注：野生动物是 part of wildlife 以下是Wildlife:Wildlife includes all non-domesticated plants, animals and other organisms. Domesticating wild plant and animal species for human benefit has occurred many times all over the planet, and has a major impact on the environment, both positive and negative. Wildlife can be found in all ecosystems. Deserts, rain forests, plains, and other areas including the most developed urban sites, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that wildlife around the world is impacted by human activities.Humans have historically tended to separate civilization from wildlife in a number of ways including the legal, social, and moral sense. This has been a reason for debate throughout recorded history. Religions have often declared certain animals to be sacred, and in modern times concern for the natural environment has provoked activists to protest the exploitation of wildlife for human benefit or entertainment. Literature has also made use of the traditional human separation from wildlife.

例文Dear WWF,I am writing to express my concerns about the protection of elephants. As we all know, elephants are one of the most magnificent creatures on earth and play an essential role in maintaining ecological balance. However, their populations have been declining in recent years due to various human activities such as poaching and habitat destruction.Therefore, I urge you to take action to protect these beautiful animals. One way to do this is by raising public awareness of the importance of elephant conservation. This can be achieved through education programs and media campaigns, which can educate people on the devastating effects of elephant poaching and encourage them to take action.Additionally, it is crucial to collaborate with governments, organizations, and local communities in conservation efforts. By promoting sustainable tourism and livelihoods for local people, we can help reduce the demand for ivory and protect elephant habitats.In conclusion, I hope that WWF will continue to work tirelessly to protect elephants and preserve their habitats. Every effort counts, and together, we can make a difference in saving these magnificent animals.Sincerely,Li Hua重点词汇：1. Magnificent (adj.) - 壮丽的，宏伟的2. Ecological balance (n.) - 生态平衡3.

Common Name Elephant ; Elephant (Fr); Elefante (Sp) Scientific Name Elephas maximus (southern Asia), Loxodonta africana (Africa) Location Africa, Asia These large and magnificent creatures need a lot of food and freedom if they are to survive. They wander in small to large herds over sometimes incredibly large areas while consuming up to several hundred kilogrammes of plant matter in a single day. Elephants, in fact, place such great demands on their own environment that in order to survive, it will frequently bring them into conflict with man who is competing for many of these same, often scarce resources. On the ground on two continents In all, the problems facing elephants in Asia and Africa are varied and complex. To this end, WWF is involved in their conservation through 2 key programmes which address local key issues, the realities faced on the ground, and this ever present conflict with man. These programmes are: Asian Rhinos and Elephants Action Strategy (AREAS): This ambitious Programme brings together cutting edge conservation biology with trade monitoring, socio-economic analysis, and policy advocacy, promising new hope for dwindling populations of these threatened pachyderms. WWF African Elephant Programme: The Programme aims to conserve forest and savanna elephant populations across Africa by supporting projects that improve protection and management, build capacity within range states, mitigate human-elephant conflict and reduce illegal trade. Physical Description Species Description Elephants are identified by their massive bodies and their trunk, which is used to pick a variety of objects, including food. The head is large in relation to the rest of the body and the African species is noted for its very large ears. Hair is sparse. The Asian elephant has four hooves (occasionally five) on the hind foot and five on the forefoot, and the African elephant has three on the hind foot and five on the forefoot. Size Living members of the order Proboscidea have a maximum height of nearly 400 cm and a weight of up to 7,500 kg. Habitat Biogeographic realm Indo-Malayan, Afrotropical Geographical Location Africa, Asia The giant panda has a very distinctive black-and-white coat, and adults measure around 1.5m long and around 75cm tall at the shoulder. Males can weigh up to 115 kg (253 pounds). Females are generally smaller than males, and can occasionally weigh up to 100 kg (220 pounds). Giant pandas live in mountainous regions, such as Sichuan, Gansu, Shaanxi, and Tibet. While the Chinese dragon has been historically a national emblem for China, since the latter half of the 20th century, the panda has also become an informal national emblem for China, and its image is found on many Chinese gold coins. Despite being taxonomically a carnivore, the panda has a diet that is primarily herbivorous, which almost exclusively consists of bamboo. This is an evolutionarily recent adaptation, or perhaps just a very awkward one; pandas lack the proper enzymes to digest bamboo efficiently, and thus derive little energy and little protein from it. While primarily herbivorus, the panda still retains decidedly ursine teeth, and will readily eat meat, fish, and eggs when available, but their sluggish speeds, a consequence of their mainly bamboo diet, ensure that these more energy-rich foods are seldom available to them outside of captivity. In captivity, zoos typically maintain the pandas" bamboo diet, though some will provide specially formulated biscuits or other dietary supplements. Unlike most bears, but like most subtropical mammals, the giant panda does not hibernate. For many decades the precise taxonomic classification of the panda was under debate as both the giant panda and the distantly related red panda share characteristics of both bears and raccoons. However, genetic testing suggests that giant pandas are true bears and part of the Ursidae family, though they differentiated early in history from the main ursine stock. The giant panda"s closest bear relative is the Spectacled Bear of South America. (Disagreement remains about whether or not the red panda belongs in Ursidae; the raccoon family, Procyonidae; or in its own family, Ailuridae.) Giant pandas are an endangered species, threatened by continued habitat loss and by a very low birthrate, both in the wild and in captivity. Poaching is uncommon; killing a panda was punishable in China by death until a 1997 law changed the penalty to 20 years imprisonment. The giant panda has an unusual paw, with a "thumb" and five fingers; the "thumb" is actually a modified sesamoid bone, which helps the panda to hold the bamboo while eating. Stephen Jay Gould wrote an essay about this, then used the title The Panda"s Thumb for a book of essays concerned with evolution and intelligent design. The giant panda has a short tail, approximately 15 cm long. The giant panda has long been a favorite of the public, at least partly on account of the fact that the species has an appealing baby-like cuteness that makes it seem to resemble a living teddy bear. The fact that it is usually depicted reclining peacefully eating bamboo, as opposed to hunting, also adds to its image of innocence. Though the giant panda is often assumed docile because of their cuteness, they have been known to attack humans, usually assumed to be out of irritation rather than predatory behavior. Giant pandas can usually live to be 20-30 years old while living in captivity. Until recently, scientists thought giant pandas spent most of their lives alone, with males and females meeting only during the breeding season. Recent studies paint a different picture, in which small groups of pandas share a large territory and sometimes meet outside the breeding season

