机器学习代写|自然语言处理代写NLP代考|Peak Usage of Some Languages

As you might have surmised, different languages have been in an influential position during the past 2,000 years. If you trace the popularity and influence of Indo-European languages, you will find periods of time with varying degrees of influence involving multiple languages, including Hebrew, Greek, Latin, Arabic, French, and English.

Latin is an Indo-European language (apparently derived from the Etruscan and Greek alphabets), and during the lst century AD, Latin became a mainstream language. In addition, romance languages are derived from Latin. Today Latin is considered a dead language in the sense that it’s not actively spoken on a daily basis by large numbers of people. The same is true of Sanskrit, which is a very old language from India.

During the Roman Empire, Latin and Greek were the official languages for administrative as well as military activities. In addition, Latin was an important language for diplomacy among countries for many centuries after the fall of the Roman Empire.

You might be surprised to know that Arabic was the lingua franca throughout the Mediterranean during the 10th and 11th centuries AD. As another example, French was spoken in many parts of Europe during the 18th century, including the Russian aristocracy.

Today English appears to be in its ascendancy in terms of the number of native English speakers as well as the number of people who speak English as a second (or third or fourth) language. Although Mandarin is a widely spoken Asian language, English is the lingua franca for commerce as well as technology: virtually every computer language is based on English.

机器学习代写|自然语言处理代写NLP代考|Languages and Regional Accents

Accents, slang, and dialects have some common features, but there can be some significant differences. Accents involve modifying the standard pronunciation of words, which can vary significantly in different parts of the same country.

One interesting phenomenon pertains to the southern region of some countries (in the northern hemisphere), which tend to have a more “relaxed” pronunciation compared to the northern region of that country. For example, some people in the southeastern United States speak with a so-called “drawl,” whereas newscasters will often speak with a midwestern pronunciation, which is considered a neutral pronunciation. The same is true of people in Tokyo, who often speak Japanese with a “flat” pronunciation (which is also true of Japanese newscasters on NHK), versus people from the Kansai region (Kyoto, Kobe, and Osaka) of Japan, who vary the tone and emphasis of Japanese words.

Regional accents can also involve modifying the meaning of words in ways that are specific to the region in question. For example, Texans will say “I’m fixing to graduate this year” whereas people from other parts of the United States would say “going” instead of “fixing.” In France, Parisians are unlikely to say Il faut fatiguer la salade (“it’s necessary to toss the salad”), whereas this sentence is much more commonplace in southern France. (The English word “fatigue” is derived from the French verb fatiguer)

机器学习代写|自然语言处理代写NLP代考|Languages and Slang

The existence of slang words is interesting and perhaps inevitable, they seem to flourish in every human language. Sometimes slang words are used for obfuscation so that only members of an “in group” understand the modified meaning of those words. Slang words can also be a combination of existing words, new words (but not officially recognized), and short-hand expressions. Slang can also “invert” the meaning of words (“bad” instead of “good”), which can be specific to an age group, minority, or region. In addition, slang can also assign an entirely unrelated meaning to a standard word (e.g., the slang terms “that’s dope,” “that’s sick,” and “the bomb”).

Slang words can also be specific to an age group to prevent communication with members of different age groups. For example, Japanese teens can communicate with each other by reversing the order of the syllables in a word, which renders those “words” incomprehensible to adults. The inversion of syllables is far more complex than “pig Latin,” in which the first letter of a word

is shifted to the end of the word, followed by the syllable “ay.” For example, “East Bay” (an actual location in the Bay Area in Silicon Valley) is humorously called “beast” in pig Latin.

Teenagers also use acronyms (perhaps as another form of slang) when sending text messages to each other. For example, the acronym “aos” means “adult over shoulder.” The acronym “bos” has several different meanings, including “brother over shoulder” and “boyfriend over shoulder.”

The slang terms that you use with your peers invariably simplifies communication with others in your in-group, sometimes accompanied by specialized interpretations to words (such as reversing their meaning). A simple example is the word zanahoria, which is the Spanish word for carrot. In colloquial speech in Venezuela, calling someone a zanahoria means that that person is very conservative and as “straight” as a carrot.

Slang enables people to be creative and also playfully break the rules of language. Both slang and colloquial speech simplify formal language and rarely (if ever) introduce greater complexity in alternate speech rules.

Perhaps that’s the reason that slang and colloquial speech cannot be controlled or regulated by anyone (or by any language committee): like water, they are fluid and adapt to the preferences of their speakers.

One more observation: while slang can be viewed as a creative by-product of standard speech, there is a reverse effect that can occur in certain situations. For example, you have probably noticed how influential subgenres are eventually absorbed (perhaps only partially) into mainstream culture: witness how commercials eventually incorporated a “softened” form of rap music and its rhythm in commercials for personal products. There’s a certain irony in hearing “Stairway to Heaven” as elevator music.

Another interesting concept is a “meme” (which includes Internet memes) in popular culture, which refers to something with humorous content. While slang words are often used to exclude people, a meme often attempts to communicate a particular sentiment. One such meme is “OK Boomer,” which some people view as a derogatory remark that’s sometimes expressed in a snarky manner, and much less often interpreted as a humorous term. Although language dialects can also involve regional accents and slang, they also have more distinct characteristics, as discussed in the next section.

