1、善本，最早是指校勘严密、刻印精美的古籍，后含义渐广，包括刻印较早、流传较少的各类古籍。实际上，真正的善本仍应主要着眼于书的内容，着眼于古籍的科学研究价值和历史文物价值。

2、最早出现善本概念是宋代，是指版刻书籍的精品。善就是好的意思，“善本”的原始内涵指那些版刻古籍中的校刊好、装帧好，时代久、流传少，具有学术价值和历史价值的书籍。版刻书籍是用木版雕刻文字印刷成书，唐以前没有发明印刷术，用刀笔刻写笔刻在竹简、缣帛、纸和羊皮上。

3、唐发明了模印法后，宋的雕版印刷已经非常发达，书籍发行量大增。印书分官刻和民刻，官刻是由朝廷经办的，质量好。民间作坊质量参差不齐，装帧、脱字、讹字、纸张、字迹等存在种种问题。宋代是版刻鼎盛时期，于是出现了对善本和不善本的研究。

4、不同版本书籍收录文献多寡、校勘精劣程度各不相同，就有了足本和残本、精本和劣本的差别；书籍版本出现早晚、珍稀程度不同，就有了古本和今本、孤本和复本的差别。善本的内涵也比原来更扩大了，以后许多学者对善本的概念不断总结归纳，最后形成了现在通用的善本“三性”、“九条”说。

5、善本的时代下限，现在一般确定在清乾隆六十年（公元1795年）。

以下是三篇以《为什么要保护动物》为题的英语作文，供大家参考。❤

第一篇英语作文

写作思路：

本文将从人类与动物的关系、生态平衡和道德责任三个方面来探讨为什么要保护动物。

正文：

Why Protect Animals

Animals are an important part of our world They provide us with food, clothing, and even companionship However, the relationship between humans and animals is not always positive Many animals are hunted or mistreated for human benefit This can upset the delicate balance of our ecosystem and harm our planet as a whole Therefore, it is our moral responsibility to protect animals

Firstly, animals play an important role in maintaining ecological balance Each species has its unique place in the food chain If one species disappears, it can affect the entire ecosystem For example, if bees were to become extinct, it would have a devastating impact on agriculture because they are responsible for pollination Therefore, protecting animals helps to preserve the natural environment and prevent ecological disasters

Secondly, we have a moral obligation to treat animals with respect and compassion They are sentient beings that can feel pain and suffer just like humans It is cruel to cause unnecessary harm to them for our own selfish desires We should strive to minimize animal cruelty by promoting responsible pet ownership, reducing the consumption of animal products, and supporting animal welfare organizations

In conclusion, protecting animals is crucial for maintaining ecological balance and fulfilling our moral responsibility towards other living beings Let us all work together to create a world where humans and animals can coexist in harmony

难词解释：

Ecosystem（生态系统）是指由相互作用的生物和它们的物理环境组成的生物群落。

Devastating（毁灭性的）是指造成巨大破坏或毁灭的。

Sentient（有感觉的）是指能够感知或感受事物的。

翻译：

为什么要保护动物？

动物是我们世界的重要组成部分。它们为我们提供食物、衣服，甚至陪伴。然而，人类与动物之间的关系并不总是积极的。许多动物为了人类的利益而被猎杀或虐待。这可能会破坏我们生态系统的微妙平衡，危害整个地球。因此，保护动物是我们的道德责任。

首先，动物在维持生态平衡方面发挥着重要作用。每个物种都有其在食物链中独特的位置。如果一个物种消失了，它会影响整个生态系统。例如，如果蜜蜂灭绝，它将对农业产生毁灭性影响，因为它们负责授粉。因此，保护动物有助于保护自然环境，预防生态灾难。

其次，我们有道德义务以尊重和同情的态度对待动物。它们是有感觉的生命体，能像人类一样感受到痛苦和苦难。为了满足我们自己的自私欲望而对它们造成不必要的伤害是残忍的。我们应该通过促进负责任的宠物主人、减少动物产品的消费和支持动物福利组织来努力减少虐待动物。

