Excel如何实现局域网内共享工作簿协作Excel数据功能强大，非常好用，但平常用的时候大家总会觉得共享性比较差，不能像系统软件那样进行网络共同协作使用同一个文件。

其实，Excel也有提供局域网能共享协作的功能。

共享工作簿功能共享工作簿，可以为多用户编辑提供的现有工作簿。

但是共享工作簿并不支持所有功能，它支持以下功能：1）可以插入整行和列。

2）可以按数字、文本或日期进行排序或筛选，应用内置筛选器，然后通过使用“搜索”框进行筛选。

3）在单元格值发生变化时可以使用现有条件格式。

4）键入新值时可以使用数据验证。

5）可以查看现有图表和报表。

6）可以查看现有图片和对象。

7）可以使用现有超链接。

8）可以查看现有绘图和图形。

9）可以使用现有密码。

10）可以使用现有保护。

11）可以使用现有分级显示。

12）可以查看现有分类汇总。

13）可以查看现有模拟运算表。

14）可以查看现有报表。

15）工作簿中的现有切片器在共享工作簿后可见，但不得将其更改为独立切片器，或者重新应用于数据透视表数据或多维数据集函数。

应用于切片器的任何筛选保持不变，无论切片器在共享工作簿中是独立的还是用于数据透视表数据或多维数据集函数。

16）工作簿共享之后，工作簿中将显示现有的迷你图，并且将作出更改，以反映更新的数据。

但是，您不能创建新的迷你图、更改其数据源或修改其属性。

17）可以运行访问可用功能的现有宏。

可以将共享工作簿的操作记录到存储在其他非共享工作簿的宏中。

18）正确地计算现有数组公式。

设置共享文件夹在电脑里面设置一个共享文件夹，用来放置共享Excel文件，如建立一名为“20161024”的文件夹，然后鼠标右键菜单“属性”，进入文件夹属性设置，进行共享设置。

设置完成之后，我们就在“网络”中可以看见共享的文件夹“20161024”。

共享工作薄设置打开我们需要共享的工作薄，选择“审阅”——“共享工作薄”设置共享。

在“共享工作薄”对话框从勾选“允许多用户时编辑，同时允许工作簿合并（A）”，确定退出就好了。

新概念英语第三册第55课-From the earth Greetings

新概念英语第三册第55课:From the earth GreetingsLesson 55 From the earth: Greetings来自地球的问候 Listen to the tape then answer the question below.听录音，然后回答以下问题。

Which life forms are most likely to develop on a distant planet? Recent developments in astronomy have made it possible to detect planets in our won Milky Way and in other galaxies. This is a major achievement because, in relative terms, planets are very small and old not emit light. Finding planets is proving hard enough, but finding life on them will prove infinitely more difficult. The first question to answer is whether a planet can actually support life. In our won solar system, for example, Venus is far too hot and Mars is far too cold to support life. Only the Earth provides ideal conditions, and even here it has taken more than four billion years for plant and animal life to evolve.Whether a planet can support life depends on the size and brightness of its star, that is its 'sun'. Imagine a star up t twenty times larger, brighter, brighter and hotter than our own sun. A planet would have to be a very long way from it to be capable of supporting life. Alternatively, if the star were small, the life-supporting planet would have to have a close orbit round it and also provide the perfect conditions for life forms to develop. But how would we find such a planet? At present, there is no telescope in existence that is capable of detecting the presence of life. The development of such a telescope will be one of the great astronomical projects of the twenty-first century.It is impossible to look for life on another planet using earth-based telescopes. Our own warm atmosphere and the heat generated by the telescope would make it impossible to detect objects as small as planets.Even a telescope in orbit round the earth, like the very successful Hubble telescope, would not be suitable because of the dust particles iron solar system. A telescope would have to be as far away as the planet Jupiter to look for life in outer space, because the dust becomes thinner the further we travel towards the outer edges of our own solar system. Once we detected a planet, we would have to find a way of blotting out the light from its star, so that we would be able to 'see' the planet properly and analyze its atmosphere. In the first instance, we would be looking for plant life, rather than 'little green men'. The life forms most likely to develop on a planet would be bacteria. It is bacteria that have generated the oxygen we breathe on earth. For most of the earth's history they have been the only form of life on our planet. As Earth-dwellers, we always cherish the hope that we will be visited by little green men and that we will be able to communicate with them. But this hope is always in the realms of science fiction. If we were able to discover lowly forms of life like bacteria on another planet, it would completely change our view of ourselves. As Daniel Goldin of NASA observed, 'Finding life elsewhere would change everything. No human endeavor or thought would be unchanged by it."参考译文天文学方面最新发展使得我们能够在银河系和其他星系发现行星。

