中文摘要:翻译是一种语言活动，而语言又极为复杂。关于翻译，已有许多人在研究，许多书在谈，所以翻译也是极其深奥的学科，它所涉及的内容又深又广，需要深入的了解和研究。
英语复合句是由主句、从句构成，是英语中比较复杂的句子结构。从句的种类很多，但是根据性质和作用可以分为：名词性从句、形容词性从句（定语从句）、副词性从句（即状语从句）。
英语复合句翻译时要理清语法关系和逻辑关系，在翻译复合句时，语序调整是强制的，有些是选择性的。英汉语序主要差异在状语的语序和定语及被修饰成分的语序上，因此，语序调整主要是指词序、句序的调整。英汉语的词序有其一致性，句序是指复合句中主句和从句的时间和逻辑顺序。应该根据具体情况翻译处理。
