电信革命的优点

As we all know ,from urban cities to rural areas, Almost everywhere can be seen the wire and some related equipments.This phenomenon is enough to prove that the popularity of telecommunications technology.Telecommunications technology can be used to facilitate people to communicate and learn knowledge at a distance, you do not need to leave home can know all the things.It is convenient for people ’s life.从城市到农村，随处可见铺设的电缆及相关电信设备，这一现象足以见证电信技术的普及。利用电信技术我们可以远距离与人交流学习，可以足不出户便可知道天下的事，这大大便利了人们的生活。

电信革命的缺点

Of course, in addition to the above advantages.Unavoidably, there are some shortcomings.The phenomenon of fraud become more and more common.Fraud have affected the level of people’s life.Apart from these, not anyone is skillful at telecommunications, upon one’s telecommunication products getting problems, there will be some troubles.当然了，除了以上的优点，不可避免的也会出现一些缺点。这体现在利用电信技术诈骗的人越来越多了，诈骗会对普通人带来一定的困扰。另外，懂电信技术的人并不是普通大众，一旦自己个人的电信产品出现问题，这将会是一个麻烦。自己的观点 Although telecommunications exists disadvantages, I personally support the popularity of telecommunication technology very much.I firmly believe that if everyone of us could try our best to obey rules, all of disgusting problems will be solved.我个人非常支持电信技术的普及，尽管它存在一定的缺陷。但我相信，只有我们每个人都尽到自己的责任，那些困扰我们的问题都将一一被解决。

The advantages and disadvantages of of studying abroad

Some people believe that attending a college or university in a foreign country has many advantages.They think that attending a college or university abroad can help them learn more than they can from universities in their own country, especially when they go to a developed country where they can catch up with the pace of scientific and technical advance of the world from that country' s modern lab facilities.In addition, they can pick up the latest developments of the living language there more quickly, develop their ability of coping with the routine matters such as finding a part-time job, renting a house and helping with the house work, and learn many new things to widen their views and broaden their minds.But some people don't agree to it.They think that attending a college or university in foreign country also has many disadvantages and the disadvantages outweigh the advantages.They hold that students studying in a foreign country will have more difficulties in both life and study.The most serious problem is the language barriers.They have to spend much time learning a foreign language and even if they have learned the language, they still can' t understand thoroughly what the foreigners and teachers say just because of the unfamiliar culture background and social customs.So ff they are not persons full of courage, flexibility, and determination, they are most likely to fail and learn nothing eventually.Besides, since costs and expenditure are much higher than those in their native country, most overseas students have to work for a living, and will find it impossible for them to pay all attention to studying.So it is of benefit to them if they study in their own country.The above two viewpoints, I should say, are all reasonable in some respects.But I support the first kind of people.I think people should attend a college or university in a foreign country ff they can.In this way they can learn not only the useful knowledge of science but also the culture and Customs of other nations.Besides, they can learn some new ideas and, when they come back, bring in some fresh air in our way of thinking and promote the development of our country.If nobody went to study abroad because of the disadvantages, the development of our country would be slower.2013131231 Wang Ruxia Mar.21.2015

第三篇：全球化的优缺点(英文)

