        熊貓介紹英語作文 篇1

          Pandas eating bamboo at the National Zoo in Washington, D.C.Despite its taxonomic classification as a carnivore, the panda has a diet that is primarily herbivorous, which consists almost exclusively of bamboo. This is an evolutionarily recent adaptation. Pandas lack the proper enzymes to digest bamboo efficiently, and thus derive little energy and little protein from it.

          While primarily herbivorous, the panda still retains decidedly ursine teeth, and will eat meat, fish, and eggs when available. In captivity, zoos typically maintain the pandas' bamboo diet, though some will provide specially formulated biscuits or other dietary supplements.

          Panda is one of the scarcest animals. People in the world like it very much. There used to be many pandas in China long ago. As the balance of nature was destroyed and the weather was getting warmer and warmer, pandas became less. But at present, the number of pandas is increasing year by year. There are now so many pandas that some are being sent to other countries so that people there can enjoy them.

          熊貓是世界上瀕危動(dòng)物之一.世界各國人民都非常喜愛它.很久以前中國曾有許多熊貓,由于自然平衡遭到破壞,氣候變暖,大熊貓?jiān)絹碓缴?但目前,大熊貓的數(shù)量正逐年增多.正因如今有這么多的大熊貓,以至于有些被派往其他國家,使那里的人民可以欣賞它們.

          Nowadays, the biggest nature park for panda in China is in Sichuan. There is a research centre for nature and wild life there. Scientists hope that one day they will have enough pandas to be set free and let them live in the wild again.

          如今,最大的熊貓自然公園在中國四川.那里是研究自然野生動(dòng)物的中心.科學(xué)家們希望有一天,他們將有足夠多的大熊貓被重新放歸野外.

          國家一級保護(hù)動(dòng)物大熊貓,你們看見過大熊貓嗎?快來看看吧!下面的就是一只可愛的大熊貓,看它吃的多香呀!笑的那么可愛。

          你們說,熊貓為什么那么少,就是因?yàn)槿祟惖钠茐膩y砍樹木,不愛護(hù)花草,破壞大氣層,才導(dǎo)致熊貓的減少,所以我們要愛護(hù)熊貓,大熊貓可是食草動(dòng)物知道嗎,最愛吃竹子,但是在動(dòng)物園里的大熊貓可不一樣飼養(yǎng)員們給他們喂水果吃。熊貓趣聞:近幾年,科學(xué)家的野外隱藏?cái)z像機(jī)發(fā)現(xiàn),雄性野生熊貓?jiān)跇渖狭粝職庀⒂浱?hào)時(shí),會(huì)抬起一條后腿,像公狗一樣,然后把尿往樹的高處撒去。尿撒得越高,雄性大熊貓的社會(huì)地位也就越高。好玩吧!跟狗一樣哈哈!真好玩。在北郊的斧頭山上,大家建立起郁郁蔥蔥的竹海與森林,形成與成都市區(qū)不同的“小氣候”,1987年,正式建成,現(xiàn)已經(jīng)發(fā)展成為一個(gè)專門從事瀕危野生動(dòng)物研究、繁育、保護(hù)教育和教育旅游的非營利性機(jī)構(gòu)。

          你們知道大熊貓?jiān)趺聪褡拥膯?科研人員發(fā)現(xiàn),大熊貓的消化道粗短而又簡單,沒有一般食草動(dòng)物細(xì)長的腸道和復(fù)雜的胃或發(fā)達(dá)的'盲腸。此外,在大熊貓的基因序列于20xx年公布之后,他們還發(fā)現(xiàn)大熊貓消化道內(nèi)缺乏一些幫助食草動(dòng)物消化纖維素和半纖維素(它們是纖維性植物飲食的主要成分)的酶。這讓科研人員感到非常困惑,缺乏這些必要條件的大熊貓是如何消化竹子的呢?

          科研人員利用基因測序技術(shù),分析5000多個(gè)核糖體RNA序列,最終在大熊貓?bào)w內(nèi)發(fā)現(xiàn)了多種消化道微生物,而且和一些食草動(dòng)物體內(nèi)的微生物非常類似。這些都有助于動(dòng)物消化體內(nèi)的纖維素,而且其中有了7種是熊貓消化道內(nèi)獨(dú)有的。拜拜!

          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, don't 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 cheng du "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 panda's 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 panda's genome sequences announced in 20xx, 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 panda's digestive tract. Bye bye!
