B

试题分析:考查不定式的否定式和被动语态。固定搭配tell sb to do sth告诉某人做某事;否定式是tell sb not to do sth告诉某人不要做某事;本句是其被动语态的形式:be told not to do sth被告知不要做某事;句意:游客们被告知为了保护眼睛不受伤害,不能摘下墨镜。故B正确。

点评:不定式的否定式就是在不定式符号前面直接加not。所有的非谓语动词的否定式都是在前面直接加not,这一点要牢记。

tourists怎么读

"Tourists" 这个单词读音是 /u02c8tu028aru026asts/。让我们来分解这个单词的读音:1. "T" 的发音是 /t/,舌头轻触上颚,发出清晰的爆破音。2. "ou" 的发音是 /u028a/,发音类似于“短 u”的音,嘴唇略微收圆。3. "r" 的发音是 /r/,英式英语中,r 音发音较为清晰,不卷舌,美式英语中通常会卷舌。4. "i" 的发音是 /u026a/,发音类似于“短 i”的音,舌头稍微抬高。5. "sts" 的发音是 /sts/,这是一个连续发音的组合。发音类似于 /sts/,注意不要在 "s" 和 "t" 之间加入额外的元音声音。游客"Tourists" 是一个表示"游客"的英文单词,它来自名词"tourist",用于描述那些旅行到不同地方观光、度假或探索其他文化的人们。这个单词的读音是 /u02c8tu028aru026asts/,请注意第一个音节"tour"有重音。在日常生活中,我们经常会听到这个单词,特别是在旅游业发达的地区,吸引着大量的国内和国际游客。作为一个动态的行业,旅游业对于国家的经济发展和文化交流具有重要意义。游客们通常会参观著名景点、品尝当地美食、体验本土文化等。他们的到来不仅为目的地带来经济收入,还促进了文化交流和人际互动。因此,游客们在世界各地的旅行,不仅拓宽了他们的视野,也丰富了他们的生活体验。因此,将以上读音组合起来,"tourists" 的正确读音是 /u02c8tu028aru026asts/,注意最后的 /sts/ 发音要连续而不重复元音。在这个单词中,强调音节在第一音节上,读音中的 /u02c8/ 表示重音在第一个音节上。

雅思写作考官范文之外国游客与本地游客

  同学们在备考雅思作文的时候,看了多少范文呢?下面是雅思作文栏目我给大家整理的雅思写作考官范文之外国游客与本地游客,希望对同学们的雅思考试备考有所帮助!    雅思写作考官范文之外国游客与本地游客   题目:Foreign visitors should pay more than local visitors for cultural and historical attractions. To what extent do you agree or disagree with this opinion?   范文:   It is sometimes argued that tourists from overseas should be charged more than local residents to visit important sites and monuments. I completely disagree with this idea.   The argument in favour of higher prices for foreign tourists would be that cultural or historical attractions often depend on state subsidies to keep them going, which means that the resident population already pays money to these sites through the tax system. However, I believe this to be a very shortsighted view. Foreign tourists contribute to the economy of the host country with the money they spend on a wide range of goods and services, including food, souvenirs, accommodation and travel. The governments and inhabitants of every country should be happy to subsidise important tourist sites and encourage people from the rest of the world to visit them.   If travellers realised that they would have to pay more to visit historical and cultural attractions in a particular nation, they would perhaps decide not to go to that country on holiday. To take the UK as an example, the tourism industry and many related jobs rely on visitors coming to the country to see places like Windsor Castle or Saint Paulu2019s Cathedral. These two sites charge the same price regardless of nationality, and this helps to promote the nationu2019s cultural heritage. If overseas tourists stopped coming due to higher prices, there would be a risk of insufficient funding for the maintenance of these important buildings.   In conclusion, I believe that every effort should be made to attract tourists from overseas, and it would be counterproductive to make them pay more than local residents.   (269 words, band 9)

到旅游胜地的游客数量有所下降英语译文

One possible version: Dear Editor, I am Wang Ping, a senior-three student. I"m writing to tell your newspaper about something that surprises me. Nowadays no matter which tourist attraction we visit, we can always see such words as "I have visited this place" carved in walls or trees. Obviously, these words don"t go well with the surroundings. What"s more,it ruins the ancient buildings or spoils our natural environment. The reason for this is probably that some touristsdon"t have the sense of protecting our cultural heritage. But I think that we should have strict rules to disciplinethose tourists" bad behavior and they should be forced to pay for the damage. I sincerely hope that your newspaper can help urge all tourists to behave themselves while travelling. Best wishes. Yours sincerely, Wang Ping

