动物园里的动物用英语介绍精彩20篇

幼长臂猿躺在放有热水袋的棉被里；黑天鹅的“卧室”放上了取暖器；体积庞大的大象周围也烧起堆堆炭火……南宁市这两天温度骤降，预计气温会降到5°C—7°C。天冷了，人会想方设法取暖，可那些不会照顾自己的动物们如何“熬”过这个寒冬呢?记者顶着寒风，来到南宁市动物园去“看望”它们如何过冬。

动物园里怕冷的动物有长臂猿、黑叶猴、松鼠猴、大象、黑天鹅、鳄鱼、蛇、犀牛等，记者一一对它们进行了“拜访”。

引人观注的鳄鱼池没有了往日的喧闹。饲养鳄鱼的师傅说，鳄鱼嘴里有一层鹅黄色的膜，它能吸收大量的热量。而此时因为水里的温度比岸上温度略高，所以它们全部潜到水里找温暖去了。动物园在鳄鱼池边建有暖气房，往年气温降到7°C以下时，工作人员就想办法把半冬眠的鳄鱼一条条拉入室内保温。今年略有些改变，只是在早上和晚上抽取暖和的井水换掉鳄鱼池中冰冷的水，这样，鳄鱼就可以在水里安全过冬了。

最可怜的要数国家一类保护动物长臂猿了，它们最怕冷，两只出生不久的小长臂猿被妈妈抛弃了，冷得嗷嗷直叫。动物园为了救活这两只价值数万元人民币的长臂猿，决定人工喂养，而保暖工作也是无微不至的，像哺育婴儿一样。记者在长臂猿馆里看到，它们暖和的小床上面有厚厚的棉被，还有热水袋，两只小猿已度过了危险期，在房里蹦来蹦去。

大象因为体积庞大，比较难对它保暖，动物园只能在圈大象的栏杆外烧起了炭火给它们取暖，员工们轮流昼夜值班，为大象“烧火”。美丽的黑天鹅没有攻击性，只需在房里放上取暖器就可以了，记者看到它们正在优雅地梳理着羽毛。冬眠的蛇在暖气房里乐不思蜀，一改冬眠的习性，蠕动着身子寻找食物，并作些健身运动。笨重的犀牛住在动物园的仿真草房里，全身披着铠甲似的厚皮，“床”上垫上了可以保温的木板，特别厚。

而那些不怕冷的动物在这样的气温里过得尤为惬意，海狮、狮子、虎、豹等非常活跃。准备参加春节大汇演的海豹正在碧绿的水中强化训练，它们追逐着、打闹着不肯停下。以往这些不怕冷的动物一到天寒地冻时便偷着乐，现在这种“几家欢乐几家愁”的局面已不存在了，有动物园的精心照顾，所有的动物都能够把冬天当作春天过了。

The "Chong Yang Festival" is celebrated on the ninth day of the ninth lunar month, and it is as such known as the Double Ninth Festival.

Origins: The festival began as early as the Warring States Period (475 - 221 BC). According to the yin/yang dichotomy that forms a basis to the Chinese world view, yin represents the elements of darkness and yang represents life and brightness. The number nine is regarded as yang. The ninth day of the ninth month is a double yang day, hence the name "Chong Yang Festival". (Chong means "repeat" in Chinese.) The ninth month also heralds the approach of winter. It is a time when the living need warm clothing, and filial Chinese sons and daughters extended this to make the festival a time for providing winter clothes for their ancestors. The Double Ninth Festival, therefore, also became an occasion to visit the graves of dead family members. Clothes made of paper would then be burnt as offerings.

Climbing mountains: On the Double Ninth Festival, people customarily climb mountains, appreciate chrysanthemum flowers, drink chrysanthemum wine, and eat double-ninth cakes. The Double Ninth Festival is also the "Old Men Festival". Old people are especially meant to improve their health by taking part in the activities on the day of the festival.

Family get-togethers: The Double Ninth Festival is also a time for family get-togethers. It is an occasion to remember one‘s ancestors, the sacrifices they made and the hardships they underwent. Often, family outings are organised during which people search to renew their appreciation of nature and to reaffirm their love and concern for family members and close friends.

