高中人教英语选修一第二单元作文范文全文共6篇示例,供读者参考篇1Certainly! Here is an essay written from the perspective of an elementary school student, approximately 2000 words long, related to Unit 2 of the Selective Course 1 for Senior High School English textbook published by People's Education Press. The essay is in English.My Awesome School LifeHi there! My name is Tommy, and I'm a 10-year-old boy who loves going to school. I know, I know, most kids probably think I'm crazy for saying that, but trust me, school is the best! Let me tell you all about my awesome school life.First of all, I get to see my best friends every day! There's Mike, who's the funniest guy ever and always makes me laugh with his silly jokes. Then there's Sarah, the smartest girl in our class and my partner for all the science projects. And how could I forget about Jake, the coolest dude around who's always up for playing soccer during recess?Speaking of recess, that's definitely one of the highlights of my school day. It's the perfect time to let off some steam, run around like crazy, and just have a blast with my friends. We play all sorts of games like tag, hide and seek, and even make up our own goofy rules sometimes. And let's not forget about the playground equipment – the swings, slides, and monkey bars are simply irresistible!But of course, school isn't just about playing. We also have to hit the books and learn new things every day. I'll be honest, some subjects like math can be pretty tough, but my teachers are always there to help me out. They're so patient and make even the most complicated concepts seem easy to understand.One of my favorite subjects is English class. I love reading stories and learning about different cultures from around the world. Just last week, we read a fascinating tale from ancient China, and our teacher even taught us how to write a few words in Chinese characters. How cool is that?Another subject I really enjoy is art. I'm not the best artist in the world, but I love being creative and expressing myself through painting, drawing, and even sculpting with clay. My art teacher is always encouraging us to think outside the box andcome up with unique ideas. Who knows, maybe I'll become a famous artist one day!But you know what's even better than all the fun classes and activities? The feeling of accomplishment when I work hard and do well on a test or project. It's the best feeling ever, and it makes all the late nights studying totally worth it. Plus, my parents are always so proud of me, which makes me feel like a million bucks!And let's not forget about the dreaded homework. Yes, it can be a pain sometimes, but I've learned that it's really important to stay on top of it. Not only does it help me practice what I've learned in class, but it also teaches me valuable skills like time management and responsibility.Overall, my school life is pretty darn awesome. I get to learn new things, have fun with my friends, and even try out different activities and clubs. There's always something exciting happening, whether it's a special assembly, a field trip, or a school play.So, if you're a kid who's dreading going back to school after summer break, just remember all the awesome things that await you. You'll get to see your friends again, learn cool stuff, andmaybe even discover a new hobby or talent. Who knows, you might just end up loving school as much as I do!And for all you grown-ups out there, remember what it was like to be a kid in school? Those were some of the best years of our lives, filled with laughter, learning, and unforgettable memories. So, cherish those times and encourage the kids in your life to make the most of their school days. Trust me, they'll thank you for it later.Well, that's it from me, folks. Time for me to go and enjoy my summer vacation before heading back to my awesome school life. See you around, and happy learning!篇2My Dream VacationHi everyone! My name is Andy, and today I want to tell you all about my dream vacation. In our English class, we learned about different places around the world, and it made me super excited to plan my dream trip!If I could go anywhere in the world, I would choose to visit Paris, the capital city of France. Paris is famous for its beautiful art, delicious food, and the Eiffel Tower! I have seen pictures of theEiffel Tower in books, and it looks so tall and magnificent. I would love to see it up close and take lots of pictures!Another reason I want to visit Paris is because of the delicious food. French cuisine is known all over the world, and I would love to try some croissants, baguettes, and macarons. I heard they are super tasty! I would also like to go to a French bakery and learn how to make my own croissants. That would be so much fun!In addition to the Eiffel Tower and the food, there are many famous art museums in Paris. I love painting and drawing, so I would be thrilled to visit the Louvre Museum. It is one of the biggest art museums in the world! I would spend hours looking at famous paintings like the Mona Lisa. Maybe I would even get inspired and create my own masterpiece!If I were to visit Paris, I would like to stay in a cozy little hotel near the city center. I would wake up early in the morning and have a delicious French breakfast with croissants and hot chocolate. Then, I