雅思写作大作文高分范文:为什么本地人不参观博物馆

雅思写作大作文高分范文:为什么本地人不参观博物馆?雅思写作参考范文Museums and historical sites are the sanctuary where we can acquire historical knowledge and cultural heritage. However, it has become less attractive to the local recently. As well as discussing the factors contributing to this trend. This essay will try to find its solutions.博物馆和历史遗址是我们可以获得历史知识和文化遗产的避难所。然而,最近它对当地的吸引力降低了。同时也讨论了促成这一趋势的因素。这篇文章将试图找到它的解决之道。It is apparent that many local people assume that they are consciously aware of their cities. And they feel less fresh if they have appreciated such places ever before. In addition, many museum and sites are chargeable. As a result. The local prefer to enjoy their leisure time at home rather than in museum or historical sites.很明显,许多当地人认为他们有意识地意识到自己的城市。如果他们以前欣赏过这样的地方,他们会觉得不那么新鲜。此外,许多博物馆和网站都是收费的。作为一个结果。当地人更喜欢在家里享受闲暇时光,而不是在博物馆或历史景点。The inescapable fact is that Museums and historical sites are always the first option to many tourists. For one thing, they can pay the least spending as well as enjoy the most local knowledge and scenery. For another thing, the revenue of museums and historical sites account for the most local tourism. Governments are more pleased to attract tourists to these two places rather than to the locals. If this situation still continues in the future, there will be less local visiting to the museums and historical sites.不可避免的事实是,博物馆和历史遗迹一直是许多游客的首选。一方面,他们可以支付最少的开支,也可以享受当地的知识和风景。另一方面,博物馆和历史古迹的收入是当地旅游业的主要来源。政府更乐意吸引游客来这两个地方,而不是当地人。如果这种情况在将来还会继续,那么去博物馆和历史古迹的地方参观就会减少。One main solution is to enrich their diversity of activities. Museums can hold some larruping activities, such as Healthy Lecture and Civil Sporting Meeting. These activities will not only arouse the enthusiasm of citizens, but also add some color to this city. Besides, at some degree, lowing the price to draw more visits is also a feasible solution.一个主要的解决办法是丰富他们的活动多样性。博物馆可以举办一些大型活动,如健康讲座和公民体育会议等。这些活动不仅会激发市民的热情,也会给这个城市增添一些色彩。此外,在某种程度上,为了吸引更多的游客而降低票价也是一个可行的解决办法。To summarize, tourists will continuously choose museum and historical sites as their must-visits. However, it is still necessary to take some actions to maintain the local"s visiting.总而言之,游客们会不断地选择博物馆和历史景点作为他们的必去之处。然而,仍然有必要采取一些行动来维持当地的访问。

笔记本电脑没有XMP

XMP是有单独的选项的,进入bios就可以看到,如果没有的话就是笔记本没有这个功能。不同的主板位置还不一样的。X.M.P全称是ExtremeMemoryProfile,英文翻译可以理解是一种便于内存超频的技术,是Intel于2007年推出的一项技术,目前在DDR4内存广泛使用的是XMP2.0版,由Intel制定并负责认证工作。其原理十分简单,每一条XMP认证内存会有特定区域保存内存的超频数据,一般有XMP1和XMP2,可以把它理解成内存的预设配置文件。内存XMP的主要作用就是将内存频率超频,不过XMP属于在厂商设定的范围内超频,属于一种安全的超频,XMP相当于给内存写入了2套工作配置文件,开启BIOS中的XMP模式可让主板读取内存配置文件。比如内存标称频率3000MHz,那XMP模式就能让内存以3000MHz频率运行,从而发挥内存应有的性能。XMP与手动超频效果基本无异,所以可将其看作为内存的自动超频技术,十分适合小白的傻瓜式内存超频。