As of 2003 land desertification in China has 2.674 million square kilometers, accounting for 27.9% of the total land area, covering 18 provinces of the 471 counties. Caused by desertification every year in direct economic losses amounted to more than 540 billion yuan. And the rate of annual expansion of 3,436 square kilometers. According to reportsmanagement, by 2010, China will strive to achieve the basicwho can basically be governed. Then caused the causes of north-western region, accounting for 34.6% of land area. 80% of the land has occurred in varying degrees of desertification. Resulting in about the causes of desertification in China, Ma Wenyuan, researchers believe that, with increasingly frequent dust storms, desertification has drawn increasing attention. The continuous , deforestation, excessive grazing, excessive, indiscriminate exploitation of water resources and hunting, And while many factors are usually additive effect, making China"s the growing trend of desertification. First, the abuse of Ken. Because of population growth and short-term benefits, many parts of the unplanned, uncontrolled for reclamation, weed cutting forests, but also not prepared soil and water conservation and ecological maintenance, leading to desertification, but also accelerate the desertification process in ecologically fragile areas, "opened a year pasture, RBI two years the amount of sand beams become three to five years, "occurs frequently. Second, deforestation. Because the main source of energy for the burning of arid areas of fuelwood, with the increase of population, residents cut down trees, and even used sand-fixing in the shelter were not spared. Third, and overgrazing. Because long-term overuse, such as desertification, Grassland overload rate of 50%, in part, I even up to 300%, not only caused large-scale grassland degradation, desertification, degradation of an annual rate of expansion of two or three Qianwan Mu, and grassland productivity than five decreased by about ten years on behalf of the 30% to 50%. Prairie "waist deep without the fifties and sixties did not hip, knee seventies and eighties did not ankle," the jingle vividly illustrate this dilemma. Fourth, excessive. Spring and autumn every year, the influx of large numbers of people in Inner Mongolia, Gansu and other exploitation of high economic value of licorice, seaweed and herbs, plus various types of large-scale deforestation, mining engineering weeding, removal of vegetation, resulting in large areas of forest, grassland desertification. Fifth, the abuse of water resources. As the Chinese way of irrigation, flood irrigation is still a serious waste of water resources, while the Northwest and North China drought, coupled with no rational allocation of water resources and management, excessive use of water upstream of the river, causing downstream water shortages, large areas of dead vegetation, land desertification . The local residents have over-grazing sheep, but also accelerates the grassland degradation, desertification rate, the current desertification area has reached sixty thousand square kilometers, to provide endless sources of sand dust storms; other use of water resources is not enough, a lot of exploitation of groundwater has resulted in ground vegetation withered, so large areas of dead ground vegetation, land degradation. VI hunting abuse. Economic value of wildlife-rich because of habitat destruction or by a large number of poaching, the number dropped, to maintain the ecosystem balance of the food chain imbalance, indirectly causing desertification. Such as the Qinghai vole was originally the hunting falcon eats a lot, due to a large number of stolen fishing, so that the proliferation of rodents, a large area grazed grassland, leading to desertification

Siberian Tiger (东北虎) The Siberian tiger (also known as the Amur, Korean, Manchurian, or North China tiger) is the largest and most powerful subspecies of naturally occurring feline. The Siberian tiger is almost totally confined to a very restricted part of eastern Russia, the Amur-Ussuri region of Primorye and Khabarovsk, a location it shares with the Siberian leopard, where they are now being actively protected. About 10% of Siberian tiger populations reside in China. The tiger population in the Sikhote-Alin was 250 in 1992, increasing to 350 as of 2004, despite significant losses of cubs due to car accidents on the single road that crosses their territory. Illegal poaching has been brought under control thanks to frequent road inspections. It is rumoured that there are still around 20 of these tigers in the Mount Changbai area of China. As the total population of these tigers fell to 150 in the wild, many subpopulations are possibly not genetically viable, subject to potentially catastrophic inbreeding. However, Russian conservation efforts have led to a revival of the subspecies, and the number of individuals in the Primorsky region of Russia has risen from 450 to 500 in the past decade, indicating positive growth.

Tigers (Latin:Panthera tigris, of Iranian origin: tighra) are mammals of the Felidae family and one of four "big cats" in the Panthera genus. They are predatory carnivores and the largest and most powerful of all living cat species. The Indian Subcontinent is home to more than 80% of the wild tigers in the world. Tigers breed well in captivity, and the captive population in the United States may rival the wild population of the world. Most tigers live in forests and grasslands (for which their camouflage is ideally suited). Among the big cats, only the tiger and jaguar are strong swimmers; tigers are often found bathing in ponds, lakes, and rivers. Tigers hunt alone and eat primarily medium-sized herbivores such as deer, wild pigs, and buffalo. However, they will also take larger or smaller prey on occasion. Humans are the tiger"s only serious predator and often kill tigers illegally for their fur or penises. Their bones and nearly all body parts are used in Chinese Medicine for a range of purported uses including pain killers and aphrodisiacs. Poaching for fur and destruction of habitat have greatly reduced tiger populations in the wild, and it has been placed on the endangered species list.

Title: The Amazing Giant PandaThe giant panda, also known as Ailuropoda melanoleuca, is one of the most beloved and iconic animals in the world. Native to the mountainous regions of central China, the panda is easily recognized by its distinct black and white fur pattern.Giant pandas have a unique and fascinating diet. They are primarily herbivores, with bamboo comprising 99% of their diet. They have a special adaptation in their digestive system to process bamboo efficiently. Despite being classified as carnivores, pandas have a thumb-like appendage, known as a "pseudo-thumb," which helps them grip and strip bamboo shoots.In terms of physical appearance, pandas have a stout body with round faces and expressive eyes. Their black ears, eye patches, legs, and shoulders contrast beautifully with their white torso. The panda"s friendly and innocent expression makes it incredibly adorable.Another interesting fact about pandas is their low reproductive rate. Females are fertile for only a few days each year, and the chances of successful mating are quite low. As a result, conservation efforts play a crucial role in ensuring the survival of these magnificent creatures. Giant pandas are considered an endangered species due to habitat loss and poaching.Efforts to protect pandas and their habitat have shown positive results. Conservation organizations work tirelessly to preserve bamboo forests and create protected areas where pandas can thrive. Breeding programs in captivity have also contributed to increasing the panda population.Beyond their conservation significance, pandas hold a special place in Chinese culture. They are often regarded as symbols of peace, friendship, and harmony. Giant pandas are beloved by people worldwide and have become ambassadors for wildlife conservation.In conclusion, giant pandas are extraordinary animals that captivate us with their unique appearance and gentle nature. They have become a symbol of conservation and inspire us to protect the natural world. Let us continue to appreciate and preserve the remarkable beauty of the giant panda for future generations to enjoy.

Major Threats to the Panda 1. Destruction of the panda"s natural habitat. In the eleven years from 1973 to 1984, suitable panda habitat shrunk by 50 per cent in six isolated, but otherwise ideal, areas. A 1998 logging ban implemented by the Chinese government helped to slow the habitat destruction, but poaching and illegal logging are still a problem. 2. Interruption of migration routes. Bamboo, the Panda"s main food, flowers (produces seeds and dies) once every 10 to 100 years depending on the species. When the bamboo in one area flowers, pandas have to move to areas that have not flowered. Historically, it was easy for pandas to move from one area to another, but now it is not. Human population has expanded, roads and settlements have been built, and forests have been cleared for agriculture, fuelwood, and timber. These changes make panda migration difficult, often leaving pandas restricted to "islands of forest."3. Consumption of Wild Meat Although pandas are occasionally hunted for their pelts, most pandas that are injured or killed by poachers are inadvertently harmed when the pandas are caught in traps meant for musk deer, takin, bear, and other animals. Wild meat is sold in the markets and restaurants in cities nearby the reserve. Eating wild meat in China is a threat to panda survival. (Note, pandas are not sought for use in traditional Chinese medicine.)Wanglang Protects the Giant Panda by:· Patrolling the Reserve for poachers and sick or injured pandas.· Protecting the forests as a key habitat area.· Educating visitors about panda protection and environmental issues.· Supporting panda research.· Providing a corridor for panda migration between adjacent panda habitats.· Educating local residents about the value of conserving pandas.· Supporting economic development of local communities to minimize their need to use panda habitat for to provide for their livelihood.How You Can Protect Pandas· Know and follow the regulations of the Reserve.· Don"t purchase or eat any kind of wild meat.· Make a donation to panda conservation at Wanglang Nature Reserve· Purchase souvenirs at the Reserve, a portion of which supports panda conservation programs at Wanglang.· Join an environmental organization to protect wildlife.· Tell a friend about Wanglang and panda protection.