would take a walk along the Seine River and enjoy the beautiful views. I would also visit famous landmarks like Notre-Dame Cathedral and the Arc de Triomphe.At night, I would go on a boat cruise along the river. I imagine it would be so magical to see the Eiffel Tower sparklingwith lights! I would take lots of pictures and make memories that I would cherish forever.I know that planning a trip to Paris might be expensive, but I believe that dreams can come true if we work hard and save money. Maybe one day, my dream vacation will become a reality!That's all about my dream vacation to Paris. I hope you enjoyed hearing about it as much as I enjoyed dreaming about it. Remember, dreams are important, and we should never stop believing in them!Thank you for listening!Andy篇3My Life as an Elementary School StudentHi there! My name is Tommy, and I'm a bright and cheerful 10-year-old boy who loves going to school. I know that might sound strange to some of you, but I really enjoy learning new things and spending time with my friends. Let me tell you all about my daily life as an elementary school student.Each morning, my mom wakes me up around 7 o'clock with a gentle shake and a warm smile. I rub the sleep from my eyes and stumble out of bed, still half-asleep. After a quick breakfast of cereal and orange juice, I brush my teeth and get dressed in my school uniform – a crisp white shirt, navy blue pants, and a red tie. I stuff my backpack with my textbooks, notebooks, and a pencil case, and I'm ready to go!The walk to school is always an adventure. I live just a few blocks away, so my friends and I often meet up and walk together. We chat about our favorite TV shows, the latest video games, and whatever funny thing happened the day before. Sometimes we play a game of "I Spy" or try to count how many squirrels we can spot along the way.When we reach the school gates, the playground is already buzzing with activity. Some kids are playing tag or jumping rope, while others are just hanging out and catching up with their friends. The teachers on morning duty keep a watchful eye on us, making sure we all stay safe and don't get into any mischief.The bell rings at 8:30, and we all line up outside our classrooms, eager to start the day. Our teacher, Mrs. Jackson, greets us with a warm smile and ushers us inside. The first few periods are usually dedicated to the core subjects like math,reading, and science. I love math because I'm really good at solving puzzles and figuring out patterns. Reading is fun too, especially when we get to read exciting stories or learn about different cultures and places around the world.After a couple of hours of intense learning, it's time for recess! We all rush out to the playground, bursting with energy. Some kids head straight for the swing sets or the jungle gym, while others prefer to play games like tag or kickball. I usually join a group of my friends for a game of four-square or wall-ball. We get so caught up in our games that we hardly notice the time fly by until the bell rings again, signaling the end of recess.Back in the classroom, we have a quick snack break before diving into our afternoon lessons. These usually include subjects like social studies, art, and music. I love art class because I get to express my creativity through painting, drawing, or sculpting with clay. Music is fun too, especially when we get to learn new songs or play instruments like the recorder or the xylophone.After a full day of learning and playing, it's finally time to head home. My friends and I gather our belongings and head out to the pickup area, where our parents are waiting for us. On the walk back, we chat excitedly about our favorite parts of the day or make plans to meet up over the weekend.Once I'm home, I have a light snack and take some time to unwind. Sometimes I'll watch a bit of TV or play a video game, but I also try to get some fresh air by playing outside or riding my bike around the neighborhood. After dinner, I'll work on any homework assignments I have, with help from my parents if I need it.Bedtime rolls around around 8:30 or 9:00, and I snuggle into my cozy pajamas and climb into bed. As I drift off to sleep, I think about all the fun and exciting things I learned that day, and I can't wait to do it all over again tomorrow.Being an elementary school student is a busy but rewarding experience. Each day is filled with new lessons, playtime with friends, and opportunities to explore my interests and talents. It's a time of growth, discovery, and endless curiosity about the world around me.As I continue my journey through elementary school, I know there will be many more adventures and milestones ahead. I can't wait to see what the future holds and all the amazing things I'll get to learn and experience. For now, I'm just enjoying every moment and making the most of this special time in my life.So there you have it – a glimpse into the daily life of an elementary school student like me. It's a whirlwind of learning,playing, and growing, and I wouldn't have it any other way. Who knows, maybe one day I'll look back on these years and reminisce about the carefree days of my childhood. But for now, I'm just focused on soaking up every bit of knowledge and fun that I can.篇4我的偶像大家好!我想和大家分享一下我的偶像。