Watch Out The Drawbacks of Globalisation It is fiercely argued about the globalisation whether merits outweigh drawbacks, as the progress of multinational corporations and the ampliative international trade.According to the definition given by an article named Turning Their Backs on The World(The Economics, 2009), globalisation is the procedure of integrating the movement of goods, capital and jobs in the global scope.Just as Tim(2009)mentioned, numerous famous products, such as Coca-cola, Accenture and Nike shoes, can be purchased almost all over the world.Indeed, globalisation has a significant impact on the economy, politics and culture, as a consequence, it has become an irreversible trend.Nonetheless, this essay attempts to demonstrate that the disadvantages emerged with the development of the globalisation are overweight when compared with benefits.In order to demonstrate this it will be shown that the favourable and unfavourable impacts brought by globalisation to the growth of a firm.Furthermore, the beneficial and adverse aspects influenced by the globalisation to the culture and economy of a country will also be discussed.As to the beneficial effects to a corporation, it is capable to decide on a flexible model for the futher growth which allows it to make the most use of local and overseas markets.For example, under the background of globalisation, international trade is a common form of business, therefore, the firm can select 1 to expand the business either in the local nation or across border to the appropriate nations where can help to achieve the most amount of profits, which is the main purpose of every corporation.Moreover, To expand to other countries means that has a wider market owning new customer groups with various demands, which consequently means that there hides huge business opportunities and a more generous margins.In a word, the increasing liberalization of markets all over the world are provided by globalisation to give multinational companies access to customers and profit margin unexpected, as are stated by Tim in 2009.Adversely, in despite of so many advantages, the opposite aspects can not be ignored and weigh even more.Firstly, globalisation may lead the disadvantaged companies to the situation of bankruptcy.An example about the experience of companies in Galax ,which is described in the ” Hard Truth about Helping The Losers from Globalisation ”(The Economics, 2007), is here suitable for a valid support.In order to gain better development, a firm is much difficult to avoid the fierce competition in an open and liberal economic environment.However, such environment and conditions indeed do not avail for those weaker companies with low level of technology and productivity, low quality of the staff and more backward level of management, which are easier eliminated from the market than companies with a powerful and abundant strength.Secondly, in the open globe, corporations have to bear higher risk in 2 the process of merger, acquisition or engaging normal commercial activities.Before the implementation of a commercial decision, accurate expectation of earnings and reasonable capital amount of investment should be projected according to the repeated investigation to the target market, unless it could be suffered from several types of of risks, such as credit risk, market risk and capital risk, which may cause imponderable damages to the company, even may lead to the elimination from local market.Therefore, a company should weigh the advantages and disadvantages of globalisation, especially the drawbacks, and avoid risks as much as possible.In terms of the impacts to a country, cultural elements from all corners of the world are integrated into its culture to enrich the original cultural content.It can be seen from the worldspread of festivals.Numerous Western festivals such as the Christmas, the Valentine’s Day , the April Fool’s Day are celebrated annually in China, meanwhile, Chinese traditional festivals like the Spring Festival, the Mid-autumn Day are accepted by other nations.What’s more, in the economic aspect, globalisation makes it convenient to exchange advanced financial information and accelerate capital flow.Lewis considered that globalisation provides a chance to less developed countries to improve the situations through an integration with the global economy.It was supported by Friedman, a Nobel laureate, who believed that greater wealth creation was led to by economic freedom.In addition, so-called organisations like the IMF, the 3 World Trade Organisation and the World Bank always serve amount of infrastructure fund to countries that get into financial difficulties(Lewis,2005).Altogether, globalisation produces cultural and economic benefits to a country.However, disadvantages are ineluctable.From the viewpoint of Klein(1999), globalisation will lead to ‘homogenization’.Ritzer(2004)asserted that big brands can create destruction of traditional culture of a country through the procedure of globalisation.The young will distinct alien culture with traditional culture and will be gradually diluted about some traditional opinions which are accepted by three generations or even more.Therefore, many cultural elements will disappeared as the development of cultural globalisation.Additionally, when it comes to the economic angle, the increased liquidity of capital brings about an unstable financial order, which will easily detonate economic crisis.Spreading through the economic ties, the crisis will evolve into a major crisis in a scope of globe.From other aspects, just as Lewis stressed, If the IMF and the World Bank were shut down, the developing countries would even worse duing to the diminished flow of resources served by these two international organizations.As presented above, globalisation can impact a country on the culture and economy to a significant extent.In conclusion, this essay has demonstrated that the disadvantages of globalisation impact on a firm and a nation far more significant than 4 advantages.Indeed, to a firm, globalisation provides a series of chances to expand market to multinational area and gain more profits, however, the company should also bear the risks brought by it.When considering to a country, evidence suggests that a richer content of culture can be formed through integration of global cultural elements, while it may detonate cultural homogenization.Furthermore, in economic aspect, although globalisation can service a convenience to acquire advanced information and the chance of improvement, it may cause the risk of global economic crisis and a potencial possibility of being even worse.Despite the fact that drawbacks are more than benefits, firms and nations can find an appropriate way to make the most of the advantages and to avoid disadvantages as possible.References The Economist print edition, 18th Jan 2007, ‘Hard Truths about Helping The Losers From Globalisation’.Lewis W(2005),Globalisation: Good or Bad?

