learn和study的区别：learn强调的是获得知识，内容或信息等结果；study强调的是学习、研究等行为的举动或过程。用法：learn是刚开始学的时候，study是学到一定程度的时候,有研究的意思。 区别 learn强调的是获得知识，内容或信息等结果，study强调的是学习、研究等行为的举动或过程。 当我们study的时候，只是说了有study的动作，并不意味我们学了东西，而当我们说learn的时候，表示我们已经学到了一些知识。 study是学习，研究的意思。是延续性动词。learn是学会，弄懂的意思。是瞬间动词。 用法 learn往往指通过学习、练习或别人的教授以获得某种知识和技能,侧重学习的成果，有“学会”，“学到”的意思。study通常指比较深入地学习，含有努力去学的意味，它侧重学习的过程,有“研究”,“钻研”的意思。

learn强调的是获得知识，内容或信息等结果，study强调的是学习、研究等行为的举动或过程。 当我们study的时候，只是说了有study的动作，并不意味我们学了东西，而当我们说learn的时候，表示我们已经学到了一些知识。 study是学习，研究的意思。“learn”是指通过学习、实践、接受教育或是亲身体验来获得知识或技能。所以说，study和learn之间的区别是：study强调的是过程，字典中给出了例子：阅读、背诵、上学等，study的目的是learn，但是目的不一定会达到。所以说我们平时的好好学习，就是用的study hard。意思就是说：好好听课，认真做作业，该背的背等。

learn的用法主要如下：一：learn+介词,如learn from（向·····学习）、learn about（了解,学习）、learn of（听说,获悉）、learn by oneself(自学）等.二：learn+名词,如learn english,learn a lesson.三：learn to do sth. 学着去做某事(在心里打算好了准备去学,还没有去)强调具体某次的动作.learn doing sth. 学习做某事(已经在学习了,现在进行时 ) 强调抽象的动作.

learn 指“初学”或在老师或师傅的指导下“学习”，其目的是为获得基础知识或技能。Study 指在老师的指导下自己对于书本上或某一领域的内容进行“学习和研究”。Learn 与study 后面都可以接名词或代词作宾语，但learn 可接动词不定式，而study 不能。 如：We have studied/learned English for about three years.我们学英语已经快三年了。 learn 可用来表示学习某人的品质、精神，从某处获得信息，而study 则不能这样用。Learn from sb. 意为“向某人学习”；learn from sth. “ 从……之中学习”learn of = hear of “听说、了解到”；learn about = hear about “知道、听说”。如：We must learn from Comrade Lei Feng.我们必须向雷锋同志学习。表示“在学校学习”时，多用study表示“在学校学习”时，多用study表示“在学校学习”时，多用study以上回答供您参考！希望对您有所帮助！ 杭州图书馆

颜文字起源日本，日文假名：カオモジ，日文罗马音：kaomoji，是在多语言符号象形元素基础之上发展起来的艺术。现在也有带中文的颜文字。在此基础之上发展起来的象形文字不仅更加自由多样，同时也形成了网络极简主义的艺术现象。多语言的文化包容性和字符多样性，让颜文字有了数以万计的单行象形文字组合形式，让颜文字发展成为独立于 ASCII art 和 JIS art 等多行符号拟图艺术的亚文化现象，最终发展成为影响全球的世界文化符号。

分析如下:PPPoE（英语：Point-to-Point Protocol Over Ethernet），以太网上的点对点协议，是将点对点协议（PPP）封装在以太网（Ethernet）框架中的一种网络隧道协议。由于协议中集成PPP协议，所以实现出传统以太网不能提供的身份验证、加密以及压缩等功能，也可用于缆线调制解调器（cable modem）和数字用户线路（DSL）等以以太网协议向用户提供接入服务的协议体系。扩展资料PPPoE服务器可以通过给内网用户分配账号来实现对内网用户网络使用的管理，结合有些路由器具备的上网行为管理功能和带宽管理功能，通常还能对用户的进行上网行为的管理。如禁止使用IM软件、P2P软件；限制游戏，下载，网页提交，代理服务等，同时也可以限制用户上下行带宽，对带宽弹性管理，分时段、分地址段管理以上所有上网行为。参考资料：百度百科-PPPoE服务器

Of the main classroom teaching students is the common participation of multilateral interaction activities. Democratic equality between teachers and students cooperation relationships, enabling classroom more liberal and open, more context, more conducive to the students involved in the initiative. Teaching teachers in the design and arrangement must pay more attention to innovative new teaching methods in order to better mobilize and bring into play the main body of students, so that they can truly become the protagonist of learning. Teaching English in the classroom, we can employ a variety of teaching methods, through a variety of channels, guide and encourage the active participation of all students, keen on innovation.

I can draw a tree. "student"s imagination and creativity will be the greatest tap, a fight draw many of the children"s drawings, in English and speak out. Such as: they would four small square and a large square and combined, said: "I can draw a big square and four small squares. I can draw a window." They will circle with a head for physical triangle, rectangle for the for legs, and said: "I can draw a circle, a triangle and two rectangles. Yes, I can draw a superman." this freedom, innovative teaching strategies, the impact of the spark of inspiration students so that students in the Liberal Imagination sky, and trained independent inquiry ability, the development of thinking, and raised thinking, enhance its ability to innovate and linguistic ability in practice.

PPPoE全称Point to Point Protocol over Ethernet，意思是基于以太网的点对点协议。拓展资料通过ADSL方式上网的计算机大都是通过以太网卡（Ethernet）与互联网相连的。同样使用的还是普通的TCP/IP方式，并没有附加新的协议。另外一方面，调制解调器的拨号上网，使用的是PPP协议，即Point to Point Protocol，点到点协议，该协议具有用户认证及通知IP地址的功能。PPP over Ethernet（PPPoE）协议，是在以太网络中转播PPP帧信息的技术，尤其适用于ADSL等方式。PPPoE工作原理：PPPoE协议的工作流程包含发现和会话两个阶段，发现阶段是无状态的，目的是获得PPPoE终结端（在局端的ADSL设备上）的以太网MAC地址，并建立一个唯一的PPPoE SESSION-ID。发现阶段结束后，就进入标准的PPP会话阶段。当一个主机想开始一个PPPoE会话，它必须首先进行发现阶段，以识别局端的以太网MAC地址，并建立一个PPPoE SESSION-ID。在发现阶段，基于网络的拓扑，主机可以发现多个接入集中器，然后允许用户选择一个。当发现阶段成功完成，主机和选择的接入集中器都有了他们在以太网上建立PPP连接的信息。直到PPP会话建立，发现阶段一直保持无状态的Client/Server（客户/服务器）模式。一旦PPP会话建立，主机和接入集中器都必须为PPP虚接口分配资源。参考资料：百度百科 PPPOE