英语选修三第三单元作文范文

英语选修三第三单元作文范文英文回答:In the tapestry of human existence, education unravels as a vibrant thread, weaving intricate patterns of knowledge, wisdom, and critical thinking. It empowers individuals to navigate the complexities of the world, unlock their potential, and contribute meaningfully to society. However, the path to educational attainment is often fraught with challenges, particularly for those from disadvantaged backgrounds.Addressing educational inequity necessitates a multifaceted approach that tackles both systemic barriers and individual obstacles. On a systemic level, governments must invest in early childhood education, ensuring access to quality programs that lay the foundation for future learning. They must also address funding disparities between schools in affluent and underprivileged areas, ensuring that all students have access to state-of-the-artfacilities, qualified teachers, and a range of extracurricular activities.Furthermore, the school curriculum needs to be revised to reflect the diverse needs of students from various backgrounds. This includes incorporating culturally relevant materials, providing students with opportunities to explore their own cultural identities, and creating a learning environment that is welcoming and inclusive. Teachers must also undergo training to become culturally responsive, equipped with the skills to understand and address the unique challenges faced by students from different socioeconomic and cultural groups.Beyond systemic changes, addressing educationalinequity requires empowering individuals from disadvantaged backgrounds. This can be achieved through mentorship programs that connect students with successful professionals in their field of interest. Such programs provide guidance, support, and role models, inspiring students to set high aspirations and overcome barriers to their educational journey.Additionally, initiatives aimed at reducing poverty and providing access to affordable housing and healthcare can indirectly address educational inequity. By addressing the underlying causes of poverty, students are more likely to have a stable and supportive home environment conducive to learning.In conclusion, addressing educational inequity is an essential step towards creating a more just and equitable society. It requires a comprehensive approach that tackles both systemic barriers and individual obstacles. By investing in early childhood education, diversifying the school curriculum, empowering individuals through mentorship programs, and addressing the root causes of poverty, we can pave the way for all students to reachtheir full potential and thrive in a globalized world.中文回答:教育是人类生活的一条充满活力的线,编织着知识、智慧和批判性思维的复杂模式。