1. 以东北虎为题写一篇400字作文 东北虎因为起源于亚洲的北部，所以又被称为西伯利亚虎。在历史上，东北虎又是位老寿星，有三百万年的进化史。东北虎是大型捕食性猛兽，身长体重，强悍凶猛，与其它虎种相较，个体最大，体色最美，堪称“百兽之王”。 东北虎是典型的林栖动物，在我国长白山区，主要生活在针阔叶林和阔叶林中的山崖间和山坡多石砬子的地方，也常到灌木丛和高草中觅食。 东北虎爪子长达十厘米，比钢刀还锋利，犬齿长达六厘米，犹如尖刀利剑。东北虎体型庞大，平均体长为2。8米左右，尾长0。9~1米。虎身条纹常为赤褐色，背毛长44~45厘米，腹毛长55~65毫米；夏毛较深，较短。东北虎的平均寿命约为20岁。 东北虎以捕猎动物为食，捕猎对象为狍子，鹿，野猪等有蹄动物；东北虎性极机警，走起路来和猫一样，毫无动静，行走能力很强，一昼夜能走八十至九十公里，跳跃高度达两米；东北虎还会游泳，但不会爬树。 在二十世纪初，我国长白山地区的东北虎有百头之多，但由于后来人类大面积砍伐森林，大量捕杀野生动物，处于食物链顶端的东北虎的食物被剥夺。此外，人类为取虎骨，虎皮而乱补滥杀的行为，目前，野生东北虎在中国的分布已退至松花江南岸，集中在中俄边境地带，数量仅为十只左右。 目前对东北虎的保护分两种方式，一种为栖息地保护，一种为异地保护。我国 *** 为保护东北虎建立了长白山自然综合保护区和黑龙江省七星砬子东北虎保护区，进行栖息地保护。而各个动物园，主要进行异地保护。 世界野生动物基金会已将东北虎列为全球十大濒危动物之首。 2. 以东北虎为题目,写一篇英语作文,写它少的原因以及解救它的措施 Siberian tiger is the largest subspecies of tiger.

And we should try our best to protect them.。 8. 关于东北虎的说明文 东北虎是现存体重最大的猫科亚种（除了杂交动物 狮虎兽），其中雄性从头到尾体长可达3.2米左右，尾长约1米，体长1.6~2.1米，一般体重150~250公斤，有记录的最大野生东北虎体重达到450公斤，为原苏联捕获。 东北虎主要分布于中国的东北地区，国外见于西伯利亚。体色夏毛棕黄色，冬毛淡黄色。 背部和体侧具有多条横列黑色窄条纹，通常2条靠近呈柳叶状。头大而圆，前额上的数条黑色横纹，中间常被串通，极似“王”字，故有“丛林之王”之美称（另一说法：“汉字‘王"，是根据虎头斑纹之状所造的象形文字”）。 耳短圆，背面黑色，中央带有1块白斑。犬栖居于森林、灌木和野草丛生的地带。 独居，无定居，具领域行为， 夜行性。感官敏锐，性凶猛，行动迅捷，善游泳。 捕食大中型哺乳动物， 偶食小型哺乳动物和鸟。[编辑本段]分化 在朝鲜半岛分布的虎，曾被认为是一个单独的亚种-----朝鲜虎（KOREAN TIGER）。 据说毛色和普通东北虎不同，而且体型要更小。朝鲜虎学名为Panthera tigris coreensis ，由Brass于1904年定名。 由于朝鲜半岛的虎几近灭绝，所以无从考证。在没有十分确切的证据下，国际上普遍把朝鲜半岛产的虎列类东北虎。 [编辑本段]生活习性 东北虎主要分布在我国东北的小兴安岭和长白山区。它体魄雄健，行动敏捷，肩高1米以上，身长2.8米左右，尾长约1米，体重可达350多公斤，有“丛林之王”的称号。 东北虎的毛色鲜明美丽，虎爪和犬齿利如钢刀，锋利无比，长度分别为6厘米和10厘米，是撕碎猎物时不可缺少的“餐刀”，也是它赖以生存的有力武器。它还有条钢管般的尾巴。 东北虎捕捉猎物时常常采取打埋伏的办法，悄悄地潜伏在灌木丛中，一旦目标接近，便“嗖”地窜出，扑倒猎物，或用尖爪抓住对方的颈部和吻部，用力把它的头扭断；或用利齿咬断对方喉咙；或猛力一掌击到对方颈椎骨，然后慢慢地吃。 东北虎一般住在600—1300米的高山针叶林地带或草丛中，主要靠捕捉野猪、黑鹿和狍子为生。 它白天常在树林里睡大觉，喜欢在傍晚或黎明前外出觅食，活动范围可达60平方公里以上。 常言道：“谈虎色变”，“望虎生畏”。 在人们心目中，老虎一直是危险而凶狠的动物。然而，在正常情况下东北虎一般不轻易伤害人畜，反而是捕捉破坏森林的野猪、狍子的神猎手，而且还是恶狼的死对头。 为了争夺食物，东北虎总是把狼赶出自己的活动地带。东北人外出时并不害怕碰见东北虎，而是担心遇上吃人的狼。 人们赞誉东北虎是“森林的保护者”。[编辑本段]生长繁殖 东北虎一年大部分时间都是四出游荡，独来独往，没有固定住所。 只是到了每年冬末春初的 *** 期，雄虎才筑巢，迎接雌虎。不久，雄虎多半不辞而别，把产仔、哺乳、养育的任务全部推给雌虎。 雌虎怀孕期约3个月，多在春夏之交或夏季产仔，每胎产2—4仔。雌虎生育之后，性情特别凶猛、机警。 它出去觅食时，总是小心谨慎地先把虎仔藏好，防止被人发现。回窝时往往不走原路，而是沿着山岩溜回来，不留一点痕迹。 虎仔稍大一点，母虎外出时将它们带在身边，教它们捕猎本领。一二年后，小虎就能独立活动。 东北虎的寿命一般为28年左右。 大约是人类的50到60岁。 [编辑本段]爆发力和攻击力 东北虎如传说的山神一样，拥有火一样的神灵目光。它的身体厚实而完美， 背部和前肢上的强劲的肌肉在运动中起伏，巨大的四肢推动向前，是那样的平稳和安静，看起来就象在丛林中滑行一样，它相对地拥有尖硬的锯牙钩爪，拥有5个非常锐利的虎爪，使用时伸出，不用时缩回爪鞘避免行走时摩擦地面。 它生性内向，胆小孤独、多疑、凶猛、强壮有力，动作敏捷，在丛林中出没无常，一般人很难亲眼目睹野生的东北虎。传统看法其它虎种均为东北虎向地球其它地区扩展分化出来的。 在生态环境中也处于顶层的王者地位。 中国科学家在解剖东北虎的时候，发现它的肌肉一打开之后，比最好的健美运动员的肌肉还要好看，还要结实，肌纤维极为粗，浑身上下，很少能找到多余的脂肪，几乎很难见到脂肪，强壮的骨骼附有强大的肌肉，证明这种动物有极强的爆发力。 虎的爆发力有过实证，在北京动物园狮虎山兽舍的水泥地面上有一道被东北虎抓裂的裂痕。剥掉皮的狮虎惊人的相似。 [编辑本段]种群现状 东北虎的经济价值极高，传统看法认为虎的肉和内脏可入药治疗多种慢性疾病，一只成年虎的价值相当于30多张黑貂皮，也只因为这样，东北虎遭到无情的捕杀。虎的繁殖率也较低，它的寿命一般为25年左右，三四岁时性成熟，每年12月至翌年2月 *** ，怀孕期105~110天左右，每胎一般产三四仔。 幼虎吮吸母亲乳汁长大，要跟随母虎一二年才独立生活。想想看，人们对东北虎的捕杀率大大超过它的繁殖率，这是东北虎濒临灭绝的直接原因。 滥伐森林、乱捕乱杀野生动物，严重地破坏生态平衡，也是造成东北虎濒临灭绝的另一个重要的间接原因。我们知道，森林是虎的生存环境，在这个环境中也包含着虎的猎食对象——野猪、鹿等。 近年来由于偷猎者甚多，致使虎的捕食动物也大为减少，因此，维持野猪、鹿等有蹄动物与虎之间的生态平衡是很重要的。据考查，在一。 9. 介绍老虎的作文250~300字以内 你养猫吗？老虎是猫科动物，但比其它猫科动物更具有猫科动物的特征，老虎很像猫。如果你在猫的额头画个“王”字，再把它放大几倍，就可以大致看到老虎的样子了。有个成语叫“照猫画虎”，很形象地说出了猫与老虎在外貌上的相似性。当然，老虎一般是黄色的，皮毛上有斑斓的条纹。白虎黑虎但闻其名，不见其物，流于传说罢了。 俗语说“猫是老虎的老师”，但显然老虎青出于蓝而胜于蓝了。老虎的威势不是猫能比滴。我们看到小猫发怒作势只会觉得可爱，不会感到恐惧，而老虎作势欲扑却能让人肝胆欲裂，魂飞魄散。即使在动物园，一只老虎瞪视着你，也能让你感到压力，浑身不自在。虎视眈眈，岂可小看？ 10. 介绍老虎的作文250~300字以内 你养猫吗？老虎是猫科动物，但比其它猫科动物更具有猫科动物的特征，老虎很像猫。 如果你在猫的额头画个“王”字，再把它放大几倍，就可以大致看到老虎的样子了。有个成语叫“照猫画虎”，很形象地说出了猫与老虎在外貌上的相似性。 当然，老虎一般是黄色的，皮毛上有斑斓的条纹。白虎黑虎但闻其名，不见其物，流于传说罢了。 俗语说“猫是老虎的老师”，但显然老虎青出于蓝而胜于蓝了。老虎的威势不是猫能比滴。 我们看到小猫发怒作势只会觉得可爱，不会感到恐惧，而老虎作势欲扑却能让人肝胆欲裂，魂飞魄散。即使在动物园，一只老虎瞪视着你，也能让你感到压力，浑身不自在。 虎视眈眈，岂可小看？。