总之，保护动物对于维持生态平衡和履行我们对其他生命体的道德责任至关重要。让我们一起努力创造一个人类和动物可以和谐共处的世界。

第二篇英语作文

写作思路：

本篇作文将从环保、生态平衡和人道主义三个方面来阐述为什么要保护动物。

正文：

Why We Should Protect Animals

Animals are an important part of our world They play a crucial role in maintaining the balance of our ecosystem However, many species are endangered due to human activities such as hunting, poaching and habitat destruction It is important that we take action to protect these animals

Firstly, protecting animals is essential for environmental conservation Each species plays a unique role in the ecosystem For example, bees are responsible for pollinating plants, which helps to maintain plant diversity If bees were to disappear, it would have a significant impact on our food supply, as well as the health of our environment

Secondly, protecting animals is necessary for maintaining ecological balance When one species disappears, it can have a ripple effect on other species in the food chain This can lead to imbalances and disruptions in the ecosystem For instance, if predators like lions were to become extinct, herbivores like deer would overpopulate, leading to overgrazing and soil erosion

Lastly, protecting animals is a matter of compassion and respect for life Animals have the right to live without fear of being hunted or exploited by humans They are sentient beings that feel pain and suffer just like we do It is our responsibility to ensure that they are treated with kindness and respect

In conclusion, protecting animals is vital for the health of our planet, the preservation of our ecosystem, and the promotion of compassion and respect for all living creatures

难词解释：

Endangered (adj) 濒危的，处于危险中的

Poaching (n) 偷猎，盗猎

Habitat destruction (n) 栖息地破坏

Ecosystem (n) 生态系统

Pollinating (v) 授粉，传粉

Herbivores (n) 食草动物

Overgrazing (n) 过度放牧

Sentient (adj) 有知觉的，有感情的

翻译：

为什么要保护动物

动物是我们世界的重要组成部分。它们在维护生态平衡方面发挥着至关重要的作用。然而，由于人类活动，如狩猎、偷猎和栖息地破坏等，许多物种正在濒危。因此，保护这些动物变得至关重要。

首先，保护动物对环境保护至关重要。每个物种在生态系统中都扮演着独特的角色。例如，蜜蜂负责授粉，有助于维持植物多样性。如果蜜蜂消失了，它将对我们的食品供应以及环境的健康产生重大影响。

其次，保护动物对于维护生态平衡是必要的。当一个物种消失时，它会对食物链中的其他物种产生连锁反应。这可能导致生态系统的不平衡和破坏。例如，如果像狮子这样的食肉动物灭绝了，那么像鹿这样的食草动物会过度繁殖，导致过度放牧和土壤侵蚀。

最后，保护动物是一种关爱生命、尊重生命的表现。动物有权利在没有被人类猎杀或剥削的情况下生存。它们是有知觉的生命体，感受到痛苦和苦难，就像我们一样。我们有责任确保它们得到善待和尊重。

总之，保护动物对于地球的健康、生态系统的保护以及促进对所有生物的关爱和尊重至关重要。

第三篇英语作文

写作思路：

在这篇英语作文中，我将阐述保护动物的重要性。我将从以下几个方面来说明：1）动物是生态系统的一部分，对维护生态平衡至关重要；2）许多动物已经濒临灭绝，需要我们的保护；3）保护动物也是保护人类自身的利益。

正文：

Why it is important to protect animals

Animals are an integral part of our ecosystem They play a crucial role in maintaining the ecological balance of our planet Unfortunately, many animal species are on the brink of extinction due to human activities such as deforestation, hunting, and pollution It is our responsibility to protect these animals and their habitats

There are several reasons why we should protect animals Firstly, animals are essential for the proper functioning of the food chain If one species disappears, it can have a domino effect on other species in the ecosystem For example, if bees were to go extinct, it would have a catastrophic impact on the pollination of plants which could lead to food shortages for humans

Secondly, many animal species have already become endangered or extinct due to human activities This loss of biodiversity can have serious consequences for the environment and for us For instance, the extinction of certain animal species can lead to the loss of natural resources and medicines that are derived from them

