, analysis of more than 5000 ribosomal RNA sequences, eventually in the giant panda, found a variety of digestive tract bacteria and some microbes are very similar to grazing animals. These help animals digest cellulose in their bodies, and seven of them are unique to the pandas digestive tract. Bye bye!

The earth mother as the cradle of life, human like a spoiled child of the earth. She give us everything we need for life leave her, we will get nothing. Beautiful living environment is the basis of which we live, but now, our environmental protection consciousness is more and more weak. Though, we all know that protect the environment, but not the property of the consciousness of earth, destroy the originally beautiful environment; In fact, in life, as long as pay attention, everywhere can be environmental protection.

In those restaurants everywhere can see around us, the boss in order to achieve "health" standard, and unconsciously extensive use of wooden chopsticks that were made from wood; Cost is huge, hits the verdant trees with bangs fall, only the birds were forced to leave, a group of a group of lovely animals homeless again, but as they didnt see, originally natural ecological environment destroyed by them, just like that. Not only did not have the forest, and animals are not spared. Recently, some cantonese put smart cute little monkeys alive opened the brain had his head down, they looked at each cute little monkey innocent dead, but still, this is what a horrible thing!

We as the master of the earth, if you dont cherish everything now, that this beautiful environment will leave us early. At that time, we will face catastrophe, the earth will be scarred, and hurt; So we should do owners should do, well protect our survival environment, do not deliberately to destroy, remember: to protect the environment, is to protect the future of mankind.

地球母亲就像是生命的摇篮，人类就像是地球的骄子。她，给予了我们生活所需要的一切离开她，我们就一无所获。美好的生存环境是我们赖以生活的基础，可是现在，我们保护环境的意识却越来越淡薄了。虽然，大家都知道保护环境，但却不自觉的掠夺地球的财产，破坏原本美丽的环境;其实，在生活中，只要留心，处处都能环保。

在我们周围的那些餐馆中随处可以看到，老板为了达到“卫生”的标准，而不自觉的大量使用那些用树木做出的木质筷子;为此付出的代价是巨大的，一棵棵青翠的树木随着巨响而轰然倒下，一只只鸟儿被迫离开，一群又一群可爱的动物无家可归，可他们却当作没有看到，原本自然的生态环境就这样被他们破坏。不仅森林没有了，而动物也是不放过。最近，一些广东人竟然把机灵可爱的小猴子活活的把头打开把脑子吃了下去，他们看着一只只可爱的小猴子无辜的死去，却还是无动于衷，这是多么令人发指的事呀!

我们身为地球的主人，如果不珍惜现在的一切，那这美好的环境一定会早早的离开我们。到时候，我们会面临灾难，地球也会伤痕累累，而受到伤害;所以我们应该做到主人应该做的事，好好的保护我们生存的环境，不要蓄意的去破坏，要记住：保护坏境，就是保护将来的人类。

对人有益的动物有很多，例如有蜻蜓、青蛙和小燕子等等。

我们先说蜻蜓吧，它是益虫，它对人的益处可多了。它生活在小池子旁边，捕捉害虫。有些人，捉蜻蜓，捕蜻蜓，捉住后到处卖。我们应给立一个保护蜻蜓法，如果他们再敢捉蜻蜓，捕蜻蜓，就是知法犯法，交给警察叔叔处理。

青蛙也不例外，它也是捕捉害虫的能手，不过，它生活在庄稼附近的池子旁边，有时候，它也到庄稼地，旁边捕捉害虫，人们都称它保护庄稼的好帮手。有的小朋友，到池子旁边，捕捉青蛙，回家后，吃青蛙。我们应该在池子旁边树一个牌子，上面写着“保护青蛙，人人有责”，这样就不会有人捕捉青蛙了。

小燕子也是捕捉害虫的一类，它生活在大树的鸟巢里，它在天空捕捉害虫。有些人，用枪把小燕子射下来，回家吃了，或者卖了。我们应给设一个森林保护区，让小燕子和其它受保护的动物住进去，这样，既保护了小燕子，也保护了其它的动物。

如果没有这些有益动物，害虫就会增多。这样，连农药和灭害灵都不行了。我们应给共同保护动物。

Water is the source of life. Human can not do without water, animals, plants cannot survive without water. We every day to drink water, water, not only we need water, the fish in the water, the crops of the fields, the trees on the hill, and so on all need water. Some people may think so: water is to burn forever, love how how waste waste, this idea is wrong, we should change the idea.

I listen to mama said, in our city the creek, at the time of their small river on the bottom, they often catch fish in the river, catch shrimp, game play, but now is full of rubbish, into a dry river.

Water had a close relationship with each one of us, if there is no water, crops cant grow, we have no food to eat and vegetables, we wash hands, wash dishes, laundry every day... A moment also can not do without water. We cant live without water. Since the water effect, we should save water, form the good habit of saving water, do people go to close the tap, dont throw the rubbish into the river... Keep water clean.

For all of us have a good living environment, let us together hand in hand together, starts from me, start from now, sets up the idea of saving water, protecting water, take good care of water is to take care of ourselves.

In order to our better future, we all work together!

水是生命的源泉。人类离不开水，动物、植物也离不开水。我们每天要喝水、用水，不光我们需要水，水里的鱼儿、田里的庄稼、山上的树木等等都需要水。有的人可能这么想：水是永远用不完，爱怎么浪费就怎么浪费，这种想法是不对的，我们应该改变这种想法。

我听妈妈说，在我们城里的这条小河，在她们小的时候河里清澈见底，她们经常在河水里捉鱼、捉虾、游戏玩耍，可是到了现在却到处是垃圾，成了一条干枯的小河。

水与我们每一个人都关系密切，如果没有水，农作物就无法生长，我们就没有吃的粮食和蔬菜了，我们每天洗手、洗菜、洗衣…一刻也离不开水。如果没有水，我们就不能生存。既然水的作用那么大，我们就应该节约用水，从小养成节约用水的好习惯，做到人走关好水龙头、不把垃圾扔到河里…使水能够保持干净。

为了我们大家有一个良好的生活环境，让我们一起携手起来，从我做起，从现在做起，树立起节水、护水的观念，爱护水就是爱护我们自己。

为了我们美好的未来，我们大家一起努力吧!
