中翻英时，英文标题中破折号和冒号的使用频率哪个更高？使用冒号有什么作用？

Answer 1

英文文章的破折号主要是连接一级标题和二级标题的，而冒号一般是对前面题目内容的解释说明或是细化概括。

Answer 2

都有，但是冒号更多吧。作用用法：
1．引出表示列举、解释或说明性的词语，翻译的时候保持：
2．引出对前文进行补充、总结或强调的词语，翻译的时候保持：
3．引出较长的正式引语或大段引语，翻译的时候是：或者，
4．用于信件或演说词中的称呼语之后（英国用法中多用逗号），翻译的时候保持：
5．用于公函、政府文件或商业函件的标题或标目之后，翻译的时候保持：

必备|标点符号如何翻译？（附使用规则）
比如2016年11月英语三级笔译实务试题原文：Harper Lee was an ordinary woman as stunned as anybody by the extraordinary success of “To Kill a Mockingbird.”
书名号
里面的双引号。“To Kill a Mockingbird”，英文中的书名通常是斜体或加引号表示或者大写就可以，因为斜体有时候看着不整齐，译文中文需要加上书名号，书名第一次出现，需要括号加注原英文名（人名也这样处理）。
还比如14年11月CATTI二级笔译英译汉真题原文：WATERLOO, Belgium --- The region around this Belgian city is busily preparing to commemorate the 200th anniversary in 2015 of one of the major battles in European military history.
里面的逗号和破折号。WATERLOO, Belgium比利时滑铁卢：这里考察英语地名从小到大，而且加个逗号，汉语里面是从大到小，不加逗号，比如Shanghai, China翻译为中国上海。这是CATTI英译汉高频翻译细节，可是我今天看了大家提交的译文，基本都这样写的：
WATERLOO, Belgium --- The region 比利时滑铁卢——：破折号的用法和翻译，这是CATTI英译汉高频翻译细节，经常用在文章或报道的开头，引出事件发生的背景（地点）。翻译的时候保持破折号即可。

2．引出对前文进行补充、总结或强调的词语，翻译的时候保持：
Judges have a double duty；They must protect the innocent and punish the guilty／ He has only one pleasure: eating.
3．引出较长的正式引语或大段引语，翻译的时候是：或者，
In his most famous speech he said: All men are created equal and must enjoy equally the rights that are inalienably theirs.
