每空限填三词Doing "Clean "ExerciseWhen you go for a run outside, chances are that you'll find litter all around you. Do you just go past it, or do you stop and pick it up? If you choose the second, you're part of the latest popular sport in the West: plogging. The word “logging”is the Swedish phrase“plocka upp”(pick up)and the English word ”Jogging”(running slowly)put together.What a plogger needs is a rubbish bag and a pair of gloves to protect your hands. While collecting rubbish, loggers learn to classify (分类)and deal with it correctly, too.Plogging seems simple but it does a lot of good to both the environment and your health. It can not only make the world greener, but also get you full body exercise, For example, a 30-minute logging burns around 288 calories(卡路里),compared to 235 calories burnedfrom just jogging.So next time you go out jogging, why not carry a rubbish bag and collect some litter along the way?

题型二阅读理解(任务型阅读)1-10Passage 1(2018.河北)Artificial intelligence( AI)(人工智能)is growing rapidly. We are living in a world that depends more and more on AI. AI is a group of technologies that help machines get, understand and use information to do tasks.AI's recent developments have got a lot of social attention. Some people have welcomed AI because it makes things possible. For example, AI will have a big influence on areas like medicine and engineering. But this attention has also produced a lot of fear. Especially, many workers are worrying that AI could make them lose their jobs.According to a recent study, nearly five percent of jobs will disappear because of AI. In some industries,AI is already doing the work that people used to do, such as assembling(装配)cars, digging the coal and lifting goods. Self- driving cars and trucks controlled by AI will also take away the driver's jobs in the future.On the other hand, AI will also create many new jobs for people. More people will be needed to write programmes for AI systems(系统)and they will set up and work on them, too. Meanwhile, jobs that require feelings, excellent communication skills with people will not be replaced(取代)by AI. These includes jobs in fields like teaching, nursing and personal training.AI is here.

英译汉英汉互译摘要:一、英译汉的发展历程1.古代的英译汉2.近现代的英译汉3.当代的英译汉二、英汉互译的重要性1.促进国际交流2.推动经济发展3.丰富文化多样性三、英译汉的方法和技巧1.直译与意译2.词汇的对应与转换3.文化背景的理解与处理四、我国英译汉的现状与挑战1.英译汉市场的需求2.专业人才的培养3.技术进步带来的影响五、展望英译汉的未来发展1.人工智能在英译汉中的应用2.全球化背景下的英译汉需求3.英译汉行业的规范化与标准化正文:英译汉,即英语翻译成汉语,是翻译领域中的重要分支。
