写作思路：确立中心，围绕选材，确定重点，安排详略，选材时要注意紧紧围绕文章的中心思想，选择真实可信、新鲜有趣的材料，以使文章中心思想鲜明、深刻地表现出来，具体范文如下：
Endangered animals refer to all wild animal species that are in danger of extinction due to their own reasons or the impact of human activities or natural disasters.
濒危动物是指所有由于物种自身的原因或受到人类活动或自然灾害的影响，而有灭绝危险的野生动物物种。
Broadly speaking, endangered animals generally refer to rare, endangered or rare wild animals.
从广义上讲，濒危动物泛指珍贵、濒危或稀有的野生动物。
From the perspective of wildlife management, endangered animals refer to the animals listed in the appendix of CITES.
从野生动物管理学角度讲，濒危动物是指《濒危野生动植物种国际贸易公约》附录所列动物。
And wildlife under national and local priority protection.
以及国家和地方重点保护的野生动物。
濒危动物研究价值
濒危动物是科学研究的试验材料，在动物学、进化学、生态学、遗传学、现代医学、仿生学等学科领域里发挥着重要作用。
如中国驯养繁殖的数万只食蟹猴和猕猴，绝大多数都被用作实验动物或用来生产抗病防病的疫苗。科研院所、大专院校、动物园以及博物馆收藏、陈列或展出濒危动物的标本，对科研教学、宣传教育、执法活动等发挥了重要作用。
以上内容参考 百度百科-濒危动物
本回答被网友采纳作文思路：首先介绍了濒危动物的定义，以及造成濒危状态的原因，接着介绍了濒危动物的特点，最后介绍了金竹驯狐猴这种濒危动物的情况。
濒危动物指由于动物分布区、栖息地的生态系统遭到严重破坏,化学污染、气候变化和人类随意捕杀等原因导致濒临灭绝的动物类群。
Endangered animals refer to the endangered animal groups caused by the serious destruction of the ecosystem of animal distribution areas and habitats, chemical pollution, climate change and human random killing.
全世界处于濒临灭绝状态的脊椎动物有100多种,约有14的物种是由于自然演化造成的。
There are more than 100 species of vertebrates that are endangered in the world, and about 14 species are caused by natural evolution.
而其余的则是由于人为的因素。中国的野生动物也有许多已濒临灭绝,如丹顶鹤、扬子鳄、大熊猫、华南虎等。
The rest is due to human factors. Many wild animals in China are on the verge of extinction, such as Red Crowned Crane, Chinese alligator, giant panda, South China tiger, etc.
濒危动物具有绝对性和相对性。绝对性是指濒危动物在相当长的一个时期内野生种群数量较少，存在灭绝的危险；
Endangered animals are absolute and relative. Absoluteness refers to the fact that the number of endangered animals in the wild is small and there is a risk of extinction in a long period of time;
相对性是指某些濒危动物野生种群的绝对数量并不太少，但相对于同一类别的其他动物物种来说却很少；
Relativity means that the absolute number of some endangered wild species is not too small, but it is relatively small compared with other species of the same category;
或者某些濒危动物虽然在局部地区的野生种群数量很多，但在整个分布区内的野生种群数量却很少。
Or although there are many wild populations of some endangered animals in some areas, there are few wild populations in the whole distribution area.
金竹驯狐猴是一种小型狐猴，头尾全长52-85厘米，头体长28-45 厘米，体重1-1.5 千克，只有小猫大小。背部皮毛浅橙色，有灰色至褐色针毛，下体黄色。
Golden Bamboo tamed lemur is a small lemur, head and tail length 52-85 cm, head and body length 28-45 cm, weight 1-1.5 kg, only the size of a kitten. The fur on the back is light orange, with gray to brown needle hair, and the lower body is yellow.
脸颊黑色，有很短的口吻，眉毛、脸颊和喉部金黄色，毛茸茸的短耳朵。通常雄性和雌性有相似的外观，但雌性上体往往稍微更灰。
The cheek is black with a short tone, the eyebrows, cheek and throat are golden yellow, and the short hairy ears are short. Generally, males and females have similar appearance, but females tend to have slightly grayer upper bodies.

从广义上讲，濒危动物泛指珍贵、濒危或稀有的野生动物。
From the perspective of wildlife management, endangered animals refer to the animals listed in the appendix of the Convention on international trade in endangered species of Wild Fauna and flora, as well as the wildlife under national and local key protection.
从野生动物管理学角度讲，濒危动物是指《濒危野生动植物种国际贸易公约》附录所列动物，以及国家和地方重点保护的野生动物。
濒危原因
1、物种自身
物种特化和遗传衰竭，往往是导致物种濒危甚至灭绝的内在原因。某些种类的野生动物在长期的进化过程中，适应了某种特定的栖息环境而产生了特别的习性（包括食性），使其难以适应变化了的环境或其他环境，最终落得“不适者被淘汰”的结局。
2、人为破坏
人类为发展经济砍伐森林、围湖围海造田、过度放牧等，直接造成了野生动物栖息地丧失，间接导致了野生动物的濒危。