If they are going to focus on something, they should do it on civil rights. 　　A: Yes, but we canu2019t deny that animals are vulnerable(脆弱的，易受伤的), defenseless(无防备的), and are completely at the mercy of human beings. 　　B: I understand your point, but we continue to have transgressions(违反，违法) against human rights. If so much attention werenu2019t devoted to the topic of animals, we would then concentrate more on saving a human being instead of protecting a koala. 　　A: You canu2019t compare apples and oranges; I believe that both topics are important and that we canu2019t ignore them, the mistreatment of animals can cause a great environmental imbalance. I believe that governments should prohibit activities like poaching. 　　B: Well, you are right on that point. This is the reason that I donu2019t buy leather and I try to buy synthetic(人工合成的) products. 　　A: At least youu2019re doing your part(帮助完成某个目标). My contribution is to have a pet in the house that I treat like a member of the family. 　　B: As long as you donu2019t treat it better than your wife, itu2019s fine. 　　关于保护动物英语对话2 　　保护野生动物 　　A; what do you think of the way people use and treat animals? 　　B: I think most people treat animals well, but we are often cruel to animals. When we raise animals or food, the conditions they live in are often poor. 　　A; perhaps people should stop eating animals. We could grow more crops. 　　B; what would you do with all the animas? You couldnu2019t just let them go. Besides, some people would still hunt them. Meat has become an integral part of our diet. 　　A; we could provide them with better conditions anyway. We should certainly try to improve the conditions at zoos. We should try to recreate the natural conditions as much as possible. 　　B: thatu2019s true. I think zoo are a good idea, because they allow people to get close to animals. I think itu2019s good for kids to see wild animals. 　　A; I agree. Iu2019m an adult and I love going to the zoo. I donu2019t like animals experiments though. I believe that we can do tests in other ways. 　　B; I read that the number of animals being used in experiments is falling dramatically as new techniques are being introduced. 　　A: thatu2019s good news. The good thing is that most people treat their pet well. 　　B; sometimes you read about people who have been cruel to pets or other animals, but those stories are rare. 　　A: have you every given money to any of the charities that take care of animals. 　　B: yes, I have. They do an excellent job. 　　A:你怎么了人们使用和对待动物的看法? 　　B：我想大多数人对待动物很好，但是我们经常残忍的动物。当我们提高食用动物方面，他们的生活条件往往很差。 　　A:也许市民应停止食用动物。我们可以种植更多的作物。 　　B:你会怎么做所有阿尼马斯?你不能只是让他们走。此外，一些人还会捕捉。肉已成为我们的饮食的一个组成部分。 　　A:我们可以提供更好的条件他们。我们当然要设法改善动物园的条件。我们应该努力创建尽可能的自然条件。 　　B：这是事实。我认为，动物园是一个好主意，因为它们让人们亲近动物。我认为，孩子们高兴地看到野生动物。 　　A:我同意。我是一个成年人，我喜欢去动物园。我不喜欢的动物实验，但没有。我相信我们可以在其他方面的测试。 　　B:我读的动物的数量正在实验中使用的是急剧下降的新技术正在实施之中。 　　A：这是好消息。令人欣慰的是，大多数人对待自己的宠物好。 　　B:有时你阅读的人谁被残酷的宠物或其他动物，但这些故事是罕见的。 　　A:每给你钱的慈善机构的任何照顾动物。 　　B:是的，我有。他们表现非常出色。 　　关于保护动物英语对话3 　　A: I do think people are consuming more and more habitat region of wild life. As authority has provided the number of wilds are decreasing, I think it due to man kind. 　　B: I couldn"t agree with you more. Last time I went to Sichuan, pandas can be found everywhere in the bamboo forest. But only 10 years has passed, panda merely can be found in zoos or protecting regions there. I think animal extinction is more and more common now. 　　C: I can only partly agree with former two, because I think animal"s termination is not to blame human only. Enviormental changes really matters to animals. Even global warming is not totally ours fault, it is reported by Australian researcher, herts of cows can leave tons of waste gases into the air daily which is tested out most CO2. That"s much more than human can produce a day. 　　D: Yes, I surpport C for evolutional theory of Darwin"s reason. I think species is developping their genes when passing down, maybe those extincting animals are those who don"t fit the surroundings?