自古以来,英译汉就一直在不同历史时期发挥着重要作用。
在古代,英译汉主要依靠传教士和文化交流来推动。
例如,19 世纪初,英国传教士马礼逊(Robert Morrison)将《圣经》翻译成汉语,成为我国翻译史上的重要里程碑。
近现代,随着我国与世界的联系日益紧密,英译汉的需求迅速增长。
许多著名的翻译家如严复、林纾、鲁迅等,都为英译汉的发展作出了巨大贡献。
进入当代,随着全球化的推进,英译汉在政治、经济、科技、文化等领域的应用更加广泛。
我国政府高度重视英译汉工作,制定了一系列政策和规划来推动英译汉事业的发展。
英汉互译在促进国际交流、推动经济发展、丰富文化多样性等方面具有重要意义。
在国际交往中,英译汉帮助人们跨越语言障碍,增进相互了解。
在经济发展中,英译汉为国际贸易、投资和技术合作提供了重要支持。
在文化交流中,英译汉使得不同国家的优秀文化得以传播和交流,丰富了人类文明的多样性。
英译汉的方法和技巧多种多样。
直译与意译是两种基本的翻译方法。
直译强调忠实于原文,而意译则注重传达原文的意义。
在英译汉过程中,译者需要灵活运用这两种方法,根据具体情况进行选择。
此外,词汇的对应与转换、文化背景的理解与处理等也是英译汉过程中需要注意的技巧。
当前,我国英译汉面临诸多挑战,如英译汉市场的需求不断扩大,专业人才的培养亟待加强,以及技术进步带来的影响等。
人工智能机器翻译的研究与应用人工智能机器翻译(Machine Translation,MT)是将计算机技术应用于自然语言翻译的一种方式,其研究已经有数十年的历史。
近年来,随着人工智能技术的快速发展,机器翻译的质量和效率也得到了显著提高,并广泛应用于商务、教育、政府和科技等领域。
本文将从研究和应用两个角度探讨人工智能机器翻译的现状、挑战和前景。
一、研究1.历史机器翻译的研究可以追溯到20世纪50年代,当时主要采用基于规则的方法,将语言转化为形式化的结构,再通过计算机程序进行翻译。
然而,由于现代语言过于复杂、变化多端,基于规则的机器翻译方法很难达到高质量的翻译效果。
随着统计机器翻译的崛起,该领域在2000年代进入了一个新的时代。
统计机器翻译是一种基于大量语料库的方法,能够在不用规则的情况下找到最准确的翻译结果。
最近,深度神经网络的引入使机器翻译的效果得到了更进一步的提升。
2.技术机器翻译技术主要包括两个重要的步骤:第一步是语言的表示和对齐,目的是将原始语言转化为计算机能够理解的形式,并确定每个单词或短语之间的对应关系。
第二步是使用具体方法进行翻译和输出,通常包括统计机器翻译、神经网络模型等。
其中,最先进的机器翻译技术是深度学习方法,这种方法可以将大量的语言数据作为输入,从而学习到语言的特征和规律,从而实现高质量的翻译效果。
3.挑战机器翻译仍然面临很多挑战。
其中最重要的挑战是如何克服语言差异和复杂性。
不同语种之间的巨大差异,包括词汇、语法和文化等,使得机器翻译难以实现高水平的跨语言翻译。
此外,人类语言也存在很多歧义和模糊性,对于计算机来说,容易发生误解和错误翻译。
同时,机器翻译所需要的大量训练数据也存在问题,即使是现代语言也难以建立起足够大的语言资源库。
4.前景尽管面临很多挑战,但机器翻译的前景仍然十分广阔。
技术的进步和数据的增加将使机器翻译越来越准确,通过更多的训练和改进,机器翻译将逐渐接近或超越人类的翻译水平。
1.1intelligence智能:字典定义:有一种学习和应用知识的能力,一种思考和推理的本领,领会并且得益于经验的能力,这些都是有道理的。
如果我们想量化一些东西,我们将用到一些东西,像为了在环境中更好的完成任务使能力适应知识AI人工智能:作为一个学习和构造智能体程序,为了一个智能体结构在被给的环境中可以更好的完成任务1.4Does this mean that AI is impossible? 不是,人工智能系统应避免解决一些难驾驭的问题,通常这意味着人工智能系统只能作出最好的行为,有时人工智能擅长解决一些结构化的实例,也许需要一些背景知识的帮助,人工智能系统应尝试做一些相同的事情1.11 ―surely computers cannot be intelligent-they can do only what their programmers tell them.‖ Is the latter statement true, and does it imply the former?This depends on your definition of “intelligent” and “tell.” In one sense computers only do what the programmers command them to do, but in another sense what the programmers consciously tells the computer to do often has very little to do with what the computer actually does. Anyone who has written a program with an ornery bug knows this, as does anyone who has written a successful machine learning program. So