英语中引导目的状语从句的连词有：that，so that, in order that, for fear that, lest, for the purpose that, to the end that, in case等。应注意的是that和so that既可以引导结果状语从句，也可以引导目的状语从句。判断从句是結果还是目的状语应从下面几个方面 加以考虑：一般来说结果状语从句表示一种事实，而目的状语从句往往表示一种愿望和可能性，結果状语从句结构上很少用情态动词，而目的状语从句常用can, could， may, might等情态动词；結果状语从句一般置于主句之后，而目的状语从句放在句首或句尾均可。

1. 前置法

翻译目的状语从句应注意两个特点：如果译作汉语的‘‘为了”、“要（使)”等， 习惯上将目的状语从句译在句首。如：

* It is necessary first to convert the chemical energy into heat by combustion for the purpose that useful work from the chemical energy stored in fuels might be produced.

为了可以将储存于燃料中的化学能置转变成有用功，首先需要通过燃烧把化学能转变为热能。 

* The capacitor is consequently made up of large plates so that large electrical charges can be stored.

为了能储存大量的电荷，电容器通常用大面积的金属板来制造。

* In order that an electric current may flow in a circuit it must be complete and must consist of materials that are electrical conductors.

要使电流流过线路，线路必须是完整的，而且必须由导体组成。