浅谈WBS工作分解结构法

有这样一个被经常使用的比喻,这是一个古老的问题,问:“你如何吃掉一头大象?” 回答当然是:“一次吃一口。” 完成一个大的战略目标,正如吃一头大象,是通过一层一层、一级一级的逐步分解细化为一个个小的任务单元,从而一点一点完成的。 “每一口”都是很重要的,因为有效的工作是一步一步完成的。对于一个项目来说,头脑风暴法能够帮助我们自下而上的定义“每一口咬什么”的活动,或者会采用自上而下的“分解”过程将一个项目(或者整头大象)细分为几个主要部分。无论用任何方法,目的都是开发一种项目所要进行的工作分解结构。 开发工作分解结构法(WBS)的丁斯莫尔指出:“需要一个整体观念描绘出一条成功实施企业项目管理的道路,所有这些都是从WBS开始的。” 那么,什么是WBS呢? 工作分解结构法(即Work Breakdown Structure,简称WBS) ,跟我们学习的因数分解是一个原理,就是把一个项目,按一定的原则分解,项目分解成任务,任务再分解成一项项工作,再把一项项工作分配到每个人的日常活动中,直到分解不下去为止。即:项目→任务→工作→活动。WBS是工作的一个总结,而不是工作本身,工作是构成项目的许多活动的总合。 项目WBS是组织项目实施的工作依据,是开展一切项目管理工作的依据和基础,具有十分重要的作用。那么该如何做好项目WBS?下面我们将介绍WBS的思路、方式和步骤。 如何形成WBS的思路呢? 首先要按照一定的原则分解,把项目分解成任务,再把任务分解成一项项工作,然后再把一项项工作再分配到每个人的日常活动中,直到再也分解不下去为止。就比如一个项目分为阶段一、阶段二或者子项目一等,在这阶段一、阶段二或者子项目一中它们的可交付成果由哪些构成,在实施计划的基础上,更进一步的将每项工作细化,经过细化的工作分别落实到每一个成员,落实到每一天。 说到这里,你一定认为WBS很简单了。但是要知道WBS并不能胡乱使用,进行项目WBS是要遵循一定原则的。 WBS要遵循哪些原则呢? WBS应按照实际工作经验和系统工作的方法、工程的特点、项目管理者的要求进行,其基本原则是: 1.WBS要遵循MECE原则,即对一项工作进行分解时,要做到不重复、不遗漏的分类,子工作之间要相互独立,所有的子工作要完全穷尽; 2.WBS要遵循SMART原则,即一项工作的分解要具备具体(Specific)、可量化(Measurable)、可实现(Attainable)、相关性(Relevant)、有时限(Time-bound)五个条件。每一项工作都必须要有部门和人负责,必须要有主要负责人员。每一项工作都要具体到个人,而不是分配给几个人组成的小组; 3.项目的每一个阶段应要能区分不同的责任者和不同的工作内容,应有较高的整体性和独立性; 4.可视化原则,可以分层看到每一项细化的工作;组件可以移动位置以利于编排WBS; 5)能够符合项目目标管理的要求,能方便的应用工期、质量、成本、合同、信息等手段; 6.WBS不要太多层次,以四至六层为宜,最低层次的工作包的单元成本不宜过大、工期不要太长。 清楚了WBS的分解原则,则可以动手进行工作分解了。WBS的方式有两种,分别为自上而下法,即从WBS的顶部开始分解可交付成果,和自下而上法,即指从底层的可交付成果(工作包)开始向WBS顶层汇总项目工作。常用的一般为自上而下法,步骤如下。 建立一个WBS可分为四个步骤: 1. 确定项目目标,着重于项目产生的产品、服务以及提供给客户的结果; 2. 准确确认项目所产生的产品、服务或提供给客户的结果(可交付成果或最终产品); 3.识别项目中的其他工作领域以确保覆盖100%的工作,识别若干可交付成果的领域、描述中间输出或可交付成果; 4. 进一步细分步骤1和2的每一项,使其形成顺序的逻辑子分组,直到工作要素的复杂性和成本花费成为可计划和可控制的管理单元(工作包)。 比如对宴会项目进行分解,分解结果如下图所示。分解过程为:第一层将宴会分解为客人名单、房间准备、食品和饮料、项目管理等工作;第二层以房间准备为例,将房间准备细分为清扫楼下~播放音乐等几个活动;第三层是将每一个活动落实到具体的工作负责人身上。 创建WBS时需满足几点基本要求: 1、某项任务应该在WBS中的一个地方且只应该在WBS中的一个地方出现; 2、一个WBS项只能由一个人或者一个部门负责,即使许多人都可能在其上工作,也只能由一个人负责其他人只能是参与者; 3、应让项目团队成员积极参与创建WBS,以确保WBS的一致性; 4、WBS必须在根据范围说明书正常地维护项目工作内容的同时,也能适应无法避免的变更; 5、WBS中某项任务的内容是其下所有WBS项的总和; 6、WBS必须与实际工作中的执行方式一致; 7、每个WBS项都必须文档化,以确保准确理解已包括和未包括的工作范围; 8、WBS应该有交付物,该项工作完成后有何交付物应该进行体现。 WBS通常是一种面向“成果”的“树”,其最底层是细化后的“可交付成果”。它是将项目的各项内容按其相关关系逐层进行分解,直到细化成工作内容单一、便于组织管理的工作单元为止。 学会运用WBS法,可以帮助我们保证项目结构的系统性和完整性,使得项目的形象透明化,也为后续的工作奠定了基础,更是各部门协调的手段。 学会运用WBS法,可以让我们的工作架构更加清晰,分解任务更加到位,任务落实更加高效,执行操作更加优质。