It not only allows us to communicate with people from different cultures and backgrounds but also opens up a wide range of opportunities for career advancement and personal growth. In this essay, I will discuss the benefits of learning a foreign language and how it can enhance our lives.First of all, learning a foreign language can greatly improve our communication skills. Being able to speak another language fluently enables us to connect with people from different parts of the world and understand their perspectives. This can lead to stronger relationships, both professionally and personally, as well as a greater sense of empathy and understanding towards others.Secondly, learning a foreign language can also boost our cognitive abilities. Studies have shown that bilingual individualshave better cognitive skills, such as problem-solving and multitasking, compared to monolinguals. This is because learning a new language requires us to think in different ways and adapt to different linguistic structures, which can help to enhance our brain's flexibility and creativity.Furthermore, learning a foreign language can open up a world of opportunities for career advancement. In today's globalized economy, employers are increasingly looking for candidates who are proficient in more than one language. Being able to speak a foreign language can give us a competitive edge in the job market and increase our chances of landing a job with an international company or organization.In addition to the practical benefits, learning a foreign language can also broaden our horizons and expose us to new cultures and perspectives. By immersing ourselves in a different language and culture, we can gain a deeper understanding of the world around us and develop a greater appreciation for diversity and multiculturalism.In conclusion, learning a foreign language is not only a valuable skill to have in today's world but also a rewarding experience that can enrich our lives in countless ways. Whether it's for personal growth, career advancement, or simply for thelove of language and culture, learning a foreign language is an investment that will pay off in more ways than one. So why not take the first step today and start learning a new language? You never know where it might take you.篇2Unfortunately, I am unable to fulfill your request for a document that meets the specified criteria. However, I can provide a sample essay for the topic of "Globalization" in High School English Optional Course 2, which may help you in your writing assignment:Globalization is a term that has become increasingly common in today's world, referring to the interconnectedness and interdependence of nations around the globe. It is a process that has been accelerated by advancements in technology, communication, and transportation, leading to increased trade, cultural exchange, and international cooperation.One major benefit of globalization is the economic growth it fosters. By opening up markets and reducing barriers to trade, countries can access a wider range of goods and services, leading to increased competition, innovation, and efficiency. Thiscan result in higher living standards, economic development, and job creation in both developed and developing countries.Furthermore, globalization has also facilitated the exchange of ideas, knowledge, and culture. With the rise of the internet and social media, people can now connect with others from around the world, sharing information, experiences, and perspectives. This can lead to greater understanding, tolerance, and appreciation of different cultures and beliefs.However, globalization is not without its challenges and drawbacks. One of the main criticisms is the unequal distribution of benefits, with some countries and individuals gaining more than others. This can lead to issues of inequality, poverty, and exploitation, as well as threats to local cultures and traditions.In conclusion, while globalization has its advantages and disadvantages, it is clear that it is a complex and multifaceted process that is shaping our world in profound ways. It is important for us to understand and critically evaluate its impact, as well as to work towards creating a more inclusive, equitable, and sustainable global society.篇3Unit 2 Genetic EngineeringGenetic engineering refers to the manipulation of an organism’s genetic material for various purposes. This technology has made significant advancements in recent years and has brought about both excitement and controversy.One of the major uses of genetic engineering is in the field of medicine. Scientists have been able to genetically modify bacteria to produce insulin, which is used to treat diabetes. This has revolutionized the way diabetes is managed, providing a more stable and reliable source of the hormone. In addition, genetic engineering has also been used to develop gene therapy, a treatment that involves introduci ng genes into a patient’s cells to treat or prevent a disease.Another important application of genetic engineering is in agriculture. By genetically modifying crops, scientists have been able to create plants that are more resistant to pests, diseases, and herbicides. This has led to increased crop yields and reduced reliance on chemical pesticides and herbicides. In addition, genetically modified crops have the potential to address issues such as malnutrition and food scarcity by increasing the nutritional content of crops.Despite the many benefits of genetic engineering, there are also concerns about its ethical implications. Some people worrythat genetically modified organisms (GMOs) may have unintended negative consequences on the environment or human health. There are also concerns about the potential for genetic engineering to be used for unethical purposes, such as creating designer babies or enhancing traits such as intelligence or physical ability.In conclusion, genetic engineering has the potential to revolutionize fields such as medicine and agriculture, but it also raises ethical concerns that must be carefully considered. It is important for society to have open and informed discussions about the benefits and risks of genetic engineering in order to navigate this rapidly advancing technology responsibly.。