新概念英语第55课范文

新概念英语第55课范文The world has always been a place of constant change and evolution. As we navigate through the various phases of our lives, we are often confronted with new challenges and opportunities that require us to adapt and grow. One such opportunity that has become increasingly prevalent in recent years is the pursuit of learning a new language. Among the many language-learning programs available, the New Concept English series has emerged as a popular and effective choice for individuals seeking to enhance their English proficiency.The New Concept English series, which has been in existence for decades, has gained a reputation for its comprehensive and structured approach to language instruction. The program is divided into various levels, each designed to cater to the specific needs and abilities of the learner. The 55th lesson in this series, in particular, has become a cornerstone of the curriculum, offering a wealth of insights and strategies for mastering the English language.One of the key aspects of the 55th lesson in the New Concept English series is its focus on the importance of vocabulary acquisition.It is widely acknowledged that a strong vocabulary is the foundation of effective communication in any language. The lesson delves into the various techniques and strategies that can be employed to expand one's vocabulary, ranging from the use of mnemonic devices to the systematic study of word roots and affixes.The lesson also emphasizes the significance of contextual understanding when it comes to language learning. It recognizes that simply memorizing a list of words is not enough to truly grasp the nuances of a language. Instead, it encourages learners to immerse themselves in authentic language environments, such as reading literature, listening to podcasts, or engaging in conversations with native speakers. By doing so, learners can develop a deeper understanding of how words are used in real-world situations, and how their meanings can be influenced by the surrounding context.Another crucial aspect of the 55th lesson in the New Concept English series is its focus on the development of critical thinking and analytical skills. The lesson recognizes that language learning is not merely a process of memorization, but rather a dynamic and intellectually engaging endeavor. It encourages learners to question, analyze, and synthesize the information they encounter, rather than simply accepting it at face value.This emphasis on critical thinking is particularly valuable in the modern world, where the ability to navigate and evaluate vast amounts of information has become increasingly important. By honing these skills through the New Concept English program, learners can not only improve their language proficiency but also develop the cognitive abilities necessary to thrive in a rapidly changing global landscape.Furthermore, the 55th lesson in the New Concept English series places a strong emphasis on the importance of cultural awareness and understanding. It recognizes that language is not merely a set of grammatical rules and vocabulary, but rather a reflection of the cultural norms, values, and traditions of the people who speak it. By encouraging learners to explore the cultural contexts and nuances associated with the English language, the lesson helps to foster a deeper appreciation for the diversity and richness of the global community.This cultural awareness is not only valuable in the context of language learning but also in the broader realm of personal and professional development. As the world becomes increasingly interconnected, the ability to navigate and understand different cultural perspectives has become an essential skill for success in a wide range of fields, from business and diplomacy to education and the arts.In addition to the specific focus areas outlined above, the 55th lesson in the New Concept English series also emphasizes the importance of consistent practice and dedication. It recognizes that learning a language is a lifelong journey, and that progress is not always linear or immediate. By encouraging learners to adopt a mindset of persistence and resilience, the lesson helps to instill the necessary discipline and motivation required to achieve long-term success in language acquisition.This emphasis on consistent practice is particularly relevant in the context of the COVID-19 pandemic, which has posed significant challenges for language learners around the world. With many in-person language classes and immersion programs disrupted, learners have had to adapt to new modes of learning, such as online classes and self-study. The 55th lesson in the New Concept English series can serve as a valuable guide and source of inspiration for these learners, helping them to navigate the unique challenges of language learning in the digital age.In conclusion, the 55th lesson in the New Concept English series is a testament to the enduring value and relevance of language education in the modern world. By focusing on key areas such as vocabulary acquisition, contextual understanding, critical thinking, cultural awareness, and consistent practice, the lesson provides acomprehensive and effective framework for individuals seeking to master the English language. As we continue to navigate the ever-changing landscape of global communication and collaboration, the insights and strategies offered by this lesson will undoubtedly remain invaluable for learners of all ages and backgrounds.。

(美音版)新概念英语第三册：Lesson 55 From the earth： Greetings

（美音版）新概念英语第三册：Lesson 55 From theearth： GreetingsLesson 55 From the earth： Greetings来自地球的问候Listen to the tape then answer the question below.听录音，然后回答以下问题。

Which life forms are most likely to develop on a distant planet?Recent developments in astronomy have made it possible to detect planets in our own Milky Way and in other galaxies.天文学方面最新发展使得我们能够在银河系和其他星系发现行星。

This is a major achievement because, in relative terms, planets are very small and do not emit light.这是一个重要的成就，因为相对来说，行星很小，而且也不发光。

Finding planets is proving hard enough, but finding lifeon them will prove infinitely more difficult.寻找行星证明相当困难，但是要在行星上发现生命会变得无比艰难。

The first question to answer is whether a planet can actually support life.第一个需要解答的问题是一颗行星是否有能够维持生命的条件。

In our own solar system, for example, Venus is far toohot and Mars is far too cold to support life.举例来说，在我们的太阳系里，对于生命来说，金星的温度太高，而火星的温度则太低。