The Tibetan antelope is a medium-sized bovid which is about 1.2 metres (4 feet) in height. It is native to the Tibetan plateau including China"s Tibet Autonomous Region, Qinghai province, and Xinjiang province; India near Ladakh and formerly western Nepal. The Tibetan antelope is also known commonly by its Tibetan name chiru. The coat is grey to reddish-brown, with a white underside. The males have long, curved-back horns which measure about 50 cm (20 inches) in length.Despite its classification in the Antilopinae subfamily, recent morphological and molecular evidence suggests that the Chiru is more closely allied to goats and the subfamily Caprinae (Gentry 1992, Gatesy et al. 1992, Ginsberg et al. 1999).Tibetan antelope are gregarious, sometimes congregating in herds hundreds strong. The females migrate up to 300 km yearly to calving grounds in the summer where they usually give birth to a single calf, and rejoin the males at the wintering grounds in late autumn (Schaller 1998). Chirus live on the high mountain steppes and semi-desert areas of the Tibetan plateau such as Kekexili, where they feed on various forb and grass species. The average life span is about eight years.Tibetan antelope are listed as endangered by the World Conservation Union and the United States Fish and Wildlife Service due to commercial poaching for their underwool, competition with local domesticated herds, and the development of their rangeland for gold mining. The Chiru"s wool, known as shahtoosh, is warm, soft and fine. The wool can only be obtained by killing the animal; Its numbers have dropped accordingly from nearly a million (estimated) at the turn of the 20th century to less than 75,000 today. The numbers continue to drop yearly. The struggle to stop illegal antelope hunting was portrayed in the 2004 film, Kekexili: Mountain Patrol.

You need to walk towards happiness. 　　不要等待好事降临，你要向幸福进发。 　　You will need a pot of broth for poaching. 　　你需要一锅汤来煮。 　　What is right for us need not be right for others. 　　对我们来说是对的东西，对别人来说未必正确。 　　Mommy, you don"t need to stay while we talk. 　　妈妈,我们谈话时你不必陪着. 　　Businesses need to train their workers better, and spend more on R&D. 　　各企业需要更好地培训工人，并且在研发方面加大投入。 3.高三下册英语必修四知识点 　　1、no和not的区别 　　not和no都是作为副词，这里可以替换使用，意思是不，并没有区别，但是no和not在否定回答的用法不同。 　　no和not这两个单词的元音字母o的读音不同。no的o发音为长音/u0259u028a/，not的o发音为短音/u0252/。 　　no可以做形容词，not不能做形容词。no作为形容词，意思是没有。 　　no还能作为名词使用，not不能作为名词。no作为名词，意思是否定，否认。 　　no和not在否定回答的用法不同。 　　2、no和not的例句 　　There are no clouds in the sky. 　　天上没有云。 　　We went no farther than the bridge. 　　我们走到桥边就不再往前走了。 　　I have no ink. 　　我没有墨水。 4.高三下册英语必修四知识点 　　1、什么是同义句转换 　　同义句转换就是将一个句子用另一种形式表达出来，而且意思不变。因此，掌握的句型越多，做题就越方便、快捷、容易。但每种练习的方式总有一定的规律可循。比如do well in换成be good at换成不同的语态，比如主动变被动。 　　2、英语改同义句的方法 　　运用同义词或同义词组：这类题目首先要注意比较上下两句，找出需要改动的地方，运用同义词或同义词组进行转换，还要注意把握两句的时态、数的单复和主谓一致等。 　　运用反义词或反义词组：这类题目可以否定句中的动词或形容词，是两句意思相符，仍然要注意动词时态一致。 　　动词短语转换成介词短语：此类题目关键就是使用恰当的介词短语，还要注意动词时态一致。 　　单句转换成复句，或者复句转换成单句：此类题目需要熟悉一些重要的句型和短语，还要注意了解相关转换类型。 5.高三下册英语必修四知识点 　　(1) 现在完成时可以表示一个已经完成的动作，而现在完成进行时则表示一个正在进行的动作： 　　I have read the book. 我读过这本书。 　　I have been reading the book. 我一直在读这本书。 　　注：有少数动词(如work, study, live, teach, stay等)在表示持续一时间时用这两种时态含义差不多(只是用现在完成进行进更强调动作的持续性)： 　　How long have you worked [been working] here? 你在这儿工作多久了? 　　I"ve lived [been living] here since 1988. 自1988年以来我就一直住在这儿。 　　(2) 现在完成时通常只陈述事实，而现在完成进行时还可表示一种感感情XX： 　　I have waited for two hours. 我等了两小时。(陈述事实) 　　I have been waiting for two hours. 我等了两个小时。(等得好辛苦) 　　(3) 现在完成进行时通常用来谈论较短暂的动作或情况，若要谈论时间延续较长的动作或情况或永久性情况，则通常用现在完成时： 　　He has lived in Paris. 他(一直)住在巴黎。 　　He has been living in Paris. 他(目前)住在巴黎。(表暂时性) 　　(4) 不用于进行时态的动词通常也不用于现在完成进行时，但它们可以用于现在完成时： 　　I"ve only known her for two day. 我认识她刚刚两天。 　　(5) 现在完成进行时不用于被动语态，若要用可用现在完成时的被动语态代替： 　　The house has been painted for a month. 这房子已漆了一个月。