in one sense Samuel “told” the computer “learn to play checkers better than I do, and then play that way,” but in another sense he told the computer “fol low this learning algorithm” and it learned to play. So we’re left in the situation where you may or may not consider learning to play checkers to be s sign of intelligence (or you may think that learning to play in the right way requires intelligence, but not in this way), and you may think the intelligence resides in the programmer or in the computer 2.1 agent智能体:在一个环境中对一个对象作出反应的实体Agent function:智能体函数:智能体相应任何感知序列所采取的行动Agent program:智能体程序:与机器结构相结合,并且实现一个智能体函数的程序,在简单的设计下,程序将为一个新的感知调用,并返回一个动作。
专升本英语作文范文——AI人工智能AI出题的几个角度考法大致会从以下几个角度:(一)材料阅读作文(河南省2022年采用的模式):根据一篇AI的英文材料来自拟题目写作文。
角度可以谈AI可能对生活的影响,AI的利弊等。
下面是一个关于AI的材料,中英对照,先看英文,看看自己是否能读懂。
然后结合汉语翻译,对AI有一个初步认识,做到即使考试也心中有数。
【材料作文】(20分)请阅读下列材料,并结合材料写一篇不少于120词的英文作文,题目自拟。
Artificial Intelligence (AI) tends to revolutionize various aspects of human life, including healthcare, finance, and entertainment. While AI has the potential to automate mundane tasks and free up time for more critical work, its rapid development also raises concerns about its impact on employment, privacy, and security. It is important to ensure that the development and deployment of AI are guided by ethical and legal frameworks that account for both its benefits and risks.(译文)人工智能(AI)倾向于革新人类生活的各个方面,包括医疗保健、金融和娱乐。
虽然AI有潜力自动化琐碎的任务并释放更多时间用于更重要的工作,但其快速发展也引发了人们对其对就业、隐私和安全的影响的担忧。
重要的是要确保AI的开发和部署受到道德和法律框架的指导,这些框架考虑到其利益和风险。
人工智能翻译实现多语种的智能翻译服务随着全球化的发展,多语种交流变得越来越重要。
然而,语言障碍一直是人们不得不面对的问题。
幸好,随着人工智能的快速发展,现在可以通过人工智能翻译来实现多语种的智能翻译服务,极大地方便了人们的交流。
一、人工智能翻译的基本原理人工智能翻译是通过计算机技术和人工智能算法将一种语言的文字、口语或录音转化为另一种语言的过程。
其基本原理是通过大数据和机器学习算法,训练计算机来理解和翻译不同语言之间的差别和规则。
使用人工智能翻译服务并不复杂,用户只需将待翻译的文字、语音或图片输入到翻译平台,人工智能算法就会自动分析并将其翻译成用户所需的目标语言。
当然,人工智能翻译也存在一些限制,例如在涉及特殊领域的专业术语翻译时可能会出现困难,但随着技术的进步,这些问题正在逐渐解决。
二、人工智能翻译的优势相比传统的翻译方式,人工智能翻译有许多优势。
首先,人工智能翻译能够实现快速、准确的翻译。
传统翻译需要花费大量的时间和人力,而人工智能翻译可以在短时间内完成大量的翻译任务,并且准确度也比较高。
其次,人工智能翻译服务覆盖的语种非常广泛。
有些语言的学习和掌握并不容易,但通过人工智能翻译服务,不同语言之间的交流变得更加容易。
无论是英语、法语、德语还是汉语、阿拉伯语等,人工智能翻译都能提供高质量的翻译服务。
再者,人工智能翻译还具有可扩展性。
由于人工智能算法的不断学习和进化,翻译质量也在不断提高。
而且,随着新的语言的学习和研究,人工智能翻译服务将会扩展到更多语种,使得多语种交流更加顺畅。
三、人工智能翻译在各领域的应用人工智能翻译的应用范围非常广泛。
在旅游领域,许多国家的旅游景点都提供了多语种的智能翻译导览服务,方便游客了解当地的历史和文化。
在商务交流中,人工智能翻译可以帮助商人和客户进行语言沟通,促进双方的交流与合作。
在学术研究中,人工智能翻译可以帮助研究人员快速获取国外文献的信息和研究进展。
在日常生活中,人工智能翻译也可以用于在线聊天、社交媒体等多种场景下的语言交流。