什么是量子?对人体有什么好处?

量子是指具有能量的粒子。世界上一切事物都在运动中,世界上不存在没有能量的粒子,所以说,“量子”这个概念是画蛇添足。

wbs分解需要遵守哪几项原则

答:在分解的过程中,应该注意以下8个方面。(1)WBS必须是面向可交付成果的。项目的目标是提供产品或服务,仅仅是一连串特别的活动。WBS中的各项工作是为提供可交付的成果服务的。WBS并没有明确地要求重复循环的工作,但为了达到里程碑,有些工作可能要进行多次。最明显的例子是软件测试,软件必须经过多次测试后才能作为可交付成果。(2) WBS必须符合项目的范围。WBS必须包括,也仅包括为了完成项目的可交付成果的活动。100%原则(包含原则)认为,在WBS中,所有下一级的元素之和必须100%的代表上一级元素。如果WBS没有覆盖全部的项目可交付成果,那么最后提交的产品或服务是无法让用户满意的。(3) WBS的底层应该支持计划和控制。WBS是项目管理计划和项目范围之间的桥梁,WBS的底层不但要支持项目管理计划,而且要让管理层能够监视和控制项目的进度和预算。如果将WBS分解得过于徉细,那么容易让人掉进细节中,同时可能会忽略更重要的事情,对于项目的控制成本也不利。另外,WBS如果变成了每小时的工作单,那么对于项目团队成员而言,谁也不愿意每时每刻都受到监控,而且,组织可能还需要雇佣相应的人员来完成如此之多的监控。(4) WBS中的元素必须有人负责,而且只由一个人负责,尽管实际上可能需要多个人参与。如果没有个人负责的内容,那么WBS发布后,也很少有项目团队成员能够意识到自己和其中内容上的联系。WBS和责任人可以使用工作责任矩阵来描述。在一些参考文献中,这个规定又称为独立责任原则。(5) WBS的指导。作为指导而不是原则,WBS应控制在4~6层。如果项目规模比较大,以至于WBS要超过6层,此时,可以使用项目分解结构将大项目分解成子项目,然后针对子项目来做WBS。每个级别的WBS将上一级的一个元素分为4~7个新的元素,同一级的元素的大小应该相似。一个工作单元只能从属于某个上层单元,避免交叉从属。(6) WBS应包括项目管理工作(因为管理是项目具体工作的一部分),也要包括分包出去的工作。(7) WBS的编制需要所有(主要)项目干系人的参与,需要项目团队成员的参与。各项目干系人站在白己的立场上,对同一个项目可能编制出差别较大的WBS。项目经理应该组织他们进行讨论,以便编制出一份大家都能接受的WBS。(8) WBS并非是一成不变的。在完成了WBS之后的工作中,仍然有可能需要对WBS进行修改。如果没有合理的范围控制,仅仅依靠WBS会使得后面的工作僵化。在一些参考文献中,这个问题被称为滚动分解原则希望采纳和点赞,谢谢,祝你每天好心情!