重点词汇和句型

major主要的strength优点

self-motivated自我激励的weakness缺点

half-done未完成的，半成的solution解决办法

spend sometime in doing sth.做某事花费了一些时间

leisure time休闲时间

WHAT DO YOU CONSIDER YOUR MAJOR STRENGTH/ WEAKNESS?

“您认为您的最主要的优点是什么？最主要的缺点是什么？”

这是主考官们乐于提及的问题。通过您对这个问题的回答，主考官可以了解您的品质、个性、工作态度、工作方法等众多方面的问题；同时，他也想知道您都有哪些弱点，这些弱点是不是会影响到您的工作。下面我们就一起分析一下这个问题。

1.What do you consider your major strength?

May also be: What are you best at?

你最主要的优点是什么？或是：你最擅长什么？

注意如果主考官这样问你，这样的问题隐含的意思是“你能给我们公司做出怎样的贡献”，所以千万不要回答说自己擅长音乐或体育，而是要突出自己的最优秀的品质，作为雇主，是比较乐意接受有下列品质的雇员的：

A.self-motivated

(具有“自我激励”的品质会不断使你在工作中取得进步)

B.hard working and honest

(所有的雇主都喜欢“努力而诚实”的人，无论交付什么事情，都能让老板放心)

C.look for better ways of doing the work

(这证明你是个爱思考而且聪明的人，总是“寻找更好的做事方法”)

D.good interpersonal relationships

(这说明你有很好的人际关系，如果你本事再大，却和同事们和不来，也会让老板十分头疼的)总的看来，在回答你的优点的时候，努力向上述四个方面靠拢是比较稳妥的！

当然，你也可以把这些优点综合起来说：

“I do believe I possess lots of strengths.First, I have formed a habit of working under great pressure, I am a hard working man;Second, I am independent, and always try to use my own methods to solve problems;Third, I am honest.”

“我觉得我有很多优势。首先，我养成了在巨大压力下工作的习惯，工作也非常努力；还有，我工作是比较有独立性的，总是想用自己的方法来解决问题；再者，我也很诚实。”

面试官听到你有这么多他们所需要的优点，一定会对你留下更深的印象。

2.现在我们再来看看如果老板问你：

“What do you consider your major weakness?”

(你最主要的缺点是什么)

千万要小心，这里不要太实事求是地回答你的真实缺点，而要巧妙地在回答中体现出“你的缺点其实也是个优点”，这听起来有点难办，不过记住下面这个例子就可以让老板感觉到“你的缺点还是

蛮可爱”的嘛：

“I cannot leave a job half-done and usually find myself thinking of possible solutions to problems while I am driving to work or in the shower.I also know I spend too much time in my work., I can't get enough leisure time.”

让我们先来分析一下你的缺点：先你不会把工作做了一半就不管了，你会在开车上班的路上或在淋浴的时候都在思考工作。其次你也觉得自己在工作上花太多的心思，而没有了休闲的时间“。这样的”缺点“听起来还挺宝贵的呢。

要记住这段话，还要将几个句式熟记才行：

首先是leave在这里表示”让(人、)物维持在某种状态“；

half-done自然代表着”未完成的，半成的“；

那么在工作中遇到了问题自然你要想办法解决，所以solution这个表示”解决“的词自然是很受青睐，solution to/for/of都是可以的。

比如说公司的财务陷入了危机，有人就可能建议说：

Economy might be the solution to our financial troubles.意思是”节约可能是我们解决财务问题的办法“。

而spend sometime in doing sth.的句式是我们都很熟悉的了，leisure time着重于表示”从工作中解放出来而进行休息、娱乐“的时间，据说”不会休息的人就不会更好地工作"，但是在老板眼中，还是希望员工们多多地工作的！