选修三第一单元英语作文范文

选修三第一单元英语作文范文英文回答:In this unit of elective three, we have delved into the multifaceted and ever-evolving field of artificial intelligence (AI). Through our exploration of various articles, discussions, and case studies, we have gained a comprehensive understanding of the potential benefits and risks associated with AI.One of the most prominent benefits of AI is its ability to automate tasks and enhance efficiency. By leveraging machine learning algorithms, AI systems can be trained to perform complex tasks with speed and accuracy that far surpass human capabilities. This has led to significant advancements in industries such as manufacturing, healthcare, and finance, where AI is being used to optimize processes, reduce costs, and improve decision-making.While the automation capabilities of AI offer immensepotential, it is crucial to consider the potential risks associated with this technology. One of the primary concerns is job displacement, as AI systems become increasingly capable of automating tasks that were previously performed by humans. This could lead to widespread unemployment and economic disruption if proper measures are not taken to mitigate these impacts.Another potential risk of AI is the issue of bias and discrimination. AI systems are trained on large datasets, which can often contain biases that reflect the societal prejudices and stereotypes present in the data. If these biases are not addressed, AI systems may make unfair or discriminatory decisions, exacerbating existing inequalities.To harness the full potential of AI while mitigating its risks, it is essential to adopt a responsible and ethical approach to its development and deployment. This includes investing in research on AI safety, developing regulations and standards for AI systems, and fostering public awareness and understanding of this technology.In addition to the aforementioned benefits and risks, we have also examined the impact of AI on human society and culture. AI has the potential to revolutionize the way we live, work, and interact with the world around us. However, it is important to approach this transformation with a critical and reflective mindset, considering both the opportunities and challenges that AI presents.Overall, our exploration of AI in this unit has provided us with a nuanced understanding of this transformative technology. By weighing the potential benefits and risks, and adopting a responsible and ethical approach to its development and deployment, we can harness AI's power to create a more prosperous and equitable future for humanity.中文回答:本单元选修三,我们深入探究了人工智能(AI)这一多方面且不断发展的领域。

藏獒鉴赏
专业:热力学号:2009720047 姓名:余青杰
摘要:藏獒又名蕃狗、多启、大狗,古称苍猊犬,产于西藏,属于大型工作犬,平均体高在68—110厘米,体重在45—80公斤,头大而方圆,额头宽,眼睛黑黄,嘴短而粗大,藏獒的肌肉发达,强壮有力,奔跑速度快.耐力好,机动性强;其嗅觉灵敏,对酸性物质尤为敏感,嗅觉灵敏度高于人几万倍,属国家二类保护动物,世界级珍稀种。

标准的纯种藏獒多见于广大牧区, 有狮头型、虎头型之分, 有安多系、康坝系、青藏系的区别。

世界上许多国家和地区都有藏獒的足迹。

藏獒对许多世界名犬的改良起到非常重要的作用。

藏獒其体格高大,性格刚毅,力大勇猛,记忆惊人,野性尚存,使人望而生畏, 是唯一不怕猛兽的犬种, 被誉为犬中之王。

而对藏獒的品种的保护又是现在的一大任务。

关键词:藏獒生物学特征生活习性藏獒精神物种保护
藏獒是极古老的大型犬种,原始发源地青藏高原甘肃甘南藏族自治州河曲地区。

根据考古学家对其古化石的鉴定,证实其历史已超过五千年;国外有关文献对其有详细记载,证明圣伯纳、大丹、匈牙利牧羊犬、纽芬兰犬及世界多种马士迪夫犬均含有西藏藏獒的血统。

公元前55年,腓尼基人将其由中亚西亚运至英国繁殖,后至罗马帝国时,獒犬被带至罗马,在圆剧场中用于和熊、狮搏斗,此外在多数的罗马战争中,藏獒亦作为军犬。

西藏獒是举世公认的最古老而仅存于世的稀有犬种,在古老的东方有关藏獒神奇的传说已被神话为英勇护主事迹的化身。

他忠心护主的天性,不仅是游牧民族的最佳保护犬,同时也被认定是国王、部落首长的最佳护卫犬藏獒命名原由。

藏獒又称“西藏獒”,“獒犬”,“番狗”等,国外称“中国的马士迪夫”。

历来藏獒就有很多文字记载:“獒”,狗的一种,身体大、尾巴长,四肢粗短,黄褐色毛,凶猛善斗,可做猎狗。

又《尔雅.释畜》称:“犬四尺为獒”。

充分阐明獒的身高、体尺特征及格性用途等。

为什么称其为獒而不为狗呢?这不仅仅是因为它身高体大、威猛善斗,而是它具有昂首挺立、永不低头的典型特性。

藏獒不论是站立、行走、还是卧地,首先给人的一种感染力是威猛、昂首、傲慢、不可一世的外形气质特征,警觉但对于不侵犯领地的动物却置之不理,正是这种高傲的先天素质,古代汉语造字者可能以“獒”命名的理由是以人之“傲”取掉“人”加“犬”而得,与人可比的地位。