Lastly, protecting animals also means protecting ourselves Many animals provide us with essential resources such as food, clothing, and medicine By protecting them, we are ensuring the sustainability of these resources for future generations

In conclusion, protecting animals is not only important for their own sake but also for the health and well-being of our planet and ourselves It is our responsibility to take action to preserve the natural world and all its inhabitants

难词解释：

integral (adj) - 必要的或不可或缺的

ecological balance (n) - 生态平衡，指生态系统中不同生物之间的平衡状态

extinction (n) - 灭绝，指某个物种不再存在的状态

biodiversity (n) - 生物多样性，指特定生态系统中生物的种类和数量的多样性

sustainability (n) - 可持续性，指在不耗尽资源的情况下保持某种事物在一定水平上的能力

翻译：

为什么要保护动物

动物是我们生态系统的一部分。它们在维持我们星球的生态平衡方面发挥着至关重要的作用。不幸的是，由于人类活动如森林砍伐、捕猎和污染等，许多动物物种濒临灭绝。保护这些动物及其栖息地是我们的责任。

有几个原因说明了我们应该保护动物。首先，动物对于食物链的正常运转至关重要。如果一个物种消失了，它会对生态系统中的其他物种产生多米诺效应。例如，如果蜜蜂灭绝了，它会对植物的授粉产生灾难性影响，从而可能导致人类粮食短缺。

其次，许多动物物种已经因人类活动而濒临灭绝或已经灭绝。这种生物多样性的丧失可能对环境和我们产生严重后果。例如，某些动物物种的灭绝可能导致从它们那里获得的自然资源和药品的损失。

最后，保护动物也意味着保护我们自己。许多动物为我们提供了必要的资源，如食物、衣服和药品。通过保护它们，我们正在确保这些资源的可持续性，以供未来几代人使用。

总之，保护动物不仅对它们本身非常重要，而且对我们星球的健康和福祉也非常重要。我们有责任采取行动来保护自然界及其所有生物。

为什么我们要保护野生动物

Many animals are in danger of dying outAs is shown in the chart, we can see the number of animal species decreases faster and faster and this trend will continueFrom 1980 to 2010, at least 1 million animal species have disappearedWorse still, more and more wild animals are in great dangerIt is not a piece of sensational news; it is a fact, a harsh realityUnfortunately, we may not see these animals in the near future

很多动物频临灭绝的危险。图表显示，我们可以看到动物物种数量下降的速度越来越快，而且这种趋势将会持续下去。从1980年到2010年，至少有100万动物物种已经消失。更糟糕的是，越来越多的野生动物处于巨大的危险中。这不是一则耸人听闻的新闻，这是一个事实，一个残酷的事实。不幸的是，将来我们可能看不到这些动物了。

From the second picture, we can find some reasonsWhy is the number of animal species declining year by yearApparently animals have become victims of fashion industryAnimal skin has been used to make fashionable clothes and these clothes sell at a high priceSo some greedy people begin to kill animals in a large quantityThis irresponsible behavior not only breaks the balance of nature but also endangers the living environment of human beings

从第二幅图我们可以找到一些原因。为什么动物物种的数量一年年的减少呢显然，动物成为了时尚工业的受害者。动物的皮被用来做时髦的衣服，而且这些衣服都是高价出售。因此，一些贪婪的人就开始大量屠杀动物。这种不负责任的行为不仅打破了自然的平衡，而且使人类居住环境陷入危险。

As far as I am concerned, something must be done to stop this illegal actionWe believe "no buying, no killing"First, we must make concerning laws to protect these animals in dangerSecond, we must take some measures to protect animals effectivelyAnimals are our friends and part of our environmentThird, we should raise people's awareness to protect animals and our environmentIn this way, we can build a harmonious society and ensure a sustainable development

在我看来，我们必须要做些什么来阻止这种违法行为。我相信“没有买，就没有杀”。首先，我们必须制定有关法律来保护这些处于危险中的动物。其次，我们必须采取一些措施有效的保护动物。动物是人类的朋友，也是我们环境的一部分。再次，我们应该提高人们保护动物和环境的意识。这样一来，我们就可以建立一个和谐的社会，确保其可持续发展。