正如您可能已经猜到的那样,在过去的 2000 年中,不同的语言一直处于有影响力的位置。如果追溯印欧语系的流行程度和影响力,您会发现不同时期的影响程度不同,涉及多种语言,包括希伯来语、希腊语、拉丁语、阿拉伯语、法语和英语。

拉丁语是一种印欧语系语言(显然源自伊特鲁里亚字母和希腊字母),在公元 1 世纪,拉丁语成为主流语言。此外,浪漫语言源自拉丁语。今天,拉丁语被认为是一种死语言,因为它没有被大量的人每天主动使用。梵语也是如此,它是一种来自印度的非常古老的语言。

在罗马帝国时期,拉丁语和希腊语是行政和军事活动的官方语言。此外,在罗马帝国灭亡后的几个世纪里,拉丁语一直是各国之间外交的重要语言。

您可能会惊讶地发现,在公元 10 世纪和 11 世纪,阿拉伯语是整个地中海的通用语。另一个例子是,18 世纪欧洲许多地方都使用法语,包括俄罗斯贵族。

今天,就以英语为母语的人数以及将英语作为第二(或第三或第四)语言的人数而言,英语似乎处于优势地位。尽管普通话是一种广泛使用的亚洲语言,但英语是商业和技术的通用语言:几乎所有计算机语言都以英语为基础。

口音、俚语和方言具有一些共同特征,但也可能存在一些显着差异。口音涉及修改单词的标准发音,这在同一国家的不同地区可能会有很大差异。

一个有趣的现象与一些国家的南部地区(北半球)有关,与该国的北部地区相比,这些地区的发音往往更“轻松”。例如,美国东南部的一些人用所谓的“拖长”说话,而新闻播音员通常会用中西部发音说话,这被认为是中性发音。东京人的情况也是如此,他们说日语时经常带有“扁平”的发音(NHK 上的日本新闻播音员也是如此),而日本关西地区(京都、神户和大阪)的人则各不相同日语单词的语气和重点。

地区口音还可能涉及以特定于相关地区的方式修改单词的含义。例如,德州人会说“我准备今年毕业”,而美国其他地区的人会说“去”而不是“固定”。在法国,巴黎人不太可能说 Il faut faker la Salade(“必须扔沙拉”),而这句话在法国南部更为常见。(英文单词“fatigue”来源于法语动词failer)

俚语的存在很有趣,也许是不可避免的,它们似乎在每一种人类语言中都盛行。有时俚语被用于混淆,以便只有“组内”的成员才能理解这些词的修改含义。俚语也可以是现有词、新词(但未被官方认可)和速记表达的组合。俚语还可以“反转”单词的含义(“坏”而不是“好”),这可以特定于年龄组、少数民族或地区。此外,俚语还可以为标准词赋予完全不相关的含义(例如,俚语术语“that’s dope”、“that’s disease”和“the bomb”)。

俚语也可以是特定年龄组的,以防止与不同年龄组的成员交流。例如,日本青少年可以通过颠倒单词中的音节顺序来相互交流,这使得这些“单词”对于成年人来说是难以理解的。音节倒转比“猪拉丁语”复杂得多,其中单词的第一个字母

移到词尾,后跟音节“ay”。例如,“东湾”(硅谷湾区的一个实际位置)在猪拉丁语中被幽默地称为“野兽”。

青少年在互相发送短信时也会使用首字母缩略词(也许是另一种俚语)。例如,首字母缩略词“aos”的意思是“肩上的成人”。首字母缩略词“bos”有几种不同的含义,包括“肩上的兄弟”和“肩上的男朋友”。

您与同龄人一起使用的俚语总是简化与小组中其他人的交流,有时还伴随着对单词的专门解释(例如颠倒它们的含义)。一个简单的例子是 zanahoria 这个词,它是西班牙语中胡萝卜的意思。在委内瑞拉的口语中,称某人为 zanahoria 意味着该人非常保守,并且像胡萝卜一样“直”。

俚语使人们能够发挥创造力,也可以开玩笑地打破语言规则。俚语和口语都简化了正式语言,很少(如果有的话)在替代语音规则中引入更大的复杂性。

也许这就是俚语和口语不能被任何人(或任何语言委员会)控制或规范的原因:就像水一样,它们是流动的,可以适应说话者的偏好。

还有一个观察:虽然俚语可以被视为标准语音的创造性副产品,但在某些情况下可能会出现相反的效果。例如,您可能已经注意到有影响力的子流派最终是如何被(可能只是部分地)吸收到主流文化中:见证广告最终如何将“软化”形式的说唱音乐及其节奏融入个人产品的广告中。将“通往天堂的阶梯”作为电梯音乐听有一定的讽刺意味。

另一个有趣的概念是流行文化中的“模因”(包括互联网模因),指的是具有幽默内容的东西。虽然俚语经常被用来排斥人,但模因经常试图传达一种特定的情绪。一个这样的模因是“OK Boomer”,有些人认为这是一种贬义,有时会以一种尖刻的方式表达,而很少被解释为一个幽默的词。虽然语言方言也可能涉及地区口音和俚语,但它们也具有更鲜明的特征,如下一节所述。
