英文合同的前言部分和证明部分
一、前言(Preamble)部分：
前言(Preamble)又分为合同方（Parties）和叙述（Recital）两部分，合同方（Parties）部分主要载明合同当事人的名称或者姓名、国籍、主营业所在地或住所地以及合同签订的日期等内容，通常有两种句型： 一种是完整的句子，以 This Contract is made on____, 19____, by and between ABC Company Ltd. (hereinafter called Party A) and XYZ Company Ltd. (hereinafter called Party B).为代表。 另一种则是由名词主语加动词过去分词构成的短语，以 Agreement made this _____day of _____, between _____ (hereinafter called "Licensor"), and ____(hereinafter called Licensee"):为代表。 其中，made 后常用 entered/concluded into 等，用 this 后直接用日，或者用 on后接方式较为灵活，但接日更为正式。而表达合同各方时还成对出现 of /as one part(y), of/as the other part(y), 或是of/as one hand, of/as the other hand.而表示“以下简称”时通常用（hereinafter） called 或是 hereinafter referred as to, 甚至有直接把简称写到括号里的情形。
