一、不定式(短语)作目的状语


不定式(短语)作目的状语，主要用来修饰动词，表示某一动作或状态的目的。


1．t d...为了……


这种形式可置于句首(起强调作用，有逗号与句子隔开)或句尾(通常不用逗号隔开)。在句首时常译为“为了……”；在句尾时常译作“以便……，目的是……”。


T catch the early bus，I gt up early this mrning.


为了赶上早班车，我今天早上很早就起床了。


We wrk hard t be admitted t a key university.


我们努力学习，目的是考上重点大学。


[名师提醒] 不定式(短语)表示的是主语的目的，因此其逻辑主语通常是句子的主语。


[译]为了画好地图，你需要一支特殊的钢笔。


[误]T draw maps prperly，a special pen is needed.


[正]T draw maps prperly，yu need a special pen.


2．in rder t d...为了……


这种形式更能突出目的性，既可以置于句首又可以置于句尾。


In rder t lse weight，he takes exercise like crazy.


＝He takes exercise like crazy in rder t lse weight.


为了减肥，他拼命锻炼。


3．s as t d...为了……


这种形式与in rder t d...一样突出目的性，但s as t d...不能置于句首。


He clsed the windw s as t keep warm.


为了保暖他关上了窗户。


[名师提醒] 不定式的否定式均是在t前加nt。


We had better hurry up in rder/s as nt t be late fr class.


为了不上课迟到，我们最好快点。


4．不定式的复合结构作目的状语


当不定式(短语)有自己的执行者时，需用不定式的复合结构fr sb t d作状语。


He pened the dr fr the children t cme in.


他打开门以便孩子们进来。


5．目的状语从句与不定式的转换


不定式(短语)作目的状语可以与目的状语从句相互转换。


(1)当目的状语从句中的主语与主句中的主语相同时，可以直接简化为不定式或不定式短语作状语。例如：


We dressed up in rder that/s that we culd start early.


＝We dressed up in rder t/s as t start early.


我们穿戴整齐以便早点动身。


(2)当目的状语从句中的主语与主句中的主语不相同时，要用动词不定式的复合结构作状语。


I came early in rder that yu might read my reprt befre the meeting.


＝I came early fr yu t read my reprt befre the meeting.


我早点来是为了你在会前可以看我的报告。
