The basic guidelines for using capital letters in English appear simple enough:
在英语中使用大写字母的基本准则似乎很简单：
Capitalize the first word in a sentence.
句子中的第一个词首字母要大写。
Capitalize the pronoun.
代词要大写。
Capitalize proper nouns and most adjectives formed from proper nouns.
专有名词和大多数由专有名词构成的形容词要大写。
But things become tricky once we get down to the details. That's when even the most exhaustive style guides (such as the AP Stylebook and The Chicago Manual of Style) occasionally disagree.
但一旦我们深入到细节，就会变得很难。即使是最详尽的文体指南（如AP文体手册和芝加哥文体手册）针对大写问题，偶尔也会有不同意见。
In addition, there may be regional disagreements. As Pam Peters has observed, "British writers and editors are more inclined to use capital letters where Americans would dispense with them" (The Cambridge Guide to English Usage).
此外，可能存在地区分歧。正如帕姆·彼得斯所观察到的，“英国作家和编辑更倾向于在美国人不使用大写字母的地方使用大写字母”（《剑桥英语使用指南》）。
So don't regard these "rules" as the final word. If your organization has a house-style guide, stay in house. And if you run across a word or phrase not covered by these guidelines, consult a dictionary.
所以不要把这些“规则”当作最终定论。如果你的书库里有家庭文体指南，请留在家里。如果你遇到了这些指导方针中没有涉及的单词或短语，请查阅字典。
One final note: in these guidelines capitalize means to use upper case for the first letter of a word.
最后一点：在这些指导方针中，大写意味着用大写字母表示单词的第一个字母。
The First Word in a Sentence
句子中的第一个单词
Capitalize the first word in a sentence.
句子中的第一个词首字母要大写。
Your mother is in here with us, Karras. Would you like to leave a message? (Linda Blair as Regan in The Exorcist, 1973)
*妈和我们在一起，卡洛斯。你想留言吗？（林达·布莱尔在《驱魔者》中饰演里根，1973年）
Likewise, capitalize the first word of a quotation if it's a complete sentence: Jorge said, "The game is over." But don't capitalize the first word if the quotation is not a complete sentence: Jorge said that the game was "all but over" by the seventh inning.
同样，如果引用语是一个完整的句子，请将其首字母大写：乔治说：“比赛结束了。”；但如果引用语不是一个完整的句子，请不要将其首字母大写：乔治说第七局的比赛已经“结束了”。
Pronouns and Names of People or Characters
人或字的代词和名称
Capitalize the pronoun I.

I'm sorry, but I don't want to be an emperor. (Charlie Chaplin in The Great Dictator, 1940)

As a general rule, also capitalize the names of cultural movements, schools, and styles if those names are derived from proper nouns: Aristotelian, Reaganomics.
一般来说，如果文化运动、学校和风格的名称来源于专有名词：亚里士多德语、里根语，那么这些名称也应大写。
Titles (of People)
（人的）头衔
Capitalize titles that come before the names of particular persons and characters.
特定人物和角色的名称首字母要大写。

Although the titles of business executives aren't usually capitalized (the chairman of BP), in-house publications may choose to use capitals. In most cases, don't capitalize a title that appears after a name (Bill de Blasio, mayor of New York City) or that stands alone (a doctor, the mayor).
尽管企业高管的头衔通常不是大写的（英国石油公司主席），但内部出版物可能会选择使用大写。在大多数情况下，不要将出现在名字后面（纽约市市长Bill de Blasio）或单独出现的名字（医生、市长）大写。

Capitalize common nouns — such as road, river, and republic — only when they're part of the full name of a place. Don't capitalize these common nouns when they stand alone in follow-up references. Also, when two or more geographical names are linked in a single expression, the usual practice is to put the generic part of the names in lower case: the Atlantic and Pacific oceans. As a general rule, capitalize regions (the Eastern Shore, the Left Bank, the West End), but don't capitalize compass points (north, southeast) if they simply indicate direction or location. Don't capitalize sun and moon.
只有当普通名词（如公路、河流和共和国）是某个地方全名的一部分时，才将其大写。当这些普通名词单独出现在后续引用中时，不要大写。此外，当两个或多个地理名称以一个表达式连接时，通常的做法是将名称的通用部分放在小写中：the Atlantic and Pacific oceans.一般情况下，区域（东岸、左岸、西端）应大写，但如果罗盘点仅指示方向或位置，则不应大写（北、东南）。不要把太阳和月亮大写。
