你好，
区分“美式英语”和“英式英语”有以下几个方面。
一, 从发音的角度来看
区分“美式英语”和“英式英语”的发音最具代表性的区别就是er的发音.
简单来说，在英式英语中,er的发音有些介于“俄”和“啊”之间的声音。而美式英语中,er的发音要卷舌，类似中文“儿”的发音，不过在一些俗语中发也会成浑元音。
二, 从拼写的角度来看
三, 从词汇的角度来看
四, 从语法的角度来看
1. 介词的使用
2. 时态运用的偏好
在描述最近发生的事情时，
美国人倾向于用过去的一般过去时，而英国的人更倾向于使用现在完成时。
3. get的过去分词
4. 集合名词
在英式英语中，集合名词（如委员会，政府，团队等）既可以是单数也可以是复数，但更多时候倾向于复数形式，强调组织成员。相比之下，美式英语的集合名词总是单数，强调组织是一个整体。
最后再提供一个视频让你学习。
希望回答对你有所帮助。
谢谢！

Written forms of American and British English as found in newspapers and textbooks vary little in their essential features, with only occasional noticeable differences in comparable media[1] (comparing American newspapers to British newspapers, for example). This kind of formal English, particularly written English, is often called 'standard English'.[2][3] An unofficial standard for spoken American English has also developed, as a result of mass media and geographic and social mobility, and broadly describes the English typically heard from network newscasters, commonly referred to as non-regional diction, although local newscasters tend toward more parochial forms of speech. [16] Despite this unofficial standard, regional variations of American English have not only persisted but have actually intensified, according to linguist William Labov.[citation needed]
Regional dialects in the United States typically reflect the elements of the language of the main immigrant groups in any particular region of the country, especially in terms of pronunciation and vernacular vocabulary. Scholars have mapped at least four major regional variations of spoken American English: Northern, Southern, Midland, and Western.[4] After the American Civil War, the settlement of the western territories by migrants from the east led to dialect mixing and levelling, so that regional dialects are most strongly differentiated in the eastern parts of the country that were settled earlier. Localized dialects also exist with quite distinct variations, such as in Southern Appalachia and New York.
The spoken forms of British English vary considerably, reflecting a long history of dialect development amid isolated populations. Dialects and accents vary not only among the countries in the United Kingdom, England, Northern Ireland, Scotland and Wales, but also within these individual countries.
There are also differences in the English spoken by different groups of people in any particular region. Received Pronunciation (RP), which is "the educated spoken English of south-east England", has traditionally been regarded as proper English; this is also referred to as BBC English or the Queen's English. The BBC and other broadcasters now intentionally use a mix of presenters with a variety of British accents and dialects, and the concept of "proper English" is now far less prevalent.[5]
British and American English are the reference norms for English as spoken, written, and taught in the rest of the world. For instance, the English-speaking members of the Commonwealth often closely follow British English forms while many new American English forms quickly become familiar outside of the United States. Although the dialects of English used in the former British Empire are often, to various extents, based on British English, most of the countries concerned have developed their own unique dialects, particularly with respect to pronunciation, idioms, and vocabulary; chief among them are Canadian English and Australian English, which rank third and fourth in number of native speakers