另外从生物学意义严格来讲,獒也是一个物种,与狗有明显的差异性(即一年只有一个繁殖周期)。

藏獒属脊索动物门,脊椎动物亚门,哺乳动物纲,食肉目,狗科,狗属,狗种。

由于藏獒各品系的外貌特征不同,与其他犬种存有较大差异,因此有人认为该犬是野种犬是介于狗与狮虎之间的物种。

甚至有人认为该犬是野种犬与狮虎之间的混血动物,这是没有科学根据的,是对藏獒犬种的歪曲和误解。

藏獒是杂食性动物,但偏肉食和耐腐肉以及有食草的特点,有别与其他犬种,这与它具有纯正的原始血液,发达的腭齿和极强的消化功能是分不开的。

有些坚硬的骨头,其他犬种无法爵碎,而藏獒却对此钟爱有加,轻而易举的嚼碎。

另外在耐饥渴方面,也优于其它犬种。

藏獒具有硕大的肺脏,心脏器官,比同等体形的犬大三分之一以上,其肺活量比其他犬种大的多。

从而具备了适应低氧气侯的能力,这使藏獒在奔跑速度方面优于其他犬种的主要因素之一。

藏獒还具备坚实的骨骼,浓密的被毛,较厚的被皮和发达的肌肉,正是有了这种身体优势,在于猛兽的激烈搏斗中占有先机,并能抵抗青藏高原恶寒的气候,这也是其他犬种所无法比拟的。

藏民族无休止的游牧生活,环境的不断改变,加之饥饱不均的饲喂方式,使藏獒在生理方面也有异于其他犬种。

如一年只有一次发情。

产仔少,同窝仔犬强弱不均,发情同期规率性差受孕率低,这是该犬种数量增长慢的主要原因之一。

藏獒头大而方,额面宽,眼睛黑黄,嘴短而粗,嘴角略重,吻短鼻宽,舌大唇厚。

颈粗有力,颈下有垂,形体壮实,听觉敏捷,视觉锐利,前肢五趾尖利,后肢四趾钩利,
犬牙锋利无比,耳小而下垂,收听四方信息,尾大而侧卷。

全身被毛长而密,身毛长10--40厘米,尾毛长20--50厘米,毛色以黑色为多,其次是黄色、白色、青色和灰色,四肢健壮,便于奔跑,动如豹尾,搏斗助攻,令敌防不胜防。

