冒号 Colon
冒号与分号Semicolon 不同，如前一课所述，分号是用来分隔 coordinate expressions，在句子中，冒号Colon 通常是介绍跟着的事物，特别用于职衔、参考资料、或时间资料上。
（1）用冒号来介绍例子、引述、阐释、或列表：
将冒号放在一完整句子（前句）之后，去介绍一系列事物、例子、或解释前句。
I）Introduce a quotation:
Independent clause containing words that introduce a quotation: “Quoted Words.”
例子：
As a project coordinator, my boss always followed the same policy: “Do what is right today; justify it later.”
II）Introduce a list:
Independent clause: listed items.
例子：
You will need the following items: hiking boots, a tent, some dried food, warm clothing, a torch, and mosquito repellent.
III）Introduce a second clause that summarizes, restates, explains or enlarge upon the first clause in the sentence:
Independent clause: summarizing or restating words.
例子：
We knew that he meant what he said: his eyes looked as blue and hard as steel.
Capitalization：
1.在冒号之后的完整引述句子 quotation 的第一个字用大写（capital letter）。
2.在冒号之后的表列事物、同位语（appositive）或任何其它非独立句子的第一个字要用小写（lowercase letter），但专有名词proper noun除外。
3.在冒号之后的独立句子或问句的第一个字则可以用大写或小写，而无论用那种写法，均须与整篇文章一致。
（2） 用冒号去分隔资料：
I） Title & subtitle
例子：
The complete title of the book is the Flaneur: A Stroll through the Paradoxes of Paris.
II） Hours, minutes, & seconds
例子：
The plane took off at 8:45p.m.
III） Memo form
例子：
To: Mr Philips Lee
From: Miss Teresa Fung
Re: Annual Meeting
IV） Salutation of formal or business letter
例子：
Dear Mrs Brown:
V） Chapters & verses of the bible
例子：
Psalms23:1-3