ExtinctionExtinction is a natural process. Many species had ceased to exist before humans evolved. However, in the last 400 years, the number of animals and plants becoming extinct has reached crisis point. Human population levels have risen dramatically in the same time period and man"s predatory instincts combined with his ruthless consumption of natural resources are directly responsible for the situation. DodoThe Dodo is a classic example of how human behavior can cause irreparable damage to the earth"s biological diversity. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island"s trees and lived unthreatened until humans arrived in 1505. The docile bird became a source of food for sailors and lacked the ability to protect itself from animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and the last one was killed in 1681.Endangered AnimalsIn 2002 many animals remain threatened with extinction as a result of human activity. The World Wildlife Fund works tirelessly to raise awareness of the predicament facing these animals and find ways to protect them. By focusing on a number of high profile, "charismatic icons" such as the rhino, panda, whale and tiger, the WWF aims to communicate, "critically important environmental issues". The organization"s ultimate goal is to, "stop the degradation of the planet"s natural environment and to build a future in which humans live in harmony with nature".RhinosThe Rhino horn is a highly prized item for practitioners of Asian medicine. This has led to the animal being relentlessly hunted in its natural habitat. Once widespread in Africa and Eurasia, most rhinos now live in protected natural parks and reserves. Their numbers have rapidly decreased in the last 50 years, over half the remaining rhinos disappeared in the 1970s, and the animals remain under constant threat from poachers.The Giant PandaThe future of the WWF"s symbol is far from certain. As few as 1000 remain in the wild, living in small isolated groups. These groups have been cut off from each other as a result of deforestation and human expansion in to their natural habitat. The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison. However, the panda"s distinct black and white patched coat fetches a high price on the black market and determined poachers still pose one of the most serious threats to the animals continued existence.WhalesThe International Whaling Commission meets every year. The agenda covers ways to ensure the survival of the species and the complex problems arising from countries such as Japan, wishing to hunt certain whales for "scientific" purposes. Despite the fact that one third the world"s oceans have been proclaimed whale sanctuaries, 7 out of 13 whale species remain endangered. The plight of the North Atlantic Right Whale is particularly serious. Hunted for their rich supply of oil, their numbers have dwindled to just 300. Collisions with ships, toxic pollution and becoming entangled in fishing nets are other major causes of whale deaths.TigersThe last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5000 and 7000 and The Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tiger bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.Take ActionThe WWF is actively involved in many areas of the world fighting to protect the natural habitats of endangered animals from further damage and curb the activities of poachers. They also work to influence governments and policy makers to introduce laws aimed at reducing the threat of pollution and deforestation. Our own individual efforts at home and in the workplace can also make a difference. By reducing waste and pollution, saving water, wood and energy, and reusing and recycling whenever possible, we can reduce the possibility of even more animals being lost, never to return.Your turnDo you think enough is being done to protect animals? If not, what else could be done? Send us your opinions.Far out into the ocean to the north and west of Britain are the cold wild islands of the Outer Hebrides of Scotland. They make a line of beautiful beaches 150 miles long. Further west is the small group of islands called Saint Kilda. They are cold and wild too, but without beaches. The islands are tall volcanic rocks hundreds of metres high. For thousands of years, people lived on these islands. In 1930 the last people, there were only 36 of them, had a meeting and decided to leave. The biggest island in the group is called Hirta. Sheep still live there without any people. When you arrive by boat, you see very tall black rocks all around. Some big rocks make their own small islands. This true story happened on the tallest of the rocks – “Stac An Armin” in 1840.In those days, people still lived on the islands of Saint Kilda. Their stone houses were all in one village by the ocean at the bottom of a tall dark hill. The houses only had one room – for people and sheep, which used to live with them in the winter and spring. Two men from the village, McDonald and McKinnon, were on the rock. It was their work to collect birds – some for food, some to make shoes or hats with. Some dead birds they put in the earth to help their vegetables grow. They found one strange big bird. It was sleeping. They decided to bring it home to the village.I think people in the village were interested in the bird. We now know that this was a Great Auk, a kind of swimming bird that lived in many parts of the North Atlantic. It was big and strong and had a loud cry. They began to talk with the other people in the village about what they should do with it. After two days, the weather got worse and then there was a terrible storm. The people in the village decided that this was because of the bird and they killed it. This was the last example of the Great Auk in Britain. Four years later, the last Great Auk in the world died in Iceland.We know the Great Auk died out because of people. But where did the people of Saint Kilda go? This is more difficult to explain. Some say that they were bored living on the island so far from modern cities. Other people think that the problem was tourists, who began to visit Saint Kilda at the end of the 19th century. A new theory says that using too many dead birds as fertilizer made their food unhealthy. I think it was a mistake to kill the auk.mistake that resulted in killing this bird. The day after the people brought the bird home, the weather got worse and worse. At that time, they had less knowledge about nature, they could only believe in God to help them decide what was wrong and what was right. So it was so easy to make mistake about what they didn"t know and it happened by mistake. The article is very clear about that. But at the first they thought they should bring it home and kill it for food. That is not good. Unfortunately, it was the last bird.”Oswaldo Herrera writes “This article is very interesting, and we need to think about it. Nowadays we are destroying our world and furthermore, the animals and plants that exist in it. There are a lot of warnings but most of the time we do not care about them - I think that this articles helps us to reflect and to be conscious about all the animals and plants that we are destroying with all the pollution that we generate nowadays.”

至此粉红电影进入了它最为辉煌的年代，直到1973年。这一时期粉红电影无论从创作的数量还是水准上都是极为成功的。粉红电影数量占到了整个日本国内电影数量的一半以上。仅日本东京就有大约500家的成人影院播放粉红电影。进入70年代后，迫于经济困难的原因，早些时候制作粉红电影的电影公司从5家变成了3家。其中两家日活和东映开始制作成人电影。20世纪70年代中期日活又出现了新的电影类型SM Pink，代表作是小沼胜导演的《受辱的妻子》，该片是日活第一部取得巨大成功的SM影片 。又一位代表人物田中登则以Angel Guts 系列开创了Violent Pink电影的先河。另外一家公司东映所拍摄的相同题材的电影叫做Pinky Violence，代表作包括铃木则文的《兽欲学园》。粉红电影和早期的浪漫色情电影应该是很相似的，影片拍摄的媒质都是胶片，可以称为电影。有剧本，需要后期的声音合成，影片时长都控制在1个小时左右。粉红电影有着严格的预算限制，但Roman pornography的制作费用是十分可观的。这一点是与粉红电影最大的不同之处。Roman pornography通常的制作周期为一周到十天。粉红电影中的性爱场面是一种形式，没有真正发生的。而在后期的Roman pornography和AV中性爱场面大部分是确实发生的。这些场面由于日本电影制度的要求是要打码的。直到今天AV也都是要求有马赛克的，无论是薄码还是厚码。而我们看到的无码AV其实是违法的。在粉红电影中我们是看不到马赛克的，一个原因是源于导演对镜头的处理和把握。另外制作公司没有足够的资金去后期处理增加马赛克。后期的Roman pornography是日本AV的雏形，AV的拍摄媒质是录映带，不能视为电影。不过在时间长度上依然继承着1小时作用的传统。随着20世纪80年代后AV的风靡，Roman pornography这一类型电影也逐渐消失，而粉红电影则逐渐发展为主流电影，电影长度由60分钟，增加到90分钟，一部标准电影的时长。日活公司粉红电影时代和浪漫色情电影时代的代表分别是若松孝二和若松孝二有粉红电影教父之称，是日本电影历史上最为坚挺的导演。不仅内容广泛，题材也极具争议。除了宣扬porno之外，命运，人性，政治，暴力等诸多元素也使得他的电影极为绚烂但也极为晦涩。他是日活公司早期的代表人物之一。1965年若松离开了日活，因为日活不支持他颇具争议的电影Secret Act Behind Walls参展柏林国际电影节。不用受到电影公司体制的约束之后，若松孝二开始了他对立的创作，他的个人风格的特点更加突出。甚至变得有些狂野。这一时期的作品耸人听闻，离奇古怪，超现实超自然。比如Contemporary History Of Rape In Japan　，When The Embryo（胚胎） Goes Poaching（水煮） ，Ecstasy Of The Angels都是最好的体现。若松孝二是至今仍然活跃在日本影坛的老导演之一。最近的一部作品是《完全饲育之赤色杀机》。 神代辰巳是日活Roman porno绝对代表人物，有着日活porno之王的美誉。神代是一位游走在日本主流和非主流之间最成功的一位导演，他的作品无论是在日活系中，还是在百年日本佳片中都很有代表性。

植脂末含反式脂肪酸 植脂末又称奶精，含有氢化植物油、酪蛋白酸钠、葡萄糖浆、稳定剂、乳化剂、抗结剂等，是一种独特的水溶性乳化、混浊剂，是一种新型食品添加剂。 植脂末在水中形成均匀的奶液状，可以改善食品的组织结构，增香，使口感细腻、润滑厚实，因富有奶味。而且由于植脂末混溶性好，“奶”感强，在食品加工中可代替奶粉或减少用奶量，在保持产品品质的前提下降低生产成本。一般用于珍珠奶茶的植脂末的含脂率在32%。 然而，植脂末中的植物油实际上是反式脂肪酸。这种脂肪酸是在把植物油的不饱和脂肪酸变成饱和或半饱和脂肪酸的过程中产生的。而经常摄入反式脂肪酸，可以升高人体血液中的低密度脂蛋白，减少高密度脂蛋白，从而诱发血管硬化，增加心脏病、糖尿病、脑血管意外的危险。