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。

Henan has a humid warm-temperate climate. Dry and windy in winter and spring, the province is hot and rainy in summer and bakes in strong sunlight during the autumn months. Rainfall averages about 600-1000 millimeters increasing from north to south, as does the annual temperature which increases from about 12.8C in the north to 15.5C in the south.

Henan province is considered the cradle of Chinese civilization due to its location on the Yellow River. This rich historic heritage has endowed Henan with numerous historic treasures, from primitive dwellings to earliest wheel thrown pottery. The remains of some of the earliest human settlements have been unearthed here, including the over 7000-year-old Peiligang Culture Site, the 6000-year-old Yangshao Culture Remains and the 5000-year-old Dahe Culture Remains. All these cultural remains have profound significance in the history of Chinese civilization.

Luoyang City has been the capital of nine dynasties since the time of the Eastern Zhou Dynasty (770BC-221BC). There are many historical sites to be viewed in Luoyang as well as the opportunity to purchase replicas of the famed Tang three-glaze horses. Luoyangs Longmen Grottoes, famous for its grand treasure trove of Chinese Buddhist statues, are located 12km (7 miles) south of Luoyang. First sculpted and chiseled around 493 AD when the capital of the Northern Wei Dynasty (386-534) was moved from Datong City to Luoyang, the grottoes of Luoyang house an awe-inspiring collection of sculpted Buddha and other religious subjects.

Kaifeng, one of the ancient capitals, also boasts the following buildings worthy of a visit: Iron Pagoda (Tie Ta) of the Northern Song Dynasty (960-1127), Dragon Pavilion (Long Ting) - site of imperial palace of the Song and Jin dynasties - and the 1400-year-old Xiangguo Temple which is one of the most famous Buddhist temples in China. Also on view in Kaifeng are ruins of the Shang Dynasty, an important part of human cultural and historic heritage. The Shang Dynasty Ruins, also known as the Yin Ruins, are famous because of the unique style of the large palace and its grand mausoleums, in which emperors of the Shang Dynasty are buried. The bronze vessels of the Shang Dynasty, which were both finely decorated and popularly used by the citizens of the Shang Dynasty, are well-known at home and abroad.

在动物家庭中，有一种乖巧、驯良的动物，那就是狗。它对主人忠诚，即使主人骂它，打它，它也从来不会反抗，当主人遇到危险时，它便会毫不犹豫地扑上去解救主人。

狗的嗅觉很灵敏，只要把鼻子贴在地上，它就能闻到地底下的气味和几百米外的美食。就拿搜救犬来说吧，四川发生地震后，搜救犬日夜不停地工作，救回了无数人的生命呢！

狗的种类有许多，比如狼狗、金巴，牧羊犬、狮子狗、导盲犬……最可爱的要数小金巴，它有着一身雪白发亮的毛发，两个“黑葡萄”印在上面，这双可爱的大眼睛在夜间时能放出绿色的光，怪恐怖的呢。你要是有过亲身经历，一定会和我一样，被吓得魂飞魄散。最温柔的是导盲犬，它可以帮助盲人过马路，是残疾人生命中不可缺少的一部分呢。

狗的品种不同，当然它们爱吃的食物也不一样，大部分狗狗都爱吃狗粮，但也有狗狗爱吃一些古怪的食物。有时爱吃鸡肝，但没过几天它又换胃口了，又吃起了高贵的牛肉。吃着吃着，越吃越好，竟吃上了牛排。也有的狗狗喜欢和猫抢着吃猫鱼，胆小的猫咪只好在一旁观看吃得津津有味的狗，假如你看见这个景象，一定会想起弱肉强食这个成语。猫也不是好惹的，有时急了，会在狗狗的脸上留下一条掌印，狗狗只好逃走了。

