瑞科翻译公司小课堂——单词辨析，今天小编给大家介绍一下preface 和 introduction 的区别。

       The key difference between preface and introduction is that a preface is written by the author and tells the readers why and how the book was written, while an introduction presents the readers to the main topics of the book and prepares them for its content.

　　前言和引言之间的主要区别在于，前言由作者撰写并告诉读者这本书的写作原因和方式，而引言则向读者介绍本书的主要主题并为其内容做好准备。

　　A preface can be considered as an introduction to a book. This contains the reasons for the author to write the book, how the storyline was formed, and also the thanks and acknowledgments to people who helped the author to finish writing the book successfully. An introduction only gives a summary of the book; therefore, even before start reading, readers can get an idea as to what to expect by reading the book.

　　前言可以被视为一本书的介绍。这包含了作者写这本书的原因，故事情节是如何形成的，以及对帮助作者成功完成这本书的人的感谢和致谢。介绍只给出本书的概要；因此，即使在开始阅读之前，读者也可以通过阅读本书了解预期内容。

　　Through a preface, the readers get a first impression of the book. However, it is optional to include a preface in a book, especially if the book is short. Not all books contain prefaces, but most biographies contain them. The authors can even divide information between a preface and an introduction. In a preface, the author can raise the curiosity of the readers and increase their enthusiasm in reading the book. However, a preface should be short; if not, it would lose the readers’ interest in reading the book.

　　通过序言，读者对本书有一个初步的印象。但是，在书中包含序言是可选的，尤其是在书很短的情况下。并非所有书籍都包含序言，但大多数传记都包含它们。作者甚至可以在前言和介绍之间划分信息。在前言中，作者可以激发读者的好奇心，增加他们阅读本书的积极性。但是，前言应该简短；否则，就会失去读者阅读这本书的兴趣。

　　What is an Introduction?

The readers can have an idea about the content of the book through the introduction. A good introduction may keep the reader stick to the book, making it interesting to read. Generally, every non-fiction book contains an introduction. The introduction of a book comes just before chapter one, and since it provides an insight into the content of the book, it is important to write it attractively. Moreover, it should not be long or boring, because that will prevent the readers from reading the book. The introduction should convince the readers that the book is worth reading.  Therefore, if it is written in a way that captures the readers’ attention, the sales of the books also might go up. The author can also briefly mention the major themes of the book as well so that it will be beneficial for the readers in understanding the concepts of the story.

　　介绍也称为前言。它对任何一本书都至关重要，因为它提供了本书或文档的摘要，并对其进行了简要描述。读者可以通过引言对本书的内容有所了解。一个好的介绍可以让读者坚持读这本书，让它读起来很有趣。通常，每本非小说类书籍都包含介绍。一本书的介绍就在第一章之前，因为它提供了对本书内容的洞察，所以写得有吸引力很重要。此外，它不应该太长或无聊，因为这会妨碍读者阅读本书。引言应该让读者相信这本书值得一读。因此，如果以一种吸引读者注意力的方式编写它，书籍的销量也可能会上升。作者还可以简要提及本书的主要主题，以利于读者理解故事的概念。