1 准备材料。三四个2.5升的健力宝瓶或可乐瓶， 若干X光片，几个化学器材用的3号和4号软胶塞，一整套单车气门心，剪刀、小刀各一把，透明胶、双面胶和绝缘胶布，502胶水一支。 2 机翼制作。用剪刀将X光片裁成大小相同的直角梯形28块，梯形长12cm，高6cm，斜腰和长底夹角约45度。另裁4个同上规格但高为8cm，短底相连接两面重叠的梯形（用作机翼的表面）。用双面胶将7小块梯形紧密粘成一个厚的梯形，使之平直平坦，然后用一个大的双面梯形将其紧密包住并粘紧。为使机翼的厚面平整，可用剪刀或小刀修平修直，然后将机翼的厚面用绝缘胶封住。最后，将机翼两边长出的部分向外折成90度。这样，按上述方法将其余的X光片做成三个机翼。 3 机身制作。取一个健力宝瓶（瓶头弧线过度比较自然，作火箭头利于减小空气阻力）在离下端11cm处将其横截剪开,用绝缘胶将带瓶口的部分粘紧在另一个瓶子的底部，用绝缘胶在接口处多缠绕几圈以牢固。 4 气塞制作。取一个4号的软胶塞，用开洞工具在胶塞的底部正中处开一个比气门芯套筒稍小一点的平直洞，然后用小刀横切去细端约0.6cm；将气门芯套筒上一个面积较大的“戒指”（五金店有卖），从软胶塞的细端往上把气门芯装好，套上一个同样的“戒指”，拧上螺丝，稍微紧就可以。最后将气塞用磨刀石磨成圆柱体，达到刚好能够完全进入可乐瓶口或稍紧一点，装上气门芯即可使用。 5 炮头制作。取一个3号软胶塞用小刀将其削尖且圆滑。 6 组装机翼。取一个健力宝瓶剪一个长比机翼长稍长的两面相通的圆柱体，然后用透明胶和绝缘胶将4个机翼4等分紧密粘好。最后，将粘好机翼的圆柱体套在水火箭的底部使其与瓶口相平（这不一定是最佳位置，可在飞行实践中上下调节寻找确定），用绝缘胶缠绕粘紧。 7 其他。为增大气塞和瓶口的接触面以增大瓶内气压，可用小刀将气塞大端削细一点并使之圆平粗糙。由于机身增长了一节做火箭头，火箭头部分较轻不平衡，可适当往里面塞纸以达到平衡。为尽可能减小空气阻力，将用软胶塞做成的炮头用502胶水在火箭头瓶口粘好。 按以上方法一个简单的水火箭便制作完成。根据我们研制的水火箭，通过实践的改进，水平方向飞行可达160米左右，竖直方向飞行可达40~50米。 水火箭发射方法： 1 水量调控。水火箭用水量和火箭容气空间有一定的比例，不能太多也不能太少，最佳用水量约为火箭容气空间的1/4到2/5之间（2.5升的空间大约装600毫升左右，可多试验几次寻找确定）。 2 发射角度。水平方向飞行，由于空气的阻力，发射的最佳角度在50到55度之间，不同的水火箭可能不同，可通过控制变量的方法试验确定。（我们制作的水火箭最佳角度是53度左右）。竖直方向飞行则为90度。 3 气塞使用。气塞的使用原理是通过压缩软胶塞体积膨胀来调节气塞的松紧程度，压缩越厉害体积膨胀越大，气塞越紧，要把气塞冲出来的气压就越大，即火箭获得的动力越大。具体使用方法如下：首先拆下气塞的气门芯，将气塞在原形塞进火箭的瓶口内，然后用套筒（一种专门用来拧螺丝的工具，五金店有卖）拧紧气塞的螺丝，最后安装气门芯即可加气使用。（注：拧紧程度可按需要来调节。） 4 发射稳定调控。仅讨论水平方向的发射。需要制作一个发射台，发射台要配有导航轨道，导航轨道不要太长也不要太短，一般长为60cm（可用三个教学用的大三角板和两根扫帚柄拼凑而成，为减少扫帚柄作导航轨道时对水火箭的摩擦，可用透明胶粘贴扫帚柄或如图例所示的模型）。无风天气时，正对目标按最佳发射角度（指发射轨道与地面的夹角）发射。刮风天气时，应视风力和风向适当调偏与发射目标的方向，保持最佳发射角度发射。 5 注意事项。发射时，确保火箭和轨道的平直一致，若偏离1~2度都会影响飞行的平稳性而呈“8”字型飞行。用气筒打气时，要尽可能平稳，打气频率不要太慢应快点。要尽可能将气塞塞紧，可通过拧紧气塞的螺丝来调节，气塞塞得越紧瓶内气压越大而火箭的动力就越大。 取第一个瓶子，称之为A瓶。在瓶子上下1-1、2-2的位置各画一条线，两条线位置的决定方法如下。 1-1：选瓶上弧线曲度与火箭泡棉头曲度相近处。 2-2：选瓶子下方曲线转直点的下方约0.5cm处。 自1-1线上方、2-2线下方约0.5cm处用美工刀（或剪刀）切（剪）开。 用剪刀慢慢修剪至画线处，尽量使其平整，以便与B瓶衔接时可以较为密合。 将火箭泡棉头放置於A瓶上方，由正上方看泡棉头是否对准保特瓶之正中央位置。若已放正，则使用电工胶布缠绕於相接处，加以固定。 取另一个瓶子称之为B瓶，将瓶盖卸下，然后将喷嘴由保特瓶开口处旋紧。 将A、B瓶相连接。然后至於平坦之桌面或地上滚动，看看是否连接平整，滚动是否平顺。若是，则以电工胶布加以固定。 连接完成图 取第三个瓶子，称为C瓶。在瓶子3-3、4-4之位置各画一条线。 3-3：选瓶子上方曲线转折点的下方约0.5cm。 4-4：选瓶子下方曲线转折点的下方约0.5cm。 自3-3线上方、4-4线下方约0.5cm处用美工刀（剪刀）切（剪）开。 C瓶完成图 将厚纸板对折，然后用铅笔画出四个梯形。然后用剪刀沿线剪开。 注：尾翼之尺寸、形状，可以做不同的变化，以测试 其对飞行有何影响。 同样以投影片至做出与厚纸板规格相同之梯形。 将制作好之投影片包覆於厚纸板梯形之外侧，可以先使用双面胶带将投影片及厚纸板接合在一起，然后使用电工胶布将其三边贴过。 用双面胶带贴於摺起部分之底部。此步骤为了将做好之四个尾翼年贴於C瓶。 四个尾翼完成图。 将四片尾翼年贴於C瓶上，需确定为十字对称，如此才能平衡。 先以电工胶布黏贴於尾翼两侧，黏贴时须注意电工胶布的长度须够长，上方需比尾翼高约一个胶带的高度，下方反折入C瓶内，以增加牢固程度。再以电工胶布缠绕於尾翼上方约两圈。 将C瓶与B瓶用电工胶布做连接。 注：同样须注意保持水火箭箭身的笔直以确保飞行方向的准确。