第五篇：目前信息检索系统的优缺点

目前信息检索系统的优缺点

摘要

目前，Internet上信息检索的方式主要分为二种:即非WEB信息检索方式和WEB信息检索方式。这两种检索方式为人们及时准确地检索网络信息提供了极大的方便和可能，尤其WEB信息检索工具中的搜索引擎，它已成为人们查询网上信息最重要的检索工具，几乎成了网络信息检索工具的代称，因而本文在论述网络信息检索工具时以搜索引擎为主要代表。然而目前网络信息检索又面临一系列的挑战，如网络信息量的迅猛增加，以至人工己经无法对它们进行有效的分类、索引和利用;简单的关键词搜索;返回的信息量过大已经让用户无法承担;网络信息组织的无序性;网络信息日新月异的更变;信息媒体的多样化等等，这些都给Internet信息的获取和利用造成了极大的阻碍[1]。

引言

信息检索系统的研究是伴随着科学技术的发展和信息数量的俱增而兴起的，是指信息用户为处理解决各种问题而查找、识别、获取相关的事实、数据、文献的活动及过程，其主要研究范围包括：信息检索理论、信息检索语义、信息检索系统的构建和评价、信息检索技术和方法等。

信息检索的研究已经有多年的历史，20世纪中叶以前，信息的存储和传播主要以纸质介质为载体，信息检索的研究主要围绕文献的获取和控制展开，主要关注如何检索和利用文献中记载的信息。直到50年代，计算机被图书馆等部门广泛用来存储和管理文档，信息检索技术作为新的热点被广泛地研究。到了80年代，信息检索领域在索引模型，文档内容表示以及匹配策略等方面取得了许多突破性的研究成果，并且成功地开发了一些系统。例如Cornell大学的SMART系统和Massachusetts大学的INQUERY系统等。Web的出现为信息检索提供了一个前所未有的实验环境和应用情景，许多Web信息检索系统应运而生，例如Yahoo！，Alta-vista等[2]。

目前信息检索系统的优缺点

1.评价标准

目前，得到普遍认同的检索效果的评价标准主要有以下几个:查全率、查准率、收录范围、输出格式，其中以查全率和查准率最为重要[1]。综合国内外关于搜索引擎评价及其方法的研究，笔者将搜索引擎评价的研究方法分为以下几种。

(1)实验方法

(2)调查方法

(3)数据分析法

(4)观察法

(5)综述和评论

综合评价指标是指对搜索引擎各个方面进行考量时依据的参考标准，如

Carpineto等就提出了3个一级指标，分别为:检索界面、检索性能和检索输入。其中，检索界面包括搜索引擎存在、主页检索框、结果页面检索框以及高级检索界面等4个二级指标;检索性能有7个二级指标:大小写敏感度、词干检索、禁用词、部分匹配、短语检索、布尔逻辑检索、全站检索等;检索输出包括基于相关度的排序、标记检索式、结果建议、无死链4个二级指标[3]。

2.按照信息搜集方法和服务提供方式的不同，搜索引擎系统可以分为三大类：

2.1目录式搜索引擎：

以人工方式或半自动方式搜集信息，由编辑员查看信息之后，人工形成信息摘要，并将信息置于事先确定的分类框架中，提供目录浏览服务和直接检索服务。该类搜索引擎因为加入了人的智能，所以信息准确、导航质量高，缺点是需要人工介入、维护量大、信息量少、信息更新不及时。

这类搜索引擎的代表是：Yahoo、LookSmart、Open Directory、Go Guide等。

2.2机器人搜索引擎：

由一个称为蜘蛛（Spider）的机器人程序以某种策略自动地在互联网中搜集和发现信息，然后索引器为搜集到的信息建立索引，再由检索器根据用户的查询输入检索索引库并将查询结果返回给用户。服务方式是面向网页的全文检索服务。该类搜索引擎的优点是搜索的信息空间大，更新及时，毋需人工干预，缺点是返回信息过多，有很多无关信息，用户必须从结果中进行筛选。

这类搜索引擎的代表是：AltaVista，Northern Light，Excite，Infoseek，Inktomi，FAST/FastSearch，Lycos，Google，“天网”，悠游，OpenFind等。

2.3搜索引擎：这类搜索引擎没有自己的数据，而是将用户的查询请求同时向多个搜索引擎递交，将返回的结果进行重复排除、重新排序等处理后，作为自己的结果返回给用户。服务方式为面向网页的全文检索。这类搜索引擎的优点是返回结果更多、更全，缺点是不能充分利用所使用搜索引擎的功能，用户需要做更多的筛选。