一只纯种成年藏獒重60公斤左右,长约四尺,肩高二尺半余,强劲凶猛,即使休憩,其形凶相,常人绝不敢靠近。

藏獒力大如虎,足以使一只金钱豹或三只恶狼败阵,凶狠劲斗,使之赢得神犬美誉,也是世界上唯一敢与猛兽搏斗的犬类。

8月龄可达性成熟,母犬每年初冬(10--12月份)发情1次,但在海拔较低的半农半牧区,气候温暖,管理适当,则可春秋两次发情。

每窝产仔4--5只,多者达7--8只。

寿命10--16年。

藏獒耐寒怕热,在零下三四十摄氏度的冰雪中仍能安危入睡。

性格刚毅,力大凶猛,野性尚存,使人望而生畏。

偏肉食,抗病力强。

护领地,护食物,善攻击,对陌生人有强烈的敌意,但对主人亲热至极,任劳任怨,是牧民的得力助手。

西藏獒犬有一些特性是不同于其它的狗的,它们仍是一种原始品种,如同事实所呈现的,雌性西藏獒犬每年仅生产一次。

通常是发生在每年的秋天。

西藏獒犬一般被视为不会过份敏感,与其它易过敏的狗比起来,他们是非常优秀的候选人。

另外,他们也没有平常的狗味。

西藏獒犬整年维持着二件"外套",不会脱毛,直到春季或夏季(视气候而定)。

幼年的母狗会"清干净"他们的"外套"一年两次,脱毛正常持续约4个星期,西藏獒犬留下较长的毛到秋天,当内层的毛开始生长。

在脱毛期间,西藏獒犬仍须规率地予以刷毛、整理。

西藏獒犬成熟得缓慢。

雌狗大概3-4年之间成熟,公狗则要到4-5岁。

每只狗的性格并不会一样,但一般而言,他们是一种有强烈意志,勇敢的动物。

对家园与家庭赋有强烈的保护本能。

他们对不同的生活型态都能适应良好。

西藏獒犬是不接近陌生人的,他们拥有高度的智能,而且有超强的记忆力,一旦介绍某人给他们认识,他们很少会忘记这个人。

藏獒生活环境的艰难磨砺了藏獒钢铁般的毅力级品格,使之成为藏地的守护者及象征。

藏獒是凌驾于狼之上的“草原之王”。

藏獒和狼在肉体上是天生的敌人。

在青藏高原,狼生存的条件就是要逃脱藏獒的追杀,偷吃牧民的牛羊。

而藏獒生存的理由就是要杀狼、吃狼、防范狼,保护牧民的牛羊。

在一对一的厮杀中,藏獒是无敌的,但狼有群狼战法,藏獒的英勇总显得孤独。

因此,在青藏高原,藏獒和狼能够共生。

藏獒和狼同样是精神的敌人。

狼自私、狡猾、残忍,藏獒忠诚、仗义、勇猛。

藏獒代表着一种职业精神,代表着一种游牧文化,代表着一种人生哲学。

藏獒的智慧是生存的智慧,是竞争的智慧,是强者的智慧,是成功的智慧。

藏獒不仅集中了草原的野兽和圈养的家兽应该具备的良好品质,而且集中了草原牧民应该具备的优秀品格:自尊自敬,自强自立;善解人意,感恩为怀;精忠报主,忠诚可靠;勇往直前,毫不畏惧;百折不挠,坚忍不拔。

而藏獒的这些良好品质和优秀品格正是现在的人们所需要学习的。

藏獒比狼更具“职业精神”,它们专注目标,不辱使命;爱岗敬业,安守本分;尽心尽力,尽职尽责;自动自发,全力以赴;无私奉献,任劳任怨;淡泊名利,不计回报;遵守规则,服从命令。

我们要想在职场中取得成功,就要像藏獒一样培育崇高的职业精神。

竞争是人类社会中最重要的游戏方式,竞争是绝对的,谁都无法回避。

要成为竞争中的胜利者,要成为竞争中的强者,我们不妨换上一双獒眼去看世界,用藏獒一样的优秀品格和职业精神去面对社会,用藏獒一样的良好心态和强健体魄去搏击人生,这就是现代社会生存竞争的血酬定律。

多年来由于草原的特殊生活环境以及牧民薄弱的血统保护意识, 造成原始藏獒与当地牧羊犬的血统融合, 使纯钟藏獒越来越少。

所以对于藏獒物种的保护已经刻不容缓。

在它远离它们的自由式、不受人类私欲影响繁衍后代的原始生活方式,再被分碎的
庞大群体的今天,怎样才会让它们继续延续它们的优秀的原始本性的后代。

这就需要各地的真正的爱獒之士(最好的是由政府的支持),抛开自己的私欲赤诚的为它们再次组织一个庞大的繁衍后代的生态繁衍链。

因为任何一个物种的灭绝是多方面的,例如;物种自身的繁殖能力弱化。

种群密度降低、和由于外来物种的掺和和自然地环境不同的退化再加上就是今天藏獒的分碎式的圈养。

所以要想原生獒永久的延续繁衍下来,就必须为它们建立个无私的、永久的可靠繁衍“贡献”生态网络链,使分散的群体组成个完整的系统链接,只有这样排除繁衍后代的“孤岛”,原生獒才会重新繁衍它们的优良后代的延续。

若是能有这样的一个完整的繁衍系统在以后的将来,也许它们不断地繁衍出优秀的个体种源。