聚丙烯(PP塑料)是继尼龙之后发展的又一优良树脂品种，它是一种高密度、无侧链、高结晶必的线性聚合物，具有优良的综合性能。未着色时呈白色半透明，蜡状；比聚乙烯轻。透明度也较聚乙烯好，比聚乙烯刚硬。名称中文名　　（聚丙烯）[1]英文名称:　　Polypropylene编辑本段PP塑料概念比重：　　0.9-0.91克/立方厘米成型收缩率：　　⒈0-2.5%成型温度　　160-220℃干燥条件　　物料性能 密度小，强度刚度，硬度耐热性均优于低压聚乙烯，可在100度左右使用.具有良好的电性能和高频绝缘性不受湿度影响，但低温时变脆，不耐磨易老化. 适于制作一般机械零件，耐腐蚀零件和绝缘零件编辑本段成型性能　　⒈结晶料，吸湿性小，易发生融体破裂，长期与热金属接触易分解. 　　⒉流动性好，但收缩范围及收缩值大，易发生缩孔.凹痕，变形. 　　⒊冷却速度快，浇注系统及冷却系统应缓慢散热，并注意控制成型温度.料温低方向方向性明显.低温高压时尤其明显，模具温度低于50度时，塑件不光滑，易产生熔接不良，留痕，90度以上易发生翘曲变形 　　⒋塑料壁厚须均匀，避免缺胶，尖角，以防应力集中. 　　特定条件下容易分解 　　常见制品：盆、桶、家具、薄膜、编织袋、瓶盖、汽车保险杠等。 　　聚丙烯也包括丙烯与少量乙烯的共聚物在内。PP粒料为本色、圆柱状颗粒，颗粒光洁，粒子的尺寸在任意方向上为2mm～5mm，无臭无毒，无机械杂质。该品以高纯度丙烯为主要原料，乙烯为共聚单体，采用高活性催化剂在62℃～80℃及低于4.0MPa的压力下经气相反应生产聚丙烯粉料，再经干燥、混炼、挤压、造粒、筛分、均化成聚丙烯颗粒。密度为0.90 g/cm3～0.91g/cm3，是通用塑料中最轻的一种。聚丙烯树脂具有优良的机械性能和耐热性能，使用温度范围-30℃～140℃。同时具有优良的电绝缘性能和化学稳定性，几乎不吸水，与绝大多数化学品接触不发生作用。该品耐腐蚀，抗张强度30MPa，强度、刚性和透明性都比聚乙烯好；缺点是耐低温冲击性差，较易老化，但可分别通过改性和添加抗氧剂予以克服。与发烟硫酸、发烟硝酸、铬酸溶液、卤素、苯、四氯化碳、氯仿等接触有腐蚀作用。可用作工程塑料，适用于制电视机、收音机外壳、电器绝缘材料、防腐管道、板材、贮槽等，也用于生产扁丝、纤维、包装薄膜等。编辑本段典型应用范围汽车工业　　（主要使用含金属添加剂的PP：挡泥板、通风管、风扇等），器械（洗碗机门衬垫、干燥机通风管、洗衣机框架及机盖、冰箱门衬垫等），日用消费品（草坪和园艺设备如 　　剪草机和喷水器等）。 　　注塑模工艺条件：干燥处理　　如果储存适当则不需要干燥处理。熔化温度　　220~275℃，注意不要超过275℃。模具温度　　40~80℃，建议使用50℃。结晶程度主要由模具温度决定。注射压力　　可大到1800bar。注射速度　　通常，使用高速注塑可以使内部压力减小到最小。如果制品表面出现了缺陷，那么应使用较高温度下的低速注塑。流道和浇口　　对于冷流道，典型的流道直径范围是4~7mm。建议使用通体为圆形的注入口和流道。所有类型的浇口都可以使用。典型的浇口直径范围是1~1.5mm，但也可以使用小到0.7mm的浇口。对于边缘浇口，最小的浇口深度应为壁厚的一半；最小的浇口宽度应至少为壁厚的两倍。PP材料完全可以使用热流道系统。编辑本段化学和物理特性　　PP是一种半结晶性材料。它比PE要更坚硬并且有更高的熔点。由于均聚物型的PP温度高于0℃以上时非常脆，因此许多商业的PP材料是加入1~4%乙烯的无规则共聚物或更高比率乙烯含量的钳段式共聚物。共聚物型的PP材料有较低的热扭曲温度（100℃）、更高的透明度、低光泽度、低刚性，但是有有更强的抗冲击强度。PP的冲击强度随着乙烯含量的增加而增大。PP的维卡软化温度为150℃。由于结晶度较高，这种材料的表面刚度和抗划痕特性很好。PP不存在环境应力开裂问题。通常，采用加入玻璃纤维、金属添加剂或热塑橡胶的方法对PP进行改性。PP的流动率MFR范围在1~40。低MFR的PP材料抗冲击特性较好但延展强度较低。对于相同MFR的材料，共聚物型的冲击强度比均聚物型的要高。由于结晶，PP的收缩率相当高，一般为1.8~2.5%。并且收缩率的方向均匀性比PE-HD等材料要好得多。加入30%的玻璃添加剂可以使收缩率降到0.7%。均聚物型和共聚物型的PP材料都具有优良的抗吸湿性、抗酸碱腐蚀性、抗溶解性。然而，它对芳香烃（如苯）溶剂、氯化烃（四氯化碳）溶剂等没有抵抗力。PP也不象PE那样在高温下仍具有抗氧化性。编辑本段简易识别密度　　密度为0.91 g/cm3～0.96g/cm3。可燃性　　容易熔融滴落，火焰上黄下蓝，离火继续燃烧，燃烧后散发出石油味。可溶性　　可溶于对二甲苯，不溶于丙酮和乙醚。

一、前言水火箭是以力学能推进。水火箭的操作原理主要以牛顿第三定律(作用力和反作用力定律)为主，当高压水柱由压力槽激发出来时，强大的推力(反作用力)会将整个箭身往上带，火箭就飞起来了。其实水火箭的基本原理就和真正的火箭载具一样，只是推动的燃料是水和高压空气，所以我们还需考虑到基本的气体动力学和流体力学。 二、理论说明水火箭的发射步骤最重要的就是装水和打气。这两个动作都是有理论基础的，以下就是这两个动作背后的理论说明：装水 —水火箭在发射前要先装水，水量大概介於压力槽全部容量的三分之一到二分之一间。就像真正的火箭一样，水就是水火箭的燃料，是用来当推进动力的，与真正的火箭不同的是火箭燃料是释放化学能，而水火箭则是释放力学能，所以装水是加入水火箭发射时所需的燃料。 打气 —接下来要用打气筒连接水火箭打气。当你在打气时，你的手正在对空气分子做功，空气分子带有能量，慢慢地累积在水火箭的压力槽里，就变成了发射的动力来源—也就是力学能。 三、发射用具由於水火箭的推力是由高压空气和水所提供，所以我们需要一些能抗高压的塑胶材料来发射水火箭，一般所需要的用具有连接器、喷嘴、弹头、打气筒、压力计和发射架。以下是它们的基本介绍： 1. 连接器–由四分接头与打气风嘴组合而成，发射时卡住喷嘴以利释放，优点是可以随意控制发射时间及压力。打气时，打气筒连接打气风嘴，发射时，用手迅速下拉连接器，箭体就发射出去了。 2. 喷嘴–水火箭最重要的零件，需要绝对抗高压的塑材，一般自制的喷嘴是以碳酸汽水瓶盖和双向接头黏合而成，另外还有品质较好的日本制品。 3. 弹头–弹头需要较小的阻力，又能抵消冲击力的塑材。 4. 打气筒– 脚踏车的打气筒，最好是用手打气，而不要用较脆弱的脚踩式打气筒。 5. 压力计– 用来测量打气筒与水火箭压力槽的压力，通常是装置在打气筒上，使之与打气筒、压力槽连通。 6. 发射架 四、发射程序装置发射架 → 加入适量的水 → 将喷嘴旋上 → 以连接器卡住喷嘴并 将打气筒连上打气喷嘴 → 开始打气 (通常单槽水火箭的压力大约7大气压 、双嘈则打到一百下左右) → 松开打气筒 → 倒数计时 → 下拉保险发射
