语从句译成两个表示并列或转折关系的状语从句。
This was a defensive pact, designed to protect Germany against the French,
who aspired to recover the alsace-Lorraine provinces lost in 1871, and also to protect Austria-hungary against the Russians, with whom they continually
clashed in the Balkans.
这是一个防御性的盟约，旨在保护德国人免受法国人的攻击，保护奥匈帝国免受俄国人的攻击；因为法国人想收复1871年失去的阿尔萨斯-洛林地区，而俄国人则在巴尔干半岛同奥匈帝国接连不断地发生冲突。
4．一主二仆式定语从句 一主二仆式定语从句是指一个
先行词带有两个或两个以上定语从句的情况。该结构中的定语从句比较规范，均修饰一个先行词，在翻译时，虽然也遵循一般定语从句的翻译技巧和方法，但还有其独特的地方。归纳起来，有如下几种情况：
1）译成定语 可以把两个定语从句译成并列的定语，也可译成分开的定语修饰先行词，或分别修饰重复的先行词。
… and the old ways of earning
a living rivalled by new agricultural techniques,
by commerce with hitherto unknown parts of the globe, and by new crafts with strane machines that saved
labor and that ran without the traditional human or animal power
……古老的谋生之道正受到新的农业技术、新的贸易、新的行业的
挑战；这种新贸易是与世界上一向无人知晓的地区进行的贸易，而种种新行业则是使用一些无需传统的人力畜力驱动、可节省劳动力的奇特机遇。（并列的定语）
Almost everything which really matters and which the world possessed at the commencement of the modern age was already known to man at the dawn of history.
近代史开始时，世界拥有的每一项重大成就，已为历史发端期的人们所知晓。（分开的定语）
And it helps to explain why so many inventions that were of Chinese origin
or that had been known to the Greco-Romans, were fully developed and e
xploited
ony by the Western Europeans. 它有助于说明，为什么发源于中国的许多发明和希腊罗马人所知道的许多发明，只是在西欧人手中才得到全面发展和充分利用。（分开的定语修饰重复的先行词）
2）译成并列句 可以把两个定语从句简单地译成一个并列句，也可以把它们译成两个分开的并列句，用来表示并列、转折或先后顺序等关系：
Consequently the manor was a self-sufficient vilage that was worked by serfs who were not free to leave, and who with their labor supported a hierarchy of lay and clerical lords. 因而，采邑是靠农奴经营的自足自给予的村庄；农奴不能随便离开，并以其劳动养活教俗封建集团。（一个并列句）