这类搜索引擎的代表是WebCrawler，InfoMarket等[4]。

3.新一代的智能Web信息检索系统：

3.1移动agent技术

一般来说，所有用移动agent实现的系统都可以用传统的分布式技术赖实现。那么为什么要选择移动agent呢？这是因为移动agnet为解决分布式问题提供了一个统一的模式。它为分布计算带来了更多的灵活性、高效性、可靠性和可伸缩性。移动agent已成为继CORBA、DCOM后新一代分布处理技术。移动agent具有以下5个优点：

（1）节约网络带宽和减少网络延时；

（2）移动agent能够使传统的C/S计算模式下的计算任务更加动态均匀地分配；

（3）在分布式环境下，移动agent系统能实现较好的并行性即并行任务求解；

（4）基于移动agent的分布式系统具有较好的可理解性；

（5）异步移动计算能力。

3.2本体技术

本体的目标是捕获相关领域的知识，提供对该领域知识的共同理解，确定该领域内共同认可的词汇，并从不同层次的形式化模式上给出这些词语和词语间相互关系的明确定义。

本体的研究与应用主要包括3方面：(1)理论研究，主要研究概念及其分类和本体上的代数运算；(2)在信息系统中的应用研究，主要研究信息组织、信息检索和异构信息系统互操作问题，(3)本体作为一种能在知识层提供知识共享和重用的工具在语义Web中的应用[4]。

3.个性化搜索引擎技术

当前，个性化搜索引擎技术主要表现在如下两个方面:

(1)搜索引擎提供的搜索结果满足用户的个性化需求。由个性化搜索服务获得的搜索结果更加准确，使不同用户能够得到各自需要的搜索结果，同时避免出现不相关的搜索结果。个性化搜索引擎技术通过分析用户的搜索词，跟踪用户的搜索行为和环境，结合用户的需求变化和网络信息的动态变化实时更新等资料进行信息检索，从而为用户提供更为个性化的、准确的、真正需求的搜索结果。

(2)个性化搜索引擎所提供的服务和功能具有优势和特色，与通用搜索引擎不同。由于各大搜索引擎为了获得竞争优势，不断推出新的特色服务和功能，因此出现了从核心搜索衍生出的各种其他服务，如桌面搜索、地图搜索、生活搜索、RSS订阅等服务。

目前不少搜索引擎都加入了个性化服务和功能，他们提出了各种技术和方法以实现个性化搜索服务。他们主要采用了基于规则的和基于信息、过滤的推荐技术。其中，基于信息过滤的技术又包括协作过滤和基于内容的过滤。基于规则的技术允许系统管理员根据用户的动态和静态属性生成规则，规则决定了在不同情况下如何提供不同的务，一个规则本质上是一个if-then语句。该方法的优点是简单、直接，缺点是规则不能动态更新，质量难以保证，随着规则数的增加，系统将更难管理。典型的系统有IBM的Webshere，BroadVision和ILOG等。

基于内容过滤的技术利用资源和用户兴趣的相似度进行信息过滤。该方法的优点是简单、高效，缺点是不能发现用户新的兴趣，并且难以区分资源内容的质量和风格。典型的系统有 Personal web Watcher，syskill&webert，CiteSeer，和Web personalizer等。

基于协作的过滤技术是利用用户之间的相似度来进行信息过滤。该方法的优点是能发现用户新的兴趣点，但缺点是当系统用户和资源逐渐增多时，系统性能会逐渐降低;另外，在系统使用的初期，难以发现相似的用户。典型的系统有Web watcher，Let’s Browse，GrouLens，Firefly和Siteseer等。

还有其它的一些提供个性化服务的信息搜索系统同时采用了基于内容和协作过滤两种技术。如:webSIFT，FAB，Anatagonomy和Dynamicprofiler等，结合这两种过滤技术可以克服协作过滤的稀疏性难题，使用用户已浏览的内容来预测用户对其它资源的评价，进而增加资源评价的密度，再利用这些评价进行协作过滤，从而改善协作过滤的效率[5]。