别看狗狗蛮可爱的，可它们身上有着几百万个细菌呢，它们在狗狗身上跳着、蹦着，狗狗不得不伸出锋利的爪子挠挠身，有时太用劲了，爪子钩在了毛里面，只好向主人求救了。

我的老家有一只小动物，它是一只惹人喜欢的狗它的名字叫“妞妞”，它是>我的朋友，一个非常要好的朋友。

它的眼睛黑黑的；它的耳朵又长又黑；身体像天上的满月的月亮 那么的圆；尾巴长长的，像一条长长的绳子；

又一次，妞妞生了一只小狗，我便把小狗放在妞妞身边，妞妞仔细地在照顾着小狗，让它不受到任何一点伤害。如果我想抱了一抱小狗，妞妞就不肯让我抱小狗，即使是我妹妹它也不肯。在晚上，如果很冷的话，妞妞会把小狗抱在自己的怀里，让小狗不会被一股股冷风吹到，当我看到这一幕时，心一酸，便从柜子里拿出一件小衣服，盖在妞妞和小狗的身上。妞妞和小狗便>温暖了许多，我的心便高兴了许多。

妞妞看我的眼神，变得温和了许多，因为它知道了，我对它的友好。日子一天天的过去了，我和妞妞的感情也越来越深了，渐渐我就能抱小狗了。

>这就是我的小动物----妞妞，它成了我亲密无间的好伙伴。

Our Right Attitudes Toward Animals

Your essay should meet the requirements below:

1)Describe the cartoon and deduce the purpose of the drawer of the cartoon;

2)State the negative effects of eating wild animals; and

3)Give your suggestion as to how to solve the problem.

考研英语作文范文

As is depicted in the cartoon, both the cat and snake are on the table, with tears in their eyes, waiting to be eaten by humans. Through this picture, the drawer condemns the eating of wild animals.

Eating wild animals gives rise to a lot of negative effects. In the first place, as many wild animals carry parasites, when we eat them, the parasites enter our bodies, thus causing a lot of illnesses. In the second place, since animals are an indispensable part of our environment, the extinction of some animals may disturb the natural balance. Last but not least, eating wild animals is cruel.

Since eating animals causes so many harms, we should work together to put an end to the problem. On the one hand, the government should make stricter laws to prohibit people from eating wild animals. On the other hand, all the people should realize the harms of eating wild animals and refrain from doing so.

My Mother My Mother isa kind and gentle woman. She is always very gentle. She takes good care of her children and keeps them all at school. I have one brother and two sistets. So she gets four children in all. She gives us every comfort. We all love her and she loves us also. My mother has too much to do in bringing us up. As our family is too poor to keep a servant, my mother has always to do very much work. She gets up very early and sleeps very late every day. She works hard, yet without complaining. She is also a thrifty, and industrious woman. She saves every cent that she can and keeps everything in order. As she has been busy eversince she was young, she looks older than she really is. Her face is wrinkled, her hair becomes silver white, but she works as hard as ever. Often she says to us, "work while you work, play while you play. If you do not work, you will become lazy and of no use to society." What piece of good advice this is! We must worth it well and always keep it in our mind.

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。

我家有一只小狗，名叫点点，今年三岁，毛色是浅黄色的，非常讨人喜欢，点点的鼻子黑黑的，长得及小，它天生有一种傲慢的性格。

点点是一只金毛。还记的2007年冬天，正下着鹅毛大雪，它的母亲把它生下来，一个月以后我去姥姥家把它抱了回来，但它分外的小，它就是两斤左右，点点在我家生活了一年左右，因为我家没有黄土，点点的大小便也成了一个问题，无奈之下妈妈不得不把它寄存在姥姥家，点点刚走的的那几天，我无时无刻不在想它，干什么事都无精打彩，时间久了，我也渐渐淡忘了。

至从有一天，妈妈说：好久没去姥姥家了，今天去看看吧，这使我猛的想起了被我遗忘的好朋友点点，吃过午饭，我们去了姥姥家，一见面，我还差点没有认出，当初像“豆芽形”的小狗，现在却长得又粗又高，看起来威风凛凛的，鼻子上也有一点淡淡的红色，显得格外精神。

在回家的路上，我想了许久，为什么当初的小狗到了姥姥家就长大了?也吃胖了呢?我想是因为姥姥家的饭很合它的胃口吧。呵呵，我家的小点点可爱吧。
